Details

eid_bcm_kthreads.txt is the entity definition file for Broadcom kernel threads.
Unlike other entity files all eids are numerical and define CPU scheduling of each kthread.

It is interpreted by libcms_util.so for the Broadcom system daemon smd.

Each entry is encapsulated in a BEGIN / END clause and my contain:

  • eid - the Entity ID, an enum defined in cms_eid.h
  • name - the name of an executable to launch unless path or altPath are specified
  • runArgs - optional commandline arguments to pass
  • flags - property flags also defined in cms_eid.h

The flags may define an automatical launch of the respective executable:

  • EIF_LAUNCH_IN_STAGE_1 - launch during stage 1 of CMS startup
  • EIF_LAUNCH_ON_BOOT - launch on system boot (during stage 2)

Executables which are EIF_MESSAGING_CAPABLE connect smd through the smd_messaging_server_addr socket.

Full quote 7581 fw 7.17: 

#
# The entities listed in this file are kernel threads.
# Kernel threads should use EID 4000-4999 (see cms_eid.h)
# This range is further subdivided:
# -- Linux kernel threads: 4000-4399
# -- Broadcom kernel threads: 4400-4699
# -- Customer kernel threads: 4700-4999
