From: Ben Widawsky Date: Wed, 14 Aug 2013 09:38:36 +0000 (+0200) Subject: drm/i915: Convert execbuf code to use vmas X-Git-Tag: next-20130919~37^2~98 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=27173f1f95db5e74ceb35fe9a2f2f348ea11bac9;p=karo-tx-linux.git drm/i915: Convert execbuf code to use vmas In order to transition more of our code over to using a VMA instead of an pair - we must have the vma accessible at execbuf time. Up until now, we've only had a VMA when actually binding an object. The previous patch helped handle the distinction on bound vs. unbound. This patch will help us catch leaks, and other issues before we actually shuffle a bunch of stuff around. This attempts to convert all the execbuf code to speak in vmas. Since the execbuf code is very self contained it was a nice isolated conversion. The meat of the code is about turning eb_objects into eb_vma, and then wiring up the rest of the code to use vmas instead of obj, vm pairs. Unfortunately, to do this, we must move the exec_list link from the obj structure. This list is reused in the eviction code, so we must also modify the eviction code to make this work. WARNING: This patch makes an already hotly profiled path slower. The cost is unavoidable. In reply to this mail, I will attach the extra data. v2: Release table lock early, and two a 2 phase vma lookup to avoid having to use a GFP_ATOMIC.
