      Add SVM docu and examples · 164bdf4d
      Torben authored
      Add an extra documentation article for the SVM feature in the documentation folder.
      
      Add new example software for the SVM feature for Rust and C++. Both programs contain four different tests using the arraysum, arrayinit and/or arrayupdate HLS example kernels. They demonstrate how to use the different page migration types provided with this feature.

      Return all buffer after PE release · 1ec629c4
      Torben authored
      If SVM is enabled 'pe.release()' returns all buffers which has been passed to 'pe.start()' as DataTransferAlloc parameter, no matter whether from_device has been set to 'true' or not. This way the user program can regain ownership of all buffers.
      See the SVM pipeline example for a use case.

      Add VirtualAddress param · 3b68f500
      Torben authored
      Add VirtualAddress as additional PEParameter. It is used to pass a virtual pointer to the PE without initiating a migration when using the SVM feature.
      Before the argument is passed to the PE, the runtime checks whether the loaded bitstream supports SVM.

      Switch to write lock and add second try · bdd749c1
      Torben authored
      Hold the mmap_write_lock() instead of mmap_read_lock() for host-to-device migrations to prevent that the CPU and device page fault handler run at the same time. During concurrent page accesses causing a Ping-Pong effect migrations to device failed and most accelerators do not handle the return SLVERRs correctly.
      
      If the migration of pages fail for ODPMs in host-to-device direction, try it a second time (this may happen if a race for a zero-page between device and host occurs).
