Subject: Re: [dpdk-dev] [PATCH v3 13/35] mempool: store physical address in objects
Date: Wed, 25 May 2016 17:51:35 +0000 [thread overview]
Message-ID: <A09C9DDE180C7E429EC68E2BFB95C90339397519@IRSMSX107.ger.corp.intel.com> (raw)

Hi,
While running the QAT PMD tests, a system hang is observed when this commit is used.
rte_mempool_virt2phy is used in qat_crypto.c.
regards,
Deepak

Subject: [dpdk-dev] [PATCH v3 13/35] mempool: store physical address in objects
Store the physical address of the object in its header. It simplifies
rte_mempool_virt2phy() and prepares the removing of the paddr[] table in the mempool header.
