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_mpc83xx_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc83xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/mpc832x_rdb.dtb: Warning (interrupts_property): /qe@e0100000/mdio@3120/ethernet-phy@0:#interrupt-cells: size is (4), expected multiple of 8 arch/powerpc/boot/mpc832x_rdb.dtb: Warning (interrupts_property): /qe@e0100000/mdio@3120/ethernet-phy@4:#interrupt-cells: size is (4), expected multiple of 8 INFO: Uncompressed kernel (size 0x5ff6b0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff6b0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff6b0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff6b0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff6b0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff6b0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5eef98) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5ff6b0) 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 01:59:23 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3038818 Bytes = 2967.60 kB = 2.90 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:59:23 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3062991 Bytes = 2991.20 kB = 2.92 MB Load Address: 00600000 Entry Point: 006001f4 Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:59:23 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3062327 Bytes = 2990.55 kB = 2.92 MB Load Address: 00600000 Entry Point: 006001f4 Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:59:23 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3063278 Bytes = 2991.48 kB = 2.92 MB Load Address: 00600000 Entry Point: 006001f4 Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:59:23 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3063716 Bytes = 2991.91 kB = 2.92 MB Load Address: 00600000 Entry Point: 006001f4 Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:59:23 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3062351 Bytes = 2990.58 kB = 2.92 MB Load Address: 00600000 Entry Point: 006001f4 Image Name: Linux-4.17.0-rc3-gce77a98 Created: Fri Jun 1 01:59:23 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3063195 Bytes = 2991.40 kB = 2.92 MB Load Address: 00600000 Entry Point: 006001f4 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-5.3 # Build took: 0:00:42.473828
