> 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?

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

> 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?

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.

> 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?
