00:38 sgm: Hi. I'm thinking about upgrade from Navi2 to Navi3. I did read about issues here and there with new (now current) generation of AMD GPUs. Was it because of early days/adoption and development of amdgpu driver for Navi3, or this gen compared to Navi2 is having problems you would not recommend an upgrade?
18:41 debianusr81: I installed a brand new AMD graphics card into my PC (previously NVIDIA). Debian Linux 12. I even made a total fresh install, and followed the recommendations and instructions in the Debian manual. I used the open/default drivers and installed that "contrib" (nonfree) firmware-amd-graphics package, which it specifically tells you to do to avoid bad performance. In spite of all this, I still have horrible performance, only slightly better
18:41 debianusr81: than the NVIDIA nightmare. For example, selecting a rectangle on the KDE Plasma 5 desktop LAGS noticeably, just like Windows XP did in the year 2001 for me, and which really annoyed me. But in KDE Plasma, you can't even turn that transparent rectangle thing off; it's forced on you. What could be wrong?
18:42 debianusr81: Using X11, but also tried Wayland it was the same.
18:43 debianusr81: I've asked others and they claim that the selection rectangle on Plasma's desktop is supposed to perfectly/instantly follow the cursor.
19:15 Remco: debianusr81: The output of `glxinfo -B` and the drm parts in dmesg would help
19:15 debianusr81: Says command not found for glxinfo?
19:16 Venemo: debianusr81: you forgot to mention which GPU you got
19:17 dwfreed: install glxinfo...
19:17 dwfreed: look like the debian package is mesa-utils
19:17 debianusr81: While trying to get the dmesg data requested, I noticed tons of this (not sure if this is about the graphics card or something else):
19:17 debianusr81: [44055.729605] pcieport 0000:00:01.0: AER: Multiple Corrected error received: 0000:01:00.0
19:17 debianusr81: [44055.729650] pcieport 0000:01:00.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver ID)
19:17 debianusr81: [44055.729657] pcieport 0000:01:00.0: device [1002:1478] error status/mask=00000080/00002000
19:17 debianusr81: [44055.729665] pcieport 0000:01:00.0: [ 7] BadDLLP
19:18 debianusr81: Venemo: "MSI Radeon RX 6400 4GB AERO ITX"
19:18 debianusr81: dwfreed: Installing...
19:18 dwfreed: that suggests you might need to reseat the graphics card because it's got a bad connection
19:19 Venemo: does 'lspci' recognize your GPU?
19:19 Venemo: either way it sounds like either a HW defect, or bad connection
19:19 debianusr81: Venemo: Seemingly: "03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 24 [Radeon RX 6400/6500 XT/6500M] (rev c7)"
19:19 Venemo: okay, what does vulkaninfo say?
19:20 debianusr81: It could very well be bad connection, but I really did my very best and even used compressed air first to get rid of any dust etc.
19:20 Venemo: and/or glxinfo
19:20 Venemo: and please use a pastebin site and don't paste it into this channel
19:21 Remco: (vulkaninfo is in vulkan-tools, for after you've put the glxinfo output on a pastebin)
19:21 debianusr81: Output of `glxinfo -B`: https://pastebin.com/raw/RwsMhWZw
19:24 debianusr81: And the massive vulkaninfo output: https://pastebin.com/raw/g6zRpCsw
20:02 debianusr81: ping
20:02 debianusr81: Just worried that I'm disconnected.
20:06 dwfreed: You're still here
20:14 Venemo: interesting
20:16 Venemo: well it looks like the system recognizes your card
20:16 Venemo: can you also do a paste of a dmesg?
20:28 debianusr81: Venemo: The entire dmesg output is literally just repeated those four lines I pasted above.
20:30 Venemo: sounds like that is your problem
20:31 Venemo: do you use a riser cable or any kind of PCIe extender?
20:32 Venemo: those things can be finnicky, and may be responsible for issues like this
20:32 Venemo: otherwise, I recommend to plug out the card and plug it back in, and/or lower the PCIe link speed in your BIOS to see if that helps
20:58 debianusr81: Venemo: No, directly connected to the wide PCI Express slot.
20:59 debianusr81: It surprises me a lot that it can work *at all* if not properly inserted.
21:00 debianusr81: I will definitely open the machine up again and "re-seat" the graphics card.
21:03 HdkR: A spam of corrected PCIe link issues in dmesg is spooky
21:11 debianusr81: :/
