2019-08-16drm/i915: Extract intel_frontbuffer active trackingChris Wilson1-3/+0
Move the active tracking for the frontbuffer operations out of the i915_gem_object and into its own first class (refcounted) object. In the process of detangling, we switch from low level request tracking to the easier i915_active -- with the plan that this avoids any potential atomic callbacks as the frontbuffer tracking wishes to sleep as it flushes.

2019-07-23drm/tinydrm: Move tinydrm_spi_transfer()Noralf Trønnes2-6/+0
This is only used by mipi-dbi drivers so move it there. The reason this isn't moved to the SPI subsystem is that it will in a later patch pass a dummy rx buffer for SPI controllers that need this. Low memory boards (64MB) can run into a problem allocating such a "large" contiguous buffer on every transfer after a long up time. This leaves a very specific use case, so we'll keep the function here. mipi-dbi will first go through a refactoring though, before this will be done. Remove SPI todo entry now that we're done with the tinydrm.ko SPI code. v2: Drop moving the mipi_dbi_spi_init() declaration (Sam) Cc: David Lechner <david@lechnology.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: : David Lechner <david@lechnology.com> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190719155916.62465-8-noralf@tronnes.org

2019-06-21drm/prime: Update docsDaniel Vetter1-36/+4
Yes this is a bit a big patch, but since it's essentially a complete rewrite of all the prime docs I didn't see how to better split it up. Changes: - Consistently point to drm_gem_object_funcs as the preferred hooks, where applicable. - Document all the hooks in &drm_driver that lacked kerneldoc. - Completely new overview section, which now also includes the cleaned up lifetime/reference counting subchapter. I also mentioned the weak references in there due to the lookup caches. - Completely rewritten helper intro section, highlight the import/export related functionality. - Polish for all the functions and more cross references. I also sprinkled a bunch of todos all over. Most important: 0 code changes in here. The cleanup motivated by reading and improving all this will follow later on. v2: Actually update the prime helper docs. Plus add a few FIXMEs that I won't address right away in subsequent cleanup patches. v3: - Split out the function moving. This patch is now exclusively documentation changes. - Typos and nits (Sam). v4: Polish suggestions from Noralf.

2019-06-13drm: Add helpers to kick off self refresh mode in driversSean Paul1-0/+9
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

All drivers add all their connectors so there's no need to keep around an array of available connectors. Instead we just put the useable (not writeback) connectors in a temporary array using drm_client_for_each_connector_iter() everytime we probe the outputs. Other places where it's necessary to look at the connectors, we just iterate over them using the same iterator function.

2019-06-04drm/fb-helper: Remove drm_fb_helper_crtcNoralf Trønnes2-0/+6
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.

2019-05-24drm/mcde: Add new driver for ST-Ericsson MCDELinus Walleij2-0/+9
This adds a new DRM driver for the ST-Ericsson Multi Channel Display Engine, MCDE display controller. This hardware has three independent DSI hosts and can composit and display several memory buffers onto an LCD display. It was developed for several years inside of ST-Ericsson and shipped with a few million mobile phones from Sony and Samsung, as well as with the Snowball community development board. The driver is currently pretty rudimentary but supports a simple framebuffer so we can get penguins and graphics when using these SoCs.

2019-05-16drm/doc: Document expectation that userspace review looks at kernel uAPI.Eric Anholt1-1/+3
The point of this review process is that userspace using the new uAPI can actually live with the uAPI being provided, and it's hard to know that without having actually looked into a kernel patch yourself.

2019-05-16drm/doc: Allow new UAPI to be used once it's in drm-next/drm-misc-next.Eric Anholt1-3/+3
I was trying to figure out if it was permissible to merge the Mesa side of V3D's CSD support yet while it's in drm-misc-next but not drm-next, and developers on #dri-devel IRC had differing opinions of what the requirement was. v2: Restrict to just drm-next or drm-misc-next on airlied's request.

2019-05-15drm: Integrate VRAM MM into struct drm_deviceThomas Zimmermann1-0/+6
There's now a pointer to struct drm_vram_mm stored in struct drm_device. DRM drivers that use VRAM MM should use this field to refer to their instance of the data structure. Appropriate helpers are now provided as well. Adding struct drm_vram_mm to struct drm_device further avoids wrappers and boilerplate code in drivers. This patch implements default functions for callbacks in struct drm_driver and struct file_operations that use the struct drm_vram_mm stored in struct drm_device. Drivers that need to provide their own implementations can still do so. The patch also adds documentation for the VRAM helper library in general. v5: * set .llseek to no_llseek() from DRM_VRAM_MM_FILE_OPERATIONS v4: * cleanups from checkpatch.pl * document VRAM helper library Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: http://patchwork.freedesktop.org/patch/msgid/20190508082630.15116-9-tzimmermann@suse.de Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2019-05-15drm: Add VRAM MM, a simple memory manager for dedicated VRAMThomas Zimmermann1-1/+12
The VRAM MM memory manager is a helper library that manages dedicated video memory of simple framebuffer devices. It is supported to be used with struct drm_gem_vram_object, but does not depend on it. The implementation is based on the respective code from ast, bochs, and mgag200. These drivers share the exact same implementation except for type names. The helpers are currently build with TTM. This may change in future revisions. v4: * cleanups from checkpatch.pl v2: * renamed to struct drm_vram_mm * add drm_vram_mm_mmap() helper * documentation fixes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: http://patchwork.freedesktop.org/patch/msgid/20190508082630.15116-7-tzimmermann@suse.de Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
