* [IA64-SGI] sn2 mutex conversionJes Sorensen2006-01-171-20/+14
| | | | | | | | | Migrate sn2 code to use mutex and completion events rather than semaphores. Signed-off-by: Jes Sorensen <jes@sgi.com> Acked-by: Dean Nelson <dcn@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64-SGI] move xpc.h to include/asm-ia64/sn (cleanup)Dean Nelson2006-01-131-2/+2
| | | | | | | | Cleanup a few items after moving xpc.h from arch/ia64/sn/kernel to include/asm-ia64/sn. Signed-off-by: Dean Nelson <dcn@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64-SGI] ensure XPC disengage request is processedDean Nelson2006-01-131-8/+12
| | | | | | | | | | | This patch fixes a problem in XPC disengage processing whereby it was not seeing the request to disengage from a remote partition, so the disengage wasn't happening. The disengagement is suppose to transpire during the time a XPC channel is disconnecting, and should be completed before the channel is declared to be disconnected.

* [IA64-SGI] fixes for XPC disengage and open/close protocolDean Nelson2005-10-251-35/+82
| | | | | | | | | This patch addresses a few issues with the open/close protocol that were revealed by the newly added disengage functionality combined with more extensive testing. Signed-off-by: Dean Nelson <dcn@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64-SGI] get XPC to cleanly disengage from remote memory referencesDean Nelson2005-09-061-101/+115
| | | | | | | | | | When XPC is being shutdown (i.e., rmmod, reboot) it doesn't ensure that other partitions with whom it was connected have completely disengaged from any attempt at cross-partition memory references. This can lead to MCAs in any of these other partitions when the partition is reset. Signed-off-by: Dean Nelson <dcn@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] fix call of smp_processor_id() by XPC whileDean Nelson2005-07-131-4/+4
| | | | | | | | | | | XPC calls smp_processor_id() twice from xpc_setup_infrastructure() with preemption enabled, which gets flagged if 'DEBUG_PREEMPT=y'. This patch replaces the two calls to smp_processor_id() by a single call to raw_smp_processor_id() since any CPU within the partition will do.

* [PATCH] gcc4 compile fix for recent ia64 xpc changesDave Jones2005-06-251-6/+6
| | | | | | | | | | Gcc4 doesn't like volatile casts as lvalues. Make the structure members volatile instead. Signed-off-by: Dave Jones <davej@redhat.com> Cc: "Luck, Tony" <tony.luck@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [IA64-SGI] SGI Altix cross partition functionality [2/3]Dean Nelson2005-05-031-0/+2297
This patch contains the communication module (XPC) for cross partition communication on a partitioned SGI Altix. Signed-off-by: Dean Nelson <dcn@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
