bjh21 1d4ae5d285 Use int_off_save and int_restore rather than int_off and int_on. 2001-08-20 23:28:05 +00:00
bjh21 45b5bdc5e5 Split off the pm_entries array from the rest of struct pmap. This makes 
memory allocation for it more efficient (since pm_entries is 4096 bytes long),
and will allow pm_entries to be freed for swapped processes.

bjh21 8ec27f2ebe Implementation of fiq_{get,set}regs. 
Also, don't leave space for a FIQ handler in kernels with no FIQing devices.
 2001-08-20 23:10:51 +00:00
bjh21 13f36f67c6 Don't initialise a podule's loader multiple times. 2001-08-20 23:09:12 +00:00
bjh21 9aa4896361 More FIQ support. This gives me enough to handle FIQs, and to downgrade them 
to IRQs as necessary.  All these interfaces are subject to change in the light
of experience.

bjh21 1061e51a8a One from the vaults: Add lint stubs. 2001-08-20 22:56:10 +00:00
chris 140252be2b Arm has a vac, so we must use pmap_enter/remove for vmapbuf rather than k* versions, otherwise we may not be doing the right caching thing. 2001-08-20 21:52:09 +00:00
matt 078a9a2206 Netwinders have ISC phys, not LXT phys. 2001-08-20 16:17:12 +00:00

chs 9e8e4c5bdc I was wrong, sh4 does have a VAC. 
change vmapbuf()/vmunmapbuf() back to using pmap_enter()/pmap_remove().
 2001-08-19 20:44:41 +00:00

bjh21 8b7128e398 Changes in aid of FIQ support: 
Add ioc_fiq_setmask().
  Change ioc_irq_status_full() to use the request registers rather than the
  status registers.  This is brings it into line with the Unix baclplane, and
  makes detecting downgraded FIQs possible.
 2001-08-19 15:27:44 +00:00
matt 4bc8190b62 Change local offset/label for irqhandlers to Lirqhandlers. Because in 
ELF _C_LABEL(irqhandlers) == irqhandlers so we were getting self-referential
pointer which causes the IRQ to fall on itself.  [With this change the
netwinder kernel can now be *ELF* and boots to multiuser]
 2001-08-19 07:29:26 +00:00
matt 7cab3778d5 Make EXEC_ELF32 support std now, 2001-08-19 05:51:09 +00:00
wdk 12a212bc5c Add support for WD33C93 controller and assosiated SCSI devices, and enable 
by default.
 2001-08-19 03:20:36 +00:00
wdk 0ac0d0d4e4 Initial implementation of WD33C9x SCSI driver for SGI IP22 platforms. 
Based on mvme68k and Atari drivers for the same chipset with the
addition of bus_space support.  Attempts have been made to seperate out the
machine dependent dma components and more work is required in this area.

Tested on SGI R4K Indy, but has little testing on other platforms.

wiz e320555c3b if_il.c lives in dev/qbus now, and is mentioned in dev/qbus/files.uba. 
Remove commented out line for it.
 2001-08-18 14:52:37 +00:00
enami b605664b49 Include bsd.own.mk a bit earlier so that make cleandir works. 2001-08-18 12:53:58 +00:00
enami cebeb402de Fix white space usage. 2001-08-18 12:48:59 +00:00
wiz a5226c0bb5 Remove files describing hp300/HPBSD. 
Can still be found in sys/arch/hp300/DOC as Debug.tips and HPMMU.notes.
Okay'd by is.

eeh 94751b6adc Make the kernel a tad bigger. 2001-08-18 04:55:29 +00:00
simonb 11362870f4 Reorder some function prototypes more logically. 2001-08-18 04:13:28 +00:00
eeh 20df032dec Make lint happier. 2001-08-18 03:47:18 +00:00
simonb 02f580ae38 Fix lint problem introduced in last change - if `lint' is defined, 
#define away __alignof__.  Still produces some warnings, but at least
they're not fatal anymore.

Problem noted by Rafal Boni in private mail.

fredette e5769f5f01 Sometimes the ec board reports a packet length that's too large. 
Try to deal with this by clipping the packet length, and, under
DEBUG, printf when we do.  Also zero out the packet status in
the buffer before we give it back to the board.

ur e6c008bb48 Disable PCI expansion ROM for normal operation. 
It fixes memory mapped I/O problems on some devices.

simonb 0667c562f6 Describe the widths of various coprocessor 0 registers (for mips1, 
mips3, mips32 and mips64).
 2001-08-17 07:53:33 +00:00
simonb dd6c57e790 Fix for single-byte mbufs. 2001-08-17 07:21:07 +00:00
simonb b2b2f7ccfa Fix va_arg() problem when adjusting argument pointer when a structure is 
passed which is larger than an int but has int alignment.  As well as
fixing the described problem, this is the same way it is handled in the
Irix and Ultrix header files.

Problem and suggested solution by Uros Prestor in port-mips mailling
list.

chs dda1ba2993 implement pmap_k{enter_pa,remove}() correctly. 
remove various checks for impossible conditions.
other misc cleanup.
tested by tohru.

fredette 8b21bb0078 Under DEBUG, have a global buserr_reg that stores the 
last value read out of the bus error register.
 2001-08-17 00:00:26 +00:00
eeh 73ff12bf97 Bump version. 2001-08-16 23:57:08 +00:00
fredette ba289d7421 Now treat the bus error register as 16-bits wide, even 
though it has nothing in the top half.  Reading it as
only 8 bits can sometimes give erroneous values.  Under
DEBUG, also stash the value read in the buserr_reg global,
since the value is only latched until read.
 2001-08-16 23:54:31 +00:00
fredette 3a6e3c55cb Added the crucial "packed" attribute to the type 8 frame structure. 2001-08-16 23:45:12 +00:00
fredette aeb5917f66 Made prom_putchar and prom_putstr use the PROM putchar 
function instead of framebuffer functions.  This makes
serial consoles work again.

rearnsha d47e5736c8 ANSIfy function declarations and prototypes. Tidy up include files. 
Minor reformatting.
 2001-08-15 22:28:15 +00:00
rearnsha 0d9806035b Include sys/types.h, sys/callout.h and machine/intr.h. Don't include 
sys/disklabel.h or sys/dkstat.h.
