[PATCH 0/3] virtio-gpu: Add user pointer and HSAKMT support enhancements

[Honglei Huang <honghuan@amd.com>]

This patch series introduces three key enhancements to virtio-gpu to improve
memory management and GPU virtualization capabilities:

1. VIRTIO_GPU_BLOB_FLAG_USE_USERPTR support: Enables user pointer mapping
   for blob resources, allowing guest applications to use user-allocated 
   memory for GPU resources more efficiently.

2. Configurable HSAKMT capset support: Provides better control over HSAKMT
   functionality with a new device property "hsakmt=on" to avoid exposing
   unsupported capabilities to guests.

3. VIRTIO_GPU_F_RESOURCE_USERPTR feature support: Introduces a new virtio-gpu
   feature flag with configurable "userptr=on" device property to enable
   user pointer resources for enhanced memory management.

These patches work together to provide more flexible and efficient memory
management between guest and host in GPU virtualization scenarios. The
changes are backward compatible and controlled by new device properties.

Usage examples:
  -device virtio-gpu-gl,hsakmt=on,userptr=on

The series has been tested with GPU workloads requiring advanced memory
management capabilities.
