Subject: simplify the mdev interface v4
Date: Mon, 4 Jul 2022 14:51:30 +0200 [thread overview]
Message-ID: <20220704125144.157288-1-hch@lst.de> (raw)
Hi all,
this series signigicantly simplies the mdev driver interface by following
the patterns for device model interaction used elsewhere in the kernel.
Changes since v3:
- make the sysfs_name and pretty_name fields pointers instead of arrays
- add an i915 cleanup to prepare for the above
Changes since v2:
- rebased to vfio/next
- fix a pre-existing memory leak in i915 instead of making it worse
- never manipulate if ->available_instances if drv->get_available is
provided
- keep a parent reference for the mdev_type
- keep a few of the sysfs.c helper function around
- improve the documentation for the parent device lifetime
- minor spellig / formatting fixes
Changes since v1:
- embedd the mdev_parent into a different sub-structure in i916
- remove headers now inclued by mdev.h from individual source files
- pass an array of mdev_types to mdev_register_parent
- add additional patches to implement all attributes on the
mdev_type in the core code
