edram is not part of uncore and there is no requirement for the detection to be done before we initialize the uncore functions. The first check on HAS_EDRAM is in the ggtt_init path, so move it to i915_driver_init_hw, where other dram-related detection happens. While at it, save the size in MB instead of the capabilities because the size is the only thing we look at outside of the init function. Signed-off-by:

-
Ville Syrjälä authored
Unlike the earlier platforms GLK has dedicated degamma and gamma LUTs. And quite curiously the degamma LUT is actually controlled via the PLANE_COLOR_CTL CSC enable bit. Hence we must compute gamma_enable and csc_enable differently to pre-GLK platforms. Signed-off-by:

ICL is rather easy when it comes to .color_check() as it finally provides us with a full color pipeline with individual knobs for each stage. We'll also start bypassing each LUT individually when it is not needed. Signed-off-by:

Ville Syrjälä authored
Since CHV has the CGM unit we require a custom implementation of .color_check(). This fixes the computation of gamma_enable as previously we left it enabled even when were using the CGM gamma instead.

The current intel_color_check() is a mess, and worse yet it is in fact incorrect for several platforms. The hardware has evolved quite a bit over the years, so let's just go for a clean split between the platforms by turning this into a vfunc.

Maarten Lankhorst authored
Y41x formats is a 4:4:4 format, so it can be addressed with pixel level accuracy. Meanwhile it seems that while rotating YUYV 4:2:2 formats need a multiple of 2 for width and height, otherwise corruption occurs. For YUV 4:2:2, the spec says that w/h should always be even, but we get away with odd height while unrotated. When rotating it seems corruption occurs with an odd x/y, and w/h should always be even. Just to be completely paranoid, reject odd x/y w/h when rotating 90/270. Signed-off-by:

The intent was to expose these as part of the means to perform full context recovery (though not the SINGLE_TIMELINE, that is for later and just sucked as collateral damage). As that requires a couple more patches to complete the series, roll back the earlier chunks of ABI for an intervening PR. We keep all the internals intact and under selftests. Signed-off-by:

This is to disable semaphore usage when on vGPU for now. Unfortunately GVT-g hasn't fully enabled semaphore usage yet, so current guest with semaphore use would cause vGPU failure. Although current semaphore failure with vGPU can be simply resolved by allowing cmd parser to accept MI_SEMAPHORE_WAIT command with address audit, we're checking general usage of semaphore and how we should handle it properly for virtualization in consider of function and security concern. So we decide to request to disable it for now in guest driver. Once GVT could support it, we would add new compat bit to turn it on.

Update the DP MSA MISC bits for fastsets. This is needed when we change between limited and full range RGB output. On HSW+ changing limited_range does not currently result in a full modeset since we have don't have the readout code for it (for DP we could, and probably should, readout from TRANS_MSA_MISC itself, for HDMI we would have to rely on the infoframe). So the PIPE_CONF_CHECK() is only performed for pre-HSW platforms. That means any change in the value will result in a fastset instead. Fortunately there is no prohibition to changing TRANS_MSA_MISC dynamically, so it looks like we can legally do fastsets for this. Signed-off-by:
