From 91d181ddb310e7ad59da353263b7c35eaa6921b9 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Mon, 10 Feb 2014 18:42:49 +0200 Subject: [PATCH] drm/i915: vlv: handle only enabled pipestat interrupt events MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Atm we call the handlers for pending pipestat interrupt events even if they aren't explicitly enabled by i915_enable_pipestat(). This isn't an issue for events other than the vblank start event, since those are always enabled anyways. Otoh, we enable the vblank start event on-demand, so we'll end up calling the vblank handler at times when they are disabled. I haven't checked if this causes any real problem, but for consistency and to remove some overhead we should still fix this by clearing / handling only the enabled interrupt events. Also this is a dependency for the upcoming VLV power domain patchset where we need to disable all the pipestat interrupts whenever the display power well is off. v2: - inline the status->enable mask mapping (Ville) - don't check for invalid PSR bit on platforms other than VLV (Ville) Signed-off-by: Imre Deak Reviewed-by: Ville Syrjälä [danvet: Frob conflict due to different merge order.] Signed-off-by: Daniel Vetter --- Reading git-format-patch failed
