Update MIPS stack backtrace code to trace through locore functions,
...
traps, and interrupts The earlier (4.4bsd) code didn't do the first two, and
got the last one wrong. Also print some functions (e.g., trap handlers)
by name. Add hook to use something other than printf() as the output
function, e.g,. for kernel debugging.
Tested with the `native' toolset, but not ELF format kernels.
(i.e., unwinding the $GP register is not tested.)
The stack backtrace code that interprets and unwinds stackframes is still
opaque and stylistically awkward.
1995-04-29 21:10:31 +00:00

Add prototype (new-style) config for pmax. This doesn't yet work;
...
auto-configuration initialization code is missing. It uses "needs-count"
flags to come slightly close to what the old-style pmax source expects.
Perhaps autoconfig code can be lifted from the alpha port or volunteers
found to write some.

Fix performance bug in pmax MachFlushDCache(). Old code disabled icache
...
and wasn't unrolled. This code runs cached and unrolled, giving an order
of magnitude improvement in some cases (e.g., DMA-capable network devices).
In use at Stanford DSG since late January 1995.

Fix hardware interrupt-mask setup in the 5k/240 (3max)+ interrupt handler.
...
(A similar fix needs to be applied to the 3min and xine handlers.
This fixes a long-standing problem when booting with a card that
wants to interrupt (e.g., a network interface) would have interrupts
enabled before a handler was set up.
Add interrupt-counting code to model-independent interrupt handler,
and 3max (5k/200) and 3max+ (5k/240) md handlers, for vmstat -i.
Similar changes for 3min and xine are obvious but not done.
Add code for 5k/240 to read, and latch, the current value of the
IOASIC bus-cycle counter at each timer interrupt. The latched
counter is needed to accurately interpolate the bus-cycle counter value
as a high-resolution clock.

- Remove cpuspeed

when it is 'binpatched' with a value that is not a multiple of the
page size.
