2016-01-15drm/fb_cma_helper: Remove implicit call to disable_unused_functionsMaxime Ripard
The drm_fbdev_cma_init function always calls the drm_helper_disable_unused_functions. Since it's part of the usual probe process, all the drivers using that helper will end up having their encoder and CRTC disable functions called at probe if their device has not been reported as enabled. This could be fixed by reading out from the registers the current state of the device if it is enabled, but even that will not handle the case where the device is actually disabled. Moreover, the drivers using the atomic modesetting expect that their enable and disable callback to be called when the device is already enabled or disabled (respectively). We can however fix this issue by moving the call to drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the drivers needing it (all the drivers calling drm_fbdev_cma_init and not using the atomic modesetting) explicitly call it.

We need to set the DC FLUSH PIPE_CONTROL bit on Gen7+ to guarantee that writes performed via the HDC are visible in memory.

2016-01-14drm/vmwgfx: Fix a width / pitch mismatch on framebuffer updatesThomas Hellstrom
When the framebuffer is a vmwgfx dma buffer and a proxy surface is created, the vmw_kms_update_proxy() function requires that the proxy surface width and the framebuffer pitch are compatible, otherwise display corruption occurs as seen in gnome-shell/native with software 3D. Since the framebuffer pitch is determined by user-space, allocate a proxy surface the width of which is based on the framebuffer pitch rather than on the framebuffer width.

2016-01-13drm: Do not set connector->encoder in driversThierry Reding
An encoder is associated with a connector by the DRM core as a result of setting up a configuration. Drivers using the atomic or legacy helpers should never set up this link, even if it is a static one. While at it, try to catch this kind of error in the future by adding a WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't cover all the cases, since drivers could set this up after attaching. Drivers that use the atomic helpers will get a warning later on, though, so hopefully the two combined cover enough to help people avoid this in the future.

Identically to vfuncs interrupt mask initialization can also be compacted for more readable code.

2016-01-13drm/i915: Extract vfunc setup from logical ring initializersTvrtko Ursulin
Majority of them was duplicated code and only render ring currently overrides some of them. We can save some lines of code and also take away the confusion on why bsd2 did not do the seqno coherency workaround. (VCS2 ring does not exist on platforms where workaround is needed but that was not documented in the code.)

2016-01-13drm/i915/gen8: Factor out display interrupt handlingTvrtko Ursulin
Tidy quite long interrupt service routine by factoring out the display part. This simplifies the exit path a little bit, makes the code a bit more readable, and potentialy makes code reuse in the future easier.

2016-01-13drm/i915/gen8: Tidy display interrupt processingTvrtko Ursulin
One bugfix and a few tidy-ups: * Pipe fault logging was broken on Gen9+. * Removed some unnecessary local variables. * Removed unnecessary initializers. * Decreased pipe iir block indentation level. * Grouped variable initialization close to use sites.

2016-01-13drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1 pageMichel Thierry
Kernel and userspace are able to handle 4GB (1<<32) address space range, but "A32 Stateless Model" is not. According to documentation, A32 accesses are based on General State Base Address and bound checking is in place. Because size field (instruction State Base Address) limitation, it is not possible to address full 4GB memory region. A32 Stateless Model is used by some libraries and without this patch, the last page of 4GB address space is not accessible in 32bit processes.
