Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

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

misc/mei: Allow building standalone for compile testing

2026-01-16T15:30:38+00:00

While this is not a particularly useful configuration, the MEI code should compile even when no drivers for a GPU containing a management engine are built.

misc/mei: Decouple ME interfaces from GPU drivers

2026-01-16T15:30:38+00:00

These are enumerated via an auxiliary bus, so there is no functional dependency between these drivers, therefore allow compiling MEI as builtin even when i915/xe are built as modules.

2024-01-31T00:19:59+00:00

Xe driver uses this component too, but current match function matches by i915 driver name. Remove dependency on i915 driver name in component_match function. Use PCI header information to match Intel graphics device.

mei: rework Kconfig dependencies

2023-12-15T16:02:15+00:00

The dependencies in the mei framework are inconsistent, with some symbols using 'select INTEL_MEI' to force it being enabled and others using 'depends on INTEL_MEI'. In general, one should not select user-visible symbols, so change all of these to normal dependencies, but change the default on INTEL_MEI to be enabled when building a kernel for an Intel CPU with ME or a generic x86 kernel. Having consistent dependencies makes the 'menuconfig' listing more readable by using proper indentation. A large if/endif block is just a simpler syntax than repeating the dependencies for each symbol.
