From f1d25e0a9b1a6519580ddf5a7e5538093a504fcd Mon Sep 17 00:00:00 2001 From: Lior Amsalem Date: Tue, 26 May 2015 15:07:35 +0200 Subject: [PATCH] dmaengine: mv_xor: Enlarge descriptor pool size Now that we have 2 channels assigned to 2 CPUs and all requests are chained on same channels, we need much more descriptors available to satisfy async_tx workload. 3072 descriptors was found in our lab as the number of descriptors which allow the async_tx stack to work without waiting for free descriptors on submission of new requests.
