Subject: [PATCH v2 2/3] arm64: dts: qcom: sc7280: Move video-firmware to chrome-common

If the video-firmware node is present, the venus driver assumes we're on
a system that doesn't use TZ for starting venus, like on ChromeOS
devices.

Move the video-firmware node to chrome-common.dtsi so we can use venus
on a non-ChromeOS devices.

At the same time also disable the venus node by default in the dtsi,
like it's done on other SoCs.

Changes look good. Is this tested on SC7280 ?

Hi Vikash,

I didn't test it myself on sc7280 (just qcm6490-fp5) but dtx_diff
reports no differences except for status = okay property being added, so
there should be no change on those boards. See below.

0x2184 is a secure SID. I think qcm6490-fairphone-fp5.dts needs to override the
iommus property as well to retain only the non secure SID i.e 0x2180 ? I am
seeing below crash

Could you please reconfirm if Video SID 0x2184 (and mask) is allowed by the

I tested on SC7280 (herobrine) and all good.

Hi,

On FP5 it seems it's no problem to have both SIDs in there, probe and

Are you using different firmware than QCM6490.LA.3.0 on the device where
you tested this?

There is something wrong here.

RB3 board uses venus-5.2
RB5 board uses vpu-1.0
Only sc7280 uses vpu-2.0

In any case, I don't know much about the venus & iommu setup here. I can
try removing the 0x2184 SID and test if venus still works on FP5.
Also should the chromebooks keep that iommu entry or not?

Please remove 0x2184 SID and confirm specifically encoder works. This SID is for
encoder.

> Also should the chromebooks keep that iommu entry or not?
Chrome-common can have 0x2184 since its no-TZ based solution. So in sc7280.dtsi,
you can keep the default SID i.e 0x2180 (with respective mask) and in
chrome-common, we can override the iommus property with 0x2180 and 0x2184.

Hi Vikash,

I'm moving 0x2184 to chrome-common in v3 but I couldn't test venus
encoding myself since I just don't know *how* to test it.

Would be nice if you could share how you test venus (decoding &
encoding) since seemingly nobody (at least in the postmarketOS
community) seems to know how to test/use it properly. See also
