[Mesa-dev] [vulkan][intel] SIGBUS, Bus error during command buffer recording

[Vyacheslav Gonakhchyan]

Hi!

When recording command buffer I get error:

Program received signal SIGBUS, Bus error.

anv_state_stream_alloc (stream=stream at entry=0x55559dbf9dd8, size=64,
alignment=alignment at entry=32) at vulkan/anv_allocator.c:913

I enabled validation layers and everything is fine (no output). This
happens for push constants. I use 80 bytes size. I have 128 bytes on my
system. I send the same range for both stages. The function that records
buffer: https://pastebin.com/vN2WjA1W
I use Intel Corporation HD Graphics 630. I increased dedicated memory to
1024MB and nothing changed. I also tried to reduce push constant size to 64
(send only matrix) and it did not help. What could be the reason?

Thanks,
Vyacheslav
