itohy 6736303e13 Use assembly version of ffs(3). 2002-08-24 06:39:48 +00:00
itohy 85ce1de27f Oops, SYSLIBC_SCCS -> LIBC_SCCS 2002-08-24 06:37:24 +00:00
itohy 70b5675025 Assembly version of ffs(3). 
Confirmed to return the same value as that of the C version.

The results of a simple benchmark on SH-4 200MHz, is shown below.
I think this shows acceptable performance.

return value	C version	this version	speed
of ffs()	(ns/call)	(ns/call)	ratio

thorpej 41c25cb648 Add autoconfiguration support for the Sun4d "bootbus". Add a 
zs @ bootbus attachment.
 2002-08-24 05:26:56 +00:00
mhitch 89fd7196ed Add missing PMAP_TLB_SHOOTDOWN() after PMAP_INVALIDATE_TLB() in 
pmap_page_protect().  Closes NetBSD Problem Report #18045.
 2002-08-24 03:10:52 +00:00
thorpej ffdedb6d80 In pmap_map_in_l1() and pmap_unmap_in_l1(), make sure that the VA 
that is passed in is already aligned to a 4M super-section.
 2002-08-24 03:10:40 +00:00
thorpej d158b3a37a When we allocate a PTP, make sure the offset we specify is for 
the 4M super-section that the PTP will map, not some random 1M
chunk of it.  This gives the PTP hint code a much better chance
to working properly, and allows us to tidy up the code that
flushes a PTP from the cache in pmap_destroy().
 2002-08-24 02:50:53 +00:00
thorpej aafe6e006c Define macros describing the 4M super-sections that our pmap 
actually uses (since we allocate PT pages in 4K chunks, rather
than 1K chunks).
 2002-08-24 02:48:50 +00:00
thorpej 77a6866508 Enable caching on kernel and user page tables. This saves having 
to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).

We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).

lukem 6aeb2c119f if RESCUEDIR is defined, use ${RESCUEDIR}/sh as _PATH_ALTSHELL 2002-08-24 01:05:14 +00:00
lukem 9f3703ab9a - use _PATH_ALTSHELL (which defaults to _PATH_BSHELL) as the default ALTSHELL 
(as opposed to _PATH_BSHELL), to allow the ALTSHELL to be changed.
- print the full path to the default shell in the ALTSHELL prompt.
 2002-08-24 01:02:51 +00:00
lukem a14ac7834b now that we have working rescue tools, there's no need to force 
LDSTATIC=-static for init(8) on people who want LDSTATIC=""
 2002-08-24 01:00:18 +00:00
lukem fe84c3ffb2 support -sh as a synonym for sh 2002-08-24 00:51:12 +00:00
lukem 141ac20efe only print "init: trying /some/init" if RB_ASKNAME or if it's not the first 
path we're trying.  (the intent but not the behaviour of the previous rev.)
 2002-08-24 00:47:17 +00:00
thorpej bb0558df3e Oops, don't need a DMA tag. 2002-08-23 21:49:13 +00:00
matt 2d290eb699 Use the qtype_FOREACH macros. Print out address of hook that could not 
be disestablished.
 2002-08-23 20:50:25 +00:00
thorpej a71473b576 Add autoconfiguration glue for the Sun4d "cpu-unit". Each processor 
board has 2 CPU units (one for each processor), one of which also has
a "bootbus", to which the serial ports, etc. are attached.

We can now probe/attach CPUs on a SPARCserver 1000.

