Can not get memory read/write bandwidth on ARC A770

[wejgan]

In previous versions, such as 1.2.27, it can get memory read/write bandwidth through the GPUDeviceStub::toGetMemoryReadWrite member function.

But in the latest release version, such as 1.2.36, it can not get memory read/write bandwidth on ARC A770. This is because the maxBandwidth value obtained from the driver is 0.

So it better to decouple Read/Write bandwidth from total bandwidth utilization. Thanks.

Latest release is V1.2.39 i.e. quite a bit newer. Could you upgrade and check whether the issue is still there, and close this, if not?

Note: I'm not a developer in this project, but I've noticed that memory BW info has come and gone in last several years depending on which exact FW, kernel driver, user-space and XPUM version I've used. I assume this has been because their APIs have changed, and there's no info which exact versions support each other.
