Also use TMDS char rate validation callback to filter out modes, instead of hardcoding 4k@30.

2024-10-12drm/bridge: tc358767: Fix link properties discoveryTomi Valkeinen
When a display controller driver uses DRM_BRIDGE_ATTACH_NO_CONNECTOR, tc358767 will behave properly and skip the creation of the connector. However, tc_get_display_props(), which is used to find out about the DP monitor and link, is only called from two places: .atomic_enable() and tc_connector_get_modes(). The latter is only used when tc358767 creates its own connector, i.e. when DRM_BRIDGE_ATTACH_NO_CONNECTOR is _not_ set. Thus, the driver never finds out the link properties before get_edid() is called. With num_lanes of 0 and link_rate of 0 there are not many valid modes... Fix this by adding tc_get_display_props() call at the beginning of get_edid(), so that we have up to date information before looking at the modes.

2024-10-11drm/vmwgfx: Stop using dev_private to store driver data.Maaz Mombasawala
Currently vmwgfx uses the dev_private opaque pointer in drm_device to store driver data in vmw_private struct. Using dev_private is deprecated, and the recommendation is to embed struct drm_device in the larger per-device structure. The vmwgfx driver already embeds struct drm_device in its struct vmw_private, so switch to using that exclusively and stop using dev_private.

2024-10-11accel/ivpu: Prevent recovery invocation during probe and resumeKarol Wachowski
Refactor IPC send and receive functions to allow correct handling of operations that should not trigger a recovery process. Expose ivpu_send_receive_internal(), which is now utilized by the D0i3 entry, DCT initialization, and HWS initialization functions. These functions have been modified to return error codes gracefully, rather than initiating recovery. The updated functions are invoked within ivpu_probe() and ivpu_resume(), ensuring that any errors encountered during these stages result in a proper teardown or shutdown sequence. The previous approach of triggering recovery within these functions could lead to a race condition, potentially causing undefined behavior and kernel crashes due to null pointer dereferences.

2024-10-11accel/ivpu: Make DB_ID and JOB_ID allocations incrementalTomasz Rusinowicz

Also allow to pass DRIVER_DATE on build time to allow versioning the driver in case it is built out of the tree.

2024-10-11accel/ivpu: Add FW state dump on TDRTomasz Rusinowicz
Send JSM state dump message at the beginning of TDR handler. This allows FW to collect debug info in the FW log before the state of the NPU is lost allowing to analyze the cause of a TDR. Wait a predefined timeout (10 ms) so the FW has a chance to write debug logs. We cannot wait for JSM response at this point because IRQs are already disabled before TDR handler is invoked.
