x86/platform/uv: Update for UV5 NMI MMR changes

2020-10-07T07:09:50Z

The UV NMI MMR addresses and fields moved between UV4 and UV5 necessitating a rewrite of the UV NMI handler. Adjust references to accommodate those changes.

x86/platform/uv: Add and decode Arch Type in UVsystab

2020-10-07T07:06:10Z

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.

x86/platform/uv: Add UV5 direct references

Add new references to UV5 (and UVY class) system MMR addresses and fields primarily caused by the expansion from 46 to 52 bits of physical memory address.

x86/platform/uv: Update UV MMRs for UV5

2020-10-07T07:00:57Z

Update UV MMRs in uv_mmrs.h for UV5 based on Verilog output from the UV Hub hardware design files. This is the next UV architecture with a new class (UVY) being defined for 52 bit physical address masks. Uses a bitmask for UV arch identification so a single test can cover multiple versions. Includes other adjustments to match the uv_mmrs.h file to keep from encountering compile errors. New UV5 functionality is added in the patches that follow.

UV class systems no longer use System Controller for monitoring of CPU activity provided by this driver. Other methods have been developed for BIOS and the management controller (BMC).

x86/platform/uv: Remove UV BAU TLB Shootdown Handler

2020-10-07T06:45:39Z

The Broadcast Assist Unit (BAU) TLB shootdown handler is being rewritten to become the UV BAU APIC driver. It is designed to speed up sending IPIs to selective CPUs within the system. Remove the current TLB shutdown handler (tlb_uv.c) file and a couple of kernel hooks in the interim.
