Public bug reported:
SRU Justification:
[Impact]
There is a new feature request to replace the soft reset with a graceful reboot.
We will use acpi events triggered by the irq in the pwr-mlxbf file to trigger
the graceful reboot.
[Fix]
* Change the handling of GPIO7 (BF2) and GPIO6 (BF3). This gpio will trigger a
graceful reboot instead of
a forced reboot (soft reset). This is an acpi event.
[Test Case]
* trigger the gpio toggling from the BMC: ipmitool raw 0x32 0xA1 0x02
This should trigger a graceful reboot of the DPU.
[Regression Potential]
* make sure it works on BF2 and BF3
** Affects: linux-bluefield (Ubuntu)
Importance: Undecided
