00:18 <jernej> megi: Kodi uses drmModeAddFB2WithModifiers() for that. You give same buffer handle for each plane and set offset accordingly

00:19 <megi> nice

00:23 TRS-80 has quit [Quit: WeeChat 2.3]

00:24 <jernej> I guess drmModeAddFB2() will be enough for your case

00:24 TRS-80 has joined #linux-sunxi

00:25 <megi> yeah, I see how I can do that

06:12 <luke-jr> hmm, I guess I might have trouble finding a place to buy it :x

06:12 <luke-jr> any ideas where to get A20-OLinuXino-LIME2-e16Gs16M

06:12 <luke-jr> in the USA*

06:14 <luke-jr> or comparable (main differentiator is the GPIO count..)

06:17 <DonkeyHotei> is that still made?

06:17 <jernej> megi: fixed, thanks!

06:17 <jernej> does it work on A83T with that fix?

06:23 <luke-jr> DonkeyHotei: their site claims it is made forever

06:23 <luke-jr> also open source hardware, so in theory anyone could produce them?

06:24 <luke-jr> haven't really found anything newer that's comparable :/

06:25 <luke-jr> I know I need at least 77 GPIOs

06:26 <plaes> there are spi or i2c gpio expanders

06:29 <plaes> and another option is multiplexing (in case you need gpios for driving leds)

06:31 <luke-jr> I need them as inputs constantly being scanned? ☺

06:31 * luke-jr ponders if there's anything that would just notify him when they change

06:32 <plaes> ok, then multiplexing won't work

06:34 <plaes> or it might... :D

06:51 <KotCzarny> maybe some gpio2usb ?

06:51 dddddd has joined #linux-sunxi

06:51 <KotCzarny> maybe you should just hack some keyboard :>

07:30 <smaeul> you could repurpose a CSI connector for 10 more GPIOs, or the wifi connector on Pine64 for 19 more GPIOs

07:44 AneoX has joined #linux-sunxi

08:01 <DuClare> I'm pretty sure there are I/O expanders with interrupt lines too

08:06 <DuClare> For example: http://ww1.microchip.com/downloads/en/devicedoc/20001952c.pdf

08:07 <miasma> even the cheapest 8-pin ebay i2c-gpio expanders have one interrupt pin :)

10:27 <KotCzarny> and if you are into linux/open source phone, pinephone could be better (once there is a stable OS for it)

10:27 <KotCzarny> 150usd is quite good price if you ask me

17:57 <solderfumes> Hello!

17:57 <mru> are those fumes from rosin flux?

17:57 <solderfumes> I have attached a Qualcomm Atheros QCA6174 to the MMC1 SDIO port of an Allwinner H6

17:58 <solderfumes> Getting the following error after sorting out the firmware:

17:58 <solderfumes> sunxi-mmc 4021000.mmc: unaligned scatterlist: os 40 length 11

17:58 <solderfumes> sunxi-mmc 4021000.mmc: map DMA failed

17:58 <solderfumes> I was wondering if anyone else hit this problem

17:59 <mru> the message is pretty clear

17:59 <mru> something is attempting to use a misaligned buffer for dma

17:59 <solderfumes> In effect, I can use the interface to list the wireless AP's, but connecting is not possible

18:00 <solderfumes> yes, mru. So I should fix this in the ath10k_sdio driver?

18:00 <mru> probably

18:00 <solderfumes> or is the sunxi-mmc driver wrong?

18:00 <mru> well, it works with broadcom sdio wifi...

18:02 <solderfumes> since it also says quote: "ath10k_sdio mmc1:0001:1: WARNING: ath10k SDIO support is work-in-progress, problems may arise!"

18:02 <mru> looks like they did

18:03 <solderfumes> Indeed it do.
