July 2023 - Linux-stable-mirror

by Limonciello, Mario

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!
