Subject: [PATCH 42/74] drm/amd/display: [FW Promotion] Release 0.1.83.0
Date: Wed, 11 Nov 2026 09:28:48 +0800	[thread overview]
Message-ID: <20261111014100.3596072-43-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20261111014100.3596072-1-Wayne.Lin@amd.com>

From: Taimur Hassan <Syed.Hassan@amd.com>

Updated DMUB interface
- Extend the SoC bounding box with urgent bandwidth targets, pipe and
  output counts, return-buffer sizes, and FAMS2 delay and timeout values
- Add RAMLESS_LOBF commands to copy static settings and to enable,
  disable, or wake the feature
- Carry a seamless-boot eDP request in the DCN init command
