Re: kaveri_mec2.bin file missing

[Riza Dindir <riza.dindir%gmail.com@localhost>]

Hello,

Here is what I try to accomplish. I could not find the bios for the
0x1002/0x6604 device. So I thought that I could just disable this
device, and use the Kaveri device (0x1002/0x1309), since I have that
bios.

I have put the two files listed above (by RVP) to the
"src/sys/dev/microcode/radeon/" directory. I also changed the
configuration to only include the radeon device that is the
0x1002/0x1309 Kaveri device. Did add the KAVERI_mec2.bin to the
MODULE_FIRMWARE definitions in the radeon_cik.c file (since this was
missing). But this failed to load the microcode. It does fail in the
function "cik_init_microcode".

I have put these bin files into "src/sys/dev/microcode/radeon/". Isn't
this the correct path to put these bin files in?

Are the file names in this directory case-sensitive? Although in the
"src/sys/dev/microcode/radeon/" directory all the bin files begin with
capital letters (KAVERI_mec.bin for instance).

Also in the file radeon_cik.c there are MODULE_FIRMWARE
declarations/definitions that have both KAVERI_*.bin files and
kaveri_*.bin files. And the KAVERI_mec2.bin file was missing in that
list, in which all the files start with KAVERI (with capital letters).
Should this entry not be there? Although I tried it both ways. Adding
KAVERI_mec2.bin in the MODULE_FIRMWARE definitions. And tried it also
by removing that entry. It did not change anything.

I might have not put these files in the correct directory maybe. Am I
missing something?
