Just provide precomputed CSC matrices for the identity and limited range cases. This removes the remaining nuts and bolts stuff from ilk_load_csc_matrix(), allowing one to actually see the high level logic. Signed-off-by:

We have far too much messy duplicated code in the pipe/output CSC programming. Simply provide two functions (ilk_update_pipe_csc() and icl_update_output_csc()) to program the relevant CSC registers. The desired offsets and coefficients are passed in as parameters. Signed-off-by:

Like was done for MG and combo, now finish the per-type split of the vfunc by moving TBT out of the combo functions. Now we can completely remove icl_pll_id_to_enable_reg() since each PLL type passes all the information via arguments. Signed-off-by:

Create separate functions to 1) enable power, 2) write pll config, and 3) enable pll. Doing this it makes it easier to share the functions for the different PLL types by passing the right arguments. Signed-off-by:

Let's start using the vfuncs to differentiate MG and Combo PLLs. The end goal is to decouple the type of the PLL from the IDs since the latter are likely to change from one platform to another. This also makes the code easier to read by not having lots of if/else chains on leaf functions. Signed-off-by:

Large ppGTT are differentiated by the requirement to go to four levels to address more than 32b.

When any other value than EDP_PSR_TP4_TIME_0US is set, TPS1 and TPS4 will be used to do the link training when exiting PSR1. Happily the eDP panels tested so far was able to sync with source even without HBR3/TPS4 support but let use the right training pattern. TPS4 support was added to PSR1 registers because HBR3/PSR specification was not closed when ICL was freezed so if HBR3 was supported by PSR, ICL would already be ready but it was not added to specification so lets always disable TPS4. v3: Missed ";" SPANK SPANK SPANK!!!

In order to make it easier to bring up new platforms without having to take care about all corner cases that was previously taken care for previous platforms we already use comparative INTEL_GEN statements. Let's start doing the same with PCH. The only caveats are: - less-than comparisons need to be avoided or done with attention and check > PCH_NONE as well. - It is not necessarily a chronological order, but a matter of south display compatibility/inheritance. v2: Rebased on top of Jani's clean-up which removed the need for less-than comparison Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: -

This exactly same approach was already used from gen9 to gen10 and from gen10 to gen11. Let's also use it for gen11+. Let's first assume that we inherit a similar platform and than we apply the differences on top. Different from the previous attempts this will be done this time with coccinelle. We obviously need to exclude some case that is really exclusive for gen11 like PCH, Firmware, and few others. Luckly this was easy to filter by selecting the files we are touching with coccinelle as exposed below: spatch -sp_file gen11\+.cocci --in-place i915_perf.c \ intel_bios.c intel_cdclk.c intel_ddi.c \ intel_device_info.c intel_display.c intel_dpll_mgr.c \ intel_dsi_vbt.c intel_hdmi.c intel_mocs.c intel_color.c @noticelake@ expression e; @@ -!IS_ICELAKE(e) +INTEL_GEN(e) < 11 @notgen11@ expression e; @@ -!IS_GEN(e, 11) +INTEL_GEN(e) < 11 @icelake@ expression e; @@ -IS_ICELAKE(e) +INTEL_GEN(e) >= 11 @gen11@ expression e; @@ -IS_GEN(e, 11) +INTEL_GEN(e) >= 11 No functional change. v2: Remove intel_lrc.c per Tvrtko request since those were w/a for ICL hw issuea and media related configuration.

As this state may be in use by the GPU and we haven't been explicitly tracking its activity, we instead attach it to a request we send down the context setup with its new state and on retiring that request cleanup the old state as we then know that it is no longer live.

It is debatable whether having an error message on suspend for forcibly cancelling outstanding work is worthwhile. We want to know if it occurs in the wild (as we will then have to reconsider the approach!), but equally is not fatal across suspend, as upon resume we automatically clear the wedged status. However, CI does trigger this scenario with gem_eio/suspend; as there we are intentionally wedging the device upon suspend. The dilemma is how not to trigger a failure report for the dmesg spam, for which the quickest response is to suppress the warning in the kernel. I'd rather mark it as accepted in gem_eio, but for now detecting when gem_eio is playing games and cancelling the warning for that case seems a barely acceptable hack.

If PSR1 is active when pipe CRC is enabled the CRC calculations will be inhibit by the transition to low power states that PSR1 brings. So lets force a PSR1 exit and as soon as pipe CRC is enabled it will block PSR1 activation and avoid CRC timeouts when running IGT tests. There is a little window between the call to force exit PSR and the write to pipe CRC registers that needs to happen within the minimum of 6 idles frames otherwise PSR1 will be active again causing the CRC timeouts but anyways this will at least reduce the occurrence of CRC timeouts.
