666c7f6fd4 interrupt counters for TurboChannel systems. 1996-06-05 00:30:48 +00:00

2d03e599c7 don't depend on being able to read the IMR. Apparently, it doesn't 
work (as documented in the DEC 3000/[3-9]00 System Programmer's Manual)
in some of the older 3000/500 systems.

c6dd609e7f gross hack to get around the fact that there are currently devices with 
common back-ends that live on multiple very-different busses (e.g. PCI and
TC), which need bus-specific DMA mapping support.  As a nice side effect,
this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.

6e6fc14f32 add tty_attach() calls where appropriate 1996-05-30 18:44:30 +00:00

5e29c383e2 add wbflush() calls in strategic places. These really shouldn't be 
here, and there should be a generic 'bus' interface to do memory
read/write barriers.

4145f89f54 TurboChannel bus_mem_* functions. bus_mem_{read,write}_8, and 
bus_mem_read_{1,2} are not yet supported for sparse space.

0307c36933 bus_io_* functions. These have no meaning on the TurboChannel, since 
it's a memory-mapped bus and has no I/O space.  They all are
fancy wrappers around panic().

7c1754fdff add a bit of clarafication in a comment, and change the interrupt 
handling code so that if a given interrupt is disabled (and therefore
can't have caused the actual I/O interrupt), its handler won't be
called even if its bit is set in the interrupt register.

49c46e1789 Preliminary CFB support. Does not work as machine's console (for two 
reasons: it won't attach as console, and there's currently no way to do
keyboard input on TC machines), and has no real RAMDAC (colormap, cursor,
etc.) support.  Digital UNIX does not support CFB frame buffers in the
Alpha, but they appear to work OK (with an appropriate monitor) in my
3000/300.

cb0eb158e7 fix the test for option slot interrupts. If a given interrupt is 
disabled (and therefore can't have caused the actual I/O interrupt),
don't try to call its handler even if its bit is set in the interrupt
register.

b65a5bbdfc preliminary SFB support. Does not work as machine's console (for two 
reasons: it won't attach as console, and there's currently no way to do
keyboard input on TC machines), and has no real RAMDAC (colormap,
cursor, etc.) support.

71c7924099 clean up clock handling: clock drivers are now seperate from the 
chip-independent clock code.  'clock' has been renamed 'mcclock'  'clock'
has been renamed 'mcclock' (since it's a driver for that particular
clock, and since eventually there may be another clock chip driver),
and now attaches via seperate match/attach functions to both TC and ISA.
This removes a whole lot of #ifdefs...

08607bc611 New device attachment scheme: 
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

deb4082f80 wholesale update from my NetBSD/Alpha source tree. Includes: 
Support for AXPpci CPUs,
	Support for AlphaStation 600 CPUs,
	new boot block structure, which requires an 'installboot'
	    program and works a lot like the NetBSD/sparc boot blocks.
