Hi, The first part of this series up to patch 5 includes MCE handler definitions for POWER9. Probably the biggest concern is the new MCE types and how they are recorded and reported, so comments on that would be welcome.
Patches 6 onward change the MCE parsing into a table base approach. Note, those later changes are not functionally identical (as noted in comments, e.g. effective address and ERAT flushing changes slightly). This has had some testing with a userspace harness, as well as some tests in mambo. Thanks, Nick Nicholas Piggin (9): powerpc/64s: machine check print NIP powerpc/64s: allow machine check handler to set severity and initiator powerpc/64s: clean up machine check recovery flushing powerpc/64s: cope with non-synchronous machine checks powerpc/64s: POWER9 machine check handler powerpc/64s: move POWER machine check defines into mce_power.c powerpc/64s: data driven machine check evaluation powerpc/64s: data driven machine check handling powerpc/64s: POWER8 add missing machine check definitions arch/powerpc/include/asm/bitops.h | 4 + arch/powerpc/include/asm/mce.h | 101 +++--- arch/powerpc/kernel/cputable.c | 3 + arch/powerpc/kernel/mce.c | 91 +++++- arch/powerpc/kernel/mce_power.c | 590 +++++++++++++++++++++++----------- arch/powerpc/platforms/powernv/opal.c | 20 +- 6 files changed, 564 insertions(+), 245 deletions(-) -- 2.11.0
