However, in one heavily interrupt-driven SMT1 # workload, some regression was observed. This patch adds a kvm_hv # module parameter called h_ipi_redirect to control this feature. # # The default value for this tunable is 1 - that is enable the feature. # # Signed-off-by: Suresh Warrier # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 6f5701c04edc0b4d00d482117c89a7a13d647b5f # < make -s -j 8 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64e_defconfig In file included from scripts/kconfig/zconf.tab.c:2576: /kisskb/src/scripts/kconfig/confdata.c: In function 'conf_write': /kisskb/src/scripts/kconfig/confdata.c:770:19: warning: '%s' directive writing likely 7 or more bytes into a region of size between 1 and 4097 [-Wformat-overflow=] 770 | sprintf(newname, "%s%s", dirname, basename); | ^~~~~~ /kisskb/src/scripts/kconfig/confdata.c:770:19: note: assuming directive output of 7 bytes /kisskb/src/scripts/kconfig/confdata.c:770:2: note: 'sprintf' output 1 or more bytes (assuming 4104) into a destination of size 4097 770 | sprintf(newname, "%s%s", dirname, basename); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/scripts/kconfig/confdata.c:773:20: warning: '.tmpconfig.' directive writing 11 bytes into a region of size between 1 and 4097 [-Wformat-overflow=] 773 | sprintf(tmpname, "%s.tmpconfig.%d", dirname, (int)getpid()); | ^~~~~~~~~~~~~~~~~ /kisskb/src/scripts/kconfig/confdata.c:773:3: note: 'sprintf' output between 13 and 4119 bytes into a destination of size 4097 773 | sprintf(tmpname, "%s.tmpconfig.%d", dirname, (int)getpid()); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # < make -s -j 8 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 8 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/lib/string_64.S: Assembler messages: /kisskb/src/arch/powerpc/lib/string_64.S:194: Warning: invalid register expression /kisskb/src/arch/powerpc/lib/copypage_power7.S: Assembler messages: /kisskb/src/arch/powerpc/lib/copypage_power7.S:48: Warning: invalid register expression /kisskb/src/arch/powerpc/lib/copypage_power7.S:49: Warning: invalid register expression /kisskb/src/arch/powerpc/lib/copypage_power7.S:51: Warning: invalid register expression /kisskb/src/arch/powerpc/lib/copypage_power7.S:52: Warning: invalid register expression /kisskb/src/arch/powerpc/lib/copypage_power7.S:54: Warning: invalid register expression /kisskb/src/arch/powerpc/kernel/vdso64/gettimeofday.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/vdso64/gettimeofday.S:148: Warning: invalid register expression /kisskb/src/arch/powerpc/kernel/vdso64/gettimeofday.S:148: Error: operand out of range (4 is not between 0 and 1) /kisskb/src/arch/powerpc/kernel/vdso64/gettimeofday.S:148: Error: missing operand make[3]: *** [/kisskb/src/arch/powerpc/kernel/vdso64/Makefile:35: arch/powerpc/kernel/vdso64/gettimeofday.o] Error 1 make[2]: *** [/kisskb/src/scripts/Makefile.build:403: arch/powerpc/kernel/vdso64] Error 2 make[1]: *** [/kisskb/src/Makefile:943: arch/powerpc/kernel] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [Makefile:146: sub-make] Error 2 Command 'make -s -j 8 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc64e_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/mpe-0day_ppc64e_defconfig_powerpc-gcc4.9 # Build took: 0:00:51.248365
