re- kernel boot options: - i915.enable_psr=1 obviously (copy/pasted a previous grub kernel line) - flickering is present without any of the options mentioned above. (= standard fedora kernel defaults + i915.enable_psr=1). note: flickering also happens with kernel 4.0.6-300.fc22.x86_64 Confirmed, it happens for me aswell, when enabling PSR, using T450s on FHD IPS and uname -a Linux LAP1 4.0.7-2-ARCH #1 SMP PREEMPT Tue Jun 30 07:50:21 UTC 2015 x86_64 GNU/Linux cat /proc/cmdline BOOT_IMAGE=/vmlinuz-linux root=UUID=... rw quiet resume=/dev/sda3 i915.enable_ips=0 i915.enable_psr=1 (In reply to Johannes Schaub from comment #3) > Confirmed, it happens for me aswell, when enabling PSR, using T450s on FHD > IPS and uname -a > > Linux LAP1 4.0.7-2-ARCH #1 SMP PREEMPT Tue Jun 30 07:50:21 UTC 2015 x86_64 > GNU/Linux > > cat /proc/cmdline > > BOOT_IMAGE=/vmlinuz-linux root=UUID=... rw quiet resume=/dev/sda3 > i915.enable_ips=0 i915.enable_psr=1 Sorry, forgot to mention that I use archlinux.

1/2 - unmask LPSP patch
Created attachment 1049477 [details] 2/2 - increse idle frames Hi, First of all thanks for the report. could you please test both patches attached or test the following branch: http://cgit.freedesktop.org/~vivijim/drm-intel/?h=psr-to-ivan Thanks, Rodrigo. Hi Rodrigo, I compiled/tested the following kernels with your patches, but no luck: - 4.0.6-300.fc22.x86_64 (rebuilt src rpm with modified spec file with your patches): flickering is still present - 4.1.0+ (git clone the psr-to-ivan branch) with fedora's 4.0.6's .config. : the screen goes blank just after modeset during boot. The system is not hard frozen (ctrl-alt-del reboots the laptop) but there's no activity and nothing in the logs. I remember having hard lockups with i915.semaphores=1, so I tried with semaphores=0, as well as enable_ips=0, but it didn't help. - 4.2-rc1: hard freeze at early boot with "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE) ! " msg. Maybe Johannes above will have more luck. Thanks, Ivan Hi Ivan, Thanks for the attempts. Could you please try another branch? It is just "psr": http://cgit.freedesktop.org/~vivijim/drm-intel/log/?h=psr Also, on psr-to-ivan, what happens if you boot with i915.enable_psr=0? is it still blank or does it work? Please on this new "psr" branch please also boot with and without i915.enable_psr=0. Also, on this blank screen do you still have ssh access? what does i915_edp_psr_status on debugfs tell you? Regarding semaphores it is disabled by default on BDW anyway. Thanks, Rodrigo. note: Rodrigo is working on the issue but our email exchange is a bit lengthy for bugzilla so I'll follow up here when we make progress Ivan, is it still useful to build against that psr branch and submit reports on this flicker/screen-blank issue or is it better to wait on report from you and Rodrigo? -Ethan Hi Ethan,
Rodrigo created a new test branch ("psr-delayed-enable") but there are still problems, so it's better to wait. You may want to check the following bug, this is where I test Rodrigo's stuff:

(I didn't put this url as an external bug since the problem is not flickering anymore)
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. This same issue is happening on Fedora 35 on my Lenovo Ideapad 7i with an i7-11370H processor with the Iris Xe graphics. Adding i915.enable_psr=0 as stated masks the issue as before. No other kernel options other than normal defaults are set.
Current kernel is 5.15.17-200.fc35.x86_64 (it has happened on every kernel since install)

I should note, I am running the KDE spin, in case that makes a difference. Also using Wayland since it is now default.
What information or testing can I provide to help troubleshoot/fix the issue?

Hi Ron Please take a look at https://gitlab.freedesktop.org/drm/intel/-/issues. There is a couple of PSR bugs under debug, please check if your issue matches one of those. If not please file a new bug following: https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs In addition to the instructions above, please add i915.psr_safest_params=1 to your kernel parameters and let us know if it helps or not. |

And when it does, the following drm debug message shows up: [drm:drm_atomic_set_fb_for_plane] Set [FB:54] for plane state ffff88032a869540 I tried to enable/disable power saving features as was suggested somewhere else, tried to set drm.atomic=1 (since the debug msg had something to do with atomic), and quite a few other combinations (kernel options, ...), but still no luck.
