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/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 ce77a983b603b21b1b4b209fd264011f09064af5 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc834x_itxgp_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 83xx/mpc834x_itxgp_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc834x_itxgp_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-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/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2497:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1819:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here /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 INFO: Uncompressed kernel (size 0x52cc60) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x52cc60) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x51c5b4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:21:46 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2589971 Bytes = 2529.27 kB = 2.47 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:21:46 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2613757 Bytes = 2552.50 kB = 2.49 MB Load Address: 00600000 Entry Point: 00600230 Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:21:46 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2613409 Bytes = 2552.16 kB = 2.49 MB Load Address: 00600000 Entry Point: 00600230 Completed OK # rm -rf /kisskb/build/powerpc-next_83xx_mpc834x_itxgp_defconfig_powerpc # Build took: 0:00:33.383753
