ad feb4783fdf Replace use of CACHE_LINE_SIZE in some obvious places. 2008-03-27 18:30:15 +00:00
martin d8788e7fd7 Use cpu index instead of the machine dependend, not very expressive 
cpuid when naming user-visible kernel entities.

ad 598ab03ad0 Match the docs: MUTEX_DRIVER/SPIN are now only for porting code written 
for Solaris.

yamt 69aa06cd40 don't bother to set thread's priority by ourselves, 
as kthread_create does it for us now.  from Andrew Doran.

yamt e3fe8e011e - don't assume the order of cpus in a CPU_INFO_FOREACH loop. 
- remove unused structure members.
- simplify.

ad 5b2aca96b9 Current convention is to name/number objects after ci->ci_cpuid, so do 
that when creating the kthreads. We may want to change this.

rmind c8c024369c Improve per-CPU support for the workqueue(9): 
- Make structures CPU-cache friendly, as suggested and explained
   by Andrew Doran.  CACHE_LINE_SIZE definition is invented.
 - Use current CPU if NULL is passed to the workqueue_enqueue().
 - Implemented MI CPU index, which could be used as an index of array.
   Removed linked-lists usage for work queues.

The roundup2() function avoids division, but works only with power of 2.

rmind 8c2097ad8d Make MP parts friendly with various ports (especially UP): 
- #ifdef code parts, which uses CPU_INFO_FOREACH/CPU_INFO_ITERATOR
 - use ci_cpuid only in MP case
 - include machine/cpu.h

rmind 20bbb87e34 Implementation of per-CPU work-queues support for workqueue(9) interface. 
WQ_PERCPU flag for workqueue and additional argument for workqueue_enqueue()
to assign a CPU might be used. Notes:
 - For now, the list is used for workqueue_queue, which is non-optimal,
   and will be changed with array, where index would be CPU ID.
 - The data structures should be changed to be cache-friendly.
