- **AMD SMI only reports 63 GPU devices when setting CPX on all 8 GPUs**
|
||||
When setting CPX as a partition mode, there is a DRM node limitation of 64.
|
||||
|
||||
This is a known limitation of the Linux kernel, not the driver. Other drivers, such as those using PCIe space (e.g., ast), may be occupying the necessary DRM nodes.
|
||||
|
||||
The number of DRM nodes used can be checked via `ls /sys/class/drm`

d. Confirm `amd-smi list` reports all nodes (this can vary per MI ASIC)

2) ***Update your OS' kernel***
|

Typically you can find examples online by searching "`Update kernel <your OS version> command line`"
|

|

Ex. "Update kernel Ubuntu 22.04 command line" should provide some good examples.

xf86drm: use drm device name to identify drm node type
|
||||
|
||||
Currently drm node's minor range is used to identify node's type.
|
||||
|
||||
Since kernel drm uses node type name and minor to generate drm
|
||||
|
||||
device name, It will be more general to use drm device name to
|
||||
|
||||
identify drm node type.
