[PATCH] iSeries build with newer assemblers and compilers

2005-08-17T04:06:25Z

Paulus suggested that we put xLparMap in its own .c file so that we can generate a .s file to be included into head.S. This doesn't get around the problem of having it at a fixed address, but it makes it more palatable. It would be good if this could be included in 2.6.13 as it solves our build problems with various versions of binutils and gcc. In particular, it allows us to build an iSeries kernel on Debian unstable using their biarch compiler. This has been built and booted on iSeries and built for pSeries and g5.

[PATCH] ppc64: remove another fixed address constraint

2005-07-27T23:25:58Z

Presently the LparMap, one of the structures the kernel shares with the legacy iSeries hypervisor has a fixed offset address in head.S. This patch changes this so the LparMap is a normally initialized structure, without fixed address. This allows us to use macros to compute some of the values in the structure, which wasn't previously possible because the assembler always uses signed-% which gets the wrong answers for the computations in question. Unfortunately, a gcc bug means that doing this requires another structure (hvReleaseData) to be initialized in asm instead of C, but on the whole the result is cleaner than before.

[PATCH] ppc64: kill bitfields in ppc64 hash code

2005-07-13T18:25:25Z

This patch removes the use of bitfield types from the ppc64 hash table manipulation code. Signed-off-by: David Gibson Acked-by: Stephen Rothwell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ppc64: Replace custom locking code with a spinlock

2005-06-30T05:17:02Z

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. Signed-off-by: Michael Ellerman Acked-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] ppc64: Simplify counting of lpevents, remove lpevent_count from paca

2005-06-30T05:16:09Z

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. Signed-off-by: Michael Ellerman Acked-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] ppc64: Don't count number of events processed for caller

2005-06-30T05:15:53Z

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. Signed-off-by: Michael Ellerman Acked-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] ppc64: Rename ItLpQueue_* functions to hvlpevent_queue_*

2005-06-30T05:15:42Z

Now that we've renamed the xItLpQueue structure, rename the functions that operate on it also. Signed-off-by: Michael Ellerman Acked-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] ppc64: Rename xItLpQueue to hvlpevent_queue

2005-06-30T05:15:32Z

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. Signed-off-by: Michael Ellerman Acked-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] ppc64: Make two ItLpQueue related functions static

2005-06-30T05:08:56Z

External parties don't need to use ItLpQueue_getNextLpEvent() or ItLpQueue_clearValid(), they're internal to ItLpQueue.c Signed-off-by: Michael Ellerman Acked-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[PATCH] ppc64: Move initialisation of xItLpQueue into ItLpQueue.c

2005-06-30T05:08:27Z

The xItLpQueue is initalised manually in iSeries_setup_arch(). Move this code into ItLpQueue.c for a cleaner separation. Signed-off-by: Michael Ellerman Acked-by: Stephen Rothwell Signed-off-by: Paul Mackerras
