Summary
DeviceProperties is current through the CUDA 12.9/13.0 attribute additions, but the 13.1 and
13.3 attributes are missing:
| Attribute |
Version |
Note |
CU_DEVICE_ATTRIBUTE_ATOMIC_REDUCTION_SUPPORTED |
13.1 |
companion of #2361 |
CU_DEVICE_ATTRIBUTE_DMA_BUF_MMAP_SUPPORTED |
13.3 |
|
CU_DEVICE_ATTRIBUTE_D3D12_CIG_STREAMS_SUPPORTED |
13.3 |
|
CU_DEVICE_ATTRIBUTE_LOGICAL_ENDPOINT_UNICAST_SUPPORTED |
13.3 |
companion of #2358 |
CU_DEVICE_ATTRIBUTE_LOGICAL_ENDPOINT_MULTICAST_SUPPORTED |
13.3 |
companion of #2358 |
CU_DEVICE_ATTRIBUTE_LOGICAL_ENDPOINT_COUNTED_OPS_SUPPORTED |
13.3 |
companion of #2358 |
CU_DEVICE_ATTRIBUTE_LOGICAL_ENDPOINT_UNICAST_ACCESS_ON_OWNER_DEVICE_SUPPORTED |
13.3 |
companion of #2358 |
Proposed approach
Mechanical: add properties to DeviceProperties
(_device.pyx)
following the existing naming conventions, with the usual graceful handling on older
drivers/bindings; update the attribute coverage tests. Same shape as the (closed) #675 pass
for earlier toolkits. Doesn't need to wait for #2358/#2361 — the boolean queries are useful on
their own.
