thorpej f0449fd933 - Rename cpu_use_fxsave to i386_use_fxsave.
- If we detect SSE/SSE2 support in the CPU, enable SSE exceptions
  and set i386_has_{sse,sse2} as appropriate.
- Expose i386_use_fxsave and i386_has_{sse,sse2} through sysctl
  as machdep.{osfsxr,sse,sse2}.

jdolecek 2b7d2123cd Make console polling (cnpollc/cngetc) work on IBM PS/2 keyboard controller
using level triggered interrupts, which livelocks calling intr routine
if the data register is not read in the interrupt routine, as it's case
when polling after interrupts are enabled during boot.

Block all interrupts when polling for keypress, and modify intr routine
to read and store value from data register. The latter one is to avoid
losing a keypress when one would manage to press a key when kernel is
not in spl-guarded code section.

Tested with classic pccons, 'pcconskbd at pckbc' and 'pckbd at pckbc'
configurations, on i386.

jdolecek f6af05f407 Back the last revision off, upon Bill Sommerfeld's request 2001-06-02 00:46:00 +00:00
jdolecek 5dbe622e77 When polling, raise priority level to tty, to block keyboard interrupts
when the system is "warm", i.e. interrupts are not blocked anymore.
This seems to be necessary on my PS/2 Model 70 keyboard - without this,
system ends up in endless loop calling the keyboard intr routine if a key
is pressed when polling. This _may_ be just specific to level-triggered
interrupts PS/2 MCA uses, though it's more likely it's just the way the
particular keyboard controller works.

Discussed on tech-kern@.

scw 2963ff5c58 Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point
in each tty driver to indirect through it.

This allows tty line-disciplines to handle poll(2) system calls.

jdolecek 7c9c35e3e7 Move the inclusion of 'mca.h' so that it doesn't depend on pcppi. The clock
interrupts are properly reset on PS/2 now.

Handle the slighly different PS/2 CMOS layout and get/set century
byte as appropriate. The check for valid CMOS CRC checksum is not implemented
yet; I don't currently know algorithm they use.

The info about PS/2 CMOS was taken from the Padgett Peterson's
x86/MSDOS Interrupt List, release 60.

thorpej 8b3fc18a1f Generic soft interrupt implementation for NetBSD/i386. This could
probably be tuned somewhat, but this is a stop-gap measure to hold
us until Bill Sommerfeld's new interrupt code comes in from the
MP branch.

cgd a5c13f9ad4 Kwality control:
* put #includes of opt headers and headers to get protos used by
  net/netisr_dispatch.h in net/netisr.h (if !defined(_LOCORE)) (rather than
  in netisr_dispatch.h itself, and potentially nowhere, respectively).
* require netisr.h to be included before netisr_dispatch.h.
* minor additional cleanup of both netisr.h and netisr_dispatch.h.
* clean up uses to remove now-unnecessary header file inclusions, and
  local prototypes of the fns.
* convert netisr dispatch implementations which didn't use
  netisr_dispatch.h (pc532) to use it.

simonb 889c658b5b Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

sommerfeld bcf02ec8ff If rnd is configured into the kernel, do rnd(4) entropy collection
from devices connected to pckbc:
 - Do actual sample collection in pckbc.
 - Add rndsource_element_t to the slot data.
 - Change pckbc_set_inputhandler() to take an additional argument,
the name of the device, which is (eventually) passed into
rnd_attach_source() to identify the source.
 - Change callers of pckbc_set_inputhander() appropriately.

thorpej b667a5a357 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
