christos 830c5c171a Implement passing AT_{E,R}{U,G}ID in the elf aux vector, like solaris. 
- pass struct proc to copyargs.
- eliminate svr4_copyargs, since it is the same as ours now.

/etc/rc.d/fu: WARNING: $fu is not set properly - see rc.conf(5).
Add a note to rc.conf that third party packages may test for additional
variables.

ad 7a2589c16e - Must now get some info from the kernel, not the board. 
- Don't try to do things that the firmware can't handle.

augustss 731d1eccf2 Get rid of sysctl for setting BCM2033 firmware path. It doesn't work 
for ports that don't include files.usb, and it's also not done quite
the way it should.

scw f7982b5823 Another item on the TODO list: 
Add support for cpus where sizeof(register_t) is not necessarily
	the same as sizeof(void *). This is the case on SH5 using the
	ILP32 ABI. On this cpu db_expr_t is, necessarily, 64-bits.
	Unfortunately, in ILP32 mode, ddb will only display the low 32-bits
	of any expression, including registers...
 2002-08-26 11:35:22 +00:00
scw a82718b34d Casting from a pointer, to a db_expr_t, has to go via an intptr_t. 
(db_expr_t == int64_t on sh5, for example).
 2002-08-26 11:34:27 +00:00
scw 41e5042829 Pointers must be cast to {,u}intptr_t before they can be cast to register_t, 
at least on sh5, where sizeof(register_t) != sizeof(void *) in ILP32 mode.

yamt d3538cc488 sync partly with tcpdump.org. ok'ed by itojun 
patches #454 from yamt@mwd.biglobe.ne.jp
- avoid optimization involving subtract operations
- correct optimization of bitwise operations

TODO: re-introduce subtract optimization
 2002-08-26 11:21:18 +00:00
scw 2ccf86d7da Re-sync with current reality. 
Add options DDB.
Add debug makeoptions.
G/C some unnecessary stuff.
 2002-08-26 11:16:02 +00:00
scw ce2ec9e63e Add support for the SMsC LAN83C183 PHY, which actually probes as a 
Seeq 84220.

Also add an 84220-specific work-around for some braindamage (at least
in the PHY I'm working with) where the PHY always comes out of reset
isolated, regardless of the previous state of the BMCR_ISO bit. This
happens even if the PHY has address zero, which is contrary to the
part's datasheet...

The work-around is only applied if we notice BMCR_ISO is set when it
should be clear following reset. The fix is to wait 30mS and clear
it manually. (The change doesn't stick if it's cleared sooner than this)
 2002-08-26 11:13:13 +00:00
scw 9bcd736b9d Attach sm(4) at superio, instead of the previous isa bus attachment. 
The latter's probe doesn't pick up the ethernet controller, and the
attach function needs to set MIIF_NOISOLATE.
We attach it at superio mainly because they share the same region of
address space, and the ethernet controller's interrupt is routed
through the superio.

scw fe7de4db3f Need <machine/db_machdep.h> 2002-08-26 10:58:38 +00:00
scw a1fda8f587 Call ddb_init() right after initialising the console. 
We have no symbols at this time (due to lack of a bootloader)
so just hardcode symbol length to zero for now.
 2002-08-26 10:55:39 +00:00
scw 0eb22d79b4 Try to preserve more bits in the status register (e.g. trace/watch). 
Bump the (currently hardcoded) size of onboard RAM to match the Cayman.

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

scw 3ad3b8c856 Add MD ddb(4) files. 2002-08-26 10:39:43 +00:00
scw 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.

scw 40f78dcc13 Use pmap_map_device() to map device registers. 2002-08-26 10:35:40 +00:00

scw 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.

scw 0a00df79a0 Initialise to zero the memory allocated for interrupt handles. 2002-08-26 10:26:28 +00:00
scw d2c90421b8 Enable h/w interrupts before returning from cpu_configure(). 2002-08-26 10:24:57 +00:00
scw bc8042954a - Add a debug check for SR.BL being set on entry to cpu_switch(). 
- Add sh5_savectx()
- Fix a branch target register botch in sh5_fpsave() and sh5_fprestore().

scw 7bd8b94a66 Wrap dump_kipt() in #ifdef DDB. 2002-08-26 10:21:54 +00:00
scw 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.
 2002-08-26 10:21:04 +00:00
scw 2774f9d77b Basic ddb(4) support. 
Still to do:
 - disassembly
 - breakpoints
 - single-step
 - stack trace
 2002-08-26 10:16:44 +00:00
scw 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.
 2002-08-26 10:14:02 +00:00
scw d454acf190 Disable the checks for unsupported hz values for now. At least until I 
can fix the peripheral bridge's PLL1 clock ratio.

scw 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.
 2002-08-26 10:08:02 +00:00
scw 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.

the licensing of the 4.4BSD encumbered files are solved.
