Subject: dma-debug: check_for_stack background?
Date: Sun, 14 Jun 2009 20:56:29 +0200 [thread overview]
Message-ID: <4A3547DD.2010809@s5r6.in-berlin.de> (raw)
Hi,
it took a while but I finally noticed that the DMA debug facility warns
about mappings of on-stack memory. What's the problem with that? Are
there architectures which don't support such mappings, or is it a
question of caution not to DMA-map the stack?
