I'm working on LS1043 which have four cores, and boot the system with the argument "bportals=s0-2 qportals=s0-2", which meant we have three QMan portals
root@ls1043ardb:~# cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3
43: 0 0 54 0 GIC 216 Level QMan portal 2
44: 0 52 0 0 GIC 218 Level QMan portal 1
45: 51 0 0 0 GIC 220 Level QMan portal 0
In the DTS file, I configure fm1-mac5 and fm1-mac6 works on Linux, and leave the rest for USDPAA.
After that, connect my laptop to fm1-mac5, set the IP address, and ping my laptop from LS1043.
Through command "cat /proc/interrupts", I saw that all the interrupts counters of three QMan portals increased simultaneously.
I have a few questions here,
