OK. Two last questions to be sure that I am doing correct things.

1/ I have to use an external tool to check leaks. Nothing to track per-process allocation from the kernel or from drm_intel?

2/ From libva and Mesa, I guessed that the correct way to use drm_intel for everything which is temporary (like a batch-buffer) is just to do:

- drm_intel_alloc - drm_intel_exec (for example) - drm_intel_unreference

Basically, I do _not_ have to be concerned about allocation overhead and how to reuse buffers: this is the role of libdrm_intel. Is it correct?

Thanks for your help.

Cheers, Ben

Hello all,

I am using drm_intel to access the HW. I would like to know if there is any way to know if my application frees all the bos I used. I would like to be sure I cleanly freed my resources and no bo is still referenced. Is there any tool in the memory allocation part of drm_intel to do that?

valgrind.

The kernel releases all client references upon termination. -Chris
