Subject: [PATCH 10/11] vfio-pci: introduce vfio_pci_core subsystem driver
Date: Thu, 3 Jun 2021 19:08:08 +0300	[thread overview]
Message-ID: <20210603160809.15845-11-mgurtovoy@nvidia.com> (raw)
In-Reply-To: <20210603160809.15845-1-mgurtovoy@nvidia.com>

Now that vfio_pci has been split into two source modules, one focusing
on the "struct pci_driver" (vfio_pci.c) and a toolbox library of code
(vfio_pci_core.c), complete the split and move them into two different
modules.

As before vfio_pci.ko continues to present the same interface under
sysfs and this change will have no functional impact.

Below is an example for adding new driver that will use vfio pci
subsystem:

	+---------------------------------------------------+
	|                                                   |
	|                     VFIO                          |
	|                                                   |
	+---------------------------------------------------+

	+---------------------------------------------------+
	|                                                   |
	|                  VFIO_PCI_CORE                    |
	|                                                   |
	+---------------------------------------------------+

	+----------+ +---------------+ +--------------------+
	|          | |               | |                    |
	| VFIO_PCI | | MLX5_VFIO_PCI | | HISILICON_VFIO_PCI |
	|          | |               | |                    |
	+----------+ +---------------+ +--------------------+

Splitting into another module and adding exports allows creating new HW
specific vfio_pci drivers that can implement device specific
functionality, such as VFIO migration interfaces or specialized device
requirements.
