For # example, we've had: # # 1ff688209e2e ("watchdog: core: make sure the watchdog_worker is not deferred") # 8d5755b3f77b ("watchdog: softdog: fire watchdog even if softirqs do not get to run") # 217f69743681 ("net: busy-poll: allow preemption in sk_busy_loop()") # # all of which worked around some of the effects of that commit. # # The DVB people have also complained that the commit causes excessive USB # URB latencies, which seems to be due to the USB code using tasklets to # schedule USB traffic. This seems to be an issue mainly when already # living on the edge, but waiting for ksoftirqd to handle it really does # seem to cause excessive latencies. # # Now Hanna Hawa reports that this issue isn't just limited to USB URB and # DVB, but also causes timeout problems for the Marvell SoC team: # # "I'm facing kernel panic issue while running raid 5 on sata disks # connected to Macchiatobin (Marvell community board with Armada-8040 # SoC with 4 ARMv8 cores of CA72) Raid 5 built with Marvell DMA engine # and async_tx mechanism (ASYNC_TX_DMA [=y]); the DMA driver (mv_xor_v2) # uses a tasklet to clean the done descriptors from the queue" # # The latency problem causes a panic: # # mv_xor_v2 f0400000.xor: dma_sync_wait: timeout! # Kernel panic - not syncing: async_tx_quiesce: DMA error waiting for transaction # # We've discussed simply just reverting the original commit entirely, and # also much more involved solutions (with per-softirq threads etc). This # patch is intentionally stupid and fairly limited, because the issue # still remains, and the other solutions either got sidetracked or had # other issues. # # We should probably also consider the timer softirqs to be synchronous # and not be delayed to ksoftirqd (since they were the issue with the # earlier watchdog problems), but that should be done as a separate patch. # This does only the tasklet cases. # # Reported-and-tested-by: Hanna Hawa <hannah@marvell.com> # Reported-and-tested-by: Josef Griebichler <griebichler.josef@gmx.at> # Reported-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> # Cc: Alan Stern <stern@rowland.harvard.edu> # Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> # Cc: Eric Dumazet <edumazet@google.com> # Cc: Ingo Molnar <mingo@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 3c53776e29f81719efcf8f7a6e30cdf753bee94d # < make -s -j 10 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0xE9A4F876 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig # yes \n \| make -s -j 10 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 10 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/arch/powerpc/include/asm/mmu.h:338:0, from /kisskb/src/arch/powerpc/include/asm/paca.h:22, from /kisskb/src/arch/powerpc/include/asm/hw_irq.h:64, from /kisskb/src/arch/powerpc/include/asm/irqflags.h:12, from /kisskb/src/include/linux/irqflags.h:16, from /kisskb/src/include/linux/spinlock.h:54, from /kisskb/src/include/linux/wait.h:9, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/scripts/gdb/linux/constants.py.in:15: /kisskb/src/arch/powerpc/include/asm/mmu-book3e.h:275:2: error: #error Unsupported page size #error Unsupported page size ^ In file included from /kisskb/src/arch/powerpc/include/asm/mmu.h:338:0, from /kisskb/src/arch/powerpc/include/asm/paca.h:22, from /kisskb/src/arch/powerpc/include/asm/hw_irq.h:64, from /kisskb/src/arch/powerpc/include/asm/irqflags.h:12, from /kisskb/src/include/linux/irqflags.h:16, from /kisskb/src/include/linux/spinlock.h:54, from /kisskb/src/include/linux/seqlock.h:36, from /kisskb/src/include/linux/time.h:6, from /kisskb/src/include/linux/stat.h:19, from /kisskb/src/include/linux/compat.h:12, from /kisskb/src/arch/powerpc/kernel/asm-offsets.c:16: /kisskb/src/arch/powerpc/include/asm/mmu-book3e.h:275:2: error: #error Unsupported page size #error Unsupported page size ^ /kisskb/src/scripts/gdb/linux/Makefile:19: recipe for target 'scripts/gdb/linux/constants.py' failed make[3]: * [scripts/gdb/linux/constants.py] Error 1 /kisskb/src/./Kbuild:81: recipe for target 'build_constants_py' failed make[2]: * [build_constants_py] Error 2 make[2]: * Waiting for unfinished jobs....
