Subject: [PATCH bpf-next 2/3] selftests: xsk: Use hugepages when umem->frame_size > PAGE_SIZE
Date: Sun, 19 Mar 2023 20:56:55 +0100 [thread overview]
Message-ID: <20230319195656.326701-3-kal.conley@dectris.com> (raw)
In-Reply-To: <20230319195656.326701-1-kal.conley@dectris.com>
HugeTLB UMEMs now support chunk_size > PAGE_SIZE. Set MAP_HUGETLB when
frame_size > PAGE_SIZE for future tests.
