I know that, in the grand scheme of things, this isn't significant.
The problem is: now that I know the hole is there, my OCD won't allow
me to sleep until it's fixed.
We went from:
struct vk_object_base {
VK_LOADER_DATA _loader_data; /* 0 8 */
VkObjectType type; /* 8 4 */
/* XXX 4 bytes hole, try to pack */
struct vk_device * device; /* 16 8 */
struct vk_instance * instance; /* 24 8 */
_Bool client_visible; /* 32 1 */
/* XXX 7 bytes hole, try to pack */
struct util_sparse_array private_data; /* 40 24 */
/* --- cacheline 1 boundary (64 bytes) --- */
char * object_name; /* 64 8 */
/* size: 72, cachelines: 2, members: 7 */
/* sum members: 61, holes: 2, sum holes: 11 */
/* last cacheline: 8 bytes */
};
to:
struct vk_object_base {
VK_LOADER_DATA _loader_data; /* 0 8 */
VkObjectType type; /* 8 4 */
_Bool client_visible; /* 12 1 */
/* XXX 3 bytes hole, try to pack */
struct vk_device * device; /* 16 8 */
struct vk_instance * instance; /* 24 8 */
struct util_sparse_array private_data; /* 32 24 */
char * object_name; /* 56 8 */
/* size: 64, cachelines: 1, members: 7 */
/* sum members: 61, holes: 1, sum holes: 3 */
};
which is cool because now the struct nicely fits in a cacheline.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
