E.g. upgrading from v5.4.93 to v5.4.100, Change "rpmversion" in SPECS/kernel-ampere-lts-5.4.spec is enough. 19 | 20 | To upgrade to a new PATCHLEVEL, you should copy a new spec file from the closest spec file. And change "rpmversion" and "kversion" in spec file. Besides this, the shebang patchfix list in spec file need to update as well. --------------------------------------------------------------------------------

By contrast, the GNU General Public 13 | License is intended to guarantee your freedom to share and change free 14 | software--to make sure the software is free for all its users. This 15 | General Public License applies to most of the Free Software 16 | Foundation's software and to any other program whose authors commit to 17 | using it. (Some other Free Software Foundation software is covered by 18 | the GNU Lesser General Public License instead.) You can apply it to 19 | your programs, too. 20 | 21 | When we speak of free software, we are referring to freedom, not 22 | price. Our General Public Licenses are designed to make sure that you 23 | have the freedom to distribute copies of free software (and charge for 24 | this service if you wish), that you receive source code or can get it 25 | if you want it, that you can change the software or use pieces of it 26 | in new free programs; and that you know you can do these things. 27 | 28 | To protect your rights, we need to make restrictions that forbid 29 | anyone to deny you these rights or to ask you to surrender the rights. 30 | These restrictions translate to certain responsibilities for you if you 31 | distribute copies of the software, or if you modify it. 32 | 33 | For example, if you distribute copies of such a program, whether 34 | gratis or for a fee, you must give the recipients all the rights that 35 | you have. You must make sure that they, too, receive or can get the 36 | source code. And you must show them these terms so they know their 37 | rights. 38 | 39 | We protect your rights with two steps: (1) copyright the software, and 40 | (2) offer you this license which gives you legal permission to copy, 41 | distribute and/or modify the software. 42 | 43 | Also, for each author's protection and ours, we want to make certain 44 | that everyone understands that there is no warranty for this free 45 | software. If the software is modified by someone else and passed on, we 46 | want its recipients to know that what they have is not the original, so 47 | that any problems introduced by others will not reflect on the original 48 | authors' reputations. 49 | 50 | Finally, any free program is threatened constantly by software 51 | patents. We wish to avoid the danger that redistributors of a free 52 | program will individually obtain patent licenses, in effect making the 53 | program proprietary. To prevent this, we have made it clear that any 54 | patent must be licensed for everyone's free use or not licensed at all. 55 | 56 | The precise terms and conditions for copying, distribution and 57 | modification follow. 58 | 59 | GNU GENERAL PUBLIC LICENSE 60 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61 | 62 | 0. This License applies to any program or other work which contains 63 | a notice placed by the copyright holder saying it may be distributed 64 | under the terms of this General Public License. The "Program", below, 65 | refers to any such program or work, and a "work based on the Program" 66 | means either the Program or any derivative work under copyright law: 67 | that is to say, a work containing the Program or a portion of it, 68 | either verbatim or with modifications and/or translated into another 69 | language. (Hereinafter, translation is included without limitation in 70 | the term "modification".) Each licensee is addressed as "you". 