so Im trying to build 4.2 for sunxi h3, and... well basically I'm set with the kernel downloaded and the like, but I do not know how to form the make command. Yes, I've tried the one @ wiki.

wens: ah from https://patches.linaro.org/4045/ it looks like DDR mode is only available in 8 bit mode, not 4, so it's not available anyway (unless allwinner put 8 bit mode on the NAND pins of mmc2 and 'forgot' to document it
<oliv3r>
but ddr as well as 8 bit mode works in either power class it seems
<oliv3r>
wens: and that makes me think that power selection is up to the regulator. does the regulator have gpio bindings to toggle voltages? or does it always assume there's an PMIC or something controlling voltages? (a gpio is a very simple regulator :)

as for ddr, there are sd and emmc variants i think

I have ubuntu 14.04 running on Mele M3 using latest mainline kernel and latest u-boot. Everything is working except WiFi. My hardware is Realtek RTL8188ETV. I have enabled support for it in the kernel (it's staging driver) but now I can not find the firmware file anywhere online. Can someone help?

@wens, im running your patches successfully on a cubieboard 4 now . im running all 8 cores but deactivated the slow ones via /sys. but when i cmopile the same kernel with the same config on cb4 with 2 cores or on cubietruck , i get the same performance .... but cb4 should be around 3 times faster .... any ideas`?

@wens is there a way to control / check cpu clock ?
<Dodger78>
or ram clock
<NiteHawk>
Dodger78: if you have cpufreq support, you should be able to use /sys/devices/system/cpu/cpu?/cpufreq/ for that. or the cpupower utility
<Dodger78>
@wens , somehow not even though the kernel option is active ( and the same config works on my cubietruck )

Hey guys, for the A20, anyone know what the expected max speed of the SATA port is, and is there anyway to tune it? I read somewhere it can be effected by the cpufreq settings, however, have not seen any specifics on what works best besides changing the govenor to ondemand
<TheLinuxBug>
I seem to get around a max of 70M/sec
<TheLinuxBug>
using the deadline scheduler
<TheLinuxBug>
CFQ maxed at about 60M/sec
<TheLinuxBug>
Was hoping to at least avail a reasonable 100 if its possible
<TheLinuxBug>
More specifically this is on an Bananapi
<TheLinuxBug>
thanks in advance for any responses ;p
<RSpliet>
TheLinuxBug: well, there is the matter of DMA, you might want to specify your kernel so someone else might be able to tell you more about it :-P
<TheLinuxBug>
Linux openmediavault 3.4.108+ #2 SMP PREEMPT Mon Aug 24 08:55:25 UTC 2015 armv7l GNU/Linux
<TheLinuxBug>
Bananian + Openmediavault
<TheLinuxBug>
so its the openmediavault dist they put out
<TheLinuxBug>
I recvompiled kernel with Sata PM support
<TheLinuxBug>
though I am now reading that Igor may have a different kernel version that works better
<TheLinuxBug>
for 3.19.7
akaizen has joined #linux-sunxi
<TheLinuxBug>
not sure
<TheLinuxBug>
maybe the newer kernel can't handle it the same
<TheLinuxBug>
will have to attempt compiling a 3.19 kernel later
<TheLinuxBug>
but anyways, in the mean time anything I can check besides the schedulers (deadlin/cfq/noop) and cpufreq settings that would improve throughput?
<TheLinuxBug>
I am currently using deadline
<TheLinuxBug>
and I have cpufreq set to ondemand
<TheLinuxBug>
Unlike other platforms sequential SATA transfer rates on A10/A20 scale somewhat linearly with both cpufreq settings and DRAM clock. In case you use the wrong cpufreq settings it's impossible to achieve maximum SATA performance (eg. using the ondemand governor without io_is_busy setting).
<TheLinuxBug>
I did this from the Wiki on SATA
<TheLinuxBug>
I set the io_busy_setting as well
<RSpliet>
oliv3r: what can you tell this chap about upstream sata support? does the controller (really?) have it's own dedicated DMA engine?
<RSpliet>
is it really just that slow? :-P
