Subject: [dpdk-dev] [PATCH v4 07/11] mempool/cnxk: add cn10k mempool ops
Date: Thu, 8 Apr 2021 15:20:45 +0530
Message-ID: <20210408095049.3100322-8-asekhar@marvell.com> (raw)
In-Reply-To: <20210408095049.3100322-1-asekhar@marvell.com>

Add Marvell CN10k mempool ops and implement CN10k mempool alloc.

CN10k has 64 bytes L1D cache line size. Hence the CN10k mempool
alloc does not make the element size an odd multiple L1D cache
line size as NPA requires the element sizes to be multiples of
128 bytes.
