compiled-in or runtime loaded fonts,
keep font pointers in a LRU queue and load into the adapter on demand,
so we can have more fonts in use than physical font slots
CAUTION: font loading through the wsdisplay device directly into the
adapter doesn't work anymore!
in how interrupts are down- the 23XX has not only a different place to check
for an interrupt, but unlike all other QLogic cards, you have to read the
status as a 32 bit word- not 16 bit words. Rather than have device specific
functions as called from the core module (in isp_intr), it makes more sense
to have the platform/bus modules do the gruntwork of splitting out the
isr, semaphore register and the first outgoing mailbox register (if needed)
*prior* to calling isp_intr (if calling isp_intr is necessary at all).
little-endian byte-order. This should work out to be a no-op
for LE systems, and allows BE systems to use the board.
Tested on PPC, reviewed by Dante.
NOTE: The board/microcode does have a BIG_ENDIAN mode of operation,
but it's not well-documented. That might be interesting to investigate
at some point in the future, though.
- cominit() is local to com.c, remove prototype from comvar.h.
- Don't prototype comstop(), cdev_decl(com) does this.
- Don't use a block device switch table declaration(!).
- No need to include "com.h".
using level triggered interrupts, which livelocks calling intr routine
if the data register is not read in the interrupt routine, as it's case
when polling after interrupts are enabled during boot.
Block all interrupts when polling for keypress, and modify intr routine
to read and store value from data register. The latter one is to avoid
losing a keypress when one would manage to press a key when kernel is
not in spl-guarded code section.
Tested with classic pccons, 'pcconskbd at pckbc' and 'pckbd at pckbc'
configurations, on i386.
- minor code cleanups
- rename some functions for better consistensy/clarity
- consolidate extended message generation into new function
- a couple of minor code clarifications to eliminate extra return
statements and make absolutely sure actscb is NULL during a reselect
tag handy and we are going to need more of it in pckbc_poll_data1() soon,
change pckbc_poll_data1() to accept it as first arg. iot, ioh_d, ioh_c are
no longer passed separately. Use fabricated pckbc tag for calls from
arch/arc/jazz/pckbc_jazzio.c and dev/isa/pckbc_isa.c.
