Message-ID: <marc-linux-ultrasparc-90222358530997@msgid-missing> (raw)
I am trying to debug the ultralinux kernel (sparc64 using prom ver
3.0). After doing a dload, I try to disassemble, but it just shows a
bunch of illtraps.
ok 4000 dload /tftpboot/vmlinux.aout
ok 404000 dis
<Shows a bunch of illtrap instructions>
ok 404000 map?
<shows PADDR = 404000>
Is the `map?' command using dTLB entries ? How can I see which
Physical Addr does the vaddr 404000 map to in the iTLB ?
Also, setting a breakpoint to 404000 has no effect.
I would be grateful if someone can explain how to read the iTLB
mappings to specify the correct physical address in the `dis' command.
