mips: Brush up __cpu_simple_lock.

- Eradicate last vestiges of mb_* barriers.

- In __cpu_simple_lock_init, omit needless barrier.  It is the
  caller's responsibility to ensure __cpu_simple_lock_init happens
  before other operations on it anyway, so there was never any need
  for a barrier here.

- In __cpu_simple_lock_try, leave comments about memory ordering
  guarantees of the kernel's _atomic_cas_uint, which are inexplicably
  different from the non-underscored atomic_cas_uint.

- In __cpu_simple_unlock, use membar_exit instead of mb_memory, and do
  it unconditionally.

  This ensures that in __cpu_simple_lock/.../__cpu_simple_unlock, all
  memory operations in the ellipsis happen before the store that
  releases the lock.

  - On Octeon, the barrier was omitted altogether, which is a bug --
    it needs to be there or else there is no happens-before relation
    and whoever takes the lock next might see stale values stored or
    even stomp over the unlocking CPU's delayed loads.

  - On non-Octeon, the mb_memory was sync.  Using membar_exit
    preserves this.

  XXX On Octeon, membar_exit only issues syncw -- this seems wrong,
  only store-before-store and not load/store-before-store, unless the
  CNMIPS architecture guarantees it is sufficient here like
  SPARCv8/v9 PSO (`Partial Store Order').

- Leave an essay with citations about why we have an apparently
  pointless syncw _after_ releasing a lock, to work around a design
  bug^W^Wquirk in cnmips which sometimes buffers stores for hundreds
  of thousands of cycles for fun unless you issue syncw.

Use userspace version unless _HARDKERNEL.  Otherwise we use atomic
cas to implement spinlocks and spinlocks to implement atomic cas....
which might suck.

Since the userspace version uses ll/sc, which doesn't exist on
R2000/R3000, rump will not work on those platforms.  *snif* (well,
pthread in general AFAICT).

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

machines.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Let each platform typedef the new __cpu_simple_lock_t, which should
be the most efficient type used for the atomic operations in the
simplelock structure, and should also be __volatile.

Revision 1.1 / (download) - annotate - [select for diffs], Sat Apr 29 03:31:51 2000 UTC (22 years, 9 months ago) by thorpej
Branch: MAIN

Require that each each MACHINE/MACHINE_ARCH supply a lock.h.  This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
