2023-03-20platform/x86/intel: vsec: Fix a memory leak in intel_vsec_add_auxDongliang Mu
The first error handling code in intel_vsec_add_aux misses the deallocation of intel_vsec_dev->resource. Fix this by adding kfree(intel_vsec_dev->resource) in the error handling code.

2023-02-10platform/x86/intel/vsec: Use mutex for ida_alloc() and ida_free()Srinivas Pandruvada
ID alloc and free functions don't have in built protection for parallel invocation of ida_alloc() and ida_free(). With the current flow in the vsec driver, there is no such scenario. But add mutex protection for potential future changes.

2023-02-06platform/x86/intel/vsec: Enhance and Export intel_vsec_add_aux()Srinivas Pandruvada
Remove static for intel_vsec_add_aux() and export this interface so that it can be used by other vsec related modules. This driver creates aux devices by parsing PCI-VSEC, which allows individual drivers to load on those devices. Those driver may further create more devices on aux bus by parsing the PCI MMIO region. For example, TPMI (Topology Aware Register and PM Capsule Interface) creates device nodes for power management features by parsing MMIO region. When TPMI driver creates devices, it can reuse existing function intel_vsec_add_aux() to create aux devices with TPMI device as the parent.

2022-02-14platform/x86: Add Intel Software Defined Silicon driverDavid E. Box
Intel Software Defined Silicon (SDSi) is a post manufacturing mechanism for activating additional silicon features. Features are enabled through a license activation process. The SDSi driver provides a per socket, sysfs attribute interface for applications to perform 3 main provisioning functions: 1. Provision an Authentication Key Certificate (AKC), a key written to internal NVRAM that is used to authenticate a capability specific activation payload. 2. Provision a Capability Activation Payload (CAP), a token authenticated using the AKC and applied to the CPU configuration to activate a new feature. 3. Read the SDSi State Certificate, containing the CPU configuration state. The operations perform function specific mailbox commands that forward the requests to SDSi hardware to perform authentication of the payloads and enable the silicon configuration (to be made available after power cycling). The SDSi device itself is enumerated as an auxiliary device from the intel_vsec driver and as such has a build dependency on CONFIG_INTEL_VSEC.

2021-12-22platform/x86/intel: Move intel_pmt from MFD to Auxiliary BusDavid E. Box
Intel Platform Monitoring Technology (PMT) support is indicated by presence of an Intel defined PCIe Designated Vendor Specific Extended Capabilities (DVSEC) structure with a PMT specific ID. The current MFD implementation creates child devices for each PMT feature, currently telemetry, watcher, and crashlog. However DVSEC structures may also be used by Intel to indicate support for other features. The Out Of Band Management Services Module (OOBMSM) uses DVSEC to enumerate several features, including PMT. In order to support them it is necessary to modify the intel_pmt driver to handle the creation of the child devices more generically. To that end, modify the driver to create child devices for any VSEC/DVSEC features on supported devices (indicated by PCI ID). Additionally, move the implementation from MFD to the Auxiliary bus. VSEC/DVSEC features are really multifunctional PCI devices, not platform devices as MFD was designed for. Auxiliary bus gives more flexibility by allowing the definition of custom structures that can be shared between associated auxiliary devices and the parent device. Also, rename the driver from intel_pmt to intel_vsec to better reflect the purpose. This series also removes the current runtime pm support which was not complete to begin with. None of the current devices require runtime pm. However the support will be replaced when a device is added that requires it.
