Under qemu-system-sparc, I found a problem with OBP's psr commands.
On an real SS-20, I get:
ok .psr
CWP: 4 ET: 1 PS: 1 S: 1 PIL: f EF: 1 EC: 0 ICC: nZvc VER: 0
IMPL: 4
ok %psr .
40401fe4
But with qemu, it all shows up as 0, such as:
ok .psr
CWP: 0 ET: 0 PS: 0 S: 0 PIL: 0 EF: 0 EC: 0 ICC: nzvc VER: 0
IMPL: 0
ok %psr .
0
while "info registers" says the psr should be 40001de0.
Any suggestion of how to debug this?
Bob
