Subject: [edk2-devel] [PATCH 09/37] OvmfPkg: remove Csm/BiosThunk/VideoDxe
Date: Sat, 11 Nov 2023 00:57:52 +0100 [thread overview]
Message-ID: <20231110235820.644381-10-lersek@redhat.com> (raw)
In-Reply-To: <20231110235820.644381-1-lersek@redhat.com>
Csm/BiosThunk/VideoDxe is not used by any platform at this point, remove
it.
This patch removes mentions of the following CSM resources from the source
code:
- GUIDs (protocols or otherwise):
- gEfiLegacyBiosGuid
- gEfiLegacyBiosProtocolGuid
- gEfiVgaMiniPortProtocolGuid
- headers:
- FrameworkDxe.h
- Guid/LegacyBios.h
- Protocol/LegacyBios.h
- Protocol/VgaMiniPort.h
- PCDs:
- PcdBiosVideoCheckVbeEnable
- PcdBiosVideoCheckVgaEnable
- PcdBiosVideoSetTextVgaModeEnable
which extends the list of resources scheduled for removal to:
- GUIDs (protocols or otherwise):
- gEfiLegacyBiosGuid
- gEfiLegacyBiosProtocolGuid
- gEfiVgaMiniPortProtocolGuid
- headers:
- FrameworkDxe.h
- Guid/LegacyBios.h
- Protocol/LegacyBios.h
- Protocol/VgaMiniPort.h
- PCDs:
- PcdBiosVideoCheckVbeEnable
- PcdBiosVideoCheckVgaEnable
- PcdBiosVideoSetTextVgaModeEnable
