Add support for AMD GTT Memory
Can you please add a bar to nvtop to show GTT Memory usage (beside VRAM) on AMD GPUs?
Upvote this request. I'm using AMD integrated iGpu with only 512 MiB VRAM and 50 GiB GTT ram. Need to use amdgpu_top for it. Wait for it a lot.
This info is pretty trivial to query from libdrm, but adding a new memory progress bar on the same line makes them way too narrow. I'm not much of a UI person and some ideas I prototyped didn't look very good. Any ideas on how the UI can be refactored to accommodate another memory bar? @Syllo
It would be nice if we can move the memory progress bars to a new line below, as the encoder/decoder display logic is already quite messy.
Existing layout:
Device 0 [AMD Radeon Graphics] Integrated GPU RX: N/A TX: N/A
GPU 1900MHz MEM 1000MHz TEMP 36°C CPU-FAN POW 4 W
GPU[ 0%] MEM[ 0.014Gi/8.000Gi]
Device 0 [AMD Radeon Graphics] Integrated GPU RX: N/A TX: N/A
GPU 1900MHz MEM 1000MHz TEMP 36°C CPU-FAN POW 4 W
GPU[ 0%] MEM[ 0.014Gi/8.000Gi] ENC[ 0%] DEC[ 0%]

As a potential solution without needing to change the UI - how about if you just add VRAM + GTT and show that?

I've opened a PR that does just that. Works well for me.
I just want to mention, that will work well for iGPUs, because it doesn't matter there, it's the same physical RAM.
For dGPUs, they are different, and seeing this would be useful to debug performance issues when games are GTT'd out.
Yeah; that's why I set the change to only apply on APU. Existing policy to only show VRAM is for dGPU.
