Hi,
A problem exists where dGPUs with type-C ports are considered power
supplies that power the system.
This leads to poor performance of the dGPU because graphics drivers like
amdgpu use power_supply_is_system_supplied() to decide how to configure
the dGPU.
This has been fixed in 6.5-rc1 by marking dGPUs as "DEVICE".
The logic to fix what to do when DEVICE is encountered was fixed in
6.4-rc4 and already backported to stable:
95339f40a8b6 ("power: supply: Fix logic checking if system is running
from battery")
So to wrap up the fix in stable kernels can you please backport:
6.4.y:
a7fbfd44c020 ("usb: typec: ucsi: Mark dGPUs as DEVICE scope")
6.1.y:
f510b0a3565b ("i2c: nvidia-gpu: Add ACPI property to align with
device-tree")
430b38764fbb ("i2c: nvidia-gpu: Remove ccgx,firmware-build property")
a7fbfd44c020 ("usb: typec: ucsi: Mark dGPUs as DEVICE scope")
Thanks!
