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

2006-08-08T20:28:52+00:00

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-SGI] ensure XPC disengage request is processed

2006-01-13T18:16:36+00:00

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] utilize notify_die() for XPC disengage

2005-11-10T19:32:41+00:00

XPC (as in arch/ia64/sn/kernel/xp*) has a need to notify other partitions (SGI Altix) whenever a partition is going down in order to get them to disengage from accessing the halting partition's memory. If this is not done before the reset of the hardware, the other partitions can find themselves encountering MCAs that bring them down. Signed-off-by: Dean Nelson Signed-off-by: Tony Luck
