However OPAL events are not # particularly performance or latency critical, so they can all be # invoked by kopald. # # This patch removes the irq_work queueing, and instead wakes up # kopald when there is an event to be processed. kopald processes # interrupts individually, enabling irqs and calling cond_resched # between each one to minimise latencies. # # Event handlers themselves should still use threaded handlers, # workqueues, etc. as necessary to avoid high interrupts-off latencies # within any single interrupt. # # Signed-off-by: Nicholas Piggin # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 ce77a983b603b21b1b4b209fd264011f09064af5 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 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:223:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0);
