The difference is WRT how we handle hash # fault on these address. THP address enables MPSS in segments. We want # to manage devmap hugepage entries similar to THP pt entries. Hence use # H_PAGE_THP_HUGE for devmap huge PTE entries. # # With current code while handling hash PTE fault, we do set is_thp = # true when finding devmap PTE huge PTE entries. # # Current code also does the below sequence we setting up huge devmap # entries. # # entry = pmd_mkhuge(pfn_t_pmd(pfn, prot)); # if (pfn_t_devmap(pfn)) # entry = pmd_mkdevmap(entry); # # In that case we would find both H_PAGE_THP_HUGE and PAGE_DEVMAP set # for huge devmap PTE entries. This results in false positive error like # below. # # kernel BUG at /home/kvaneesh/src/linux/mm/memory.c:4321! # Oops: Exception in kernel mode, sig: 5 [#1] # LE PAGE_SIZE=64K MMU=Hash SMP NR_CPUS=2048 NUMA pSeries # Modules linked in: # CPU: 56 PID: 67996 Comm: t_mmap_dio Not tainted 5.6.0-rc4-59640-g371c804dedbc #128 # .... # NIP [c00000000044c9e4] __follow_pte_pmd+0x264/0x900 # LR [c0000000005d45f8] dax_writeback_one+0x1a8/0x740 # Call Trace: # str_spec.74809+0x22ffb4/0x2d116c (unreliable) # dax_writeback_one+0x1a8/0x740 # dax_writeback_mapping_range+0x26c/0x700 # ext4_dax_writepages+0x150/0x5a0 # do_writepages+0x68/0x180 # __filemap_fdatawrite_range+0x138/0x180 # file_write_and_wait_range+0xa4/0x110 # ext4_sync_file+0x370/0x6e0 # vfs_fsync_range+0x70/0xf0 # sys_msync+0x220/0x2e0 # system_call+0x5c/0x68 # # This is because our pmd_trans_huge check doesn't exclude _PAGE_DEVMAP. # # To make this all consistent, update pmd_mkdevmap to set # H_PAGE_THP_HUGE and pmd_trans_huge check now excludes _PAGE_DEVMAP # correctly. # # Fixes: ebd31197931d ("powerpc/mm: Add devmap support for ppc64") # Cc: stable@vger.kernel.org # v4.13+ # Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200313094842.351830-1-aneesh.kumar@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 ba25b5ebe96a63940a12d9f8d73edebfcaad470c # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0xC888246C # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=n # Added to kconfig CONFIG_CPU_LITTLE_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_BOOK3E_64=n # Added to kconfig CONFIG_PPC_BOOK3S_64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4022:warning: override: reassigning to symbol PPC_BOOK3S_64 .config:4024:warning: override: reassigning to symbol SECTION_MISMATCH_WARN_ONLY .config:4025:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:4027:warning: override: reassigning to symbol TRIM_UNUSED_KSYMS .config:4028:warning: override: reassigning to symbol UBSAN WARNING: unmet direct dependencies detected for HOTPLUG_PCI_POWERNV Depends on [n]: PCI [=y] && HOTPLUG_PCI [=n] && PPC_POWERNV [=y] && EEH [=y] Selected by [m]: -
