From ae6c4806927b8b0781ecc187aa16b10c820fc430 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 6 Aug 2014 15:04:53 +0200 Subject: [PATCH] drm/i915: Only track real ppgtt for a context MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There's a bit a confusion since we track the global gtt, the aliasing and real ppgtt in the ctx->vm pointer. And not all callers really bother to check for the different cases and just presume that it points to a real ppgtt. Now looking closely we don't actually need ->vm to always point at an address space - the only place that cares actually has fixup code already to decide whether to look at the per-proces or the global address space. So switch to just tracking the ppgtt directly and ditch all the extraneous code. v2: Fixup the ppgtt debugfs file to not oops on a NULL ctx->ppgtt. Also drop the early exit - without aliasing ppgtt we want to dump all the ppgtts of the contexts if we have full ppgtt. v3: Actually git add the compile fix.
