Public bug reported:
ACPI table is updated for PKA (public key accelerator) HW on bluefield
platforms (by Mellanox/Nvidia).
Platform dependant memory addresses are now defined in ACPI table rather than
defining them in the driver code.
This requires an update in the PKA driver to read these platform dependant
memory addresses from ACPI.
Without this update PKA driver won't function as required and kernel
traces will be seen on startup/loading.
SRU Justification:
[Impact]
* ACPI definitions are updated for PKA (public key accelerator) HW on Bluefield
platforms (by Mellnox/Nvidia).
* ACPI update requires PKA driver update, else kernel traces will be seen on
startup.
* PKA driver won't be loaded and PKA HW will be inaccessible.
[Fix]
* "pka: Use memory addresses defined in ACPI table"
[Testcase]
* On bluefield system startup check if PKA driver is loaded without
any errors. Ex:#dmesg | grep -i pka
[Regression Potential]
* For systems where the ACPI update is not applied but PKA driver update is
applied, will see kernel traces as driver will try to read definitions from
ACPI which are not present. This will lead to failure in loading of PKA driver
and PKA HW will be inaccessible. Solution to this is to update ACPI. All new
bluefield images will have updated ACPI definitions.
* Example kernel trace: [ 9.970155] Call trace:
[ 9.972625] pka_drv_probe+0x41c/0x5f0 [mlxbf_pka]
