@ashaferian, if you haven't seen it, this looks like a helpful resource for what you're investigating: https://www.kernel.org/doc/html/v4.15/gpu/drm-mm.html I'm not too familiar with drm_vma_node_start(), but hopefully the above document helps.

@ashaferian, nice debugging. I stepped through things on the EGL side on Linux, and it looks like there is a good chunk of the code that interfaces EGL and DRM...

G-Sync is expected to work with the open kernel modules as of 535.43.02, at least on desktop GPUs. We still have some loose ends to address for notebook; G-Sync on...

Thanks, we're aware of the limitation in nvidia-powerd; that should be addressed in an upcoming release.

Sorry, I don't know off hand why the support is limited to those chipsets, but I'll try to find out.

Could I trouble you to retest with 535.43.02? The release highlights call out: ``` * Extended Dynamic Boost support on notebooks to include older Renoir and Cezanne chipsets, in addition...

Thanks. We're aware of the issue, and a fix should be in a release shortly. You can refer to this as NVIDIA internal bug 4854525.

To help better isolate this, looking more carefully at your xorg.conf: Option "nvidiaXineramaInfoOrder" "DFP-3" Option "metamodes" "DP-2: 2560x1440_165 +0+0 {ForceFullCompositionPipeline=On}, DP-0: 2560x1440_165 +2560+0 {ForceFullCompositionPipeline=On}" Option "UseNvKmsCompositionPipeline" "false" Do you see...
