That is: the five least significant bits provide the values of
'bits' and 'offset' which is the case for all hardware currently
supported by NIR and using the bfm/bfe instructions.
This patch also changes the lowering of bitfield_insert/extract

This commit moves the sysvals to a separate, new constant buffer

- Fix disk cache num_cbufs calculation
- Fix passthrough TCS to report num_cbufs = 1 so upload actually occurs
- Change upload_sysvals to assert that num_cbufs > 0 when
num_system_values > 0.

I neglected to mark cbuf0_needs_upload = false after uploading it.
The obvious fix regressed user clip plane tests, because of a second

We want to know if a given slice of a buffer is initialized at a
particular point in the execution of the program. This is accomplished
easily enough -- start out uninitialized and upon an operation writing
to the buffer, mark it initialized.
The motivation is to optimize away expensive operations (like wallpaper
blits) when reading from an uninitialized buffer; since it's
uninitialized, the results of these operations are undefined, and it's
legal to take the fast path ^_^

This is a rather complex change, adding a lot of code but ideally
cleaning up quite a bit as we go.
Within a batch (single frame), there are multiple distinct Mali job
types: SET_VALUE, VERTEX, TILER, FRAGMENT for the few that we emit right
now (eventually more for compute and geometry shaders). Each hardware
job has a mali_job_descriptor_header, which contains three fields of
interest: job index, a dependencies list, and a next job pointer.
The next job pointer in each job is used to form a linked list of
submitted jobs. Easy enough.
The job index and dependencies list, however, are used to form a
dependency graph (a DAG, where each hardware job is a node and each
dependency is a directed edge). Internally, this sets up a scoreboarding
data structure for the hardware to dispatch jobs in parallel, enabling
(for example) vertex shaders from different draws to execute in parallel
while there are strict dependencies between tiling the geometry of a
draw and running that vertex shader.
For a while, we got by with an incredible series of total hacks,
manually coding indices, lists, and dependencies. That worked for a
moment, but combinatorial kaboom kicked in and it became an
unmaintainable mess of spaghetti code.
We can do better. This commit explicitly handles the scoreboarding by
providing high-level manipulation for jobs. Rather than a command like
"set dependency #2 to index 17", we can express quite naturally "add a
dependency from job T on job V". Instead of some open-coded logic to
copy a draw pointer into a delicate context array, we now have an
elegant exposed API to simple "queue a job of type XYZ".
The design is influenced by both our current requirements (standard ES2
draws and u_blitter) as well as the need for more complex scheduling in
the future. For instance, blits can be optimized to use only a tiler
job, without a vertex job first (since the screen-space vertices are
known ahead-of-time) -- causing tiler-only jobs. Likewise, when using
transform feedback with rasterizer discard enabled, vertex jobs are
created (to run vertex shaders) with no corresponding tiler job. Both of
these cases break the original model and could not be expressed with the
open-coded logic. More generally, this will make it easier to add
support for compute shaders, geometry shaders, and fused jobs (an
optimization available on Bifrost).
Incidentally, this moves quite a bit of state from the driver context to
the batch, which helps with Rohan's refactor to eventually permit
pipelining across framebuffers (one important outstanding optimization
for FBO-heavy workloads).
v2: Add comment explaining the meaning of "primary batch" as suggested
by Tomeu (trivial - not reviewed).

Most vertex data lives in user VBOs in IRIS_MEMZONE_OTHER, which
typically have high bits set to 0xffff. The shader draw parameters were
being uploaded in IRIS_MEMZONE_DYNAMIC, which have high bets set to 0x2.
This was causing a lot of ping-ponging of high bits, leading to
unnecessary VF cache flushing.
Cuts 7.2% of the flushes in the Civizilation VI demo on Kabylake GT2.
If there is no buffer, then it doesn't matter. Leave the old stale
high bits in place (for next time) and don't bother invalidating.
Cuts 5.6% of the flushes in the Civilization VI demo on Kabylake GT2.
If a buffer has no usage history, we don't have any read only cache
invalidates to do. If we've written it with the CPU, we don't need
to flush the render cache. The only bit remaining is the CS stall
from iris_flush_bits_for_history. We can just skip the PIPE_CONTROL
in this case.
This is pretty common - an app creates a buffer, fills it with data,
and then binds it for some purpose.
Cuts 36% of the flushes in Manhattan 3.0 on Kabylake GT2.
Instead of using the combined iris_flush_and_dirty_for_history, use
iris_flush_bits_for_history directly - we were already using the split
out iris_dirty_for_history. There's no need to dirty twice, and we can
avoid the looping altogether for non-buffers.
My intention was to have iris_copy_region not do flushing, and leave
that up to the callers. iris_resource_copy_region needs to do this,
but iris_transfer_flush_region was already doing it. The net result
was that we were doing it twice for transfers.
So, move the flushing from iris_copy_region to iris_resource_copy_region
so that it only happens in the callers as I intended.
