Hi,

Here's some patches to enable the HDR output in the RPi4 HDMI controller.

This needed a quite intrusive rework in the first patch to allow a CRTC to have access to the whole DRM state at atomic_enable / atomic_disable time.

Let me know what you think, Maxime

Changes from v1: - Added the coccinelle script to the first patch - Fixed the pixel_rate ramp up

Maxime Ripard (6): drm/atomic: Pass the full state to CRTC atomic enable/disable drm/vc4: hvs: Align the HVS atomic hooks to the new API drm/vc4: Pass the atomic state to encoder hooks drm/vc4: hdmi: Create a custom connector state drm/vc4: hdmi: Store pixel frequency in the connector state drm/vc4: hdmi: Enable 10/12 bpc output

New subject: [PATCH v2 1/6] drm/atomic: Pass the full state to CRTC atomic enable/disable

If the CRTC driver ever needs to access the full DRM state, it can't do so at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state will have cleared the pointer from the struct drm_crtc_state to the struct drm_atomic_state before calling those hooks.

In order to allow that, let's pass the full DRM state to atomic_enable and atomic_disable. The conversion was done using the coccinelle script below, built tested on all the drivers and actually tested on vc4.

Since the CRTC setup in vc4 is split between the PixelValves/TXP and the HVS, only the PV/TXP atomic hooks were updated in the previous commits, but it makes sense to update the HVS ones too.

New subject: [PATCH v2 5/6] drm/vc4: hdmi: Store pixel frequency in the connector state

The pixel rate is for now quite simple to compute, but with more features (30 and 36 bits output, YUV output, etc.) will depend on a bunch of connectors properties.

Let's store the rate we have to run the pixel clock at in our custom connector state, and compute it in atomic_check.

Something appears to be slightly off with this one. Running the monitor (Dell U2718Q 4k monitor) at 1080p60.

Use modetest to switch "max bpc" to 10bpc, and the monitor reports 1080p48. Use modetest to switch "max bpc" to 12bpc, and the monitor reports 1080p40. I haven't got an HDMI analyser to hand to confirm whether we're actually putting out 10 or 12bpc.

So at a guess a clock is unaltered, but the number of bits being sent over the link is increased, thereby dropping the overall frame rate. Having tested with the firmware it only points to my monitor not supporting alternate bpc values - not so helpful.

I'm not sure the handling of the GCP is correct either. It is enabled/disabled via bit 0 of HDMI_RAM_PACKET_CONFIG in the same way all the infoframes are. The firmware enables/disables sending the GCP when handling avmute, but this driver isn't handling avmute so it never gets enabled

I'll have a further experiment to see if I can make things play ball. I'll need to collect the analyser and deep colour display to really try it out.
