Aside from a few minor register changes and some different clock values, cdclk design hasn't changed much since gen9lp. Let's consolidate the handlers for bxt, cnl, and icl to keep the codeflow consistent. Also, while we're at it, s/bxt_de_pll_update/bxt_de_pll_readout/ since "update" makes me think we should be writing to hardware rather than reading from it. v2: - Fix icl_calc_voltage_level() limits. (Ville) - Use CNL_CDCLK_PLL_RATIO_MASK rather than BXT_DE_PLL_RATIO_MASK on gen10+ to avoid confusion. (Ville) v3: - Also fix ehl_calc_voltage_level() limits.

Empirical evidence from CI tells us that our rc6 setup for Tigerlake is off. Disable rc6 on tgl temporary so that we gain CI coverage as we prepare a fix. It also appears that the BIOS on our tgl leaves rc6 enabled, so we have to explicitly disable it on init. References: https://bugs.freedesktop.org/show_bug.cgi?id=111593Signed-off-by:

Currently, if there is time remaining before the start of the loop, we do one full iteration over many possible different chunks within the object. A full loop may take 50+s (depending on speed of indirect GTT mmapings) and we try separately with LINEAR, X and Y -- at which point igt times out. If we check more frequently, we will interrupt the loop upon our timeout -- it is hard to argue for as this significantly reduces the test coverage as we dramatically reduce the runtime. In practical terms, the coverage we should prioritise is in using different fence setups, forcing verification of the tile row computations over the current preference of checking extracting chunks. Though the exhaustive search is great given an infinite timeout, to improve our current coverage, we also add a randomised smoketest of partial mmaps. So let's do both, add a randomised smoketest of partial tiling chunks and the exhaustive (though time limited) search for failures. Even in adding another subtest, we should shave 100s off BAT! (With, hopefully, no loss in coverage, at least over multiple runs.) Signed-off-by:

Be paranoid and make sure we flush any and all writes out of the WCB before performing the UC mmio to update the RING_TAIL. (An UC write should itself be enough to do the flush, hence the paranoia here.) Quite infrequently, we see problems where the GPU seems to overshoot the RING_TAIL and so executes garbage, hence the speculation.

During reset, we try to ensure no forward progress of the CS prior to the reset by setting the STOP_RING bit in RING_MI_MODE. Since gen9, this register is context saved and do we end up in the odd situation where we save the STOP_RING bit and so try to stop the engine again immediately upon resume. This is quite unexpected and causes us to complain about an early CS completion event! Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111514Signed-off-by:

As we may unwind incomplete requests (for preemption) prior to processing the CSB and the schedule-out events, we may update rq->engine (resetting it to point back to the parent virtual engine) prior to calling execlists_schedule_out(), invalidating the assertion that the request still points to the inflight engine. (The likelihood of this is increased if the CSB interrupt processing is pushed to the ksoftirqd for being too slow and direct submission overtakes it.) Tvrtko summarised it as: "So unwind from direct submission resets rq->engine and races with process_csb from the tasklet which notices request has actually completed." Reported-by:

Gen 12 onwards moves the DP_TP_* registers to be transcoder-based rather than port-based. This adds the new register addresses and changes all the callers to use the register saved in intel_dp->regs.*. This is filled out when preparing to enable the port so we take into account if we should use the transcoder or the port. v2: reimplement by stashing the registers we want to access under intel_dp->reg. Now they are initialized when enabling the port. Ville suggested to store the transcoder to be used exclusively by TGL+.

It was enabling and checking PSR interruptions in every transcoder while it should keep the interruptions on the non-used transcoders masked. While doing this it gives us trouble on Tiger Lake if we are reading/writing to registers of disabled transcoders since from gen12 onwards the registers are relative to the transcoder. Instead of forcing them ON to access those registers, just avoid the accesses as they are not needed. v2 (Lucas): - Explain why we can't keep accessing all transcoders - Remove TODO about extending the irq handling to multiple instances: when/if implementing multiple instances it's pretty clear by the singleton psr that it needs to be extended - Fix intel_psr_debug_set() calling psr_irq_control() with psr.transcoder not set yet (from Imre). Now we only set the debug register right away if psr is already enabled. Otherwise we just record the value to be set when enabling the source. - Do not depend on the value of TRANSCODER_A. Just be relative to it (from Imre) - handle psr error last so we don't schedule the work before handling the other flags v3: - Adding a warning about setting reserverd bits on EDP_PSR_IMR Cc: Imre Deak <imre.deak@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Signed-off-by:

The cpu (de)tiler hw is gone, this stopped being useful. Plus it never supported any of the fancy new tiling formats, which means userspace also stopped using the magic side-channel this provides. This would totally break a lot of the igts, but they're already broken for the same reasons as userspace on gen12 would be. v2: Look at ggtt->num_fences instead, that also avoids the need for a comment (Chris). This also means that gen12 support really needs to make sure num_fences is set to 0. There is a patch for that, but it checks for HAS_MAPPABLE_APERTURE, which I'm not sure is the right thing really.

