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-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 d0cf9b561ca97d5245bb9e0c4774b7fadd897d67 # < make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_defconfig # Added to kconfig configs/2006/11/29/pmac32_defconfigkexec # yes \n | make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:25:0, from /kisskb/src/sound/ppc/awacs.c:29: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:220:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0); ^ /kisskb/src/sound/ppc/awacs.c:886:36: note: 'speaker_vol' was declared here struct snd_kcontrol *master_vol, *speaker_vol; ^ INFO: Uncompressed kernel (size 0x89c42c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) Completed OK # rm -rf /kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-5.3 # Build took: 0:02:50.626442
