2014-06-24 06:59 <apelete> good morning
2014-06-24 07:06 <apelete> larsc: deactivated the dma completion callback last night to see if dma transfer fares better
2014-06-24 07:06 <apelete> http://git.seketeli.net/cgit/~apelete/qi-kernel.git/commit/?h=jz4740-dma
2014-06-24 07:09 <apelete> did some boot time and zcat tests, results look much better -> http://paste.debian.net/106478/
2014-06-24 07:09 <apelete> 
2014-06-24 07:11 <apelete> larsc: do you think dma can be tweaked further ?
2014-06-24 07:13 <apelete> thinking about struct dma_slave_config values, I'm not sure about .dst_addr_width and .dst_maxburst

2014-06-24 13:23 <larsc> the largest the max burst values the better
2014-06-24 13:23 <larsc> but they depend on the fifo size of the mmc controller
2014-06-24 13:27 <apelete> larsc: yes, you told me before, but how do you compute .dst_addr_width and .dst_maxburst from the fifo size of the mmc controller ?
2014-06-24 13:33 <larsc> dest_addr_width sould be 4
2014-06-24 13:33 <larsc> and maxburst is in number of samples
2014-06-24 13:44 <pcercuei> larsc: good evening ;)
2014-06-24 13:49 <larsc> yea
2014-06-24 13:57 <apelete> larsc: do you mean I should keep .dst_addr_width = DMA_SLAVE_BUSWIDTH_4_BYTES and try a higher value for .dst_maxburst ?
2014-06-24 14:01 <larsc> DMA_SLAVE_BUSWIDTH_4_BYTES makes no sense for maxburst
2014-06-24 14:08 <apelete> ok, so that's what you meant by "maxburst is in number of samples"
2014-06-24 14:09 <apelete> larsc: I guess I'll have to compute a number of samples myself based on the fifo size of the mmc controller then
2014-06-24 14:10 <apelete> I'll take a look at other drivers to see how it's done, and work something out from there
2014-06-24 14:13 <Textmode> how can I check what version of the os I have running on my nanonote?
2014-06-24 14:16 <apelete> Textmode: if you're looking for kernel version then it's 'uname -a'
2014-06-24 14:17 <Textmode> apelete: whats the current one, for comparison? I'm getting 2.6.32.10 #1 PREEMPT Tue Jun 15 17:53:33 CEST 2010
2014-06-24 14:17 <Textmode> (which i'm guessing isn't the latest)
2014-06-24 14:20 <apelete> Textmode: last known kernel is 3.3.8 -> http://en.qi-hardware.com/wiki/OpenWrt_Software_Image#Image_2012-07-11
2014-06-24 14:21 <apelete> as you can see there latest actual OS release is Image_2012-10-24
2014-06-24 14:21 <Textmode> Hmm, not as bad as I expected. but still.
2014-06-24 14:22 <Textmode> oh well, I guess thats my task for tomorrow.
2014-06-24 14:22 <apelete> I'm running a 3.12 kernel btw, but I built it myself for development purpose
