GBM application failed with error EGL_BAD_DISPLAY #49

Closed namtrino closed 1 year ago

namtrino commented 1 year ago

I test ozone-gbm on rk3566 but it failed with error below.

[ERROR:gl_surface_egl.cc(1382)] eglInitialize Default failed with error EGL_BAD_DISPLAY
[ERROR:gl_ozone_egl.cc(20)] GLSurfaceEGL::InitializeOneOff failed.
[ERROR:viz_main_impl.cc(161)] Exiting GPU process due to errors during initialization

But kmscube and glmark2-es2-drm work ok.

Is this a gbm driver issue?

??? the yocto sdk with chromium worked well for years...

JeffyCN commented 1 year ago

i was using this to build images: https://github.com/JeffyCN/yocto-manifests

The Chromium Wayland from https://github.com/JeffyCN/yocto-manifests can run. But I was faced with two issues, poor video playback performance and it crashed randomly.

JeffyCN commented 1 year ago

video playback is at the best performance, it has hw dec and dma importing and gpu rendering. (using v4l2vda+v4l2-mpp plugin+mpp)

crash issue should related to chromium-wayland or chromium framework, you can report to chromium issue system or try different versions

chromium-x11 should work too.

gbm should be used in chromiumos, it requires more patches.

fydeos has chromiumos-like sdk for rk3399 and rk3588 using gbm, i don't have their patches.

JeffyCN commented 1 year ago

one guess would be using egl get platform display api to get egl gbm display, instead of the legacy egl get display api

Hi, chromium gbm require EGL version 1.5 (current version is 1.4) . Is it possible to upload version 1.5 to public?

JeffyCN commented 1 year ago

it's almost impossible to upgrade it.

and i don't think it requires that, because the google do have chromebook with chromeos(chrome + gbm) for 3288 and 3399, and fydeos has chromiumos(chromium + gbm) for 3399/3588.

namtrino commented 1 year ago

I already tested with RK3399 with yocto-manifest. It also failed EGL_BAD_DISPLAY.

JeffyCN commented 1 year ago

it's been tested by lots of people for years...

JeffyCN commented 1 year ago

FYI, i've heard they use mali with dummy platform + google's minigbm for chrome os/chromium os's ozone gbm

namtrino commented 1 year ago

Thank you for an information. I think I should study FydeOS with rockchip platform first. Because look like they use mpp (https://github.com/openFyde/overlay-rock5b-openfyde/blob/main/sys-kernel/chromeos-kernel-5_10/files/012-add-virtual-v4l2-devices.patch).

BTW, I will closed this issue because meta-rockchip focus on wayland with linux gbm.