71 | 72 | Activities other than copying, distribution and modification are not 73 | covered by this License; they are outside its scope. The act of 74 | running the Program is not restricted, and the output from the Program 75 | is covered only if its contents constitute a work based on the 76 | Program (independent of having been made by running the Program). 77 | Whether that is true depends on what the Program does. 78 | 79 | 1. You may copy and distribute verbatim copies of the Program's 80 | source code as you receive it, in any medium, provided that you 81 | conspicuously and appropriately publish on each copy an appropriate 82 | copyright notice and disclaimer of warranty; keep intact all the 83 | notices that refer to this License and to the absence of any warranty; 84 | and give any other recipients of the Program a copy of this License 85 | along with the Program. 86 | 87 | You may charge a fee for the physical act of transferring a copy, and 88 | you may at your option offer warranty protection in exchange for a fee. 89 | 90 | 2. You may modify your copy or copies of the Program or any portion 91 | of it, thus forming a work based on the Program, and copy and 92 | distribute such modifications or work under the terms of Section 1 93 | above, provided that you also meet all of these conditions: 94 | 95 | a) You must cause the modified files to carry prominent notices 96 | stating that you changed the files and the date of any change. 97 | 98 | b) You must cause any work that you distribute or publish, that in 99 | whole or in part contains or is derived from the Program or any 100 | part thereof, to be licensed as a whole at no charge to all third 101 | parties under the terms of this License. 102 | 103 | c) If the modified program normally reads commands interactively 104 | when run, you must cause it, when started running for such 105 | interactive use in the most ordinary way, to print or display an 106 | announcement including an appropriate copyright notice and a 107 | notice that there is no warranty (or else, saying that you provide 108 | a warranty) and that users may redistribute the program under 109 | these conditions, and telling the user how to view a copy of this 110 | License. (Exception: if the Program itself is interactive but 111 | does not normally print such an announcement, your work based on 112 | the Program is not required to print an announcement.) 113 | 114 | These requirements apply to the modified work as a whole. If 115 | identifiable sections of that work are not derived from the Program, 116 | and can be reasonably considered independent and separate works in 117 | themselves, then this License, and its terms, do not apply to those 118 | sections when you distribute them as separate works. But when you 119 | distribute the same sections as part of a whole which is a work based 120 | on the Program, the distribution of the whole must be on the terms of 121 | this License, whose permissions for other licensees extend to the 122 | entire whole, and thus to each and every part regardless of who wrote it. 123 | 124 | Thus, it is not the intent of this section to claim rights or contest 125 | your rights to work written entirely by you; rather, the intent is to 126 | exercise the right to control the distribution of derivative or 127 | collective works based on the Program. 128 | 129 | In addition, mere aggregation of another work not based on the Program 130 | with the Program (or with a work based on the Program) on a volume of 131 | a storage or distribution medium does not bring the other work under 132 | the scope of this License. 