[Mesa-dev] [PATCH 4/4] i965: Introduce a context-local batch manager

When submitting commands to the GPU every cycle of latency counts;
mutexes, spinlocks, even atomics quickly add to substantial overhead.
This "batch manager" acts as thread-local shim over the buffer manager
(drm_intel_bufmgr_gem). As we are only ever used from within a single
context, we can rely on the upper layers providing thread safety.
This allows us to import buffers from the shared screen (sharing buffers
between multiple contexts, threads and users) and wrap that handle in
our own. Similarly, we will to share the buffer cache between all
users on the file and so allocate from the global threadsafe buffer
manager, will a very small and transient local cache of active buffers.
The batch manager provides a cheap way of busyness tracking and very
efficient batch construction and kernel submission.
The restrictions over and above the generic submission engine in
intel_bufmgr_gem are:
- not thread-safe
- flat relocations, only the batch buffer itself carries
relocations. Relocations relative to auxiliary buffers
must be performed via STATE_BASE
- direct mapping of the batch for writes, expect reads
from the batch to be slow
- the batch is a fixed 64k in size
- access to the batch must be wrapped by brw_batch_begin/_end
- all relocations must be immediately written into the batch
The importance of the flat relocation tree with local offset handling is
that it allows us to use the "relocation-less" execbuffer interfaces,
dramatically reducing the overhead of batch submission.
ivb/bdw OglBatch7 improves by ~20% above and beyond the relocation
speedups in http://cgit.freedesktop.org/~ickle/linux-2.6/commit/?h=nightly&id=d664f006b340ad9b2b68c8b661aa396c0a72d0fb
ISSUES:
* add real kernel feature detection
* aub-annotation support (needs to expose the libdrm_intel aub writers)
* where is the doubly-linked circular list?
* shared mipmap trees between contexts - are they even legal?
* OglMultithread is nevertheless unhappy

which implies that treating the entire context as atomic is an incorrect
assumption
* Add full-ppgtt softpinning support (no more relocations, at least for
the first 4G)
* polish and move to libdrm; though at the cost of sealing the structs?

+ *
+ * Example:
+ * We need to keep a list of struct foo in the parent struct bar, i.e. what
+ * we want is something like this.
+ *
+ * struct bar {
+ * ...
+ * struct foo *list_of_foos; -----> struct foo {}, struct foo {}, struct foo{}
+ * ...
+ * }
+ *
+ * We need one list head in bar and a list element in all list_of_foos (both are of
+ * data type 'struct list').
+ *
+ * struct bar {
+ * ...
+ * struct list list_of_foos;
+ * ...
+ * }
+ *
+ * struct foo {
+ * ...
+ * struct list entry;
+ * ...
+ * }
+ *
+ * Now we initialize the list head:
+ *
+ * struct bar bar;
+ * ...
+ * list_init(&bar.list_of_foos);
+ *
+ * Then we create the first element and add it to this list:
+ *
+ * struct foo *foo = malloc(...);
+ * ....
+ * list_add(&foo->entry, &bar.list_of_foos);
+ *
+ * Repeat the above for each element you want to add to the list. Deleting
+ * works with the element itself.
+ * list_del(&foo->entry);
+ * free(foo);
+ *
+ * Note: calling list_del(&bar.list_of_foos) will set bar.list_of_foos to an empty
+ * list again.
+ *
+ * Looping through the list requires a 'struct foo' as iterator and the
+ * name of the field the subnodes use.
+ *
+ * struct foo *iterator;
+ * list_for_each_entry(iterator, &bar.list_of_foos, entry) {
+ * if (iterator->something == ...)
+ * ...
+ * }
+ *
+ * Note: You must not call list_del() on the iterator if you continue the
+ * loop. You need to run the safe for-each loop instead:
+ *
+ * struct foo *iterator, *next;
+ * list_for_each_entry_safe(iterator, next, &bar.list_of_foos, entry) {
