mxc: gadget: Fix bitfield for calculating maximum packet size
Hello. Dinh.Nguyen(a)freescale.com wrote: From: Dinh Nguyen <Dinh.Nguyen(a)freescale.com> The max packet length bit mask used for isochronous endpoints should be 0x7FF instead of 0x8FF. 0x8FF will actually clear higher-order bits in the max packet length field.

[PATCH] DMA ENGINE: Do not reset 'private' of channel
The member 'private' of 'struct dma_chan' is meant for passing data between client and the controller driver. The DMA client driver may point it to platform specific stuff after acquiring the channel. So, it is the responsiblity of the same code to reset it, if it must. The DMA engine doesn't set it and hence,... 4 May 2010 05:43

significant variation in performance counters on POWER6
Hello, I am doing some research where I need to collect performance information for SPEC CPU2006 benchmarks on a POWER6 JS22 system. Previously I was using perfmon2, but after the release of "performance counters for linux" (and the 'perf' tool), I decided to try it. One of the reasons was the native support f... 4 May 2010 03:32
