From: Ville Syrjälä <ville.syrj...@linux.intel.com> Here's an updated version of the series to redo the VLV/CHV watermark code. The most important thing is that this makes the display stable on BSW with the fancy new memory PM features enabled by the firmware.
Changes since v1: * Drop the two plane maxfifo mode patch (Vijay) * Move one the misplaced hunk to the right patch (Jesse) * Use the right amount of PFI credits for the cdclk<czclk case (Vijay) * Drop the extra drain latency multipler frobbing as it no longer seems to be necessary to get a stable picture with multiple 4k displays. Not really sure if this was due to a BIOS update or what. * Use plane->state->fb instead of plane->fb in the wm/ddl calculations. * Don't break VLV maxfifo enable/disable. Noticed this one myself while going through the patches I'm still missing a review on "drm/i915: Rewrite VLV/CHV watermark code" and "drm/i915: Disable DDR DVFS on CHV" The rest have r-bs now. I kept Jesses r-b on "drm/i915: Pass plane to vlv_compute_drain_latency()" even though v2 is a slightly different that v1 due to the plane->state changes.
