[PATCH 00/18] drivers: Remove oprofile and dcookies
|
From: Viresh K. <vir...@li...> - 2021-01-14 11:59:12
|
Hello, The "oprofile" user-space tools don't use the kernel OPROFILE support any more, and haven't in a long time. User-space has been converted to the perf interfaces. Remove oprofile and dcookies (whose only user is oprofile) support from the kernel. This was suggested here [1] earlier. This is build/boot tested by kernel test robot (Intel) and Linaro's Tuxmake[2] for a lot of architectures and no failures were reported. -- Viresh [1] https://lore.kernel.org/lkml/CAHk-=whw...@ma.../ [2] https://lwn.net/Articles/841624/ Viresh Kumar (18): arch: alpha: Remove CONFIG_OPROFILE support arch: arm: Remove CONFIG_OPROFILE support arch: arc: Remove CONFIG_OPROFILE support arch: hexagon: Don't select HAVE_OPROFILE arch: ia64: Remove CONFIG_OPROFILE support arch: ia64: Remove rest of perfmon support arch: microblaze: Remove CONFIG_OPROFILE support arch: mips: Remove CONFIG_OPROFILE support arch: parisc: Remove CONFIG_OPROFILE support arch: powerpc: Stop building and using oprofile arch: powerpc: Remove oprofile arch: s390: Remove CONFIG_OPROFILE support arch: sh: Remove CONFIG_OPROFILE support arch: sparc: Remove CONFIG_OPROFILE support arch: x86: Remove CONFIG_OPROFILE support arch: xtensa: Remove CONFIG_OPROFILE support drivers: Remove CONFIG_OPROFILE support fs: Remove dcookies support Documentation/RCU/NMI-RCU.rst | 3 +- .../admin-guide/kernel-parameters.txt | 14 -
