Dear AMD Linux folks,
Using Linux 4.18.0-rc5+ I get the warning and error below in the logs.
I am using a Ryzen 3 2200g.
```
$ dmesg
[ 0.000000] Linux version 4.18.0-rc5+ (paul at tokeiihto) (gcc version 8.1.0 (Debian 8.1.0-10)) #1 SMP Tue Jul 17 11:43:33 CEST 2018

```
The messages are from the code below.
```
$ vim drivers/gpu/drm/amd/amdkfd/kfd_device.c
[â?¦]
305 static const struct kfd_device_info *lookup_device_info(unsigned short did)
306 {
307 size_t i;
308
309 for (i = 0; i < ARRAY_SIZE(supported_devices); i++) {
310 if (supported_devices[i].did == did) {
311 WARN_ON(!supported_devices[i].device_info);
312 return supported_devices[i].device_info;
313 }
314 }
315
316 dev_warn(kfd_device, "DID %04x is missing in supported_devices\n",
317 did);
318
319 return NULL;
320 }
321
322 struct kfd_dev *kgd2kfd_probe(struct kgd_dev *kgd,
323 struct pci_dev *pdev, const struct kfd2kgd_calls *f2g)
324 {
325 struct kfd_dev *kfd;
326 int ret;
327 const struct kfd_device_info *device_info =
328 lookup_device_info(pdev->device);
329
330 if (!device_info) {
331 dev_err(kfd_device, "kgd2kfd_probe failed\n");
332 return NULL;
333 }
[â?¦]
```
Can my ID just be added? Otherwise, if itâ??s expected that the probe function
can fail, the log level shouldnâ??t be an error?
Maybe something like below would be more clear, that it is expected.
> DID 15dd is missing in supported_devices and not supported yet.
Kind regards,
Paul
