At the end of a commit, atomic helpers can generate a fake VBLANK event automatically. Originally implemented for writeback connectors, the functionality can be used by any driver and/or hardware without proper VBLANK interrupt. The patch updates the documentation to make this behaviour official: settings struct drm_crtc_state.no_vblank to true enables automatic generation of fake VBLANK events. The new interface drm_dev_has_vblank() returns true if vblanking has been initialized for a device, or false otherwise. Atomic helpers use this function when initializing no_vblank in the CRTC state in drm_atomic_helper_check_modeset(). If vblanking has been initialized for a device, no_blank is disabled. Otherwise it's enabled. Hence, atomic helpers will automatically send out fake VBLANK events with any driver that did not initialize vblanking. v5: * more precise documentation and commit message v4: * replace drm_crtc_has_vblank() with drm_dev_has_vblank() * add drm_dev_has_vblank() in this patch * move driver changes into separate patches v3: * squash all related changes patches into this patch Signed-off-by:

vmwgfx stopped using them. With the drm device model that we've slowly evolved over the past few years master status essentially controls access to display resources, and nothing else. Since that's a pure access permission check drivers should have no need at all to track additional state on a per file basis. Aside: For cleanup and restoring kernel-internal clients the grand plan is to move everyone over to drm_client and drm_master_internal_acquire/release, like the generic fbdev code already does. That should get rid of most ->lastclose implementations, and I think also subsumes any processing vmwgfx does in master_set/drop. Reviewed-by:

This patch adds a new DRM driver for Texas Instruments DSS IPs used on Texas Instruments Keystone K2G, AM65x, and J721e SoCs. The new DSS IP is a major change to the older DSS IP versions, which are supported by the omapdrm driver. While on higher level the Keystone DSS resembles the older DSS versions, the registers are completely different and the internal pipelines differ a lot. DSS IP found on K2G is an "ultra-light" version, and has only a single plane and a single output. The K3 DSS IPs are found on AM65x and J721E SoCs. AM65x DSS has two video ports, one full video plane, and another "lite" plane without scaling support. J721E has 4 video ports, 2 video planes and 2 lite planes. AM65x DSS has also an integrated OLDI (LVDS) output. Version history: v2: - rebased on top of drm-next-2019-11-27 - sort all include lines in all files - remove all include <drm/drmP.h> - remove select "select VIDEOMODE_HELPERS" - call dispc_vp_setup() later in tidss_crtc_atomic_flush() (there is no to call it in new modeset case as it is also called in vp_enable()) - change probe sequence and drm_device allocation (follow example in drm_drv.c) - use __maybe_unused instead of #ifdef for pm functions - remove "struct drm_fbdev_cma *fbdev;" from driver data - check panel connector type before connecting it v3: no change v4: no change v5: - remove fifo underflow irq handling, it is not an error and it should be used for debug purposes only - memory tuning, prefetch plane fifo up to high-threshold value to minimize possibility of underflows. v6: - Check CTM and gamma support from dispc_features when creating crtc - Implement CTM support for k2g and fix k3 CTM implementation - Remove gamma property persistence and always write color properties in a new modeset v7: - Fix checkpatch.pl --strict issues - Rebase on top of drm-misc-next-2020-01-10 v8: - Remove idle debug prints from dispc_init() - Add Reviewed-by: Benoit Parrot <bparrot@ti.com> v9: - Rename dispc_write_irqenable() to dispc_set_irqenable() to avoid conflict exported omapfb function with same name - Add Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Co-developed-by: -

Since drm_global_mutex is a true global mutex across devices, we don't want to acquire it unless absolutely necessary. For maintaining the device local open_count, we can use atomic operations on the counter itself, except when making the transition to/from 0. Here, we tackle the easy portion of delaying acquiring the drm_global_mutex for the final release by using atomic_dec_and_mutex_lock(), leaving the global serialisation across the device opens.

Chris Wilson authored
The file is not part of the global drm resource and can be released prior to take the global mutex to drop the open_count (and potentially close) the drm device. As the global mutex is indeed global, not only within the device but across devices, a slow file release mechanism can bottleneck the entire system. However, inside drm_close_helper() there are a number of dev->driver callbacks that take the drm_device as the first parameter... Worryingly some of those callbacks may be (implicitly) depending on the global mutex. v2: Drop the debug message for the open-count, it's included with the drm_file_free() debug message -- and for good measure make that up as reading outside of the mutex. v3: Separate the calling of the filp cleanup outside of drm_global_mutex into a new drm_release_noglobal() hook, so that we can phase the transition. drm/savage relies on the global mutex, and there may be more, so be cautious.

The issues caused by: commit 64e62bdf ("drm/dp_mst: Remove VCPI while disabling topology mgr") Prompted me to take a closer look at how we clear the payload state in general when disabling the topology, and it turns out there's actually two subtle issues here. The first is that we're not grabbing &mgr.payload_lock when clearing the payloads in drm_dp_mst_topology_mgr_set_mst(). Seeing as the canonical lock order is &mgr.payload_lock -> &mgr.lock (because we always want &mgr.lock to be the inner-most lock so topology validation always works), this makes perfect sense. It also means that -technically- there could be racing between someone calling drm_dp_mst_topology_mgr_set_mst() to disable the topology, along with a modeset occurring that's modifying the payload state at the same time. The second is the more obvious issue that Wayne Lin discovered, that we're not clearing proposed_payloads when disabling the topology. I actually can't see any obvious places where the racing caused by the first issue would break something, and it could be that some of our higher-level locks already prevent this by happenstance, but better safe then sorry. So, let's make it so that drm_dp_mst_topology_mgr_set_mst() first grabs &mgr.payload_lock followed by &mgr.lock so that we never race when modifying the payload state. Then, we also clear proposed_payloads to fix the original issue of enabling a new topology with a dirty payload state. This doesn't clear any of the drm_dp_vcpi structures, but those are getting destroyed along with the ports anyway.

Explicit management of the GPU's core stacks is only necessary in the case of a broken integration with the PDC. Since there are no known platforms which have such a broken integration let's remove the explicit control from the driver since this apparently causes problems on other platforms and will have a small performance penality. The out of tree mali_kbase driver contains this text regarding controlling the core stack (CONFIGMALI_CORESTACK): Enabling this feature on supported GPUs will let the driver powering on/off the GPU core stack independently without involving the Power Domain Controller. This should only be enabled on platforms which integration of the PDC to the Mali GPU is known to be problematic. This feature is currently only supported on t-Six and t-HEx GPUs. If unsure, say N.
