X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=61067a5e69f548f5cb7f575f8e147956b60b2876;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Update legacy primary state outside the commit hook, v2. This should allow not running plane commit when the crtc is off. While the atomic helpers update those, crtc->x/y is only updated during modesets, and primary plane is updated after this function returns. Unfortunately non-atomic watermarks and fbc still depend on this state inside i915, so it has to be kept in sync. Changes since v1: - Add comment that the legacy state is updated for fbc.
