As the Geminilake firmware is now merged to linux-firmware.git use MODUE_FIRMWARE to load the firmware.
This removes the error message in the dmesg log:
i915 0000:00:02.0: Direct firmware load for i915/glk_dmc_ver1_04.bin failed with error -2 i915 0000:00:02.0: Failed to load DMC firmware i915/glk_dmc_ver1_04.bin. Disabling runtime power management. i915 0000:00:02.0: DMC firmware homepage: https://01.org/linuxgraphics/downloads/firmware
and now shows that the firmware has correctly loaded:

I included 'Cc: stable' so the patch would get added to the v4.16 and v4.15 kernels which I have tested with the patch. I found that earlier kernels didn't support the 'linux-firmware' package required to get wifi working on Intel's new Gemini Lake NUC.
PS. How is this a "RESEND"? I haven't seen this before.
It is a 'RESEND' for that very reason. I initially sent the patch to the same people as a similar patch (https://patchwork.kernel.org/patch/10143637/) however after realising this omitted required addresses I added them and resent the patch.

Yes. Runtime power management depends on the patch but when distros such as Ubuntu are installed on a Intel Gemini Lake NUC as an example, wifi/bluetooth depends on Intel Wireless-AC 9462 which in turn depends on v4.15 as a minimum so my logic was to add the patch to 4.15 and later.

And even then, some distros will be surprised of the new MODULE_FIRMWARE and will need to update the linux-firmware package, too.
I've performed backport testing and some additional analysis as follows:
The DMC firmware for GLK was initially included in 4.11 (commit: dbb28b5c3d3cb945a63030fab8d3894cf335ce19). Then the firmware version was upgraded to 1.03 in 4.12 (commit: f4a791819ed00a749a90387aa139706a507aa690). However MODULE_FIRMWARE for the GLK DMC firmware was also removed in 4.12 (commit: d9321a03efcda867b3a8c6327e01808516f0acd7) together with the firmware version being bumped to 1.04 (commit: aebfd1d37194e00d4c417e7be97efeb736cd9c04).
The patch below effectively reverts commit d9321a03 because the GLK firmware is now available in the linux-firmware repository.
To test stable backports I've used Ubuntu 18.04 (Beta 2) userspace with both Ubuntu (generic) and self-compiled mainline (patched) kernels. The conclusion was that the patch works across 4.12 to 4.17-rc1 kernels additionally displaying a 'Possible missing firmware' message when installing a kernel with the expected firmware missing.
The following are abridged backport test results:
Scenario: No DMC (glk_dmc_ver1_04.bin) firmware installed in '/lib/firmware/i915' Test:Kernel installation ('grep -i dmc' output from 'apt install'): 4.12-generic and 4.15-generic: No output # as expected 4.12 to 4.17-rc1-patched: W: Possible missing firmware /lib/firmware/i915/glk_dmc_ver1_04.bin for module i915 Result: The effect of the patch is to add a 'Possible missing firmware' message.

I did some basic testing including running a 4K video on Chrome whilst running intel_gpu_top. The intel_gpu_top program doesn't display anything on 4.12 either with or without the patch as neither I nor Canonical enabled CONFIG_DRM_I915_ALPHA_SUPPORT. Do you think that the stable tag should exclude 4.12 because of the 'alpha quality support' and if so do you want a V2 of the patch?

I understand your concerns, but the problem was that our old process was a bit (lot?) messed and there was the unreliable time until the firmware really lands on linux-firmware.git. So MODULE_FIRMWARE call was only added after firmware was really there on firmware repository but it wasn't about the testing.
In other words, the bump version patch was merged after tested, but MODULE_FIRMWARE was left behind because firmware blob took a while to get pulled into linux-firmware.git and we end up forgetting to add it there.
In my opinion it should be safe to add the MODULE_FIRMWARE there based on the tests from when the version was bumped.

Hi all:
We tested GLK DMC 1.04 FW in last week of September 2017, using the latest drm-tip version for that time (4.14.0-rc2) and according to our results we could declare this FW as acceptable and healthy to be used with kernel version 4.14 . However, we cannot guarantee quality and healthy of this FW if it is used in top of current drm-tip kernel (4.17-rc0).

