2 | CONCLUSION
3 | _________________________________________________________________________________________________________
4 | Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
5 | LatencyMon has been analyzing your system for 0:08:26 (h:mm:ss) on all processors.

32 | MEASURED INTERRUPT TO USER PROCESS LATENCIES
33 | _________________________________________________________________________________________________________
34 | The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

87 | _________________________________________________________________________________________________________
88 | Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
89 |
90 | NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

1 | CONCLUSION
2 | _________________________________________________________________________________________________________
3 | Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
4 | LatencyMon has been analyzing your system for 0:19:15 (h:mm:ss) on all processors.

31 | MEASURED INTERRUPT TO USER PROCESS LATENCIES
32 | _________________________________________________________________________________________________________
33 | The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

2 | ### **Summary**
3 |
4 | > **Hypothesis:** The `acpi.sys` driver explicitly pins its primary interrupt (the SCI) to CPU 0.
5 | >
6 | > **Conclusion:** **Hypothesis is false.** `acpi.sys` connects the SCI using `IoConnectInterruptEx` with `CONNECT_LINE_BASED (Version = 2)` and does **not** pass a CPU affinity. The HAL resolves a **software** affinity (on my VM it ends up as `0x3`, so CPU0+CPU1). For **hardware**, the HAL programs the IOAPIC entry for the SCI (GSI/IRQ 9) to **Lowest-priority delivery** with a **Logical** destination mask that matches that set.
7 | >
8 | > It is **not** physically pinned to CPU 0, but it persistently lands there as a result of the Windows kernel's scheduling and power management policies. The hardware is configured for "lowest priority" delivery, which includes a fair, rotating arbitration mechanism to handle ties [2]. However, the Windows scheduler frequently parks other cores during idle periods, leaving CPU 0 as the only processor in a responsive state. This effectively eliminates any tie-breaking scenario and makes CPU 0 the de facto target for the interrupt.
9 |
10 | > This report documents the end-to-end methodology used to trace the behavior from software to hardware and to fulfill my curiosity about this.
11 |
12 | ---
13 |
14 | ### 1. My Methodology
15 |
16 | I have adopted a high level approach to this, moving from high-level code down to the physical hardware state. Each step builds upon the last to formulate a clear chain of understanding.
17 |
18 | 1. **Static Analysis (Code Intent):** Reverse engineering `acpi.sys`, `ntoskrnl.exe` in IDA/Ghidra to understand the intended code path and how interrupt affinity *should* be handled.
19 | 2. **Live Kernel Debugging (Software Reality):** Intercepting key function calls in WinDbg to prove:
20 |
21 | * What parameters `acpi.sys` actually sends.
22 | * What affinity policy the kernel/HAL ultimately decides upon.
23 | 3. **Hardware State Analysis (Physical Reality):** Dumping the state of the virtual IOAPIC to prove how the interrupt is physically routed, confirming the ultimate outcome of the kernel's decision.
24 |
25 | ---
26 |
27 | ### 2. Static Analysis: The Driver's Intent
28 |
29 | I've reversed the key functions involved in ACPI interrupt setup.
30 |
31 | * **`acpi!OSInterruptVector`:** This is the function responsible for connecting the SCI. My analysis showed it calls `IoConnectInterruptEx` with a `Parameters.Version = 2` structure.
32 | * **`nt!IoConnectInterruptEx`:** The disassembly for this function shows that a Version 2 request is routed to the "line-based" connection path, which does not process a driver-supplied affinity mask.
33 | * **Conclusion:** The `acpi.sys` driver code is designed to be passive. It requests a connection without specifying an affinity, delegating the decision to the OS.
34 |
35 | 
36 |
37 | ---
38 |
39 | ### 3. Static Analysis: The Kernel's Intent
40 |
41 | After receiving the connection request from a driver, the kernel's I/O Manager uses the low-level `nt!IopConnectInterrupt` function to act on the policy decision made by the HAL. By analyzing this function, we can understand the kernel's intent for implementing that policy.
42 |
43 | * **Function Purpose:** To take the abstract connection data (including the final affinity mask from the HAL) and create the concrete kernel objects (`_KINTERRUPT`) that are physically bound to specific CPU cores.
44 |
45 | * **The Logic:**
46 |
47 | 1. **Affinity Unpacking:** The function's first action is to read the Group number and Affinity Mask from the `_IO_CONNECT_ACTIVE_CONTEXT` structure that was populated by the HAL.
48 | 2. **Per-CPU Object Creation:** The code then enters a loop that iterates through each bit set in the affinity mask. For *every valid CPU*, it allocates a `_KINTERRUPT` object and explicitly initializes it to be permanently bound to that specific CPU core using `KeInitializeInterruptEx`.
49 | 3. **Connection:** Finally, it connects this set of CPU-specific interrupt objects to the system's dispatch mechanism.
50 |
51 | * **Conclusion:** The kernel's intent is to fully honor the affinity mask provided by the HAL. It doesn't just "prefer" one core, it creates the necessary kernel objects to enable interrupt delivery to **every single processor** specified in the mask.
52 |
53 | 
54 | 
55 |
56 | ---
57 |
58 | ### 4. Live Kernel Debugging: Tracing the Policy
59 |
60 | ### Environment
61 |
62 | * **Guest OS:** Windows 11 Pro 24H2 (26100.1742)
63 | * **Hypervisor:** VMware Workstation
64 | * **vCPUs:** 4
65 | * **Debugger:** WinDbg (Preview) over **named pipe** serial KD
66 | * **Scope & applicability.** The results here are from a VMware guest using xAPIC/IOAPIC. On bare metal with **x2APIC** and/or **Interrupt Remapping (VT-d/AMD-IOMMU)**, the **programming path** (IOAPIC vs. remapping hardware) may differ, but the **policy** remains: the HAL resolves a **software eligible set**, and delivery uses **lowest-priority** semantics to one CPU in that set.
67 |
68 | #### 4.1. Proof Point #1: The ACPI Driver's Call
69 |
70 | I've set a breakpoint on `nt!IoConnectInterruptEx` and rebooted.
71 |
72 | * **Breakpoint Hit:** The debugger stopped on a call originating from `acpi!OSInterruptVector`.
