larsc: deactivated the dma completion callback last night to see if dma transfer fares better

larsc: do you think dma can be tweaked further ?
07:13
<

thinking about struct dma_slave_config values, I'm not sure about .dst_addr_width and .dst_maxburst

the largest the max burst values the better
13:23
<
larsc >
but they depend on the fifo size of the mmc controller
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 ?
13:33
<
larsc >
dest_addr_width sould be 4
13:33
<
larsc >
and maxburst is in number of samples
13:44
<
pcercuei >
larsc: good evening ;)
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 ?
14:01
<
larsc >
DMA_SLAVE_BUSWIDTH_4_BYTES makes no sense for maxburst
14:08
<
apelete >
ok, so that's what you meant by "maxburst is in number of samples"
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
14:10
<
apelete >
I'll take a look at other drivers to see how it's done, and work something out from there
14:13

how can I check what version of the os I have running on my nanonote?
14:16
<
apelete >
Textmode: if you're looking for kernel version then it's 'uname -a'
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
14:17
<
Textmode >
(which i'm guessing isn't the latest)
14:21
<
apelete >
as you can see there latest actual OS release is Image_2012-10-24
14:21

Hmm, not as bad as I expected. but still.

I'm running a 3.12 kernel btw, but I built it myself for development purpose
