6290fed1b6 SVR4-related typo in previous. 1999-05-06 14:16:07 +00:00
scottr
0179750b00 Correct two more problems of the same type as in rev 1.21: use the length 
of the buffer you're copying from as the loop interator, not the length
of the buffer you're copying to.  Also, rewrite print_single() with
pointer instead of array operators.  Appears to correct some ADB-related
`hangs' during autoconfig.

a4adbf2f86 Move initialization of the iomem extent struct from mac68k_set_io_offset() 
to mac68k_init(), so that we're through frobbing the MMU in special ways
by the time we get there.  While it doesn't actually cause a problem with
the current structure of our initialization code, it probably would have
in the future.

009cda3fb2 Fix a problem with bounds_check_with_label(), noted by Greg Oster: we 
had been returning (-1) as an error instead of 0.  This is the result of
not keeping up with its i386 ancestor, which it was originally derived
from back in 1993.  Re-sync.

eb910c35ce From Ken'ichi Ishizaka: correct the calculation of the frame buffer 
offset by masking off garbage bits in the DAFB v7.  This has been
tested at all resolutions and common color depths on the LC47x.

b8073b401b Garbage-collect the VM_MBUF_SIZE constant. Instead, use the size 
(nmbclusters * mclbytes), so that the right amount of KVA space is
allocated if those variables are patched.

05b971dd5f in pmap_pageable(), rather than marking a PT page as not modified 
to trick the pagedaemon into freeing it later, just unmap the page
and free it immediately.  fixes PR 7337.

136972df3a Actually, the last change solved a different but related problem than 
the one mentioned in PR 7376.  By clearing the display in iteon()
instead, we can kill both birds with the same stone.

48ff49fee0 When attaching the ite console, clear the entire display rather than assuming 
that the emulator will do it for us.  (The emulator will only clear
full character-sized rows.)  Incidentally fixes PR 7376.

93768384ee Fix a bug in pmap_collect_pv(), even though nobody currently uses it: 
When we put a page on the collection list, we must subtract NPVPPG from the
total free count: one for each pv_entry that's free in that page, and one for
each free pv_entry in other pages that we're going to eat by moving the ones
in the page being collected.

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.
