Subject: [PATCH v2 11/13] vfio/mdev: Remove mdev_parent_ops
Date: Mon, 26 Apr 2021 17:00:13 -0300	[thread overview]
Message-ID: <11-v2-7667f42c9bad+935-vfio3_jgg@nvidia.com> (raw)
In-Reply-To: <0-v2-7667f42c9bad+935-vfio3_jgg@nvidia.com>

The last useful member in this struct is the supported_type_groups, move
it to the mdev_driver and delete mdev_parent_ops.

Replace it with mdev_driver as an argument to mdev_register_device()

-Physical Device Driver Interface
---------------------------------
-
-The physical device driver interface provides the mdev_parent_ops[3] structure
-to define the APIs to manage work in the mediated core driver that is related
-to the physical device.
-
-The structures in the mdev_parent_ops structure are as follows:
-
-* dev_attr_groups: attributes of the parent device
-* mdev_attr_groups: attributes of the mediated device
-* supported_config: attributes to define supported configurations
-
-A driver should use the mdev_parent_ops structure in the function call to
-register itself with the mdev core driver::
+When a driver wants to add the GUID creation sysfs to an existing device it has
+probe'd to then it should call:
 
 	extern int  mdev_register_device(struct device *dev,
-	                                 const struct mdev_parent_ops *ops);
+	                                 struct mdev_driver *mdev_driver);
+
+This will provide the 'mdev_supported_types/XX/create' files which can then be
+used to trigger the creation of a mdev_device. The created mdev_device will be
+attached to the specified driver.
 
-However, the mdev_parent_ops structure is not required in the function call
-that a driver should use to unregister itself with the mdev core driver::
+When the driver needs to remove itself it calls:
 
 	extern void mdev_unregister_device(struct device *dev);
 
+Which will unbind and destroy all the created mdevs and remove the sysfs files.
