* platform/x86/intel/ifs: Add stub driver for In-Field ScanTony Luck2022-05-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Cloud Service Providers that operate fleets of servers have reported [1] occasions where they can detect that a CPU has gone bad due to effects like electromigration, or isolated manufacturing defects. However, that detection method is A/B testing seemingly random application failures looking for a pattern. In-Field Scan (IFS) is a driver for a platform capability to load a crafted 'scan image' to run targeted low level diagnostics outside of the CPU's architectural error detection capabilities. Stub version of driver just does initial part of check for the IFS feature. MSR_IA32_CORE_CAPS must enumerate the presence of the MSR_INTEGRITY_CAPS MSR.

* platform/x86: Add Intel Software Defined Silicon driverDavid E. Box2022-02-141-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Now that there is only 1 c-file left of the intel_cht_int33fe code, move it to the intel directory instead of it having its own int33fe sub-directory. Note this also renames the module from intel_cht_int33fe_typec to intel_chtwc_int33fe, to better match the names of other PMIC related modules like the intel_chtdc_ti_pwrbtn module.

| * platform/x86/intel: Move intel_pmt from MFD to Auxiliary BusDavid E. Box2021-12-221-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | platform/x86/intel: Remove X86_PLATFORM_DRIVERS_INTELAndy Shevchenko2021-12-231-15/+0
|/ | | | | | | | | | | | | | | | | While introduction of this menu brings a nice view in the configuration tools, it brought more issues than solves, i.e. it prevents to locate files in the intel/ subfolder without touching non-related Kconfig dependencies elsewhere. Drop X86_PLATFORM_DRIVERS_INTEL altogether. Note, on x86 it's enabled by default and it's quite unlikely anybody wants to disable all of the modules in this submenu.
