Missing PCI IDs for Intel 7265D wireless hw

[Timo Aaltonen]

== SRU Justification ==

Impact: Some Intel 7265D wireless hardware doesn't work because the PCI ids are missing in iwlwifi.

Fix: Upstream commit to add in the missing ids.

Regression Potential: Fix only adds new PCI ids so regressions are very unlikely.

---

My Intel SDP has a version of the hw that needs at least "iwlwifi-7265D-17.ucode", though I'm not sure where to get that, since upstream repo doesn't have it.

You should be able to find it here:

https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/

Intel doesn't send every version of their firmware to upstream linux-firmware, only ones they've decided are stable enough. So in general we just stick to those versions, but it looks like there's not an option for this hardware. If you find your firmware there and find that it works I think we can go ahead and add it to Ubuntu's linux-firmware.

[Seth Forshee (sforshee)]

So it looks like we already have a -13 ucode for your hardware already in trusty onward, and from looking at the code it looks like even the tip of the upstream kernel should still work with that version. Is it not working?

[Timo Aaltonen (tjaalton)]

well, looks like it'll try several ones but none are found :)

this is while using 4.3-rc7. 4.2 doesn't init the device at all.

This last line indicates that it loaded the -13 firmware. The driver
supports a range of firmware versions. It starts trying to load the
newest and works its way back, that's why you see all the failed load
attempts.

Does the device work properly after this?

Can you provide dmesg for 4.2 and the pci ids for the device?

[Timo Aaltonen (tjaalton)]

it's 8086:095a, grepping for 'iwlwifi' gives no hits with 4.2 or even 4.3-rc6, and the reason is that it needs f08f625876476b6c4a87834dc86e3b927f4697d2 from 4.3-rc7.

[Timo Aaltonen (tjaalton)]

that commit is cc: stable btw, so it'll get in 4.2 eventually.

[Seth Forshee (sforshee)]

That's what I was starting to suspect, that it was the PCI ids missing an not the firmware. It shouldn't be a problem to pick that patch up early since all it does is add PCI ids.

[Seth Forshee (sforshee)]

I've cherry picked the commit you identified onto 4.2. Please test the build at the following link and verify that your wireless work.

[Timo Aaltonen (tjaalton)]

Yep, seems to work fine, thanks.
