[SeaBIOS] [PATCH v3 0/3] fix PS/2 keyboard initialization failures

Posted by Volker Rümelin 2 years, 10 months ago

Hi,

I wrote a few patches for qemu [1] and patch 10/11 exposes a bug
in seabios.

Sometimes the PS/2 keyboard initialization fails and seabios
doesn't detect the keyboard. This patch fixes the PS/2 keyboard
initialization.

I wouldn't be surprised if my patch also fixes PS/2 keyboard
initialization problems on bare metal. A few bug reports look
very similar to what I see on my computer with qemu.

With best regards,
Volker

v2:
Kevin suggested to call check_irqs() in run_thread().

v3:
Add a new patch to fix the asm constraints in run_thread(). The
changes are required for the next patch.

Kevin suggested to call check_irqs() after the new thread ran in
run_thread().
Fixed an error in the commit message.

Call check_irqs() after switch_next() in yield().