73 | * **Parameter Analysis:** I've dumped the first ULONG of the parameters structure pointed to by `rcx`:
74 |
75 | ```
76 | kd> dd @rcx L1
77 | ffff.... 00000002
78 | ```
79 |
80 | * **Conclusion:** This proves that ``acpi.sys`` is using ```CONNECT_LINE_BASED (Version = 2)```, providing no affinity.
81 |
82 | 
83 |
84 | #### 4.2. Proof Point #2: The HAL's Permissive Software Policy
85 |
86 | I've set a second breakpoint on `nt!IopConnectInterrupt`, the function that acts on the HAL's decision.
87 |
88 | * **Breakpoint Hit:** The debugger stopped inside this function.
89 | * **Parameter Analysis:** The parameters are passed via an internal, undocumented structure `_IO_CONNECT_ACTIVE_CONTEXT`. By analyzing its memory layout in the debugger and cross-referencing against the values of known adjacent fields, the resolved GROUP_AFFINITY was identified at an offset of +0x20:
90 |
91 | ```
92 | kd> dq [addr]+20 L2
93 | ffff.... 00000000 00000003 00000000 00000000
94 | ```
95 |
96 | * **Conclusion:** The HAL's default software policy for this interrupt is a mask of `0x3` (CPUs 0 and 1). This proves the affinity is not hardcoded to Core 0 at the software policy level. It creates a set of eligible processors.
97 |
98 | 
99 |
100 | #### 4.3. Identifying the Hardware Interrupt Line (GSI)
101 |
102 | Now we have to conclusively determine the interrupt request (IRQ) line assigned to the ACPI System Control Interrupt (SCI) on the target system. The hypothesis is that the SCI is assigned to IRQ 9 (as per default). To prove this, we will use the Windows Kernel Debugger (WinDbg) to inspect the ACPI tables loaded in physical memory. The two key tables for this verification are:
103 |
104 | 1. **FADT (Fixed ACPI Description Table):** This table contains a field, `SCI_Interrupt`, which explicitly defines the system interrupt vector for the SCI.
105 | 2. **MADT (Multiple APIC Description Table):** This table describes the system's interrupt controller configuration. It is used to confirm that the SCI's IRQ is not being re-mapped or overridden.
106 |
107 | #### Step 1: Locating the ACPI Root Tables
108 |
109 | The first step is to locate the root of the ACPI table structure. The Extended System Description Table (XSDT) contains pointers to all other ACPI description tables. We can dump this table using the `!rsdt` debugger extension.
110 |
111 | **Command:**
112 |
113 | ```
114 | 0: kd> !rsdt
115 | ```
116 |
117 | **Output:**
118 |
119 | 
120 |
121 | From this output, we successfully identified the physical memory addresses for our tables of interest:
122 |
123 | * **FADT (listed as FACP):** `0xfbfad0b`
124 | * **MADT (listed as APIC):** `0xfbfae73`
125 |
126 | #### Step 2: Analysis of the Fixed ACPI Description Table (FADT)
127 |
128 | I've dumped the raw physical memory of the table using the `!db` (display bytes physical) command.
129 |
130 | **Command:**
131 |
132 | ```
133 | 0: kd> !db 0xfbfad0b L50
134 | ```
135 |
136 | 
137 |
138 | **Analysis:**
139 | According to the ACPI specification, the `SCI_Interrupt` field is located at offset `+0x2E` from the start of the FADT [1]. We can locate this value in the memory dump:
140 |
141 | * Start Address: `0xfbfad0b`
142 | * Offset: `+0x2E`
143 | * Target Address: `0xfbfad39`
144 |
145 | Examining the third line of the output, which starts at `...ad2b`, we can count forward to find the byte at `...ad39`.
146 |
147 | 
148 |
149 | The value at this location is **`0x09`**. This confirms that the FADT specifies interrupt vector 9 for the SCI.
150 |
151 | #### Step 3: Analysis of the Multiple APIC Description Table (MADT)
152 |
153 | To be certain that IRQ 9 isn't being redirected, we need to inspect the MADT. We're looking for a special entry called an "Interrupt Source Override" that would remap the IRQ.
154 |
155 | **Command:**
156 |
157 | ```
158 | 0: kd> !db 0xfbfae73 L7a
159 | ```
160 |
161 | **Output Data:**
162 |
163 | 
164 |
165 | **Analysis:**
166 | The memory dump shows the entire MADT, which contains a list of entries describing the system's interrupt controllers. By walking through this list entry by entry, we can account for the entire table and see exactly how interrupts are configured.
167 |
168 | If you parse it you will see these entries for the system's processor cores (Type 0), their NMIs (Type 4), and the main IOAPIC (Type 1). Most importantly, there is only **one** "Interrupt Source Override" (Type 2) in the entire table. As seen on the last line of the dump, this entry (`02 0a 00...`) is for **ISA IRQ 0**, remapping it to global interrupt 2.
169 |
170 | After accounting for every entry in the table, our complete scan confirms there is **no override entry for IRQ 9**. Because no override exists, IRQ 9 maintains its default 1-to-1 mapping, connecting directly to Global System Interrupt 9.
171 |
172 | #### 4.4 OS-Level Verification: Confirming the GSI in Action
173 |
174 | Our analysis of the FADT and MADT tables established the hardware's blueprint: the ACPI SCI is configured to use IRQ 9. To complete the proof, we will now verify that the Windows kernel itself follows this blueprint by connecting its SCI handler to the correct Global System Interrupt (GSI).
175 |
176 | * **Method:** The interrupt parameters, including the GSI, are passed in the internal `_IO_CONNECT_ACTIVE_CONTEXT` structure. As its definition is not in public symbols, its layout must be determined empirically. This is a standard reverse engineering practice for analyzing kernel behavior. We dump the memory of this structure. Based on this live analysis, the GSI was consistently found at the offset of `+0x40`.
177 |
178 | 1. First, we retrieve the pointer to the context structure from the stack.
179 | 2. Next, we dump the memory of this structure. Through analysis of its layout, the GSI was determined to be at an offset of **`+0x40`**.
180 |
181 | * **Results:** The commands below execute this process, revealing the GSI value used by the kernel.
