[Kernel-packages] [Bug 1633690] Re: byt-max98090 not working on linux-image-4.8.0-22-generic on baytrail hardware
There are a couple of issues: first the byt-max98090 is not enabled by default due to conflict with other sound codecs (see: https://lkml.org/lkml/2016/8/11/741) The driver configuration is such that SND_SST_IPC_API needs to be disabled for SND_SOC_INTEL_BYT_MAX98090_MACH to be selectable. To disable SND_SST_IPC_API all other drivers dependant on it have to be disabled as well. This means on distribution can only support either a baytrail max98090 or all other sound codecs at the moment (need to wait for upstream resolution). The second issue is the codec cannot be probed unless gpio can use CRS (see https://github.com/GalliumOS/linux/commit/cee2747204b11b63042777dd01fe336e9b49fef0 #diff-32b258ffa70fb36e4c510fca532f6d23R21 ) In the mean time while the issue is worked on by upstream, you can build your own kernel with the attached patches. See https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel This is how I built it on my machine: git clone git://kernel.ubuntu.com/ubuntu/ubuntu-yakkety.git --depth 1 git am bytmax98090-kernel-patches/*.patch fakeroot debian/rules clean DEB_BUILD_OPTIONS=parallel=8 fakeroot debian/rules binary-generic Also note you still need to have the asound.state from chromeOS which you can get at: https://github.com/GalliumOS/galliumos- baytrail/blob/master/var/lib/alsa/asound.state You can also use my ppa at your own risk :) at: https://launchpad.net/~albaguirre/+archive/ubuntu/linux-bytmax98090/ I use this ppa to get sound on an Acer CB3-111 (GNAWTY), booting with BOOT_STUB firmware from MrChromebox (https://mrchromebox.tech/#fwscript) ** Attachment added: "bytmax98090-kernel-patches.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1633690/+attachment/4785638/+files/bytmax98090-kernel-patches.tar.gz -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1633690 Title: byt-max98090 not working on linux-image-4.8.0-22-generic on baytrail hardware Status in linux package in Ubuntu: Confirmed Bug description: After a recent 'do-release-upgrade' upgrade from Xenial's linux- image-4.4.0-42-generic kernel to Yakkety's linux- image-4.8.0-22-generic, I lost my audio output.

On a hunch I installed linux-image-4.7.2-galliumos from the galliumos repo and got my sound working again, which to me confirms that this is a kernel issue and not a userland issue.

(In reply to comment #17) (In reply to comment #0) Any sequence that turns off/on the panel (suspend/resume, modesetting) results in a blank screen. Wait.

[Kernel-packages] [Bug 1265544]
Daniel, I'm already running drm-intel-nightly which includes that commit. That particular hack does indeed run (see attached dmesg log at the beginning) but the panel is still blank. I saw the same hack at intel_dp_get_config, but in my machine intel_dp_get_config does not get called at all. The culprit is clamping bpp from 24 to 18 bpp at intel_dp_compute_config. When the bpp clamping code is disabled and the panel runs at 24 bpp there are no more blank screen issues.

[Kernel-packages] [Bug 1265544] Re: 8086:0a16 [UX302LG] black screen on boot 3.12.0-7
I debugged a bit further on the waking from sleep issue - it actually also happens when changing modes through xrandr so not really related to waking from S3, just turning off/on the display. The display in the UX302LG/LA needs to be run at 24-bit apparently - the current intel-gfx code (including in drm-intel-nightly) is clamping to 18bpp due to the BIOS advertising such info in the VBT (the same behavior is seen with CSM and nonCSM mode). If you remove the clamping, then everything works (display up at boot, modesetting works, waking from sleep works) - you don't really need commit c26fe8e5eb34c18aa9ab60fcf4c3150663a52306 BTW, just removing the clamping to run the pipe at 24bpp fixes all the blank screen issues. This behavior was noted on other laptops as described in the intel-gfx bug: https://bugzilla.kernel.org/show_bug.cgi?id=59841 As you can see in the bug description above, the temporary solution that's been merged in 3.12 was this hack: https://bugzilla.kernel.org/attachment.cgi?id=111321action=diff Not entirely sure why that is not working for the UX302LG/LA yet (in fact I don't see dp_get_config called at all for some reason, so the hack does not go into effect). ** Bug watch added: Linux Kernel Bug Tracker #59841 http://bugzilla.kernel.org/show_bug.cgi?id=59841 ** Patch added: 0001-i915-Ignore-eDP-clamping-to-BIOS-provided-VBT-value.patch https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1265544/+attachment/3946655/+files/0001-i915-Ignore-eDP-clamping-to-BIOS-provided-VBT-value.patch -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1265544 Title: 8086:0a16 [UX302LG] black screen on boot 3.12.0-7 Status in “linux” package in Ubuntu: In Progress Bug description: Same description/workaround as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1263015 I tried both Enable CSM and non-CSM boot.

[Kernel-packages] [Bug 1265544] Re: 8086:0a16 [UX302LG] black screen on boot 3.12.0-7
I have an ASUS UX302LA which is essentially the same as the UX302LG except without the NVIDIA gpu that exhibits the same issue - blank screen on boot. I cherry-picked the commit dff392dbd258381a6c3164f38420593f2d291e3b (same patch as c26fe8e5eb34c18aa9ab60fcf4c3150663a52306) from ~danvet /drm-intel (see http://cgit.freedesktop.org/~danvet/drm- intel/commit/?id=dff392dbd258381a6c3164f38420593f2d291e3b ) on top of tag Ubuntu-3.13.0-1.16 in git://kernel.ubuntu.com/ubuntu/ubuntu- trusty.git and rebuilt the i915 kernel module - which fixes the blank screen issue at boot; the issue of blank screen after resuming from sleep is indeed still there after this patch. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1265544 Title: 8086:0a16 [UX302LG] black screen on boot 3.12.0-7 Status in “linux” package in Ubuntu: In Progress Bug description: Same description/workaround as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1263015 I tried both Enable CSM and non-CSM boot.
