91d8e018e2 Attach ite semantics to the appropriate grf device, instead of obio. 1996-08-05 01:26:31 +00:00
scottr
89f4fddbfe Add a way to tell grf_establish() that internal video doesn't actually 
occupy a slot.  This is necessary so that GRFIOCMAP can find the correct
physical address of the framebuffer.  Fixes P550, some LC models, and
perhaps the PB520.

08a2715e38 Test for serial console in adb_init() early, and abort if we're using it. 
Initiialize ROM vectors regardless of this so that the PRAM RTC read and
write work regardless of whether a serial console is in use.

cac1b831e9 - Simplify writes in sbc_drq_intr(). 
- When finished writing, if the SCSI bus has BSY asserted, write another
  byte to the SBC to ensure we get an interrupt.
- Unflag SCSI interrupts on the VIA whenever we clear the interrupts
  on the SBC itself.

d048582c60 New grf attachment code, mostly by Jason Thorpe with some cleanup by me. 
This will allow dt and X to work with a generic kernel, rather than
compiling different kernels that attach grf0 to a NuBus adapter or
internal video.

99e86ac209 Remove some gross hacks that were added due to interrupt grossness that 
has been partially fixed.  Also, add a new flag (which rearranges them
a bit, unfortunately) to use PDMA for polled transfers.

652b291390 - Rewrite scrollup(), scrolldown(), and clear_screen() to move/clear only 
visible screen memory.  This results in a considerable performance win
  at all depths.
- Correct clear_screen() behavior when clearing to the top and bottom of
  screen; start at current cursor position, not current cursor row.
- Add local prototypes, and other KNF.

6de4db6bbc Changed struct ifnet to have a pointer to the softc of the underlying 
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.

37163421a3 Prototype for -Wall -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized 
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped.  I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.

b50e8aab63 - Drop SCSI IRQ interrupts if we are already handling one. This works around 
a condition that occurs with some slow SCSI devices when they disconnect
  (e.g. the AppleCD 600), generating spurious selection interrupts.
- Reorganize the debugging code slightly.

18fd76201e We don't need to enforce the MAX_DMA_SIZE limit in dma_alloc();

2e936aa8ff - Remove several hacks that didn't do much but waste cycles. 
- Disable interrupt-driven PDMA when writing (use polled PDMA instead).
- Be more careful about when to flag a transfer as completed.

The result of these changes is that interrupt-driven PDMA works well
enough to bring the system up.
