drm/i915/fbdev: print info about stolen memory preference for fbdev

2026-02-25T12:35:28+00:00

If stolen memory cannot be allocated for the fbdev because of the preference for fbc, have an info about that in the log. v2: log text changed Signed-off-by: Vinod Govindapillai Reviewed-by: Uma Shankar Acked-by: Mika Kahola Link: https://patch.msgid.link/20260220170908.201422-7-vinod.govindapillai@intel.com

drm/i915/fbdev: Extract intel_fbdev_fb_prefer_stolen()

2026-02-25T12:35:28+00:00

Consolidate the "should we allocate fbdev fb in stolen?" check into a helper function. Makes it easier to change the heuristics without having to change so many places. v2: rebase related changes and consolidate all the prefer stolen conditions into a single function (Vinod) v3: avoid including intel_display_core.h (Jani) Signed-off-by: Ville Syrjälä Signed-off-by: Vinod Govindapillai Reviewed-by: Uma Shankar Acked-by: Mika Kahola Link: https://patch.msgid.link/20260220170908.201422-4-vinod.govindapillai@intel.com

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/{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/fbdev: drop dependency on display in i915 specific code

This code is in fact i915 driver core rather than display specific. Stop using struct intel_display, and drop the dependency on display headers.