182 |
183 | ```
184 | 0: kd> dq @rsp+58 L1
185 | fffff806`8d73a830 fffff806`8d73a970
186 |
187 | 0: kd> dd fffff806`8d73a970+40 L1
188 |
189 | ```
190 |
191 | 
192 |
193 | * **Conclusion:** The memory dump at the `+0x40` offset clearly shows the value `0x00000009`. This confirms that the Windows kernel is requesting to connect its ACPI SCI handler to **GSI 9**. This OS-level action perfectly corroborates our hardware-level analysis, providing end-to-end proof that the ACPI SCI is operating on IRQ 9.
194 |
195 | #### 4.5. Final IOAPIC state
196 |
197 | Results show:
198 |
199 | 
200 |
201 | ```
202 | Inti09.: 03000000`0000a9b0 Vec:B0 LowestDl Lg:03000000 lvl low
203 | ```
204 |
205 | This line is a parsed representation of the 64-bit value that configures GSI 9. Let's break down what each component means, with reference to Intel's official architecture:
206 |
207 | * **`Vec:B0` (Vector):** This sets the interrupt vector to `0xB0`. When a CPU receives this interrupt, it will use this number to look up the correct handler (the ISR) in its Interrupt Descriptor Table (IDT). This corresponds to bits 0-7 of the RTE.
208 |
209 | * **`lvl low` (Trigger Mode & Polarity):** This confirms the interrupt is configured as **level-triggered** (bit 15) and **active-low** (bit 13). This is a critical setting that matches the electrical specification of the ACPI SCI, which remains asserted at a low voltage level until the OS services it.
210 |
211 | * **`LowestDl` (Delivery Mode):** This is the most important setting for our analysis. It sets the **Delivery Mode** (bits 8-10 of the RTE) to `001b`, which Intel defines as **"Lowest Priority"**. This instructs the I/O APIC *not* to send the interrupt to a fixed, predetermined CPU. Instead, it targets a group of CPUs, and the interrupt is delivered to whichever processor in that group is currently running at the lowest interrupt priority. This hardware feature is the foundation for interrupt load balancing.
212 |
213 | * **`Lg:03000000` (Destination Mode & Destination):** This defines the group of CPUs eligible to receive the interrupt.
214 | * The `Lg` signifies that the **Destination Mode** (bit 11) is set to **Logical**. In this mode, the `Destination` field (bits 56-63) is interpreted as a bitmap, where each bit represents a CPU.
215 | * The value `0x03` (`0b00000011`) is a mask where bits 0 and 1 are set. This explicitly defines the target group as **{CPU 0, CPU 1}**, perfectly matching the software affinity (`0x3`) that the HAL decided upon in section 4.2.
216 |
217 | **In summary, these hardware settings provide the definitive proof.** The I/O APIC is explicitly commanded to take any active-low, level-triggered signal on GSI 9 and deliver it as interrupt vector `0xB0` using the "Lowest Priority" delivery scheme to the logical set of processors containing CPU 0 and CPU 1.
218 |
219 | This immediately raises the next logical question: if both CPU 0 and CPU 1 are eligible targets and running at the same priority, how does the hardware decide which one gets the interrupt? This is where the processor's arbitration mechanism comes into play. [2]
220 |
221 | ---
222 |
223 | ### 5. The Question: Why Core 0 Almost Always Wins
224 |
225 | A logical question comes from the evidence: if the hardware uses a fair, rotating arbitration for tie-breaking, why does the ACPI SCI land on Core 0 nearly 100% of the time on a typical Windows system?
226 |
227 | The answer is that the hardware's tie-breaking is rarely needed because **the Windows kernel's software policies prevent a tie from ever occurring.**
228 |
229 | The IOAPIC's rule is to deliver an interrupt to the lowest-priority processor *that is able to service it*. An advanced OS like Windows heavily manages processor power states to improve efficiency.
230 |
231 | 1. **Core Parking and Idle States (C-States):** On a lightly loaded or idle system, the Windows scheduler actively works to consolidate tasks onto a minimal number of cores (usually starting with Core 0). Other cores are placed into a "parked" state, allowing them to enter deep sleep (C-states).
232 | 2. **Eliminating the Competition:** A processor in a deep C-state is not considered a ready target for an interrupt. When the SCI fires, the IOAPIC looks at its destination set (`{CPU0, CPU1}`) and finds that CPU 1 is in a deep sleep state. CPU 0, which the kernel deliberately keeps more active for system housekeeping, is the only viable target.
233 | 3. **No Tie, No Arbitration:** Since there is only one ready processor, the interrupt is sent directly to CPU 0. The hardware's fair arbitration logic is never invoked because there is no tie to break. The OS's power management strategy has created a scenario where CPU 0 is the winner by default.
234 |
235 | Therefore, the persistent targeting of CPU 0 is not a sign of hardware pinning but rather a predictable outcome of the synergy between the IOAPIC's delivery rules and the Windows scheduler's power-saving heuristics.
236 |
237 | ---
238 |
239 | ### **6. Conclusion: The Truth About the SCI and CPU 0**
240 |
241 | After a full-stack investigation from driver code down to hardware registers, the answer is definitive: **the `acpi.sys` SCI is not, by any mechanism, hard-wired or pinned to CPU 0.**
242 |
243 | The persistent observation that it lands on CPU 0 is an emergent behavior resulting from three layers of policy:
244 |
245 | 1. **The Driver is Hands-Off (`acpi.sys`):** The ACPI driver does not request a specific CPU affinity, delegating the decision to the operating system.
246 | 2. **The HAL Forms a Team (Windows HAL):** The Hardware Abstraction Layer establishes a software policy, creating a set of eligible processors for the SCI (CPUs 0 and 1 in this case). It then programs the hardware to match this policy.
247 | 3. **The OS Makes CPU 0 the Only Viable Player (Windows Scheduler):** The kernel’s power manager aggressively parks idle cores. This ensures that when an SCI occurs on a quiet system, CPU 0 is the only processor in the eligible "team" that is actually awake and ready. The IOAPIC, following its rules, delivers the interrupt to the sole available target.

1 | # The ASUS Gaming Laptop ACPI Firmware Bug: A Deep Technical Investigation
2 |
3 | ## If You're Here, You Know The Pain
4 |
5 | You own a high-end ASUS ROG laptop perhaps a Strix, Scar, or Zephyrus. It's specifications are impressive: an RTX 30/40 series GPU, a top-tier Intel processor, and plenty of RAM. Yet, it stutters during basic tasks like watching a YouTube video, audio crackles and pops on Discord calls, the mouse cursor freezes for a split second, just long enough to be infuriating.
