The branch stable/13 has been updated by vexeduxr: URL: https://cgit.FreeBSD.org/src/commit/?id=8591ee986b22007a98ded2f3dc86e8065f14b213 commit 8591ee986b22007a98ded2f3dc86e8065f14b213 Author: Ahmad Khalifa <vexeduxr@FreeBSD.org> AuthorDate: 2026-01-04 13:15:37 +0000 Commit: Ahmad Khalifa <vexeduxr@FreeBSD.org> CommitDate: 2026-01-12 17:28:03 +0000 loader.efi: only use firmware provided Blt on GOP gfx_state.tg_private points to a EFI_GRAPHICS_OUTPUT_PROTOCOL only when using GOP. The firmware provided Blt functions on UGA platforms have been observed to not work on old MacBooks, and are likley hit or miss anyways as UGA has been deprecated since 2006.
