Currently, even though V3D 7.1 has 93 performance counters, it is not possible to create counters bigger than 87, as `v3d_perfmon_create_ioctl()` understands that counters bigger than 87 are invalid. Therefore, create a device variable to expose the maximum number of counters for a given V3D version and make `v3d_perfmon_create_ioctl()` check this variable. This commit fixes CTS failures in the performance queries tests `dEQP-VK.query_pool.performance_query.*` [1] Link:ea1f09a5f2[1] Fixes:6fd9487147("drm/v3d: add brcm,2712-v3d as a compatible V3D device") Signed-off-by: Maíra Canal <mcanal@igalia.com> Reviewed-by: Iago Toral Quiroga <itoral@igalia.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240512222655.2792754-3-mcanal@igalia.com
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
