Sometime earlier this month (8/24) my gpu,T600, was no longer recognized. I thought that it was on my end as a result of kernel updates (maybe, maybe not) so I reinstalled the client. No dice.

I took a hard look at the error message in the log at these lines
***************************snippet of log****************************************************

It is correct that there is no TU117GLM [T600 MOBILE] in gpus.json. Recall that I wrote "my gpu was no longer recognized." It appears that some time this month gpus.json must have been updated and the record relevant to my gpu was screwed with.

clinfo identifies this cpu as 'NVIDIA T600 Laptop GPU', so it is correct that gpus.json does not contain a record with the description field value "TU117GLM [T600 Mobile]".

As a expedient I edited cpus.json description field for the suspect record: "vendor": 4318, "device": 8122, "type": "nvidia" to be the value that clinfo returns, i.e. "NVIDIA T600 Laptop GPU." Now, everything is just peachy

So, what happened to gpus.json?

oops, cut-and-paste crash: ...cpus.json does not contain a record for the device name "NVIDIA T600 Laptop GPU"..... but it had.

Not sure what happened to the gpus.json file, the entry does exist in the GPUs.txt file available online. I can bring it to the attention of the developer, perhaps there was a problem with the generation of the most recent .json file for distribution. It was in the file my system downloaded on Aug 11th.

The maintainer checked, the gpus.json is correct on the server. He did notice an error in your log that I didn't: Check your driver installation, you may need to reinstall after a kernel update.

As a note, the driver description in the gpus.json entry does not need to match what is returned by clinfo. That file is just used by the client for display purposes and could even be left empty. The client uses the PCI device ID for manufacturer and its assigned ID number for the GPU to determine if a GPU is supported.
