garbled | branches: 1.15.16; 1.15.18; 1.15.20;
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.

so that they can be used in a namespace-friendly way.
|
| 1.3 |
| 07-Oct-2002 |
bjh21 | branches: 1.3.8;
Minor tidy-up, mostly to improve readability. The SWP instruction is now
in its own little inline function, and this allows us to get rid of all the
automatic variables elsewhere. This subtly changes the semantics of
__cpu_simple_lock() such that the loop ends up one instruction longer, but
I'm not sure that's a particularly bad thing.
|
| 1.2 |
| 15-Nov-2001 |
thorpej | Implement __cpu_simple_lock*() primitives using the SWP insn. Note
this insn is available only on ARM arch v3 and later (and 2a). We
don't expect to be using these ops in the kernel on processors too
old to have SWP, and for userland uses (in e.g. a pthread library),
the kernel will simply have to trap and emulate the insn (it needs
to be "atomic", so a kernel trap of some sort will be necessary on
such platforms anyway).

Add the appropriate memory barrier before the lock is cleared in
__sync_lock_release_{1,2,4,8}. That is, all reads and write for the
inner shareability domain before the lock clear store.
Improve the membar_ops barriers - no need to use dsb and wait for
completion. Also, we only to act on the inner shareability domain.
Fix the barrier confusion. From Riastradh - thanks!.
