Partition Mode Support

Number of VFs per GPU	Dynamic Compute Partitioning	NPS1	NPS2	NPS4
1	SPX (Default)	MI300X, MI325X, MI35XX
1	DPX		MI35XX
1	CPX		MI35XX (Preview)
8*	CPX			MI300X (Preview)

For the full list of supported partition modes and the relationship between partition mode and number of VFs per GPU, see the GPU Partitioning.

* Multi-VF (8 VF) Support requires a compatible firmware BKC bundle for the GPU.
Please refer to the ROCm Firmware Compatibility Table for the list of required firmware versions and supported configurations.

---

Host AMD SMI Versions

• Library: 50.2.2
• Tool: 32.4.1

Please checkout out SMI doc for more details.

---

Getting Started

Please check out our User Guide for instructions on how to set up GIM and example configurations to run SR-IOV enabled VMs.

---

Known Issues

1. When using the configuration of 64 ROCM devices in 1 VM (aka CPX mode with 1 VF) on a MI350 platform, we would see a hang in workloads which use SDMA engines
2. MultiVF configuration for MI300X requires specific firmware version. please refer to the ROCm compatibility matrix for supported version
3. MI210: Unloading the Guest driver on MI210 may produce kernel call trace. Note that this is just a warning and not a kernel panic. Guest VM reboot is required to restore the operation ​
4. SMI CLI topology --link_type command returns wrong value for the first BDF​
5. SMI CLI static --vram command returns 0 for the bit width value​
6. Some BDF values returned from SMI get_link_topology_nearest APIs are wrong

Known Issues

With NPS1/SPX and 8VMs (1VF per VM) on MI300, triggering reset via "/sys/kernel/debug/kfd/hang_hws" causes the GPU to become unusable. Rebooting the guest should solve the problem.
