# Helper to generate CIDs for virtio-vsock based communication with processes

# A CID is a 32-bit Context Identifier to be assigned to a crosvm instance
|
|
# and must be unique across the host system. For this purpose, let's take
|
|
# the least significant 25 bits from CI_JOB_ID as a base and generate a 7-bit
|
|
# prefix number to handle up to 128 concurrent crosvm instances per job runner.
|
|
#
|
|
# As a result, the following variables are set:
|
|
# - VSOCK_CID: the crosvm unique CID to be passed as a run argument
|
|
#
|
|
# - VSOCK_STDOUT, VSOCK_STDERR: the port numbers the guest should accept
|
|
# vsock connections on in order to transfer output messages
|
|
#
|
|
# - VM_TEMP_DIR: the temporary directory path used to pass additional
|
|
# context data towards the guest
|
