Today, the IPI is not created for such nodes, and hot-plugged # CPUs use a bogus IPI, which leads to soft lockups. # # We could create the node IPI on demand but it is a bit complex because # this code would be called under bringup_up() and some IRQ locking is # being done. The simplest solution is to create the IPIs for all nodes # at startup. # # Fixes: 7dcc37b3eff9 ("powerpc/xive: Map one IPI interrupt per node") # Cc: stable@vger.kernel.org # v5.13 # Reported-by: Geetika Moolchandani # Signed-off-by: Cédric Le Goater # Tested-by: Laurent Vivier # Tested-by: Srikar Dronamraju # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20210629131542.743888-1-clg@kaod.org # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 de17ea0120bbdcec33983489c58dc6acb2281c3c # < make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: File format not recognized /kisskb/src/kernel/trace/trace_osnoise.c: In function 'start_kthread': /kisskb/src/kernel/trace/trace_osnoise.c:1461:8: warning: 'main' is usually a function [-Wmain] void *main = osnoise_main; ^~~~ /kisskb/src/lib/test_scanf.c: In function 'numbers_list_field_width_val_width': /kisskb/src/lib/test_scanf.c:530:1: warning: the frame size of 2472 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/test_scanf.c: In function 'numbers_list_field_width_typemax': /kisskb/src/lib/test_scanf.c:488:1: warning: the frame size of 2952 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/test_scanf.c: In function 'numbers_list': /kisskb/src/lib/test_scanf.c:437:1: warning: the frame size of 2480 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info mm/kfence/kfence_test.o: file not recognized: File format not recognized make[3]: *** [/kisskb/src/scripts/Makefile.modfinal:76: mm/kfence/kfence_test.ko] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/scripts/Makefile.modpost:156: __modpost] Error 2 make[1]: *** [/kisskb/src/Makefile:1757: modules] Error 2 make: *** [Makefile:220: __sub-make] Error 2 Command 'make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 # Build took: 0:29:13.297385
