I am trying to understand how to take advantage of the new managed memory features just releases with ROCm 4.3, and so far I have learned that xnack+ is required to be enabled on the device for this to work. Based on this:
https://rocmdocs.amd.com/en/latest/ROCm_Compiler_SDK/ROCm-Native-ISA.html#processors
my gfx803 card has xnack support but it's disabled by default. How do I enable it? My kernel has CONFIG_HMM_MIRROR=y, so I think all the other criteria are satisfied.
Thank you!
