@ -16,7 +16,16 @@ Description: Allow the root user to disable/enable in runtime the clock
gating mechanism in Gaudi. Due to how Gaudi is built, the
clock gating needs to be disabled in order to access the
registers of the TPC and MME engines. This is sometimes needed
during debug by the user and hence the user needs this option
during debug by the user and hence the user needs this option.
The user can supply a bitmask value, each bit represents
a different engine to disable/enable its clock gating feature.
The bitmask is composed of 20 bits:
0 - 7 : DMA channels
8 - 11 : MME engines
12 - 19 : TPC engines
The bit's location of a specific engine can be determined
using (1 << GAUDI_ENGINE_ID_*). GAUDI_ENGINE_ID_* values
are defined in uapi habanalabs.h file in enum gaudi_engine_id

2) Device creation with multiple proto mode enabled
2) Device creation with multiproto mode enabled
There are two ways to create a bareudp device for MPLS & IP with multiproto mode
enabled.
The multiproto mode allows bareudp tunnels to handle several protocols of the
same family. It is currently only available for IP and MPLS. This mode has to
be enabled explicitly with the "multiproto" flag.

a) ip link add dev bareudp0 type bareudp dstport 6635 ethertype ipv4 multiproto

For an IPv4 tunnel the multiproto mode allows the tunnel to also handle
IPv6.
b) ip link add dev bareudp0 type bareudp dstport 6635 ethertype mpls_uc multiproto
For MPLS, the multiproto mode allows the tunnel to handle both unicast
