<AneoX> apritzel: my board runs qt app with framebuffer. No x server. On mainline kernel, will it works with lvds lcd as i runs on sunxi-kernel?
<apritzel> I am not a graphics expert, but AFAIK the A20 is pretty well supported in this respect
<apritzel> not sure about the LVDS support, though
<apritzel> AneoX: you may want to check the Wiki
<AneoX> ok, thank you, i will try m-kernel in few days

<MoeIcenowy> wens: I remembered you mentioned A31s codec is different to A31
<MoeIcenowy> how can you enable audio for SinA31s?
<wens> MoeIcenowy: i made a mistake
<wens> they are the same
<Net147> testing mali r6p0 x11 blobs on A20...
<MoeIcenowy> Net147: How do you get it?
<NiteHawk> Net147: are those from the Mali450 release by ARM? (just wondering if those are compatible with Mali400)
<MoeIcenowy> wens: hahahahahahaha...
<MoeIcenowy> wow from NextThingCo
<MoeIcenowy> can CHIP directly use it?
<MoeIcenowy> mripard: ^
<MoeIcenowy> It's now the time to try to make sun4i-drm work on my A33 tablets
<MoeIcenowy> (one is just Q8, another is a trouble -- LVDS screen
JohnDoe_71Rus has joined #linux-sunxi
<Net147> MoeIcenowy: plaes was doing some work on LVDS... https://github.com/plaes/linux/commits/sun4i-lvds-wip
<MoeIcenowy> LVDS is not a trouble
<MoeIcenowy> I cannot even get sun4i-drm work on my Q8 tablet :-(
<MoeIcenowy> (Oh I mean it's not a trouble now
<Net147> waiting for build to complete as I compile everything from source...
<wens> MoeIcenowy: it's probably the panel dot clock
Gerwin_J has joined #linux-sunxi
<MoeIcenowy> wens: Is Q8 Panels general?
<MoeIcenowy> Can I just add two panels for Q8 tablets?
<Net147> NiteHawk: the Mali-450 blobs are not compatible with Mali-400
<wens> MoeIcenowy: the sun4i-drm tcon driver requires an exact match, which the clock driver cant provide
<MoeIcenowy> (But in that way the q8 dts will get divided into
<wens> MoeIcenowy: adding panels require giving a model name and exact timings
<wens> something we don't hav
<wens> *have
<wens> as everything is generic off the shelf in shen zhen :/
<MoeIcenowy> wens: ? I cannot understand things about clocks :-(
<MoeIcenowy> I'm only good at use <&ccu xxx> ;-)
<MoeIcenowy> wens: so u-boot video driver do not need a extact match?
<MoeIcenowy> Q8_A33_800x480_defconfig works well on my tablet
<Net147> MoeIcenowy: here is how to convert U-Boot LCD timing to simple panel definition - http://linux-sunxi.org/LCD#Mainline_Linux_.28simple-panel.29
<MoeIcenowy> Net147: I saw it
<wens> Net147: it's not the timings that's the problem
<Net147> wens: I see
<MoeIcenowy> wens: what's the problem?
Gerwin_J has quit [Ping timeout: 264 seconds]
<wens> MoeIcenowy: problem is we don't know the model of the panel, so we can't add it properly to simple-panel and use it
<MoeIcenowy> simple-panel do not receive "generic panel" patches?
<wens> if you look at sun5i-a13-q8-tablet you'll see i just picked a panel that has close enough timings
<wens> MoeIcenowy: you need an identifier at least?
<MoeIcenowy> allwinner,q8-tablet-lcd-panel-800x480
<MoeIcenowy> Or we just add a tablet's panel that is known to be compatible with generic q8 config and have its identifier?
<wens> problem is the panels don't even have useful markings , let alone finding datasheets for them
<MoeIcenowy> but at least the infomation on it is enough for buy another one on alibaba
<wens> which might or might not have the same timings?
<wens> and putting timings directly in the dt has been nacked
<wens> so you can't just export them from u-boot
<wens> (which would've been quite nice actually)
<MoeIcenowy> I think the "another one" must have the same timing :-)
<wens> MoeIcenowy: what other issues do you have with getting drm to work?
<wens> or is it just the panel not being accepted?
<MoeIcenowy> I haven't tried a lot...
<MoeIcenowy> but I have not started the kernel since added drm driver
<MoeIcenowy> seems to be problem from CCU
<MoeIcenowy> (and I want cpufreq feature for A33...
<wens> MoeIcenowy: cpufreq is best used with the thermal sensor (which is what i was waiting for)
<MoeIcenowy> but those ones WIP GPADC NACKed my ths driver in july
<wens> though I don't see why we can't add cpufreq first
<MoeIcenowy> (or june or august
<wens> given that we now run the cpu at full speed
<wens> just need to be careful not to add any OPPs beyond normal usage
<MoeIcenowy> wens: I never succeeded to add cpufreq support to A33
<MoeIcenowy> with both old clock driver and also ccu
<MoeIcenowy> in old clock add it freezes the system
<MoeIcenowy> in ccu add it make it run very slow (and cpufreq-dt returns cpuinfo_cur_freq as 32000!
<MoeIcenowy> (oh on boot it's ok but if I try to adjust the frequency, no wonder to which value, it goes to 32000
<Net147> MoeIcenowy: got es2gears_x11 running. EGL_VERSION = 1.4 Linux-r6p0-01rel0
<MoeIcenowy> net147: congrats!
<NiteHawk> nice :)

<TheLinuxBug> So is the new CHIP acceleration a firmware blob or actual progress in open source drivers?
<Net147> blob
<TheLinuxBug> figures
<TheLinuxBug> of course they made it sound like in their announcement that they actually made some real progress
<wens> getting a blob that is actually redistributable is progress nontheless
<TheLinuxBug> But other baords have had that in the past have they not?
<wens> TheLinuxBug: other as in?
<TheLinuxBug> I want to say the A10, but then again maybe I am just thinking about the fact I know I have used A10 and A20 with working firmware blobs
<TheLinuxBug> but they may not bee 'redistributable'
<wens> so you do understand :)
<TheLinuxBug> :) ok

<Net147> wens: the blob checks for hardware model and revision when you try to use it
<Net147> wens: I can make the kernel driver return the matching model and revision for Mali-450 but then it fails when trying to power up the GPU cores

<buZz> does h3 have cedar?
<miasma> the cedrus page i linked lists h3
<KotCzarny> Interested people are welcome to join the development channel #cedrus on Freenode IRC.
<miasma> maybe there could be some 'howto play videos with your allwinner device' page on the wiki, maybe there is
