Android 8.1.0 display slow #1

hello,
I flashed Android 8.1.0 on my Hikey960. The result is that I have a slow
display.. probably, the hardware acceleration is not supported by the Kernel
4.4.
Unfortunately the "release tags" are made on internal branches, so we
cannot test them on the devboards before the tags are made. Thus they
tend to have issues like this.
For this reason, AOSP/master is the only branch that is supported on
HiKey/HiKey960.
So I'd recommend re-running repo sync specifying master as the branch,
then rebuilding and reflashing.
I would like to update the kernel. When I do it (with v4.9), the system is
not booting anymore.
Do you have any solution on this ?
The kernel 4.9 is working well with Android P but I prefer Android 8.1.0 for
my development.
Unfortunately I don't have enough details here to understand the
problem. Can you explain what you mean by "update the kernel"? Can
you clarify which kernel branch exactly (or the HEAD sha1sum would be
most helpful) you're trying to use?
thanks

Hello John, Thank you for the reply. I would like to follow this part of the Google Documentation to update the Kernel of Android 8.1.0 branch https://source.android.com/setup/devices But after doing it, it looks like the system is not booting anymore. Do you know what is wrong on this action? Thanks for help. |
I finally resolved every problems with the master branch. Thank you for helping. Do you know why when I try to build for aosp_car_arm64_userdebug I got errors for hikey ?

The following types on /vendor/ must be associated with the

Apologies, I don't have much experience with that target. It looks
like the sepolicy files needs some tweaking.

I don't really know which is the best way to have a car HMI on my Hikey960.
I know there's some external efforts going on, for example here:
https://github.com/HiKey960-Car
You might give that a try? I've not personally tried to build or run it though.
thanks
