linux-toradex.git/drivers/misc/sgi-xp/xp_uv.c, branch v3.2.68 Linux kernel for Apalis and Colibri modules x86: uv: update XPC to handle updated BIOS interface 2009-12-16T15:20:14+00:00 Robin Holt holt@sgi.com 2009-12-16T00:47:56+00:00 c2c9f115741453715d6b4da1cd2de65af8c7ad86 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.

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.
