W: Possible missing firmware /lib/firmware/i915/

hhh · 2017-03-24 12:50:54

This bug appeared in August on other OSes, I'm seeing it now when upgrading stretch. I know I can safely ignore it, since my hardware is working fine, but I'm thinking ahead to the stretch release and a flood of posts about this...

Should we create a post now that we can refer people to?

Booted into BL-upgraded-to-stretch and did the same gcc upgrades from today, no warning message. Does anyone know which firmware package is in BL that prevents this?

Are you saying then that there's a firmware package that we provide in BL... that's not in the debian stretch os? That may not be the case because:

This warning means that the driver references the firmware but that it isn't installed. Intel has not yet pushed out this firmware to upstream linux-firmware, once they have done so it will make it's way into Ubuntu. I'll also point out that we don't officially support any 4.8-based kernels yet, and when running early -rc kernels you're likely to hit some snags.

So unless something immediately changed, not sure why the same errors aren't show in our BL setup. Could it be specific to what apt sources you're using?

^ Broxton and Kabylake, that's the ticket... outstanding!

Thank you, sir. I'll mark this solved if I don't see warnings through several upgrades

Thanks!

So those drivers haven't entered upstream yet, I'm guessing.

Anyway, it's a warning, not an error.

The firmware will be added (or the kernel image patched) before the stable release, I'm sure.

Skylake hardware should work fine without the firmware blob but some advanced features will be unsupported.

It looks like the newer firmware is available now, though it probably isn't available in current Stretch release since the packages have been frozen. Life HoaSy said before it officially shifts to stable, it'll probably be important enough to stick in..

@HoaS Does firmware and more "comptability" type updates like this have an easier time for maintainers to allow into an already frozen distro release prior to going stable?

The firmware blobs are not part of the official release so maybe not, I don't know really though.

In the case of firmware, it is "safe" to install the .deb files meant for testing/unstable in the stable release (don't add the repositories though) and you can also download the firmware direct from the manufacturer yourself and drop it into /lib/firmware (this is what I do) but remember to keep track of it and update it when needed if you do this.

Hi....i am a new user here. As per my knowledge the firmware will be added before the stable release.Skylake hardware should work fine without the firmware blob but some advanced features will be unsupported.
