2025-06-26drm/i915/bw: make struct intel_bw_state opaqueJani Nikula
With all the code touching struct intel_bw_state moved inside intel_bw.c, we move the struct definition there too, and make the type opaque. to_intel_bw_state() needs to be turned into a proper function.

When KMSAN is enabled, this function causes has a rather excessive stack usage: drivers/gpu/drm/i915/display/skl_watermark.c:2977:1: error: stack frame size (1432) exceeds limit (1408) in 'skl_compute_wm' [-Werror,-Wframe-larger-than] This is apparently all caused by the varargs calls to drm_dbg_kms(). Inlining this into skl_compute_wm() means that any function called by skl_compute_wm() has its own stack on top of that.

2025-06-23drm/i915/pcode: drop fast wait from snb_pcode_write_timeout()Jani Nikula
Only use the ms granularity wait in snb_pcode_write_timeout(), primarily to better align with the xe driver, which also only has the millisecond wait. Use an arbitrary 250 us fast wait before the specified ms wait, and have snb_pcode_write() default to 1 ms. This means snb_pcode_write() and snb_pcode_write_timeout() will always be sleeping functions. There should not be any atomic users for pcode writes though, and any display code using pcode via xe has already been non-atomic. The uncore wait will do a might_sleep() annotation that should catch any problems.

2025-06-23drm/i915/dmc: Do not enable the pipe DMC on TGL when PSR is possibleVille Syrjälä
On TGL/derivatives the pipe DMC state is lost when PG1 is disabled, and the main DMC does not restore any of it. This means the state will also be lost during PSR+DC5/6. It seems safest to not even enable the pipe DMC in that case (the main DMC does restore the pipe DMC enable bit in PIPEDMC_CONTROL_A for some reason). Since pipe DMC is only needed for "fast LACE" on these platforms we aren't actually losing anything here. In the future if we do want to enable "fast LACE" we'll just have to remember that it won't be compatible with PSR.

2025-06-23drm/i915/dmc: Reload pipe DMC MMIO registers for pipe C/D on various platformsVille Syrjälä
On ADL/MTL pipe DMC MMIO state evidently lives in PG0. The main DMC saves/restores it for pipes A/B, but for pipes C/D we have to do it in the driver. On PTL the situation is mostly the same, except the main DMC firmware doesn't seem to have the PG0 save/restore code anymore, and instead the hardware (or maybe Punit?) seems to take care of this job now. Pipes C/D still need a manual restore by the driver. On LNL I've been unable to lose any pipe DMC state, despite the main DMC firmware still implementing the PG0 save/restore for pipes A/B. Not sure what's going on here. On DG2 I've also not been able to lose the pipe DMC state. DG2 doesn't support DC6, so that might explain part of it. But even DC9 doesn't make a difference here. Perhaps PG0 is just always on for DG2? BMG I've not tested at all. The main DMC firmware does appaer to implement the PG0 pipe A/B save/restore logic.

The other option would be to not load the pipe DMC at all since it's only needed for "fast LACE" (which we don't use) on these platforms.

The values of ana_cp_int, and ana_cp_prop are clamped between 1 and 127. Use the more intuitive and readable clamp() macro instead of using nested max(min(...)).

2025-06-19drm/i915/snps_hdmi_pll: Fix 64-bit divisor truncation by using div64_u64Ankit Nautiyal
DIV_ROUND_CLOSEST_ULL uses do_div(), which expects a 32-bit divisor. When passing a 64-bit constant like CURVE2_MULTIPLIER, the value is silently truncated to u32, potentially leading to incorrect results on large divisors. Replace DIV_ROUND_CLOSEST_ULL with DIV64_U64_ROUND_CLOSEST which correctly handles full 64-bit division. v2: Use DIV64_U64_ROUND_CLOSEST instead of div64_u64 macro.
