From: David Daney <[email protected]> This patch set (or something like it) is needed for the Cavium ThunderX, but its performance improvements may make it compelling on its own merits.
Summery: On ThunerX we cannot use broadcast TLB invalidation, so we use IPIs where necessary. The funny thing is that it also happens to make workloads similar to kernel builds much faster. David Daney (3): arm64, mm: Add flush_tlb_all_local() function. arm64, mm: Use flush_tlb_all_local() in flush_context(). arm64, mm: Use IPIs for TLB invalidation. arch/arm64/include/asm/tlbflush.h | 64 ++++++++------------------------------- arch/arm64/mm/context.c | 2 +- arch/arm64/mm/flush.c | 46 ++++++++++++++++++++++++++++ 3 files changed, 59 insertions(+), 53 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
