Relocation processing is a significant overhead of heavy batches. The kernel tries to make this as cheap as possible by avoiding as much work as possible, but to be truly lazy requires userspace to construct its batches and relocation trees in a convenient manner for processing. Kristian made an attempt to enable libdrm_intel to supply its execbuffers in this format, http://lists.freedesktop.org/archives/intel-gfx/2015-January/058550.html This is my batchmgr concept from that thread. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
