Bug ID: 85661 Summary: Double Firmware for Radeon GPUs (at least HAWAII) Product: Drivers Version: 2.5 Kernel Version: 3.17.0 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: debian@carbon-project.org CC: alexdeucher@gmail.com Regression: No
Not sure if this is a mistake or I'm missing something here, but I was looking at https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/radeon and noticed, that there are firmware files of the same name – except case – but different content for HAWAII and others, eg. HAWAII_ce.bin and hawaii_ce.bin: 7fa992d86295f741e8cdea76c5b6c632 linux-firmware/radeon/HAWAII_ce.bin 9e05820da42549ce9c89d147cf1f8e19 linux-firmware/radeon/hawaii_ce.bin For other firmware parts (eg. mc2) there is only one version available.
Now the question is: is this intended? Or should there only be one version? If I had to guess, I'd say the lower-case variants are the current ones, since they have the same checksums as the firmware I've downloaded from http://people.freedesktop.org/~agd5f/radeon_ucode/ in the course of https://bugs.freedesktop.org/show_bug.cgi?id=78453.
