Benno Rice	dfc02c301d	Make atomic_cmpset_32 correctly return 0 on failure.	2002-02-24 23:31:49 +00:00
Benno Rice	abc5579e8c	Fix the atomic_*_32 operations. These were written before I had the ability ... to test them properly and before I had a working knowledge of GCC asm constraints.	2001-06-27 12:17:23 +00:00
Benno Rice	7a0e745f1a	Don't initialise ret in atomic_cmpset_32. ... Add more synchronisation.	2001-06-26 13:54:17 +00:00
Benno Rice	e2d53d7c4a	Fix asm constraints for atomic_cmpset_32. This fix may also be needed ... elsewhere.	2001-06-24 06:36:28 +00:00
Benno Rice	d27f1d4c12	This commit (along with one pending in sys/dev/ofw and one in sys/conf) give ... us our first minimal glimpse of PowerPC support. With this code we can get to the "mountroot>" prompt on my Apple iMac. We can't get any further due to lack of clock and interrupt handling, among other things. This does however mean that pmap and VM are initialising. We're fairly dependant on OpenFirmware at this point, but I hope to add support for other classes of firmware at a later stage.

Benno Rice	199a2415c0	PowerPC atomic operation functions. ... Some of these are dependant on an inline function (powerpc_mb()) that is yet to come. Reviewed by: obrien	2001-01-07 03:46:01 +00:00
David E. O'Brien	b5073b49d9	Shells for the atomic operations FreeBSD needs. ... This is just waiting for a budding PowerPC ASM guy to fill in the blanks.	2001-01-01 23:06:59 +00:00
