Title:
crypto / qat: unable to init GEN4 device
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Target]
Jammy kernel.
[Impact]
The PCI device cannot be initialized.
This has been fixed in linux v5.18 with the below commits:
- a9dc0d966605 ("crypto: qat - add PFVF support to the GEN4 host driver")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a9dc0d966605
- 642a7d49c249 ("crypto: qat - fix access to PFVF interrupt registers for
GEN4")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=642a7d49c249
[Test Case]
Boot a machine with this device.
Before the patches, the following errors are logged:
> EAL: Probe PCI driver: qat (8086:4941) device: 0000:00:08.0 (socket -1)
> qat_pf2vf_exch_msg(): ACK not received from remote
[Regression Potential]
The patches enable new code for this kind of device only.
It is living in linux for more than 1 years.
The potential regressions are low.
