Possible to build chromeos without chrome

[Tien Hock Loh]

Hi

I'm trying to port/enable a minimal version of ChromiumOS without Chrome/Chromium that runs on RISC-V target. Would it be possible to skip chrome/chromium browser build and still able to build and boot the target?

I saw the chromeless_tty USE flag, but couldn't really figure out what that is. 

Thanks

did you create a board overlay and then set USE=chromeless_tty in it ?

you're going to run into a lot of failures due to missing seccomp failures for riscv64.

Yeah I just followed FydeOS’s pi4 setup and use chromeless_tty. It looks like it can proceed without chrome browser.

 

Yes a lot of seccomp failures, but temporarily, I have mode duplication of arm64’s policy and use it as riscv’s. Any issues you see reusing arm64’s seccomp policy?

i've never compared the two syscall tables.  they would have to use the same set of syscalls and use the same signatures.  you could prob use docs/constants/syscalls.py to generate tables to see what ones arm64 has that riscv doesn't.

i'm assuming you're only testing riscv64.

I see, I’ll take a look at the syscalls.py. Yes I’m currently testing riscv64, and will try to enable it and start upstreaming the code if possible.

 

Thanks

You might find this CL helpful to build a "headless" server:

It's very much out of date but should provide outlines on how to build w/o chromium.

cheers,

Sorry for the late reply. Seems like a good information for me. Thanks!
