2023-08-30drm/amdkfd: use correct method to get clock under SRIOVHorace Chen
[What] Current SRIOV still using adev->clock.default_XX which gets from atomfirmware. But these fields are abandoned in atomfirmware long ago. Which may cause function to return a 0 value. [How] We don't need to check whether SR-IOV. For SR-IOV one-vf-mode, pm is enabled and VF is able to read dpm clock from pmfw, so we can use dpm clock interface directly. For multi-VF mode, VF pm is disabled, so driver can just react as pm disabled. One-vf-mode is introduced from GFX9 so it shall not have any backward compatibility issue.

2023-08-30drm/amd/display: Write flip addr to scratch reg for subvpAlvin Lee
[Description] SubVP needs to "calculate" the earliest in use META address by using the current primary / meta addresses, but this leads to a race condition where FW and driver can read/write the address at the same time and intermittently produce inconsistent address offsets. To mitigate this issue without locking (too slow), save each surface flip addr into scratch registers and use this to keep track of the earliest in use META addres.

[Why&How] DMUB subsystem was continuing to use compile time offset calculation for register access. Switch this to runtime calculation to stay consistent with rest of DC code. To enable this, an additional interface init_reg_offsets() are added to DMUB's hw_funcs struct. Asics with runtime register offset calculation enabled shall populate this hook with a fn pointer that will invoke the necessary macros to calculate the offset.

2023-08-30drm/amd/display: PQ regamma end pointKrunoslav Kovac
[WHY & HOW] PQ has a fixed range of 0-10,000 nits. Using 1=80 nits normalization, PQ should map to 1.0 for X=125.0 HW LUT used for interpolation does not have X=125 so it's interpolated. However, we cap Y to 1 for all X>=125. The closest larger HW point is 128. What we want is Y(128) such that interpolation through 125 gives 1.0. Such value is ~1.00256. Another change is to hardcode PQ table, we pretty much always have 1=80 normalization so the table can be static.

2023-08-30drm/amd/display: PQ tail accuracyKrunoslav Kovac
[WHY & HOW] HW LUTs changed slightly in DCN3: 256 base+slope pairs were replaced by 257 bases. Code was still calculating all 256 base+slope and then creating 257th pt as last base + last slope. This was done in wrong format, and then "fixed" it by making the last two points the same thus making the last slope=0. However, this also created some precision problems near the end that are not visible but they do show up with capture cards. Solution is to calculate 257 and remove deltas since we no longer have those HW registers.

2023-08-29drm: Add initial ci/ subdirectoryTomeu Vizoso
Developers can easily execute several tests on different devices by just pushing their branch to their fork in a repository hosted on gitlab.freedesktop.org which has an infrastructure to run jobs in several runners and farms with different devices. There are also other automated tools that uprev dependencies, monitor the infra, and so on that are already used by the Mesa project, and we can reuse them too. Also, store expectations about what the DRM drivers are supposed to pass in the IGT test suite. By storing the test expectations along with the code, we can make sure both stay in sync with each other so we can know when a code change breaks those expectations. Also, include a configuration file that points to the out-of-tree CI scripts. This will allow all contributors to drm to reuse the infrastructure already in gitlab.freedesktop.org to test the driver on several generations of the hardware.

2023-08-29drm/i915/sdvo: Rework DDC bus handlingVille Syrjälä
Each SDVO device can have up to three sets of DDC pins. Currently we just register a single i2c_adapter for the entire SDVO device and semi-randomly pick the "correct" set of DDC pins during intel_sdvo_tmds_sink_detect(). This doesn't make any real sense especially if we have multiple outputs each with their own dedicated DDC bus. Let's clean up this mess and register a dedicated i2c_adapter for each of the possible pin pairs. Each output (ie. connector) can then pick the correct i2c_adapter to use for its DDC bus. And we can just switch over to drm_connector_init_with_ddc() to take care of the connector->ddc association, which also populates the "ddc" sysfs symlink as a bonus. And now that things are based on the actual connector we can also nuke the sketchy sdvo->controller_output thing.
