https://bugzilla.kernel.org/show_bug.cgi?id=216376 Bug ID: 216376 Summary: AMDGPU: display output disables and quickly reenables when switching AVR into/from standby doing HDMI passthrough Product: Drivers Version: 2.5 Kernel Version: 5.19.1 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: jlp.bugs@xxxxxxxxx Regression: No Created attachment 301600 --> https://bugzilla.kernel.org/attachment.cgi?id=301600&action=edit dmesg I have A PC with Radeon RX480 which has HDMI output connected to HDMI input on Marantz SR5015 AV reciever and there the HDMI output goes to a TV (Panasonic TX-55CX200E). The DVI output is connected to an LCD monitor. The AVR has the feature to pass through HDMI signal when put into standby mode. When I switch AVR from/to standby mode it looks like it for a very short time interrupts the connection from PC to TV and during this time it appears that the video card output turns off and monitor layout is re-aranged to one screen (DVI) only and then almost immediately back two previous dual screen layout. Would it be possible to delay turning off the HDMI output for a bit longer so that it would wait long enough that AVR would reconnect entire HDMI path to TV back again and the HDMI output on video card would not need to be turned off and keep sending output in the meantime? So that the display layout configuration would keep being in dual-screen mode for the whole time? -- You may reply to this email to add a comment.
