- Remove hppa_cpu_init()
Thanks for picking up my patches and integrating them properly
with the reset code.
But sadly your changes somehow break hppa 64-bit CPU support.
I think it's to when the reset code is called.
Easy reproducer (no other options/disc/network needed):
./qemu-system-hppa -smp cpus=4 -nographic -machine C3700

- Reset PSW using M bit (untested)
We haven't implemented PSW-M support and the first
thing the firmware does is to reprogram PSW.
So, basically it's not needed.
Helge, could we add a functional test booting Linux?
What exactly are you looking for?
Some trivial preinstalled disc image with kernels?
Any examples?
Your [*] example running SeaBIOS is perfect.
See tests/functional/test_riscv_opensbi.py, but using:
wait_for_console_pattern('SeaBIOS PA-RISC 64-bit Firmware')
Then I suggest 2 testcases (32-bit and 64-bit CPU, dropped SMP flag):
./qemu-system-hppa -nographic -machine B160L
./qemu-system-hppa -nographic -machine C3700
