[Mesa-dev] [PATCH 0/6] New DirectFB sw for Gallium's EGL state tracker

[Ilyes Gouta]

These are few patches that add a new DirectFB native and winsys backend
for the EGL state tracker. This is just about the underlaying infrastructure
that enables DirectFB surface to act as EGL render targets for gallium's
softpipe and llvmpipe sw renderers.

A DirectFB application can now do:

desc.flags = DSDESC_CAPS|DSDESC_WIDTH|DSDESC_HEIGHT|DSDESC_PIXELFORMAT;
desc.caps = DSCAPS_DOUBLE; /* |DSCAPS_PRIMARY */
desc.width = 640;
desc.height = 480;
desc.pixelformat = DSPF_ARGB;
pDfb->CreateSurface(pDfb, &desc, &pSurface);

context = eglCreateContext(display, config[0], EGL_NO_CONTEXT, NULL);
surface = eglCreateWindowSurface(display, config[0], pSurface, NULL);

eglMakeCurrent(display, surface, surface, context);

in order to embed a mesa/EGL rendering into a target surface which could
subsequently serve as a source for further processing.
