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-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 86de312343c4b56d699f8ed98aac8bdab1e94225 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_rainier_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/rainier_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_rainier_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x49d808) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.2.0-rc2-g86de312343c4 Created: Sun Jun 16 23:30:27 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2372879 Bytes = 2317.26 KiB = 2.26 MiB Load Address: 00500000 Entry Point: 00501534 Completed OK # rm -rf /kisskb/build/powerpc-next_44x_rainier_defconfig_powerpc-gcc5 # Build took: 0:00:37.245741
