To use the function intelSwapBuffers, I change the function called by
dri2SwapBuffers with (*pdraw->psc->core->swapBuffers)(pdraw->driDrawable);.
Now, I can use the function intelSwapBuffers but in the function
intelCopyBuffer (intel_blit.c), I have a segmentation fault when it does dst =
intel_get_rb_region(&intel_fb->Base, BUFFER_FRONT_LEFT);
intel_get_rb_region(&intel_fb->Base, BUFFER_FRONT_LEFT) returns an irb->region
= NULL.
My question is : Why the irb->region is NULL and How to do to have a correct
irb->region ?
Thanks, Nicolas

Objet : [Mesa3d-users] How to use the intelSwapBuffers function ?
Hi all,
I'm working with the intel chipset.
I want to use the function glXSwapBuffers with a vertical synchronisation.
But when I call glXSwapBuffers, glXSwapBuffers call the function
dri2SwapBuffers which is in the file
...\mesa-7.4.0-1\src\mesa\src\glx\x11\dri2_glx.c. But, I want to use the
function intelSwapBuffers
(...\mesa-7.4.0-1\src\mesa\src\mesa\drivers\dri\intel\intel_swapbuffers.c).
So I think that glXSwapBuffers must call the function driSwapBuffers
(...\mesa-7.4.0-1\src\mesa\src\glx\x11\dri_glx.c). And I think that
driSwapBuffers of the dri_glx.c file call the function driSwapBuffers which is
in the file ...\mesa-7.4.0-1\src\mesa\src\mesa\drivers\dri\common\dri_util.c.
And to finish this function driSwapBuffers of dri_util.c call the function
intelSwapBuffers.
is it right ?
If yes, how to do to use the function driSwapBuffers instead dri2SwapBuffers in
glXSwapBuffers ?
Else , somebody can explain me how to use the function glXSwapBuffers with a
vertical synchronisation ?
Thanks, nicolas
