2015-09-01i915: Set ddi_pll_sel in DP MST pathAnder Conselvan de Oliveira
The DP MST encoder config function never sets ddi_pll_sel, even though its value is programmed in its ->pre_enable() hook. That used to work because a new pipe_config was kzalloc'ed at every modeset, and the value of zero selects the highest clock for the PLL. Starting with the commit below, the value of ddi_pll_sel is preserved through modesets, and since the correct value wasn't properly setup by the MST code, it could lead to warnings and blank screens. commit 8504c74c7ae48b4b8ed1f1c0acf67482a7f45c93 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Fri May 15 11:51:50 2015 +0300 drm/i915: Preserve ddi_pll_sel when allocating new pipe_config Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91628 Cc: stable@vger.kernel.org # 7e6313a2516d drm/i915: Don't use link_bw for PLL setup Cc: stable@vger.kernel.org Cc: Timo Aaltonen <tjaalton@ubuntu.com> Cc: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2015-09-01drm/i915: Preserve SSC earlierLukas Wunner
Commit 92122789b2d6 ("drm/i915: preserve SSC if previously set v3") added code to intel_modeset_gem_init to override the SSC status read from VBT with the SSC status set by BIOS. However, intel_modeset_gem_init is invoked *after* intel_modeset_init, which calls intel_setup_outputs, which *modifies* SSC status by way of intel_init_pch_refclk. So unlike advertised, intel_modeset_gem_init doesn't preserve the SSC status set by BIOS but whatever intel_init_pch_refclk decided on. This is a problem on dual gpu laptops such as the MacBook Pro which require either a handler to switch DDC lines, or the discrete gpu to proxy DDC/AUX communication: Both the handler and the discrete gpu may initialize after the i915 driver, and consequently, an LVDS connector may initially seem disconnected and the SSC therefore is disabled by intel_init_pch_refclk, but on reprobe the connector may turn out to be connected and the SSC must then be enabled. Due to 92122789b2d6 however, the SSC is not enabled on reprobe since it is assumed BIOS disabled it while in fact it was disabled by intel_init_pch_refclk. Also, because the SSC status is preserved so late, the preserved value only ever gets used on resume but not on panel initialization: intel_modeset_init calls intel_init_display which indirectly calls intel_panel_use_ssc via multiple subroutines, *before* the BIOS value overrides the VBT value in intel_modeset_gem_init (intel_panel_use_ssc is the sole user of dev_priv->vbt.lvds_use_ssc). Fix this by moving the code introduced by 92122789b2d6 from intel_modeset_gem_init to intel_modeset_init before the invocation of intel_setup_outputs and intel_init_display.

This also aligns with our future plans to unify more the runtime and system suspend/resume paths.

2015-08-31drm/exynos: Enable atomic modesetting featureGustavo Padovan
From: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Now that atomic modesetting is implemented for exynos enable the DRIVER_ATOMIC flag on the driver's features. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2015-08-31drm/exynos: remove wait queue for pending page flipGustavo Padovan
Exynos atomic commit procedures already does this job of waiting for pending updates to finish, that means using pending_flip_queue is pointless now because the disable CRTC procedure will never happen during a page_flip.

2015-08-31drm/exynos: wait all planes updates to finishGustavo Padovan
Add infrastructure to wait for all planes updates to finish by using an atomic_t variable to track how many pending updates we are waiting plus a wait_queue for the wait part. It also changes vblank behaviour and keeps it enabled for all types of updates Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2015-08-31drm/exynos: add atomic asynchronous commitGustavo Padovan
The atomic modesetting interfaces supports async commits that should be implemented by the drivers. If drm core requests an async commit exynos_atomic_commit() will now schedule a work task to run the update later. It also serializes commits that needs to run on the same crtc, putting the following commit to wait until the current one is finished.

2015-08-31drm/exynos: fimd: only finish update if START == START_SGustavo Padovan
fimd_update_plane() programs BUF_START[win] and during the update BUF_START[win] is copied to BUF_START_S[win] (its shadow register) and starts scanning out, then it raises a irq. The fimd_irq_handler, in the case we have a pending_fb, will check the fb value was copied to START_S register and finish the update in case of success.

2015-08-31drm/exynos: add macro to get the address of START_S regGustavo Padovan
This macro is need to get the value of the START shadow register, that will tell if an framebuffer is currently displayed on the screen or not. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2015-08-31drm/exynos: check for pending fb before finish updateGustavo Padovan
The current code was ignoring the end of update for all overlay planes, caring only for the primary plane update in case of pageflip. This change adds a change to start to check for pending updates for all planes through exynos_plane->pending_fb. At the start of plane update the pending_fb is set with the fb to be shown on the screen. Then only when to fb is already presented in the screen we set pending_fb to NULL to signal that the update was finished.

2015-08-31drm/exynos: fimd: move window protect code to prepare/cleanup_planeGustavo Padovan
Only set/clear the update bit in the CRTC's .atomic_begin()/flush() so all planes are really committed at the same time. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2015-08-31drm/exynos: add prepare and cleanup phases for planesGustavo Padovan
From: Gustavo Padovan <gustavo.padovan@collabora.co.uk> .prepare_plane() and .cleanup_plane() allows to perform extra operations before and after the update of planes. For FIMD for example this will be used to enable disable the shadow protection bit. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
