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 10 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc40x_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc40x_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 10 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc40x_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 10 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc40x_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc40x_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_40x.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_40x.S:881: Warning: invalid register expression INFO: Uncompressed kernel (size 0x4a7cb0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4a7cb0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x497580) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4a7cb0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4a7cb0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.4.0-rc2-g6f5701c04edc Created: Wed May 13 19:02:24 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2278682 Bytes = 2225.28 KiB = 2.17 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.4.0-rc2-g6f5701c04edc Created: Wed May 13 19:02:24 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2306975 Bytes = 2252.91 KiB = 2.20 MiB Load Address: 00500000 Entry Point: 00501358 Image Name: Linux-4.4.0-rc2-g6f5701c04edc Created: Wed May 13 19:02:24 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2307185 Bytes = 2253.11 KiB = 2.20 MiB Load Address: 00500000 Entry Point: 00501550 Completed OK # rm -rf /kisskb/build/mpe-0day_ppc40x_defconfig_powerpc-gcc4.9 # Build took: 0:01:13.153740
