Currently eDP population is done at msm_dp_modeset_init() which happen at binding time. Move eDP population to be done at display probe time so that probe deferral cases can be handled effectively. wait_for_hpd_asserted callback is added during drm_dp_aux_init() to ensure eDP's HPD is up before proceeding eDP population. Changes in v5: -- inline dp_display_auxbus_population() and delete it Changes in v4: -- delete duplicate initialize code to dp_aux before drm_dp_aux_register() -- delete of_get_child_by_name(dev->of_node, "aux-bus") and inline the function -- not initialize rc = 0 Changes in v3: -- add done_probing callback into devm_of_dp_aux_populate_bus() Signed-off-by:

EV_HPD_INIT_SETUP flag is used to trigger the initialization of external DP host controller. Since external DP host controller initialization had been incorporated into pm_runtime_resume(), this flag became obsolete. msm_dp_irq_postinstall() which triggers EV_HPD_INIT_SETUP event is obsoleted accordingly. Changes in v4: -- reworded commit text -- drop EV_HPD_INIT_SETUP -- drop msm_dp_irq_postinstall() Changes in v3: -- drop EV_HPD_INIT_SETUP and msm_dp_irq_postinstall() Signed-off-by:

Currently DP driver is executed independent of PM runtime framework. This leads msm eDP panel can not being detected by edp_panel driver during generic_edp_panel_probe() due to AUX DPCD read failed at edp panel driver. Incorporate PM runtime framework into DP driver so that host controller's power and clocks are enable/disable through PM runtime mechanism. Once PM runtime framework is incorporated into DP driver, waking up device from power up path is not necessary. Hence remove it. After incorporating pm_runtime framework into eDP/DP driver, dp_pm_suspend() to handle power off both DP phy and controller during suspend and dp_pm_resume() to handle power on both DP phy and controller during resume are not necessary. Therefore both dp_pm_suspend() and dp_pm_resume() are dropped and replace with dp_pm_runtime_suspend() and dp_pm_runtime_resume() respectively. Changes in v9: -- silent compiler warning message at dp_power_init() and dp_power_deinit() with W1 flag Changes in v7: -- add comments to dp_pm_runtime_resume() -- add comments to dp_bridge_hpd_enable() -- delete dp->hpd_state = ST_DISCONNECTED from dp_bridge_hpd_notify() Changes in v6: -- delete dp_power_client_deinit(dp->power); -- remove if (!dp->dp_display.is_edp) condition checkout at plug_handle() -- remove if (!dp->dp_display.is_edp) condition checkout at unplug_handle() -- add IRQF_NO_AUTOEN to devm_request_irq() -- add enable_irq() and disable_irq() to pm_runtime_resume()/suspend() -- del dp->hpd_state = ST_DISCONNECTED from dp_bridge_hpd_disable() Changes in v5: -- remove pm_runtime_put_autosuspend feature, use pm_runtime_put_sync() -- squash add pm_runtime_force_suspend()/resume() patch into this patch Changes in v4: -- reworded commit text to explain why pm_framework is required for edp panel -- reworded commit text to explain autosuspend is choiced -- delete EV_POWER_PM_GET and PM_EV_POWER_PUT from changes #3 -- delete dp_display_pm_get() and dp_display_pm_Put() from changes #3 -- return value from pm_runtime_resume_and_get() directly -- check return value of devm_pm_runtime_enable() -- delete pm_runtime_xxx from dp_display_remove() -- drop dp_display_host_init() from EV_HPD_INIT_SETUP -- drop both dp_pm_prepare() and dp_pm_compete() from this change -- delete ST_SUSPENDED state -- rewording commit text to add more details regrading the purpose of this change Changes in v3: -- incorporate removing pm_runtime_xx() from dp_pwer.c to this patch -- use pm_runtime_resume_and_get() instead of pm_runtime_get() -- error checking pm_runtime_resume_and_get() return value -- add EV_POWER_PM_GET and PM_EV_POWER_PUT to handle HPD_GPIO case -- replace dp_pm_suspend() with pm_runtime_force_suspend() -- replace dp_pm_resume() with pm_runtime_force_resume() Signed-off-by:

Original both parser->parse() and dp_power_client_init() are done at dp_display_bind() since eDP population is done at binding time. In the preparation of having eDP population done at probe() time, move both function from dp_display_bind() to dp_display_probe(). Changes in v6: -- move dp_power_client_deinit() to remove() Changes in v5: -- explain why parser->parse() and dp_power_client_init() are moved to probe time -- tear down sub modules if failed Changes in v4: -- split this patch out of "incorporate pm_runtime framework into DP driver" patch Signed-off-by:

Currently the dp_display_request_irq() is executed at msm_dp_modeset_init() which ties irq registering to the DPU device's life cycle, while depending on resources that are released as the DP device is torn down. Move register DP driver irq handler to dp_display_probe() to have dp_display_irq_handler() IRQ tied with DP device. In addition, use platform_get_irq() to retrieve irq number from platform device directly. Changes in v5: -- reworded commit text as review comments at change #4 -- tear down component if failed at dp_display_request_irq() Changes in v4: -- delete dp->irq check at dp_display_request_irq() Changes in v3: -- move calling dp_display_irq_handler() to probe Signed-off-by:

Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there are other connection paths: - a path that connects rotator block to the DDR. - a path that needs to be handled to ensure MDSS register access functions properly, namely the "reg bus", a.k.a the CPU-MDSS CFG interconnect. Describe these paths to allow using them in device trees and in the driver. [Konrad: rework for one vs two MDP paths, update examples] Reviewed-by:

Abhinav Kumar authored
It's certainly possible that for large resolutions a single DPU SSPP cannot process the image without exceeding the MDP clock limits but it can still process it in multirect mode because the source rectangles will get divided and can fall within the MDP clock limits. If the SSPP cannot process the image even in multirect mode, then it will be rejected in dpu_plane_atomic_check_pipe(). Hence try using multirect for resolutions which cannot be processed by a single SSPP without exceeding the MDP clock limits. changes in v2: - use crtc_state's adjusted_mode instead of mode - fix the UBWC condition to check maxlinewidth Signed-off-by:

The EXT_external_objects extension is a bit awkward as it doesn't pass explicit modifiers, leaving the importer to guess with incomplete information. In the case of vk (turnip) exporting and gl (freedreno) importing, the "OPTIMAL_TILING_EXT" layout depends on VkImageCreateInfo flags (among other things), which the importer does not know. Which unfortunately leaves us with the need for a metadata back-channel. The contents of the metadata are defined by userspace. The EXT_external_objects extension is only required to work between compatible versions of gl and vk drivers, as defined by device and driver UUIDs. v2: add missing metadata kfree v3: Rework to move copy_from/to_user out from under gem obj lock to avoid angering lockdep about deadlocks against fs-reclaim Signed-off-by: -

Until various PM devfreq/QoS and interconnect patches land, we could potentially trigger reclaim from gpu scheduler thread, and under enough memory pressure that could trigger a sort of deadlock. Eventually the wait will timeout and we'll move on to consider other GEM objects. But given that there is still a potential for deadlock/stalling, we should reduce the timeout to contain the damage.
