------- Comment From [email protected] 2019-04-29 17:43 EDT------- I did some more testing, including toggling /sys/kernel/debug/powerpc/count_cache_flush and checking the code in xmon before: c00000000000db58 7ee00026 mfcr r23 c00000000000db5c fae101a0 std r23,416(r1) c00000000000db60 f8230000 std r1,0(r3) c00000000000db64 4bffdb1d bl c00000000000b680 # flush_count_cache+0x0/0x2480
and after: c00000000000db58 7ee00026 mfcr r23 c00000000000db5c fae101a0 std r23,416(r1) c00000000000db60 f8230000 std r1,0(r3) c00000000000db64 60000000 nop All looks correct. Thanks for flipping the tag, I think it looks good. I'll run some regression on it now, too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822870 Title: Backport support for software count cache flush Spectre v2 mitigation.
