drm: include drm_print.h where needed

2025-10-31T08:34:52+00:00

There are a gazillion files that depend on drm_print.h being indirectly included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In preparation for removing those includes, explicitly include drm_print.h where needed.

drm: Convert open-coded yes/no strings to yesno()

2022-02-07T21:04:25+00:00

linux/string_helpers.h provides a helper to return "yes"/"no" strings. Replace the open coded versions with str_yes_no(). The places were identified with the following semantic patch: @@ expression b; @@ - b ? "yes" : "no" + str_yes_no(b) Then the includes were added, so we include-what-we-use, and parenthesis adjusted in drivers/gpu/drm/v3d/v3d_debugfs.c. After the conversion we still see the same binary sizes: text data bss dec hex filename 51149 3295 212 54656 d580 virtio/virtio-gpu.ko.old 51149 3295 212 54656 d580 virtio/virtio-gpu.ko 1441491 60340 800 1502631 16eda7 radeon/radeon.ko.old 1441491 60340 800 1502631 16eda7 radeon/radeon.ko 6125369 328538 34000 6487907 62ff63 amd/amdgpu/amdgpu.ko.old 6125369 328538 34000 6487907 62ff63 amd/amdgpu/amdgpu.ko 411986 10490 6176 428652 68a6c drm.ko.old 411986 10490 6176 428652 68a6c drm.ko 98129 1636 264 100029 186bd dp/drm_dp_helper.ko.old 98129 1636 264 100029 186bd dp/drm_dp_helper.ko 1973432 109640 2352 2085424 1fd230 nouveau/nouveau.ko.old 1973432 109640 2352 2085424 1fd230 nouveau/nouveau.ko Signed-off-by: Lucas De Marchi Reviewed-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20220126093951.1470898-10-lucas.demarchi@intel.com

A virtio-gpu vram object is based on range-based allocation. No guest shmemfs backing, so we call drm_gem_private_object_init. This is for host memory without any guest backing (atleast initially).

drm: convert .debugfs_init() hook to return void.

2020-03-18T16:53:28+00:00

As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.
