Subject: [PATCH 15/22] dmx3191d: Drop max_sectors limit
Date: Mon, 14 Mar 2016 15:27:15 +1100 [thread overview]
Message-ID: <20160314042704.546012961@telegraphics.com.au> (raw)
In-Reply-To: 20160314042700.596192247@telegraphics.com.au
[-- Attachment #1: dmx3191d-max_sectors --]
[-- Type: text/plain, Size: 803 bytes --]
The dmx3191d driver is not capable of DMA or PDMA so all transfers
use PIO. Now that large slow PIO transfers periodically stop and call
cond_resched(), the max_sectors limit can go away.
