ESL=1 # sleeps that do not lose GPRs can use this optimization too. # # - KVM secondary entry and cede is now more of a call/return style # rather than branchy. nap_state_lost is not required because KVM # always returns via NVGPR restoring path. # # Reviewed-by: Gautham R. Shenoy <ego@linux.vnet.ibm.com> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # # Left to do: # - KVM could use more review, it's pretty tricky. Not sure if what # I'm doing with the emergency stack is kosher. But it runs pretty fine # here with a POWER8 SMP+SMT guest. Possible to streamline # KVM cede code now that idle function saves nv gprs for us? # # Open question: # - Why does P9 restore some of the PMU SPRs (but not others), and # P8 only zeroes them? (A: Unclear. First pass conversion patch will not # try to tidy this up, but it will become much easier to do afterward). # # Since RFC v1: # - Now tested and working with POWER9 hash and radix. # - KVM support added. This took a bit of work to untangle and might # still have some issues, but POWER9 seems to work including hash on # radix with dependent threads mode. # - This snowballed a bit because of KVM and other details making it # not feasible to leave POWER7/8 code alone. That's only half done # at the moment. # - So far this trades about 800 lines of asm for 500 of C. With POWER7/8 # support done it might be another hundred or so lines of C. # # Since RFC v2: # - Fixed deep state SLB reloading # - Now tested and working with POWER8. # - Accounted for most feedback. # # Since RFC v3: # - Rebased to powerpc merge + idle state bugfix # - Split SLB flush/restore code out and shared with MCE code (pseries # MCE patches can also use). # - More testing on POWER8 including KVM with secondaries. # - Performance testing looks good. EC=ESL=0 is about 5% faster, other # stop states look a little faster too. # - Adjusted SPR saving to handler POWER7, haven't tested it. # # Since submission v1: # - More review comments from Gautham. # - Rename isa3_ to isa300_ prefix. # - Tinkered with some comments, copyright notice, changelog. # - Cede and regular idle do not go via KVM secondary wakeup code path, # so hwthread_state stores and barriers can be simplified, and some # KVM code paths simplified a little. # # Since v2: # - Rebase, SLB reload patch has been merged. # - More testing. Tested machine check idle wakeup path with mambo stepping # through instructions. # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 d899987759d5c18c26204a3defc15a3fb55048c0 # < make -s -j 48 ARCH=x86 O=/kisskb/build/npiggin_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- x86_64_defconfig # make -s -j 48 ARCH=x86 O=/kisskb/build/npiggin_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- In file included from /kisskb/src/include/trace/define_trace.h:97, from /kisskb/src/include/trace/events/writeback.h:762, from /kisskb/src/fs/fs-writeback.c:98: /kisskb/src/include/trace/events/writeback.h: In function 'perf_trace_writeback_work_class': /kisskb/src/include/trace/events/writeback.h:223:3: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation] strncpy(__entry->name, ^~~~~~~~~~~~~~~~~~~~~~ wb->bdi->dev ? dev_name(wb->bdi->dev) : "(unknown)", 32);
