Subject: [PATCH edk2-platforms v2 0/7] SynQuacer ACPI support
Date: Wed, 28 Feb 2018 19:24:14 +0000	[thread overview]
Message-ID: <20180228192421.17684-1-ard.biesheuvel@linaro.org> (raw)

This implements ACPI support for the SynQuacer platforms.

Changes since v1:
- improve commit log (#1, #2)
- replace bare numbers with symbolic constants (#2)
- add Leif's R-b (#4)
- add patches #6 and #7

Note that supporting ACPI on this SoC is non-trivial, due to the quirky
DesignWare RCs and the pre-ITS that sits between the PCIe RCs and the GICv3.
However, the most important issue has been addressed by modifying the static
SMMU mapping that sits between the CPUs and the PCIe config space, working
around the ghosting issue that occurs on these RCs, due the complete lack of
type 0 config TLP filtering by the [non-existent] root port. (This was tested
using the 20180226-LB1.1-ACPI-ramfw.bin SCP firmware image, which is not [yet]
installed by default on DeveloperBox hardware)

That leaves the MSI issue, which is worked around by limiting MSI support to a
single RC. In the presented configuration, this is RC #1, which connects to the
x16 slot [and nothing else] on the DeveloperBox PCB. The onboard PCIe devices
(XHCI + SATA) work without problem using wired interrupts only, and so RC #0
has MSI support disabled. This means cards that require MSI support should
be inserted into the x16 slot, which is likely to be the preferred slot in
such cases anwyay (e.g., when using NVME or high end networking plugin cards)

Patch #1 fixes a minor issue in the slot-to-BDF mapping.

Patch #2 modifies the static PCIe window configuration so it can be described
using ACPI as well as DT.

Patch #3 introduces the static ACPI tables that describe the fixed platform
devices and peripherals to the OS.

Patch #4 adds a menu option to the platform driver to make ACPI vs DT user
selectable.

Patch #5 adds support for describing the eMMC controller using a SSDT table
which is only installed if eMMC support is enabled.

Patch #6 adds a _STA method implementation to the PCIe RC devices so that
they are only exposed to the OS when running on a platform that has one of
the several ECAM workarounds enabled. Otherwise, we can still boot via ACPI
using platform devices, but the PCIe RCs are unavailable.

Patch #7 extends the _STA method for PCI0 to take the presence detect GPIO
into account. This is necessary because on the SynQuacer evaluation board,
any attempt to access the device registers will lock up the system if no
card is inserted into the slot.

Note that driver support for the eMMC and network controller only landed in
v4.15, but when using a SATA driver and a plugin network card that does have
driver support, these patches should allow the SynQuacer based platforms to
boot stock Debian Stretch/Fedora/Centos etc installers.
