Changelog
nvidia-graphics-drivers-450 (450.80.02-0ubuntu0.18.04.1) bionic; urgency=medium
* New upstream release (LP: #1897910):
- Improvements:
o Added a new system-level interface using nvidia-capabilities
via /dev for Multi-Instance GPU (MIG) on NVIDIA A100.
For more information on these new device node capabilities,
refer to the MIG user guide.
o Added support for CUDA compatibility for CUDA 11.1, where CUDA
11.1 applications will work on supported GPUs when used with
drivers >= 450.80.00 on Linux. Refer to CUDA Compatibility for
more information.
- Fixed Issues:
o Various security issues were addressed. For additional details
on the med-high severity issues, review the NVIDIA Security
Bulletin 5075.
o Fixed an issue where, when NVLink training encounters a fatal
error, link training is still considered successful resulting
in broken nodes assigned to clients. An escape case in the
NVLink link state reporting caused the driver to report the
links as "Active" and functional even though the link had
received a fatal error. This fatal error does not allow
traffic to be sent over the link, and thus would cause P2P
apps to fail. This is a reporting issue, but not a
functionality issue. The lacking reporting case was
addressed, so the failing link state is properly reported.
o Fixed a software race condition that caused link training
failure (CUDA_ERROR_LAUNCH_FAILED). A race condition within
the driver polling code caused a false failure in some of
the link training steps. This causes the driver to not
continue link training even though training actually was
successful up to that point. The fix corrects these
sequences so that these false failures no longer happen.
* debian/templates/control:
- Provide cuda 11.0-1 and 11.0-1.
