2020-02-27dma-buf: add dynamic DMA-buf handling v15Christian König
On the exporter side we add optional explicit pinning callbacks. Which are called when the importer doesn't implement dynamic handling, move notification or need the DMA-buf locked in place for its use case. On the importer side we add an optional move_notify callback. This callback is used by the exporter to inform the importers that their mappings should be destroyed as soon as possible. This allows the exporter to provide the mappings without the need to pin the backing store. v2: don't try to invalidate mappings when the callback is NULL, lock the reservation obj while using the attachments, add helper to set the callback v3: move flag for invalidation support into the DMA-buf, use new attach_info structure to set the callback v4: use importer_priv field instead of mangling exporter priv. v5: drop invalidation_supported flag v6: squash together with pin/unpin changes v7: pin/unpin takes an attachment now v8: nuke dma_buf_attachment_(map|unmap)_locked, everything is now handled backward compatible v9: always cache when export/importer don't agree on dynamic handling v10: minimal style cleanup v11: drop automatically re-entry avoidance v12: rename callback to move_notify v13: add might_lock in appropriate places v14: rebase on separated locking change v15: add EXPERIMENTAL flag, some more code comments Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/353993/?series=73646&rev=1

2020-02-27drm/virtio: add virtio_gpu_is_shmem helperGurchetan Singh
The plan is use have both shmem and virtual "vram" running side-by-side in virtio-gpu. It looks like we'll eventually use struct drm_gem_object as a base class, and we'll need to convert to shmem and vram objects on the fly. As a first step, add a virtio_gpu_is_shmem helper.

The only exception is the .get_modes() operation that is still invoked through the omap_dss_device-based pipeline. For the time being make the next bridge in the chain optional as the VENC output is still based on omap_dss_device.

As the drm_bridge for the HDMI encoder is unconditionally registered and attached, those operations will be called at the appropriate time. The omapdss device .set_infoframe() and .set_hdmi_mode() operations have no equivalent in drm_bridge. Thir content is thus moved to the bridge .enable() operation as the data they store is not needed before the HDMI encoder gets enabled.

2020-02-26drm/omap: hdmi5: Register a drm_bridge for EDID readLaurent Pinchart
In order to integrate with a chain of drm_bridge, the internal HDMI5 encoder has to expose the EDID read operation through the drm_bridge API. Register a bridge at initialisation time to do so. For the time being make the next bridge in the chain optional as the HDMI output is still based on omap_dss_device. The create_connector argument to the bridge attach function is also ignored for the same reason. This will be changed later when removing the related omapdrm-specific display drivers.

2020-02-26drm/omap: hdmi5: Rework EDID read to isolate data readLaurent Pinchart
In preparation of adding DRM bridge support to the hdmi5 encoder code, rework the EDID read to isolate data read. The hdmi_read_edid() function is the main entry point. It performs all initialisation steps required prior to reading the EDID (such as ensuring the device is powered on), as well as corresponding cleanup steps afterwards. EDID read itself is handled by hdmi_read_edid_data() that calls the hdmi5_core_ddc_read() function to read individual blocks. This new code architecture will allow reusing hdmi_read_edid() and hdmi5_core_ddc_read() for the drm_bridge EDID read implementation, while swapping out hdmi_read_edid_data() for the DRM drm_do_get_edid() function.

2020-02-26drm/omap: Add infrastructure to support drm_bridge local to DSS outputsLaurent Pinchart
In order to support drm_bridge-based pipeline, the internal HDMI encoders will need to expose the EDID read operation through the drm_bridge API, and thus to expose a drm_bridge instance corresponding to the encoder. The HDMI encoders are however handled as omap_dss_device instances, which conflicts with this requirement. In order to move forward with the drm_bridge transition, add support for creating drm_bridge instances local to DSS outputs. If a local bridge is passed to the omapdss_device_init_output() function, it is used as the first bridge in the chain, and the omap_dss_device.next_bridge field is set to the next bridge for the use of the internal encoders' bridges.

2020-02-26drm/omap: dss: Fix output next device lookup in DTLaurent Pinchart
The DSS core looks up the next device connected to an output by traversing the OF graph. It currently hardcodes the local port number to 0, which breaks any output with a different port number (SDI on OMAP3 and any DPI output but the first one). Fix this by repurposing the currently unused of_ports bitmask in omap_dss_device with an of_port output port number, and use it to traverse the OF graph.
