2023-07-24drm/omapdrm: Set VM flags in GEM-object mmap functionThomas Zimmermann4-38/+8
Use the mmap callback in struct drm_gem_object_funcs to set the VM flags. Replace a number of mmap helpers in omapdrm with their GEM helper counterparts. Generate DRM's file-operations instance with GEM's DEFINE_DRM_GEM_FOPS. The omapdrm driver uses DRM's drm_gem_mmap() helper to prepare the VMA structure. It then modifies the resulting VMA state in its own helper omap_gem_mmap_obj(). The patch improves this by setting up the VMA in the mmap callback in drm_gem_object_funcs, which is called from within drm_gem_mmap(). Omapdrm's omap_gem_mmap() and omap_gem_mmap() can then be removed from the driver. A call to drm_gem_mmap() is sufficient for the mmap operation. Finally, with the omap functions gone, the drivers file_ops in omapdriver_fops can be generated with DEFINE_DRM_GEM_FOPS, which sets DRM's default helpers. v2: * detailed commit message (Javier) * do not set VM_PFNMAP Signed-off-by: Thomas Zimmermann <[email protected]> Reviewed-by: Javier Martinez Canillas <[email protected]> Acked-by: Maxime Ripard <[email protected]> Cc: Tomi Valkeinen <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2023-07-24drm: Remove flag FBINFO_DEFAULT from fbdev emulationThomas Zimmermann4-4/+2
The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by framebuffer_alloc(). So do not set it. Flags should signal differences from the default values. After cleaning up all occurrences of FBINFO_DEFAULT, the token will be removed. v2: * fix commit message (Miguel) Signed-off-by: Thomas Zimmermann <[email protected]> Acked-by: Sam Ravnborg <[email protected]> Cc: Patrik Jakobsson <[email protected]> Cc: Alex Deucher <[email protected]> Cc: "Christian König" <[email protected]> Cc: "Pan, Xinhui" <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2023-07-24drm/managed: Clean up GFP_ flag usage in drmm_kmalloc()Dan Carpenter1-1/+1
This code is not using the correct gfp flags which were passed in. However, this does not affect runtime because kstrdup_const() is a no-op in this context. (It just returns the "kmalloc" string literal without doing an allocation.)
