Danilo Krummrich authored
So far the DRM GPUVA manager offers common infrastructure to track GPU VA allocations and mappings, generically connect GPU VA mappings to their backing buffers and perform more complex mapping operations on the GPU VA space. However, there are more design patterns commonly used by drivers, which can potentially be generalized in order to make the DRM GPUVA manager represent a basic GPU-VM implementation. In this context, this patch aims at generalizing the following elements. 1) Provide a common dma-resv for GEM objects not being used outside of this GPU-VM. 2) Provide tracking of external GEM objects (GEM objects which are shared with other GPU-VMs). 3) Provide functions to efficiently lock all GEM objects dma-resv the GPU-VM contains mappings of. 4) Provide tracking of evicted GEM objects the GPU-VM contains mappings of, such that validation of evicted GEM objects is accelerated. 5) Provide some convinience functions for common patterns. Rather than being designed as a "framework", the target is to make all features appear as a collection of optional helper functions, such that drivers are free to make use of the DRM GPUVA managers basic functionality and opt-in for other features without setting any feature flags, just by making use of the corresponding functions.

The JDI LPM102A188A is a 2560x1800 IPS panel found in the Google Pixel C.

Add the device link when panel bridge is attached and delete the link when panel bridge is detached. The drm device is the consumer while the panel device is the supplier. This makes sure that the drm device suspends eariler and resumes later than the panel device, hence resolves problems where the order is reversed, like the problematic case mentioned in the below link.

atomic_get_input_bus_fmts is only implemented for LVDS decoders, resulting that LVDS encoders only support bus format MEDIA_BUS_FMT_FIXED. This results in warnings like: mxsfb 21c8000.lcdif: Bridge does not provide bus format, assuming MEDIA_BUS_FMT_RGB888_1X24. Please fix bridge driver by handling atomic_get_input_bus_fmts. Fix this by reusing lvds_codec_atomic_get_input_bus_fmts currently used for LVDS decoders. Use RGB888_1X24 for LVDS encoders.
