There are some cases where the VS is the only stage enabled, it uses the
entire URB, and the URB is large enough that placing later stages after
the VS exceeds the number of bits for "URB Starting Address".
For example, on Icelake GT2, "varying-packing-simple mat2x4 array" from
Piglit is getting a starting offset of 128 for the GS/HS/DS. But the
field is only large enough to hold an offset of 127.
i965 doesn't hit any genxml assertions because it's still using the old
OUT_BATCH mechanism. 128 << GEN7_URB_STARTING_ADDRESS_SHIFT (57) == 0,
with the extra bit falling off the end. So we place the disabled stage
at the beginning of the URB (overlapping with push constants). This is
likely okay since it's a zero size region (0 entries).
It seems like the Vulkan driver might hit this assertion, however, and
the situation seems harmless. To work around this, always place
disabled stages at the start of the URB, so the last enabled stage can
fill the remaining space without overflowing the field.

First of all, setting iter->name in advance_field is unnecessary because
it gets set by gen_decode_field which gets called immediately after
gen_decode_field in the one call-site. Second, we weren't properly
initializing start_bit and end_bit in the initial condition of
gen_field_iterator_next so the first field of a struct would get printed
wrong if it doesn't start on the first bit. This is fixed by adding a
iter_start_field helper which sets the field and also sets up the other
bits we need. This fixes decoding of 3DSTATE_SBE_SWIZ.

Shader time hard codes an index of the shader time buffer within the

In order to support shader time in the disk shader cache, we'd need to
add the shader time index into the program key. This should work, but
probably is not worth it for this particular debug feature.
Therefore, let's just disable the disk shader cache if the shader time

The various base addresses are simply addresses. There may or may not

Normally, i965 programs STATE_BASE_ADDRESS every batch, and puts all
state for a given base in a single buffer.
I'm working on a prototype which emits STATE_BASE_ADDRESS only once at
startup, where each base address is a fixed 4GB region of the PPGTT.
State may live in many buffers in that 4GB region, even if there isn't
a buffer located at the actual base address itself.
To handle this, we need to save the STATE_BASE_ADDRESS values across
multiple batches, rather than assuming we'll see the command each time.
Then, each time we see a pointer, we need to ask the driver for the BO
map for that data. (We can't just use the map for the base address, as
state may be in multiple buffers, and there may not even be a buffer
at the base address to map.)
v2: Fix things caught in review by Lionel:
- Drop bogus bind_bo.size check.
- Drop "get the BOs again" code - we just get the BOs as needed
