11:51 <steev> sjoerd: okay finally had time to play with the u3... so, mainline u-boot, and mainline git... using multi_v7_defconfig... no networking, plugging in an rt2800usb wifi adapter... it powers up, but doesn't load the modules for it either...

11:51 <steev> modprobing manually doesn't give me a device either

11:53 <sjoerd> what does lsusb tell you after boot

11:55 <steev> that i don't have usbutils installed

11:55 <steev> lemme do that in my rootfs and then rsync it

11:55 <sjoerd> also check if you have SMSC95XX build

11:56 <steev> i do have a drivers/net/usb/smsc95xx.o

11:56 <steev> CONFIG_USB_NET_SMSC95XX=y

12:11 <sjoerd> do also try exynos_defconfig just in case

12:13 <steev> okay, will try exynos_defconfig, so rebuilding the kernel... gonna go kill myself a bit while that runs

12:21 <steev> yeah, exynos_defconfig gives me an eth0

12:32 <steev> alright, so booting and got network, bedtime

12:33 <steev> thanks sjoerd

12:53 <sjoerd> \o/

12:54 <sjoerd> Would be good to figure out what's missing in the multi_v7

22:54 <steev> sjoerd: is the dma use iommu important? that's turned on by exynos but not multi_v7, multi_v7 doesn't turn on ARCH_EXYNOS3, or EXYNOS5420_MCPM but i don't think that affects the 4412, exynos turns on ARM_CCI, a couple of SPI changes, but i don't think that should affect things... EXYNOS_THERMAL isn't enabled in multi_v7, nor is the S3C2410_WATCHDOG, ah, hm,

22:54 <steev> shouldn't USB_EHCI_EXYNOS=y be enabled?

22:54 <steev> that's enabled in exynos_defconfig but not in multi_v7

22:55 <steev> and USB_DWC3 isn't set in multi_v7

23:14 <sjoerd> steev: USB_EHCI_EXYNOS=y sounds like what you're looking for

23:15 <sjoerd> the dwc3 doesn't matter for exynos 4 iirc

23:16 <sjoerd> but USB_EHCI_EXYNOS is your usb 2 controller, so without that you won't get usb thus no network on the droid

23:16 <steev> yep, i figured

23:18 <sjoerd> woth sending a patch enabling those things on multi_v7 though

23:18 <sjoerd> *worth

23:18 <steev> yeah, i don't remember the proper way to add things to the defconfig

23:20 <sjoerd> scripts/kconfig/merge_config.sh is useful

23:21 <steev> i'm going to add each one individually and test that they work first

23:34 <steev> sjoerd: hm, so that spits out what all the differences are

23:35 <steev> and kinda sorta makes a .config if you don't add -m, but it's not entirely without issues either - but either way, testing the build to make sure it... uh... builds
