Subject: [PATCH v3 0/4] EFI System Resource Table support
Date: Tue, 19 Apr 2022 11:32:23 -0400	[thread overview]
Message-ID: <Yl7WHv6+M+eJwQep@itl-email> (raw)

[-- Attachment #1: Type: text/plain, Size: 1590 bytes --]

This adds support for the EFI System Resource Table.  This involves
reserving the table in Xen and adding a new hypercall so that dom0 can
access it.

Changes since v2:

- Use the esrt_desc global variable instead of passing it as a function
  parameter
- Add an overflow check for the ESRT size
- Create a new memory region for the ESRT to avoid wasting memory
- Add hypercall to retrieve the ESRT
- Add file local variables used during development
- Remove extra consts
- Follow the EFI naming convention in struct definitions
- Move struct definitions to header file
- Fix inverted logic in overflow check
- Remove BUILD_BUG_ON()s
- Avoid overriding attribute of memory descriptor containing ESRT

Changes since v1:

- Remove the esrt_status enum
- Use EFI types
- Fix style nits
- Remove an unused overflow check

  Grab the EFI System Resource Table and check it
  Add a dedicated memory region for the ESRT
  Add a new hypercall to get the ESRT
  Add emacs file-local variables
