| pw_sync_baremetal |
| ================= |
| This is a set of backends for pw_sync that works on baremetal targets. It is not |
| ready for use, and is under construction. |
| |
| .. note:: |
| All constructs in this baremetal backend do not support hardware multi-threading |
| (SMP, SMT, etc). |
| |
| .. warning:: |
| It does not perform interrupt masking or disable global interrupts. This is not |
| safe to use yet! |
| |
| ------------------------------------- |
| pw_sync_baremetal's InterruptSpinLock |
| ------------------------------------- |
| The interrupt spin-lock implementation makes a single attempt to acquire the lock |
| and asserts if it is unavailable. It does not perform interrupt masking or disable global |
| interrupts. |
| |
| ------------------------- |
| pw_sync_baremetal's Mutex |
| ------------------------- |
| The mutex implementation makes a single attempt to acquire the lock and asserts if |
| it is unavailable. |
