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 24 ARCH=powerpc O=/kisskb/build/mpe-0day_pmac32_defconfig+SMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_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()); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # Added to kconfig CONFIG_SMP=y # < make -s -j 24 ARCH=powerpc O=/kisskb/build/mpe-0day_pmac32_defconfig+SMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/mpe-0day_pmac32_defconfig+SMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:3374:warning: override: reassigning to symbol SMP # make -s -j 24 ARCH=powerpc O=/kisskb/build/mpe-0day_pmac32_defconfig+SMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/l2cr_6xx.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/l2cr_6xx.S:184: Warning: invalid register expression /kisskb/src/arch/powerpc/kernel/l2cr_6xx.S:331: Warning: invalid register expression /kisskb/src/crypto/wp512.c: In function 'wp512_process_buffer': /kisskb/src/crypto/wp512.c:987:1: warning: the frame size of 1088 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ In file included from /kisskb/src/sound/ppc/pmac.h:25:0, from /kisskb/src/sound/ppc/awacs.c:29: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:219:2: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0); ^ /kisskb/src/sound/ppc/awacs.c:886:36: note: 'speaker_vol' was declared here struct snd_kcontrol *master_vol, *speaker_vol; ^ In file included from /kisskb/src/sound/ppc/pmac.h:25:0, from /kisskb/src/sound/ppc/awacs.c:29: /kisskb/src/include/sound/control.h:219:2: warning: 'master_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0); ^ /kisskb/src/sound/ppc/awacs.c:886:23: note: 'master_vol' was declared here struct snd_kcontrol *master_vol, *speaker_vol; ^ /kisskb/src/net/netfilter/nfnetlink_queue.c: In function '__nfqnl_enqueue_packet': /kisskb/src/net/netfilter/nfnetlink_queue.c:519:19: warning: 'nfnl_ct' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ct && nfnl_ct->build(skb, ct, ctinfo, NFQA_CT, NFQA_CT_INFO) < 0) ^ /kisskb/src/net/netfilter/nfnetlink_queue.c:316:23: note: 'nfnl_ct' was declared here struct nfnl_ct_hook *nfnl_ct; ^ WARNING: modpost: Found 1 section mismatch(es).
