[PATCH 0/4] dma-debug: driver filter

From: Joerg Roedel
Date: Thu May 28 2009 - 11:20:52 EST


this small patchset adds a new feature to dma-api debugging: a driver
filter. A driver developer can write the name of his driver to
dma-api/driver_filter and the kernel will then only print errors
produced by this driver. This is useful if other drivers in the system
also have bugs. In this case the driver developer can limit the bug
output to messages interesting for him.