6 |
7 | You've likely tried all the conventional fixes:
8 | - Updating every driver imaginable, multiple times.
9 | - Performing a "clean" reinstallation of Windows.
10 | - Disabling every conceivable power-saving option.
11 | - Manually tweaking processor interrupt affinities.
12 | - Following convoluted multi-step guides from Reddit threads.
13 | - Even installing Linux, only to find the problem persists.
14 |
15 | If none of that worked, it's because the issue isn't with the operating system or a driver. The problem is far deeper, embedded in the machine's firmware, the UEFI.

41 | The data clearly implicates `ACPI.sys`. However, the per-CPU data reveals a more specific pattern:
42 |
43 | ```
44 | CPU 0 Interrupt cycle time (s): 208.470124
45 | CPU 0 ISR highest execution time (μs): 536.804674
46 | CPU 0 DPC highest execution time (μs): 5,998.834725
47 | CPU 0 DPC total execution time (s): 90.558238
48 | ```
49 |
50 | CPU 0 is taking the brunt of the impact, spending over 90 seconds processing interrupts while other cores remain largely unaffected. This isn't a failure of load balancing; it's a process locked to a single core.
51 |
52 | A similar test on a Scar 15 from 2022 shows the exact same culprit: high DPC latency originating from `ACPI.sys`.
53 |
54 | 
55 |
56 | It's easy to blame a Windows driver, but `ACPI.sys` is not a typical driver. It primarily functions as an interpreter for ACPI Machine Language (AML), the code provided by the laptop's firmware (UEFI). If `ACPI.sys` is slow, it's because the firmware is feeding it inefficient or flawed AML code to execute. These slowdowns are often triggered by General Purpose Events (GPEs) and traffic from the Embedded Controller (EC). To find the true source, we must dig deeper.
57 |
58 | ## Capturing the Problem in More Detail: ETW Tracing
59 |
60 | ### Setting Up Advanced ACPI Tracing
61 |
62 | To understand what `ACPI.sys` is doing during these latency spikes, we can use Event Tracing for Windows (ETW) to capture detailed logs from the ACPI providers.
63 |
64 | ```powershell
65 | # Find the relevant ACPI ETW providers
66 | logman query providers | findstr /i acpi
67 | # This returns two key providers:
68 | # Microsoft-Windows-Kernel-Acpi {C514638F-7723-485B-BCFC-96565D735D4A}
69 | # Microsoft-ACPI-Provider {DAB01D4D-2D48-477D-B1C3-DAAD0CE6F06B}
70 |
71 | # Start a comprehensive trace session
72 | logman start ACPITrace -p {DAB01D4D-2D48-477D-B1C3-DAAD0CE6F06B} 0xFFFFFFFF 5 -o C:\Temp\acpi.etl -ets
73 | logman update ACPITrace -p {C514638F-7723-485B-BCFC-96565D735D4A} 0xFFFFFFFF 5 -ets
74 |
75 | # Then once we're done we can stop the trace and check the etl file and save the data in csv format aswell.
76 | logman stop ACPITrace -ets
77 | tracerpt C:\Temp\acpi.etl -o C:\Temp\acpi_events.csv -of CSV
78 | ```
79 |
80 | ### An Unexpected Discovery
81 |
82 | Analyzing the resulting trace file in the Windows Performance Analyzer reveals a crucial insight. The spikes aren't random; they are periodic, occurring like clockwork every 30 to 60 seconds.
83 |
84 | 
85 |
86 | Random interruptions often suggest hardware faults or thermal throttling. A perfectly repeating pattern points to a systemic issue, a timer or a scheduled event baked into the system's logic.
87 |
88 | The raw event data confirms this pattern:
89 | ```csv
90 | Clock-Time (100ns), Event, Kernel(ms), CPU
91 | 134024027290917802, _GPE._L02 started, 13.613820, 0
92 | 134024027290927629, _SB...BAT0._STA started, 0.000000, 4
93 | 134024027290932512, _GPE._L02 finished, -, 6
94 | ```
95 |
96 | The first event, `_GPE._L02`, is an interrupt handler that takes **13.6 milliseconds** to execute. For a high-priority interrupt, this is an eternity and is catastrophic for real-time system performance.
97 |
98 | Deeper in the trace, another bizarre behavior emerges; the system repeatedly attempts to power the discrete GPU on and off, even when it's supposed to be permanently active.
99 | ```csv
100 | Clock-Time, Event, Duration
101 | 134024027315051227, _SB.PC00.GFX0._PS0 start, 278μs # GPU Power On
102 | 134024027315155404, _SB.PC00.GFX0._DOS start, 894μs # Display Output Switch
103 | 134024027330733719, _SB.PC00.GFX0._PS3 start, 1364μs # GPU Power Off
104 | [~15 seconds later]
105 | 134024027607550064, _SB.PC00.GFX0._PS0 start, 439μs # Power On Again!
106 | 134024027607657368, _SB.PC00.GFX0._DOS start, 1079μs # Display Output Switch
107 | 134024027623134006, _SB.PC00.GFX0._PS3 start, 394μs # Power Off Again!
108 | ...
109 | ```
110 | ### Why This Behavior is Fundamentally Incorrect
111 |
112 | This power cycling is nonsensical because the laptop is configured for a scenario where it is impossible: **The system is in Ultimate Mode (via a MUX switch) with an external display connected.**
113 |
114 | In this mode:
115 | - The discrete NVIDIA GPU (dGPU) is the **only** active graphics processor.
116 | - The integrated Intel GPU (iGPU) is completely powered down and bypassed.
117 | - The dGPU is wired directly to the internal and external displays.
118 | - There is no mechanism for switching between GPUs.
119 |
120 | Yet, the firmware ignores MUX state nudging the iGPU path (GFX0) and, worse, engaging dGPU cut/notify logic (PEGP/PEPD) every 30-60 seconds. The dGPU in mux mode isn't just "preferred" - it's the ONLY path to the display. There's no fallback, and no alternative. When the firmware arms DGCE (power off), it's attempting something architecturally impossible.
121 |
122 | Most of the time, hardware sanity checks refuse these nonsensical commands, but even failed attempts introduce latency spikes causing audio dropouts, input lag, and accumulating performance degradation. Games freeze mid-session, videos buffer indefinitely, system responsiveness deteriorates until restart.
