2019-06-13drm: Add helpers to kick off self refresh mode in driversSean Paul4-0/+68
This patch adds a new drm helper library to help drivers implement self refresh. Drivers choosing to use it will register crtcs and will receive callbacks when it's time to enter or exit self refresh mode. In its current form, it has a timer which will trigger after a driver-specified amount of inactivity. When the timer triggers, the helpers will submit a new atomic commit to shut the refreshing pipe off. On the next atomic commit, the drm core will revert the self refresh state and bring everything back up to be actively driven. From the driver's perspective, this works like a regular disable/enable cycle. The driver need only check the 'self_refresh_active' state in crtc_state. It should initiate self refresh mode on the panel and enter an off or low-power state. Changes in v2: - s/psr/self_refresh/ (Daniel) - integrated the psr exit into the commit that wakes it up (Jose/Daniel) - made the psr state per-crtc (Jose/Daniel) Changes in v3: - Remove the self_refresh_(active|changed) from connector state (Daniel) - Simplify loop in drm_self_refresh_helper_alter_state (Daniel) - Improve self_refresh_aware comment (Daniel) - s/self_refresh_state/self_refresh_data/ (Daniel) Changes in v4: - Move docbook location below panel (Daniel) - Improve docbook with references and more detailed explanation (Daniel) - Instead of register/unregister, use init/cleanup (Daniel) Changes in v5: - Resolved conflict in drm_atomic_helper.c #include block - Resolved conflict in rst with HDCP helper docs Changes in v6: - Fix include ordering, clean up forward declarations (Sam) Link to v1: https://patchwork.freedesktop.org/patch/msgid/20190228210939.83386-2-sean@poorly.run Link to v2: https://patchwork.freedesktop.org/patch/msgid/20190326204509.96515-1-sean@poorly.run Link to v3: https://patchwork.freedesktop.org/patch/msgid/20190502194956.218441-6-sean@poorly.run Link to v4: https://patchwork.freedesktop.org/patch/msgid/20190508160920.144739-6-sean@poorly.run Link to v5: https://patchwork.freedesktop.org/patch/msgid/20190611160844.257498-6-sean@poorly.run Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Jose Souza <jose.souza@intel.com> Cc: Zain Wang <wzz@rock-chips.com> Cc: Tomasz Figa <tfiga@chromium.org> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Sam Ravnborg <sam@ravnborg.org> Tested-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190612145026.191846-1-sean@poorly.run
2019-06-13drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_stateSean Paul1-1/+1
Everyone who implements connector_helper_funcs->atomic_check reaches into the connector state to get the atomic state. Instead of continuing this pattern, change the callback signature to just give atomic state and let the driver determine what it does and does not need from it. Eventually all atomic functions should do this, but that's just too much busy work for me.

2019-06-13drm: Add atomic variants for bridge enable/disableSean Paul1-0/+106
This patch adds atomic variants for all of pre_enable/enable/disable/post_disable bridge functions. These will be called from the appropriate atomic helper functions. If the bridge driver doesn't implement the atomic version of the function, we will fall back to the vanilla implementation. Note that some drivers call drm_bridge_disable directly, and these cases are not covered. It's up to the driver to decide whether to implement both atomic_disable and disable, or if it's not necessary.

Add functions to the atomic core to retrieve the old and new connectors associated with an encoder in a drm_atomic_state. This is useful for encoders and bridges that need to access the connector, for instance for the drm_display_info. The CRTC associated with the encoder can also be retrieved through the connector state, and from it, the old and new CRTC states.

2019-06-13drm: Add atomic variants of enable/disable to encoder helper funcsSean Paul1-0/+49
This patch adds atomic_enable and atomic_disable callbacks to the encoder helpers. This will allow encoders to make informed decisions in their start-up/shutdown based on the committed state. Aside from the new hooks, this patch also introduces the new signature for .atomic_* functions going forward. Instead of passing object state (well, encoders don't have atomic state, but let's ignore that), we pass the entire atomic state so the driver can inspect more than what's happening locally. This is particularly important for the upcoming self refresh helpers.

2019-06-11drm: bridge: dw-hdmi: Add hook for resumeDouglas Anderson1-0/+2
On Rockchip rk3288-based Chromebooks when you do a suspend/resume cycle: 1. You lose the ability to detect an HDMI device being plugged in. 2. If you're using the i2c bus built in to dw_hdmi then it stops working. Let's add a hook to the core dw-hdmi driver so that we can call it in dw_hdmi-rockchip in the next commit. NOTE: the exact set of steps I've done here in resume come from looking at the normal dw_hdmi init sequence in upstream Linux plus the sequence that we did in downstream Chrome OS 3.14. Testing show that it seems to work, but if an extra step is needed or something here is not needed we could improve it. As part of this change we'll refactor the hardware init bits of dw-hdmi to happen all in one function and all at the same time. Since we need to init the interrupt mutes before we request the IRQ, this means moving the hardware init earlier in the function, but there should be no problems with that. Also as part of this we now unconditionally init the "i2c" parts of dw-hdmi, but again that ought to be fine.

2019-06-04drm/fb-helper: Remove drm_fb_helper_crtcNoralf Trønnes2-8/+30
struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so use that directly instead and attach it as a modeset array onto drm_client_dev. drm_fb_helper will use this array to store its modesets which means it will always initialize a drm_client, but it will not register the client (callbacks) unless it's the generic fbdev emulation. Code will later be moved to drm_client, so add code there in a new file drm_client_modeset.c with MIT license to match drm_fb_helper.c. The modeset connector array size is hardcoded for the cloned case to avoid having to pass in a value from the driver. A value of 8 is chosen to err on the safe side. This means that the max connector argument for drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore, a todo entry for this is added. In pan_display_atomic() restore_fbdev_mode_force() is used instead of restore_fbdev_mode_atomic() because that one will later become internal to drm_client_modeset. Locking order: 1. drm_fb_helper->lock 2. drm_master_internal_acquire 3. drm_client_dev->modeset_mutex v6: Improve commit message (Sam Ravnborg) v3: - Use full drm_client_init/release for the modesets (Daniel Vetter) - drm_client_for_each_modeset: use lockdep_assert_held (Daniel Vetter) - Hook up to Documentation/gpu/drm-client.rst (Daniel Vetter) v2: - Add modesets array to drm_client (Daniel Vetter) - Use a new file for the modeset code (Daniel Vetter) - File has to be MIT licensed (Emmanuel Vadot) - Add copyrights from drm_fb_helper.c Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190531140117.37751-3-noralf@tronnes.org
