aba39b410c Don't forget to initialise 'sc' on entry to the attach function ... 2002-08-26 10:45:55 +00:00

a1ed033a09 Hardcode FEMI base and top addresses, at least until I figure out 
how to interpet VCR.MB_TOP and VCR.MB_BOT in some reasonable way.

a57d38854c Save SSR and SPC while in the critical section of an exception. The 
previous behaviour of storing them with SR.BL clear was in breach
of the SH5 documentation.

Make an effort to catch PANIC traps and dump machine state to the console.

abc568b5e1 In cpu_fork(), if p1 == curproc, call sh5_savectx() to ensure the 
pcb contains valid state before copying it to p2's pcb.
Previously, we just lazy-sync the fpu state. This wasn't quite good
enough if p1 had not previously slept.

d8f6a57b15 Re-work pmap_bootstrap_mapping() to pmap_map_device() to provide a 
way for bus_space(9) to efficiently map device memory. (Although at
the moment, it doesn't quite work as efficiently as it will down
the line ...)

Fix a pool_init() botch.

Add a debug aid: dump_kipt(). This can be called from ddb(4) in order
to (partially) dump the contents of the kernel IPT.

16ba45622a - Drop to ddb(4) on kernel traps. 
- Dump more machine state on kernel traps (for when ddb isn't an option).
- Add rudimentary support for PANIC exceptions.

b5273356dc - Invalidate insn/operand caches before setting up the mmu for the first time. 
- Clear SR.FD to enable the FPU. Seems like it starts up disabled. If the
  core has no FPU, this is a nop.

- Preserve the debug bits (step/watch) in an attempt to appease the debugger.

911776caaf Impose a limit on the time we spin waiting for the DTF host to ack 
our packet. Seems like the ack for the initial posix console "open"
packet never arrives, even though it completes successfully.

94791afd65 No longer use BTLB entries to map the entire address spaces of I/O subsystems, 
since BTLB entries can be scarce and very little of an I/O subsystem normally
needs to be mapped.

Instead, the pmap now allows mappings of I/O space to be entered with
pmap_kenter_pa.  bus_space mappings for small amounts of I/O space (as for
virtually all devices) are made this way, with BTLB entries still used for
large mappings for things like framebuffers.

This has led to more and cleaned-up uses of bus_space(9) and has caused
some autoconf cleanup.  Also, kgdb is now attached and connected before
autoconfiguration, which is much earlier than before.
