The SDL forums have moved to discourse.libsdl.org.
This is just a read-only archive of the previous forums, to keep old links working.

Hi! I've just done video driver for rendering directly to framebuffer, it should work on any custom board with i.MX6 processor. Supported windows management, both OpenGL ES 1.0 and OpenGL ES 2.0.
You can view the code from https://github.com/mastermind-/SDL-mx6/tree/release-2.0.3-mx6.
What do you think about the code? Have any remarks?
I'd be glad if someone will find it useful. May be it can be pushed to upstream?

Sweet, thanks! :)

Do you have a patch or set of patches against SDL in Mercurial?

There's another related patch here: https://bugzilla.libsdl.org/show_bug.cgi?id=2386

I think we need to figure out a way to consolidate these under a "SOC" backend, or risk having a ton of 99% similar backends, and that will become a support nightmare.

You can get patches from github:
https://github.com/mastermind-/SDL-mx6/commit/e7f55c855d6336d9892d5f811d0a06e5d35b9780.patch - master
https://github.com/mastermind-/SDL-mx6/commit/ebc2901f67ee82ef555845c17f39b9663ab98225.patch - 2.0.3

Didn't know about this patch.
Nice work, but mine is little better
1) Loads EGL library dinamically. In theory it can be compiled with X/directfb/wayland drivers too, they will share EGL native types definitions, which are binary compatible. Ideally, SDL_egl.c should be compiled separately for every driver.
2) Doesn't have code garbage from rpi driver
3) Build using cmake

Btw, it doesn't 100% fit to common "SOC" backend because to load EGL library using SDL_GL_LoadLibrary it should get native display using function from this library That's why I had to reimplement SDL_GL_LoadLibrary.

Okay, this patch is in SDL, thanks!

I added an additional change so the correct desktop video mode is reported.

Cheers!

Hi! I've already fixed this issue few days before - https://github.com/mastermind-/SDL-mx6/commit/99ecdd7ecc2ffac300ef8e9b200e2c829cb619e1.patch
I've found error in your patch: in MX6_GLES_LoadLibrary you are calling eglGetDisplay with native_display which is not initialized yet (it will be filled in MX6_UpdateDisplay later) and egl_display will be invalid. Although It may work on some cases when eglGetDisplay(0) returns valid egl_display, but fbGetDisplayByIndex can return non-zero value (in my case).
Please apply my patch, it's tested and now in production :)

Can you provide a patch relative to the current code in Mercurial?

Thanks!
