nir/xfb: don't assert when xfb_buffer/stride is present but not xfb_offset

In order to allow nir_gather_xfb_info to be used on OpenGL,
specifically ARB_gl_spirv.

So, from OpenGL 4.6 spec, section 11.1.2.1, "Output Variables":

    "outputs specifying both an *XfbBuffer* and an *Offset* are
     captured, while outputs not specifying both of these are not
     captured. Values are captured each time the shader writes to such
     a decorated object."

This implies that are captured if both are present, and not if one of
those are lacking. Technically, it doesn't explicitly point that
having just one or the other is a mistake. In some cases, glslang is
adding some extra XfbBuffer without XfbOffset around, and mentioning
that technically that is not a bug (see issue#1526)

And for the case of Vulkan, as the same glslang issue mentions, it is
not clear if that should be a mistake or not. But even if it is a
mistake, it is not really needed to be checked on the driver, and we
can let the validation layers to check that.

Jason Ekstrand [Wed, 16 Jan 2019 23:40:13 +0000 (17:40 -0600)]
intel/fs: Don't touch accumulator destination while applying regioning alignment rule

In some shaders, you can end up with a stride in the source of a
SHADER_OPCODE_MULH.  One way this can happen is if the MULH is acting on
the top bits of a 64-bit value due to 64-bit integer lowering.  In this
case, the compiler will produce something like this:

mul(8)    acc0<1>UD   g5<8,4,2>UD   0x0004UW      { align1 1Q };
mach(8)   g6<1>UD     g5<8,4,2>UD   0x00000004UD  { align1 1Q AccWrEnable };

The new region fixup pass looks at the MUL and sees a strided source and
unstrided destination and determines that the sequence is illegal.  It
then attempts to fix the illegal stride by replacing the destination of
the MUL with a temporary and emitting a MOV into the accumulator:

mul(8)    g9<2>UD     g5<8,4,2>UD   0x0004UW      { align1 1Q };
mov(8)    acc0<1>UD   g9<8,4,2>UD                 { align1 1Q };
mach(8)   g6<1>UD     g5<8,4,2>UD   0x00000004UD  { align1 1Q AccWrEnable };

Unfortunately, this new sequence isn't correct because MOV accesses the
accumulator with a different precision to MUL and, instead of filling
the bottom 32 bits with the source and zeroing the top 32 bits, it
leaves the top 32 (or maybe 31) bits alone and full of garbage.  When
the MACH comes along and tries to complete the multiplication, the
result is correct in the bottom 32 bits (which we throw away) and
garbage in the top 32 bits which are actually returned by MACH.

This commit does two things:  First, it adds an assert to ensure that we
don't try to rewrite accumulator destinations of MUL instructions so we
can avoid this precision issue.  Second, it modifies
required_dst_byte_stride to require a tightly packed stride so that we
fix up the sources instead and the actual code which gets emitted is
this:

mov(8)    g9<1>UD     g5<8,4,2>UD                 { align1 1Q };
mul(8)    acc0<1>UD   g9<8,8,1>UD   0x0004UW      { align1 1Q };
mach(8)   g6<1>UD     g5<8,4,2>UD   0x00000004UD  { align1 1Q AccWrEnable };

anv/allocator: Add padding information.

It's possible that we still have some space left in the block pool, but
we try to allocate a state larger than that state. This means such state
would start somewhere within the range of the old block_pool, and end
after that range, within the range of the new size.

That's fine when we use userptr, since the memory in the block pool is
CPU mapped continuously. However, by the end of this series, we will
have the block_pool split into different BOs, with different CPU
mapping ranges that are not necessarily continuous. So we must avoid
such case of a given state being part of two different BOs in the block
pool.

This commit solves the issue by detecting that we are growing the
block_pool even though we are not at the end of the range. If that
happens, we don't use the space left at the end of the old size, and
consider it as "padding" that can't be used in the allocation. We update
the size requested from the block pool to take the padding into account,
and return the offset after the padding, which happens to be at the
start of the new address range.

Additionally, we return the amount of padding we used, so the caller
knows that this happens and can return that padding back into a list of
free states, that can be reused later. This way we hopefully don't waste
any space, but also avoid having a state split between two different

anv/allocator: Rework chunk return to the state pool.

This commit tries to rework the code that split and returns chunks back
to the state pool, while still keeping the same logic.

The original code would get a chunk larger than we need and split it
into pool->block_size. Then it would return all but the first one, and
would split that first one into alloc_size chunks. Then it would keep
the first one (for the allocation), and return the others back to the
pool.

The new anv_state_pool_return_chunk() function will take a chunk (with
the alloc_size part removed), and a small_size hint. It then splits that
chunk into pool->block_size'd chunks, and if there's some space still
left, split that into small_size chunks. small_size in this case is the
same size as alloc_size.

The idea is to keep the same logic, but make it in a way we can reuse it
to return other chunks to the pool when we are growing the buffer.

anv/tests: Fix block_pool_no_free test.

There were 2 problems with this test.

First it was comparing highest, which was -1, with an uint32_t. So the
current value would never be higher than that, and the assert would
always be false. It just never reached this point because of the next
problem.

It was always looking for the highest value of each thread and storing
it in thread_max. So a test case like this wouldn't work:

[Thread]: [Blocks]
   [0]: [0, 32, 64, 96]
   [1]: [128, 160, 192, 224]
   [2]: [256, 288, 320, 352]

Not only that would skip values and iterate only over thread number 2,
instead of walking through all of them, but thread_max was also
initialized to -1. And then compared to unsigned blocks[i][next[i].

We fix that by getting the smallest value of each thread, and checking
if it is lower than thread_min, which is initialized to INT32_MAX. And
then we end up walking through all the blocks of all threads. We also
change "blocks" to be int32_t instead of uint32_t, since in some places
(alloc_blocks) it was already referenced as int32_t, and that fixes the
comparison to -1.
