x86: uv: update XPC to handle updated BIOS interface

2009-12-16T15:20:14+00:00

The UV BIOS has moved the location of some of their pointers to the "partition reserved page" from memory into a uv hub MMR. The GRU does not support bcopy operations from MMR space so we need to special case the MMR addresses using VLOAD operations. Additionally, the BIOS call for registering a message queue watchlist has removed the 'blade' value and eliminated the structure that was being passed in. This is also reflected in this patch.

sgi-xp: xpc needs to pass the physical address, not virtual

2008-12-16T22:04:24+00:00

Impact: fix crash xpc needs to pass the physical address, not virtual. Testing uncovered this problem. The virtual address happens to work most of the time due to the way bios was masking off the node bits. Passing the physical address makes it work all of the time.
