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.

2023-07-10drm/bridge: cdns-mhdp8546: Fix the interrupt enable/disableNikhil Devshatwar
When removing the tidss driver, there is a warning reported by kernel about an unhandled interrupt for mhdp driver. [ 43.238895] irq 31: nobody cared (try booting with the "irqpoll" option) ... [snipped backtrace] [ 43.330735] handlers: [ 43.333020] [<000000005367c4f9>] irq_default_primary_handler threaded [<000000007e02b601>] cdns_mhdp_irq_handler [cdns_mhdp8546] [ 43.344607] Disabling IRQ #31 This happens because as part of cdns_mhdp_bridge_hpd_disable, driver tries to disable the interrupts. While disabling the SW_EVENT interrupts, it accidentally enables the MBOX interrupts, which are not handled by the driver. Fix this with a read-modify-write to update only required bits. Use the enable / disable function as required in other places.

2023-07-10drm/tidss: Update encoder/bridge chain connect modelAradhya Bhatia
With the new encoder/bridge chain model, the display controller driver is required to create a drm_connector entity instead of asking the bridge to do so during drm_bridge_attach. Moreover, the controller driver should create a drm_bridge entity to negotiate bus formats and a 'simple' drm_encoder entity to expose it to userspace. Update the encoder/bridge initialization sequence in tidss as per the new model.

2023-07-10drm/i915: Don't rely that 2 VDSC engines are always enough for pixel rateStanislav Lisovskiy
We are currently having FIFO underruns happening for kms_dsc test case, problem is that, we check if curreny cdclk is >= pixel rate only if there is a single VDSC engine enabled(i.e dsc_split=false) however if we happen to have 2 VDSC engines enabled, we just kinda rely that this would be automatically enough. However pixel rate can be even >= than VDSC clock(cdclk) * 2, so in that case even with 2 VDSC engines enabled, we still need to tweak it up. So lets compare pixel rate with cdclk * VDSC engine count and check if it still requires bumping up. Previously we had to bump up CDCLK many times for similar reasons. v2: - Use new intel_dsc_get_num_vdsc_instances to determine number of VDSC engines, instead of slice count(Ankit Nautiyal) v3: - s/u8/int/ (Jani Nikula) v4: - Remove slice count mentions(Ankit Nautiyal) - Use DIV_ROUND_UP in order to make sure that resulting CDCLK would be always >= than required, after division(Ankit Nautiyal) Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230704131758.14024-3-stanislav.lisovskiy@intel.com
