* drm/i915/dp: Change a link bandwidth computation for DPGwan-gyeong Mun2019-05-231-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Data M/N calculations were assumed a bpp as RGB format. But when we are using YCbCr 4:2:0 output format on DP, we should change bpp calculations as YCbCr 4:2:0 format. The pipe_bpp value was assumed RGB format, therefore, it was multiplied with 3. But YCbCr 4:2:0 requires a multiplier value to 1.5. Therefore we need to divide pipe_bpp to 2 while DP output uses YCbCr4:2:0 format. - RGB format bpp = bpc x 3 - YCbCr 4:2:0 format bpp = bpc x 1.5 But Link M/N values are calculated and applied based on the Full Clock for YCbCr 4:2:0. And DP YCbCr 4:2:0 does not need to pixel clock double for a dotclock caluation. Only for HDMI YCbCr 4:2:0 needs to pixel clock double for a dot clock calculation. It only affects dp and edp port which use YCbCr 4:2:0 output format. And for now, it does not consider a use case of DSC + YCbCr 4:2:0. v2: Addressed review comments from Ville. Remove a changing of pipe_bpp on intel_ddi_set_pipe_settings(). Because the pipe is running at the full bpp, keep pipe_bpp as RGB even though YCbCr 4:2:0 output format is used. Add a link bandwidth computation for YCbCr4:2:0 output format. v3: Addressed reivew comments from Ville. In order to make codes simple, it adds and uses intel_dp_output_bpp() function. v6: Link M/N values are calculated and applied based on the Full Clock for YCbCr420. The Bit per Pixel needs to be adjusted for YUV420 mode as it requires only half of the RGB case. - Link M/N values are calculated and applied based on the Full Clock - Data M/N values needs to be calculated considering the data is half due to subsampling Remove a doubling of pixel clock on a dot clock calculator for DP YCbCr 4:2:0. Rebase and remove a duplicate setting of vsc_sdp.DB17. Add a setting of dynamic range bit to vsc_sdp.DB17. Change Content Type bit to "Graphics" from "Not defined". Change a dividing of pipe_bpp to muliplying to constant values on a switch-case statement. v7: Addressed review comments from Ville. Move a setting of dynamic range bit and a setting of bpc which is based on pipe_bpp to a "drm/i915/dp: Program VSC Header and DB for Pixel Encoding/Colorimetry Format" commit.

* drm/i915/dp: Add a config function for YCBCR420 outputsGwan-gyeong Mun2019-05-231-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch checks a support of YCBCR420 outputs on an encoder level. If the input mode is YCBCR420-only mode then it prepares DP as an YCBCR420 output, else it continues with RGB output mode. It set output_format to INTEL_OUTPUT_FORMAT_YCBCR420 in order to using a pipe scaler as RGB to YCbCr 4:4:4. v2: Addressed review comments from Ville. Style fixed with few naming. %s/config/crtc_state/ %s/intel_crtc/crtc/ If lscon is active, it makes not to call intel_dp_ycbcr420_config() to avoid to clobber of lspcon_ycbcr420_config() routine. And it move the 420_only check into the intel_dp_ycbcr420_config(). v3: Fix uninitialized return value and it is reported by Dan Carpenter. v4: Addressed review comments from Ville. In order to avoid the extra indentation, it inverts if-clause on intel_dp_ycbcr420_config(). Remove the error print where no errors print are allowed. v6: Rebase v7: Move intel_dp_get_colorimetry_status() to intel_dp from intel_psr. intel_dp_get_colorimetry_status() checks VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED bit in the DPRX_FEATURE_ENUMERATION_LIST register.

That may in theory be possible on TypeC legacy ports, but I'm not sure if that's a practical scenario, so let's deal with that only if there's a use case.

* drm/i915: Remove the unneeded AUX power ref from intel_dp_detect()Imre Deak2019-05-141-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't need the AUX power for the whole duration of the detect, only when we're doing AUX transfers. The AUX transfer function takes its own reference on the AUX power domain already. The two places during detect which access display core registers (not specific to a pipe/port/transcoder) only need the power domain that is required for that access. That power domain is equivalent to the device global power domain on most platforms (enabled whenever we hold a runtime PM reference) except on CHV/VLV where it's equivalent to the display power well. Add a new power domain that reflects the above, and use this at the two spots accessing registers. With that we can avoid taking the AUX reference for the whole duration of the detect function. Put the domains asynchronously to avoid the unneeded on-off-on toggling. Also adapt the idea from with_intel_runtime_pm et al. for making it easy to write short sequences where a display power ref is needed. v2: (Ville) - Add with_intel_display_power() helper to simplify things. - s/bool res/bool is_connected/ Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190509173446.31095-8-imre.deak@intel.com

* drm/i915: Lift acquiring the vlv punit magic to a common sb-getChris Wilson2019-04-261-2/+2
| | | | | | | | | | | | | | | As we now employ a very heavy pm_qos around the punit access, we want to minimise the number of synchronous requests by performing one for the whole punit sequence rather than around individual accesses. The sideband lock is used for this, so push the pm_qos into the sideband lock acquisition and release, moving it from the lowlevel punit rw routine to the callers. In the first step, we move the punit magic into the common sideband lock so that we can acquire a bunch of ports simultaneously, and if need be extend the workaround protection later.

| | | | | | | | | | | | | | | | | Currently we enable FEC even when DSC is no used. While that is theoretically valid supposedly there isn't much of a benefit from this. But more importantly we do not account for the FEC link bandwidth overhead (2.4%) in the non-DSC link bandwidth computations. So the code may think we have enough bandwidth when we in fact do not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bitfield.h defines FIELD_GET() and FIELD_PREP() macros to access bitfields using the mask alone, with no need for separate shift. Indeed, the shift is redundant. We define REG_FIELD_GET() and REG_FIELD_PREP() wrappers for the above, in part to force u32 and for consistency with REG_BIT() and REG_GENMASK(), but also as we'll need to redefine REG_FIELD_PREP() in follow-up work to make it produce integer constant expressions. For the most part, REG_FIELD_GET() is shorter than masking followed by shift, and arguably has more clarity. REG_FIELD_PREP() can get more verbose than simply shifting in place, but it does provide masking to ensure we don't overflow the mask, something we usually don't bother with currently. Convert power sequencer registers as an example. v3: - temp variable removal (Chris) - rebase v2: - Add the REG_FIELD_GET() and REG_FIELD_PREP() wrappers to use them consistently from the start.
