[Bug 219888] amdgpu: Oops connecting HDMI/DVI/DP on HD 7850 (Pitcairn)
https://bugzilla.kernel.org/show_bug.cgi?id=219888 --- Comment #7 from Alexandre Demers (alexandre.f.dem...@gmail.com) --- DCE6's dce60_tg_funcs structure is missing .is_two_pixels_per_container = dce110_is_two_pixels_per_container It seems the fix is already in 6.14-rc7. -- You may reply to this email to add a comment.

https://bugzilla.kernel.org/show_bug.cgi?id=219888 --- Comment #6 from Alexandre Demers (alexandre.f.dem...@gmail.com) --- Looking at the commit, this bug probably affects a wider range of GPUs since DCE12.0 and DCE8.0 rely on the change applied to DCE11.0 -- You may reply to this email to add a comment.

https://bugzilla.kernel.org/show_bug.cgi?id=219888 --- Comment #4 from Alexandre Demers (alexandre.f.dem...@gmail.com) --- 6.12.0 was already "Oopsing". I hadn't checked if 6.11.0 was "oopsing" in the log though before testing 6.12.0, I'll have to check it out later. -- You may reply to this email to add a comment.

For precision, when I say "it freezes", I mean the GPUs freeze: no output on any of the GPUs. However, I still see activity on the front light of the computer, so the kernel itself is still running. If I connect the monitor on the RX 5500 XT in this configuration (sitting as secondary GPU) before booting, the RX 5500 XT works properly until I try to connect the monitor to the HD7850 (then, no output on any GPU after that).

https://bugzilla.kernel.org/show_bug.cgi?id=219888 --- Comment #2 from Alexandre Demers (alexandre.f.dem...@gmail.com) --- 6.11.0 exhibits the same problem where there is no output. There must a signal established though, since the monitor doesn't complain about "No signal". However, the boot process is stuck. Using the radeon driver works as expected. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.

https://bugzilla.kernel.org/show_bug.cgi?id=219888 --- Comment #1 from Alexandre Demers (alexandre.f.dem...@gmail.com) --- Since I had not encountered this problem until recently (the HD7850 was sitting as the primary GPU until my secondary GPU had to be replaced), I tried to inverse the primary GPU (RX 5500 XT) with the secondary GPU (HD7850). So, when the HD7850 sits as the primary GPU, it still doesn't output any video on 6.13.7 and it freezes. However, it works properly on 6.10.2 when sitting as primary (the HD7850 still doesn't output anything when sitting as the secondary GPU, but it doesn't crash. Thus, this seems be a different issue). I'll try to narrow it down a bit more to figure out if it was introduced between 6.10 and 6.13. -- You may reply to this email to add a comment.
