2021-05-14drm/i915/xelpd: Increase maximum watermark lines to 255Matt Roper2-6/+12
XE_LPD continues to use the same "skylake-style" watermark programming as other recent platforms. The only change to the watermark calculations compared to Display12 is that XE_LPD now allows a maximum of 255 lines vs the old limit of 31. Due to the larger possible lines value, the corresponding bits representing the value in PLANE_WM are also extended, so make sure we read/write enough bits. Let's also take this opportunity to switch over to the REG_FIELD notation.

2021-05-14drm/i915/xelpd: Handle new location of outputs D and EMatt Roper5-22/+74
The DDI naming template for display version 12 went A-C, TC1-TC6. With XE_LPD, that naming scheme for DDI's has now changed to A-E, TC1-TC4. The XE_LPD design keeps the register offsets and bitfields relating to the TC outputs in the same location they were previously. The new "D" and "E" outputs now take the locations that were previously used by TC5 and TC6 outputs, or what we would have considered to be outputs "H" and "I" under the legacy lettering scheme. For the most part everything will just work as long as we initialize the output with the proper 'enum port' value. However we do need to take care to pick the correct AUX channel when parsing the VBT (e.g., a reference to 'AUX D' is actually asking us to use the 8th aux channel, not the fourth). We should also make sure that our encoders and aux channels are named appropriately so that it's easier to correlate driver debug messages with the bspec instructions. v2: - Update handling of TGL_TRANS_CLK_SEL_PORT.

This enables some HDMI 1.4 setups to support 4k60Hz output, which previously failed silently. AMDGPU had nearly the exact same issue. This problem description is therefore copied from my commit message of the AMDGPU patch. On some setups, while the monitor and the gpu support display modes with pixel clocks of up to 600MHz, the link encoder might not. This prevents YCbCr444 and RGB encoding for 4k60Hz, but YCbCr420 encoding might still be possible. However, which color mode is used is decided before the link encoder capabilities are checked. This patch fixes the problem by retrying to find a display mode with YCbCr420 enforced and using it, if it is valid.

2021-05-11drm/i915/display: Restructure output format computation for better expandabilityWerner Sembach1-31/+35
Couples the decission between RGB and YCbCr420 mode and the check if the port clock can archive the required frequency. Other checks and configuration steps that where previously done in between can also be done before or after. This allows for are cleaner implementation of retrying different color encodings. A slight change in behaviour occurs with this patch: If YCbCr420 is not allowed but display is YCbCr420 only it no longer fails, but just prints an error and tries to fallback on RGB.

2021-05-10drm/i915/display: remove strap checks from gen 9Lucas De Marchi1-25/+13
Direction on gen9+ was to stop reading the straps and only rely on the VBT for marking the port presence. This happened while dealing with WaIgnoreDDIAStrap and instead of using it as a WA, it should now be the normal flow. See commit 885d3e5b6f08 ("drm/i915/display: fix comment on skl straps"). For gen 10 it's hard to say if this will work or not since I can't test it, so leave it with the same behavior as before. For PCH_TGP we should still rely on the VBT to make ports E and F not available. v2 (Ville): - use display ver >= 9 to make it consistent with the rest of the driver instead of checking for == 9 - also handle CNL and only initialize port F if it is IS_CNL_WITH_PORT_F. Eventually CNL may be removed, but while it isn't let's keep it consistent everywhere Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Anusha Srivatsa <anusha.srivatsa@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210430223808.1078010-4-lucas.demarchi@intel.com

Since commit 45c0673aac97 ("drm/i915/bios: start using the intel_bios_encoder_data directly") we lookup the devdata for each port in intel_ddi_init() and just return if the port is not present in VBT (or if we didn't create a fake devdata for it if VBT is not available). So in intel_display.c we don't have to check intel_bios_is_port_present(), just rely on the check in intel_ddi_init(). v2: Rebase on commit 45c0673aac97 ("drm/i915/bios: start using the intel_bios_encoder_data directly") re-using that check in intel_ddi_init() instead of adding a new one.

2021-05-07drm/i915/adl_p: Add stride restriction when using DPTJosé Roberto de Souza1-0/+9
Alderlake-P have a new stride restriction when using DPT and it is used by non linear framebuffers. Stride needs to be a power of two to take full DPT rows, but stride is a parameter set by userspace. What we could do is use a fake stride when doing DPT allocation so HW requirements are met and userspace don't need to be changed to met this power of two restrictions but this change will take a while to be implemented so for now adding this restriction in driver to reject atomic commits that would cause visual corruptions.

2021-05-07drm/i915/xelpd: First stab at DPT supportVille Syrjälä9-26/+392
Add support for DPT (display page table). DPT is a slightly peculiar two level page table scheme used for tiled scanout buffers (linear uses direct ggtt mapping still). The plane surface address will point at a page in the DPT which holds the PTEs for 512 actual pages. Thus we require 1/512 of the ggttt address space compared to a direct ggtt mapping. We create a new DPT address space for each framebuffer and track two vmas (one for the DPT, another for the ggtt). TODO: - Is the i915_address_space approaach sane? - Maybe don't map the whole DPT to write the PTEs? - Deal with remapping/rotation? Need to create a separate DPT for each remapped/rotated plane I guess. Or else we'd need to make the per-fb DPT large enough to support potentially several remapped/rotated vmas.

2021-05-07drm/i915: Reorder skl+ scaler vs. plane updatesVille Syrjälä2-11/+30
When scanning out NV12 if we at any time have the plane enabled while the scaler is disabled we get a pretty catastrophic underrun. Let's reorder the operations so that we try to avoid that happening even if our vblank evade fails and the scaler enable/disable and the plane enable/disable get latched during two diffent frames. This takes care of the most common cases. I suppose there is still at least a theoretical possibility of hitting this if one plane takes the scaler away from another plane before the second plane had a chance to set up another scaler for its use. But that is starting to get a bit complicated, especially since the plane commit order already has to be carefully sequenced to avoid any dbuf overlaps. So plugging this 100% may prove somewhat hard...
