2005-06-30[PATCH] ppc64: Replace custom locking code with a spinlockMichael Ellerman
The hvlpevent_queue (formally ItLpQueue) has a member called xInUseWord which is used for serialising access to the queue. Because it's a word (ie. 32 bit) there's a custom 32-bit version of test_and_set_bit() or thereabouts in ItLpQueue.c. The xInUseWord is not shared with they hypervisor, so we can replace it with a spinlock and remove the custom code. There is also another locking mechanism (ItLpQueueInProcess). This is redundant because it's only manipulated while the lock's held. Remove it.

2005-06-30[PATCH] ppc64: Simplify counting of lpevents, remove lpevent_count from pacaMichael Ellerman
Currently there's a per-cpu count of lpevents processed, a per-queue (ie. global) total count, and a count by event type. Replace all that with a count by event for each cpu. We only need to add it up int the proc code.

2005-06-30[PATCH] ppc64: Don't count number of events processed for callerMichael Ellerman
Currently we count the number of lpevents processed in 3 seperate places. One of these counters is never read, so just remove it. This means hvlpevent_queue_process() no longer needs to return the number of events processed.

2005-06-30[PATCH] ppc64: Rename ItLpQueue_* functions to hvlpevent_queue_*Michael Ellerman
Now that we've renamed the xItLpQueue structure, rename the functions that operate on it also. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-06-30[PATCH] ppc64: Rename xItLpQueue to hvlpevent_queueMichael Ellerman
The xItLpQueue is a queue of HvLpEvents that we're given by the Hypervisor. Rename xItLpQueue to hvlpevent_queue and make the type struct hvlpevent_queue.

2005-06-30[PATCH] ppc64: Make two ItLpQueue related functions staticMichael Ellerman
External parties don't need to use ItLpQueue_getNextLpEvent() or ItLpQueue_clearValid(), they're internal to ItLpQueue.c Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-06-30[PATCH] ppc64: Move initialisation of xItLpQueue into ItLpQueue.cMichael Ellerman
The xItLpQueue is initalised manually in iSeries_setup_arch(). Move this code into ItLpQueue.c for a cleaner separation. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-06-30[PATCH] ppc64: Don't pass the pointers to xItLpQueue aroundMichael Ellerman
Because there's only one ItLpQueue and we know where it is, ie. xItLpQueue, there's no point passing pointers to it it around all over the place.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
