XXX: This should probably be MI in sys/lib/libsa.  After 1.4...

dbj 4717d3e130 fix typo allocating color framebuffer map. 1999-03-24 23:47:46 +00:00
simonb b4848d6b90 Code to initialise and add bootinfo records. 1999-03-24 23:47:37 +00:00
dbj a859ba2b23 Applied patches from Matt Debergalis <deberg@mit.edu>. 
These patches include:
  Added framebuffer mapping for color framebuffer to support color wscons
    which is coming soon.
  Renamed wskbdmap_mfii[ch] to wskbdmap_next[ch]
  Changed video to be white on black instead of black on white.
  Now handles and discards mouse interrupts.
  Video and keyboard is now working on mono machines.

bootinfo pointer is NULL, just return instead of trying to make use of it.

mrg ca5f9685bb clean up kernel/config files files for machVM lossage. 1999-03-24 06:06:09 +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.

jonb a50349ea32 Comment out options that are already the default... (I'm leaving them 
around as an example of what to change if needed.)

nisimura f719570f0a - Restore 'regdef.h' lost since last January. 1999-03-24 03:45:36 +00:00
mycroft 006ee23e99 Fix another problem is the modified bit emulation that caused double faults. 
We need to set the L2 type preemptively, as it may still be L2_INVAL if the
page had not been previously accessed.

simonb 0ba02670be New bootblock directory structure. 1999-03-24 02:07:22 +00:00
mycroft 11d7efb7ba Forgot a return instruction in the error case. 1999-03-24 01:51:56 +00:00
simonb 0074502b0a o Add bootinfo support by checking the fifth and sixth arguments for a 
magic number and a pointer to the bootinfo data.
   XXX: A bootinfo_magic record is not checked for at the moment, even
        though test bootblocks initialise the bootinfo data with one.

 o Use the bootinfo symtab information in preference to searching for a
   valid a.out exec header after _end for initialising DDB.
   XXX: Should retire a.out exec header support altogether.  Loosing the
        ability to load symbols from old bootblocks isn't much of a loss.
        After 1.4?

 o Add "booted kernel" machdep sysctl.

jonb 6c6ff861c6 put in compiler options to reduce object size by half 1999-03-23 23:02:14 +00:00
simonb 729eda4324 Define a bootinfo record and initial structures that the pmax will use. 
Modeled on i386 and bebox bootinfo.h.
 1999-03-23 22:53:02 +00:00
simonb aca34380db If on entry the stack is within 4kB of _start, don't reset the stack 
pointer to just underneath _start.  Allows bootblocks (or other kernel
calling programs) to pass more than 4 arguments if it sets up the stack
properly.

The 4kB figure may be overkill - on the pmax it only needs to be a dozen
of so bytes.
 1999-03-23 22:43:18 +00:00
simonb c9e3b47a0f Don't build anything while bootblocks are being updated. 1999-03-23 22:23:11 +00:00
simonb f93b8168c0 Include <machine/db_machdep.h> instead of <mips/db_machdep.h>. 1999-03-23 22:15:36 +00:00
simonb 41febd3a3c Move DB_{AOUT,ELF}_SYMBOLS (and DB_ELFSIZE) definition to port-specific 
db_machdep.h file.
 1999-03-23 22:07:06 +00:00
simonb 027594b1eb Add CPU_BOOTED_KERNEL to CTL_MACHDEP definition. 1999-03-23 22:04:01 +00:00
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)

bad 23d89d53f3 config(8) glue for the TCIC PCMCIA backend. 1999-03-23 20:07:39 +00:00
mycroft 1bb64b0636 __SWAP_BROKEN is no longer useful here. 1999-03-23 19:16:03 +00:00
mycroft 6bb727e736 Nuke some more code that was fetching PT_M and PT_H from pv_flags. 1999-03-23 18:39:38 +00:00
wrstuden 3c8e65b670 Oops. macppc doesn't use PCLK as a baud rate source. 1999-03-23 18:07:19 +00:00
mycroft 5f63cab877 The page and section fault handling paths are essentially identical, so 
combine them.  This also fixes a performance issue, in that we always
faulted pages twice in order to write them.
 1999-03-23 18:02:02 +00:00
wrstuden a7678930b4 Oops. mac68k does NOT use PCLK as a clock source, so don't enable it in 
the default channel setup.
 1999-03-23 17:55:03 +00:00
mycroft 79e56d3237 The ARM has the same copy-on-write bug as the i386 -- the write enable bit in 
PTEs is ignored when in kernel mode.  Hack around this just like we do on the
i386, by adding a prepass to copyout() to check for write permission on the
destination pages.
 1999-03-23 17:14:34 +00:00
minoura 87c8a7e347 u?vm_page_physload args are in page. 1999-03-23 15:55:43 +00:00
christos f36829e285 s/DEBUG/LDT_DEBUG/ This got too verbose when running Wine. 1999-03-23 15:48:19 +00:00
mycroft 8f3d31a32b More cleanup... 
* Don't bother pulling PT_M and PT_H bits from pv_flags; they can't ever be
  set there!
* Actually make pmap_clear_reference() do something useful.
* Also set the referenced bit (PT_H) when emulating a write fault.
 1999-03-23 13:52:48 +00:00
mycroft da99fe308e Repeat after me: 
If we're doing modified bit emulation, we must revoke write permission in
pmap_clear_modify().  This is non-negotiable.  I will revoke write permission
in pmap_clear_modify(), or suffer the wrath of a thousand bricks.
 1999-03-23 13:27:48 +00:00
mycroft 3c8512dbb5 We could not possibly have been updating the pv attributed correctly in 
pmap_enter(), so... make the obvious change.
 1999-03-23 12:30:45 +00:00
dbj c1824c37af more minor changes, mostly in minor tweaks to debuggin output. 
tweaks to handling dmasize != dmalen correctly.
changed minimum dma segment length for tail buffer.

gwr c19324e6bb Fix prototype mismatch. 1999-03-23 05:54:11 +00:00
minoura 86ecebe5e8 Move high-memory detect routine. 
This seems to fix the problem that it hangs up on 040turbo without
high-memory.
