Subject: Re: openGL ES vs openGL on aarch64 for Qt
I'm okay with aligning aarch64 more with x86_64.. the timing is however funny
because Qt just announced that over the long run they will stop embracing
Thanks for the news.
openGL ES is fine for armv6 and armv7, but I am
thinking of switching aarch64
from openGL ES to openGL as aarch64 systems can now
use standard PCIe gfx
Some aarch64 SoC still have embedded GPU which
may support only ES version,
Are you asking because of some compilation incompatibility somewhere ? I
remember there were some apps (particularly in the KDE stack) blindly assuming
that OpenGL would always be available in Qt.. I was hoping we could fix those
Yes, it is one of the reason, indeed.
over time. Also note that OpenGL support is on its
(slow and very long) way out
of Qt: https://www.qt.io/blog/qt-5.14-has-released
The plan is to go with the more "native" lower level newer APIs like Vulkan,
Thanks for the link.
Or are you concerned about the lack of feature by feature compatibility with x86?
IMO, having less differences between architectures is generally better.
that is a valid concern then I think, and if it makes
any life easier we should
align. :-) But the alignment could be by changing x86 to the more modern 3D apis ..
although I don't know how painful that is going to be.
We need to support this new API anyway, not sure if we could support both for some time.
Fabian, you may have a clue?
