Bug ID: 97961
Summary: radeon: Failed to allocate virtual address for buffer
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: vedran@miletic.net
QA Contact: dri-devel@lists.freedesktop.org
On a Kabini system using kernel 4.8-rc8, Mesa and LLVM git, running GROMACS
OpenCL example 1536 from [1] results in
radeon: Failed to allocate virtual address for buffer:
radeon: size : 4096 bytes
radeon: alignment : 4096 bytes
radeon: domains : 2
radeon: va : 0x000000000948b000
radeon: Failed to deallocate virtual address for buffer:
radeon: size : 4096 bytes
radeon: va : 0x948b000
radeon: Failed to allocate virtual address for buffer:
radeon: size : 4096 bytes
radeon: alignment : 4096 bytes
radeon: domains : 2
radeon: va : 0x000000000948b000
radeon: Failed to deallocate virtual address for buffer:
radeon: size : 4096 bytes
radeon: va : 0x948b000
This is one of the larger examples, so it requires more memory than the
previous ones. I will test the largest example (3072) soon, and I expect it to
crash the same way.
This is a regression. It will be very hard to bisect LLVM and kernel on this
machine as it is really slow, but Mesa is likely bisectable. Let me know if it
is worth it.

GROMACS 2016 runs vanilla on Mesa, but it requires LLVM 4.0, matching libclc,
and the following patch for Mesa:

I believe this was fixed somewhere along the way, I don't get the error
anymore.
