    5 The [source:soft/giet_vm/giet_common/locks.c locks.c] and [source:soft/giet_vm/giet_common/locks.h locks.h] files define the functions used to take & release the kernel locks. These locks are implemented as spin-locks with a waiting queue (based on a ticket allocator scheme) to enforce fairness and avoid live-lock situations. The GIET_LOCK_MAX_TICKET define the wrapping value for the ticket allocator.
     5The [source:soft/giet_vm/giet_common/locks.c locks.c] and [source:soft/giet_vm/giet_common/locks.h locks.h] files define the functions used by the kernel to take & release  locks protecting exclusive access to a shared resource. These locks are implemented as spin-locks, with a waiting queue (based on a ticket allocator scheme) to enforce fairness and avoid live-lock situations. The GIET_LOCK_MAX_TICKET define the wrapping value for the ticket allocator.

    77The lock access functions are prefixed by "_" to remind that they can only be executed by a processor in kernel mode.
