Message-ID: <CO6PR18MB44844F47958867B2D29E930AD81A9@CO6PR18MB4484.namprd18.prod.outlook.com> (raw)
In-Reply-To: <20210701071807.2018505-1-michaelba@nvidia.com>
> The issue can cause illegal physical address access while a huge-page A

> The old MR can be matched using the virtual address of huge-page B but
> the HW will access the physical address of huge-page A which is no more
> part of the DPDK process.

> Register a driver callback for memory event in order to free out all the
> MRs of memory that is going to be freed from the dpdk process.
