This can # result in contention of ATSD registers leading to soft lockups on some # threads, particularly when invalidating a large address range in # pnv_npu2_mn_invalidate_range(). # # At some threshold it becomes more efficient to flush the entire GPU # TLB for the given MM context (PID) than individually flushing each # address in the range. This patch will result in ranges greater than # 2MB being converted from 32+ ATSDs into a single ATSD which will flush # the TLB for the given PID on each GPU. # # Fixes: 1ab66d1fbada ("powerpc/powernv: Introduce address translation services for Nvlink2") # Cc: stable@vger.kernel.org # v4.12+ # Signed-off-by: Alistair Popple <alistair@popple.id.au> # Acked-by: Balbir Singh <bsingharora@gmail.com> # Tested-by: Balbir Singh <bsingharora@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 1e072bee33d09c62a975faab919a5be92d9538ab # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_c2k_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- c2k_defconfig WARNING: unmet direct dependencies detected for NOT_COHERENT_CACHE Depends on [n]: 4xx [=n] \|\| PPC_8xx [=n] \|\| E200 [=n] \|\| PPC_MPC512x [=n] \|\| GAMECUBE_COMMON [=n] Selected by [y]: - PPC_C2K [=y] && EMBEDDED6xx [=y] WARNING: unmet direct dependencies detected for NOT_COHERENT_CACHE Depends on [n]: 4xx [=n] \|\| PPC_8xx [=n] \|\| E200 [=n] \|\| PPC_MPC512x [=n] \|\| GAMECUBE_COMMON [=n] Selected by [y]: - PPC_C2K [=y] && EMBEDDED6xx [=y] # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_c2k_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- WARNING: unmet direct dependencies detected for NOT_COHERENT_CACHE Depends on [n]: 4xx [=n] \|\| PPC_8xx [=n] \|\| E200 [=n] \|\| PPC_MPC512x [=n] \|\| GAMECUBE_COMMON [=n] Selected by [y]: - PPC_C2K [=y] && EMBEDDED6xx [=y] WARNING: unmet direct dependencies detected for NOT_COHERENT_CACHE Depends on [n]: 4xx [=n] \|\| PPC_8xx [=n] \|\| E200 [=n] \|\| PPC_MPC512x [=n] \|\| GAMECUBE_COMMON [=n] Selected by [y]: - PPC_C2K [=y] && EMBEDDED6xx [=y] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2497:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1819:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/bridge/br_netlink.c: In function 'br_afspec': /kisskb/src/net/bridge/br_netlink.c:635:7: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:340:21: note: 'pdeo' was declared here /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1827:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1737:46: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x6b9eac) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-4.17.0-rc1-g1e072be Created: Fri Apr 20 23:59:15 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3251597 Bytes = 3175.39 kB = 3.10 MB Load Address: 00700000 Entry Point: 007004fc Completed OK # rm -rf /kisskb/build/powerpc-fixes_c2k_defconfig_powerpc # Build took: 0:01:25.625184
