Please split this patch into smaller parts: 1) split the bigjoiner/uncompressed joiners readouts 2) add more asserts relevant for bigjoiner/uncompressed joiner 3..n) bigjoiner stuff > + > + for_each_intel_crtc_in_pipe_mask(&dev_priv->drm, crtc, > + joiner_pipes(dev_priv)) { > + enum intel_display_power_domain power_domain; > + enum pipe pipe = crtc->pipe; > + intel_wakeref_t wakeref; > + > + power_domain = intel_dsc_power_domain(crtc, (enum transcoder) pipe); > with_intel_display_power_if_enabled(dev_priv, power_domain, wakeref) { > u32 tmp = intel_de_read(dev_priv, ICL_PIPE_DSS_CTL1(pipe)); > > - if (tmp & UNCOMPRESSED_JOINER_PRIMARY) > + if (!(tmp & ULTRA_JOINER_ENABLE)) > + continue; > + > + /* > + * As of now we always assume primary master to be PIPE A. > + * Otherwise we need a new field in crtc_state to track > + * primary master as well. > + */ > + drm_WARN(&dev_priv->drm, > + (tmp & PRIMARY_ULTRA_JOINER_ENABLE) && crtc->pipe != PIPE_A, > + "Ultrajoiner primary master isn't PIPE A(pipe %c)", > + pipe_name(crtc->pipe)); This feels rather misplaced. I think all the asserts should be in the caller. Could also write it more like this: WARN((ultrajoiner_primaries & possible_ultrajoiner_primaries()) != 0) which makes it trivial to add more pipes to the set of possible ultrajoiner primaries in the future. > + > + if (tmp & PRIMARY_ULTRA_JOINER_ENABLE) > *primary_pipes |= BIT(pipe); > - if (tmp & UNCOMPRESSED_JOINER_SECONDARY) > + else > *secondary_pipes |= BIT(pipe); > } > } > +} > > - /* Joiner pipes should always be consecutive primary and secondary */ > - drm_WARN(&dev_priv->drm, *secondary_pipes != *primary_pipes << 1, > - "Joiner misconfigured (primary pipes 0x%x, secondary pipes 0x%x)\n", > - *primary_pipes, *secondary_pipes); > +static void enabled_joiner_pipes(struct drm_i915_private *dev_priv, > + u8 *primary_pipes, u8 *secondary_pipes, > + bool *ultrajoiner_used) > +{ > + u8 primary_uncompressed_joiner_pipes, primary_bigjoiner_pipes; > + u8 primary_ultrajoiner_pipes; > + u8 secondary_uncompressed_joiner_pipes, secondary_bigjoiner_pipes; > + u8 secondary_ultrajoiner_pipes; > + u8 ultrajoiner_pipes, bigjoiner_pipes; > + > + enabled_uncompressed_joiner_pipes(dev_priv, &primary_uncompressed_joiner_pipes, > + &secondary_uncompressed_joiner_pipes); > + > + enabled_bigjoiner_pipes(dev_priv, &primary_bigjoiner_pipes, > + &secondary_bigjoiner_pipes); > + > + enabled_ultrajoiner_pipes(dev_priv, &primary_ultrajoiner_pipes, > + &secondary_ultrajoiner_pipes); > + > + *primary_pipes = 0; > + *secondary_pipes = 0; > + *ultrajoiner_used = primary_ultrajoiner_pipes && secondary_ultrajoiner_pipes; > + ultrajoiner_pipes = primary_ultrajoiner_pipes | secondary_ultrajoiner_pipes; > + bigjoiner_pipes = primary_bigjoiner_pipes | secondary_bigjoiner_pipes; > + > + drm_WARN(&dev_priv->drm, > + (ultrajoiner_pipes & bigjoiner_pipes) == ultrajoiner_pipes, != > + "Ultrajoiner/Bigjoiner misconfigured:" > + "Ultrajoiner pipes: 0x%x(primary) 0x%x(secondary)," > + "Bigjoiner pipes: 0x%x(primary) 0x%x(secondary)", > + primary_ultrajoiner_pipes, secondary_ultrajoiner_pipes, > + primary_bigjoiner_pipes, secondary_bigjoiner_pipes); Some additional checks we could have: Make sure the ultrajoiner primaries are also bigjoiner primaries: WARN((ultrajoiner_primaries & bigjoiner_primaries) != ultrajoiner_primaries) Make sure bigjoiner and uncompressed joiner don't conflict: WARN((uncompressed_pipes & bigjoiner_pipes) != 0); And something validate that the ultrajoiner primaries vs. secondaries are correct, Basically the same as what we already had for bigjoiner and uncompressed joiner, but constructing the expected secondaries from the primaries is a bit move involved than the simple <<1 we used in those cases. I guess we could have something like this to generate the secondaries masks from the primaries masks: expected_secondaries(primaries, num_pipes) { secondaries = 0; for (i = 1 ; i < num_pipes; i++) secondaries |= primaries << i; return secondaries; } and then we could write all those checks like so: WARN(bigjoiner_secondaries != expected_secondaries(bigjoiner_primaries, 2)); WARN(uncompressed_secondaries != expected_secondaries(uncompressed_primaries, 2)); WARN(ultrajoiner_secondaries != expected_secondaries(ultrajoiner_primaries, 4)); And we should probably also check for conflicts between each primary and secondary masks: WARN((foo_secondaries & foo_primaries) != 0); Only really possible with uncompressed joiner due to the way the bits work, but no real harm in asserting it for all the joiner types. > + > + *primary_pipes = primary_uncompressed_joiner_pipes | primary_bigjoiner_pipes | > + primary_ultrajoiner_pipes;
