Posted: Sat Oct 28, 2023 3:15 pm Post subject: Waydroid support - full kernel config |
|
|
I was messing around for a quite a bit to get this piece of unsupported software running under Gentoo Linux (which I emerged from the guru overlay). The biggest problem I encountered was dealing with setting up my custom kernel config correctly so that it supports functionality Waydroid expects from it. As an a easy solution you can just get the sys-kernel/gentoo-kernel or gentoo-kernel-bin package and be done with it, but I'm one of those people that likes to optimize things as much as possible with a custom kernel configuration (hence I use Gentoo). So, for those who need this piece of software, here's a list of things that should be enabled/disabled within the kernel to get Waydroid working with full functionality. Hope this will be useful to someone out there, so that they won't spend time on looking for info on what needs to be enabled/disabled to get it to work, because the official documentation doesn't mention any of this (except for like one or two options).

The settings were enabled/disabled for gentoo-sources-6.5.7 and I believe it'll work for newer versions as well. I should also mention that this is without support for apparmor. The use flag was disabled and therefore nothing for it was enabled in the kernel itself. _________________ If dreams were horses, beggars would ride. |

hi,
I like to mark M if is eligible,
it is a must the Y to get working waydroid?,
today I was trying to use waydroid but i can't,
do you use openrc? me yes,
config_cgroup_bpf depens on a kernel systemd option
Selected by [n]: - GENTOO_LINUX_INIT_SYSTEMD [=n] && GENTOO_LINUX [=y] && GENTOO_LINUX_UDEV [=y]

You can set most as modules, but I'm not sure what's the point? it works either way, but getting most of these as modules is going to be more of a waste of time really. I would suggest to just build 'em into the kernel or use sys-kernel/gentoo-kernel-bin if you need waydroid for "one time uses", but that'll mean you would have to load a different kernel every time you need waydroid for something.
papu wrote: | do you use openrc? me yes, |
Yes, I'm using OpenRC. Don't forget that Waydroid has a service as well.
You can enable it with:
rc-update add waydroid default
-- edit --
Btw, just because waydroid requires systemd kernel support doesn't mean you need to switch to systemd. I've got elogind as a global USE flag and everything is fine that way under OpenRC. Some options are dependent on other options, otherwise they stay hidden and you need to press Z to see them within the list and check via HELP dependencies that should be enabled first, before you can enable an option you're looking for. _________________ If dreams were horses, beggars would ride. |

i prefer that way for better control of myself , since i am used to configured amdgpu drivers in kernel like M, and bzimage also is small
p.d: well at the end it not works i just gets and screen with animation from right o left all time but nothing more happens

@papu
That's something already. When I was figuring this stuff out, I couldn't get passed some sort of netfilter script trying to start for a long time, before I got at least the window of Waydroid popping up.
Yet, something is still missing in your kernel by the looks of it, but I can't really tell hat exactly. Try doing a test with sys-kernel/gentoo-kernel-bin just to confirm this is an issue with the kernel. Also I'd like to point out that I've got all those modules required by waydroid as built into the kernel itself and it works fine. I haven't really tested with mostly modules... theoretically it shouldn't be a problem, really... but you might want to try building them into the kernel instead.
You can also check the log with the command waydroid log and post it here. It could help pinpoint what's wrong.
If it'll work with sys-kernel/gentoo-kernel-bin, but not with your custom kernel and built-in modules, then I'll recheck the full list of required options that should be enabled/disabled and make sure nothing above is missing here.The stuff I posted above is just what should be enabled for the gentoo kernel. _________________ If dreams were horses, beggars would ride. |

with kernel-bin seems it works, but i cant install barely nothing from fdroid and neither firefox apt(from apt mirror), the container works very fast.
to find out what kernel-bin option(s) are missing to my kernel sounds too much hard work and I am already using a qemu-androidx86
why do you disable nftables? It is needed for waydroid according to post messages of emerge

have you tried that thing? https://github.com/casualsnek/waydroid_script _________________ "~amd64" --cpu 7700 non-x --DDR5 2x16GB 6000MHz --gpu RX 470

I didn't mean you have to disable all netfilter options in the kernel. I was just mentioning that due to improper configuration I would often get a netfilter error in the waydroid log. Something about a script... You only have to disable CONFIG_NF_TABLES [=n] and CONFIG_NFT_COMPAT [=n] because for some reason those two break waydroid if enabled (I tested it and it does).
papu wrote: | but i cant install barely nothing from fdroid and neither firefox apt(from apt mirror) |
I don't know much about that. I just need waydroid for like two apps... I didn't really test much really with the apps, but I am aware that many games work under waydroid, which is a pretty cool achievement for the devs.