NAK on indiscriminate Cc: stable. There are zero guarantees that older kernels will work with whatever firmware you throw at them.
I included 'Cc: stable' so the patch would get added to the v4.16 and v4.15 kernels which I have tested with the patch. I found that earlier kernels didn't support the 'linux-firmware' package required to get wifi working on Intel's new Gemini Lake NUC.
You realize that this patch should have nothing to do with wifi?
Rodrigo, Anusha, if you think Cc: stable is appropriate, please indicate the specific versions of stable it is appropriate for.
Hi Jani,
The stable kernel version is 4.12 and beyond. It is appropriate to add the CC: stable in my opinion
Who tested the firmware with v4.12 and later? We only have the CI results against *current* drm-tip. We don't even know about v4.16.
I understand your concerns, but the problem was that our old process was a bit (lot?) messed and there was the unreliable time until the firmware really lands on linux-firmware.git. So MODULE_FIRMWARE call was only added after firmware was really there on firmware repository but it wasn't about the testing.
In other words, the bump version patch was merged after tested, but MODULE_FIRMWARE was left behind because firmware blob took a while to get pulled into linux-firmware.git and we end up forgetting to add it there.
In my opinion it should be safe to add the MODULE_FIRMWARE there based on the tests from when the version was bumped.
Luis, Elio, can you guys confirm that this firmware is tested and healthy? And also, give a tested-by to this patch please?
Thanks, Anusha
I'm not going to ack and take responsibility for the stable backports unless someone actually comes forward with credible Tested-bys.
BR, Jani.
Anusha
BR, Jani.
PS. How is this a "RESEND"? I haven't seen this before.
It is a 'RESEND' for that very reason. I initially sent the patch to the same people as a similar patch (https://patchwork.kernel.org/patch/10143637/) however after realising this omitted required addresses I added them and resent the
patch.

Hi all:
We tested GLK DMC 1.04 FW in last week of September 2017, using the latest drm-tip version for that time (4.14.0-rc2) and according to our results we could declare this FW as acceptable and healthy to be used with kernel version 4.14 . However, we cannot guarantee quality and healthy of this FW if it is used in top of current drm-tip kernel (4.17-rc0).

Your measured response is appreciated and raises at least four possible alternatives for this patch to proceed:
1. It is normal that firmware is *only* tested at a certain point in time with the drm-tip version of the mainline kernel so that the statement 'firmware X is acceptable and healthy to be used with kernel version Y but is not guaranteed with Y+1 or Y+n' always holds true for any microarchitecture codename's DMC firmware. Therefore it is appropriate for this patch to have a restricted 'Cc: stable@vger.kernel.org # 4.14' tag together with an explicit 'Tested-by: (in 4.14)' tag. 2. As firmware testing was not performed on 4.15 and subsequent versions, testing is still required on versions 4.15 through to the current RC of version 4.17 for the patch to receive a 'Tested-by:' tag together with a 'Cc: stable@vger.kernel.org # 4.14' tag. 3. Further firmware testing will only be undertaken for the current RC of version 4.17 and on successful completion the patch will only receive a 'Tested-by:' tag. A 'Cc: stable@vger.kernel.org' tag is not applicable. 4. The firmware was not tested on 4.15 and subsequent versions as it's functionality was provided by alternative means and therefore the patch is only required in version 4.14 and should have a 'Cc: stable@vger.kernel.org # 4.14 only' tag together with a restricted 'Tested-by: (only in 4.14)' tag.
Could you indicate which alternative is appropriate? If further firmware testing is required (as in points 2 or 3) then can an expected completion date be provided?
Best regards, Ian
Hi Anusha,
Can I ask if this is on anyone's radar as I'm concerned this patch will stall otherwise?
I see that the significance of testing with the 4.14 kernel enabled the firmware to be included in the latest Chrome OS kernel ( https://groups.google.com/a/chromium.org/forum/#%21topic/chromium-os-reviews...). It is important to similarly include in the mainline and stable kernels to facilitate various distros that are now raising bug reports (for example: https://bugs.launchpad.net/intel/+bug/1760545).
Many thanks, Ian On Sun, 22 Apr 2018 at 08:46, Ian W MORRISON ianwmorrison@gmail.com wrote:

Pushed to drm-intel-next-queued, thanks for the patch.
I opted to drop the Cc: stable for now. This doesn't mean it can't be backported later on, I'm just punting on that call right now to make some forward progress here.
Joonas, please do pick f6d3e06f0747 ("drm/i915/glk: Add MODULE_FIRMWARE for Geminilake") to drm-intel-fixes to queue it to v4.17.
BR, Jani.

Done. That's the only drm-intel-fixes patch there seems to be for -rc4.
