Hi Joerg and all,
IDXD kernel work queues were disabled due to the flawed use of kernel VA
and SVA API.
Link:

The solution is to enable it under DMA API where IDXD shared workqueue
users can use ENQCMDS to submit work on buffers mapped by DMA API.
This patchset adds support for attaching PASID to the device's default
domain and the ability to allocate global PASIDs from IOMMU APIs. IDXD
driver can then re-enable the kernel work queues and use them under DMA
API.
This depends on the IOASID removal series. (merged)

Thanks,

Changelog:
v9:
- Fix an IDXD driver issue where user interrupt enable bit got
cleared during device enable/disable cycle. Reported and tested by
Tony Zhu<tony.zhu@xxxxxxxxx>
- Rebased to v6.4-rc7
Thanks for fixing this.
It seems that you missed some review comments for v8. I can help to test
and merge when all comments are addressed.
Best regards,
baolu
