Re-write of CPU/MMU detection code.
...
Use a table driven classification based on CPU and MMU implementation/version
fields. Each CPU class or module defines a collection of routines that
implement CPU or MMU specific operations that can collect detailed setup
information.
All information is collected in a `cpu_softc' structure provided by the
auto-configuration code. However, in the interest of SMP support this
structure is located at a fixed virtual address identified by the
symbol `cpuinfo'. The `boot' CPU currently uses the the physical page(s) at
address 0x2000 for its cpuinfo. Consequently, the fixed virtual address
will be `KERNBASE+0x2000'.
The cache flush routines for several systems (sun4/4c vs. sun4m;
virtual vs. physical tags) have been factored out. Function pointers
to an appropriate set are located in `cpuinfo'. The former global
`cacheinfo' structure is now also a part of `cpuinfo'. Because of the
fixed virtual address of `cpuinfo' no extra performance penalties
are incurred by this move. In multi-architecture kernels, there's
no longer the need for run-time `cputyp' tests in this part of the system.
1997-03-11 00:44:00 +00:00
8d2c03c810
Replace `cputyp' run-time tests by inserting multiple branches and NOPing
...
some at startup depending on architecture.
Use `get_faultstatus' field in `cpuinfo' (initialized in cpu.c) to branch
to CPU/MMU specific fault status reading stubs on memory fault traps.
Remove code top map the Interrupt Enable register on sun4/sun4c. Its VA
has moved to a high location and is now mapped in autoconf.c after
pmap has initialized. Note: this renders NMIs during bootstrap() fatal
(maybe loading %tbr should be deferred).

the copy/zero operations were done via uncached memory accesses, which

to be copied or generated.

Add cgfourteen driver as device "cgfourteen"
1996-09-30 22:43:38 +00:00
19b3f7f50b
Initial commit of cg14 framebuffer driver for Sun4m SPARCs.
...
- 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...

Change attributes of `dma', `espdma' and `ledma' (the attributes on the latter
...
two didn't seem to make much sense anyway..) to allow `esp' devices to be
attached to one of `sbus', `dma' and `espdma'.
Remove the wildcarded `espdma?' and `ledma?' attachments of `esp' and `le'
respectively, in favour of `dma?' and `lebuffer?' (but the latter is not
yet implemented), which seems to better match reality: additional SBus
SCSI/Lance boards call themselves `dma' and `lebuffer'.

Re-arrange code that looks for the esp driver to allow for the fact that

any "dma" device (i.e. not just "espdma") can have an OBP child. This is

Use configuration file flags to disable reselection and/or sync negotiation,
...
on a per target basis (until the driver can sort things out on its own).
Test against "sbus" in stead of "espdma" to find out where in the
configuration tree we are: an esp can be the child of a "dma" on SBus
add-on boards.
