bsh 7b6639153c make atomic_{set,clear}_bit() inline for arm32 ports, and 
add <machine/atomic.h> for them.

scw 7feac76e17 Tick off a few more items, and add a new one. 2002-10-19 11:13:11 +00:00
scw 873eee59ff Add fast assembler versions of in_cksum() and in4_cksum(). 
(Well, as fast as can be expected on a cpu with no carry flag)
 2002-10-19 09:01:44 +00:00
scw 80b7fbca17 Ditch the crude and slow bytewise copyin()/copyout()/kcopy() code in favour 
of the asm memcpy() in libkern.
 2002-10-19 08:56:45 +00:00
scw 1e0542ac19 Fix a spurious looping PC/FP message when we stop due to not finding 
the caller's stack frame.
 2002-10-19 08:50:30 +00:00
scw c01b319dcc There seem to be some stability problems with the scif serial port driver 
at the moment, possibly as a side-effect of some yet-to-be-committed SH5
speed-ups.

Work-around it for now by using com0 as the console.
 2002-10-19 08:43:32 +00:00
scw 472a1ad6b2 When setting up to probe a com(4) port for use as the console, make sure 
the port is powered up and configured correctly.

junyoung abbf53bb9c Add NEW_BUFQ_STRATEGY (disabled by default). 2002-10-19 05:58:25 +00:00
junyoung 7e4d58b1b8 Move NEW_BUFQ_STRATEGY to misc options section. 2002-10-19 05:55:09 +00:00
bjh21 a531a4ae8e Undo recent cpu_switch register usage changes in order to decrease nathanw_sa 
merge pain.

bjh21 7dd8880e90 The grand cpu_switch register reshuffle! 
In particular, use r8 to hold the old process, and r7 for medium-term
scratch, saving r0-r3 for things we don't need saved over function
calls.  This gets rid of five register-to-register MOVs.
 2002-10-18 23:06:33 +00:00
bjh21 3d1b6867f0 In cpu_switch(), stack more registers at the start of the function, 
and hence save fewer into the PCB.  This should give me enough free
registers in cpu_switch to tidy things up and support MULTIPROCESSOR
properly.  While we're here, make the stacked registers into an
APCS stack frame, so that DDB backtraces through cpu_switch() will
work.

This also affects cpu_fork(), which has to fabricate a switchframe and
PCB for the new process.

wrstuden 0ce4a385a5 Should have done this sooner. Bump to version 1.7 to indicate good 
alloc.c.

(sync with GENERIC)

junyoung e4b7588c28 Add NEW_BUFQ_STRATEGY (disabled by default). 2002-10-18 15:11:08 +00:00
scw a7be530a95 Add code to support tracing back through a stackframe which was created 
using a "movi imm, Rn / sub R15, RN, R15" pair. This is how the compiler
creates frames which are too big to fit in the immediate field of "addi";
something which happens a lot with -O0 ...

While I'm here, add a simple heuristic to detect infinite loops caused by
tracing back through some non-leaf asm routines which don't set up frames.

grant f525c02fbe remove 'UT' from fxp and rtk, as these have been tested and known 
to work. some whitespace cleanup.

thorpej b000f2251b * Add "struct device" to the softc. 
* Add missing notice.

Problems pointed out by Jonathan Stone.

jdolecek 3a80cf174b initSH3(): prefix the extern edata[], end[] with '_', so that the kernel links 
XXX this is probably wrong, other sh3 platforms don't need/have this

jdolecek e7bc7ac4bd tsc_microtime(): use splclock() for !MULTIPROCESSOR (cosmetic, this is used 
for MULTIPROCESSOR only currently)

mycroft 64f9a5eccd Fix a sign extension bug that caused pmap_growkernel() to fail with >2GB KVA. 
Symptom observed and verified fixed by tls.

petrov d7612810f1 Add wscons devices, sync with sparc. 2002-10-16 17:52:09 +00:00
martin f47b939a22 Since we now use pmap_kenter_pa, which ignores PMAP_LITTLE, don't bother 
to pass that as flags. We've already changed the ASIs used to access the
mapped pages acordingly.

bjh21 441e8907fe Switch to using the MI C versions of setrunqueue() and remrunqueue(). 
GCC produces almost exactly the same instructions as the hand-assembled
versions, albeit in a different order.  It even found one place where it
could shave one off.  Its insistence on creating a stack frame might slow
things down marginally, but not, I think, enough to matter.

junyoung fb173f7efd Add (commented out) VGA_RASTERCONSOLE. 2002-10-15 18:20:58 +00:00
thorpej dbdee1d904 The zstty device must have an interface attribute in order for 
children to attach; it is not sufficient to have an interface
atttribute which only happens to have the same name.

Fix the same mistake with the sabtty declaration.

jdc 86fda61426 Uncomment audioamd0 at obio0. 2002-10-15 13:53:01 +00:00

audioamd0 at obio0 slot 0 offset 0x500000 level 13 softpri 4
  audio0 at audioamd0: full duplex

bjh21 d599df9587 Continue the " - . - 8" purge. Specifically: 
add	rd, pc, #foo - . - 8		->	adr	rd, foo
ldr	rd, [pc, #foo - . - 8]		->	ldr	rd, foo

Also, when saving the return address for a function pointer call, use
"mov lr, pc" just before the call unless the return address is somewhere
other than just after the call site.

Finally, a few obvious little micro-optimisations like using LDR directly
rather than ADR followed by LDR, and loading directly into PC rather than
bouncing via R0.
