[HIP][MI100] Virtual Memory Management API on MI100? #3151
Comments
Which OS are you running? For Ubuntu 20.04, you need the HWE stack. I'm not sure about other distros. |
Yup Ubuntu 20.04. Thanks, that makes sense - I'll try switching the kernel. |
Switched to the HWE stack and reinstalled, but it's still coming back as not supported. Here's my kernel and package versions:

I do not see here something HIP RT-related: case hipDeviceAttributeVirtualMemoryManagementSupported:
*pi = static_cast<int>(g_devices[device]->devices()[0]->info().virtualMemoryManagement_);
break; Looks like HW or HSA RT specifics. @gargrahul, could you please have a look too? |
Hey @gargrahul and @emankov, can we check back on this? Possible for us to get more info on your roadmap here / when it might be available? Email is fine, thanks. cc: @crozhon |
@gargrahul, @mangupta could you please let us know to whom we should address this ticket? We suspect HSA RT/HW. Thank you in advance! |
@crozhon : The ROCm driver does not support Virtual Memory Management and hence HIP runtime reports |
@crozhon We have an internal ticket to add support in future ROCm release. Will provide ROCm release info when available. Thanks! |
Does MI100 support the virtual memory management API? (functions hipMemAddressReserve, hipMemMap). I've been following this test case (https://github.com/ROCm-Developer-Tools/hip-tests/blob/094b9af382585a079d13c735fd170e69bea735b6/catch/unit/memory/hipMemVmm.cc), and virtual memory is always unsupported on all of our devices.
I've attached a small test program that queries for support and it always returns 0/false on rocm-5.4.2.
hipDeviceAttributeVirtualMemoryManagementSupported : 0
Is there something wrong with my setup or are these APIs just not supported on these devices?
