"evictions" and avoide calling pmap_pte_spill if there are no evictions
for the current pmap. Make the ISI execption use the default exception
code. Remove lots of dead stuff from trap_subr.
Make olink use TAILQ instead of LIST and be sorted with evicted entries
first and resident entries last. Make use of this knowledge to make
pmap_pte_spill do a fast exit.
intterupts. No more races between the two interrupt handlers, without any
locking, and the driver becomes a bit simpler too.
Use the last bit of the config flags to select between the first and the
second sbus interrupt level the firmware has assigned to us.
0x13 Function 0) after a read error. This is a requirement mentioned
in most BIOS documentation.
This answers PR 18591.
Incidentally, on the Soekris Engineering net45x1 single-board
computer, this fixes a bug where the bootloader corrupts the kernel
while loading it from certain varieties of CompactFlash card
(especially varieties identified by NetBSD as <TOSHIBA THNCF064MBA>).
When the read value is 0, reset the timer (don't wait till the next loop round to reset it)
Add a bit of debug to the calibration stuff to make sure its working ok.
- Use the PVO_CACHEABLE flag in the pvo as the One True Indicator of
the cacheable status of a mapping instead of peeking at the PTEH.
- Don't inline some of the larger routines, in an effort to appease
the somewhat buggy compiler.
- Fix some comments.
- Fix some casts.
- Add a bunch more debugging instrumentation.
- Move usr, sr, pc, and the branch-target registers to the top of
the listing so that it is no longer necessary to scroll through
64 integer registers to see them.
sparc64 does NOT appear to need a slicemap, so comment out that entire
section.
XXX: this program needs a rewrite. the argument handling is suboptimal.
that's coming next...
This argument has been previously unused, thus undetected due to void*
typing. Mmm, copy & paste. Note that sparc got it right though.
Many thanks to Valeriy E. Ushakov <uwe@netbsd.org> for debugging support.
