[hugetlbfs] 9c83282117: vm-scalability.throughput -4.3% regression

by kernel test robot

Greeting, FYI, we noticed a -4.3% regression of vm-scalability.throughput due to commit: commit: 9c83282117778856d647ffc461c4aede2abb6742 ("[PATCH v3 1/2] hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization") url: https://github.com/0day-ci/linux/commits/Mike-Kravetz/hugetlbfs-use-i_mma... in testcase: vm-scalability on test machine: 104 threads Intel(R) Xeon(R) Platinum 8170 CPU @ 2.10GHz with 64G memory with following parameters: runtime: 300s size: 8T test: anon-cow-seq-hugetlb cpufreq_governor: performance ucode: 0x200004d test-description: The motivation behind this suite

4768ab44d7 [ 1.793066] WARNING: CPU: 0 PID: 0 at kernel/locking/lockdep.c:2803 lockdep_hardirqs_on

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://github.com/0day-ci/linux/commits/Uros-Bizjak/x86-asm-Use-CC_SET-C... commit 4768ab44d72e992a1f00ecca2f48e2137b3e90d0 Author: Uros Bizjak <ubizjak(a)gmail.com> AuthorDate: Fri Dec 28 16:37:59 2018 +0100 Commit: 0day robot <lkp(a)intel.com> CommitDate: Sat Dec 29 00:53:11 2018 +0800 x86/asm: Use CC_SET/CC_OUT in percpu_cmpxchg16b_double Use CC_SET(z)/CC_OUT(z) instead of explicit setz instruction. Using these two defines, the compiler that supports generation of condition code outputs from inline assembly flags generates one conditional jump instruction, e.g: [lea (%rdi),%rsi callq this_cpu_cmpxchg16b_emu] -- or -- [cmpxchg16b %gs:(%rdi)] jne 199764 <kmem_cache_alloc+0x44> instead of [lea (%rdi),%rsi callq this_cpu_cmpxchg16b_emu] -- or -- [cmpxchg16b %gs:(%rdi)] sete %cl test %cl,%cl je 19ae04 <kmem_cache_alloc+0x44> The complication with percpu_cmpxchg16b_double is, that the definition defaults to the call to this_cpu_cmpxchg16b_emu library function, which (depending on X86_FEATURE_CX16 flag) is later patched with real cmpxchg16b instruction. To solve this complication, the patch changes this_cpu_cmpxchg16b_emu library function to return the result in ZF flag of %rflags register, instead of %al register. Please also note that instead of popf instruction (which restores flags register to a previously saved state), the patched function uses sti, but followed by a nop, which ends the inhibition of interrupts early. The patch also introduces alternative_io_tail definition. This definition can take a tail instruction, common to all alternatives. By using this definition, it is possible to remove setz from cmpxchg16b alternatives, saved in .altinstr_replacement section, thus saving a few bytes from the binary.

Greeting, FYI, we noticed a -38.0% regression of fsmark.files_per_sec due to commit: commit: fde872682e175743e0c3ef939c89e3c6008a1529 ("ext4: force inode writes when nfsd calls commit_metadata()")
