Cretaed a Daemon to modprobe vdu drivers after xclbin load.
Problem solved by the commit
in new platform, vdu drivers would be in blacklist at boot time. These modules should be loaded once dynamic region is loaded. As there is no easy way, we have to create a daemon which is going to do this job This is not a clean solution, but there is no other option to support this usecase.
Bug / issue (if any) fixed, which PR introduced the bug, how it was discovered
NA
How problem was solved, alternative solutions (if any) and why they were rejected
Created a daemon which waits for the load_pdi_done sysfs node to modprobe vdu modules. This sysfs node is set to 1 by zocl after succesful xclbin load. (xclbin should contain BITSREAM_PARTIAL_PDI section. This check is required as there can be ps kernel only xclbins).
Risks (if any) associated the changes in the commit
not a scalable solution. Daemon and zocl are running asynchronous.
What has been tested and how, request additional testing if necessary
vdk5000 qdma to verify the flows.
Documentation impact (if any)
