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)

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
