of targets attached and access those simultaneously (like in a ccd(4) array).
We (now) allocate (somewhat arbitrarily) three per target.
Noticed by Marshall Midden.
- This driver supports the on-board mbus-based cgfourteen (sometimes referred
to as "SX") video hardware present on SS20-class machines.
- It does *not* support any of the SX acceleration features.
- It does support the 8-bit mode of the hardware, and looks to X like
a cgthree.
- It does support the cg6-style hardware cursor, even when running X in
cgthree emulation.
- It does support DPMS power-down of compatible displays on later-revision
cg14's.
- There is code to support the true color (32-bit) mode of the cg14 as
cg8 emulation, but it is disabled by default because it is most likely
broken. #define CG14_CG8 to turn it on.
The driver is not yet installed in the conf files, but I will do so
shortly...
NOTE: THESE FILES ARE NOW IDENTICAL TO THEIR ALPHA COUNTERPARTS.
The C preprocessor does the Right Thing when these files are built
on a SPARC. This makes it significantly easier to diff the two
versions (until a real MI 53c9x driver is done, hint hint).
would generate two interrupts, one real and one spurious. The solution
is to force a drain of the SBus->MBus write buffers after writing to the
lance to clear the interrupt. Thanks to Chris Torek for pointing out a much
easier way to do this than I had planned...
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
matic media detection on Sun4m machines which support multiple media
(UTP and AUI). New function lenocarrier() switches media type when called
if no link? flags are set.
Redefine link flags for Lance ethernet (le):
<none>: switch between media as needed to find carrier (autodetect)
Preference to whatever the PROM is using (AUI if not booted
from the network)
link0: use UTP port only
link1: use AUI port only
This allows Sun4m machines with dual media Lance ethernet adapters to
boot from the network on the UTP port.
