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 <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/hppa-linux/bin/hppa-linux-gcc --version # < git log --format=%s --max-count=1 ce77a983b603b21b1b4b209fd264011f09064af5 # < make -s -j 80 ARCH=parisc O=/kisskb/build/powerpc-next_parisc-defconfig_parisc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/hppa-linux/bin/hppa-linux- defconfig # make -s -j 80 ARCH=parisc O=/kisskb/build/powerpc-next_parisc-defconfig_parisc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/hppa-linux/bin/hppa-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2041:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:340:21: note: 'pdeo' was declared here /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1822:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1732:46: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-next_parisc-defconfig_parisc # Build took: 0:00:54.719801
