Subject: [PATCH v3 06/24] drm/xe/xe3p_lpm: Handle MCR steering
Date: Thu, 16 Oct 2025 19:26:25 -0700	[thread overview]
Message-ID: <20251016-xe3p-v3-6-3dd173a3097a@intel.com> (raw)
In-Reply-To: <20251016-xe3p-v3-0-3dd173a3097a@intel.com>

From: Matt Roper <matthew.d.roper@intel.com>

Xe3p_LPM's MCR steering has the same ranges and behavior as Xe3_LPM.
However one register range that was reserved on Xe3_LPM has now become a
unicast range (0x384200-0x38427F), so we need to stop consolidating the
adjacent MCR ranges into a single table entry in the table.  With this
change to the Xe3_LPM table, we can continue to use the same table for
both IP families.

While we're touching this table, take the opportunity to fix a
whitespace mistake and clarify that one of the other consolidated range
entries includes a reserved range.
