Thanks for the reply.

Yeah, I would need the details. It would be nice if you can share those scripts 
with me.

I think the main difference is indeed the different architecture. There
is also the fact that the JSC i386 EWS runs the tests natively, but the
mips and armv7 EWSes cross-compile and run the tests on a set of remote
devices.

I guess it's not defined anywhere indeed. The scripts that start the
queues for the arm and mips EWSes define a bunch of env variables to
point to the cross-compiler and also add a few options in
JSCTESTS_OPTIONS, such as a  --remote-config-file and --memory-limited.
I can share these scripts with you if you need more details.

Hope this helps.

It is a port which aims to provide just JSC with minimum dependencies.

Yes. JSCOnly is supposed to work on all platforms including macOS and Windows. 
On macOS it's quite close to Mac port, but does not include Objective-C API.

[webkit-dev] Questions about JSC EWS queues

[Aakash Jain]

Hi All,

I am working on moving JSC EWS queues from old EWS to new EWS. I am trying to 
clearly understand various JSC EWS queues. I have few questions:

1) What does 'jsc-only' port represent? From 
https://trac.webkit.org/browser/webkit/trunk/Tools/Scripts/webkitpy/common/config/ews.json#L45
 

 it seems like Apple JSC EWS uses 'mac' port, while linux jsc EWSes use 
'jsc-only' port. Is jsc-only port specific to linux? Is there a corresponding 
jsc port for mac?

2) Is there any difference between the three linux JSC EWSes (JSC i386, JSC 
MIPS32el, JSC Armv7) apart from the architecture and few queues 
running/skipping tests? 

3) Where is the architecture for various linux JSC EWS queues configured in the 
old EWS code (e.g.: I don't see the architecture being added in 
https://trac.webkit.org/changeset/237001/webkit 
)? Is the queue configuration 
for various JSC EWS queues same, and the device connected to the queue actually 
decides the architecture?

Thanks
