scw 1a0a12c5b4 Bah. Somehow the a.out versions of the bootxx symbols got deleted; put 
them back.
 2000-12-09 22:33:24 +00:00
scw a3dc741c03 Delete the commented out EXEC_ELF32 now that it's in std.mvme68k. 
(Spotted by Simon Burge)

matt 2e13ae83bc cpp/lorder/mkdep don't have cross specific versions. 2000-12-09 20:42:06 +00:00
bjh21 559ea94aca Fix arguments to ktrsys*() functions. 2000-12-09 18:57:17 +00:00
bjh21 6d66ade542 We no longer have zeropage.S. It was merged into locore.S last week. 2000-12-09 18:54:01 +00:00
bjh21 86dd29d1f5 Add a definition of BUS_SPACE_ALIGNED_POINTER. 2000-12-09 18:47:15 +00:00
bjh21 8df54708da If we get an odd IOEB type, tell the user. I have a feeling issue 1 A5000s 
might trip this.

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 3e0d9a1b4a Fix multiple-file loading. Bump version number to 0.41. 2000-12-09 13:30:25 +00:00
jdolecek 44d7fef20a make locore.s call emulation-specific syscall code directly 
this should improve speed of emulation syscall path (avoids one function call,
and emulations syscall can use the trapframe trick)
Idea: Charles Hannum
 2000-12-09 13:20:04 +00:00
jdolecek 6f0fceeb1d the call to emulation-specific syscall function will be handled differently, 
don't do it explicitly
 2000-12-09 12:57:17 +00:00
jdolecek 87a6bee3a9 prototype ibcs2_syscall() in compat/ibcs2/ibcs2_exec.c 2000-12-09 12:45:44 +00:00
jdolecek 8f9b01eba1 prototype svr4_syscall() (only) in compat/svr4/svr4_exec.c 2000-12-09 12:44:26 +00:00
jdolecek 45144cbd17 put userret() into header file machine/userret.h and pull it where needed 2000-12-09 11:21:52 +00:00
mjacob af2807f9f7 Finally fix this driver to be sensible about the ENDIAN dance. It's not 
quite simply a question of the Qlogic being little endian and having
to have stuff swapped on big endian machines- it also has to do with the
fact that the SBus and PCI DMA layouts are wierd with respect to this.

At any rate, now finally fixed- works on Mac G4, tested it on a SS10
for sparc, checked on alpha to see if I've broken anything, and as
soon as I get another spare afternoon I'll finally install a sparc64
version which should just work (as it'll be like the Mac).

mycroft b2052e5951 GC garbage in userret() and *_syscall(). 2000-12-09 06:34:07 +00:00
mycroft afc49e36eb Set md_regs before call the alternate syscall handler. 
Remove the EMUL_HAS_SYS___syscall test, because the handler is no longer shared
with SVR4.
Rather than comparing with e_nsysent, just mask the value.  This is only done
to protect us from malicious programs anyway.
 2000-12-09 06:33:15 +00:00
mycroft 3340782619 Add a separate svr4_syscall(). 2000-12-09 06:30:54 +00:00
briggs cd0841b357 Clear interrupts on the Apple "Boogie" card. Information grovelling 
and testing by Lucas Lay.

mycroft 7a70c438c8 Couple more tweaks to eliminate unnecessary cycles. 2000-12-09 02:46:17 +00:00
mycroft 57fdd67be5 Do the resched check *only* on an AST. 
Also, there is no reason to save the original PC; there are no restartable
syscalls that change the PC -- and even if there were, they wouldn't do it
in the restart case.
 2000-12-09 02:18:16 +00:00
mycroft 5415a63e13 Rework the way the nested task and trace flags are handled when entering the 
old (lcall) syscall gate.  This speeds up that path a little.
 2000-12-08 23:14:04 +00:00
mycroft 985a81f23b GC unneeded code. 2000-12-08 22:32:09 +00:00
mycroft 73e35a46eb Increase all of the limits. 2000-12-08 21:51:35 +00:00
martin d9d7c42e0c Remove esp specific function from ddb when esp @ sbus is not included 
in the kernel config. Makes compiling sbus-less kernels possible again.

nisimura 8df2fd7ff9 A forgotten commit that should be done at the time when zs_ioasic.c was 
changed.

itohy c8ca4dd604 Add register prefix in asm() directives. 2000-12-08 03:00:05 +00:00
itohy 5d2d4230c8 Fix asm() directive. 2000-12-08 02:59:38 +00:00
itohy c2245838be 1. Add register prefix.

bjh21 4c4e11c0f8 Merge zero page into the start of locore. This allows us to just map the 
start of the kernel text segment in at address 0 to get zero-page properly
mapped.  This should save us one page, but that may need a bit of extra
shuffling before we can easily tell UVM about it.

scw 3c748b810f Missed this one in yesterday's bootloader commits: 
Change BUGCRT from bugcrt.o to bugstart.o.

bjh21 2d96994642 It seems that i-cubed used the "A" suffix on card types (along with "Lk" and 
probably some others) to indicate the software mix on the card, while we
were using it to indicate Acorn-branded variants.  Change over to using "AEH"
for the latter.

bjh21 65cdac60a6 It seems that i-cubed used the "A" suffix on card types (along with "Lk" and 
probably some others) to indicate the software mix on the card, while we
were using it to indicate Acorn-branded variants.  Change over to using "AEH"
for the latter, and while we're at it clean up the descrptions and add some
that were missing.

thorpej ac083d0b74 Use a pool cache for PDPs. This results in a 20% improvement in a 
loop of 10000 fork/exit operations on a 400MHz Celeron.

jdolecek ce6253238c convert to use genassym.cf & genassym.sh, as other ports do 2000-12-07 17:51:06 +00:00
jdolecek 101ce19db1 generate dependencies for assym.h for make depend, fix dependency 
for maxusers (make assym.h depend on Makefile)

thorpej 0abaa8b70d Nothing calls pmap_release() except for pmap_destroy(). Merge the two. 2000-12-07 17:12:21 +00:00
thorpej b4b01fe8e6 Nothing calls pmap_pinit() except for pmap_create(), so merge the two. 2000-12-07 17:09:26 +00:00

kleink 9cee15bd12 In the ELF toolchain, use __mcount instead of mcount. 2000-12-07 10:14:08 +00:00
scw 3f7cfb70ef Add "options COMPAT_AOUT_M68K". 2000-12-07 08:40:06 +00:00
thorpej 5c7e0ada43 Use a pool cache for L1 PT pages. When we can allocate a cached, 
constructed L1 PT page, this saves us from having to copy the kernel
L1 PTEs into the user L1 PT page at fork time (it's already set up).

A simple test shows a 1 second improvement of a rapid fork/exit operation
10000 times on a 533MHz 21164A (12s to 11s).
