drm/omapdrm: Remove fbdev from struct omap_drm_private

2023-04-06T12:50:05+00:00

The DRM device stores a pointer to the fbdev helper. Remove struct omap_drm_private.fbdev, which contains the same value. No functional changes. v2: * don't clear dev->fb_helper unnecessarily (Tomi) * include omap_fbdev.h in omap_fbdev.c (kernel test robot) Signed-off-by: Thomas Zimmermann Reviewed-by: Tomi Valkeinen Reviewed-by: Emil Velikov Signed-off-by: Tomi Valkeinen Link: https://patchwork.freedesktop.org/patch/msgid/20230403104035.15288-5-tzimmermann@suse.de

drm: Drop drm_framebuffer.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_frambuffer.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_framebuffer.h. Quite a few placs do currently depend on drm_framebuffer.h without actually including it directly. All of those need to be fixed up. v2: Fix up msm some more v2: Deal with ingenic and shmobile as well Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20220614095449.29311-1-ville.syrjala@linux.intel.com Acked-by: Sam Ravnborg Acked-by: Jani Nikula

drm: omapdrm: Replace HTTP links with HTTPS ones

2020-11-10T12:41:22+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

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.

drm/omap: remove checks for return value of drm_debugfs functions

2020-03-18T15:27:14+00:00

Since 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), there is no need to ever check the return value for drm_debugfs_create_files(). Therefore remove the checks for the return value and subsequent error handling in omap_debugfs_init(). These changes also enables the changing of omap_debugfs_init() to return 0 directly. v2: convert omap_debugfs_init() to return 0 instead of void to avoid introduction of build issues and enable individual driver compilation.

drm/omapdrm: drop use of drmP.h

2019-07-17T10:52:55+00:00

Drop use of the deprecated header drmP.h. Rearranged list of include files to match rest of DRM too. The drmP.h file was deleted from the header file, and the necessary includes was added to the .c files to fix build.

drm/omap: gem: Fix mm_list locking

2018-06-28T10:41:05+00:00

- None of the list walkings where protected. - Switch to a mutex since the list walking at device resume time can sleep when pinning buffers through the tiler. Only thing we need to be careful with here is that while we walk the list we can't unreference any gem objects, since the final unref would result in a recursive deadlock. But the only functions that walk the list is the device resume and debugfs dumping, so all safe.

drm/omap: gem: Replace struct_mutex usage with omap_obj private lock

2018-06-28T10:41:05+00:00

The DRM device struct_mutex is used to protect against concurrent GEM object operations that deal with memory allocation and pinning. All those operations are local to a GEM object and don't need to be serialized across different GEM objects. Replace the struct_mutex with a local omap_obj.lock or drop it altogether where not needed. Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen Signed-off-by: Tomi Valkeinen