123 |
124 | #### The Catastrophic Edge Case
125 |
126 | Sometimes, under specific thermal conditions or race conditions, the power-down actually succeeds. When the firmware manages to power down the GPU that's driving the display, the sequence is predictable and catastrophic:
127 |
128 | 1. **Firmware OFF attempt** - cuts the dgpu path via PEG1.DGCE
129 | 2. **Hardware complies** - safety checks fail or timing aligns
130 | 3. **Display signal cuts** - monitors go black
131 | 4. **User input triggers wake** - mouse/keyboard activity
132 | 5. **Windows calls `PowerOnMonitor()`** - attempt display recovery
133 | 6. **NVIDIA driver executes `_PS0`** - GPU power on command
134 | 7. **GPU enters impossible state** - firmware insists OFF, Windows needs ON
135 | 8. **Driver thread blocks indefinitely** - waiting for GPU response
136 | 9. **30-second watchdog expires** - Windows gives up
137 | 10. **System crashes with BSOD**
138 |

177 | The crash dump confirms the thread is stuck in `win32kbase!DrvSetWddmDeviceMonitorPowerState`, waiting for the NVIDIA driver to respond. It can't because it's caught between a confused power state, windows wanting to turn on the GPU while the firmware is arming the GPU cut off.
178 |
179 | ### Understanding General Purpose Events
180 |
181 | GPEs are the firmware's mechanism for signaling hardware events to the operating system. They are essentially hardware interrupts that trigger the execution of ACPI code. The trace data points squarely at `_GPE._L02` as the source of our latency.
182 |
183 | A closer look at the timing reveals a consistent and problematic pattern:
184 | ```
185 | _GPE._L02 Event Analysis from ROG Strix Trace:
186 |
187 | Event 1 @ Clock 134024027290917802
188 | Duration: 13,613,820 ns (13.61ms)
189 | Triggered: Battery and AC adapter status checks
190 |
191 | Event 2 @ Clock 134024027654496591
192 | Duration: 13,647,255 ns (13.65ms)
193 | Triggered: Battery and AC adapter status checks
194 |
195 | Event 3 @ Clock 134024028048493318
196 | Duration: 13,684,515 ns (13.68ms)
197 | Triggered: Battery and AC adapter status checks
198 |
199 | Interval between events: ~36-39 seconds
200 | Consistency: The duration is remarkably stable and the interval is periodic.
201 | ```
202 |
203 | ### The Correlation
204 |
205 | Every single time the lengthy `_GPE._L02` event fires, it triggers the exact same sequence of ACPI method calls.
206 |
207 | 
208 |
209 | The pattern is undeniable:
210 | 1. A hardware interrupt fires `_GPE._L02`.
211 | 2. The handler executes methods to check battery status.
212 | 3. Shortly thereafter, the firmware attempts to change the GPU's power state.
213 | 4. The system runs normally for about 30-60 seconds.
214 | 5. The cycle repeats.
215 |
216 | ## Extracting and Decompiling the Firmware Code
217 |
218 | ### Getting to the Source
219 |
220 | To analyze the code responsible for this behavior, we must extract and decompile the ACPI tables provided by the UEFI to the operating system.
221 |
222 | ```bash
223 | # Extract all ACPI tables into binary .dat files
224 | acpidump -b
225 |
226 | # Output includes:
227 | # DSDT.dat - The main Differentiated System Description Table
228 | # SSDT1.dat ... SSDT17.dat - Secondary System Description Tables
229 |
230 | # Decompile the main table into human-readable ACPI Source Language (.dsl)
231 | iasl -d dsdt.dat
232 | ```
233 | This decompiled ASL provides a direct view into the firmware's executable logic. It is a precise representation of the exact instructions that the ACPI.sys driver is fed by the firmware and executes at the highest privilege level within the Windows kernel. Any logical flaws found in this code are the direct cause of the system's behavior.
234 |
235 |
236 | ### Finding the GPE Handler
237 |
238 | Searching the decompiled `DSDT.dsl` file, we find the definition for our problematic GPE handler:
239 |
240 | ```asl
241 | Scope (_GPE)
242 | {
243 | Method (_L02, 0, NotSerialized) // _Lxx: Level-Triggered GPE
244 | {
245 | \_SB.PC00.LPCB.ECLV ()
246 | }
247 | }
248 | ```
249 | This code is simple: when the `_L02` interrupt occurs, it calls a single method, `ECLV`. The "L" prefix in `_L02` signifies that this is a **level-triggered** interrupt, meaning it will continue to fire as long as the underlying hardware condition is active. This is a critical detail.
250 |
251 | ### The Catastrophic `ECLV` Implementation
252 |
253 | Following the call to `ECLV()`, we uncover a deeply flawed implementation that is the direct cause of the system-wide stuttering.
254 |
255 | ```asl
256 | Method (ECLV, 0, NotSerialized) // Starting at line 099244
257 | {
258 | // Main loop - continues while events exist OR sleep events are pending
259 | // AND we haven't exceeded our time budget (TI3S < 0x78)
260 | While (((CKEV() != Zero) || (SLEC != Zero)) && (TI3S < 0x78))
261 | {
262 | Local1 = One
263 | While (Local1 != Zero)
264 | {
265 | Local1 = GEVT() // Get next event from queue
266 | LEVN (Local1) // Process the event
267 | TIMC += 0x19 // Increment time counter by 25
268 |
269 | // This is where it gets really bad
270 | If ((SLEC != Zero) && (Local1 == Zero))
271 | {
272 | // No events but sleep events pending
273 | If (TIMC == 0x19)
274 | {
275 | Sleep (0x64) // Sleep for 100 milliseconds!!!
276 | TIMC = 0x64 // Set time counter to 100
277 | TI3S += 0x04 // Increment major counter by 4
278 | }
279 | Else
280 | {
281 | Sleep (0x19) // Sleep for 25 milliseconds!!!
282 | TI3S++ // Increment major counter by 1
283 | }
284 | }
285 | }
286 | }
287 |
288 | // Here's where it gets even worse
289 | If (TI3S >= 0x78) // If we hit our time budget (120)
290 | {
291 | TI3S = Zero
292 | If (EEV0 == Zero)
293 | {
294 | EEV0 = 0xFF // Force another event to be pending!
