From: Eric Anholt Date: Wed, 18 Feb 2009 19:34:47 +0000 (-0800) Subject: intel: tell libdrm whether we want a cpu-ready or gpu-ready BO for regions. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=40dd024be618d805b3744e15d25e115018641324;p=mesa.git intel: tell libdrm whether we want a cpu-ready or gpu-ready BO for regions. This lets us avoid allocing new buffers for renderbuffers, finalized miptrees, and PBO-uploaded textures when there's an unreferenced but still active one cached, while also avoiding CPU waits for batchbuffers and CPU-uploaded textures. The size of BOs allocated for a desktop running current GL cairogears on i915 is cut in half with this. Note that this means we require libdrm 2.4.5. --- diff --git a/src/mesa/drivers/dri/intel/intel_fbo.c b/src/mesa/drivers/dri/intel/intel_fbo.c index 54d6044ad3b..c9fb90f3b26 100644 --- a/src/mesa/drivers/dri/intel/intel_fbo.c +++ b/src/mesa/drivers/dri/intel/intel_fbo.c @@ -210,7 +210,8 @@ intel_alloc_renderbuffer_storage(GLcontext * ctx, struct gl_renderbuffer *rb, DBG("Allocating %d x %d Intel RBO (pitch %d)\n", width, height, pitch); - irb->region = intel_region_alloc(intel, cpp, width, height, pitch); + irb->region = intel_region_alloc(intel, cpp, width, height, pitch, + GL_TRUE); if (!irb->region) return GL_FALSE; /* out of memory?
