These delays # were due to the emulation of certain MMIO operations controlling # memory layout, which were emulated with one expedited grace period per # access. Common configurations required thousands of boot-time MMIO # accesses, and thus thousands of boot-time expedited SRCU grace # periods. # # In these configurations, the occasional sleeps that allowed KLP to # proceed caused excessive boot delays. These commits preserve enough # sleeps to permit KLP to proceed, but few enough that the virtual # embedded kernels still boot reasonably quickly. # # This represents a regression introduced in the v5.19 merge window, and # the bug is causing significant inconvenience" # # * tag 'rcu-urgent.2022.07.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: # srcu: Make expedited RCU grace periods block even less frequently # srcu: Block less aggressively for expedited grace periods # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 4ba1329cbb9456c937bff1ed8ad4ca91ab75eab6 # < make -s -j 32 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- defconfig # < make -s -j 32 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 32 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 32 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.19-178.5: Warning (pci_device_reg): /pci@14000000/pci2_root@0,0,0: PCI unit address format error, expected "0,0" Completed OK # rm -rf /kisskb/build/linus_mips-defconfig_mips-gcc8 # Build took: 0:01:14.640946
