 tuxiqae | Not sure, what's that | 16:18:58 |
 K900 | Firmware setting | 16:19:40 |
| K900 | Basically allows a much bigger DMA range for the GPU | 16:19:57 |
| K900 | -> faster transfers | 16:20:03 |
| tuxiqae | Don't think I ever did that | 16:20:20 |
| tuxiqae | Lemme check | 16:20:24 |
| K900 | Try lspci -vvv | 16:20:31 |
| K900 | And post the entry for your GPU | 16:20:41 |
| K900 | I don't remember where it shows memory mappings exactly so I can't tell you what to look for | 16:20:58 |
| K900 | But I'll know it when I see it | 16:21:03 |
| tuxiqae | Found that in the dmesg:
[drm] Detected VRAM RAM=20464M, BAR=256M
| 16:22:20 |
| K900 | Uhh check lspci | 16:22:40 |
| K900 | I'm not sure how late that is logged | 16:22:45 |
| K900 | Please just post the lspci snippet | 16:24:23 |
| K900 | Just to be sure | 16:24:26 |
| tuxiqae | Huh | 16:28:43 |

| 16:28:45 |
| tuxiqae | Why the heck is it using amdgpu | 16:29:19 |
| K900 | What else should it be using? | 16:30:01 |
| tuxiqae | Yeah, sorry about that, took me a moment to find out what package contains lspci haha | 16:30:05 |
| tuxiqae | radv, or so I thought | 16:30:18 |
| K900 | Anyway yeah definitely not enabled | 16:30:21 |
| K900 | In reply to @tuxiqae:matrix.org
radv, or so I thought RADV is the userspace driver | 16:30:29 |
| K900 | The kernel driver is called amdgpu | 16:30:34 |
| tuxiqae | Oh, I see | 16:30:38 |
| K900 | You need both | 16:30:39 |
| K900 | Anyway, go get to your firmware settings and enable resizable BAR | 16:30:53 |
| K900 | Should be somewhere in PCIe settings | 16:31:00 |
| tuxiqae | Lemme try, brb | 16:31:59 |
| tuxiqae | Damn, enabled Resizable BAR on my BIOS (super easily BTW)
Set the graphics to the highest settings and I now have about 250 FPS | 16:44:27 |
