The drm_copy_field() function copies strings into userspace buffers, so the first parameter needs to have a __user annotation to avoid warnings from the sparse checker. Signed-off-by:

Not enough brown paper bags, you'll have to share one. (oops below). The initial match condition code was racy (locking is coming I hear). then along came: cd234b0b drm/i915: Do not dereference NULL crtc or fb until after checking Chris made an attempt to fix it, Ben "reviewed" it. Daniel merged it. Then drm/i915: Make use of intel_fb_obj() (v2) 2ff8fde1 made it worse by removing the obj check later. All in all, my laptop can't barely turn off the display without hitting this. Posted to #intel-gfx out of niceness, but I've merged this already into drm-next. Here's an oops.

drm_plane_init() (the legacy plane initialization function) takes a bool as its final parameter; originally this indicated whether a plane was 'private' to the driver (before the DRM core understood non-overlay planes), now it indicates whether the plane is a primary plane (private planes were used by some drivers to represent primary planes internally). The newer drm_universal_plane_init() take an 'enum drm_plane_type' as its final parameter to allow the caller to specify the specific plane type desired (primary, cursor, or overlay). Due to a rebasing mistake, the primary plane helper is currently passing DRM_PLANE_TYPE_PRIMARY (enum value = 1) for drm_plane_init()'s boolean 'is_primary' parameter. This winds up giving the correct behavior since DRM_PLANE_TYPE_PRIMARY evaluates as true, but is confusing to anyone reading the code since we're passing an enum value (one of three possible values) for a boolean parameter. Replace the primary plane helper's call to drm_plane_init() with drm_universal_plane_init() so that the parameter and value types match up as expected. Signed-off-by:

We may reach this point while the machine is still runtime suspended, so we'll hit a WARN. The other encoders also don't touch registers at this point, so instead of waking the machine up, write some code to keep the register always at the same state, including after we runtime suspend/resume.

Daniel Vetter authored
To be able to do this we need to separately keep track of how many crtcs need a given WRPLL and how many actually actively use it. The common shared dpll framework already has all this, including massive state readout and cross checking. Which allows us to do this switch in a fairly small patch. Reviewed-by:
-
Daniel Vetter authored
Mostly this patch is one big excersize in deleting code and asserts which are no longer needed. Note that we still abuse the shared dpll framework a bit since we call the enable/disable functions from the crtc mode_set and off hooks. But changing the actual hardware sequence will be done in the next step. Note that besides the massive amount of changes in this patch the places and order in which the low-level WRPLL code is called is absolutely unchanged. Signed-off-by:

Just filing in names and ids, but not yet officially registering them so that the hw state cross checker doesn't completely freak out about them. Still since we do already read out and cross check config->shared_dpll the basics are now there to flesh out the wrpll shared dpll implementation. The idea is now to roll out all the callbacks step-by-step and then at the end switch to the shared dpll framework. This way hw and sw changes are clearly separated. Signed-off-by:

To make things a bit more manageable extract a new function for reading out common ddi port state. This means a bit of duplication between encoders and the core since both look at the same registers, but doesn't seem worth to make a fuzz about. We can also remove the state readout code in intel_ddi_setup_hw_pll_state. That code is only called from the hardware take over and not the cross check code, and only after the crtc state is reconstructed. So we can rely on an accurate value of crtc->config.ddi_pll_sel already. Compared to the old code also trust the hw state more and don't special-case port A - we want to cross-check the actual-state, not bake in our own assumptions about how this is supposed to all be linked up. v2: Make use of the read-out ddi_pll_sel in intel_ddi_clock_get.
