Subject: [PATCH] x86: bump PREALLOC_DMA_DEBUG_ENTRIES
Date: Fri, 16 Nov 2012 11:17:14 +0100 [thread overview]
Message-ID: <50A612AA.7040206@canonical.com> (raw)
I ran out of free entries when I had CONFIG_DMA_API_DEBUG enabled.
Some other archs seem to default to 65536, so increase this limit for x86 too.
