Bochs smp debug [SOLVED]

alkot · Post by **alkot** » Tue Jan 29, 2008 2:09 am

Hi,
I'm trying to get my IPI on SMP configuration work and need to get bochs internal debugger stop at second AP, bochs successfully stopped at int 3, but that's all

-- I cant get it to show anything about second CPU (regs, idt etc) Searched through bochs docs and cant find any command to show regs on certain cpu.
Can anyone help me solve this problem?

Is your version of bochs definately compiled with the SMP option enabled?

Yes, compiled by myself from cvs with my config

cygwin config

Code: Select all

CC="gcc"
CXX="g++"
CFLAGS="-O3 -Wall -Wno-format -march=pentium"
CXXFLAGS="$CFLAGS"

export CC
export CXX
export CFLAGS
export CXXFLAGS

./configure --enable-all-optimizations \
            --enable-cpu-level=6 \
            --enable-sse=2 \
            --enable-pci \
            --enable-acpi \
            --enable-show-ips \
            --enable-smp \
            --enable-apic \
            --enable-debugger \
            --enable-disasm \
            --with-win32

Just found it in bochs source code -- you just need to execute in internal debugger

Code: Select all

set $cpu=<number of cpu you want to view>

Thanks alot
