When roll over detected for seq_num_m, we shouldn't continue with stream management with rolled over value. So we are terminating the stream management retry, on roll over of the seq_num_m. v2: using drm_dbg_kms instead of DRM_DEBUG_KMS [Anshuman] v3: dev_priv is used as i915 [JaniN] v4: roll over is detected at the start of the stream management.

As per the HDCP2.2 compliance test 1B-10 expectation, when stream management for a repeater fails, we retry thrice and when it fails in all retries, HDCP2.2 reauthentication aborted at kernel. v2: seq_num_m++ is extended for steam management failures too.[Anshuman] v3: use drm_dbg_kms instead of DRM_DEBUG_KMS [Anshuman] v4: dev_priv is used as i915 [JaniN] v5: Few improvisements are done [Sean] Signed-off-by:

Since we now have proper old and new cdclk state we no longer need to keep this flag to indicate that the force min cdclk has changed. Instead just check if the old vs. new value are different. Signed-off-by:

For platforms that can't do native 4:2:0 outout we may still be able to do it by getting the DP->HDMI protocol converter to perform the 4:4:4->4:2:0 downsamling for us. In this case we have to configure our hardware to output YCbCr 4:4:4, which we've already hooked up so all we need to do is flip the switch. Signed-off-by:

Pull the "do we want to enable audio?" computation into a small helper to make intel_hdmi_compute_config() less messy. Will make it easier to add more checks for this later (eg. we should actually be checking at the hblank is long enough for audio transmission). Signed-off-by:

Since we store a pointer to the fake iommu device that is allocated on the stack, as soon as we leave the function it goes out of scope and any future dereference is undefined behaviour. Just in case we may need to look at the fake iommu device after initialiation, move the allocation from the stack into the data.
