2020-12-02drm/i915/display: Enable HDR on gen9 devices with MCA LspconUma Shankar
Gen9 hardware supports HDMI2.0 through LSPCON chips. Extending HDR support for MCA LSPCON based GEN9 devices. SOC will drive LSPCON as DP and send HDR metadata as standard DP SDP packets. LSPCON will be set to operate in PCON mode, will receive the metadata and create Dynamic Range and Mastering Infoframe (DRM packets) and send it to HDR capable HDMI sink devices. v2: Re-used hsw infoframe write implementation for HDR metadata for LSPCON as per Ville's suggestion. v3: Addressed Jani Nikula's review comments. v4: Addressed Ville's review comments, removed redundant wrapper and checks, passed arguments instead of hardcodings.

2020-12-02drm/i915/display: Add HDR Capability detection for LSPCONUma Shankar
LSPCON firmware exposes HDR capability through LPCON_CAPABILITIES DPCD register. LSPCON implementations capable of supporting HDR set HDR_CAPABILITY bit in LSPCON_CAPABILITIES to 1. This patch reads the same, detects the HDR capability and adds this to intel_lspcon struct. v2: Addressed Jani Nikula's review comment and fixed the HDR capability detection logic v3: Deferred HDR detection from lspcon_init (Ville) v4: Addressed Ville's minor review comments, added his RB.

2020-11-27drm/i915/display: Suppress "Combo PHY A HW state changed unexpectedly"Chris Wilson
We know a problem exists in the ifwi shipped with the early pre-production Tigerlake and DG1 prototypes, later revisions are fine. However, CI still relies on the earlier ifwi and we grow tired of the volume of warnings as we wait for replacements. Since the warning is a bug, we do not want to lose the warning in its entirety, so only suppress the warning for the platforms currently exhibiting the issue.

2020-11-26drm/i915/display: Defer initial modeset until after GGTT is initialisedChris Wilson
Prior to sanitizing the GGTT, the only operations allowed in intel_display_init_nogem() are those to reserve the preallocated (and active) regions in the GGTT leftover from the BIOS. Trying to allocate a GGTT vma (such as intel_pin_and_fence_fb_obj during the initial modeset) may then conflict with other preallocated regions that have not yet been protected. Move the initial modesetting from the end of init_nogem to the beginning of init so that any vma pinning (either framebuffers or DSB, for example), is after the GGTT is ready to handle it. This will prevent the DSB object from being destroyed too early: [ 53.449241] BUG: KASAN: use-after-free in i915_init_ggtt+0x324/0x9e0 [i915] [ 53.449309] Read of size 8 at addr ffff88811b1e8070 by

2020-11-20drm: Pass the full state to connectors atomic functionsMaxime Ripard
The current atomic helpers have either their object state being passed as an argument or the full atomic state.

2020-11-20drm/i915/dg1: Enable portsAditya Swarup
For DG1 we have a little of mix up wrt to DDI/port names and indexes. Bspec refers to the ports as DDIA, DDIB, DDI USBC1 and DDI USBC2 (besides the DDIA, DDIB, DDIC, DDID), but the previous naming is the most unambiguous one. This means that for any register on Display Engine we should use the index of A, B, D and E. However in some places this is not true: - VBT: uses C and D and have to be mapped to D/E - IO/Combo: uses C and D, but we already differentiate those when we created the phy vs port distinction. This additional mapping for VBT and phy are already covered in previous patches, so now we can initialize all the DDIs as A, B, D and E. v2: Squash previous patch enabling just ports A and B since most of the pumbling code is already merged now Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Clinton Taylor <Clinton.A.Taylor@intel.com> Signed-off-by: Aditya Swarup <aditya.swarup@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201117084836.2318234-1-lucas.demarchi@intel.com

2020-11-19drm/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.

2020-11-17drm/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().

2020-11-16drm/i915: Store plane relative data rate in crtc_stateVille Syrjälä
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". And since the watermarks are computed based on the actual data rate anyway I don't really see what the point of this relative data rate is. But that's for the future...

2020-11-16drm/i915: Precompute can_sagv for each wm levelVille Syrjälä
In order to remove intel_atomic_crtc_state_for_each_plane_state() from skl_crtc_can_enable_sagv() we can simply precompute whether each wm level can tolerate the SAGV block time latency or not. This has the nice side benefit that we remove the duplicated wm level latency calculation. In fact the copy of that code we had in skl_crtc_can_enable_sagv() didn't even handle WaIncreaseLatencyIPCEnabled/Display WA #1141 whereas the copy in skl_compute_plane_wm() did. So now we just have the one copy which handles all the w/as.

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.
