'ring' is an old deprecated term for a GPU engine. Chris Wilson wants to use the name for what is currently known as an intel_ringbuffer, but it will be dreadfully confusing if some rings are ringbuffers but other rings are still engines. So this patch changes the names of a bunch of parameters called 'ring' to either 'engine' or 'engine_id' according to what they actually are.

/**
|
|
* DOC: Memory Objects Control State (MOCS)
|
|
*
|
|
* Motivation:
|
|
* In previous Gens the MOCS settings was a value that was set by user land as
|
|
* part of the batch. In Gen9 this has changed to be a single table (per ring)
|
|
* that all batches now reference by index instead of programming the MOCS
|
|
* directly.
|
|
*
|
|
* The one wrinkle in this is that only PART of the MOCS tables are included
|
|
* in context (The GFX_MOCS_0 - GFX_MOCS_64 and the LNCFCMOCS0 - LNCFCMOCS32
|
|
* registers). The rest are not (the settings for the other rings).
|
|
*
|
|
* This table needs to be set at system start-up because the way the table
|
|
* interacts with the contexts and the GmmLib interface.
|
|
*
|
|
*
|
|
* Implementation:
|
|
*
|
|
* The tables (one per supported platform) are defined in intel_mocs.c
|
|
* and are programmed in the first batch after the context is loaded
|
|
* (with the hardware workarounds). This will then let the usual
|
|
* context handling keep the MOCS in step.
