Incorrect pci id for Asus RX 480 strix

[KayJay7]

Real issue

Upon better inspection, the id in the file is incorrect, as shown in this output of lspci -vnn:

...
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] [1002:67df] (rev c7) (prog-if 00 [VGA controller])
        Subsystem: ASUSTeK Computer Inc. Radeon RX 480 [1043:04fb]

The correct pci id is 1002:67df:1043:04fb while the file reports 1002:67df:1043:04fd (the last hex is different).
This is probably an error from the author or the pull request that added support for the card as here the same id as mine is listed.

On the pci id repository both ids are bound to the RX 480, so I think it's possible that some cards come with one and some with the other. I don't think it depends on the amount of vram, because my card has 8gb as well. Maybe both ids should be kept.

I still can't build the module, so I haven't tested it.

Old issue (No pci device found even though the id is in the pci_ids.h file)

I kept the old issue for the record, most of it is not relevant anymore.

I'm trying to use this module with an Asus RX 480 strix, and the module fails to detect it.

The output of dmesg | grep aura is:

On the third line, the module fails to find a valid pci device

The output of lspci -nn | grep VGA is:

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] [1002:67df] (rev c7)
0d:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Raphael [1002:164e] (rev c3)

On the first line, the 480 has id 1002:67df which coincides with the id on line 14 of the pci_ids.h file.

I would test the original repo (not your fork) to provide more info, but I fail to build it.

I identified the real issue and update the previous comment.

I have news, adding the pci id is not enough. As a matter of facts, this driver should only work for vega gpus end not polaris.

Vega gpus use the uc line (?) number 7, while polaris gpus use 6. this commit from hartmark changes the line to 7 to support the vega card he uses, so now the driver should only works for vega gpus.

I have confirmed that adding the pci id and changing the line works and I can succesfully control the rgb of my card.

This solves this issue
