After switching to directly using dma_fence instead of i915_sw_fence we have left some dead code around intel_atomic_helper->free_list. Remove that dead code. v2: Remove intel_atomic_state->freed as well Signed-off-by:

Unlike later platforms TGL/ADLS has the half refresh rate (HRR) event on the main DMC (as opposed to the pipe DMC). Since we're disabling that event on all later platforms already let's do the same on TGL/ADLS as well. There is supposedly a bit somewhere (DMC_CHICKEN on TGL) to make the handler not do anything, but we don't currently have code to frob it. Though that bit should be off by default, the ADL+ experience has shown us that trusting any of this isn't a good idea. So seems safer to just disable all event handlers we know that we don't need. Also the TGL/ADLS DMC firmware is apparently using the wrong event (undelayed vblank) here anyway. It should be using the delayed vblank event instead (like ADL+ firmware does), but they didn't release a firmware fix for this and instead just hacked around this in the Windows driver code :/ v2: Also disable the event on ADLS (Imre) Cc: Imre Deak <imre.deak@intel.com> Signed-off-by:

Unlike later platforms TGL has its flip queue event (CLK_MSEC) on the main DMC (as opposed to the pipe DMC). Currently we're doing a second pass to disable that, but let's just follow the same approach as the later platforms and never even enable the event in the first place. Signed-off-by:

The pipe DMC seems to be making a mess of things in ADL. Various weird symptoms have been observed such as missing vblank irqs, typicalle happening when using multiple displays. Keep all pipe DMC event handlers disabled until needed (which is never atm). This is also what Windows does on ADL+. We can also drop DG2 from disable_all_flip_queue_events() since on DG2 the pipe DMC is the one that handles the flip queue events.

The cdclk->voltage_level if ladders are hard to read, especially as they're written the other way around compared to how bspec lists the limits. Let's rewrite them to use simple arrays that gives us the max cdclk for each voltage level. v2: Bump the jsl/ehl max cdclk in the table to 652.8 MHz to accommodate JSL machines in CI that boot with high cdclk Reviewed-by: -

Currently we have a hardcoded assumption that the cdclk divider (2*cd2x divider) is always 2 when squashing is used. While that is true for all current platforms it might not hold in the future. So eliminate the assumption and calculate the correct divider from the other parameters. v2: s/cd2x divider/cdclk divider/ (Gustavo) s/clock/unsquashed_cdclk/ (Gustavo) Reviewed-by: -

Currently we get bigjoiner config after the dsc get config, during HW readout. Since dsc_get_config now uses bigjoiner flags/pipes to compute DSC PPS parameter pic_width, this results in a state mismatch when Bigjoiner and DSC are used together. So call get bigjoiner config before calling dsc get config function.

The eDP 1.5 spec adds a clarification for eDP 1.4x: > For eDP v1.4x, if the Source device chooses the Main-Link rate by way > of DPCD 00100h, the Sink device shall ignore DPCD 00115h[2:0]. We write 0 to DP_LINK_BW_SET (DPCD 100h) even when using DP_LINK_RATE_SET (DPCD 114h). Stop doing that, as it can cause the panel to ignore the rate set method. Moreover, 0 is a reserved value for DP_LINK_BW_SET, and should not be used. v2: Improve the comments (Ville) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9081Tested-by:

Assuming crtc->state is pointing at the correct thing for the async flip commit is nonsense. If we had already queued up multiple commits this would point at the very lates crtc state even if the older commits hadn't even happened yet. Instead properly stage/arm the event like we do for async flips. Since we don't need to arm multiple of these at the same time we don't need a list like the normal vblank even processing uses.

In C20 pll_state link_bit_rate and clock fields are bit redundant. Since many of the helpers assume the clock values, which are different from link_bit_rate for dp2.0, convert the helpers to use the numbers that are compatible with link_bit_rate. Currently link_bit_rate is compatible with crtc_state->port_clock. The function intel_c20pll_calc_port_clock returns the number which is compatible with crtc_state->port_clock. In order to avoid extra conversions b/ween clock and link_bit_rate, remove "clock" field from the C20 pll_state and then rename "link_bit_rate" as "clock". While at it rely on crtc_state->port_clock during C20 Pll programming. Cc: Clint Taylor <clinton.a.taylor@intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Signed-off-by:

Since the plane_state variable is declared outside the scaler_users loop in intel_atomic_setup_scalers(), and it's never reset back to NULL inside the loop we may end up calling intel_atomic_setup_scaler() with a non-NULL plane state for the pipe scaling case. That is bad because intel_atomic_setup_scaler() determines whether we are doing plane scaling or pipe scaling based on plane_state!=NULL. The end result is that we may miscalculate the scaler mode for pipe scaling. The hardware becomes somewhat upset if we end up in this situation when scanning out a planar format on a SDR plane. We end up programming the pipe scaler into planar mode as well, and the result is a screenfull of garbage. Fix the situation by making sure we pass the correct plane_state==NULL when calculating the scaler mode for pipe scaling. Cc: stable@vger.kernel.org Signed-off-by:

On ADL+ the hardware automagically calculates the CCS AUX surface stride from the main surface stride, so when remapping we can't really play a lot of tricks with the main surface stride, or else the AUX surface stride would get miscalculated and no longer match the actual data layout in memory. Supposedly we could remap in 256 main surface tile units (AUX page(4096)/cachline(64)*4(4x1 main surface tiles per AUX cacheline)=256 main surface tiles), but the extra complexity is probably not worth the hassle. So let's just make sure our mapping stride is calculated from the full framebuffer stride (instead of the framebuffer width). This way the stride we program into PLANE_STRIDE will be the original framebuffer stride, and thus there will be no change to the AUX stride/layout.

The uncore code may not always be available (e.g. when we build the display code with Xe), so we can't always rely on having the uncore's spinlock. To handle this, split the spin_lock/unlock_irqsave/restore() into spin_lock/unlock() followed by a call to local_irq_save/restore() and create wrapper functions for locking and unlocking the uncore's spinlock. In these functions, we have a condition check and only actually try to lock/unlock the spinlock when I915 is defined, and thus uncore is available. This keeps the ifdefs contained in these new functions and all such logic inside the display code.
