Hi Wookey,
This was something bouncing around in the Graphics Working Group back in the day. Alexandros as I recall was the key dev. As far as a shim goes given the effort that would have been involved and the lack of interest, it wasn't worked on.
For ARM64 and QT would a move to GLES be a "good thing?" Yes.
When it comes to graphics drivers today for arm hardware GLES is pretty universal. GLES is a standard, there is compliance through
*Shouts* ThunderX2 Workstation very loudly at this point, following by Linaro Developer Box, Macchiato bin.....
Linaro is more than Android!
Quite. This is exactly the tension behind the dicussion - while arm64 machines are mainly mobile so far, we're finally starting to see bigger and more capable systems that you'd actually be happy to use as a desktop/laptop.
Hence Wookey's question - is it possible to have a single sensible answer for both the (large) mobile hardware user base and the (smaller, but growing) bigger system users? We've seen conflicting information in that thread, hence asking here! :-)
That is Vulkan. There is no mobile&embedded vs desktop fracture like there is with GLES vs GL. In the design of the Vulkan standard that was one mistake they were trying to address.
I personally would aim for Vulkan.
Is it true that most PCIe graphics cards (and drivers) will also support GLES as well as GL? I've seen that asserted.
As a litmus test, I don't see any GLES drivers on nVideas website. Both Vulkan and GL are there tho.
