Custom Kernel still necessary?

[derjohn]

Hi,
Do we still need that 4.16.0-rc3 kernel?

Did anyone try to go with Ubuntu's Mainline PPA, e.g.

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16.5/

?

Hans once stated that with 4.17-rc1 last required patches for USB-C should be in mainline, we are there, so it's possible we can switch to mainline without great issues :)

I just need to make some tests

[derjohn]

I tried 4.17-rc2 and can confirm that my i915 graphics issue is resolved. (I had sometime strange artifacts when dragging windows mit KDE). Didn't check USB, though.

I am using the 4.17 rc2 from the https://github.com/jwrdegoede/linux-sunxi repository using the .config from https://github.com/petrmatula190/gpd-pocket-kernel on 17.10 image with no issues found so far.
(I got a bit scared when I saw 4.17 when I was expecting to see 4.16 rc6 messages...)

I can report some Wifi issues, had some packet loss and and an unknown condition the Wifi NIC disappeard (maybe it was after suspend?)

[petrmatula190]

@Morantz Did you builded kernel with my latest config? I don't belive. Because all my builds after 4.16rc6 have broken charging, baterry and charging sensors not presents in /sys and charging speed is only 5V/3A.

[Morantz]

Yes I had. Have since reverted to 4.16RC6 which works. I think 4.17 was also messing with sleep functions. Battery levels in AM after closing lid would be VERY low. Also, boot time was in the minutes to get to login screen when using 4.17.

[Morantz]

Are you going to update it for 4.17?

[petrmatula190]

@Morantz Not now, I am trying new build around 2-3 week, but i belive to full working final kernel 4.17 or 4.18. Maybe, mainlike will be better in future.

[Morantz]

@petrmatula190 You should probably change your directions to show:
git reset --hard origin/v4.16-footrail
when pulling from https://github.com/jwrdegoede/linux-sunxi so that a version 4.16 kernel is built, not a 4.17. Thank you for all your hard work supporting us users!!!

[petrmatula190]

@Morantz Thanks for tip. Until now, I am using
make clean && git fetch origin && git reset --hard origin/master && git pull
But i have the same result when i delete and download clean repo again.

This is my fisrt steps with github :-)

[derjohn]

Any chances for a 4.17-based kernel? Even on Hans tree?

[Morantz]

I am using the one from Hans tree, which is at 4.17rc3. Works great on a 17.10 image. On my 18.10 Budgie image, the screen goes right to sleep before the login screen comes up. This doesn't happen with 4.16rc6 image.

[petrmatula190]

@Morantz Can you share your .config? If I remember, this must be set everytime:

CONFIG_MATOM=y
#CONFIG_GENERIC_CPU is not set
CONFIG_BACKLIGHT_PWM=m
CONFIG_LEDS_PWM=m

I changed only this parameters in Hans default .config and try build.
