[PATCH 0/9] [v3] 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 8 patches should apply cleanly on top of that.

Timur Tabi (9):
  [v3] arm64: defconfig: resynchronize the defconfig
  arm64: defconfig: enable ACPI_CPPC_CPUFREQ
  arm64: defconfig: enable BLK_DEV_NVME
  [v2] arm64: defconfig: enable EFI_CAPSULE_LOADER
  arm64: defconfig: enable support for PCIe hotplug
  arm64: defconfig: enable APEI and GHES features
  [v2] arm64: defconfig: enable EDAC options
  arm64: defconfig: enable QCOM_L2_PMU and QCOM_L3_PMU
  arm64: defconfig: enable the Qualcomm Technologies EMAC Ethernet
    driver

[PATCH 1/9] [v3] 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 <sha>

[PATCH 3/9] arm64: defconfig: enable BLK_DEV_NVME

[Timur Tabi]

NVME is non-volatile storage media attached via PCIe. NVME devices
typically have much higher potential throughput than other block
devices, like SATA, NVME is a must-have requirement for ARM64 based
servers.

[PATCH 6/9] 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.

Catalin,

Any chance of getting these into 4.12?

The arm-soc folks usually deal with defconfig updates, so please resend this
to arm@kernel.org, although I suspect it's too late for 4.12 given that the
merge window is now open. The "resynchronize" patch is also likely to
conflict with any other pending changes to the file.

I'm sure it will conflict, but the defconfig has to be synchronized sooner
or later.  Frankly, I think Linus should just do a "batch resynchronize" of
every defconfig in every release (e.g. make it the last commit).
arch/arm64/configs/defconfig is way off today, and it's only going to get worse.

[PATCH 7/9] [v2] arm64: defconfig: enable EDAC options

[Timur Tabi]

Enable EDAC (Error Detection and Correction) support for ARM64 server
systems that feature it, so that user space applications can be
notified of memory errors.
