- video base register value brings different scanline starting address
of framebuffer depending on VRAM chip column size.
many other issues left unsolved.
- text rendered in incorrect colours.
- acceleration codes should be reimplemented from scratch.
the link level name for the interface (ifp->if_sadl) is allocated
before ifp->if_addrlen is initialized, which could lead to allocating
too little space for the link level address.
Do this by splitting allocation of the link level name out of
if_attach() and into if_alloc_sadl(), which is normally called
by functions like ether_ifattach(). Network interfaces which
don't have a link-specific attach routine must call if_alloc_sadl()
themselves (example: gif).
Link level names are freed by if_free_sadl(), which can be called
from e.g. ether_ifdetach(). Drivers never need call if_free_sadl()
themselves as if_detach() will do it if it is not already done.
While here, add the ability to pass an AF_LINK address to
SIOCSIFADDR in ether_ioctl() (this is what caused me to notice
the problem that the above fixes).
than the preivous code. It can show readable characters on screen.
Tested only with 32bpp model of PMAGD opion card. Need more work for 8bpp.
- 2D accelleration will be revamped to ultilize SFBplus features.
- there seems much mulfunctionness in 32bpp codes of /sys/dev/rasops/.
Need to rectify every corners.
and place the definition in <machine/types.h>. This can now be used
as a flag to indicate whether or not <machine/intr.h> can be included
to get the generic soft interrupt API.
Paul Kranenburg, many thanks !): the control register I/O is 4 byte long
although only one is used, but the control register is at offset 2, and not
0 as expected by IC code. Use bus_space_subregion() to get a handle which
points to the control register, and is one byte long.
cause interrupts). This works around a problem on sparc64, where
interrupts without installed handler seem to cause heavy lossage (and
interrupts are already enabled at this stage of autoconfiguration).
