2023-08-22efi/runtime-wrappers: Remove duplicated macro for service returning voidArd Biesheuvel1-1/+3
__efi_call_virt() exists as an alternative for efi_call_virt() for the sole reason that ResetSystem() returns void, and so we cannot use a call to it in the RHS of an assignment. Given that there is only a single user, let's drop the macro, and expand it into the caller. That way, the remaining macro can be tightened somewhat in terms of type safety too. Note that the use of typeof() on the runtime service invocation does not result in an actual call being made, but it does require a few pointer types to be fixed up and converted into the proper function pointer prototypes.

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.

2019-02-15x86/platform/UV: Remove unnecessary #ifdef CONFIG_EFIHedi Berriche1-4/+0
CONFIG_EFI is implied by CONFIG_X86_UV and x86/platform/uv/bios_uv.c requires the latter, get rid of the redundant #ifdef CONFIG_EFI directives. Cleanup, no functional changes.

2018-10-02x86/platform/uv: Provide is_early_uv_system()Mike Travis1-0/+6
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.

2018-03-28x86/platform/UV: Fix critical UV MMR address error[email protected]1-1/+1
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.
