2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds-2/+1
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds-3/+3
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-6/+5
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>

2025-12-01drm/ast: Wrap cursor framebuffer access in drm_gem_fb_begin/end_cpu_access()Thomas Zimmermann-31/+43
Call drm_gem_fb_begin_cpu_access() and drm_gem_fb_end_cpu_access() around cursor image updates. Imported buffers might have to be synchronized for CPU access before they can be used. Ignore errors from drm_gem_fb_begin_cpu_access(). These errors can often be transitory. The cursor image will be updated on the next frame. Meanwhile display a white square where the cursor would be.

Copy the ARGB4444 cursor buffer to system memory if it is located in I/O memory. While this cannot happen with ast's native GEM objects, an imported buffer object might be on the external device's I/O memory.

2025-12-01drm/ast: Move cursor format conversion into helper functionThomas Zimmermann-23/+39
Move the format conversion of the cursor framebuffer into the new helper ast_cursor_plane_get_argb4444(). It returns a buffer in system memory, which the atomic_update handler copies to video memory. The returned buffer is either the GEM buffer itself, or a temporary copy within the plane in ARGB4444 format. As a small change, list supported formats explicitly in the switch statement. Do not assume ARGB8888 input by default. The cursor framebuffer knows its format, so should we.

In the atomic update callback, ast should call drm_gem_fb_begin_cpu_access() to make sure it can read the framebuffer from the CPU, otherwise the data might not be there due to cache, and synchronization.

2025-10-15drm/ast: Blank with VGACR17 sync enable, always clear VGACRB6 sync offThomas Zimmermann-8/+11
Blank the display by disabling sync pulses with VGACR17<7>. Unblank by reenabling them. This VGA setting should be supported by all Aspeed hardware. Ast currently blanks via sync-off bits in VGACRB6. Not all BMCs handle VGACRB6 correctly. After disabling sync during a reboot, some BMCs do not reenable it after the soft reset. The display output remains dark. When the display is off during boot, some BMCs set the sync-off bits in VGACRB6, so the display remains dark. Observed with Blackbird AST2500 BMCs. Clearing the sync-off bits unconditionally fixes these issues. Also do not modify VGASR1's SD bit for blanking, as it only disables GPU access to video memory. v2: - init vgacrb6 correctly (Jocelyn) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Fixes: ce3d99c83495 ("drm: Call drm_atomic_helper_shutdown() at shutdown time for misc drivers") Tested-by: Nick Bowler <nbowler@draconx.ca> Reported-by: Nick Bowler <nbowler@draconx.ca> Closes: https://lore.kernel.org/dri-devel/wpwd7rit6t4mnu6kdqbtsnk5bhftgslio6e2jgkz6kgw6cuvvr@xbfswsczfqsi/ Cc: Douglas Anderson <dianders@chromium.org> Cc: Dave Airlie <airlied@redhat.com> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Jocelyn Falempe <jfalempe@redhat.com> Cc: dri-devel@lists.freedesktop.org Cc: <stable@vger.kernel.org> # v6.7+ Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Link: https://lore.kernel.org/r/20251014084743.18242-1-tzimmermann@suse.de
