drm/{i915,xe}/fbdev: add intel_fbdev_fb_pitch_align()

2025-10-24T08:31:43+00:00

For reasons still unknown, xe appears to require a stride alignment of XE_PAGE_SIZE, and using 64 leads to sporadic failures. Go back to having separate stride alignment for i915 and xe, until the issue is root caused. v2: Add FIXME comment, reference issue with Link (Ville) Cc: Ville Syrjälä Cc: Jouni Högander Cc: Maarten Lankhorst Link: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/6220 Fixes: 4a36b339a14a ("drm/xe/fbdev: use the same 64-byte stride alignment as i915") Reviewed-by: Ville Syrjälä Link: https://lore.kernel.org/r/ae51d1e224048bdc87bf7a56d8f5ebd0fbb6a383.1756931441.git.jani.nikula@intel.com Signed-off-by: Jani Nikula Link: https://lore.kernel.org/r/20251022161054.708388-1-jani.nikula@intel.com

drm/{i915, xe}/fbdev: pass struct drm_device to intel_fbdev_fb_fill_info()

2025-09-19T06:32:36+00:00

This code is in fact driver core rather than display specific. Pass struct drm_device instead of struct intel_display. Reviewed-by: Ville Syrjälä Link: https://lore.kernel.org/r/1f633154f5f3106f55d7525a711bf347f5635ea7.1758184771.git.jani.nikula@intel.com Signed-off-by: Jani Nikula

drm/{i915,xe}/fbdev: deduplicate fbdev creation

With the bo creation helper in place, we can lift intel_framebuffer_create() part to common code. Reviewed-by: Ville Syrjälä Link: https://lore.kernel.org/r/7289deac730a877ab1bfcc467f9d063fdccf3930.1758184771.git.jani.nikula@intel.com Signed-off-by: Jani Nikula

drm/{i915, xe}/fbdev: add intel_fbdev_fb_bo_destroy()

2025-09-19T06:32:36+00:00

i915 and xe do different things on the failure path; i915 calls drm_gem_object_put() while xe calls xe_bo_unpin_map_no_vm().
