2014-01-20dma: pl330: Use dma_get_slave_channel() in the of xlate callbackLars-Peter Clausen1-27/+8
Currently the driver uses dma_request_channel() with a custom filter function to find the requested channel. This will loop over all available channels until the one we want has been found, but we already know which channel we want to request, so we can dma_get_slave_channel(). This also makes the code a bit shorter cleaner. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
2014-01-20dma: pl330: Differentiate between submitted and issued descriptorsLars-Peter Clausen1-4/+20
The pl330 dmaengine driver currently does not differentiate between submitted and issued descriptors. It won't start transferring a newly submitted descriptor until issue_pending() is called, but only if it is idle. If it is active and a new descriptor is submitted before it goes idle it will happily start the newly submitted descriptor once all earlier submitted descriptors have been completed. This is not a 100% correct with regards to the dmaengine interface semantics. A descriptor is not supposed to be started until the next issue_pending() call after the descriptor has been submitted. This patch adds a second per channel list that keeps track of the submitted descriptors. Once issue_pending() is called the submitted descriptors are moved to the working list and only descriptors on the working list are started.

2014-01-20DMA: Freescale: change BWC from 256 bytes to 1024 bytesHongbo Zhang1-1/+1
Freescale DMA has a feature of BandWidth Control (ab. BWC), which is currently 256 bytes and should be changed to 1024 bytes for best DMA throughput. Changing BWC from 256 to 1024 will improve DMA performance much, in cases whatever one channel is running or multi channels are running simultanously, large or small buffers are copied. And this change doesn't impact memory access performance remarkably, lmbench tests show that for some cases the memory performance are decreased very slightly, while the others are even better. Tested on T4240. Signed-off-by: Hongbo Zhang <hongbo.zhang@freescale.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

2014-01-13dma: imx-sdma: Assign a default script number for ROM firmware casesNicolin Chen1-0/+4
i.MX series have inner firmware in its ROM code: when SDMA isn't provided any firmware from Kernel or rootfs, the default inner ROM firmware will be activated. However the current driver doesn't assign any script number to this situation, and those platform running in this case would be broken. Thus this patch adds a default script number when no external firmware being loaded so that people would continue to be able to use basic scripts to run their platform without any firmware.

2014-01-13Revert "ARM: dts: imx: use dual-fifo sdma script for ssi"Nicolin Chen4-16/+16
This reverts commit b1d27c79c8377df1880447375deffa3bb82c7bd3. Previously we switched the SSI scriprt to dual-fifo mode to reduce playback underrun issue, which is only included by SDMA firmware version 2. However, there are quite a lot people still using version 1 or default firmware in the ROM code of SoC while these two kinds of firmwares do not support the dual-fifo script and the audio function on their platform would be broken. Thus this patch provisionally reverts the dual-fifo script to the original single fifo script to meet all kinds of users' requirements, including the version 1/2 or inner ROM firmware.

2013-12-15Revert "selinux: consider filesystem subtype in policies"Linus Torvalds2-60/+22
This reverts commit 102aefdda4d8275ce7d7100bc16c88c74272b260. Tom London reports that it causes sync() to hang on Fedora rawhide: https://bugzilla.redhat.com/show_bug.cgi?id=1033965 and Josh Boyer bisected it down to this commit. Reverting the commit in the rawhide kernel fixes the problem. Eric Paris root-caused it to incorrect subtype matching in that commit breaking fuse, and has a tentative patch, but by now we're better off retrying this in 3.14 rather than playing with it any more.

A fix for possible memory corruption during DM table load, fix a possible leak of snapshot space in case of a crash, fix a possible deadlock due to a shared workqueue in the delay target, fix to initialize read-only module parameters that are used to export metrics for dm stats and dm bufio. Quite a few stable fixes were identified for both the thin- provisioning and caching targets as a result of increased regression testing using the device-mapper-test-suite (dmts). The most notable of these are the reference counting fixes for the space map btree that is used by the dm-array interface -- without these the dm-cache metadata will leak, resulting in dm-cache devices running out of metadata blocks.
