I don't have a # benchmark for this change, but huge vmap will be used by a later core # kernel change to enable huge vmalloc memory mappings. This improves # cached `git diff` performance by about 5% on a 2-node POWER9 with 32MB # size dentry cache hash. # # Profiling git diff dTLB misses with a vanilla kernel: # # 81.75% git [kernel.vmlinux] [k] __d_lookup_rcu # 7.21% git [kernel.vmlinux] [k] strncpy_from_user # 1.77% git [kernel.vmlinux] [k] find_get_entry # 1.59% git [kernel.vmlinux] [k] kmem_cache_free # # 40,168 dTLB-miss # 0.100342754 seconds time elapsed # # With powerpc huge vmalloc: # # 2,987 dTLB-miss # 0.095933138 seconds time elapsed # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux-ld --version # < git log --format=%s --max-count=1 d909f9109c301f4e9e41678025c45d719ab8f7d7 # < make -s -j 80 ARCH=parisc O=/kisskb/build/powerpc-next_parisc-defconfig_parisc CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- defconfig # make -s -j 80 ARCH=parisc O=/kisskb/build/powerpc-next_parisc-defconfig_parisc CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- In file included from /kisskb/src/arch/parisc/math-emu/fcnvxf.c:51: /kisskb/src/arch/parisc/math-emu/fcnvxf.c: In function 'sgl_to_sgl_fcnvxf': /kisskb/src/arch/parisc/math-emu/cnv_float.h:63:52: warning: '<<' in boolean context, did you mean '<' ?
