EGL broken under Weston (Wayland) on Utilite Pro with 3.10.17

Hello!

I've sought help about this on the Utilite forums but almost no one has tried Wayland yet. Weston starts fine using the fbdev backend and weston-simple-egl even works but that's about it. I've tried to start XBMC and Neverball (SDL2, built for GLES) and both complain about being unable to create an EGL surface. I built eglinfo (./waf configure --platform=wayland --device=imx6) and I get this.

No valid surface: EGL failed to allocate resources for the requested operation.

eglMakeCurrent() failed: Arguments are inconsistent (for example, a valid context requires buffers not supplied by a valid surface).

I've noted several things about this. This error appears when it attempts to display information about OpenVG. If I use libOpenVG_3D.so instead of libOpenVG_355.so, I don't get an error but it reports that OpenVG is unaccelerated and the above programs still do not work. If I run the framebuffer version of eglinfo, no error appears and it reports that OpenVG is accelerated as it should be. This could be a red herring but I have noticed from using strace that libOpenVG.so is loaded shortly before the above programs fail. I've looked into the error itself and it maps to a return value of EGL_BAD_ALLOC.

I primarily use a self-built hard float Gentoo system and I have created a flexible gpu-viv-bin-mx6q package that I plan to release when I get this working. I do feel that I know what I'm doing (built Cairo with GLES support, patched Weston as necessary, selected the right Vivante libraries) but obviously there is a lot of scope for error when using Gentoo. I also tried jas-mx's Debian Jessie image that he used in a blog post to demonstrate Weston acceleration. I got exactly the same result but then again, he used the UDOO and he never mentioned trying anything more demanding that weston-simple-egl. Finally, I built fsl-arm-yocto-bsp (dora_3.10.17-1.0.1) using the imx6qsabresd/wayland target, thinking that couldn't possibly fail, but I got the same result yet again!

I did most of this testing using CompuLab's kernel patches rebased onto imx_3.10.17_1.0.1_ga. I have mostly used my own configuration but I did also try CompuLab's default configuration against Gentoo. The latter does not disable anything that isn't already disabled in the Freescale default configuration so I don't believe I am missing anything here. The fact that the framebuffer version of eglinfo seems to work also makes me think this must be a userspace issue.

In terms of Weston versions, I have tried 1.4.0, 1.5.0, 1.5.92 and fsl-arm-yocto-bsp currently uses 1.3.1. Seems we can rule this out.

Even if you don't know what the problem might be, please do comment if you have had success with anything more than just weston-simple-egl, especially if it was on a Utilite. If you wish to try this stuff on a Utilite yourself, I have found that it can't cope with 1080p, seemingly due to some IPU issue. I have to switch it to 720p first but I'll look into that more once I get the above issue resolved.

Nobody? I've had to start looking at the open Etnaviv drivers instead and I think I'm actually closer to success with those. That's not what you want now, is it? :smileywink:

Any luck with EGL on iMX6? Im getting EGL_BAD_ALLOC when calling eglGetDisplay , but on a Riotboard (iMX6 Solo).

A couple more things to add.

Freescale builds Weston with  -DEGL_API_WL. At first I thought this was a typo and should have been -DWL_EGL_PLATFORM but now I see that the former also exists. But only in HAL/gc_hal_eglplatform.h. This is only referenced by wayland-viv/gc_wayland_protocol.h. They do look important but neither of these are referenced anywhere else in gpu-viv-bin-mx6q or in Weston either. Surely that makes the  -DEGL_API_WL flag useless? I wonder if they are used when building libEGL-wl.so.

I've also noticed the i.MX DRM driver in the kernel staging area. Having used the open Radeon drivers on my desktop, I think this is likely to be the future. I did give it a try, hoping that it would work with the Weston DRM backend and maybe even solve the issue above but it doesn't detect a HDMI connection. Can anyone tell me more about this driver?
