While using [*] accidentaly works for html, it fails for other document outputs. In particular, it causes an error with LaTeX output, causing all books after networking to not be built.

Currently, the only way to disable the pin shutup is to hard-code spec->shutup = alc_no_shutup; in the fixup, and this makes the debugging harder for normal users. For allowing users to test the similar effect without recompiling the kernel, this patch adds a new hint string "shutup". It's a boolean value, and by passing false to this, user can turn off the pin shutup call. For example, to turn off the shutup on Lenovo P50, create a "firmware patch" file (e.g. /lib/firmware/alsa/lenovo-p50) containing the following lines: [codec] 0x10ec0298 0x17aa222e 0 [hint] shutup = no and pass the file via patch option of snd-hda-intel module (e.g. patch=alsa/lenovo-p50).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 33193dca671c ("ALSA: usb-audio: Add a quirk for Nura's first gen headset") added a quirk for Nura headset with USB ID 0a12:1243, with a hope that it doesn't conflict with others. Unfortunately, other devices (e.g. Philips Wecall) with the very same ID got broken by this change, spewing an error like: usb 2-1.8.2: 2:1: cannot set freq 48000 to ep 0x3 Until we find a proper solution, fix the regression at first by disabling the added quirk entry.

Currently, atomic_commit() does not handle bo operations for cursor plane, as a result the bo assigned for cursor plane in dm_plane_helper_prepare_fb() is not coherent with the updates to the same made in dc code.This mismatch leads to "bo" corruption and hence crashes during S3 entry. This patch cleans up the code which was added as a hack for 4.9 version only.

| | * | | drm/amdgpu: Grab/put runtime PM references in atomic_commit_tail()Lyude Paul2018-06-131-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So, unfortunately I recently made the discovery that in the upstream kernel, the only reason that amdgpu is not currently suffering from issues with runtime PM putting the GPU into suspend while it's driving displays is due to the fact that on most prime systems, we have sound devices associated with the GPU that hold their own runtime PM ref for the GPU. What this means however, is that in the event that there isn't any kind of sound device active (which can easily be reproduced by building a kernel with sound drivers disabled), the GPU will fall asleep even when there's displays active. This appears to be in part due to the fact that amdgpu has not actually ever relied on it's rpm_idle() function to be the only thing keeping it running, and normally grabs it's own power references whenever there are displays active (as can be seen with the original pre-DC codepath in amdgpu_display_crtc_set_config() in amdgpu_display.c). This means it's very likely that this bug was introduced during the switch over the DC. So to fix this, we start grabbing runtime PM references every time we enable a previously disabled CRTC in atomic_commit_tail(). This appears to be the correct solution, as it matches up with what i915 does in i915/intel_runtime_pm.c. The one sideaffect of this is that we ignore the variable that the pre-DC code used to use for tracking when it needed runtime PM refs, adev->have_disp_power_ref. This is mainly because there's no way for a driver to tell whether or not all of it's CRTCs are enabled or disabled when we've begun committing an atomic state, as there may be CRTC commits happening in parallel that aren't contained within the atomic state being committed. So, it's safer to just get/put a reference for each CRTC being enabled or disabled in the new atomic state.
