INTEL_DEBUG is defined (since 4015e1876a) as:
#define INTEL_DEBUG __builtin_expect(intel_debug, 0)
which unfortunately chops off upper 32 bits from intel_debug
on platforms where sizeof(long) != sizeof(uint64_t) because
__builtin_expect is defined only for the long type.
Fix this by changing the definition of INTEL_DEBUG to be function-like
macro with "flags" argument. New definition returns 0 or 1 when
any of the flags match.
Most of the changes in this commit were generated using:
for c in `git grep INTEL_DEBUG | grep "&" | grep -v i915 | awk -F: '{print $1}' | sort | uniq`; do
perl -pi -e "s/INTEL_DEBUG & ([A-Z0-9a-z_]+)/INTEL_DBG(\1)/" $c
perl -pi -e "s/INTEL_DEBUG & (\([A-Z0-9_ |]+\))/INTEL_DBG\1/" $c
done
but it didn't handle all cases and required minor cleanups (like removal
of round brackets which were not needed anymore).

We don't want to export suballocated resources to external consumers,
for a variety of reasons. First of all, it would be exporting random
other pieces of memory which we may not want those external consumers
to have access to. Secondly, external clients wouldn't be aware of
what buffers are packed together and busy-tracking implications there.
Nor should they be. And those are just the obvious reasons.
When we allocate a resource with the PIPE_BIND_SHARED flag, indicating
that it's going to be used externally, we avoid suballocation.
However, there are times when the client may suddenly decide to export
a texture or buffer, without any prior warning. Since we had no idea
this buffer would be exported, we suballocated it. Unfortunately, this
means we need to transition it to a dedicated allocation on the fly, by
allocating a new buffer and copying the contents over.
Making things worse, this often happens in DRI hooks that don't have an
associated context (which we need to say, run BLORP commands). We have
to create an temporary context for this purpose, perform our blit, then
destroy it. The radeonsi driver uses a permanent auxiliary context
stored in the screen for this purpose, but we can't do that because it
causes circular reference counting. radeonsi doesn't do the reference
counting that we do, but also doesn't use u_transfer_helper, so they
get lucky in avoiding stale resource->screen pointers. Other drivers
don't create an auxiliary context, so they avoid this problem for now.
For auxiliary data, rather than copying it over bit-for-bit, we simply
copy over the underlying data using iris_copy_region (GPU memcpy), and
take whatever the resulting aux state is from that operation. Assuming
the copy operation compresses, the result will be compressed.
v2: Stop using a screen->aux_context and just invent one on the fly to
avoid circular reference counting issues.

Reconfiguring the URB partitioning is likely to cause shader stalls,
as the dividing line between each stage's section of memory is moving.
(Technically, 3DSTATE_URB_* are pipelined commands, but that mostly
means that the command streamer doesn't need to stall.) So it should
be beneficial to update the URB configuration less often.
If the previous URB configuration already has enough space for our
current shader's needs, we can just continue using it, assuming we
are able to allocate the maximum number of URB entries per stage.
However, if we ran out of URB space and had to limit the number of
URB entrties for a stage, and the per-entry size is larger than we
need, we should reconfigure it to try and improve concurrency.
So, we begin tracking the last URB configuration in the context,
and compare against that when updating shader variants.
Cuts 36% of the URB reconfigurations (excluding BLORP) from a
Shadow of Mordor trace, and 46% from a GFXBench Manhattan 3.0 trace.
One nice thing is that this removes the need to look at the old
prog_data when updating shaders, which should make it possible to
unbind shader variants without causing spurious URB updates.

We were emitting 3DSTATE_INDEX_BUFFER on every indexed draw, even if
back-to-back draws referred to the same index buffer. This improves
drawoverhead scores in the DrawElements cases by about 10%, by giving
us even more minimal batches.
When we hit a GPU hang, we failed to reset Surface State Base Address
right away, and would keep hanging until we filled up the binder. Then
we'd finally get it right after a lot of repeated stumbles. Update it
right away so we hopefully hang fewer times before succeeding.
Felix noticed a crash when using INTEL_DEBUG=bat decoding. It turned
out that we were sometimes placing variable length data near the end
of a buffer, and with the decoder guessing random lengths rather than
having an actual count, it was walking off the end and crashing. So
this does more than improve the decoder output.
Unfortunately, this is a bit more complicated than i965's handling,
because we don't have a single state buffer. Various places upload
data via u_upload_mgr, and so there isn't a central place to record
the size. We don't need to catch every single place, however, since
it's only important to record variable length packets (like viewports
and binding tables).
State data also lives arbitrarily long, rather than being discarded on
every batch like i965, so we don't know when to clear out old entries
either. (We also don't have a callback when an upload buffer is
released.) So, this tracking may space leak over time. That's probably
okay though, as this is only a debugging feature and it's a slow leak.
We may also get lucky and overwrite existing entries as we reuse BOs,
though I find this unlikely to happen.
The fact that the decoder works in terms of offsets from a state base
address is also not ideal, as dynamic state base address and surface
state base address differ for iris. However, because dynamic state
addresses start from the top of a 4GB region, and binding tables start
from addresses [0, 64K), it's highly unlikely that we'll get overlap.
We can always improve this, but for now it's better than what we had.
This provides a way for the application to query whether any resets have
happened, which lets us expose "robust" contexts. This also enables the
KHR_robust_buffer_access_behavior tests.
This mechanism lets the driver inform the state tracker about GPU
resets, say for destroying a robust API context and reporting a "device
lost" error to the application, making it take action to deal with this.
The iris batch module now tries to detect that the kernel has banned
our GEM context, creates a new non-banned context, and informs the
iris context module that all assumptions about state are now invalid
and it needs to reinitialize the relevant state.
Based on Chris Wilson's work, but significantly rewritten by me.
Just enable it during init_render_context on Gen10+, and move the
Gen9 state tracking into iris_genx_state so it only exists on Gen9.
