Peter Wemm	3db6450423	Reconfigure the runq macros to use the 64 bit ffs/bsf routines instead ... of doing a loop and taking two 32 bit passes at the runqueue bits. All the 64 bit platforms should probably do this since there are 64 run queues. Approved by: re (scottl)	2003-12-06 23:24:18 +00:00
Peter Wemm	2f9267ec23	Move the "- 1" into the RQB_FFS(mask) macro itself so that ... implementations can provide a base zero ffs function if they wish. This changes #define RQB_FFS(mask) (ffs64(mask)) foo = RQB_FFS(mask) - 1; to #define RQB_FFS(mask) (ffs64(mask) - 1) foo = RQB_FFS(mask); On some platforms we can get the "- 1" for free, eg: those that use the C code for ffs64().

Jake Burkholder	d2ac231616	Make the run queue parameters machine dependent. Optimize 64 bit ... architectures by using a 64 bit word for the bit array which keeps track of non-empty queues. Reviewed by: peter	2002-05-25 01:12:23 +00:00
