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-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 6ccb4ac2bf8a35c694ead92f8ac5530a16e8f2c8 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc5200_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/platforms/52xx/lite5200_sleep.S: Assembler messages: /kisskb/src/arch/powerpc/platforms/52xx/lite5200_sleep.S:184: Warning: invalid register expression INFO: Uncompressed kernel (size 0x6f38f4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6f38f4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6f38f4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6e3210) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-5.3.0-rc2-g6ccb4ac2bf8a Created: Fri Sep 13 21:47:43 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3543385 Bytes = 3460.34 KiB = 3.38 MiB Load Address: 00700000 Entry Point: 00700284 Image Name: Linux-5.3.0-rc2-g6ccb4ac2bf8a Created: Fri Sep 13 21:47:43 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3543328 Bytes = 3460.28 KiB = 3.38 MiB Load Address: 00700000 Entry Point: 00700284 Image Name: Linux-5.3.0-rc2-g6ccb4ac2bf8a Created: Fri Sep 13 21:47:44 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3541916 Bytes = 3458.90 KiB = 3.38 MiB Load Address: 00700000 Entry Point: 00700284 Image Name: Linux-5.3.0-rc2-g6ccb4ac2bf8a Created: Fri Sep 13 21:47:44 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3514629 Bytes = 3432.25 KiB = 3.35 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc5 # Build took: 0:01:15.892579
