soc: qcom: pd-mapper: Add support for Eliza

2026-03-30T13:37:27+00:00

Add support for the Qualcomm Eliza SoC to the protection domain mapper. It has the same exact protection domain configuration as SM8550 SoC, so reuse that.

soc: qcom: pd-mapper: Add support for Glymur and Mahua

2026-03-26T02:45:17+00:00

Add Protection Domains for Qualcomm Glymur and Mahua SoC which have both ADSP and CDSP. Adding this entry to the kernel will avoid the need for userspace to provide this service.

Add support for the Qualcomm Milos SoC to the protection domain mapper. Milos shares the same protection domain configuration as SM8550, so reuse the existing SM8550 domain data.

soc: qcom: pdr: Use the unified QMI service ID instead of defining it locally

Instead of defining a local macro with a custom name for the QMI service identifier, use the one provided in qmi.h and remove the locally defined macro.

A few lines of code are removed by using the global non-NULL of_root pointer to access the root device tree node instead of its recalculation.

2026-03-09T23:09:36+00:00

Add the QCS615 domain table to the in-kernel pd-mapper so that audio subsystems no longer rely on the userspace pd-mapper daemon. This enables proper initialization of ADSP and CDSP domains directly from the kernel.

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
