08:46 <vishnup> wens: should we re-use in case sun8i-a83 pll6 is exactly same as sun9i-a80 pll4?

08:47 <vishnup> or we duplicate it and name it "sun8i-a83t-pll6" ?

08:49 paulk-collins has joined #linux-sunxi

08:51 <vishnup> wens: just a bit post different, so need to duplicate!

08:51 <vishnup> s/post/position

08:52 FDCX has quit [Ping timeout: 260 seconds]

09:02 <wens> you could probably re-use the get_factors function

09:03 <wens> vishnup: please also check if any other clocks can be re-used

09:04 yann|work has joined #linux-sunxi

09:05 FDCX has joined #linux-sunxi

09:05 <vishnup> wens: clock_output bit is not used in clk_factors structure. so, can just use "allwinner,sun9i-a80-pll4-clk" in A83T dts?

09:12 <sunxi_fan> hello, i'd like to ask a clarification about Mali..

09:13 <sunxi_fan> is the kernel driver source useful at all or the issue is about the "user level blob"?

09:14 <sunxi_fan> i've just seen this linux kernel tree from xilinx for their Zynq MPSoC with Mali 400MP2 on board..

09:14 <sunxi_fan> there's a staging driver here: https://github.com/Xilinx/linux-xlnx/tree/master/drivers/staging/mali

09:14 <sunxi_fan> is this useful for sunxi mainline too?

09:15 <wens> vishnup: no idea what that bit is for... check sdk?

09:23 <sunxi_fan> there's also some documentation on Mali in the Zynq MPSoc ref manual: http://www.xilinx.com/support/documentation/user_guides/ug1085-zynq-ultrascale-trm.pdf

15:04 <ssvb> sunxi_fan: thanks, the Xilinx manual indeed provides a nice high level overview of Mali400 hardware and even has a list of hardware registers with their names (but it does not really document these registers)

15:04 <ssvb> libv: ^

15:12 ir2ivps8 has quit [K-Lined]

15:15 <libv> right, nothing new in the overview tbh, and i never had to look at actual registers as the kernel driver takes care of such things

15:15 <libv> thanks though

18:30 <GeneralStupid> is somebody able to help me with orange pi pc and its clock frequency?

18:30 <GeneralStupid> i set the maximum in that fex file to 1.2 Ghz but it does not work

18:47 domidumont has joined #linux-sunxi

18:51 <ssvb> GeneralStupid: please define "does not work"

18:51 domidumont has quit [Read error: Connection reset by peer]

19:14 <GeneralStupid> ssvb: the board boots but cpufreq-info said max clock is still 1.54GhZ

19:16 <ssvb> GeneralStupid: have you converted your fex file to script.bin and put it into the right place?

19:17 <GeneralStupid> yes and yes

19:17 <GeneralStupid> if /boot/ is the right place

19:18 <ssvb> was the original script.bin there?

19:18 paulk-collins has quit [Quit: Quitte]

19:19 <GeneralStupid> yes (i copied it there)

19:20 <GeneralStupid> how can i look which clock my cpus have atm?

19:20 <ssvb> run the cpufreq-info tool or check the sysfs entries

19:22 <GeneralStupid> ...

19:23 <GeneralStupid> ssvb: http://paste.debian.net/341258/

19:23 <GeneralStupid> but cpufreq-set does not work

19:24 <ssvb> try "cpufreq-set -g userspace && cpufreq-set -f 1.2GHz"

19:25 <GeneralStupid> ssvb: looks goot: http://paste.debian.net/341259/

19:26 <GeneralStupid> the working line: cpufreq-set -g userspace && cpufreq-set -d 0.48GHz -u 1.0Ghz -r

19:26 <GeneralStupid> i think ~900 Mhz are more then enough for my use

20:54 <mx4> when partitioning your sdcards do you guys use there instructions? http://linux-sunxi.org/Bootable_SD_card#Partitioning

20:55 <GeneralStupid> mx4: i used an image for my orangepi pc and resized the root partition

20:56 <mx4> oh, i see. i'm trying to make an image for http://linux-sunxi.org/Prestigio_PMP3670B

20:57 <mx4> managed to make the uboot_with_spl but stuck at the partitioning part. i have mede the 17mb partition but can't find uImage in the sunxi folder

20:58 <GeneralStupid> did you already build a kernel?

20:59 <mx4> no... the kernel aprt is under the u-boot part so i figured i didn't need it stil (http://linux-sunxi.org/Manual_build_howto)

21:00 <mx4> well.. i think i know what i'm to do now :)

21:00 <GeneralStupid> i compiled it explicitly (make *params* uImage modules)

21:00 <mx4> you have stupid in your name but are far from it. i on the other hand seem to be the exact oposite :D

21:01 Swabbles has quit [Quit: Lost terminal]

21:01 <GeneralStupid> mx4: i chose this name when i was 14 :D

21:02 <mx4> hehe, some things tend to stick to you. like nicknames and boogers :D

21:03 <GeneralStupid> lol, yes :)

21:04 <mx4> its a bit old, but this is the picture that i had in mind http://cdn2.holytaco.com/wp-content/uploads/images/2009/12/booger.gif

21:04 <GeneralStupid> 1999

21:05 <rellla> jemk: wow, clever way how you solved the reg offset :) seems it would be possible to rebase most of my commits on new master

21:05 <rellla> i think i'll do that

21:06 <rellla> *some refactoring, too

21:13 <jemk> rellla: nah, pretty dirty, but it works

21:14 <rellla> no #ifdef still

21:14 Andy-D has quit [Ping timeout: 260 seconds]

21:15 <jemk> except the offset doesn't really depend on ve version, but more on which kernel you use

21:15 <rellla> any further commits planned?

21:17 <jemk> not really, there would be a lot to clean up, but i'd prefer to replace libvdpau with something v4l based

21:18 <rellla> i just think about (heavy) rebasing... in the meantime
