printDeviceInfo:688: get 0x40E0 size : error -30

[magnumripper]

After #5 was fixed, that old Ubuntu (or whatever) machine I tested build clinfo just fine, but it fails at run-time with this message (after printing lots of information):

printDeviceInfo:688: get 0x40E0 size : error -30

The offending code

    if (*has_spir) {
        SHOW_STRING(clGetDeviceInfo, CL_DEVICE_SPIR_VERSIONS, INDENT "SPIR versions", dev);
    }

Not sure why *has_spir was true... where is it set?

Indeed, it lists all devices (including CPU) of the AMD platform, but fails when listing the CPU device of the Intel platform.

printDeviceInfo:688: get 0x40E0 size : error -30

Apparently, the Intel platform says it supports cl_khr_spir yet returns "invalid value" when queried with CL_DEVICE_SPIR_VERSIONS. So it's a driver bug and I guess you should just handle it.

On a side note, we also have a problem on the same last platform/device with getWGsizes:148: build program : error -11 [right before listing Preferred work group size multiple] but that is a soft problem listed to stderr without bailing. That may be another issue but I haven't looked into it yet. This too only happens with the Intel/CPU device, not the [same physical] AMD/CPU device.

Hmm, actually the platform says it supports cl_khr_spir - but does the device support it? That was not yet listed when error occured.

[magnumripper]

OK that was not it. The device does claim to support cl_khr_spir.

Thanks for the report. For the getWGsizes issues, it's something that I've seen happening with the beignet driver failing to creat a context, but it seems that in your case it's something worse (-11 is a failure to build the program). That's definitely better to have on its own bug report.

For the CL_DEVICE_SPIR_VERSIONS, we should be resilient to this kind of errors. Looks like it's time for that rehaul of the code that I've been planning on doing to make all property retrievals catch errors without killing the program.

Works fine in 8ecdc1b

Cool. Next thing will be to investigate the -11 on the program build. Could you open a separate ticket for that?