295 | }
296 | }
297 | }
298 | ```
299 |
300 | ### Breaking Down this monstrosity
301 |
302 | This short block of code violates several fundamental principles of firmware and kernel programming.
303 |
304 | **Wtf 1: Sleeping in an Interrupt Context**
305 | ```asl
306 | Sleep (0x64) // 100ms sleep
307 | Sleep (0x19) // 25ms sleep
308 | ```
309 | An interrupt handler runs at a very high priority to service hardware requests quickly. The `Sleep()` function completely halts the execution of the CPU core it is running on (CPU 0 in this case). While CPU 0 is sleeping, it cannot:
310 | - Process any other hardware interrupts.
311 | - Allow the kernel to schedule other threads.
312 | - Update system timers.
313 |
314 | > Clarification: These Sleep() calls live in the ACPI GPE handling path for the GPE L02, these calls get executed at PASSIVE_LEVEL after the SCI/GPE is acknowledged so it's not a raw ISR (because i don't think windows will even allow that) but analyzing this further while the control method runs the GPE stays masked and the ACPI/EC work is serialized. With the Sleep() calls inside that path and the self rearm it seems to have the effect of making ACPI.sys get tied up in long periodic bursts (often on CPU 0) which still have the same effect on the system.
315 |
316 | **Wtf 2: Time-Sliced Interrupt Processing**
317 | The entire loop is designed to run for an extended period, processing events in batches. It's effectively a poorly designed task scheduler running inside an interrupt handler, capable of holding a CPU core hostage for potentially seconds at a time.
318 |
319 | **Wtf 3: Self-Rearming Interrupt**
320 | ```asl
321 | If (EEV0 == Zero)
322 | {
323 | EEV0 = 0xFF // Forces all EC event bits on
324 | }
325 | ```
326 | This logic ensures that even if the Embedded Controller's event queue is empty, the code will create a new, artificial event. This guarantees that another interrupt will fire shortly after, creating the perfectly periodic pattern of ACPI spikes observed in the traces.
327 |
328 | ## The Event Dispatch System
329 |
330 | ### How Events Route to Actions
331 |
332 | The LEVN() method takes an event and routes it:
333 |
334 | ```asl
335 | Method (LEVN, 1, NotSerialized)
336 | {
337 | If ((Arg0 != Zero))
338 | {
339 | MBF0 = Arg0
340 | P80B = Arg0
341 | Local6 = Match (LEGA, MEQ, Arg0, MTR, Zero, Zero)
342 | If ((Local6 != Ones))
343 | {
344 | LGPA (Local6)
345 | }
346 | }
347 | }
348 |
349 | ```
350 |
351 | ### The `LGPA` Dispatch Table
352 |
353 | The LGPA() method is a giant switch statement handling different events:
354 |
355 | ```asl
356 | Method (LGPA, 1, Serialized) // Line 098862
357 | {
358 | Switch (ToInteger (Arg0))
359 | {
360 | Case (Zero) // Most common case - power event
361 | {
362 | DGD2 () // GPU-related function
363 | ^EC0._QA0 () // EC query method
364 | PWCG () // Power change - this is our battery polling
365 | }
366 |
367 | Case (0x18) // GPU-specific event
368 | {
369 | If (M6EF == One)
370 | {
371 | Local0 = 0xD2
372 | }
373 | Else
374 | {
375 | Local0 = 0xD1
376 | }
377 | NOD2 (Local0) // Notify GPU driver
378 | }
379 |
380 | Case (0x1E) // Another GPU event
381 | {
382 | Notify (^^PEG1.PEGP, 0xD5) // Direct GPU notification
383 | ROCT = 0x55 // Sets flag for follow-up
384 | }
385 |
386 | }
387 | }
388 | ```
389 | This shows a direct link: a GPE fires, and the dispatch logic calls functions related to battery polling and GPU notifications.
390 |
391 | ## The Battery Polling Function
392 |
393 | The `PWCG()` method, called by multiple event types, is responsible for polling the battery and AC adapter status.
394 |
395 | ```asl
396 | Method (PWCG, 0, NotSerialized)
397 | {
398 | Notify (ADP0, Zero) // Tell OS to check the AC adapter
399 | ^BAT0._BST () // Execute the Battery Status method
400 | Notify (BAT0, 0x80) // Tell OS the battery status has changed
401 | ^BAT0._BIF () // Execute the Battery Information method
402 | Notify (BAT0, 0x81) // Tell OS the battery info has changed
403 | }
404 | ```
405 | Which we can see here:
406 |
407 | 
408 |
409 | Each of these operations requires communication with the Embedded Controller, adding to the workload inside the already-stalled interrupt handler.
410 |
411 | ### The GPU Notification System
412 |
413 | The `NOD2()` method sends notifications to the GPU driver.
414 |
415 | ```asl
416 | Method (NOD2, 1, Serialized)
417 | {
418 | If ((Arg0 != DNOT))
419 | {
420 | DNOT = Arg0
421 | Notify (^^PEG1.PEGP, Arg0)
422 | }
423 |
424 | If ((ROCT == 0x55))
425 | {
426 | ROCT = Zero
427 | Notify (^^PEG1.PEGP, 0xD1) // Hardware-Specific
428 | }
429 | }
430 | ```
431 | These notifications (`0xD1`, `0xD2`, etc.) are hardware-specific signals that tell the NVIDIA driver to re-evaluate its power state, which prompts driver power-state re-evaluation; in traces this surfaces as iGPU GFX0._PSx/_DOS toggles plus dGPU state changes via PEPD._DSM/DGCE.
432 |
433 |
434 | ## The Mux Mode Confusion: A Firmware with a Split Personality
435 |
436 | Here's where a simple but catastrophic oversight in the firmware's logic causes system-wide failure. High-end ASUS gaming laptops feature a MUX (Multiplexer) switch, a piece of hardware that lets the user choose between two distinct graphics modes:
437 |
438 | 1. **Optimus Mode:** The power-saving default. The integrated Intel GPU (iGPU) is physically connected to the display. The powerful NVIDIA GPU (dGPU) only renders demanding applications when needed, passing finished frames to the iGPU to be drawn on screen.
