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 # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # <
