6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be 
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).

9dae8945ef In kvm_uncache(), turn off the PTE cache bit even after calling 
pv_changepte(). Reason: the managed() macro does not take into
account the gap in the managed pages range that may have been introduced
by the page table allocation in bootstrap().

95bdb660ed Simple screen attribute handling for wscons. 
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.

-initialize errno to 0 before receiving
-minimal allowed packet size is 4 (empty data packet)
-Be nice to the TFTP server - tell it that the transfer is finished
  (additinal ACK at EOF, ERROR otherwise). Otherwise, it will linger
  around and retransmit. This can be left out (TFTP_NOTERMINATE) if we
  are really short on space.

0624060713 Rework PCI interrupt mapping on the EB164 systype. Rather than computing 
interrupt routing directly, use the interrupt routing information provided
in the PCI "line" register.  The previous scheme did not work properly on
AlphaPC 164SXs.  Also, be silent about the fact that 0/8/x does not
have its interrupt mapped; this is to be expected on the 164SX (this is
the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions
1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).

469658d533 - Allow all valid SCSI id's to work on the SII and first two ASC 
controllers (including SCSI id 7 on the 2100/3100).

- Move disk and tape config for the second ASC controller from the GENERIC
  config file to scsi.pmax so all configurations can use the second
  controller.

8c45fef21f When changing the mapping on a page, remove the previous mapping if 
there is one.  The Mach VM system seems to take care of this, so it
hasn't knowingly caused a problem.  UVM does change mappings without
removing the current mapping, and will pmap_page_protect() hangs
if pmap_enter() doesn't remove the previous mapping.

e615541de9 Maintain far more complete state in the PV lists on the cacheability of pages, 
using separate flag bits for mappings that were requested to be not
cacheable and uncacheable pages due to incongruent aliases.

This avoids inadvertently turning on the cache-enable bits when removing
one of multiple virtual address mappings to the same page. Reading
from /dev/mem could do this to arbitrary pages.

7c867905c5 Major overhaul of pagetable handing. 
Page tables no longer occupy space in the processes vm_map. This
  means that page tables can now be allocated from pmap_enter() when the
  first entry is made in the page table rather than relying on taking
  a section fault and faulting in a page table. This also lowers
  the overheads in creating and deleting page tables and simplfies
  cpu_fork().
  A result of this change is that problems with mapping zero page and
  an associated pagetable when execing from a shared vm_map disappear
  fixing PR5178.

33b4b52949 Define the prototypes for rtc_read() and rtc_write() here rather than 
in machine/rtc.h
Update the rtc_read() and rtc_write() functions to take a private pointer
as the first argument (currently unused).

1f5455aaaf Update the softc to hold the rtc_{write,write}() argument and update 
the function pointer prototypes.
Pass the rtc_arg field as the first parameter when calling the todclock
rtc_{read,write} function pointers.

c4f9d5c4b0 Add a rtc argument field to the todclock_attach_args structure. 
Update the ta_rtc_{read,write}() functions in the todclock_attach_args
structure to take an argument attach time defined argument field as the
first argument.

53c671e26c Add locore assembler functions to read mips3 cycle counter, and 
read and write compare register (controls cycle-driven periodic interrupt).

Use cycle counter for microsecond time on mips3, but for now only on
3min motherboards (5000/150).  the MAXINE baseboard microsecond
counter is more stable and I don't ave no 5000/260 to test.

XXX clkread() is a mess, it should be rewritten.
XXX should add nanotime() to give inkernel nanosecond resolution,
    and then microtime() reworked to use nanotime().

4ea6444493 Decsystem 5100 (aka mipsmate aka kn230) support: 
* dec_5100.c: sysconf, interrupt, and  motherboard (drain writebuffer)
   support for 5100.
 * support for hardware kludge in 5100: sii DMA buffer is hardware
   padded to alternate 32-bit words, not alternating 16-bit  halfwords.
 * 5100 has no framebuffer, console is wired to serial port 0.

With ibus support, boots as far as exec'ing init, and hangs.

PCI IDE compat interrupts.  Note that this function is optional, and
platform-specific code may initialize the pointer to NULL.
