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.

drochner 76fa1751fe Add a macro to check for sufficient pointer alignment in bus.h context, 
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

jonathan 69d2d27c1b Use bus_space tags and handles, embedded in MD hooks AM7930_{READ_WRITE}_REG 
to handle MD delay and bus padding. Tested on sparc2 by David Brownlee.

Should use regmaps, but that breaks sparc pDMA assembly code.

chs 31ef6fbb8d add RODATA(), which is like ENTRY() but without the _PROF_PROLOGUE. 1999-02-24 16:02:19 +00:00
kristerw 871ac39c21 The recent simplification of the lint version of the va_arg macro broke 
linting of vfprintf.c, where va_arg is used as
   *va_arg(ap, quad_t *) = ret;
Make the macro slightly more complicated...

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.

oster c74d32c5fc Updating of bdev's and cdev's to support RAIDframe. 1998-11-13 04:47:03 +00:00
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.

chs 61458d7dfa LOCKDEBUG enhancements for non-MP: 
keep a list of locked locks.
use this to print where the lock was locked
when we either go to sleep with a lock held
or try to free a locked lock.
