If that happens, the linux code # confusingly treats 0xffffffff as a valid IRQ number and panics at some # point. # # A fix was recently merged in skiboot: # # e97391ae2bb5 ("xive: fix return value of opal_xive_allocate_irq()") # # but we need a workaround anyway to support older skiboots already # in the field. # # Internally convert 0xffffffff to OPAL_RESOURCE which is the usual error # returned upon resource exhaustion. # # Cc: stable@vger.kernel.org # v4.12+ # Signed-off-by: Greg Kurz # Reviewed-by: Cédric Le Goater # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/156821713818.1985334.14123187368108582810.stgit@bahia.lan # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 6ccb4ac2bf8a35c694ead92f8ac5530a16e8f2c8 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powernv_defconfig+NO_RADIX_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- powernv_defconfig # Added to kconfig CONFIG_PPC_RADIX_MMU=n # yes \n | make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powernv_defconfig+NO_RADIX_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powernv_defconfig+NO_RADIX_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/mm/book3s64/pgtable.c: In function 'flush_partition': /kisskb/src/arch/powerpc/mm/book3s64/pgtable.c:216:3: error: implicit declaration of function 'radix__flush_all_lpid_guest'; did you mean 'radix__flush_all_lpid'?
