thorpej 1951c4b19b Bump KNMEMCLUSTERS slightly, and make it more obvious how to tune it 
(lifted from i386 port).
 1998-02-10 03:53:01 +00:00
thorpej 68d3b764ce Make it easier to keep the scaled VM_*_SIZE values in sync w/ the 
constants.

is cb1085870c Add the LIMITMEM workaround for the kernel address space size problem. 
Will be removed as soon as the kernel can auto-adapt to its address space.

mrg e92c7d991e KNF. 1998-02-09 14:35:48 +00:00
mrg 7d3aef40b3 keep statistics on pageout/pagein, total pages, and total operations. 1998-02-09 13:08:22 +00:00
thorpej eda74e6121 - Perform all necessary bus_dmamap_sync() operations. 
- Greatly simplify allocation and DMA mapping of the mailbox and ccbs.
- Be more robust against resource shortage errors, and report errors better.
 1998-02-09 10:53:07 +00:00
thorpej 5fe6759646 Fix serial console support, which was broken by the previous revision: 
- In the console getc routine, block until a character becomes ready
  (no, really, we mean it).  This routine should _never_ time out.
- In the console putc routine, if the UART has trouble, do NOT proceed
  to print a diagnostic message, which would recursively invoke the
  console putc routine ad nauseum.

mrg 3112d4b3e1 KNF. 1998-02-09 04:05:36 +00:00
scottb 2ee5fa7f17 iBCS2 code cleanup 
added support for ELF binaries
added support for ELF shared libs via mmap code borrowed from svr4_misc.c
incorporated a few XENIX patches from Andreas Wrede <andreas@planix.com>
 1998-02-09 02:30:42 +00:00
scottb 876dc027a1 added support for SCO UNIX (derived from iBCS2) 1998-02-09 01:29:10 +00:00
mrg 7ff12d37cc fill out vmtotals: t_free, t_vm, t_avm, t_rm and t_arm. leaves shared of same, and t_pw. 1998-02-08 22:23:33 +00:00
thorpej da21f06eb5 Remove the pager options; they're in std.sparc, and will stay there 
until UVM is no longer optional.
 1998-02-08 19:24:28 +00:00
thorpej 93b0450b6a Back out previous change (again, grrrr). 1998-02-08 19:23:20 +00:00
kleink 7cf291e0dd Add ENOMSG. 1998-02-08 19:04:31 +00:00
thorpej 223caea788 pmap_page_index() is not used in the MACHINE_NEW_NONCONTIG case. 1998-02-08 18:47:06 +00:00
thorpej 2f55a48f5c Implement MACHINE_NEW_NONCONTIG and switch the hp300 port to use it. 1998-02-08 18:37:55 +00:00
thorpej 39f8b8c99b Round allocations to page size in uvm_pageboot_alloc(). 1998-02-08 18:27:30 +00:00
thorpej d319b28938 Round allocations to page size in vm_bootstrap_steal_memory(). 1998-02-08 18:24:52 +00:00
tv 40f13df5bc the *PAGER options were moved to the generic config files, but not moved 
out of here (causes duplicate opeion errors) -- fix.

mrg 6122fae970 KNF 1998-02-08 16:07:57 +00:00
mrg bc3395e590 turn of UVM history logging by default. 1998-02-08 14:19:21 +00:00
ragge c5b2acd27f Split out MSCP floppies as a separate device (rx) instead of handling 
them as disk drives. It is now also allowed to change floppies without
the system complaining :-)
 1998-02-08 14:03:45 +00:00
thorpej 54aa7dfae0 Correct a think'o I made some time ago, and note that the dump routines 
here are broken if VME memory cards exist in the system.
 1998-02-08 09:33:14 +00:00
mrg d9b2f81e27 move pdhist initialisation to the same place as maphist. also, declare 
the history buffers are "struct uvm_history_ent" to ensure proper
alignment (eg, alpha).  this fixes a boottime panic when the pdhist was
used before it had been initialised.
 1998-02-08 07:52:28 +00:00
thorpej 1305ecbe62 Allow callers of uvm_km_suballoc() to specify where the base of the 
submap _must_ begin, by adding a "fixed" boolean argument.
 1998-02-08 06:15:53 +00:00
gwr 22c20779d0 Rewrite the match/attch routines to use the P4 register 
(when it exists).  Also get the size right; other fixes.
 1998-02-08 05:22:08 +00:00
gwr 0378cb2ff6 Define the CG4B_OFF_* values to be relative to the location of 
the P4 register so the probe routine finds the P4 at off=0.
 1998-02-08 05:20:08 +00:00
gwr 99fd045ec0 Add fb_eeprom_setsize() for setting the FB size based on the EEPROM 
value (to be used only if unit=0).  Add P4 helper functions:
fb_pfour_id, fb_pfour_setsize, fb_pfour_{get,set}_video

gwr ab8340e9da cosmetic 1998-02-08 05:13:17 +00:00
gwr 0bc9d95f95 Move the sun3-vs-sun3x stuff into std.sun3 and std.sun3x 
Configure P4 frame buffers at the address of their P4 reg.
Move messy Sun3 bw2 and cg4 configs to included files.
 1998-02-08 05:10:45 +00:00
gwr e3400ad779 Improve some diagnostics. 1998-02-08 05:07:06 +00:00
gwr 5b69e41858 Default the interrupt priority in match functions. 1998-02-08 05:05:54 +00:00
gwr 5193e1e30e Factor *peek out of bus_subr.c and move it to autoconf.c 
(to reduce duplication).  Add bus_tmapin and bus_tmapout
for use in probe functions (gets a temporary mapping).
Add bus_mapout() to undo bus_mapin() if needed.

gwr e387ffba22 Add pmap_map 1998-02-08 04:57:58 +00:00

pk cc06ca6693 * Add the "VIPER 150/21531" to quirk list (ST_Q_SENSE_HELP). 
* Double timeout on tape position commands to 30 minutes. Some units
  seem capable of taking that much time.
 1998-02-07 23:00:24 +00:00
pk 334b20bbd6 Define a `DMA_FLUSH' macro; dma chip revs 0 & 1 have a different bit 
to reset the internal state engine.
 1998-02-07 22:41:27 +00:00
thorpej 8e8eed4ba7 Create RX DMA maps with ALLOCNOW. These maps are essentially always 
loaded, and recovering from a resource shortage error is much harder
in the receive case.
 1998-02-07 21:13:34 +00:00
thorpej f955aa86e5 Properly handle error conditions from bus_dmamap_load_mbuf(). 1998-02-07 20:40:35 +00:00
