[Apache TVM Discuss] [Development] Build for ARM host

2022-02-23 Thread yuvalNR via Apache TVM Discuss


Hi,

I would like to use relay compiler to build for ARM host. The target device is 
also ARM.
for X86 **(target="llvm")** I can easily use

`export_library(lib_export_path)`

I get a .so which can be loaded by runtime to create an executor factory.

For ARM, I build with **target="llvm -mtriple=aarch64-linux-gnu"**,
I can then export to a tar file, where I have 2 object files.

**I get a linker (ld) error when trying to export to .so though.**

do I need to do something like this:(?)

 `cross_compile = 'aarch64-linux-gnu-c++' `

`lib.export_library(lib_export_path, cc=cross_compile)`

I did not check since I don't have the ARM toolchain installed so it would 
fail. I assumed that it should work since llvm compiled to ops to ARM object 
files.

Thanks for the help

[Apache TVM Discuss] [Development/pre-RFC] [RFC] Remove CODEOWNERS

@comaniac thanks for your comments!

Improve the PR template to guide the contributors about how to improve the PR 
visibility. We actually have this already but seems not effective. Pro: it is a 
simple change. Con: it may be ignored by most contributors.

I agree we have this, I'm not sure it scans very well (for example, the links 
are in Markdown so someone isn't going to mentally parse those and render them 
in their head). Perhaps we can improve the template and make it a bit more 
organized.

Improve the cc-bot to do more. For example, if the cc-bot finds no @ in the PR 
body, it replies the PR saying that it is encouraged to cc someone from the 
community for visibility and here is the code owner list. Pro: this will 
definitely get the attention by PR author. Con: it needs more changes to the 
cc-bot.

I really like this idea. @driazati do you think this would be a big change? 
seems like it's pretty related to the PR ping bot.

While our docs could use some consolidation, we already link to our 
contributing guide in the existing [PR 
template](https://github.com/apache/tvm/blob/main/.github/PULL_REQUEST_TEMPLATE.md).
 I don't think we shouldn't expect new contributors to read through a docs just 
to find who to tag in their PRs, we should have a constant rotation of 
committers monitoring new PRs and sending them to the relevant people. The 
process could look like:
* Check https://github.com/apache/tvm/pulls for PRs with a `triaged` label (and 
auto-mark PRs from contributors `triaged`)
* Briefly inspect the PR topic / changes and assign reviewers directly / tag 
people via `@`-ing them
* Add the `triaged` label

It would be simple to have the PR ping bot tag some people if there has been no 
activity on a PR and the author is new after a quiet period of a day.

Github teams is definitely a good idea
[/quote]

I [filed an issue with ASF 
Infra](https://issues.apache.org/jira/browse/INFRA-22864) to see if we can get 
them through GitHub teams but it looks like we will end up having to re-create 
it ourselves

I have the same problem. Do you have any solution?
