However the calculation used to determine if two VSRs # needed to be loaded/stored inadvertently prevented the load/storing # taking place for instructions with a data length less than 16 words. # # This causes the emulation to not function correctly, which can be seen # by the alignment_handler selftest: # # $ ./alignment_handler # [snip] # test: test_alignment_handler_vsx_207 # tags: git_version:powerpc-5.12-1-0-g82d2c16b350f # VSX: 2.07B # Doing lxsspx: PASSED # Doing lxsiwax: FAILED: Wrong Data # Doing lxsiwzx: PASSED # Doing stxsspx: PASSED # Doing stxsiwx: PASSED # failure: test_alignment_handler_vsx_207 # test: test_alignment_handler_vsx_300 # tags: git_version:powerpc-5.12-1-0-g82d2c16b350f # VSX: 3.00B # Doing lxsd: PASSED # Doing lxsibzx: PASSED # Doing lxsihzx: PASSED # Doing lxssp: FAILED: Wrong Data # Doing lxv: PASSED # Doing lxvb16x: PASSED # Doing lxvh8x: PASSED # Doing lxvx: PASSED # Doing lxvwsx: FAILED: Wrong Data # Doing lxvl: PASSED # Doing lxvll: PASSED # Doing stxsd: PASSED # Doing stxsibx: PASSED # Doing stxsihx: PASSED # Doing stxssp: PASSED # Doing stxv: PASSED # Doing stxvb16x: PASSED # Doing stxvh8x: PASSED # Doing stxvx: PASSED # Doing stxvl: PASSED # Doing stxvll: PASSED # failure: test_alignment_handler_vsx_300 # [snip] # # Fix this by making sure all VSX instruction emulation correctly # load/store from the VSRs. # # Fixes: af99da74333b ("powerpc/sstep: Support VSX vector paired storage access instructions") # Signed-off-by: Jordan Niethe <jniethe5@gmail.com> # Reviewed-by: Ravi Bangoria <ravi.bangoria@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20210225031946.1458206-1-jniethe5@gmail.com # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e3d773ddb5a1140780a15703b3e0e2618274cce9 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_MEMORY_HOTREMOVE_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig # Added to kconfig CONFIG_MEMORY_HOTPLUG=y # Added to kconfig CONFIG_MEMORY_HOTREMOVE=n # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_MEMORY_HOTREMOVE_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_MEMORY_HOTREMOVE_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+NO_MEMORY_HOTREMOVE_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c: In function 'cxgb4_write_partial_sgl': /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c:910:9: warning: missing braces around initializer [-Wmissing-braces] struct ulptx_sge_pair buf[MAX_SKB_FRAGS / 2 + 1] = {0}, *to; ^ /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c:910:9: warning: (near initialization for 'buf[0]') [-Wmissing-braces] /kisskb/src/fs/btrfs/tree-checker.c: In function 'check_root_item': /kisskb/src/fs/btrfs/tree-checker.c:1071:9: warning: missing braces around initializer [-Wmissing-braces] struct btrfs_root_item ri = { 0 }; ^ /kisskb/src/fs/btrfs/tree-checker.c:1071:9: warning: (near initialization for 'ri.inode') [-Wmissing-braces] Completed OK # rm -rf /kisskb/build/powerpc-fixes_pseries_defconfig+NO_MEMORY_HOTREMOVE_powerpc-gcc4.9 # Build took: 0:03:02.291937
