sommerfeld aa195e816f Fix PR9240: comment above cpu_fork() out of synch with reality on most ports.
(comment change only, but was wrong for more than just i386).
2000-01-20 22:18:54 +00:00
danw 6c14ba0dba Fill in the alignment trap handler a bit: now it can fix unaligned
floating point loads and stores (to work around a gcc bug), but will
still cause a bus error on other sorts of unaligned accesses.

kleink 11e6c54cfc C99: Define a NAN macro in <math.h> which evaulates to a constant expression of
a single-precision quiet NaN; only to be defined on platforms that do support
this value.

thorpej 8fc6795a77 - Comment the BAT bits.
- Add defintions for the PowerPC 601 BATs.
- Change the BATU()/BATL() macros to be a bit more flexible; allow size,
  permissions, etc. to be specified.

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.

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).

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.
1999-03-26 23:41:25 +00:00
tsubai 82b3b0209f In copyin() and copyout(), clear the pcb_onfault variable in the EFAULT

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

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.

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.

thorpej cabecee13c Changes to support fork_kthread():
- cpu_set_kpc() now takes void *arg third argument, passed to the
  entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

no longer running on the dead proc's vmspace and stack).