133 | 134 | 3. You may copy and distribute the Program (or a work based on it, 135 | under Section 2) in object code or executable form under the terms of 136 | Sections 1 and 2 above provided that you also do one of the following: 137 | 138 | a) Accompany it with the complete corresponding machine-readable 139 | source code, which must be distributed under the terms of Sections 140 | 1 and 2 above on a medium customarily used for software interchange; or, 141 | 142 | b) Accompany it with a written offer, valid for at least three 143 | years, to give any third party, for a charge no more than your 144 | cost of physically performing source distribution, a complete 145 | machine-readable copy of the corresponding source code, to be 146 | distributed under the terms of Sections 1 and 2 above on a medium 147 | customarily used for software interchange; or, 148 | 149 | c) Accompany it with the information you received as to the offer 150 | to distribute corresponding source code. (This alternative is 151 | allowed only for noncommercial distribution and only if you 152 | received the program in object code or executable form with such 153 | an offer, in accord with Subsection b above.) 154 | 155 | The source code for a work means the preferred form of the work for 156 | making modifications to it. For an executable work, complete source 157 | code means all the source code for all modules it contains, plus any 158 | associated interface definition files, plus the scripts used to 159 | control compilation and installation of the executable. However, as a 160 | special exception, the source code distributed need not include 161 | anything that is normally distributed (in either source or binary 162 | form) with the major components (compiler, kernel, and so on) of the 163 | operating system on which the executable runs, unless that component 164 | itself accompanies the executable. 165 | 166 | If distribution of executable or object code is made by offering 167 | access to copy from a designated place, then offering equivalent 168 | access to copy the source code from the same place counts as 169 | distribution of the source code, even though third parties are not 170 | compelled to copy the source along with the object code. 171 | 172 | 4. You may not copy, modify, sublicense, or distribute the Program 173 | except as expressly provided under this License. Any attempt 174 | otherwise to copy, modify, sublicense or distribute the Program is 175 | void, and will automatically terminate your rights under this License. 176 | However, parties who have received copies, or rights, from you under 177 | this License will not have their licenses terminated so long as such 178 | parties remain in full compliance. 179 | 180 | 5. You are not required to accept this License, since you have not 181 | signed it. However, nothing else grants you permission to modify or 182 | distribute the Program or its derivative works. These actions are 183 | prohibited by law if you do not accept this License. Therefore, by 184 | modifying or distributing the Program (or any work based on the 185 | Program), you indicate your acceptance of this License to do so, and 186 | all its terms and conditions for copying, distributing or modifying 187 | the Program or works based on it. 188 | 189 | 6. Each time you redistribute the Program (or any work based on the 190 | Program), the recipient automatically receives a license from the 191 | original licensor to copy, distribute or modify the Program subject to 192 | these terms and conditions. You may not impose any further 193 | restrictions on the recipients' exercise of the rights granted herein. 194 | You are not responsible for enforcing compliance by third parties to 195 | this License. 196 | 197 | 7. If, as a consequence of a court judgment or allegation of patent 198 | infringement or for any other reason (not limited to patent issues), 199 | conditions are imposed on you (whether by court order, agreement or 200 | otherwise) that contradict the conditions of this License, they do not 201 | excuse you from the conditions of this License. If you cannot 202 | distribute so as to satisfy simultaneously your obligations under this 203 | License and any other pertinent obligations, then as a consequence you 204 | may not distribute the Program at all. For example, if a patent 205 | license would not permit royalty-free redistribution of the Program by 206 | all those who receive copies directly or indirectly through you, then 207 | the only way you could satisfy both it and this License would be to 208 | refrain entirely from distribution of the Program. 