* Implement read for ulpt.
* If the device is not opened for reading, occasionally drain any
data the printer might have (but don't hammer the printer with reads).
* Lower the buffer size to one page.
The driver seems to work with more printers now.
its platform code is R530A. As such, the external video patches for
the R530 work for the '780. This gives a 640x480 video out (but only
the middle 240 pixels are used, to match the lcd resolution) on the
console and in X11.
>- Move PMAGB-BA and PMAG-JA (which I have) out of "may be incorrect" entries.
>- Put driver name "tfb" for PMAG-JA (which will appear in future pmax-wscons).
1. ABLE sets the l1pt to use domain 3 for it's entries (no idea why) so to
cover all bases when setting the domain before the change to the new L1pt
become a client of all domains.
2. It seems that we setup the kernel entries without any access permission.
(note not sure that this isn't a bug) And rely on the control bits
containing either ROM or SYST enable. which allows access to pages without
access permissions set. We actually enable SYST when we do the full detect
of the CPU, but we don't detect the CPU till after the L1pt switch, which
we never make it past. Fix this by explicitly enabling the SYST bit in the
control register. rather than relying on the firmware to have dont the right
thing.
removing assumptions that there are only two B channels and by
adding support for a varying number of channels.
Due to this, rename previously used isdn identified "bri" to "isdnif",
which better describes the current situation.
* auich_calibrate() assumes that the AC97 part is in its reset state. To
ensure this, call audio_attach_mi() after auich_calibrate().
* Explicitly support 12000Hz and 24000Hz. (Why is there a discrete list at
all?)
* Fix an obvious recording bug -- we were acking the wrong interrupt.
* Ensure that we don't get an interrupt during the AC97 speed probe by clearing
the "interrupt on completion" bit in the DMA setup.
