nisimura e37ce1c5b6 Make spl(9) rountines target port dependent. delay() is also port
dependent anticipating a target with high resolution timer available
for on-the-fly re-programming.  Enum decstation_t was removed from MI
trap.c.

thorpej d47ea67c1f Define one page free list, and put all pages on it. 1998-07-08 04:43:18 +00:00
cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

thorpej 691e8af708 Add a "virtual address" private member to the pmax bus_dma_segment_t, for
use in R4000 cache flush operations in bus_dmamap_sync().

thorpej 7a9c58e1b1 Complete from-scratch rewrite of the DECstation bus.h, brining it
up-to-date with the current API, and implementing preliminary
support for bus_dma.

thorpej b6fca1a9c8 The line between "family" and "model" are ... very fuzzy on the DECstation.
So, don't bother.

jonathan b40a3c98f5 Use an MD name for the FPU-interrupt mask, as in PR # 4399.
mips-based Sony news wire the FPU to hard-interrupt 3, rather than 5
as recommended in Kane.

jonathan 6975dc93a9 Split sys/arch/pmaxpmax/{machdep.c,trap.c} as suggested by Jason Thorpe:
* add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h
   (based on Alpha cpuconf.[ch], with a namechange to avoid clashes with
   support for  models of MIPS cpus. They  differ more than Alphas).

 * For each supported model of DECstation, create a separate file
   with the support for that model.  Use model codenames, since
   support is really baseboard-specific and CPU daugherboards can change.
   Move code from machdep.c and pmax_trap.c,
   Add sysconf (nee "cpuconf") support.

 * Rename model-specific functions to match sysconf names.

 * Clean up autoconf.c.  Use platform callbacks.

 * Retire pmax_trap.c.

Leaves  I/O bus configuration and console configuration untouched.

jonathan a03a434f1b * Use ANSI-clean names for host-specific byte-order definition
(_BYTE_ORDER, _BIG_ENDIAN, _LITTLE_ENDIAN).
  Define old names from the ANSI ones if not _POSIX_SOURCE.
* Define _QUAD_HIGHWORD and _QUAD_LOWWORD properly when
  _BYTE_ORDER == _BIG_ENDIAN.

possible. Pointed out by Bernd Ernesti.

leo d4713d24c2 Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

jonathan 1f44934407 * Change Sprite MACH_xxx prefix to MIPS_xxx.
* Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the

jonathan 2d10220f8f Yet more mips1/mips3 merging:

   * Move definitions of CLKF_BASEPRI, CLKF_USERMODE to mips/include/cpu.
   * Delete duplicate definitions in pica/include/cpu.h, pmax/include/cpu.h.

pmax/include/psl.h would go away completely if it wasn't stil required
by compat/common/kern_exit_43.c.

jonathan c66d855eb2 Configure pmax elf_machdep.h as little-endian elf. 1996-12-17 03:45:05 +00:00
cgd 96acdadef7 First step inn removing config_scan() and the hacks that gave devices
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.

jonathan 6ac1fdec40 Merge mips1 and mips3 pte/pmap code, pass 0;
* Move mips-I pte (TLBlo) definitions from pmax/include/pte.h
      to mips/include/mips1_pte.h

    * Move mips-III pte (TLBlo) definitions from  pica/include/pte.h
      to mips/include/mips3_pte.h

    * Add new mips/include/pte.h, which includes exactly one of
      mips1_pte.h or mips3_pte.h (which still have namespace collisions),
      depending on "options MIPS1" or "options MIPS3". (hack).
      Move soft kvtopte(), ptetovk() definitions to mips/include/pte.h

    * Add macro PTE_TO_PADDR() to hide the different hardware TLB formats
      when mapping from pte to physical address.

   * Add macro PTE_READONLY() to hide lack of SW read-only bit in mips-III
     tlb. (mips1 pmap uses a sw bit in the PTE, mips3 looks up RO bit in
     the kernel pmap.)

   * Use macros (not direct TLB frobbing) in mips/trap.c, to make it
     mips-1/mips-III indepenndet.

    * Change {pmax,pica}/include/pte.h to just do #include <mips/pte.h>.