bouyer 86514a3c90 Note support for HPT372 and (better late than never) HPT374. 2002-08-23 16:31:09 +00:00
itojun a8b4aa9a72 #if 0 out call to rnd_add_uint32() in interrupt logic until thorpej 
measures performance differences.
 2002-08-23 16:30:10 +00:00
bouyer ceb355fe05 Add support for Promise Ultra133TX2, and Ultra133TX2v2. 2002-08-23 16:29:37 +00:00
bouyer 0d17a940f8 Add support for HPT372. From sdegler@kashmir.degler.net in kern/17908, 
with some improvement from me, and from FreeBSD.
 2002-08-23 16:24:54 +00:00
itojun 36e473ebb2 off-by-one. PR 18049 
correct snprintf() return value handling in another place.
 2002-08-23 16:10:42 +00:00
matt ffdea2c266 Only do the dssall if cpu_altivec is set. 2002-08-23 16:08:10 +00:00
bouyer 1a7bae9619 Add support for Promise Ultra133TX2 and Ultra133TX2v2, from FreeBSD and 
stephen@degler.net in kern/17509.
 2002-08-23 16:02:32 +00:00
bouyer ea9862cb62 Regen: Add Promise Ultra133TX2 and Ultra133TX2v2 PCI ID 2002-08-23 15:57:04 +00:00
bouyer f49156d31c Add Promise Ultra133TX2 and Ultra133TX2v2 PCI ID. 2002-08-23 15:56:30 +00:00
scw b3e086e0ce Attach the ECC driver instead of the previous "eccirq" property hack. 2002-08-23 15:03:33 +00:00
scw 5b79fdfaf7 Add "ecc at plb" device. 
Add an "irq" locator to the plb device.
This gets rid of the original hack where ecc support was wedged into
the cpu driver.
 2002-08-23 15:01:07 +00:00
simonb 3502025a54 Show the IRQ we attach the ECC handler to. 2002-08-23 13:43:18 +00:00
simonb a9560f7ab2 Don't pass PROP_CONST to board_info_set() for variables that are on 
the stack; we want to copy the property into the database.
 2002-08-23 13:41:55 +00:00
scw 3a0067a42a Comment out wscons-related options until port-specific code is written. 2002-08-23 13:16:23 +00:00
scw 27ff9862b3 Override the last commit by auto-generating the file from walnut's 
etc.MAKEDEV.

Pointed out by Thomas Klausner.
 2002-08-23 13:01:21 +00:00
scw 50e32c42df Make the comments at the top match reality. 
G/C a couple of other unused devices.

As a precaution, comment out the wscons entries until
the kernel supports it and note that their major numbers
will need to be re-synced.
 2002-08-23 12:58:37 +00:00
scw 9ba60b4297 Install the ECC error interrupt handler at the level specified by 
a "4xx-ecc-irq" property.
If the property isn't defined, assume the hardware has no ECC support.
This should, ideally, be a config file option.
 2002-08-23 12:46:49 +00:00
scw a97e0cd99d G/C satlink and wscons. Neither are applicable to the walnut port. 2002-08-23 12:18:46 +00:00
scw a625cf764a Don't create satlink or ttyE device nodes. The former clashed with tty00, 
and the latter (wscons) doesn't exist on Walnut anyway.
Renumber ttyCY to match Walnut's conf.c.
 2002-08-23 12:18:06 +00:00
wiz d4a8d9ed9e Remove duplicate 'is' reported by Arto Huusko in misc/18048. 2002-08-23 12:04:39 +00:00
scw c4fdfebd38 Allow port-specific Makefiles to override the name and location 
of locore.[So].
This is in preparation for arch/evbppc.
 2002-08-23 12:01:58 +00:00
scw a0d58bf2f5 Remove an extra trailing bracket in a DEBUG printf. 2002-08-23 11:59:40 +00:00
scw f384fe8ba7 Don't assume all com ports run at "COM_FREQ", or a multiple thereof. 
Use a board-specific property instead.
 2002-08-23 11:42:13 +00:00
scw 19c988633d Don't frob cpu-specific DCR registers in common code. 2002-08-23 11:40:07 +00:00
scw 4968573654 Split off common 4xx locore code so it can be re-used by other 4xx ports. 2002-08-23 11:37:53 +00:00
wiz 4a20060b4c Fix typo. 2002-08-23 10:39:46 +00:00
tron 85f89e9c20 Adapt minor number of "libutil". 2002-08-23 10:35:36 +00:00
tron ef63cbff6b Bump minor number to 3 because there are already systems with 
"libutil.so.6.2" to avoid further problems.
 2002-08-23 10:34:02 +00:00
ragge 3f5fba68de Do not try to use "__builtin_ffs" on vax, ffs is an instruction already. 
Maybe possible to teach gcc to use it?
 2002-08-23 08:45:27 +00:00
kanaoka d4a4b29e36 - Support -4 and -6. Approved by itojun. 2002-08-23 08:14:20 +00:00
itojun e68a39d27b attach random number source. 2002-08-23 07:45:39 +00:00
lukem 76f5313c64 in start_init(), if RB_ASKNAME is set in boothowto, ask for the path 
name to start up as init (rather than just cycling thru initpaths[]
and panicing when out of options).  if RB_ASKNAME isn't set, the old
behaviour remains.  inspired by changes in der Mouse's patchtree.
resolves [kern/18027] from me.
