Subject: [PATCH v13 net-next 9/9] octeontx2-af: npc: cn20k: Allocate npc_priv and dstats dynamically.
Date: Mon, 11 May 2026 09:09:23 +0530	[thread overview]
Message-ID: <20260511033923.1301976-10-rkannoth@marvell.com> (raw)
In-Reply-To: <20260511033923.1301976-1-rkannoth@marvell.com>

Replace the file-scope static npc_priv with a kcalloc'd struct filled
from hardware bank/subbank geometry at init (num_banks is no longer a
const compile-time constant; drop init_done and use a non-NULL
npc_priv pointer for liveness). Thread npc_priv_get() / pointer access
through the CN20K NPC code paths, extend teardown to kfree the root
struct on failure and in npc_cn20k_deinit, and adjust MCAM section
setup to use the discovered subbank count.

Allocate MCAM debugfs dstats via devm_kzalloc instead of a static matrix,
and use the allocated backing store consistently when computing deltas
(including the counter rollover compare).
