[IA64] Update Altix BTE error return status patch

2008-01-03T21:18:58Z

I neglected to send Tony the most recent version of the patch ("Fix Altix BTE error return status") applied as commit: 64135fa97ce016058f95345425a9ebd04ee1bd2a This patch gets it up to date. Without this patch on shub2, if there is no error xpcBteUnmappedError is returned instead of xpcSuccess. Signed-off-by: Russ Anderson (rja@sgi.com) Signed-off-by: Tony Luck

[IA64] Fix Altix BTE error return status

2007-12-19T19:19:19Z

The Altix shub2 BTE error detail bits are in a different location than on shub1. The current code does not take this into account resulting in all shub2 BTE failures mapping to "unknown". This patch reads the error detail bits from the proper location, so the correct BTE failure reason is returned for both shub1 and shub2. Signed-off-by: Russ Anderson Signed-off-by: Tony Luck

[IA64] fix possible XPC deadlock when disconnecting

2006-12-12T19:48:53Z

This patch eliminates a potential deadlock that is possible when XPC disconnects a channel to a partition that has gone down. This deadlock will occur if at least one of the kthreads created by XPC for the purpose of making callouts to the channel's registerer is detained in the registerer and will not be returning back to XPC until some registerer request occurs on the now downed partition. The potential for a deadlock is removed by ensuring that there always is a kthread available to make the channel disconnecting callout to the registerer.

[IA64-SGI] Silent data corruption caused by XPC V2.

2006-08-08T20:28:52Z

Jack Steiner identified a problem where XPC can cause a silent data corruption. On module load, the placement may cause the xpc_remote_copy_buffer to span two physical pages. DMA transfers are done to the start virtual address translated to physical. This patch changes the buffer from a statically allocated buffer to a kmalloc'd buffer. Dean Nelson reviewed this before posting. I have tested it in the configuration that was showing the memory corruption and verified it works. I also added a BUG_ON statement to help catch this if a similar situation is encountered. Signed-off-by: Robin Holt Signed-off-by: Dean Nelson Signed-off-by: Jack Steiner Signed-off-by: Tony Luck

[IA64] sparse cleanups

2006-08-02T23:03:44Z

Fix some sparse warnings on ia64. Large constants that should be long instead of int. Use NULL instead of 0. Add some missing __iomem casts. Replace a non-C99 structure assignment. Signed-off-by: Keith Owens Signed-off-by: Tony Luck

[IA64-SGI] enforce proper ordering of callouts by XPC

2006-02-15T21:35:03Z

Fix XPC so that it does not deliver any messages until the connected callout has returned, as well as, prevent the disconnected callout to occur before the disconnecting callout has returned. Signed-off-by: Dean Nelson Signed-off-by: Tony Luck
