Subject: dma/idxd: configure maximum batch size to high value
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;ds=sidebyside;h=6a87d036a7ced87ba39406032c42ec2749b2cb88;hp=6a87d036a7ced87ba39406032c42ec2749b2cb88;p=dpdk.git

dma/idxd: configure maximum batch size to high value

When configuring an Intel DSA instance using the utility script
dpdk_idxd_cfg.py, explicitly set the max supported batch size value to a
high value, to ensure large bursts are supported if so desired. The
default in the linux kernel is now just 32 [1], which may not be
sufficient for all DPDK apps.
