Subject: [RFC][PATCH 0/3] fixes and MPC8308 support for the mpc512x_dma driver
Date: Tue, 28 Sep 2010 14:24:53 +0200 [thread overview]
Message-ID: <1285676696-5358-1-git-send-email-yanok@emcraft.com> (raw)
Hello everybody,
I've found that mpc512x_dma doesn't work reliable in my tests (dmatest
module and NetPipe with CONFIG_NET_DMA enabled).
These patches fixes two issues I've found: inproper handling of
scatter/gather transfers and missing interrupts.
The third patch adds support for MPC8308 which has pretty much the same
DMA controller as MPC5121.
The first patch has an issue: I'm accessing IO space with direct memory
access not via accessor functions. I don't know how to use accessor
functions with bitfield structures.
Any comments would be appreciated.
With these patches applied my tests succeed both on MPC5121 and MPC8308.
Regards, Ilya.
