Subject: [PATCH v2 01/18] common/cnxk: fix engine capabilities fetch logic
Date: Tue, 17 Feb 2026 11:09:26 +0530 [thread overview]
Message-ID: <20260217053943.2748100-1-rbhansali@marvell.com> (raw)
From: Rakesh Kudurumalla <rkudurumalla@marvell.com>
For CN9k platform, incorrect status is checked from LOAD
FVC instruction while retrieving engine capabilities.
The loop is updated for a valid return status check on
LOADFVC instruction.
Fixes: 7c67c489d466 ("common/cnxk: fetch engine capabilities")
