[Kernel-packages] [Bug 1598529] Re: On update_blocked_averages function issue
Thank you for providing a patch, and making Ubuntu better. Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc? People affected by this bug are probably wondering why the kernel team doesn't just apply the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch to a stable kernel that is not from upstream. Applying patches that don't come from upstream add greatly to the support of the kernel as other upstream patches may touch the same area as the non-upstream patch and may prevent them from applying cleanly. To submit your patch, send your patch with the detailed description/changelog and your Signoff (ending with Signed-off-by: your name ), to the emails listed from ./scripts/get_maintainer.pl drivers/SUBSYSTEM-DETAILS (the get_maintainer.pl is from the kernel sources). Once you have sent the patch upstream and it's accepted, please drop a note here so that we can cherry-pick/include the patch into Ubuntu kernel. ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1598529 Title: On update_blocked_averages function issue Status in linux package in Ubuntu: Triaged Bug description: Bellow is result of perf report: .. │ cmp%rax,%r15 ▒ │ ↓ je 398 ▒ │ lea-0xd8(%rax),%rbx ▒ │ mov%r14,0x8(%rsp) ▒ │ movabs $0xafb504000afb5041,%r8 ▒ │ mov%r15,%r14 ▒ │ 71: nop ▒ │ mov0x124(%rbx),%r11d ▒ 26,56 │ test %r11d,%r11d ▒ │ ↓ jne426 ▒ │ 86: mov0xc8(%rbx),%rax ▒ 17,97 │ mov0x910(%rax),%rax ▒ 1,56 │ sub0x118(%rbx),%rax ▒ │ 9b: mov0xa0(%rbx),%rdx ▒ 12,50 │ xor%r15d,%r15d ▒ │ test %rdx,%rdx ▒ │ ↓ je ea ▒ │ xor%ecx,%ecx ▒ │ mov%rcx,%rdx ▒ │ xchg %rdx,0xa0(%rbx) ▒ │ sub%rdx,0x78(%rbx) ▒ │ mov%rcx,%rsi ▒ │ mov$0x1,%r15d ▒ │ cmpq $0x0,0x78(%rbx) .
