As the maximum addressable bits is determined by platform, record that information in our static chipset tables. This has the advantage of being clearly recorded in our capability dumps for dmesg, debugfs and error states. Based on a patch by Bob Paauwe. Signed-off-by:

I just noticed that initial PCH comparative patch left some >= PCH_ICP cases behind. Let's also cover these cases and leave only the pin map behind now. No functional change. Hence no fixes tag. Cc: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by:

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.

In the next patch, we will want to update live state within a context. 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. This can possibily fix issues present right now but I did not found any open, I mostly got this issue from previous CI runs of this series, bellow some exambles: * igt@kms_color@pipe-b-ctm-0-75: - shard-apl: PASS -> FAIL +9 * igt@kms_cursor_legacy@flip-vs-cursor-busy-crc-legacy: - shard-apl: PASS -> DMESG-FAIL +17 * igt@kms_frontbuffer_tracking@fbc-1p-primscrn-indfb-pgflip-blt: - shard-kbl: PASS -> DMESG-FAIL +12 * igt@kms_pipe_crc_basic@read-crc-pipe-c: - shard-kbl: PASS -> FAIL +7 v6: s/PSR/PSR1 (Dhinakaran) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

When PSR2 is active aka after the number of frames programmed in PSR2_CTL 'Frames Before SU Entry' hardware stops to generate CRC interrupts causing IGT tests to fail due timeout. This same behavior don't happen with PSR1, as soon as pipe CRC is enabled it blocks PSR1 activation so CRC calculation continues to happens normaly. This patch also set mode_changed as true when PSR is available to force atomic check functions to compute new PSR state, otherwise PSR2 would not be disabled. v4: Only setting mode_changed if has_psr is set(Dhinakaran) v3: Reusing intel_crtc_crc_prepare() and crc_enabled, only setting mode_changed if it can do PSR. v2: Changed commit description to describe that PSR2 inhibit CRC calculations.

In any commit, intel_modeset_pipe_config() will initialilly clear and then recalculate most of the pipe states but it leave intel specific color features states in reset state. If after intel_pipe_config_compare() is detected that a fastset is possible it will mark update_pipe as true and unsed mode_changed, causing the color features state to be kept in reset state and then latter being committed to hardware disabling the color features. This issue can be reproduced by any code patch that duplicates the actual(with color features already enabled) state and only mark mode_changed as true. Reviewed-by:

Forcing a specific CRTC to the eDP connector was causing the intel_psr_fastset_force() to mark mode_chaged in the wrong and disabled CRTC causing no update in the PSR state.

Introduce a mutex to start locking the HW contexts independently of struct_mutex, with a view to reducing the coarse struct_mutex. The intel_context.pin_mutex is used to guard the transition to and from being pinned on the gpu, and so is required before starting to build any request. The intel_context will then remain pinned until the request completes, but the mutex can be released immediately unpin completion of pinning the context. A slight variant of the above is used by per-context sseu that wants to inspect the pinned status of the context, and requires that it remains stable (either !pinned or pinned) across its operation. By using the pin_mutex to serialise operations while pin_count==0, we can take that pin_mutex for stabilise the boolean pin status. v2: for Tvrtko! * Improved commit message. * Dropped _gpu suffix from gen8_modify_rpcs_gpu. v3: Repair the locking for sseu selftests Signed-off-by:
