2020-11-18drm/i915/dp: Master/Slave enable/disable sequence for bigjoinerManasi Navare
Enabling is done in a special sequence and so should plane updates be. Ideally the end user never notices the second pipe is used. This way ideally everything will be tear free, and updates are really atomic as userspace expects it. This uses generic modeset_enables() calls like trans port sync but still has special handling for disable since for slave we should not disable things like encoder, plls that are not enabled for slave.

2020-11-18drm/i915: Try to make bigjoiner work in atomic checkMaarten Lankhorst
When the clock is higher than the dotclock, try with 2 pipes enabled. If we can enable 2, then we will go into big joiner mode, and steal the adjacent crtc. This only links the crtc's in software, no hardware or plane programming is done yet.

When doing the plane state copy from the UV plane to the Y plane let's just copy the hw state directly instead of using the original uapi state.

2020-11-17drm/i915: Tweaked Wa_14010685332 for PCHs used on gen11 platformsBob Paauwe
The WA specifies that we need to toggle a SDE chicken bit on and then off as the final step in preparation for s0ix entry. Bspec: 33450 Bspec: 8402 However, something is happening after we toggle the bit that causes the WA to be invalidated. This makes dispcnlunit1_cp_xosc_clkreq active being already in s0ix state i.e SLP_S0 counter incremented. Tweaking the Wa_14010685332 by setting the bit on suspend and clearing it on resume turns down the dispcnlunit1_cp_xosc_clkreq. B.Spec has Documented this tweaked sequence of WA as an alternative. Let keep this tweaked WA for Gen11 platforms and keep untweaked WA for other platforms which never observed this issue. v2 (MattR): - Change the comment on the workaround to give PCH names rather than platform names. Although the bspec is setup to list workarounds by platform, the hardware team has confirmed that the actual issue being worked around here is something that was introduced back in the Cannon Lake PCH and carried forward to subsequent PCH's. - Extend the untweaked version of the workaround to include PCH_CNP as well. Note that since PCH_CNP is used to represent CMP, this will apply on CML and some variants of RKL too. - Cap the untweaked version of the workaround so that it won't apply to "fake" PCH's (i.e., DG1). The issue we're working around really is an issue in the PCH itself, not the South Display, so it shouldn't apply when there isn't a real PCH. v3: - use intel_de_rmw().

2020-11-17drm/i915: Handle max_bpc==16Ville Syrjälä
EDID can declare the maximum supported bpc up to 16, and apparently there are displays that do so. Currently we assume 12 bpc is tha max. Fix the assumption and toss in a MISSING_CASE() for any other value we don't expect to see. This fixes modesets with a display with EDID max bpc > 12. Previously any modeset would just silently fail on platforms that didn't otherwise limit this via the max_bpc property. In particular we don't add the max_bpc property to HDMI ports on gmch platforms, and thus we would see the raw max_bpc coming from the EDID. I suppose we could already adjust this to also allow 16bpc, but seeing as no current platform supports that there is little point.

2020-11-16drm/i915: Use actual readout results for .get_freq()Ville Syrjälä
Currently the DPLL .get_freq() uses pll->state.hw_state which is not the thing we actually read out (except during driver load/resume). Outside of that pll->state.hw_state is just the thing we committed last time around. During state check we just read the thing into crtc_state->dpll_hw_state, so that is what we should use for calculating the DPLL output frequency. I think we used to do this so that the results of the readout were actually used, but somehow it got changed when the .get_freq() refactoring happened.

Store the relative data rate for planes in the crtc state so that we don't have to use intel_atomic_crtc_state_for_each_plane_state() to compute it even for the planes that are no part of the current state. Should probably just nuke this stuff entirely an use the normal plane data rate instead. The two are slightly different since this relative data rate doesn't factor in the actual pixel clock, so it's a bit odd thing to even call a "data rate".

2020-11-15drm/i915: Nuke intel_atomic_crtc_state_for_each_plane_state() from skl+ wm codeVille Syrjälä
intel_atomic_crtc_state_for_each_plane_state() peeks at the plane's current state without holding the plane's mutex, trusting that the crtc's mutex will protect it. In practice that does work since our planes can't move between pipes, but it sets a bad example. intel_atomic_crtc_state_for_each_plane_state() also relies on crtc_state.uapi.plane_mask which may be full of lies when it comes to the bigjoiner stuff, so soon we can't use it as is anyway. So best to just get rid of it entirely. Which we can easily do by switching to the g4x/vlv "raw" watermark approach. Later on we should even be able to move the "raw" watermark computation into the normal .plane_check() code, leaving only the merging/clamping of the final watermarks to the later stages. But that will require adjusting the ilk+ wm code similarly as well.

DG1 uses 2 registers for the ddi clock mapping, with PHY A and B using DPCLKA_CFGCR0 and PHY C and D using DPCLKA1_CFGCR0. Hide this behind a single macro that chooses the correct register according to the phy being accessed, use the correct bitfields for each pll/phy and implement separate functions for DG1 since it doesn't share much with ICL/TGL anymore. The previous values were correct for PHY A and B since they were using the same register as before and the bitfields were matching. v2: Add comment and try to simplify DG1_DPCLKA* macros by reusing previous ones v3: - Fix DG1_DPCLKA_CFGCR0_DDI_CLK_SEL_MASK() after wrong macro reuse - Move phy -> id map to a separate macro (Aditya) - Remove DG1_DPCLKA_CFGCR0_DDI_CLK_SEL_MASK where not required (Aditya) - Use drm_WARN_ON Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Clinton Taylor <Clinton.A.Taylor@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Aditya Swarup <aditya.swarup@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Aditya Swarup <aditya.swarup@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201106210006.837953-1-lucas.demarchi@intel.com
