More EFI ARM64 Work, Additional UEFI 2.5 Features In Linux 4.4

Written by Michael Larabel in Hardware on 3 November 2015 at 08:15 AM EST. Add A Comment

One of the many pull requests sent in today by Ingo Molnar for the Linux 4.4 merge window was the EFI subsystem update.

The EFI changes in Linux 4.4 include more code generalization work to make the traditionally x86 code more happy for 64-bit ARM (U)EFI support, support for various EFI extensions, new debugging parameters, code clean-ups, and more.

The EFIFB frame-buffer driver in Linux 4.4 now supports 64-bit frame-buffer addresses as one of the additions. Support for UEFI 2.5's EFI_PROPERTIES_TABLE, which is initially used to indicate whether memory protection is enabled but could be used for other configuration data too, is now supported. As part of this is support for the EFI_MEMORY_RO attribute of UEFI 2.5.

More details on the EFI changes for Linux 4.4 via the pull request.
