2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2026-01-12drm/xe/gsc: Make GSC FW load optional for newer platformsDaniele Ceraolo Spurio
On newer platforms GSC FW is only required for content protection features, so the core driver features work perfectly fine without it (and we did in fact not enable it to start with on PTL). Therefore, we can selectively enable the GSC only if the FW is found on disk, without failing if it is not found. Note that this means that the FW can now be enabled (i.e., we're looking for it) but not available (i.e., we haven't found it), so checks on FW support should use the latter state to decide whether to go on or not. As part of the rework, the message for FW not found has been cleaned up to be more readable. While at it, drop the comment about xe_uc_fw_init() since the code has been reworked and the statement no longer applies.

Since intel_gmch.c hasn't been part of xe, use a dummy function relocated from xe_display_misc.c, with #ifdef. This is purely to keep this change non-functional. This allows us to remove soc/intel_gmch.[ch] from i915, compat soc/intel_gmch.h from xe, and xe_display_misc.c from xe.

Add an irq parent driver interface for the .enabled and .synchronize calls.

2025-11-19drm/{i915, xe}/display: duplicate gen2 irq/error init/reset in display irqJani Nikula
Duplicate gen2_irq_reset(), gen2_assert_iir_is_zero(), gen2_irq_init(), gen2_error_reset(), and gen2_error_init() in intel_display_irq.c. This allows us to drop the duplicates from xe, and prepares for future cleanups. Although duplication is undesirable in general, in this case the local duplicates lead to a cleaner end result. There's a slight wrinkle in gen2_assert_iir_is_zero(). We need to use non-device based logging until we pass in struct intel_display in a separate change. v2: - Keep xe compat stuff due to series reorder and rebase - Keep the WARN as regular WARN - Rename the functions in the same go Suggested-by: Ville Syrjala <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patch.msgid.link/296d74731cce57ab7534c57969d3146294adda57.1763370931.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2025-11-07drm/i915/frontbuffer: Fix intel_frontbuffer lifetime handlingVille Syrjälä
The current attempted split between xe/i915 vs. display for intel_frontbuffer is a mess: - the i915 rcu leaks through the interface to the display side - the obj->frontbuffer write-side is now protected by a display specific spinlock even though the actual obj->framebuffer pointer lives in a i915 specific structure - the kref is getting poked directly from both sides - i915_active is still on the display side Clean up the mess by moving everything about the frontbuffer lifetime management to the i915/xe side: - the rcu usage is now completely contained in i915 - frontbuffer_lock is moved into i915 - kref is on the i915/xe side (xe needs the refcount as well due to intel_frontbuffer_queue_flush()->intel_frontbuffer_ref()) - the bo (and its refcounting) is no longer on the display side - i915_active is contained in i915 I was pondering whether we could do this in some kind of smaller steps, and perhaps we could, but it would probably have to start with a bunch of reverts (which for sure won't go cleanly anymore). So not convinced it's worth the hassle.

2025-11-03drm/{i915, xe}/display: pass parent interface to display probeJani Nikula
Let's gradually start calling i915 and xe parent, or core, drivers from display via function pointers passed at display probe. Going forward, the struct intel_display_parent_interface is expected to include const pointers to sub-structs by functionality, for example: struct intel_display_rpm { struct ref_tracker *(*get)(struct drm_device *drm); /* ... */ }; struct intel_display_parent_interface { /* ... */ const struct intel_display_rpm *rpm; }; This is a baby step towards not building display as part of both i915 and xe drivers, but rather making it an independent driver interfacing with the two. v3: useless include additions dropped v2: unrelated include removal dropped Cc: Jouni Högander <jouni.hogander@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Link: https://patch.msgid.link/20251030202836.1815680-2-jouni.hogander@intel.com
