2023-07-11drm/client: Send hotplug event after registering a clientThomas Zimmermann
Generate a hotplug event after registering a client to allow the client to configure its display. Remove the hotplug calls from the existing clients for fbdev emulation. This change fixes a concurrency bug between registering a client and receiving events from the DRM core. The bug is present in the fbdev emulation of all drivers. The fbdev emulation currently generates a hotplug event before registering the client to the device. For each new output, the DRM core sends an additional hotplug event to each registered client. If the DRM core detects first output between sending the artificial hotplug and registering the device, the output's hotplug event gets lost. If this is the first output, the fbdev console display remains dark. This has been observed with amdgpu and fbdev-generic. Fix this by adding hotplug generation directly to the client's register helper drm_client_register(). Registering the client and receiving events are serialized by struct drm_device.clientlist_mutex. So an output is either configured by the initial hotplug event, or the client has already been registered. The bug was originally added in commit 6e3f17ee73f7 ("drm/fb-helper: generic: Call drm_client_add() after setup is done"), in which adding a client and receiving a hotplug event switched order. It was hidden, as most hardware and drivers have at least on static output configured. Other drivers didn't use the internal DRM client or still had struct drm_mode_config_funcs.output_poll_changed set. That callback handled hotplug events as well. After not setting the callback in amdgpu in commit 0e3172bac3f4 ("drm/amdgpu: Don't set struct drm_driver.output_poll_changed"), amdgpu did not show a framebuffer console if output events got lost. The bug got copy-pasted from fbdev-generic into the other fbdev emulation.

Instead of modifying the device info on the fly, use static const mock device info. It's not okay to modify device info at runtime; we've added separate runtime info for info that needs to be modified at runtime. We've added safeguards to device info to prevent it from being modified, but commit 5e352e32aec2 ("drm/i915: preparation for using PAT index") just cast the const away and modified it anyway.

2023-06-30drm/amd/display: Fix the delta clamping for shaper LUTHarry Wentland
The shaper LUT requires a 10-bit value of the delta between segments. We were using dc_fixpt_clamp_u0d10() to do that but it doesn't do what we want it to do. It will preserve 10-bit precision after the decimal point, but that's not quite what we want. We want 14-bit precision and discard the 4 most-significant bytes. To do that we'll do dc_fixpt_clamp_u0d14() & 0x3ff instead.
