[PATCH 0/4] arm64: dts: qcom: x1e80100: Add IRIS video codec

[Stephan Gerhold]

Add the necessary definitions to enable the IRIS video codec for
accelerated video decoding on the X1E CRD and Lenovo ThinkPad T14s. The
additions are largely copied as-is from sm8550.dtsi with some minor changes
necessary for X1E.

The PAS interface used to boot the IRIS firmware is not functional in EL2.
The code to start it without using PAS exists already in the Venus driver,
but was not ported over to IRIS yet. Discussions how to model the
video-firmware IOMMU are still ongoing, so disable IRIS in x1-el2.dtso for
now to avoid regressions when running in EL2.

[PATCH 1/4] arm64: dts: qcom: x1e80100: Add IRIS video codec

[Stephan Gerhold]

Add the IRIS video codec to accelerate video decoding/encoding. Copied
mostly from sm8550.dtsi, only the opp-table is slightly different for X1E.
For opp-240000000, we need to vote for a higher OPP on one of the power
domains, because the voltage requirements for the PLL and the derived
clocks differ (sm8550.dtsi has the same).

[PATCH 2/4] arm64: dts: qcom: x1-el2: Disable IRIS for now

[Stephan Gerhold]

The reset and IOMMU management for remoteprocs like IRIS is implemented in
the hypervisor for older targets such as X1E [1]. When running in EL2, this
functionality is missing and the PAS interface normally used by IRIS to
boot the video firmware is not working.

The Venus driver supports starting the video firmware without using the PAS
interface. The same code also works for X1E when running in EL2. However,
for the new IRIS dt-bindings it was decided to avoid using the dummy
"video-firmware" node in the device tree to describe the IOMMU [2].
Discussion is still ongoing how to describe this properly [3].

To avoid regressions when running in EL2, add a TODO in x1-el2.dtso for now
and disable IRIS even when it was enabled by the board.

[PATCH 3/4] arm64: dts: qcom: x1e80100-crd: Enable IRIS video codec

[Stephan Gerhold]

IRIS firmware for x1e80100-crd is already upstream in linux-firmware in the
default path, so enable IRIS for the CRD to accelerate video decoding.

It looks like the X1P CRD might need a different IRIS firmware (possibly
even changes in the Linux kernel driver), so keep it local to the X1E CRD
for now.

Just to confirm my understanding of above statement. The patches below
works w/ the Gunyah and Linux running at NS-EL1 and "not functional in
EL2" means Video working w/ the KVM Hypervisor on X1E right?

Yes, the patches enable video acceleration when running Linux with
Gunyah as usual. I added an extra patch to disable IRIS when running
with KVM, because my patches would introduce regressions otherwise.

The old Venus driver does support starting the video firmware when
running without Gunyah (for KVM on the Chrome platforms). The same code
works for KVM on X1E, so we could easily enable it once there is a
solution for the describing the video-firmware IOMMU in the device tree.
Mukesh is working on solving that for SA8775p [1].

Oh, yeah you're right. I haven't looked at that patch series for a while
because it went through so many revisions. Wouldn't have expected to
find that patch in there, especially without an indication in the cover
title...

But we can keep this short: The opp-table in that patch is wrong, they
don't have the correct required-opps for opp-240000000 like I described
in the commit message above. They could have easily known that if they
had asked the video team internally for review, because we had a pretty
long discussion with them if this is also needed for X1E. :-(

I'll comment there.

Thanks,
Stephan

I didn't include that because the firmware-name setup isn't as
straightforward for that as for the T14s. I think all the Thena variants
have existing "firmware-name"s for ADSP though, so I can try to make a
patch that adopts the existing prefix for all the laptops that make use
of x1-dell-thena.dtsi. Or even better would be if you can send me a
tested patch to include. :-)

Thanks,
Stephan
