Eliminate extraneous ttyalloc() calls.

Add missing splx(), per Jason.

57e61589e7
Fix two cases of handling stale page table information:
...
1. when reading the referenced/modified bits the TLB entry must be flushed
before reading the in-core version.
2. when wrapping up an entire segment in pmap_page_protect(), flush the PTPs
from the TLB to prevent a table-walking operation to pick up stale - or
possibly bogus - PTEs.
(hopefully I'll get a few of my hairs back now..)

CMP_PTE_USER_READ4M: check against PPROT_RWX_RWX; this is the canonical

stack protection (saves many excursions into trap.c on window underflows
as was the sole intention of the macro..).

prototype mmu_pagein4m() #if DEBUG is on.
1996-05-27 20:29:03 +00:00

No longer need to call mmu_pagein() through a pointer.
1996-05-27 01:13:02 +00:00
522c1d367a
mmu_pagein() is only useful on sun4/sun4c. For now, keep a `mmu_pagein4m()'
...
within `#ifdef DEBUG' for monitoring.
Push user windows to stack in pmap_extract() if we need to switch contexts.
1996-05-27 01:12:34 +00:00

espattach() requires DMA to be configured. For now, panic if it is not.

Allow all esp dma channels to be called `dma'.
1996-05-21 19:07:30 +00:00
dc7e7814d9
Remove the `espdma' special case; all `esp' related dma channels are now
...
called `dma' on all architectures. Note: `ledma' remains in place.
Also delete a couple of unneeded `needs-flag's in files.sparc.

We don't generally want to profile `genassym' (easy part of PR#2434).

0e4623e2f7
set the console struct winsize to the values given in the prom (sun4c/sun4m)
...
or the eeprom (sun4) when opening the console. (note: sun4 code untested
but jason claims it will `Just Work').
1996-05-19 13:00:43 +00:00

Add `_kernel_text' symbol for kvm_mkdb(8).

Check for `configuration parent' differently: compare against "sbus"
...
rather than "ledma".
1996-05-16 22:57:32 +00:00
b9f70e90d8
Add `flags' to the esp entries: disable disconnect & synch negotiation
...
by default until further notice.
1996-05-16 22:47:47 +00:00
e509f9aaeb
Change attributes of `dma', `espdma' and `ledma' (the attributes on the latter
...
two didn't seem to make much sense anyway..) to allow `esp' devices to be
attached to one of `sbus', `dma' and `espdma'.
Remove the wildcarded `espdma?' and `ledma?' attachments of `esp' and `le'
respectively, in favour of `dma?' and `lebuffer?' (but the latter is not
yet implemented), which seems to better match reality: additional SBus
SCSI/Lance boards call themselves `dma' and `lebuffer'.
1996-05-16 22:38:04 +00:00
3f1283a92f
Re-arrange code that looks for the esp driver to allow for the fact that
...
any "dma" device (i.e. not just "espdma") can have an OBP child. This is
the case with (at least some) SBus SCSI boards.
1996-05-16 21:45:35 +00:00
50e92fd71d
Use configuration file flags to disable reselection and/or sync negotiation,
...
on a per target basis (until the driver can sort things out on its own).
Test against "sbus" in stead of "espdma" to find out where in the
configuration tree we are: an esp can be the child of a "dma" on SBus
add-on boards.
