[Mesa3d-users] Re : How to use the intelSwapBuffers function ?

[Nicolas C. <nic...@ym...>]

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

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