439 | 2. **Ultimate/Mux Mode:** The high-performance mode. The MUX switch physically rewires the display connections, bypassing the iGPU entirely and wiring the NVIDIA dGPU directly to the screen. In this mode, the dGPU is not optional; it is the **only** graphics processor capable of outputting an image.
440 |
441 | Any firmware managing this hardware **must** be aware of which mode the system is in. Sending a command intended for one GPU to the other is futile and, in some cases, dangerous. Deep within the ACPI code, a hardware status flag named `HGMD` is used to track this state. To understand the flaw, we first need to decipher what `HGMD` means, and the firmware itself gives us the key.
442 |
443 | #### **Decoding the Firmware's Logic with the Brightness Method**
444 |
445 | For screen brightness to work, the command must be sent to the GPU that is physically controlling the display backlight. A command sent to the wrong GPU will simply do nothing. Therefore, the brightness control method (`BRTN`) *must* be aware of the MUX switch state to function at all. It is the firmware's own Rosetta Stone.
446 |
447 | ```asl
448 | // Brightness control - CORRECTLY checks for mux mode
449 | Method (BRTN, 1, Serialized) // Line 034003
450 | {
451 | If (((DIDX & 0x0F0F) == 0x0400))
452 | {
453 | If (HGMD == 0x03) // 0x03 = Ultimate/Mux mode
454 | {
455 | // In mux mode, notify discrete GPU
456 | Notify (\_SB.PC00.PEG1.PEGP.EDP1, Arg0)
457 | }
458 | Else
459 | {
460 | // In Optimus, notify integrated GPU
461 | Notify (\_SB.PC00.GFX0.DD1F, Arg0)
462 | }
463 | }
464 | }
465 | ```
466 |
467 | The logic here is flawless and revealing. The code uses the `HGMD` flag to make a binary decision. If `HGMD` is `0x03`, it sends the command to the NVIDIA GPU. If not, it sends it to the Intel GPU. The firmware itself, through this correct implementation, provides the undeniable definition: **`HGMD == 0x03` means the system is in Ultimate/Mux Mode.**
468 |
469 | #### **The Logical Contradiction: Unconditional Power Cycling in a Conditional Hardware State**
470 |
471 | This perfect, platform-aware logic is completely abandoned in the critical code paths responsible for power management. The `LGPA` method, which is called by the stutter-inducing interrupt, dispatches power-related commands to the GPU *without ever checking the MUX mode*.
472 |
473 | ```asl
474 | // GPU power notification - NO MUX CHECK!
475 | Case (0x18)
476 | {
477 | // This SHOULD have: If (HGMD != 0x03)
478 | // But it doesn't, so it runs even in mux mode
479 | If (M6EF == One)
480 | {
481 | Local0 = 0xD2
482 | }
483 | Else
484 | {
485 | Local0 = 0xD1
486 | }
487 | NOD2 (Local0) // Notifies GPU regardless of mode
488 | }
489 | ```
490 |
491 | ### Another Path to the Same Problem: The Platform Power Management DSM
492 |
493 | This is not a single typo. A second, parallel power management system in the firmware exhibits the exact same flaw. The Platform Extension Plug-in Device (`PEPD`) is used by Windows to manage system-wide power states, such as turning off displays during modern standby.
494 |
495 | ```asl
496 | Device (PEPD) // Line 071206
497 | {
498 | Name (_HID, "INT33A1") // Intel Power Engine Plugin
499 |
500 | Method (_DSM, 4, Serialized) // Device Specific Method
501 | {
502 | // ... lots of setup code ...
503 |
504 | // Arg2 == 0x05: "All displays have been turned off"
505 | If ((Arg2 == 0x05))
506 | {
507 | // Prepare for aggressive power saving
508 | If (CondRefOf (\_SB.PC00.PEG1.DHDW))
509 | {
510 | ^^PC00.PEG1.DHDW () // GPU pre-shutdown work
511 | ^^PC00.PEG1.DGCE = One // Set "GPU Cut Enable" flag
512 | }
513 |
514 | If (S0ID == One) // If system supports S0 idle
515 | {
516 | GUAM (One) // Enter low power mode
517 | }
518 |
519 | ^^PC00.DPOF = One // Display power off flag
520 |
521 | // Tell USB controller about display state
522 | If (CondRefOf (\_SB.PC00.XHCI.PSLI))
523 | {
524 | ^^PC00.XHCI.PSLI (0x05)
525 | }
526 | }
527 |
528 | // Arg2 == 0x06: "A display has been turned on"
529 | If ((Arg2 == 0x06))
530 | {
531 | // Wake everything back up
532 | If (CondRefOf (\_SB.PC00.PEG1.DGCE))
533 | {
534 | ^^PC00.PEG1.DGCE = Zero // Clear "GPU Cut Enable"
535 | }
536 |
537 | If (S0ID == One)
538 | {
539 | GUAM (Zero) // Exit low power mode
540 | }
541 |
542 | ^^PC00.DPOF = Zero // Display power on flag
543 |
544 | If (CondRefOf (\_SB.PC00.XHCI.PSLI))
545 | {
546 | ^^PC00.XHCI.PSLI (0x06)
547 | }
548 | }
549 | }
550 | }
551 | ```
552 |
553 | Once again, the firmware prepares to cut power to the discrete GPU without first checking if it's the only GPU driving the displays. This demonstrates that the Mux Mode Confusion is a systemic design flaw. The firmware is internally inconsistent, leading it to issue self-destructive commands that try to cripple the system.
554 |
555 | ## Cross-System Analysis
556 |
557 | Traces from multiple ASUS gaming laptop models confirm this is not an isolated issue.
558 |
559 | #### Scar 15 Analysis
560 | - **Trace Duration:** 4.1 minutes
561 | - **`_GPE._L02` Events:** 7 (every ~39 seconds)
562 | - **Avg. GPE Duration:** 1.56ms
563 | - **GPU Power Cycles:** 8
564 |
565 | #### Zephyrus M16 Analysis
566 | - **Trace Duration:** 19.9 minutes
567 | - **`_GPE._L02` Events:** 3 (same periodic pattern)
568 | - **Avg. GPE Duration:** 2.94ms
569 | - **GPU Power Cycles:** 197 (far more frequent)
570 | - **ASUS WMI Calls:** 2,370 (Armoury Crate amplifying the problem)
571 |
572 | ### What Actually Breaks
573 |
574 | The firmware acts as the hardware abstraction layer between Windows and the physical hardware. When ACPI control methods execute, they run under the Windows ACPI driver with specific timing constraints and because of these timing constraints GPE control methods need to finish quickly because the firing GPE stays masked until the method returns so sleeping or polling inside a path like that can trigger real time-glitches and produce very high latency numbers, as our tests indicate.
