[GIT PULL 00/40] EFI changes for v4.7

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Folks, here's the queue of EFI material for v4.7. This is probably the
biggest EFI pull ever sent, and there quite a few different topics
covered.

On the plus side the majority of new features (EFI Memory Attribute
tables, EFI capsules, GOP framebuffer) are basically architecture
independent, and some of the existing architecture-specific code has
been generalised and moved to drivers/firmware/efi.

The following changes since commit c3b46c73264b03000d1e18b22f5caf63332547c9:

  Linux 4.6-rc4 (2016-04-17 19:13:32 -0700)

  efi/runtime-wrappers: Remove ARCH_EFI_IRQ_FLAGS_MASK ifdef (2016-04-25 16:53:59 +0100)

----------------------------------------------------------------
 * Drop the unused EFI_SYSTEM_TABLES efi.flags bit and ensure the
   ARM/arm64 EFI System Table mapping is read-only - Ard Biesheuvel

 * Add a comment to explain that one of the code paths in the x86/pat
   code is only executed for EFI boot - Matt Fleming

 * Improve Secure Boot status checks on arm64 and handle unexpected
   errors - Linn Crosetto

 * Remove the global EFI memory map variable 'memmap' as the same
   information is already available in efi::memmap - Matt Fleming

 * EFI Memory Attribute table support for ARM/arm64 - Ard Biesheuvel

 * EFI GOP framebuffer support for ARM/arm64 - Ard Biesheuvel

 * EFI Bootloader Control driver for storing reboot(2) data in EFI
   variables for consumption by bootloaders  - Jeremy Compostella

 * Core EFI capsule support - Matt Fleming

 * EFI capsule char driver - Kweh, Hock Leong

 * EFI memory map code unification for ARM and arm64 - Ard Biesheuvel

 * Add generic EFI support for detecting when firmware corrupts cpu
   status register bits (like IRQ flags) when performing EFI runtime
   service calls - Mark Rutland
