Vadym Shovkoplias 55c71217ec driconf: Add a limit_trig_input_range option
With this option enabled range of input values for fsin and fcos is
limited to [-2*pi : 2*pi] by calculating the reminder after 2*pi modulo
division. This helps to improve calculation precision for large input
arguments on Intel.

Kenneth Graunke ab47cad4fb iris: Rename surface_base_address to binder_address in a few places
On Gfx11+, we're going to stop changing Surface State Base Address
and instead start changing the Binding Table Pool address instead.

So, rename a few things to track the last binder address, which is
what we're actually changing, regardless of how we program it.

Nanley Chery 2944f49610 intel: Parse INTEL_NO_HW for devinfo construction
This commit does several things:

* Unify code common to several drivers by evaluating INTEL_NO_HW within
  intel_get_device_info_from_fd (suggested by Jordan).
* For drivers that keep a copy of the intel_device_info struct, a
  separate copy of the no_hw field is now unnecessary. Remove them.
* Minimize kernel queries when INTEL_NO_HW is true. This is done for
  code simplification, but we may find reason to undo this later on.

Ian Romanick 42c34e1ac8 iris: Enable threaded shader compilation
There are a couple minor things that can be improved:

1. Eliminate (or reduce) the dynamic allocation of the
threaded_compile_job.

2. For apps like shader-db, improve the case where nr_threads=0.  Right
now this adds thread switching and mutex overhead.

3. Other performance improvements?  iris_uncompiled_shader::variants has
some special properties that make it ripe for replacement with a
lockless list.  Without gathering some data, it's hard to guess what
impact that could have.

Kenneth Graunke 4256f7ed58 iris: Fill out scratch base address dynamically
Now that shaders are shared between contexts, we can't pre-bake the
shader scratch address into the derived 3DSTATE_XS packets.  Scratch
buffers are and must be per-context, as multiple contexts could be
executing shaders using scratch at the same time.

So instead, we leave that field blank when pre-filling those packets
up-front, and merge in the actual address when emitting them.  It's
a little more overhead, but only in the case where scratch is used.

Marcin Ślusarz 9f19662550 iris: remove iris_monitor_config
perf_cfg is enough - it already contains almost all necessary
information and is constructed in a more optimal way (O(n) vs O(n^2)
- it uses hash table to build the unique counter list).

"Almost all", because it doesn't contain OA raw counters, but
we should have not exposed them anyway. Quoting Mark Janes:
"I see no reason to include the OA raw counters in the list that
are provided to the user. They are unusable.
The MDAPI library can be used to configure raw counters in a way
that provides esoteric metrics, but that library is written against
INTEL_performance_query."

Francisco Jerez eb5d1c2722 iris: Annotate all BO uses with domain and sequence number information.
Probably the most annoying patch to review from the whole series --
Mark every buffer object use as accessed through some caching domain
with the sequence number of the current synchronization section of the
batch.  The additional argument of iris_use_pinned_bo() makes sure I'd
have gotten a compile error if I had missed any buffer added to the
batch validation list.

There are only a few exceptions where a buffer is left untracked while
adding it to the validation list, justified below:

 - Batch buffers: These are strictly read-only for the moment.

 - BLORP buffer objects: Their seqnos are bumped manually at the end
   of iris_blorp_exec() instead, in order to avoid plumbing domain
   information through BLORP address combining.

 - Scratch buffers: The contents of these are strictly thread-local.

 - Shader images and SSBOs: Accesses of these buffers are explicitly
   synchronized at the API level.

v2: Opt out of tracking more aggressively (Ken): In addition to the
    above, surface states, binding tables, instructions and most
    dynamic states are now left untracked, which means a *lot* more BO
    uses marked IRIS_DOMAIN_NONE which need to be reviewed extremely
    carefully, since the cache tracker won't be able to provide any
    coherency guarantees for them.
