Add the drm_gem_huge_mnt_create() and drm_gem_get_huge_mnt() helpers to avoid code duplication in the i915, V3D, Panfrost and Panthor drivers. The former creates and mounts a dedicated huge tmpfs mountpoint, for the lifetime of a DRM device, used at GEM object initialization. The latter retrieves the dedicated huge tmpfs mountpoint used by a DRM device. The next commits will port drivers to these helpers. v3: - store huge tmpfs mountpoint in drm_device v4: - return 0 in builds with CONFIG_TRANSPARENT_HUGEPAGE=n - return 0 when huge_mnt already exists - use new vfs_parse_fs_string() helper v5: - remove warning on !dev->huge_mnt and reset to NULL on free - inline drm_gem_huge_mnt_create() to remove func from text and avoid calls in builds with CONFIG_TRANSPARENT_HUGEPAGE=n - compile out drm_device's huge_mnt field in builds with CONFIG_TRANSPARENT_HUGEPAGE=n - add drm_gem_has_huge_mnt() helper v6: - move huge_mnt doc into ifdef'd section - either inline or export drm_gem_huge_mnt_create() v7: - include <drm/drm_device.h> in drm_gem.h v9: - replace drm_gem_has_huge_mnt() by drm_gem_get_huge_mnt() v11: - doc fixes - add Boris and Maíra R-bs Signed-off-by: Loïc Molinari <loic.molinari@collabora.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Maíra Canal <mcanal@igalia.com> Link: https://patch.msgid.link/20251205182231.194072-5-loic.molinari@collabora.com Signed-off-by: Boris Brezillon <boris.brezillon@collabora.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.
