platform/x86/intel/vsec: Switch exported helpers from pci_dev to device

2026-03-17T16:51:15Z

Preparatory refactor for ACPI-enumerated PMT endpoints. Several exported PMT/VSEC interfaces and structs carried struct pci_dev * even though callers only need a generic struct device. Move those to struct device * so the same APIs work for PCI and ACPI parents. Acked-by: Rodrigo Vivi Signed-off-by: David E.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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

platform/x86/intel/pmc: Enable substate residencies for multiple PMCs

2026-01-13T14:31:39Z

Enable substate residencies support for multiple PMCs. Previously substate residencies were shown only for the primary PMC. This change enables substate residencies for all available PMCs. The output of substate_residencies with this patch will be similar to this: pmc0 Substate Residency S0i2.0 0 S0i2.1 0 S0i2.2 0 pmc1 Substate Residency S0i2.0 0 S0i2.1 0 S0i2.2 0 pmc2 Substate Residency S0i2.0 0 Signed-off-by: Xi Pardee Link: https://patch.msgid.link/20260108223144.504267-4-xi.pardee@linux.intel.com Reviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen

platform/x86/intel/pmc: Move LPM mode attributes to PMC

2026-01-13T14:31:38Z

Move LPM modes attributes from the pmc_dev to the pmc structure. LPM modes are PMC-specific and should be stored within the pmc structure. After the change, LPM mode information will be retrieved and stored per PMC. The substate_requirements attribute in debugfs will display the requirements for each enabled LPM substate.

platform/x86:intel/pmc: Relocate lpm_req_guid to pmc_reg_map

2025-10-15T09:21:17Z

Relocate the lpm_req_guid field from pmc_info to pmc_reg_map. The previous implementation stored lpm_req_guid in pmc_info and relied on pmc_core_find_guid() to retrieve the correct GUID, which was unnecessary. Since lpm_req_guid is specific to PMC, pmc_reg_map is a more appropriate location for this information.