209 | 210 | If any portion of this section is held invalid or unenforceable under 211 | any particular circumstance, the balance of the section is intended to 212 | apply and the section as a whole is intended to apply in other 213 | circumstances. 214 | 215 | It is not the purpose of this section to induce you to infringe any 216 | patents or other property right claims or to contest validity of any 217 | such claims; this section has the sole purpose of protecting the 218 | integrity of the free software distribution system, which is 219 | implemented by public license practices. Many people have made 220 | generous contributions to the wide range of software distributed 221 | through that system in reliance on consistent application of that 222 | system; it is up to the author/donor to decide if he or she is willing 223 | to distribute software through any other system and a licensee cannot 224 | impose that choice. 225 | 226 | This section is intended to make thoroughly clear what is believed to 227 | be a consequence of the rest of this License. 228 | 229 | 8. If the distribution and/or use of the Program is restricted in 230 | certain countries either by patents or by copyrighted interfaces, the 231 | original copyright holder who places the Program under this License 232 | may add an explicit geographical distribution limitation excluding 233 | those countries, so that distribution is permitted only in or among 234 | countries not thus excluded. In such case, this License incorporates 235 | the limitation as if written in the body of this License. 236 | 237 | 9. The Free Software Foundation may publish revised and/or new versions 238 | of the General Public License from time to time. Such new versions will 239 | be similar in spirit to the present version, but may differ in detail to 240 | address new problems or concerns. 241 | 242 | Each version is given a distinguishing version number. If the Program 243 | specifies a version number of this License which applies to it and "any 244 | later version", you have the option of following the terms and conditions 245 | either of that version or of any later version published by the Free 246 | Software Foundation. If the Program does not specify a version number of 247 | this License, you may choose any version ever published by the Free Software 248 | Foundation. 249 | 250 | 10. If you wish to incorporate parts of the Program into other free 251 | programs whose distribution conditions are different, write to the author 252 | to ask for permission. For software which is copyrighted by the Free 253 | Software Foundation, write to the Free Software Foundation; we sometimes 254 | make exceptions for this. Our decision will be guided by the two goals 255 | of preserving the free status of all derivatives of our free software and 256 | of promoting the sharing and reuse of software generally. 257 | 258 | NO WARRANTY 259 | 260 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

117 | mdelay(latency); 118 | local_irq_enable(); 119 | } 120 | ``` 121 | 122 | 通过模块测试以上代码，然后查看栈信息。 123 | 124 | ```bash 125 | cat /proc/trace_irqoff/trace_latency 126 | trace_irqoff_latency: 50ms 127 | hardirq: 128 | cpu: 17 129 | COMMAND: bash PID: 22840 LATENCY: 107ms 130 | trace_irqoff_hrtimer_handler+0x39/0x99 [trace_irqoff] 131 | __hrtimer_run_queues+0xfa/0x270 132 | hrtimer_interrupt+0x101/0x240 133 | smp_apic_timer_interrupt+0x5e/0x120 134 | apic_timer_interrupt+0xf/0x20 135 | disable_hardirq+0x5b/0x70 136 | proc_reg_write+0x36/0x60 137 | __vfs_write+0x33/0x190 138 | vfs_write+0xb0/0x190 139 | ksys_write+0x52/0xc0 140 | do_syscall_64+0x4f/0xe0 141 | entry_SYSCALL_64_after_hwframe+0x44/0xa9 142 | softirq: 143 | ``` 144 | 145 | 我们可以看到 hardirq 一栏记录 cpu17 执行 bash 命令，关闭中断 107ms（误差 10ms 之内）。