Boot log on ThinkPad X200 #9

Open zamaudio opened 4 years ago

zamaudio commented 4 years ago

With patches (https://github.com/zamaudio/GNUMach_SMP/tree/gcc9-smp-debian) I got it to boot with network on native hardware. Keystrokes not working, ssh worked. Here is log from my terminal over ssh!

BTW I just applied the debian patches from gnumach debian packaging, plus a small fix to the docs and copied the compiler-gcc8.h to gcc9

AlmuHS commented 4 years ago

Could you attach here the link to these patches?. And the instructions about how to apply them.

And, btw, if you can access via ssh, can you execute the commands nproc and nproc --all ?

AlmuHS commented 4 years ago

ok. I've just compiled your patched microkernel, and It works!! nproc show 2 cpus.

But all process continues executing in CPU 0. Even compiling a code with make -j2 (to generate 2 threads), both threads executes in CPU 0.

Can you send me a Pull Request? To create a new branch with the patches, and simplify the test

zamaudio commented 4 years ago

Hey @AlmuHS, did your recent thread_info thing fix the problem with keyboard interrupts? With just my patch above, my x200 keyboard is stuck.

AlmuHS commented 4 years ago

I haven't test It in real hardware yet. But, in Qemu, the tty don't reply to keyboard.

My thread_info patch is for another problem: I want to know what processor runs every thread
