tsubai 668b553d53 Need opt_compat_netbsd.h. 1999-11-22 13:26:59 +00:00
lonhyn 090c4d2e66 Program to convert back and forth between PPM and CHRP boot icon images. 1999-11-19 00:43:20 +00:00
kleink eac5784583 Move signal management code common to all PowerPC platforms (sendsig(), 
sigreturn(), sigcode) to a single place in the shared powerpc directory.
(The struct sigcontext etc. definitions were already being shared.)

thorpej 1946167939 Update for pmap_enter() API change. No functional difference. 1999-11-13 00:30:26 +00:00
kleink 522cbf0248 Update to match new SVR4-style definition names in <sys/exec_elf.h>. 1999-10-25 13:55:06 +00:00
jdolecek 7f589dba84 rename the MD Debugger() to cpu_Debugger() 
add MI Debugger() which switches to console if wscons is used prior
to calling cpu_Debugger()

chs 3bfa86cbc0 fix breakage from PMAP_NEW cleanup. 1999-09-14 17:11:45 +00:00
chs f3a668ed84 eliminate the PMAP_NEW option by making it required for all ports. 
ports which previously had no support for PMAP_NEW now implement
the pmap_k* interfaces as wrappers around the non-k versions.
 1999-09-12 01:16:55 +00:00
tsubai 30e635f6f3 Make sure that we use only inside of available memory region 
in pmap_bootstrap.
 1999-08-30 07:59:19 +00:00
simonb 3c185af5fd Include <sys/endian.h> after defining whether where are little- or 
big-endian.  i386, pc532 and vax still include <machine/byte_swap.h>
and define macros for the {n,h}to{h,n}*() functions.  mips also
defines some endian-independent assembly-code aliases for unaligned
memory accesses.
 1999-08-21 05:53:50 +00:00
simonb 06a92524c2 Include <sys/bswap.h> for function prototypes. i386, pc532 and vax 
still include <machine/byte_swap.h> and define macros for some of
the bswap*() functions.

tsubai 183ef12cd5 Adapt pmap_extract() change. 1999-07-11 17:44:08 +00:00
thorpej 3ebbe095e0 Change the pmap_extract() interface to: 
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
This makes it possible for the pmap to map physical address 0.

danw 9d4f4eebdb reorder the fp_rnd constants to match the values used by the 
powerpc fpu
 1999-07-07 01:52:26 +00:00
thorpej 0288ffb53a pmap_change_wiring() -> pmap_unwire(). 1999-06-17 19:23:20 +00:00
thorpej f5a527bb4e Remove pmap_pageable(); no pmap implements it, and it is not really useful, 
because pmap_enter()/pmap_change_wiring() (soon to be pmap_unwire())
communicate the information in greater detail.
 1999-06-17 18:21:21 +00:00
thorpej beb8d06638 Generally update the comment above vunmapbuf(). 1999-05-26 22:19:33 +00:00
thorpej a2d06a4721 Generally update the comment above the vmapbuf() implementations. 1999-05-26 22:07:36 +00:00
thorpej c10a926030 Allow the caller to specify a stack for the child process. If NULL, 
the child inherits the stack pointer from the parent (traditional
behavior).  Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.

This is required for clone(2).

tsubai 0e57d44e45 Add missing CPU_MAXID definition. 1999-05-05 11:20:54 +00:00
tsubai 6168467392 Add cpu.h. 1999-05-05 10:15:53 +00:00
tsubai fdabab77f2 PT_{STEP,GETREGS,SETREGS} support. 1999-05-03 10:02:19 +00:00
kleink 5cbe23baad Garbage-collect VM_MBUF_SIZE leftover. 1999-05-02 18:12:32 +00:00
ws 5423093850 Modify syncicache on PowerPC from an inline to a real function. 
Support different cache line sizes with the same object code in userland.
While here, move the function to implementation name space.
 1999-04-17 21:16:45 +00:00
thorpej 4b603c180a Use the same hack as pmap_zero_page() and pmap_copy_page() to provide 
direct-mapped pool pages.
 1999-04-16 21:45:19 +00:00
chs f455dd6596 add a `flags' argument to uvm_pagealloc_strat(). 
define a flag UVM_PGA_USERESERVE to allow non-kernel object
allocations to use pages from the reserve.
use the new flag for allocations in pmap modules.

mycroft 9c6b797796 Changes for modified pmap_enter() API: 
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
  because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
  avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot.  Also, DO NOT use
  pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
  access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
  access_type = 0.  This should probably be revisited.

tsubai 82b3b0209f In copyin() and copyout(), clear the pcb_onfault variable in the EFAULT 
case. (pr 7243)
 1999-03-26 08:32:15 +00:00
tsubai 38a92c9752 A successful kernel page fault should just return so that signal delivery 
et al. should not executed.  (pr7240)
 1999-03-26 08:15:23 +00:00
mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

thorpej 63b6321834 VM_MBUF_SIZE is in terms of MCLBYTES, not CLBYTES. 1999-03-23 00:31:59 +00:00
chs 31839fe71d fix previous, I got carried away with cut+paste. 1999-03-22 08:44:37 +00:00
thorpej a77ccfe460 Garbage-collect. 1999-03-20 01:40:25 +00:00
chs ab7269f62a if uvm_fault() fails with KERN_RESOURCE_SHORTAGE, send a SIGKILL 
and print a message about it.  this will be used to recover from
out-of-swap conditions.
 1999-03-18 04:56:01 +00:00
tsubai b4374e3ce0 Implement badaddr() and trap machine-check in badaddr. 1999-03-15 01:29:07 +00:00
tsubai 61fbe51007 First-cut of profiling support. 
XXX userland only, for now.

tsubai 96f0fb14a1 Add RSS accounting. 1999-03-05 06:10:48 +00:00
tsubai 01614b7217 Implement pmap_procwr(). 
(Not tested.  gdb doesn't work on powerpc yet.)

chuck 9cb41178b7 MNN is no longer optional, remove old code 1999-01-16 20:39:03 +00:00
bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the 
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