This reverts commit 4eaceea3. Several userspace clients (modesetting ddx and mutter+wayland at least) handle encoder.possible_crtcs incorrectly. What they essentially do is the following: possible_crtcs = ~0; for_each_possible_encoder(connector) possible_crtcs &= encoder->possible_crtcs; Ie. they calculate the intersection of the possible_crtcs for the connector when they really should be calculating the union instead. In our case each MST encoder now has just one unique bit set, and so the intersection is always zero. The end result is that MST connectors can't be lit up because no crtc can be found to drive them. I've submitted a fix for the modesetting ddx [1], and complained on #wayland about mutter, so hopefully the situation will improve in the future. In the meantime we have regression, and so must go back to the old way of misconfiguring possible_crtcs in the kernel.

This bit was fliped on for "syncing dependencies between camera and graphics". BSpec has no recollection why, and it is causing unrecoverable GPU hangs with Vulkan compute workloads. From BSpec, setting bit5 to 0 enables relaxed padding requirements for buffers, 1D and 2D non-array, non-MSAA, non-mip-mapped linear surfaces; and *must* be set to 0h on skl+ to ensure "Out of Bounds" case is suppressed.

For the legacy(gen < 4) gamma, add hw read out to create hw blob of gamma lut values. Also, add function intel_color_lut_pack to convert hw value with given bit precision to lut property val. v4: -No need to initialize *blob [Jani] -Removed right shifts [Jani] -Dropped dev local var [Jani] v5: -Returned blob instead of assigning it internally within the function [Ville] -Renamed function i9xx_get_color_config() to i9xx_read_luts() -Renamed i9xx_get_config_internal() to i9xx_read_lut_8() [Ville] v9: -Change in commit message [Jani, Uma] -Wrap commit within 75 characters [Uma] -Use macro for 256 [Uma] -Made read func para as const [Ville, Uma] v10: -Made i9xx_read_luts() static [Jani] Signed-off-by: -

Add macro to compare hw/sw gamma lut values. First need to check whether hw/sw gamma mode matches or not. If not no need to compare lut values, if matches then only compare lut entries. v5: -Called PIPE_CONF_CHECK_COLOR_LUT inside if (!adjust) [Jani] -Added #undef PIPE_CONF_CHECK_COLOR_LUT [Jani] v8: -Added check for gamma mode before gamma lut entry comparison [Jani] -Split patch 3 into 4 patches Signed-off-by:Uma Shankar <uma.shankar@intel.com> Reviewed-by:

Add func intel_color_lut_equal() to compare hw/sw gamma lut values. Since hw/sw gamma lut sizes and lut entries comparison will be different for different gamma modes, add gamma mode dependent checks. v3: -Rebase v4: -Renamed intel_compare_color_lut() to intel_color_lut_equal() [Jani] -Added the default label above the correct label [Jani] -Corrected smatch warn "variable dereferenced before check" [Dan Carpenter] v5: -Added condition (!blob1 && !blob2) return true [Jani] v6: -Made patch11 as patch3 [Jani] v8: -Split patch 3 into 4 patches -Optimized blob check condition [Ville] v9: -Exclude spilt gamma mode (bdw and ivb platforms) as there is exception in way gamma values are written in hardware [Ville] -Added exception made in commit [Uma] -Dropped else, character limit and indentation [Uma] -Added multi segmented gama mode for icl+ platforms [Uma] v10: -Dropped multi segmented mode for icl+ platforms [Jani] -Removed references of sw and hw state in compare code [Jani] -Dropped inline from func [Jani] Signed-off-by: -

Each platform supports different gamma modes and each gamma mode has different bit precision. Here bit precision corresponds to number of bits the hw LUT supports. Add func per platform to return bit precision corresponding to gamma mode which will be later used as a parameter in lut comparison function intel_color_lut_equal(). This is done for legacy, ilk, glk and their variant platforms. v6: -Added func intel_color_get_bit_precision() to get bit precision for gamma and degamma lut readout depending upon platform and corresponding to load_luts() [Ankit] -Made patch11 as patch3 [Jani] v7: -Renamed func intel_color_get_bit_precision() to intel_color_get_gamma_bit_precision() -Added separate function/platform for gamma bit precision [Ville] -Corrected checkpatch warnings v8: -Split patch 3 into 4 separate patches v9: -Changed commit message, gave more info [Uma] -Added precision func for icl+ platform v10: -Removed precision func for chv and icl+ platforms [Jani] -Added gamma_enable check once [Jani] Signed-off-by:
