At first I didn't understand. It asked for a file, and I gave it that file, but it still errored out. Then things got curiouser and curiouser. Webpage https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915 lists kbl_dmc_ver1_04.bin as being 8840 bytes... ***BUT*** the downloaded file on my system is 62768 bytes!!! Houston... we have a problem. I dove into my download with mc, and it's actually a webpage with some binary listing! No wonder it didn't work. I tried different websites and got a 62768 byte file. I switched from Pale Moon (a Firefox fork) to Google Chrome for linux... 62768 bytes. Even wget got me a 62768 byte file. What's going on??? > PS.

Can you email it to me off-list as an attachment? That 8840 byte size is what I'm looking for. BTW, there is a thread... https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/9244 about problems with that firmware. -- Roses are red Roses are blue Depending on their velocity Relative to you
