The i915.modeset parameter doesn't really provide any useful benefit over the nomodeset kernel parameter. Anything that i915.modeset does can be achieved via nomodeset or not probing i915 at all. Unfortunately, the i915.modeset parameter is widely referenced on various forums, and removing it is not that simple. Start off by deprecating it in the module parameter documentation, and logging a warning message on non-default values. Cc: Daniel Veter <daniel.vetter@ffwll.ch> Reviewed-by:

Since commit b30324ad ("drm/i915: Deprecated UMS support") we've silently failed the probe, without propagating errors, on nomodeset and i915.modeset=0. This has been to not upset userspace. See the above commit for details. Since then, we've removed both the UMS and KMS kconfig options in commit 03dae59c ("drm/i915: Ditch UMS config option") and commit fd930478 ("drm/i915: Remove KMS Kconfig option") respectively. Another ten years or so have passed. Continue with the deprecation by actually failing the probe with nomodeset and i915.modeset=0. Cc: Daniel Veter <daniel.vetter@ffwll.ch> Reviewed-by:

In order to better handle the necessary DSB DEwake tricks let's switch over to using a chained DSB for the actual LUT programming. The CPU will start 'dsb_color_commit', which in turn will start the chained 'dsb_color_vblank'. Signed-off-by:

We'll soon utilize several DSBs during the commit. To that end rename the current crtc_state->dsb to crtc_state->dsb_color_vblank to better reflect its role (color managemnent stuff programmed during vblank). Signed-off-by:

In order to avoid the DSB keeping the DEwake permanently asserted we must clear DSB_PMCTRL_2.DSB_FORCE_DEWAKE once we are done. For good measure do the same for DSB_PMCTRL.DSB_ENABLE_DEWAKE. Experimentally this doens't seem to be actually necessary (unlike with DSB_FORCE_DEWAKE). That is, the DSB_ENABLE_DEWAKE doesn't seem to do anything whenever the DSB is not active. But I'd hate to waste a ton of power in case there I'm wrong and there is some way DEwake could remaing asserted. One extra register write is a small price to pay for some peace of mind.

Allow intel_dsb_chain() to start the chained DSB at start of the undelaye vblank. This is slightly more involved than simply setting the bit as we must use the DEwake mechanism to eliminate pkgC latency. And DSB_ENABLE_DEWAKE itself is problematic in that it allows us to configure just a single scanline, and if the current scanline is already past that DSB_ENABLE_DEWAKE won't do anything, rendering the whole thing moot. The current workaround involves checking the pipe's current scanline with the CPU, and if it looks like we're about to miss the configured DEwake scanline we set DSB_FORCE_DEWAKE to immediately assert DEwake. This is somewhat racy since the hardware is making progress all the while we're checking it on the CPU. We can make things less racy by chaining two DSBs and handling the DSB_FORCE_DEWAKE stuff entirely without CPU involvement: 1. CPU starts the first DSB immediately 2. First DSB configures the second DSB, including its dewake_scanline 3. First DSB starts the second w/ DSB_WAIT_FOR_VBLANK 4. First DSB asserts DSB_FORCE_DEWAKE 5. First DSB waits until we're outside the dewake_scanline-vblank_start window 6. First DSB deasserts DSB_FORCE_DEWAKE That will guarantee that the we are fully awake when the second DSB starts to actually execute. Signed-off-by:

In order to handle the DEwake tricks without involving the CPU we need a mechanism by which one DSB can start another one. Add a basic function to do so. We'll extend it later with additional code to actually deal with DEwake. Signed-off-by:

Ville Syrjälä authored
Add functions to emit a DSB scanline window wait instructions. We can either wait for the scanline to be IN the window or OUT of the window. The hardware doesn't handle wraparound so we must manually deal with it by swapping the IN range to the inverse OUT range, or vice versa. Also add a bit of paranoia to catch the edge case of waiting for the entire frame. That doesn't make sense since an IN wait would be a nop, and an OUT wait would imply waiting forever. Most of the time this also results in both scanline ranges (original and inverted) to have lower=upper+1 which is nonsense from the hw POV. For now we are only handling the case where the scanline wait happens prior to latching the double buffered registers during the commit (which might change the timings due to LRR/VRR/etc.) Signed-off-by:

Adjust the code that determines the correct DSB_CHICKEN value to be usable for use within DSB commands themselves. Ie. precompute it based on our knowledge of what the hardware state (VRR vs. not mainly) will be at the time of the commit. Signed-off-by:
-
Ville Syrjälä authored
When determining various scanlines for DSB use we should take into account whether VRR is active at the time when the DSB uses said scanline information. For now all DSB scanline usage occurs prior to the actual commit, so we only need to care about the state of VRR at that time. I've decided to move intel_crtc_scanline_to_hw() in its entirety to the DSB code as it will also need to know the actual state of VRR in order to do its job 100% correctly. TODO: figure out how much of this could be moved to some more generic place and perhaps be shared with the CPU vblank evasion code/etc... Signed-off-by: -

Currently we calculate the DEwake scanline based on the delayed vblank start, while in reality it should be computed based on the undelayed vblank start (as that is where the DSB actually starts). Currently it doesn't really matter as we don't have any vblank delay configured, but that may change in the future so let's be accurate in what we do. We can also remove the max() as intel_crtc_scanline_to_hw() can deal with negative numbers, which there really shouldn't be anyway. Signed-off-by:

Relocate intel_dsb_dewake_scanline() and dsb_chicken() upwards in the file. I need to reuse these while emitting DSB commands, and I'd like to keep the DSB command emission stuff more or less grouped together in the file. Also drop the intel_ prefix from intel_dsb_dewake_scanline() since it's all internal stuff and thus doesn't need so much namespacing. Signed-off-by:

Ville Syrjälä authored
Currently we switch from out software idea of a scanline to the hw's idea of a scanline during the commit phase in _intel_dsb_commit(). While that is slightly easier due to fastsets fiddling with the timings, we'll also need to generate proper hw scanline numbers already when emitting DSB scanline wait instructions. So this approach won't do in the future. Switch to hw scanline numbers earlier. Also intel_dsb_dewake_scanline() itself already makes some assumptions about VRR that don't take into account VRR toggling during fastsets, so technically delaying the sw->hw conversion doesn't even help us. The other reason for delaying the conversion was that we are using intel_get_crtc_scanline() during intel_dsb_commit() which gives us the current sw scanline. But this is pretty low level stuff anyway so just using raw PIPEDSL reads seems fine here, and that of course gives us the hw scanline directly, reducing the need to do so many conversions. v2: Return the non-hw scanline from intel_dsb_dewake_scanline() Reviewed-by:

On ilk/snb the pipe may be configured to place the LUT before or after the CSC depending on various factors, but as there is only one LUT (no split mode like on IVB+) we only advertise a gamma_lut and no degamma_lut in the uapi to avoid confusing userspace. This can cause a problem during readout if the VBIOS/GOP enabled the LUT in the pre CSC configuration. The current code blindly assigns the results of the readout to the degamma_lut, which will cause a failure during the next atomic_check() as we aren't expecting anything to be in degamma_lut since it's not visible to userspace. Fix the problem by assigning whatever LUT we read out from the hardware into gamma_lut.
