2024-06-03platform/x86: dell-smbios: Fix wrong token data in sysfsArmin Wolf1-56/+36
When reading token data from sysfs on my Inspiron 3505, the token locations and values are wrong. This happens because match_attribute() blindly assumes that all entries in da_tokens have an associated entry in token_attrs. This however is not true as soon as da_tokens[] contains zeroed token entries. Those entries are being skipped when initialising token_attrs, breaking the core assumption of match_attribute(). Fix this by defining an extra struct for each pair of token attributes and use container_of() to retrieve token information. Tested on a Dell Inspiron 3050.

Each TPMI power domain includes a group of CPUs. Several power management settings in this case applicable to a group of CPUs. There can be several power domains in a CPU package. So, provide interfaces for: - Get power domain id for a Linux CPU - Get mask of Linux CPUs in a power domain Hardware Punit uses different CPU numbering, which is not based on APIC (Advanced Programmable Interrupt Controller) CPU numbering. The Linux CPU numbering is based on APIC CPU numbering. Some PM features like Intel Speed Select, the CPU core mask provided by the hardware is based on the Punit CPU numbering. To use the core mask, this mask needs to be converted to a Linux CPUs mask. So, provide interfaces for: - Convert to a Linux CPU number from a Punit CPU number - Convert to a Punit CPU number from a Linux CPU number On each CPU online, MSR 0x54 is used to read the mapping and stores in a per cpu array.

2024-05-31platform/x86: ISST: Add model specific loading for common moduleSrinivas Pandruvada1-26/+37
SST common module is loaded when model specific or TPMI SST driver registers for services. There are model specific features used in SST common modules which are checked with a CPU model list. So, this module is model specific. There are some use cases where loading the common module independently only on the supported CPU models helps. The first use case is for preventing SST TPMI module loading if the model specific features are not implemented. The second use case for presenting information to user space when SST is used in OOB (Out of Band) mode. 1. With TPMI, SST interface is architectural. This means that no need to add new PCI device IDs for new CPU models. This means that there can be lag in adding CPU models for the model specific features in the common module. For example, before adding CPU model to GRANITERAPIDS_D to hpm_cpu_ids[], SST is still functional for some features and but will get/set wrong data for features like SST-CP. This is because IOCTL ISST_IF_GET_PHY_ID, will not give correct mapping for newer CPU models. So adding explicit model check during load time will prevent such cases. For unsupported CPU models, common driver will fail to load and hence dependent modules will not be loaded. 2. When the SST TPMI features are controlled by some OOB agent (not from OS interface), even if the CPU model is supported, there will be no user space interface available for tools as SST TPMI modules will not be loaded. User space interface is registered when TPMI modules call isst_if_cdev_register(). Even in this case user space orchestrator software needs to get power domain information to schedule workload and get/set turbo ratio limits. This information is exposed by the common module using IOCTLs ISST_IF_GET_PHY_ID and ISST_IF_MSR_COMMAND respectively. Since the user space MSR access can be locked, direct MSR access from the user space is not an option using /dev/cpu/*/msr. Converge all the existing model checks to one common place and use driver data to differentiate. On successful model check call isst_misc_reg().

properties from cmdline On x86/ACPI platforms touchscreens mostly just work without needing any device/model specific configuration. But in some cases (mostly with Silead and Goodix touchscreens) it is still necessary to manually specify various touchscreen-properties on a per model basis. touchscreen_dmi is a special place for DMI quirks for this, but it can be challenging for users to figure out the right property values, especially for Silead touchscreens where non of these can be read back from the touchscreen-controller. ATM users can only test touchscreen properties by editing touchscreen_dmi.c and then building a completely new kernel which makes it unnecessary difficult for users to test and submit properties when necessary for their laptop / tablet model. Add support for specifying properties on the kernel commandline to allow users to easily figure out the right settings. See the added documentation in kernel-parameters.txt for the commandline syntax.
