[PATCH 0/8] arm64: defconfig: enable several options useful for ARM64 server platforms

[Timur Tabi]

ACPI-based ARM64 server platforms based, like the Qualcomm Datacenter
Technologies QDF2400, need several features and drivers enabled for
full functionality.  This patchset enables many of those features.

The first patch, "resynchronize the defconfig" refreshes the ARM64
defconfig so that it's aligned with savedefconfig.  This needs to be
done periodically, so that new patches avoid merge conflicts.  

If the first patch does not apply cleanly, I ask the maintainer to 
refresh it himself manually, following the instructions in the commit
message.  The remaining 7 patches should apply cleanly on top of that.

Timur Tabi (8):
  arm64: defconfig: resynchronize the defconfig
  arm64: defconfig: enable ACPI_CPPC_CPUFREQ
  arm64: defconfig: enable TCG_TPM and TCG_CRB
  arm64: defconfig: enable BLK_DEV_NVME
  arm64: defconfig: enable EFI_VARS and EFI_CAPSULE_LOADER
  arm64: defconfig: enable support for PCIe hotplug
  arm64: defconfig: enable APEI and GHES features
  arm64: defconfig: enable EDAC options

[PATCH 1/8] arm64: defconfig: resynchronize the defconfig

[Timur Tabi]

Defconfig files become unsynchronized over time as Kconfig entries are
added, removed, or changed.  Making specific changes to the defconfig
becomes difficult as unrelated differences can interfere.  This problem
is easily remedied:

	make defconfig
	make savedefconfig
	cp defconfig arch/arm64/configs/defconfig
	git add arch/arm64/configs/defconfig
	git commit -s

[PATCH 5/8] arm64: defconfig: enable EFI_VARS and EFI_CAPSULE_LOADER

[Timur Tabi]

Many ARM64 server systems boot via EFI, so enable support for some EFI
options to allow applications to interact with EFI.

CONFIG_EFI_VARS enables sysfs support for reading and writing variables

CONFIG_EFI_CAPSULE_LOADER allows the user to update the EFI firmware.

[PATCH 7/8] arm64: defconfig: enable APEI and GHES features

[Timur Tabi]

ARM64 server platforms can support ACPI Platform Error Interface (APEI)
and Generic Hardware Error Source (GHES) features, so enable them.

Platforms which support the firmware-first RAS error reporting model
require APEI and GHES functionality for the OS to receive and report
error records provided by the platform.

PCIe AER functionality is required for PCIe AER errors to be properly
reported and recovered from.

[Timur Tabi]

EDAC (Error Detection and Correction) and EDAC_MM_EDAC are required to

memory errors from the APEI GHES framework as well as reporting these
types of errors to the user space via the memory controller trace event.

I see there are patches queued in linux-next enabling some arm64 TPM CRB
support, which I believe are related.

As I have commented elsewhere [1], I think those have been taken
prematurely, and I'm not sure it's a good idea to enable this just yet,
due to that. There are spec issues to be addressed in the draft that is
still open.

Isn't efivarfs preferred for that these days, or have I imagined that?

Ok, I will drop this patch in v2.

So my research suggests that efivarfs is a replacement for CONFIG_EFI_VARS.
We may still have some older programs that use the sysfs entries, but I'm
not sure.

Regardless, I will drop EFI_VARS from v2 of the patset, and just set
EFI_CAPSULE_LOADER.