其栈信息对应disable_hardirq() 函数中。第 20 行 softirq 一栏没有信息，说明没有记录 softirq 被关闭的栈。 146 | 147 | ##### 2. softirq 关闭 148 | 149 | 我们使用如下示意测试程序，关闭 softirq 100ms。查看 trace_irqoff 文件内容。 150 | 151 | ```c 152 | static void disable_softirq(unsigned long latency) 153 | { 154 | local_bh_disable(); 155 | mdelay(latency); 156 | local_bh_enable(); 157 | } 158 | ``` 159 | 160 | 通过模块测试以上代码，然后查看栈信息。 161 | 162 | ```bash 163 | cat /proc/trace_irqoff/trace_latency 164 | trace_irqoff_latency: 50ms 165 | hardirq: 166 | softirq: 167 | cpu: 17 168 | COMMAND: bash PID: 22840 LATENCY: 51+ms 169 | trace_irqoff_hrtimer_handler+0x97/0x99 [trace_irqoff] 170 | __hrtimer_run_queues+0xfa/0x270 171 | hrtimer_interrupt+0x101/0x240 172 | smp_apic_timer_interrupt+0x5e/0x120 173 | apic_timer_interrupt+0xf/0x20 174 | delay_tsc+0x3c/0x50 175 | disable_softirq+0x4b/0x80 176 | proc_reg_write+0x36/0x60 177 | __vfs_write+0x33/0x190 178 | vfs_write+0xb0/0x190 179 | ksys_write+0x52/0xc0 180 | do_syscall_64+0x4f/0xe0 181 | entry_SYSCALL_64_after_hwframe+0x44/0xa9 182 | 183 | COMMAND: bash PID: 22840 LATENCY: 106ms 184 | trace_irqoff_timer_handler+0x3a/0x60 [trace_irqoff] 185 | call_timer_fn+0x29/0x120 186 | run_timer_softirq+0x16c/0x400 187 | __do_softirq+0x108/0x2b8 188 | do_softirq_own_stack+0x2a/0x40 189 | do_softirq.part.21+0x56/0x60 190 | __local_bh_enable_ip+0x60/0x70 191 | disable_softirq+0x62/0x80 192 | proc_reg_write+0x36/0x60 193 | __vfs_write+0x33/0x190 194 | vfs_write+0xb0/0x190 195 | ksys_write+0x52/0xc0 196 | do_syscall_64+0x4f/0xe0 197 | entry_SYSCALL_64_after_hwframe+0x44/0xa9 198 | ``` 199 | 200 | 针对 softirq 关闭情况，有 2 个栈与之对应。我们注意到第 9 行的函数名称和第 24 行的函数名称是不一样的。第 9 行的栈是硬件中断 handler 捕捉到软中断关闭，第 24 行是软中断 handler 捕捉到软中断被关闭。正常情况下，我们以 24 行开始的栈为分析目标即可。当 24 行的栈是无效的时候，可以看第 9 行的栈。这里注意：第 9 行的 lantency 提示信息 **51+ms** 是阈值信息。并非实际 latency（所以我在后面添加一个'+'字符，表示latency大于51ms）。实际的 latency 是第 24 行显示的 106ms。下面就看下为什么 2 个栈是有必要的。 201 | 202 | ##### 3. ksoftirqd 延迟 203 | 204 | 我们看一个曾经处理的一个实际问题。 205 | 206 | ```bash 207 | cat /proc/trace_irqoff/trace_latency 208 | trace_irqoff_latency: 300ms 209 | hardirq: 210 | softirq: 211 | cpu: 4 212 | COMMAND: lxcfs PID: 4058797 LATENCY: 303+ms 213 | trace_irqoff_record+0x12b/0x1b0 [trace_irqoff] 214 | trace_irqoff_hrtimer_handler+0x97/0x99 [trace_irqoff] 215 | __hrtimer_run_queues+0xdc/0x220 216 | hrtimer_interrupt+0xa6/0x1f0 217 | smp_apic_timer_interrupt+0x62/0x120 218 | apic_timer_interrupt+0x7d/0x90 219 | memcg_sum_events.isra.26+0x3f/0x60 220 | memcg_stat_show+0x323/0x460 221 | seq_read+0x11f/0x3f0 222 | __vfs_read+0x33/0x160 223 | vfs_read+0x91/0x130 224 | SyS_read+0x52/0xc0 225 | do_syscall_64+0x68/0x100 226 | entry_SYSCALL_64_after_hwframe+0x3d/0xa2 227 | 228 | COMMAND: ksoftirqd/4 PID: 34 LATENCY: 409ms 229 | trace_irqoff_record+0x12b/0x1b0 [trace_irqoff] 230 | trace_irqoff_timer_handler+0x3a/0x60 [trace_irqoff] 231 | call_timer_fn+0x2e/0x130 232 | run_timer_softirq+0x1d4/0x420 233 | __do_softirq+0x108/0x2a9 234 | run_ksoftirqd+0x1e/0x40 235 | smpboot_thread_fn+0xfe/0x150 236 | kthread+0xfc/0x130 237 | ret_from_fork+0x1f/0x30 238 | ``` 239 | 240 | 我们看到下面的进程 ksoftirqd/4 的栈，延迟时间是 409ms。ksoftirqd 进程是 kernel 中处理 softirq 的进程。因此这段栈对我们是没有意义的，因为元凶已经错过了。所以此时，我们可以借鉴上面的栈信息，我们看到当 softirq 被延迟 303ms 的时候，当前 CPU 正在执行的进程是 lxcfs。并且栈是 memory cgroup 相关。因此，我们基本可以判断 lxcfs 进程执行时间过长，由于 kernel 态不支持抢占，因此导致 ksoftirqd 进程没有机会得到运行。 241 | 242 | -------------------------------------------------------------------------------- /tools/trace-irqoff/readme.txt: -------------------------------------------------------------------------------- 1 | cd tools/trace-irqoff/ 2 | make 3 | sudo make install 4 | 5 | cd /proc/trade-irqoff 6 | ls 7 | distribute enable sampling_period trace_latency 8 | 9 | I used mdelay in the code to simulate IRQ timeout. 10 | 11 | --- a/trace_irqoff.c 12 | +++ b/trace_irqoff.c 13 | @@ -700,10 +700,18 @@ static const struct proc_ops enable_fops = { 14 | .proc_release = single_release, 15 | };
