We lower NIR's load_constant to load_global_constant, which uses A64
bindless messages. As such, we do the following math to produce the
address for each load:
base_lo@32 <- BRW_SHADER_RELOC_CONST_DATA_ADDR_LOW
base_hi@32 <- BRW_SHADER_RELOC_CONST_DATA_ADDR_HIGH
base@64 <- pack_64_2x32_split(base_lo, base_hi)
addr@64 <- iadd(base@64, u2u64(offset@32))
On platforms that emulate 64-bit math, we have to emit additional code
for the 64-bit iadd to handle the possibility of a carry happening and
affecting the top bits.
However, NIR constant data is always uploaded adjacent to the shader
assembly, in the same buffer. These buffers are required to live in a
4GB region of memory starting at Instruction State Base Address. We
always place the base address at a 4GB address. So the constant data
always lives in a buffer entirely contained within a 4GB region, which
means any offsets from the start of the buffer cannot possibly affect
the high bits.
So instead, we can simply do a 32-bit addition between the low bits of
the base and the offset, then pack that with the unchanged high bits.
On anv, INSTRUCTION_STATE_POOL_MIN_ADDRESS is 8GB, so the high bits are
always 0x2. We don't even need to patch that portion of the address and
can just use an immediate value. We do still need to pack, however.

The anv_execbuf_add_bo() function already sets the offsets for the
exec_objects. Since we're always using softpin and never using
relocations all these objects should have non-changing offsets, all
set during anv_bo creation and never changed. Not only we should not
change these offsets, we definitely don't change them between
anv_execbuf_add_bo() and this loop we're removing.
Previously, we'd have the offset set as -1 for BOs that had never been
submitted when we were not using softpin.
Notice that with games we can have several hundreds of BOs in this
array.

Commit 582bf4d9 turned on write-combining for most (all?) memory
allocations. This caused a fairly large performance drop in some of
our VMware tests (application traces, such as Windows Metro Paint).
This patch adds a third memory type configuration: DEVICE_LOCAL,
HOST_VISIBLE, HOST_COHERENT. This is uncached. Then, in
anv_AllocateMemory() we only use write-combining for this uncached
type. This memory type is found in the Intel Windows Vulkan driver.
And according to
https://asawicki.info/news_1740_vulkan_memory_types_on_pc_and_how_to_use_them
uncached memory correlates to write-combined memory.
This fixes our performance regression (and actually produced the

Three reasons for that:
0. The operation we're doing here is actually a reallocation.
1. The newer code is, IMHO, easier to read.
2. Realloc has this property where sometimes, when possible, it will
expand your array without moving it somewhere else, so it doesn't
need to copy the memory contents, returning the original pointer
back to you. I did some analysis and while that case is not common,
it does happen sometimes in real world applications (I could see it
happening in Shootergame and Aztec Ruins, but not Dota 2), so we're
able to save a few CPU cycles.

This is the only code path where we don't run anv_execbuf_finish() in
case anv_execbuf_add_bo() fails. While there is not a bug in the
current tree, I recently made an (uncommitted) modification that
started leaking memory and made me realize the lack of cleanup here.
If we had anv_execbuf_finish() being called upon error like we're
going to have after this patch my modification wouldn't have caused
the memory leak.
I think it's much safer and future-proof if we're able to operate
under the assumption that whatever is allocated and set to anv_execbuf
will be dealt with upon failure of anything else related to it, so
functions that fail should only be required to free pointers not yet
assigned to anv_execbuf.

path. The one I was specifically using here is:

In anv_execbuf_add_syncobj(), we try to not create or use
exec->syncobj_values if we don't need to. But when we figure we're
going to need it (i.e., when timeline_value is not zero), then we
create exec->syncobj_values with vk_zalloc, which means every previous
value is set to zero, as it should be. This is all correct.
The problem starts when we add a 16th element. In this case we double
exec->syncobj_array_length and realloc the buffer by using vk_alloc
and copying the old array to the new one. After that, we write the
timeline_value to the array only if it's not zero, and that's the
problem: since we just used vkalloc and memcpy, we don't have any
guarantees that the new array will be zero after the 16th element, and
if timeline_value is zero we write nothing to that position.
Once we start using exec->syncobj_values we have to commit to using
it, so the "if (timeline_value)" check near the end of the function
has to be changed to "if (exec->syncobj_values)", so we actually set
elements after the 16th to zero when they need to be zero. Another
approach to fix this would be to memset the new elements once we
double syncobj_array_length.
In practice, I couldn't find any application or deqp test that used
more than 3 elements in exec->syncobj_array_length, and we need more
than 16 elements in order to be able to reproduce the bug, so I'm not
aware of any real-world bug that goes away with this patch. This issue
was found while reading code.
If we craft a little Vulkan program that submits a ton of timeline and
binary semaphores on vkQueueSubmit, then waits for them, we get the
following error without this patch:
MESA: error: ../../src/intel/vulkan/anv_batch_chain.c:1910: execbuf2 failed: Invalid argument (VK_ERROR_DEVICE_LOST)
