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.
flexibility in turn; this renderer is 2B stroke (less than 16 pixel
width) font only. If 1B stroke (less than 8 pixel width) font is
ever supported, the font data should be converted into 2B stroke
during font initialization process. 'wsfont_realize()' is to be
proposed in order to have 'CPU and/or accelerator hardware friendly'
format to squeeze maxinum performance.
configured, but after all adapters have been configured. When multiple
adapters are present, only the last configured adapter could be matched
to the boot device slot. The adapter attach routines now check if that
adapter slot matches the boot device slot and saves the softc pointer
for that controller. Then when the disks are configured, dk_establish()
matches the appropriate controller.
-don't set capabilities at compile time
-since our accelerated putchar() doesn't underline, don't claim so
-remove bogus character range check - fonts are not limited to ASCII
-use rasops_unpack_attr() instead of relying on rasops internals
byte) boundaries don't work correctly. Make use of the SDR0/SDR1 registers
to adjust the buffer alignment when starting the DMA transfer. Block device
I/O done by the filesystems will usually be aligned correctly, but character
device I/O may not be aligned correctly. This should fix the problems with
dump(8) failing randomly on DECstations.
- Nuke tc_badaddr() check from asc_tc because the existency check is already
done for real TC devices.
- Nuke tc_badaddr() check from asc_ioasic because it is a builtin device
found in all of IOASIC DECstations.
is found not fully upward compatible to its predecessor. sfbp.c is now
under development.
- Reduce copycols() malfunction, but has still lot of troubles.
to be corrected. Text drawing is now improved significantly, but;
cursor is drawn incorrectly, copycols() trashes a screen, 'standout
(\033[7m)' results in lines reversed entirely until '\033[0m', and
possibly more issues. Not multi-colour, 8bpp only this moment. Costly
write memory barrier instrunctions should be eliminated using framebuffer
address aliasing technique for NetBSD/alpha.
