Subject: [PATCH 0/2] cnxk: Add HALO support for CN20K mempool
Date: Thu, 4 Dec 2025 12:21:31 +0530 [thread overview]
Message-ID: <20251204065203.1866809-1-nkishor@marvell.com> (raw)
This patch series introduces HALO support for the CN20K platform.
On earlier platforms (CN9K/CN10K), the NPA mempool required separate
aura and pool contexts even for a 1:1 aura-to-pool mapping. This led to
unnecessary context usage for the most common use case.
With CN20K, HALOs allow replacing this 1:1 aura/pool model with a single
combined context, reducing context consumption and simplifying mempool
management.
Patch 1 adds HALO creation support in the ROC common layer.
Patch 2 integrates HALO usage into the CN20K mempool driver and adds a
new "halo_ena" devarg to enable or disable this feature.
