2020-10-07x86/platform/uv: Add and decode Arch Type in UVsystabMike Travis1-3/+13
When the UV BIOS starts the kernel it passes the UVsystab info struct to the kernel which contains information elements more specific than ACPI, and generally pertinent only to the MMRs. These are read only fields so information is passed one way only. A new field starting with UV5 is the UV architecture type so the ACPI OEM_ID field can be used for other purposes going forward. The UV Arch Type selects the entirety of the MMRs available, with their addresses and fields defined in uv_mmrs.h.

2016-05-04x86/platform/UV: Add obtaining GAM Range Table from UV BIOSMike Travis1-2/+57
UV4 uses a GAM (globally addressed memory) architecture that supports variable sized memory per node. This replaces the old "M" value (number of address bits per node) with a range table for conversions between addresses and physical node (pnode) id's. This table is obtained from UV BIOS via the EFI UVsystab table. Support for older EFI UVsystab tables is maintained.

2009-12-16x86: uv: update XPC to handle updated BIOS interfaceRobin Holt1-10/+1
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.

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.
