Add some alternate spellings for ASIs.
...
Make sure ASI_PRIMARY_NOFAULT is always restored.
Garbage collect some old code.

Don't bother flushing cache lines for un-cached accesses.

Add the shorter version of block ASIs used by Sun.

Fix some 32-bit assembly code.

Comment out caxsa, it's not used. Avoids 32 bit compile errors.
2000-12-04 20:14:05 +00:00
a17d71cd4b
Fix register sheduling bug in st?a() routines and add casxa().

Tell gcc that stores clobber "memory". Probably makes no difference since
...
they should not be used to access normal memory anyway.

With these changes the kernel seems almost stable again.

More VM cleanup:
...
Move the cpu_info structure above the interrupt stack so it won't
get corrupted if the stack overflows.
Flush the D$ before and after all MMU bypass accesses since the
D$ latches all of those.

lda is unsigned, ldswa is signed. Fixes a 32-bit sign extension bug.
2000-06-20 18:06:12 +00:00
245619bad4
Have separate data and text segments, make text read-only.
2000-06-19 23:30:32 +00:00
d26027dd5b
Only use 32-bit addresses for all accesses that don't bypass the MMU.
...
Makes SBus work again.
2000-06-10 20:51:43 +00:00
6baca0c1ad
Fixup signed/unsigned issues so 32-bit addresses are not sign extended.
2000-06-08 17:43:24 +00:00

Add a couple of missing semi-colons.
2000-06-07 09:16:41 +00:00
03228642f7
Use all 64 address bits in ld*a()/st*a() macros so physical device addresses
...
work. (Also add some bus_space_*() debug hooks).

- IRSR_BUSY is bit 5 not bit 4.
...
- IRSR_MID(x) is &'d with 0x1f (5 bits) not 0xf.

mmm, missing return types make gcc unhappy.

186c3eba2b
Make pbrobeget() and probeset() work for 64-bit values as well. To do this
...
the arguments are changed so the address is first and the ASI second so we
can have the address in %o0:%o1 and not worry about unused registers.
Also a bit of copyright cleanup.
1999-06-05 21:58:16 +00:00

Fix some bugs in some more of those asm macros.
1999-05-31 00:13:16 +00:00
cd53dbd506
Re-write ASI load/stores to use full 64-bit addresses so we can use device
...
register addresses with MMU bypass ASIs.
1999-05-30 19:11:33 +00:00
56b080bed6
Fixup argument confusion to __asm() statements. long long is two registers
...
wide in 32-bit mode. Doh!.
1999-05-22 20:25:49 +00:00

Don't clobber any input regs in __asm statements.

Flush D$ on bypass accesses.

retire _LP64; use compiler provided __arch64__, but still defined _LP64 where we used to anyway.

It slices. It dices. It does everything except exec a sparc32_compat init.
