It’s just a pre-alpha version with kernel linux mainline 4.12-rc6. Based on mainline commit ID:

commit 8d829b9bb878904f3419af8003176a12910b94e8
Merge: 48b6bbe 8e8320c

    Merge branch 'for-linus' of git://git.kernel.dk/linux-block
    
    Pull block fixes from Jens Axboe:
     "This contains a set of fixes for xen-blkback by way of Konrad, and a
      performance regression fix for blk-mq for shared tags.
    
      The latter could account for as much as a 50x reduction in
      performance, with the test case from the user with 500 name spaces. A
      more realistic setup on my end with 32 drives showed a 3.5x drop. The
      fix has been thoroughly tested before being committed"
    
    * 'for-linus' of git://git.kernel.dk/linux-block:
      blk-mq: fix performance regression with shared tags
      xen-blkback: don't leak stack data via response ring
      xen/blkback: don't use xen_blkif_get() in xen-blkback kthread
      xen/blkback: don't free be structure too early
      xen/blkback: fix disconnect while I/Os in flight

1) Setup network

Note to plug in the LAN cable and run:

# echo "auto eth0" >> /etc/network/interfaces
# echo "iface eth0 inet dhcp" >> /etc/network/interfaces
# /etc/init.d/networking restart
Restarting networking (via systemctl): networking.service.
$ ifconfig 
eth0      Link encap:Ethernet  HWaddr 00:15:18:01:81:31

Scan WiFi hotspots:

#  nmcli d wifi list

hello,
today is a great day !
we have officially labelled mainline linux, I installed it and I can say eth0, wlan0 and hci0 do work,
1st impressions are very positive.

I’ve never seen any previous khadas rom that runs so weeeelllllll right from scratch

congrats to everyone that has contributed
keep up the good work, faith is returning to us customers when we see such a great achievement

I hope we’ll get out of alpha and beta soon

3

Can someone with buntu test this scenario and report if you have such problem which i reported there

4

Great news, i won’t be trying out this alpha, usb and sound are the reasons, but i hope most of the problems will be solved soon.

5

It managed to git clone micropython but was using serial console and maybe was using wlan0…
Please note that this rom uses krnl 4.12 rc6 and 4.13 seems out now and your issues was seen on rc4 and before.

6

According to https://www.spinics.net/lists/kernel/msg2535097.html
Usb support should come back in 4.13 as pull request re-adding usb was accepted

7

Well with wlan0 it was working also for me as I wrote there. Could you please setup eth0 and do same test? Two users of ArchLinxArm with mainline kernel did reported this, thus I would like to know this from an buntu User.

8

I’ve encountered the same issue, even with 4.12-rc7.

9

Would you like to share the kernel config, you’ve used to build the kernel?

I hope @numbqq and @Stuff did they own custom config with only stuff for Khadas VIM and not some generic (all enabled config).

11

Hi umiddelb,

You can refer to config for kvim_defconfig.

Thansk.

12

Hi numbqq

thank you for sharing. I’ve just tried a mainline kernel built upon this config (I assume you are using the meson-gxl-s905x-khadas-vim.dtb), but I still experience these strange network issues. You may try it by yourself by cloning the Linux source code repository via git, e.g.

 git clone --depth 1 --single-branch -b master https://github.com/ioft/linux/

If the download stalls, a simple ifdown / ifup eth0 (via serial console) will get the network connection operational again.

Cheers
Uli

Hi umiddelb,

When I use scp copy,I got the same issue,too.

# scp nick@192.168.1.253:/home/nick/ubuntu-base-16.04-base-arm64.tar .
 ubuntu-base-16.04-base-arm64.tar.gz             6% 2256KB 418.0KB/s - stalled -
14

ok, so let s add to the list of known issues this eth0 stalo during some heavy traffic.

I would also mention inability of nmcli to see my wifi ssid which uses channel 13

15

You can find it already here the one i found / reported / some of them got fixed.

16

Does https://www.spinics.net/lists/kernel/msg2535052.html mean usb2 support for vim arrives in mainline kernel soon ?

Patch for meson gxl usb support is here : https://patchwork.kernel.org/patch/9684303/
Would someone try to patch a 4.12 rc6 with this and build a test kernel for us to deploy?

17

This patch here adds an USB driver, but I need a dts related patch as well, since USB nodes are missing for GXL boards in arch/arm64/boot/dts/amlogic.

18

I’ve found this patch here. The kernel can see the root hub,

but non of the USB devices connected to the receptacle are recognized.

Ouch ! But good try anyway, tks.

20

unfortunately this is only 50% of what we need the other half is [0]. Devs are estimating to have USB mainline support in kernel 4.14.
