I remember when Rob first started working on adreno support for the HP Touchpad tablet. I think I still have it lying around somewhere. It is amazing to see how far linux support has come for embeded graphics since.

Thanks robclark for the fast answer. Yes, this work here is related to a newer SoC. But there were some really super-interesting kernel 5.x additions and improvements regarding older Snapdragon SoCs (down to the Adreno 200 line) which would be great to see in 4.14 or 4.19. Whatever, - I shouldn't complain and do it myself. But then I had first to go onto some kind of a "Linux University" and learning quite a lot in regard to kernel hacking..

However, it is really unfortunate that not even the kernel improvements are ported back to any of the older LTS kernel. One should take into account that regarding Android even 4.14 and 4.19 are quite "new". That would make really a lot of things much easier especially for non-professional code hackers like the XDA folks.
OTOH, I've noticed a trend that once a given SoC has pretty reasonable support upstream, we start to see a lot of android devices which use that particular SoC getting upstream kernel support as well (for example, the great work that the postmarketos folks do)
I suppose it doesn't help folks stuck on 4.x kernels, but the chromeos-5.4 kernel these devices are currently shipping with is 5.4 + backmerges from 5.4.y + backports of all the new hw enablement.. so I suppose it might be a reasonable place to look for patches once more android devices are using 5.4.

Since chromebooks have a much longer support window compared to android phones, we need something that we can continue to support long after qcom has forgotten about (by then) older generations ;-)
It's also why we (and qcom+linaro) have been doing so much work on upstreaming kernel support. Upstream kernel works out of the box, I've been testing my drm/msm pull requests on lazor since last year, before it was shipping.

From the article:
"The Adreno 600 series open-source graphics support is overall in fairly robust shape these days thanks to the work of Qualcomm, Google, and other parties."
Since it's Google working on this together with Qualcomm I would say it's a no brainer that they plan to use this in Chromebooks. Why else would they put resources into this?

Adreno 660 + 635 Now Supported By The Open-Source OpenGL/Vulkan Drivers
Phoronix: Adreno 660 + 635 Now Supported By The Open-Source OpenGL/Vulkan Drivers
For going along with the newly added support in the MSM DRM kernel driver, Mesa's Freedreno Gallium3D OpenGL and Turnip Vulkan drivers have landed support for the Adreno 660 and Adreno 635 graphics processors...
