2013-07-01drm/nv50-/vm: take mutex rather than irqsave spinlockBen Skeggs
These operations can take quite some time, and we really don't want to have to hold a spinlock for too long. Now that the lock ordering for vm and the gr/nv84 hw bug workaround has been reversed, it's possible to use a mutex here. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Feature summary: Add S3C64XX SoC series support - S3C64XX SoC series are previous version chips of Exynos SoC series. With this patch set, KMS driver of Exynos drm supports those chips also. Update device tree support - This patch set corrects compatible strings, and adds Exynos5420 SoC support for hdmi subsystem. Consider CCF (Common Clock Framework) support - With reference to CCF support, it uses clock_prepare_enable/clock_disable_unprepare instead of clk_enable/clk_disable for hdmi subsystem.

2013-06-28drm/i915: fix the "ghost eDP" encoder unwind pathPaulo Zanoni
Because calling intel_dp_encoder_destroy inside intel_edp_init_connector is just wrong. This is the initialization path, so we should properly unwind all the initialization through the whole caller stack. On the intel_dp_encoder_destroy function we do the following: 1 - Call i2c_del_adapter 2 - Call drm_encoder_cleanup 3 - If edp: 3.1 - Cancel panel_vdd_work 3.2 - Call ironlake_panel_vdd_of_sync 4 - Free the encoder And here is how we unwind each specific step: 1 - We have intel_dp_init_connector -> intel_dp_i2c_init -> i2c_dp_aux_add_bus -> i2c_add_adapter, so we call i2c_del_dapter at intel_dp_init_connector 2 - Call it in the same function that called drm_encoder_init 3 - Call it in the same function that called INIT_DELAYED_WORK 4 - Free it in the same function that allocated it Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Reviewed-by: Zoltan Nyul <zoltan.nyul@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-06-28drm/i915: propagate errors from intel_dp_init_connectorPaulo Zanoni
In case we detect a "ghost eDP", intel_edp_init_connector frees both the connector and encoder and then returns. On Haswell, intel_ddi_init then tries to use the freed encoder on the HDMI initialization path since the following commit: commit 21a8e6a4853b2ed39fa4c5188a710f2cf1b92026 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Apr 10 23:28:35 2013 +0200 drm/i915: don't setup hdmi for port D edp in ddi_init So now on intel_ddi_init we check for the "ghost eDP" case and return without trying to initialize HDMI.

2013-06-28drm/i915: don't check encoder at DP connector destroy()Paulo Zanoni
By the time we call intel_dp_destroy (which destroys the connector) the encoder may have been destroyed already, so if we use it we may be reading some free memory. That happens in drm_mode_config_cleanup() and also inside intel_dp_init_connector() when we detect a ghost eDP. I also hope this may solve some random memory bugs. Reported by kmemcheck.
