pci ids for newer amdgpu parts may not be known as all non-radeon ati display ids are matched in newer versions of amdgpu.
in dmesg unknown products take the form: vga1 at pci12 dev 0 function 0 vendor "ATI", unknown product 0x687f rev 0xc3 vendor "ATI", unknown product 0x687f (class display subclass VGA, rev 0x03) at pci12 dev 0 function 0 not configured amdgpu0 at pci12 dev 0 function 0 vendor "ATI", unknown product 0x687f rev 0xc3 The diff below will match when an unknown azalia device or other ATI device is present. Alternatively it could be more specific: ^vga*vendor "ATI", unknown product ^vendor "ATI", unknown product*class display ^amdgpu*"ATI", unknown product should already be covered by the "amdgpu" line of firmware_patterns Index: patterns.c =================================================================== RCS file: /cvs/src/usr.sbin/fw_update/patterns.c,v retrieving revision 1.5 diff -u -p -r1.5 patterns.c --- patterns.c 17 Nov 2022 13:30:21 -0000 1.5 +++ patterns.c 7 Dec 2022 00:44:39 -0000 @@ -90,6 +90,7 @@ main(void) printf("%s\n", "acx"); printf("%s\n", "amdgpu"); print_devices("amdgpu", amdgpu_devices, nitems(amdgpu_devices)); + printf("%s \"ATI\", unknown product\n", "amdgpu"); printf("%s\n", "apple-boot ^cpu0*Apple"); printf("%s\n", "athn"); printf("%s\n", "bwfm");
