 2001-01-03 10:08:55 +00:00
bjh21 b3eae7d1c8 Since we need to have an aout_machdep.h, we may as well borrow the arm32 one. 2000-12-29 23:08:31 +00:00
bjh21 36f8a8d0f8 Purge vestiges of a.out support. 2000-12-29 23:07:29 +00:00
bjh21 00a01e20d8 Sync with arm32. No functional changes. 2000-12-29 22:42:23 +00:00
bjh21 df10cbcda9 Sync with arm32 (fixes warnings compiling /bin/sh and probably others). 2000-12-29 19:30:34 +00:00
matt a589927cbc Make identical to arm32 version. (add same parens, use __P, etc.) 2000-12-28 03:55:14 +00:00
matt f1f4acfb4d Remove reference to CLBYTES 2000-12-28 03:54:15 +00:00

bjh21 9822871467 Add a special call to uvm_page_physload to register RISC OS's zero page as 
free at startup.
 2000-12-27 20:43:44 +00:00
bjh21 1b364c5082 pmap_confess() is unused and doesn't work any more. G/C it. 2000-12-27 18:38:50 +00:00
itojun efa2b7073c make mbstate_t bigger (32 -> 128 bytes). 
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare).  really sorry
for the mess.

bjh21 95920110c7 Stub FPU driver -- identifies FPUs and warns they aren't supported. e.g: 
cpu0 (root): ARM2
fpu0 at cpu0: FPPC/WE32206
fpu0: WARNING: FPU type not supported by kernel
 2000-12-23 13:37:02 +00:00
itojun 823498203f populate _BSD_MBSTATE_T_. add warning regarding to rune_t. 2000-12-21 06:03:47 +00:00
bjh21 395a883e48 Pull across arm32 rev 1.19: 
Remove ALTENTRY().  It's dangerous and should not be used.
 2000-12-14 20:50:56 +00:00
bjh21 a6b4048c85 Get ELF RCSIDs back 2000-12-14 20:26:42 +00:00
bjh21 14198dc0bd Sync with arm32 -- they've got ELF stuff there these days. 2000-12-14 19:28:12 +00:00
bjh21 4f1ee09e5f It looks like UBC_WINSIZE needs to be at least PAGE_SIZE. 2000-12-10 14:28:45 +00:00
bjh21 4f5619bc7c Prototype kdb_trap(). 2000-12-10 01:31:48 +00:00
bjh21 86dd29d1f5 Add a definition of BUS_SPACE_ALIGNED_POINTER. 2000-12-09 18:47:15 +00:00
bjh21 38d918f85f Proper support for the Unix backplane in those machines that have one. 
Not very well-tested, but it seems to work.
 2000-12-09 17:52:44 +00:00
bjh21 facbe746d0 Provide friendly names for the IRQs as they're wired in normal machines. 2000-12-09 15:16:01 +00:00
bjh21 9307dc5373 Reduce default UBC_NWINS to save precious KVM. 2000-11-30 20:59:36 +00:00
bjh21 32b19479ca Drastically reduce PAGER_MAP_SIZE so we don't run out of KVM so soon. 2000-11-30 12:16:00 +00:00
bjh21 3112fd4f14 Add a pmap_steal_memory implementation. This has two good consequences. 
First, it reduces the kernel text segment by 1k or so.
Second, it should enable me to eventually allocate the pv_table dynamically.
 2000-09-23 11:10:58 +00:00
bjh21 7c9498f7cb Move setsoftast() and friends into cpu.h and make them into macros, so arm26 
is the same as every other port (except arm32).
 2000-08-25 16:43:46 +00:00
thorpej 4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This 
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.
 2000-08-25 01:04:06 +00:00
bjh21 769e82477f Move contents of <machine/spl.h> to <machine/intr.h>. 
Add IST_* macros to <machine/intr.h>, mostly for the feature-list tickbox.
Generally tidy up.
 2000-08-22 21:27:21 +00:00
thorpej 58e7a6954b Add spllock(). See spl(9) for details. 2000-08-22 19:46:26 +00:00
bjh21 a776e1268d General cleanup of definitions of translation table stuff. 
Also add PPN[8] for the A540.  Now all I need are two more RAM cards for my
A540 so I can test it.
 2000-08-21 14:37:51 +00:00
thorpej 23a7f255d4 Make sure we provide splsched() as described in spl(9). 2000-08-21 02:06:31 +00:00
bjh21 567f2768d1 Implement the easy ptrace requests and turn off the difficult ones. 2000-08-20 15:16:49 +00:00
bjh21 999646a30b Add some extra levels for MI drivers. 2000-08-16 23:58:29 +00:00
tshiozak dec20dab0e set MB_LEN_MAX to 32. I forgot the modification for arm26 yesterday. 2000-08-09 16:43:59 +00:00
itojun d738f90fd7 raise MSIZE from 128 to 256. 
- for sizeof(void *) == 8 arch, this is mandatory.  MHLEN is too small
  already (less than 80) and there are chances for unwanted packet loss due
  to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
  (even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
  extension header)

portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.

kleink bb2ed0f487 G/c _BSD_INTPTR_T_ and _BSD_UINTPTR_T_. 2000-06-27 05:53:22 +00:00
kleink 47b5c5e3b1 Resolve some formatting nits; add __intptr_t and __uintptr_t. 2000-06-27 04:58:51 +00:00
kleink e695f72a2e Add <machine/int_types.h>, which provides namespace-pure definitions 
of exact-width integer types.
 2000-06-26 15:42:16 +00:00
kleink 133ea38323 Add a WEAK_ALIAS() macro. 2000-06-23 12:18:45 +00:00

bjh21 ece024b6cf Un-__Pify. 2000-06-08 10:49:19 +00:00
thorpej a7d0570e67 First sweep at scheduler state cleanup. Collect MI scheduler 
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.
