Some time ago I started fiddling around with SDL. I didn't even want to<br>
think about using the pvr2d stuff, so I decided to implement hardware<br>
acceleration using EGL/GLES2.<br>
<br>
I took some version of the harmattan SDL port, removed the pvr2d stuff,<br>
and added the EGL/GLES2 stuff to the X11 video code. It's not very<br>
cleanly added, and I'm sure there are various issues with window<br>
re-creation and whatnot.<br>
<br>
Features:<br>
- EGL/GLES2 based, no pvr2d stuff<br>
- Always uses a shadow buffer, because preserved flips aren't supported on<br>
the platform.<br>
- Automagically scales the application content to fullscreen using the GPU.<br>
- Software access to hardware surfaces implemented with glFinish() and<br>
EGL_KHR_lock_surface. I initially tried to use EGL_KHR_fence_sync instead<br>
of glFinish() but there seemed to be some flushing bug left in the driver<br>
causing problems. glFinish() should be OK on pvr, but on some other<br>
hardware it could be a problem. So it's not the most portable solution.<br>
- Supports color keyed and alpha blended blits. Only color keying has<br>
actually been tested.<br>
- some SDL tests, uqm and scummvm seem to work reasonably well<br>
<br>
The code is here [1] in case anyone is interested. It was languishing on<br>
my hard drive already for some time, and since I wasn't able to motivate<br>
myself to work on it further, I decided to set if free as is. The git<br>
history is a bit of a mess, but ATM I'm too lazy to clean it up.<br>
