Can you please add that > information to the commit text as well. I have only tested on AM180x with uio_pruss and davinci-pcm (series for that posted a short while ago). In the uio_pruss case, I run the sample applications from the userspace PRU package that test communication with the shared SRAM, DDR, and internal PRU SRAM. For davinci-pcm, my series enables shared SRAM ping-pong buffering which is working comparably to pcm capture/playback without ping-pong buffering enabled on AM180x. I have not tested PM at all...yet. I'll add this detail to the commit. -Matt -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
