Subject: [PATCH 0/3] video/efi: Support FIRMWARE_EDID on non-x86
Date: Wed, 19 Nov 2025 13:30:12 +0100	[thread overview]
Message-ID: <20251119123011.1187249-5-ardb+git@google.com> (raw)

From: Ard Biesheuvel <ardb@kernel.org>

Refactor the screen_info handling so non-x86 platforms booting via the
EFI stub also have access to the EDID data exposed by the EFI boot
services.

Ard Biesheuvel (3):
  efi: Wrap screen_info in efi_screen_info so edid_info can be added
    later
  video/edid: Use getter function for edid_info
  efi: Add FIRMWARE_EDID support
