But as each instruction is dumped on a # single line, that's still a lot of output. If you're on a slow console # that can take multiple minutes to print. If you were "just popping in # and out of xmon quickly before the RCU/hardlockup detector fires" you # are now having a bad day. # # Things are not as bad with 'd' because we print 16 bytes per line, so # it's fewer lines. But it's still quite a lot. # # So shrink the maximum for 'd' to 64K (one page), which is 4096 lines. # For 'di' add a new limit which is the above / 4 - because instructions # are 4 bytes, meaning again we can dump one page. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 8e9ad2720cd1cf55530755362ad899f69e09fb9a # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mgcoge_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mgcoge_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mgcoge_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_32.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_32.S:946: Warning: invalid register expression Completed OK # rm -rf /kisskb/build/powerpc-next_mgcoge_defconfig_powerpc-gcc5 # Build took: 0:00:49.789491
