However, the test doesn't always segfault, causing the test to run a # single time. # # This patch fixes the test by putting it within a loop and jumping, via # setcontext, just prior to the loop in case it segfaults. This way we get the # desired behavior (run the test COUNT_MAX times) regardless if it segfaults or # not. This also reduces the use of setcontext for control flow logic, keeping it # only in the segfault handler. # # Also, since 'count' is changed within the signal handler, it is declared as # volatile to prevent any compiler optimization getting confused with # asynchronous changes. # # Signed-off-by: Gustavo Luiz Duarte <gustavold@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200203160906.24482-3-gustavold@linux.ibm.com # < /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 4399efc3f2f04ad8e6948461795de04ed1358402 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig+NO_SPLPAR_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig # Added to kconfig CONFIG_PPC_SPLPAR=n # yes \n \| make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig+NO_SPLPAR_ppc64le-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 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig+NO_SPLPAR_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: vmlinux.o(.text+0x2e1c): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
