- Moved to x86/pci, so that EM64T systems running NetBSD/amd64 can use it.
- Added support for the TCO on ICH6 or newer chipsets, adapted from
FreeBSD.
- Added timecounter support for the power management timer, adapted from
OpenBSD.
- Plus some misc/cosmetic changes.
Thanks to yukonbob on irc@freenode for testing the TCO part on ICH4-M.
Tested by me with ICH7 too.
Features so far:
- use the blitter for scrolling and solid fills
- the usual wscons stuff, virtual consoles etc.
Things missing:
- /dev/fb* support
- XFree86 support although wsfb in 8bit should work
- hardware cursor support for X
- character drawing in hardware so we can run the blitter completely
asynchronous
- temporarily use the cpu's interrupt stack untill we are ready
to access non-OF-based mappings, then directly switch to the cpu's
idlelwp's uarea stack
- disable interrupts untill we are ready to call C code
rest of the kernel uses it to store the value of curlwp. Sam won't
recompile the HAL for us (fair enough), and we can't modify the HAL
to use another register because doing so could put us in breach of
the license (v. crappy). So, do a save/set/restore on %s7 in KernIntr()
and in the stubs that the HAL uses to call back into the kernel.
* Create the kernel thread in gre_clone_create() instead of trying
to create it in gre_ioctl(). (Thanks ad@ for suggesting it, and
pointing out that I can't kthread_create while I hold a spin
lock.) Run the thread always, but put it to sleep while the
gre(4) is not in UDP mode.
* Use sockaddr_in_init().
* Move some thread state off of the stack and into the softc.
* Extract subroutines gre_do_recv(), gre_do_send(), and gre_reconf()
from gre_thread1(), making the code more readable.
(Since "get the vote" doesn't tell much here about how a legislator
made the last vote to put this in effect.)
And so this calendar entry mentions U.S. also mention the 19th
Amendment to US Constitution.
