Subject: [PATCH v11 02/18] drm/i915/dmc: Add pipe dmc registers and bits for DC Balance
Date: Tue, 23 Dec 2025 16:15:24 +0530 [thread overview]
Message-ID: <20251223104542.2688548-3-mitulkumar.ajitkumar.golani@intel.com> (raw)
In-Reply-To: <20251223104542.2688548-1-mitulkumar.ajitkumar.golani@intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Add pipe dmc registers and access bits for DC Balance params
configuration and enablement.
--v2:
- Separate register definitions for transcoder and
pipe dmc. (Ankit)
- Use MMIO pipe macros instead of transcoder ones. (Ankit)
- Remove dev_priv use. (Jani, Nikula)
--v3:
- Add all register address, from capital alphabet to small. (Ankit)
- Add EVT CTL registers.
- Add co-author tag.
- Add event flag for Triggering DC Balance.
--v4:
- Add DCB Flip count and balance reset registers.
--v5:
- Correct macro usage for flip count. (Ankit)
- Use register offset in lower case.
