Add generic __to_intel_display() macro that accepts either struct drm_i915_private * or struct intel_display *.

2024-04-18drm/i915/display: add generic to_intel_display() macroJani Nikula
Convert various pointers to struct intel_display * using _Generic(). Add some macro magic to make adding new conversions easier, and somewhat abstract the need to cast each generic association. The cast is required because all associations needs to compile, regardless of the type and the generic selection. The use of *p in the generic selection assignment expression removes the need to add separate associations for const pointers. Note: This intentionally does *not* cover struct drm_i915_private or struct xe_device. They are not to be used in the long run, so avoid using this macro for them.

2024-04-17drm/i915: Unionize dpll_hw_stateVille Syrjälä
intel_dpll_hw_state contains space for all possible PLL register values across all platforms. That is rather wasteful as each machine only needs to store the registers values that are appropriate for the platform.

2024-04-17drm/i915: Carve up struct intel_dpll_hw_stateVille Syrjälä
struct intel_dpll_hw_state has a spot for all possible PLL registers across all platforms (well, apart from cx0/snps). This makes it rather confusing when trying to figure out which members belong to which platform(s). Split the struct up into five different platform specific sub-structures. For now this will actually increase the size a little bit as we have to duplicate a few members from skl to icl, but that will be remedied soon when we turn the thing into a union.

In order to reduce the DC5->DC2 restore time, wakelocks have been introduced in DMC so the driver can tell it when registers and other memory areas are going to be accessed and keep their respective blocks awake. Implement this in the driver by adding the concept of DMC wakelocks. When the driver needs to access memory which lies inside pre-defined ranges, it will tell DMC to set the wakelock, access the memory, then wait for a while and clear the wakelock. The wakelock state is protected in the driver with spinlocks to prevent concurrency issues.

2024-04-10drm/i915/mtl: Add DP FEC BS jitter WAImre Deak

2024-04-10drm/i915/mtl+: Disable DP/DSC SF insertion at EOL WAImre Deak
Disable the workaround inserting an SF symbol between the last DSC EOC symbol and the subsequent BS symbol. The WA is enabled by default - based on the register's reset value - and Bspec requires disabling it explicitly. Bspec doesn't provide an actual WA ID for this.

Add a workaround to fix timing issues on links with DSC enabled - presumedly related to the audio functionality. Bspec requires enabling this workaround if audio is enabled on ADLP, however Windows enables it whenever DSC is enabled ADLP onwards; follow Windows.

Add a workaround to fix BS jitter issues on MST links if the HBLANK period is less than 1 MTP. The WA applies only to UHBR rates while on non-UHBR the specification requires disabling it explicitly - presumedly because the register's reset value has the WA enabled.

Add a workaround to fix BS (blank start) to BS jitter issues on MST links when FEC is enabled. Neither Bspec requires this nor Windows clears the WA when disabling the output - presumedly because CHICKEN_MISC_3 gets reset after disabling the pipe/transcoder - so follow suit.

2024-04-09drm/i915: use check_add_overflow() and drop local variantsJani Nikula
Prefer common check_add_overflow() from overflow.h over the locally rolled versions of it. While check_add_overflow() does require a variable to assign to, unlike add_overflows_t(), it's still better than having multiple versions around.
