``cuda-bindings`` 12.9.6 Release notes
7+
======================================
8+
9+
Highlights
10+
----------
11+
12+
* ``cuda.bindings.nvml`` has graduated from experimental (``cuda.bindings._nvml``)
13+
to a fully supported public module with extensive handwritten Pythonic API
14+
coverage spanning ~170 functions across system queries, device discovery,
15+
memory, power, clocks, utilization, thermals, NVLink, and device configuration.
16+
(`PR #1524 <https://github.com/NVIDIA/cuda-python/pull/1524>`_,
17+
`PR #1548 <https://github.com/NVIDIA/cuda-python/pull/1548>`_)
18+
* Add ``nvFatbin`` bindings.
19+
(`PR #1467 <https://github.com/NVIDIA/cuda-python/pull/1467>`_)
20+
* Performance improvement: ``cuda.bindings`` now uses a faster ``enum``
21+
implementation, rather than the standard library's ``enum.IntEnum``.
22+
This leads to much faster import times, and slightly faster attribute access
23+
times.
24+
(`PR #1581 <https://github.com/NVIDIA/cuda-python/pull/1581>`_)
25+
* Multiple performance improvements cumulatively reducing Python-to-C call
26+
overhead through faster ``void *`` conversion, faster result returning,
27+
optimized enum-to-vector conversion, and stack-allocated small arrays.
28+
29+
Bugfixes
30+
--------
31+
32+
* Fixed an issue where the ``CU_POINTER_ATTRIBUTE_DEVICE_ORDINAL`` attribute was
33+
retrieved as an unsigned int, rather than a signed int.
34+
(`PR #1336 <https://github.com/NVIDIA/cuda-python/pull/1336>`_)
35+
* Fixed a use-after-free in ``_HelperInputVoidPtr`` properties when backed by
36+
Python buffer objects.
37+
(`PR #1629 <https://github.com/NVIDIA/cuda-python/pull/1629>`_)
38+
39+
Miscellaneous
40+
-------------
41+
42+
* Faster ``void *`` conversion using stack-allocated buffers instead of heap
43+
allocation.
44+
(`PR #1616 <https://github.com/NVIDIA/cuda-python/pull/1616>`_)
45+
* Faster returning of results from driver, runtime, and NVRTC bindings.
46+
(`PR #1647 <https://github.com/NVIDIA/cuda-python/pull/1647>`_,
47+
`PR #1656 <https://github.com/NVIDIA/cuda-python/pull/1656>`_)
48+
* Faster conversion of enum sequences to vectors by eliminating temporary
49+
Python objects.
50+
(`PR #1667 <https://github.com/NVIDIA/cuda-python/pull/1667>`_)
51+
* Stack-allocated small numeric arrays in driver bindings, reducing heap
52+
allocation overhead.
53+
(`PR #1545 <https://github.com/NVIDIA/cuda-python/pull/1545>`_)
54+
* NVML bindings now use ``cuda_pathfinder`` for library discovery, consistent
55+
with other CUDA libraries.
56+
(`PR #1661 <https://github.com/NVIDIA/cuda-python/pull/1661>`_)
57+
* ``CUDA_HOME`` is no longer required at metadata resolution time (e.g.
58+
``pip install --dry-run``, ``uv lock``); it is only needed at actual build time.
59+
(`PR #1652 <https://github.com/NVIDIA/cuda-python/pull/1652>`_)
60+
61+
Known issues
62+
------------
63+
64+
* Updating from older versions (v12.6.2.post1 and below) via ``pip install -U cuda-python`` might not work. Please do a clean re-installation by uninstalling ``pip uninstall -y cuda-python`` followed by installing ``pip install cuda-python``.
