[libvirt] [PATCH v5 0/2] PPC64 support for NVIDIA V100 GPU with NVLink2 passthrough

Posted by Daniel Henrique Barboza 5 years ago

This series adds support for a new QEMU feature for the spapr
(PPC64) machine, NVIDIA V100 + P9 passthrough. Refer to [1]
for the version 7 of this feature (version accepted upstream).


changes in v5:
- patch1:
  * use ARRAY_CARDINALITY instead of hard coding the array size
  * fixed leak of 'file' string inside loop
  * added ATTRIBUTE_UNUSED in the static function to allow build
to succeed without applying the second patch

- patch 2:
  * added QEMU reference of the memory layout of NVLink2 support
  * fixed leak of 'pciAddrStr' string inside loop
  * added curly braces in multi-line statements

Previous version can be found at [2].