Yes, which is why I spent a lot of time to get this thing to work on my system.

Well, I can give the full and filtered list of required options, not only those that for the gentoo kernel. I have everything saved anyway, just need to organize it and post. I just thought it would redundant to mention options that are already enabled by default within the gentoo kernel. Of course after that you would have to figure out the configuration by yourself. I'll post it a bit later when I have time. Perhaps it would be of use to someone else. Btw, most of the list is taken from PostmarketOS (made for Linux phones and stuff like that).
I should really just post the links here:
https://gitlab.com/postmarketOS/pmbootstrap/-/blob/2.0.0/pmb/config/__init__.py#L458-572
https://gitlab.com/postmarketOS/pmbootstrap/-/blob/2.0.0/pmb/config/__init__.py#L349-393
Some options I had to find out from other sources, though...
Yes. It works until you update android itself (at least with the smart dock thing). It seems alright, but I remember having android break two times because of it and I had to manually delete everything waydroid related and re-emerge the whole thing, and do waydroid init as well to redownload the image and everything. The clean-up command from the waydroid troubleshooting doc doesn't really delete everything and might not help if something is broken badly, which this script is somehow capable of doing. _________________ If dreams were horses, beggars would ride. |

finally I maked it works , there was a problem with the net , I had no internet iinside waydroid, i figure out the options for that, and now i have internet:
Code: | [*] CONFIG_IP_ADVANCED_ROUTER
[*] CONFIG_IP_MULTIPLE_TABLES
[*] CONFIG_IP_ROUTE_MULTIPATH
[*] CONFIG_IP_ROUTER_VERBOSE |
now i have to test waydroid to see how it works and waydroid script..I don't know if it will be the subsitute of my curren qemu+androidx86 that works like a charm right now.
On the other hand the config of gentoo-kernel-bin it is very instructive and will help me a lot.

I checked and those options are enabled by default in the latest sys-kernel/gentoo-sources (6.6.1). Looks like this is something that you disabled yourself earlier. _________________ If dreams were horses, beggars would ride. |

yes I know, I have been using my .config, as cleaner as posible, for a long time and sometimes is needed o add some stuff
however, I've decided to keep using the qemu androidx86 while of waydroid have a great potential has problems righ now, at least on my gentoo.
Moreover, the wayland in kde plasma is not mature enough, and it giving to me some extra problems.
On the other hand figuring out inside the kernel net stuff has helped me optimizate my .config a bit more. _________________ "~amd64" --cpu 7700 non-x --DDR5 2x16GB 6000MHz --gpu RX 470 |

Yeah, I hear ya. I disable as much as possible as well to make the kernel smaller. Glad you figured it out, and yes, I agree, it seems waydroid needs more time to mature. At least it's good enough for my use case. It actually makes me want to try out a linux phone again. It's something that is pretty major for such a device, considering the lack of mobile optimized software on those things. ![Smile :)](images/smiles/icon_smile.gif) _________________ If dreams were horses, beggars would ride. |

Nice thread.
I have a basic kernel setting that tries to mach hardware feature.
When a new feature is required I template the previous with another CONFIG_LOCALVERSION.
Despite it has drawbacks I favor <M> when possible.
Will likely seed another kernel for waydroid sooner or later, as far as I can tell.
Thks 4 ur attention, interest & support. _________________ USE="-* ..." in /etc/portage/make.conf here.

I guess I could drop that in /etc/kernel/config.d. Needs a little sed/awk to be compatible, but that's not a problem. _________________ ..: Zucca :..
