[Bug 200695] New: Blank screen on RX 580 with amdgpu.dc=1 enabled (no displays detected)

Xorg is not able to enable the display either. With amdgpu.dc=0 all is fine. Tried with various (mostly Debian) kernels from 4.16 through 4.18~rc4, all have the issue. I built a 4.18~rc7 from kernel.org to rule out Debian patches being the issue and will provide logs. -- You are receiving this mail because: You are watching the assignee of the bug.

Hey On request of Noralf, I picked up the patches and prepared v5. Works fine with Xorg, if configured according to: https://lists.freedesktop.org/archives/dri-devel/2014-January/052777.html If anyone knows how to make Xorg pick it up dynamically without such a static configuration, please let me know.

Product: Drivers Version: 2.5 Kernel Version: 4.18.10 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(a)kernel-bugs.osdl.org Reporter: rbrito(a)ime.usp.br Regression: No Dear developers, I have a notebook that is giving me a lot of trouble, especially as it is the newest computer that I have at my disposal where I can perform any actual work. This notebook has VERY frequent lockups (hard freezes, where the screen displays something where I am working, but the keyboard does not respond, the mouse doesn't either etc.). The only way that I can resume any work is by forcibly shutting it down (by pushing the power button for many seconds) and, of course, having all previous unsaved work lost (including a previous report of this bug with the bugzilla interface). :-( There is no particular pattern that I could discover so far that triggers the problem (for the past year, at least), but I do see some error messages on my dmesg logs and I would like start with some of the more salient points by sharing some problems that I have and, perhaps, zero in on potentially loose ends that may help everybody with hardware that is similar. The notebook in question is a Dell Inspiron 5548 with a Core i7-5500U, with two graphic cards (or so I am told), with one of them being integrated with the CPU and another being a discrete AMD GPU. The userspace that I am using is a Debian testing (soon to be Debian 10) with Debian's kernel 4.18.0-2-amd64 (which is actually a kernel 4.18.10-2). I can, of course, test any other kernels for the sake of getting things fixed. Just let me know and I will do my best to fix things. BTW, no kernel that I have ever used on this machine has every worked perfectly, even the prebuilt, unpatched kernels that Ubuntu compiles daily. With that being said, when the kernel boots up, there are some red messages on the dmesg log that are related to this AMD GPU (the entire dmesg log will be attached) with some prominent lines being: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - $ dmesg | grep -E -i "drm|amdgpu|i965" [ 13.054583] fb: switching to inteldrmfb from EFI VGA [ 13.059874] [drm] Replacing VGA console driver [ 13.060448] [drm] ACPI BIOS requests an excessive sleep of 10000 ms, using 1500 ms instead [ 13.061122] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

https://bugzilla.kernel.org/show_bug.cgi?id=199979 Bug ID: 199979 Summary: amdgpu: changing pwm1_enable from 1 to 2 does not resume automatic fan control Product: Drivers Version: 2.5 Kernel Version: 4.17.0 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(a)kernel-bugs.osdl.org Reporter: CWidmer(a)umbrox.de Regression: No When using the hardware monitoring interface to change pwm1_enable to 2 (automatic) from 1 (manual), the automatic fan control does not work as expected. Instead, the pwm1 value keeps jumping around between at least two values and a continuous, persisting, and unpleasantly high-pitched sound can be heard from inside the computer case. The only way to stop those things is writing some valid value to pwm1, which in turn also switches pwm1_enable back to 1. If the system is booted without ever manually changing the pwm1_enable value, which then defaults to 2, automatic fan control does work as intended. I am using a custom RX 580 (Sapphire Nitro+ Radeon RX 580 8GD5 Special Edition) on a Gentoo x86_64 system and was able to reproduce the issue with the 4.17.0 kernel with Gentoo patches, the Ubuntu kernel on the 18.04 image (should be a 4.15 one) and also with amd-staging-drm-next. -- You are receiving this mail because: You are watching the assignee of the bug.

[PATCH] drm: avoid spurious EBUSY due to nonblocking atomic modesets
by Daniel Vetter 23 Sep '20

23 Sep '20

When doing an atomic modeset with ALLOW_MODESET drivers are allowed to pull in arbitrary other resources, including CRTCs (e.g. when reconfiguring global resources). But in nonblocking mode userspace has then no idea this happened, which can lead to spurious EBUSY calls, both: - when that other CRTC is currently busy doing a page_flip the ALLOW_MODESET commit can fail with an EBUSY - on the other CRTC a normal atomic flip can fail with EBUSY because of the additional commit inserted by the kernel without userspace's knowledge For blocking commits this isn't a problem, because everyone else will just block until all the CRTC are reconfigured. Only thing userspace can notice is the dropped frames without any reason for why frames got dropped. Consensus is that we need new uapi to handle this properly, but no one has any idea what exactly the new uapi should look like. As a stop-gap plug this problem by demoting nonblocking commits which might cause issues by including CRTCs not in the original request to blocking commits. v2: Add comments and a WARN_ON to enforce this only when allowed - we don't want to silently convert page flips into blocking plane updates just because the driver is buggy.