575 |
576 | Microsoft's [Hardware Lab Kit GlitchFree test](https://learn.microsoft.com/windows-hardware/test/hlk/testref/f0ed5aa8-ef49-4fc9-99b6-753c857e4e2d) validates this hardware-software contract by measuring audio/video glitches during HD playback. It fails systems with driver stalls exceeding a few milliseconds because such delays break real-time guarantees needed for smooth media playback.
577 |
578 | These ASUS systems violate those constraints. The firmware holds GPE._L02 masked for 13ms while sleeping in ECLV, serializing all ACPI/EC operations behind that delay. It polls battery state when it should use event-driven notifications. It attempts GPU power transitions without checking platform configuration (HGMD). All these problems result in powerful hardware crippled by firmware that doesn't understand its own execution context.
579 |
580 | ### The Universal Pattern
581 |
582 | Despite being different models, all affected systems exhibit the same core flaws:
583 | 1. `_GPE._L02` handlers take milliseconds to execute instead of microseconds.
584 | 2. The GPEs trigger unnecessary battery polling.
585 | 3. The firmware attempts to power cycle the GPU while in a fixed MUX mode.
586 | 4. The entire process is driven by a periodic, timer-like trigger.
587 |
588 | ## Summarizing the Findings
589 |
590 | This bug is a cascade of firmware design failures.
591 |
592 | ### Root Cause 1: The Misunderstanding of Interrupt Context
593 |
594 | On windows, the LXX / EXX run at PASSIVE_LEVEL via ACPI.sys but while a GPE control method runs **the firing GPE stays masked** and ACPI/EC work is **serialized**. ASUS's dispatch from GPE._L02 to ECLV loops, calls Sleep(25/100ms) and re-arms the EC stretching that masked window into tens of milliseconds (which would explain the 13ms CPU time in ETW (Kernel ms) delay for GPE Events) and producing a periodic ACPI.sys burst that causes the latency problems on the system. The correct behavior is to latch or clear the event, exit the method, and signal a driver with Notify for any heavy work; do not self-rearm or sleep in this path at all.
595 |
596 | ### Root Cause 2: Flawed Interrupt Handling
597 | The firmware artificially re-arms the interrupt, creating an endless loop of GPEs instead of clearing the source and waiting for the next legitimate hardware event. This transforms a hardware notification system into a disruptive, periodic timer.
598 |
599 | ### Root Cause 3: Lack of Platform Awareness
600 | The code that sends GPU power notifications does not check if the system is in MUX mode, a critical state check that is correctly performed in other parts of the firmware. This demonstrates inconsistency and a lack of quality control.
601 |
602 | ## Timeline of User Reports
603 |
604 | ### The Three-Year Pattern
605 |
606 | This issue is not new or isolated. User reports documenting identical symptoms with high ACPI.sys DPC latency, periodic stuttering, and audio crackling have been accumulating since at least 2021 across ASUS's entire gaming laptop lineup.
607 |
608 | **August 2021: First major reports (AMD Advantage Edition)**
609 | The earliest documented case on the official ASUS ROG forums is a **G15 Advantage Edition (G513QY, all-AMD)** owner reporting ["severe DPC latency from ACPI.sys"](https://rog-forum.asus.com/t5/rog-strix-series/g15-advantage-edition-g513qy-severe-dpc-latency-audio-dropouts/m-p/809512) with audio dropouts under any load. The thread, last edited in March 2024, shows the issue remained unresolved for years.
610 |
611 | **August 2021: Parallel reports (NVIDIA-based models)**
612 | Around the same time, **separate Reddit threads on NVIDIA-based ROG models** describe [identical ACPI.sys latency problems](https://www.reddit.com/r/ASUS/comments/odprtv/high_dpc_latency_from_acpisys_can_be_caused_by/). Different GPU vendors, same firmware/ACPI failure pattern.
613 |
614 | **2021-2023: Spreading Across Models**
615 | Throughout this period, the issue proliferates across ASUS's gaming lineup:
616 | - [ROG Strix models experience micro-stutters](https://www.reddit.com/r/techsupport/comments/mxtm86/i_need_help_high_acpisys_latency_and_microstutters/)
617 | - [TUF Gaming series reports throttling for seconds at a time](https://www.reddit.com/r/Asustuf/comments/1m2e40v/my_laptop_throttling_for_few_seconds/)
618 | - [G18 models exhibit the characteristic 45-second periodic stuttering](https://www.reddit.com/r/techsupport/comments/17rqfq5/new_laptop_started_stuttering_every_45_seconds/)
619 |
620 | **2023-2024: The Problem Persists in New Models**
621 | Even the latest generations aren't immune:
622 | - [2023 Zephyrus M16 owners report persistent audio issues](https://www.reddit.com/r/ZephyrusM16/comments/1j33ld6/this_machine_has_been_nothing_but_problems_no/)
623 | - [2023 G16 models continue experiencing audio pops/crackles](https://www.reddit.com/r/ZephyrusG14/comments/1l4jb13/audio_popscrackles_on_zephyrus_g16_2023/)
624 | - [2024 Intel G16 models require workarounds for audio stuttering](https://www.reddit.com/r/ZephyrusG14/comments/1i2w9ah/resolving_audio_popsstuttering_on_2024_intel_g16/)
625 |
626 | ## Conclusion
627 |
628 | The evidence is undeniable:
629 | - **Measured Proof:** GPE handlers are measured blocking a CPU core for over 13 milliseconds.
630 | - **Code Proof:** The decompiled firmware explicitly contains `Sleep()` calls within an interrupt handler.
631 | - **Logical Proof:** The code lacks critical checks for the laptop's hardware state (MUX mode).
632 | - **Systemic Proof:** The issue is reproducible across different models and UEFI versions.

636 | Until a fix is implemented, millions of buyers of Asus laptops from approx. 2021 to present day are facing stutters on the simplest of tasks, such as watching YouTube, for the simple mistake of using a sleep call inside of an inefficient interrupt handler and not checking the GPU environment properly.
