AM6421: Firewall_Attrs initRegions vs totalRegions

Marko Vejnovic

Part Number: AM6421
Other Parts Discussed in Thread: SYSCONFIG

What is the difference between Firewall_Attrs.initRegions and Firewall_Attrs.totalRegions defined in firewall/v0/firewall.h? It appears that initRegions is used as the count of defined firewall regions. However, I couldn't find what the purpose of Firewall_Attrs.totalRegions is. Doesn't seem like it's used anywhere. Appreciate the help.

Hi Marko,

The Firewall_Attrs.initRegions defines the number of regions to be initialized while Firewall_Attrs.totalRegions defines the total number of regions a particular firewall id can support. The value of Firewall_Attrs.initRegions is determined from the number of regions configured in the Sysconfig for a certain firewall id while the value of Firewall_Attrs.totalRegions is constant and taken from the ${SDK_PATH}/source/drivers/.meta/firewall/soc/firewall_am64x_am243x.json.

Regards,

Prashant
