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/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 86de312343c4b56d699f8ed98aac8bdab1e94225 # < make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-next_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-next_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-next_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/fs/btrfs/props.c: In function 'inherit_props': /kisskb/src/fs/btrfs/props.c:389:4: warning: 'num_bytes' may be used uninitialized in this function [-Wmaybe-uninitialized] btrfs_block_rsv_release(fs_info, trans->block_rsv, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ num_bytes); ~~~~~~~~~~ warning: same module names found: drivers/regulator/88pm800.ko drivers/mfd/88pm800.ko warning: same module names found: drivers/gpu/drm/bridge/adv7511/adv7511.ko drivers/media/i2c/adv7511.ko warning: same module names found: drivers/net/phy/asix.ko drivers/net/usb/asix.ko warning: same module names found: fs/coda/coda.ko drivers/media/platform/coda/coda.ko warning: same module names found: drivers/net/phy/realtek.ko drivers/net/dsa/realtek.ko Completed OK # rm -rf /kisskb/build/powerpc-next_x86-allmodconfig_x86_64-gcc8 # Build took: 0:21:51.549706
