2020-01-31drm/bridge: Patch atomic hooks to take a drm_bridge_stateBoris Brezillon
This way the drm_bridge_funcs interface is consistent with the rest of the subsystem. The drivers implementing those hooks are patched too. v10: * Add changelog to the commit message v8 -> v9: * No changes v7: * Adjust things to the bridge_state changes v6: * Also fixed rcar-du/rcar_lvds.c same as analogix/analogix_dp_core.c v5: * No changes v4: * Rename func params into old_bridge_state * Add Laurent's Rb v3: * Old state clarification moved to a separate patch v2: * Pass the old bridge state Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> [narmstrong: renamed state as old_bridge_state in rcar_lvds_atomic_disable] Reviewed by: Jernej Skrabec <jernej.skrabec@siol.net> Tested-by: Jonas Karlman <jonas@kwiboo.se> Link: https://patchwork.freedesktop.org/patch/msgid/20200128135514.108171-5-boris.brezillon@collabora.com

2020-01-31drm/bridge: Add a drm_bridge_state objectBoris Brezillon
One of the last remaining objects to not have its atomic state. This is being motivated by our attempt to support runtime bus-format negotiation between elements of the bridge chain. This patch just paves the road for such a feature by adding a new drm_bridge_state object inheriting from drm_private_obj so we can re-use some of the existing state initialization/tracking logic. v10: * Add changelog to the commit message v9: * Clarify the fact that the bridge->atomic_reset() and {connector,plane,crtc,...}->reset() semantics are different * Move the drm_atomic_private_obj_init() call back to drm_bridge_attach() * Check the presence of ->atomic_duplicate_state instead of ->atomic_reset in drm_atomic_add_encoder_bridges() * Fix copy&paste errors in the atomic bridge state helpers doc * Add A-b/R-b tags v8: * Move bridge state helpers out of the CONFIG_DEBUGFS section v7: * Move helpers, struct-defs, ... to atomic helper files to avoid the drm -> drm_kms_helper -> drm circular dep * Stop providing default implementation for atomic state reset, duplicate and destroy hooks (has to do with the helper/core split) * Drop all R-b/T-b as helpers have now be moved to other places v6: * Made helpers private, removed doc and moved them to satisfy dependencies * Renamed helpers to _default_ v5: * Re-introduced the helpers from v4 v4: * Fix the doc * Kill default helpers (inlined) * Fix drm_atomic_get_bridge_state() to check for an ERR_PTR() * Add Neil's R-b v3: * No changes v2: * Use drm_for_each_bridge_in_chain() * Rename helpers to be more consistent with the rest of the DRM API * Improve/fix the doc Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200128135514.108171-2-boris.brezillon@collabora.com

2020-01-30drm: Initialize struct drm_crtc_state.no_vblank from device settingsThomas Zimmermann
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: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200129120531.6891-2-tzimmermann@suse.de
2020-01-29drm/auth: Drop master_create/destroy hooksDaniel Vetter
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.

2020-01-27drm/tidss: New driver for TI Keystone platform Display SubSystemJyri Sarha
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: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Jyri Sarha <jsarha@ti.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Benoit Parrot <bparrot@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Link: https://patchwork.freedesktop.org/patch/msgid/925fbfad58ff828e8e07fdff7073a0ee65750c3d.1580129724.git.jsarha@ti.com

2020-01-27drm/lima: support heap buffer creationQiang Yu
heap buffer is used as output of GP and input of PP for Mali Utgard GPU. Size of heap buffer depends on the task so is a runtime variable. Previously we just create a large enough buffer as heap buffer. Now we add a heap buffer type to be able to increase the backup memory dynamically when GP fail due to lack of heap memory.

2020-01-24drm: Avoid drm_global_mutex for simple inc/dec of dev->open_countChris Wilson
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.

2020-01-24drm: Release filp before global lockChris Wilson
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.
