Re: [PATCH v3] arm: rust: Enable Rust support for ARMv7

[Manish Shakya <msh.shakya@gmail.com>]

I followed the Documentation/rust/testing.rs document to test more. It 
seems that only the KUnit test is possible, while the other two tests 
are not feasible in a cross-compilation setup. What other tests need to 
be performed?

The KUnit test passed.

[    1.162374] # rust_doctests_kernel: pass:128 fail:0 skip:0 total:128
[    1.162388] # Totals: pass:128 fail:0 skip:0 total:128
[    1.162401] ok 1 rust_doctests_kernel

Here is my current setup:
