- * There are various types of Mali jobs:
- *
- * - WRITE_VALUE: generic write primitive, used to zero tiler field
- * - VERTEX: runs a vertex shader
- * - TILER: runs tiling and sets up a fragment shader
- * - FRAGMENT: runs fragment shaders and writes out
- * - COMPUTE: runs a compute shader
- * - FUSED: vertex+tiler fused together, implicit intradependency (Bifrost)
- * - GEOMETRY: runs a geometry shader (unimplemented)
- * - CACHE_FLUSH: unseen in the wild, theoretically cache flush
- *
- * In between a full batch and a single Mali job is the "job chain", a series
- * of Mali jobs together forming a linked list. Within the job chain, each Mali
- * job can set (up to) two dependencies on other earlier jobs in the chain.
- * This dependency graph forms a scoreboard. The general idea of a scoreboard
- * applies: when there is a data dependency of job B on job A, job B sets one
- * of its dependency indices to job A, ensuring that job B won't start until
- * job A finishes.
- *
- * More specifically, here are a set of rules:
- *
- * - A write value job must appear if and only if there is at least one tiler
- * job, and tiler jobs must depend on it.
- *
- * - Vertex jobs and tiler jobs are independent.
- *
- * - A tiler job must have a dependency on its data source. If it's getting
- * data from a vertex job, it depends on the vertex job. If it's getting data
- * from software, this is null.
- *
- * - Tiler jobs must depend on the write value job (chained or otherwise).
- *
- * - Tiler jobs must be strictly ordered. So each tiler job must depend on the
- * previous job in the chain.
- *
- * - Jobs linking via next_job has no bearing on order of execution, rather it
- * just establishes the linked list of jobs, EXCEPT:
- *
- * - A job's dependencies must appear earlier in the linked list (job chain).
- *
- * Justification for each rule:
- *
- * - Write value jobs are used to write a zero into a magic tiling field, which
- * enables tiling to work. If tiling occurs, they are needed; if it does not,
- * we cannot emit them since then tiling partially occurs and it's bad.
- *
- * - The hardware has no notion of a "vertex/tiler job" (at least not our
- * hardware -- other revs have fused jobs, but --- crap, this just got even
- * more complicated). They are independent units that take in data, process
- * it, and spit out data.
- *
- * - Any job must depend on its data source, in fact, or risk a
- * read-before-write hazard. Tiler jobs get their data from vertex jobs, ergo
- * tiler jobs depend on the corresponding vertex job (if it's there).
- *
- * - The tiler is not thread-safe; this dependency prevents race conditions
- * between two different jobs trying to write to the tiler outputs at the
- * same time.
- *
- * - Internally, jobs are scoreboarded; the next job fields just form a linked
- * list to allow the jobs to be read in; the execution order is from
- * resolving the dependency fields instead.
- *
- * - The hardware cannot set a dependency on a job it doesn't know about yet,
- * and dependencies are processed in-order of the next job fields.
