If it # is determined that the delta can not be calculated, it falls back to # adding an absolute timestamp value. The way to know if the delta can # be used is via two stored timestamps in the per-cpu buffer meta data: # # before_stamp and write_stamp # # The before_stamp is written by every event before it tries to allocate # its space on the ring buffer. The write_stamp is written after it # allocates its space and knows that nothing came in after it read the # previous before_stamp and write_stamp and the two matched. # # A previous fix dd9394257078 ("ring-buffer: Do not try to put back # write_stamp") removed putting back the write_stamp to match the # before_stamp so that the next event could use the delta, but races # were found where the two would match, but not be for of the previous # event. # # It was determined to allow the event reservation to not have a valid # write_stamp when it is finished, and this fixed a lot of races. # # The last use of the 64-bit timestamp cmpxchg depended on the # write_stamp being valid after an interruption. But this is no longer # the case, as if an event is interrupted by a softirq that writes an # event, and that event gets interrupted by a hardirq or NMI and that # writes an event, then the softirq could finish its reservation without # a valid write_stamp. # # In the slow path of the event reservation, a delta can still be used # if the write_stamp is valid. Instead of using a cmpxchg against the # write stamp, the before_stamp needs to be read again to validate the # write_stamp. The cmpxchg is not needed. # # This updates the slowpath to validate the write_stamp by comparing it # to the before_stamp and removes all rb_time_cmpxchg() as there are no # more users of that function. # # The removal of the 32-bit updates of rb_time_t will be done in the # next merge window" # # * tag 'trace-v6.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: # ring-buffer: Fix slowpath of interrupted event # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 55cb5f43689d7a9ea5bf35ef050f12334f197347 # make -s -j 160 ARCH=mips O=/kisskb/build/linus_micro32r2el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- micro32r2el_defconfig Using /kisskb/src/arch/mips/configs/generic_defconfig as base Merging /kisskb/src/arch/mips/configs/generic/micro32r2.config Merging /kisskb/src/arch/mips/configs/generic/el.config Merging /kisskb/src/arch/mips/configs/generic/board-boston.config Merging /kisskb/src/arch/mips/configs/generic/board-marduk.config Merging /kisskb/src/arch/mips/configs/generic/board-ni169445.config Merging /kisskb/src/arch/mips/configs/generic/board-ocelot.config Merging /kisskb/src/arch/mips/configs/generic/board-ranchu.config Merging /kisskb/src/arch/mips/configs/generic/board-sead-3.config Merging /kisskb/src/arch/mips/configs/generic/board-virt.config Merging /kisskb/src/arch/mips/configs/generic/board-xilfpga.config # < make -s -j 160 ARCH=mips O=/kisskb/build/linus_micro32r2el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 160 ARCH=mips O=/kisskb/build/linus_micro32r2el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 160 ARCH=mips O=/kisskb/build/linus_micro32r2el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- {standard input}: Assembler messages: {standard input}:5030: Error: branch to a symbol in another ISA mode make[5]: * [/kisskb/src/scripts/Makefile.build:243: arch/mips/kernel/smp-cps.o] Error 1 make[5]: * Waiting for unfinished jobs.... make[4]: * [/kisskb/src/scripts/Makefile.build:480: arch/mips/kernel] Error 2 make[3]: * [/kisskb/src/scripts/Makefile.build:480: arch/mips] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/Makefile:1911: .] Error 2 make[1]: * [/kisskb/src/Makefile:234: __sub-make] Error 2 make: * [Makefile:234: __sub-make] Error 2 Command 'make -s -j 160 ARCH=mips O=/kisskb/build/linus_micro32r2el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_micro32r2el_defconfig_mips-gcc12 # Build took: 0:01:31.886754
