This means # they can execute scv instructions after AIL is disabled, which causes an # interrupt at an unexpected entry location that crashes the kernel. # # Change the kexec sequence to disable AIL after other CPUs have been # brought down. # # As a refresher, the real-mode scv interrupt vector is 0x17000, and the # fixed-location head code probably couldn't easily deal with implementing # such high addresses so it was just decided not to support that interrupt # at all. # # Fixes: 7fa95f9adaee ("powerpc/64s: system call support for scv/rfscv instructions") # Cc: stable@vger.kernel.org # v5.9+ # Reported-by: Sourabh Jain <sourabhjain@linux.ibm.com> # Closes: https://lore.kernel.org/3b4b2943-49ad-4619-b195-bc416f1d1409@linux.ibm.com # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Tested-by: Gautam Menghani <gautam@linux.ibm.com> # Tested-by: Sourabh Jain <sourabhjain@linux.ibm.com> # Link: https://msgid.link/20240625134047.298759-1-npiggin@gmail.com # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 21a741eb75f80397e5f7d3739e24d7d75e619011 # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig Using /kisskb/src/arch/powerpc/configs/mpc85xx_base.config as base Merging /kisskb/src/arch/powerpc/configs/85xx-32bit.config Merging /kisskb/src/arch/powerpc/configs/85xx-hw.config Merging /kisskb/src/arch/powerpc/configs/fsl-emb-nonhw.config # # merged configuration written to .config (needs make) # # Added to kconfig CONFIG_PPC_E500MC=y # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM_E500MC=y # Added to kconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4597:warning: override: reassigning to symbol PPC_E500MC .config:4598:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/build_bug.h:5, from /kisskb/src/include/linux/container_of.h:5, from /kisskb/src/include/linux/list.h:5, from /kisskb/src/include/linux/module.h:12, from /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:15: /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c: In function 'allocate_bd': /kisskb/src/include/linux/err.h:28:49: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 28 \| #define IS_ERR_VALUE(x) unlikely((unsigned long)(void *)(x) >= (unsigned long)-MAX_ERRNO) \| ^ /kisskb/src/include/linux/compiler.h:77:45: note: in definition of macro 'unlikely' 77 \| # define unlikely(x) __builtin_expect(!!(x), 0) \| ^ /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:138:13: note: in expansion of macro 'IS_ERR_VALUE' 138 \| if (IS_ERR_VALUE(fep->ring_mem_addr)) \| ^~~~~~~~~~~~ /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8544ds.dtsi:154.11-204.6: Warning (interrupt_provider): /pcie@e000b000/pcie@0/uli1575@0/isa@1e: '#interrupt-cells' found, but node is not an interrupt provider arch/powerpc/boot/dts/fsl/mpc8544ds.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8572ds.dtsi:375.11-425.6: Warning (interrupt_provider): /pcie@ffe08000/pcie@0/uli1575@0/isa@1e: '#interrupt-cells' found, but node is not an interrupt provider arch/powerpc/boot/dts/fsl/mpc8572ds.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 # Build took: 0:01:53.643618
