In order to simplify the calling logic of uadk, a new init2 interface
is added to the cipher algorithm class, which includes hardware device
resource initialization and scheduler initialization.
Changes v2 -> v3:
Remove some redundant opcodes.
Changes v1 -> v2:
init2 interface and dynamic loading driver modification for splitting
Longfang Liu (2):
uadk/cipher: add the init2 interface for cipher
uadk/sec: adapt the sec module to the dynamic loading framework

s390 mdev maintainers,
Can I ask your help to test this with the two S390 mdev drivers? Now
that gvt is passing and we've covered alot of the QA ground it is a
good time to run it.
Take the branch from here:
https://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd.git/log/?h=for-…
And build the kernel with
CONFIG_VFIO_CONTAINER=n
CONFIG_IOMMUFD=y
CONFIG_IOMMUFD_VFIO_CONTAINER=y
And your existing stuff should work with iommufd providing the iommu
support to vfio. There will be a dmesg confirming this.
Let me know if there are any problems!
If I recall there was some desire from the S390 platform team to start
building on iommufd to create some vIOMMU acceleration for S390
guests, this is a necessary first step.
Thanks,
Jason
