2018-07-13drm/i915/psr: Remove few mod parameters option.Rodrigo Vivi2-11/+1
Reduce the module parameter to enable or disable. The link stand by vs full link off was used only once. And it was actually masking another bug fixed by commit '84bb2916a683 ("drm/i915/psr: Check for SET_POWER_CAPABLE bit at PSR init time.")' So, let's remove these options for now. End goal is to fully remove the mod param, moving it to a debugfs interface in upcoming patches.

2018-07-13drm/i915: Use crtc_state->has_psr instead of CAN_PSR for pipe updateTarun Vyas3-3/+8
In commit "drm/i915: Wait for PSR exit before checking for vblank evasion", the idea was to limit the PSR IDLE checks when PSR is actually supported. While CAN_PSR does do that check, it doesn't applies on a per-crtc basis. crtc_state->has_psr is a more granular check that only applies to pipe(s) that have PSR enabled. Without the has_psr check, we end up waiting on the eDP transcoder's PSR_STATUS register irrespective of whether the pipe being updated is driving it or not. v2: Remove unnecessary parantheses, make checkpatch happy. v3: Move the has_psr check to intel_psr_wait_for_idle and commit message changes (DK). v4: Derive dev_priv from intel_crtc_state (DK) v5: Commit message changes to reflect the HW behavior (DK) Fixes: a608987970b9 ("drm/i915: Wait for PSR exit before checking for vblank evasion") Reviewed-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Signed-off-by: Tarun Vyas <tarun.vyas@intel.com> Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180712053323.26266-1-tarun.vyas@intel.com

2018-07-12drm/sun4i: tcon-top: Fix return type warningMaxime Ripard1-1/+1
When commit af11942ee44e ("drm/sun4i: tcon-top: Cleanup clock handling") was merged, the error handling path of the of_property_match_string was changed to take into account the fact that the returned value of that function wasn't an error pointer but an error code. Unfortunately, this introduced a warning since the now returned value is an integer, while the sun8i_tcon_top_register_gate function should return an error pointer. Fix that by calling ERR_PTR.

2018-07-12drm/sun4i: Implement zpos for DE2Jernej Skrabec4-37/+72
Initial implementation of DE2 planes only supported fixed zpos. Expand implementation with configurable zpos property. Implementation background: Channel in DE2 driver represents one DRM plane, whereas pipe is just mapped channel to known Z position. Pipe 0 will always be at the bottom, pipe 1 just above pipe 0 and so on. If, for example, channel 1 is mapped at pipe 0 and channel 0 at pipe 1, whatever is on channel 0 will appear on top. Before this commit, channel id was used for addressing channel related registers (prefixed with SUN8I_MIXER_CHAN_UI_ or SUN8I_MIXER_CHAN_VI_) and pipe registers (prefixed with SUN8I_MIXER_BLEND_). Additionally, register SUN8I_MIXER_BLEND_ROUTE, which takes care for mapping channels to pipes had fixed value. It mapped channel 0 to pipe 0, 1 to 1 and so on. Consequence of all that was fixed Z order of planes. With this commit, pipe registers are using zpos property as index and channel related registers still use channel id as index. Pipe mapping register is now set dynamically too and pipe enable register is rebuild every time to make sure only active pipes are enabled. Testing was done to confirm that there is no issues if bottom plane contains pixels with alpha value < 0xff and if it doesn't whole screen.

Since: 0d4b78b3d2c0 ("drm/i915/guc: Assert we have the doorbell before setting it up") We have asserts in GuC doorbell related functions, which is a good thing. Unfortunately, we were using those to check whether GuC FW is refusing to allocate invalid doorbell - which makes the test fail. Well, it would make the test WARN, except we fumbled cleanup ordering and eat the BUG_ON instead. Let's keep the asserts and use the internal implementation in the test.

Currently, TCON supports 2 ways to match TCON with engine (mixer in this case). Old way is to just traverse of graph backwards and compare node pointer. New way is to match TCON and engine by their respective ids. All SoCs with DE2 enabled till now used the old way, which means mixer id was never used and thus never implemented. However, for R40, only the new way will be used. To prepare for that, implement mixer id fetching from DT.

2018-07-12drm/vkms: Add vblank events simulated by hrtimersRodrigo Siqueira3-0/+119
This commit adds regular vblank events simulated through hrtimers, which is a feature required by VKMS to mimic real hardware. Additionally, all the vblank event send after pageflip is kept in the atomic_flush function. Changes since V1: - Compute the vblank timer interval per interruption Ville Syrjälä and Daniel Vetter: - Removes hardcoded vblank interval to get it from user space Changes since V2: Chris Wilson - Removes unnecessary algorithm to compute the next period Daniel Vetter: - Uses drm_calc_timestamping_constants to get the vblank interval instead of calculating it manually - Adds disable_vblank helper that turns of crtc - Simplifies implementation by using drm_crtc_arm_vblank_event - Replaces the code in atomic_begin to atomic_flush - Removes unnecessary field in vkms_output Changes since V3: Daniel Vetter: - Squash "drm/vkms: Add atomic helpers functions" into the commit that handling vblank events simulated by hrtimers Signed-off-by: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/7709bba40782ec06332d57fff337797b272581fc.1531359228.git.rodrigosiqueiramelo@gmail.com

2018-07-11drm/client: Fix: drm_client_new: Don't require DRM to be registeredNoralf Trønnes1-10/+1
Commit 894a677f4b3e ("drm/cma-helper: Use the generic fbdev emulation") broke almost all drivers that use the CMA helper. The reason is that drm_client_new() requires that the DRM device has been registered, but the drivers register fbdev before registering DRM. Remove the requirement that DRM should be registered when creating a new client.

ICL changes the registers and addresses to 64 bits.
