Title:
Add support for QAT Gen5 device with the 420xx (CPM2.2) firmware
Status in linux-firmware package in Ubuntu:
Fix Released
Status in linux-firmware source package in Noble:
Fix Committed
Status in linux-firmware source package in Oracular:
Fix Released
Bug description:
[ Impact ]
* For QAT Gen5 (available on Intel GraniteRapids-D Kaseyville platform), the
driver qat_420xx
fails to load the firmware and this causes QAT device to not work properly
This is applicable for these kernels:
- Noble generic kernel (6.8) and HWE (6.11)
- Oracular generic kernel (6.11)
[ Test Plan ]
* On boot, this kernel message can be found:
Apr 07 22:05:36 ubuntu kernel: 420xx 0000:01:00.0: Direct firmware load for
qat_420xx_mmp.bin failed with error -2
Apr 07 22:05:36 ubuntu kernel: 420xx 0000:01:00.0: Failed to load MMP
firmware qat_420xx_mmp.bin
Apr 07 22:05:36 ubuntu kernel: 420xx 0000:01:00.0: Failed to load
acceleration FW
* We can also run cpa_sample_code application to validate the QAT
functionality
$ sudo apt install -y qatlib-service qatlib-examples
$ sudo cpa_sample_code
The cpa_sample_code should detect QAT devices and run successfully
[ Where problems could occur ]
* The firmware are standalone binaries and only loaded by the QAT qat_420xx
kernel module
No regression should be expected.
[ Other Info ]
* The firmware files to backport are :
qat_420xx.bin
qat_420xx_mmp.bin
They are both part of the linux-firmware package in Plucky.
