So let's fix it by # skipping the IOMMU group setup for opencapi PHBs. # # Fixes: 0bd971676e68 ("powerpc/powernv/npu: Add compound IOMMU groups") # Signed-off-by: Frederic Barrat <fbarrat@linux.ibm.com> # Reviewed-by: Greg Kurz <groug@kaod.org> # Reviewed-by: Andrew Donnellan <andrew.donnellan@au1.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /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 2542f2f17eb335c13f525e523319ba59f2fd82a0 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x3126261B # 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=y # Added to kconfig CONFIG_PPC64=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_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/exceptions-64e.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/exceptions-64e.S:587: Error: unrecognized opcode: `mc_btb_flush' make[3]: * [/kisskb/src/scripts/Makefile.build:367: arch/powerpc/kernel/exceptions-64e.o] Error 1 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:492: arch/powerpc/kernel] Error 2 make[1]: * [/kisskb/src/Makefile:1042: arch/powerpc] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:152: sub-make] Error 2 Command 'make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-gcc5 # Build took: 0:01:41.051002
