treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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

vga_switcheroo: Use pci_is_display()

2025-07-17T20:30:13+00:00

The inline pci_is_display() helper does the same thing. Use it. Suggested-by: Bjorn Helgaas Signed-off-by: Mario Limonciello Signed-off-by: Bjorn Helgaas Reviewed-by: Daniel Dadap Reviewed-by: Simona Vetter Link: https://patch.msgid.link/20250717173812.3633478-4-superm1@kernel.org

drm: Do delayed switcheroo in drm_lastclose()

2024-08-13T14:21:07+00:00

Amdgpu and nouveau call vga_switcheroo_process_delayed_switch() from their lastclose callbacks. Call it from drm_lastclose(), so that the driver functions can finally be removed. Only PCI devices with enabled switcheroo do the delayed switching. The call has no effect on other hardware. v2: - move change to drm_lastclose() (Sima) - update docs for vga_switcheroo_process_delayed_switch() Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter Reviewed-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20240812083000.337744-2-tzimmermann@suse.de

PCI/VGA: Move vgaarb to drivers/pci

2022-03-10T00:30:46+00:00

The VGA arbiter is really PCI-specific and doesn't depend on any GPU things. Move it to the PCI subsystem. Note that misc_init() must be called before vga_arb_device_init(). These are both subsys_initcalls, so this ordering depends on the link order, which is determined by drivers/Makefile: obj-y += pci/ obj-y += char/ <-- misc_init() obj-y += gpu/ <-- vga_arb_device_init() (before this commit) The drivers/pci/ subsys_initcalls are called *before* misc_init(), so convert vga_arb_device_init() to subsys_initcall_sync(), which is called after *all* subsys_initcalls.

vgaarb: don't pass a cookie to vga_client_register

The VGA arbitration is entirely based on pci_dev structures, so just pass that back to the set_vga_decode callback. Signed-off-by: Christoph Hellwig Link: https://patchwork.freedesktop.org/patch/msgid/20210716061634.2446357-8-hch@lst.de Acked-by: Christian König Signed-off-by: Christian König
