efi/x86: move UV_SYSTAB handling into arch/x86

2019-08-08T08:01:48Z

The SGI UV UEFI machines are tightly coupled to the x86 architecture so there is no need to keep any awareness of its existence in the generic EFI layer, especially since we already have the infrastructure to handle arch-specific configuration tables, and were even already using it to some extent.

x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls

2019-02-15T14:19:56Z

Calls into UV firmware must be protected against concurrency, expose the efi_runtime_lock to the UV platform, and use it to serialise UV BIOS calls.

x86/platform/uv: Provide is_early_uv_system()

2018-10-02T19:29:16Z

Introduce is_early_uv_system() which uses efi.uv_systab to decide early in the boot process whether the kernel runs on a UV system. This is needed to skip other early setup/init code that might break the UV platform if done too early such as before necessary ACPI tables parsing takes place.

x86/platform/UV: Fix critical UV MMR address error

2018-03-28T18:19:45Z

A critical error was found testing the fixed UV4 HUB in that an MMR address was found to be incorrect. This causes the virtual address space for accessing the MMIOH1 region to be allocated with the incorrect size.
