* For each block that can be dynamically allocated, it can be either
- * free, or pending/in-use by a client. The updates happen in three steps:
+ * free:
+ * The block is free.
+ *
+ * pending:
+ * The block is allocated to some client and not free.
+ *
+ * configured:
+ * The block is allocated to some client, and assigned to that
+ * client in MDP5_MDP_SMP_ALLOC registers.
+ *
+ * inuse:
+ * The block is being actively used by a client.
+ *
+ * The updates happen in the following steps:
*
* 1) mdp5_smp_request():
* When plane scanout is setup, calculate required number of
- * blocks needed per client, and request. Blocks not inuse or
- * pending by any other client are added to client's pending
- * set.
+ * blocks needed per client, and request. Blocks neither inuse nor
+ * configured nor pending by any other client are added to client's
+ * pending set.
+ * For shrinking, blocks in pending but not in configured can be freed
+ * directly, but those already in configured will be freed later by
+ * mdp5_smp_commit.
*
* 2) mdp5_smp_configure():
* As hw is programmed, before FLUSH, MDP5_MDP_SMP_ALLOC registers
* are configured for the union(pending, inuse)
+ * Current pending is copied to configured.
+ * It is assumed that mdp5_smp_request and mdp5_smp_configure not run
+ * concurrently for the same pipe.
*
* 3) mdp5_smp_commit():
- * After next vblank, copy pending -> inuse. Optionally update
+ * After next vblank, copy configured -> inuse. Optionally update
* MDP5_SMP_ALLOC registers if there are newly unused blocks
*
+ * 4) mdp5_smp_release():
+ * Must be called after the pipe is disabled and no longer uses any SMB
+ *
* On the next vblank after changes have been committed to hw, the
* client's pending blocks become it's in-use blocks (and no-longer
* in-use blocks become available to other clients).
