x86/cpu: Add a steppings field to struct x86_cpu_id

2022-10-07T07:16:54Z

commit e9d7144597b10ff13ff2264c059f7d4a7fbc89ac upstream. Intel uses the same family/model for several CPUs. Sometimes the stepping must be checked to tell them apart. On x86 there can be at most 16 steppings. Add a steppings bitmask to x86_cpu_id and a X86_MATCH_VENDOR_FAMILY_MODEL_STEPPING_FEATURE macro and support for matching against family/model/stepping.

x86/devicetable: Move x86 specific macro out of generic code

mod_devicetable: fix PHY module format

2019-12-31T15:41:16Z

[ Upstream commit d2ed49cf6c13e379c5819aa5ac20e1f9674ebc89 ] When a PHY is probed, if the top bit is set, we end up requesting a module with the string "mdio:-10101110000000100101000101010001" - the top bit is printed to a signed -1 value. This leads to the module not being loaded. Fix the module format string and the macro generating the values for it to ensure that we only print unsigned types and the top bit is always 0/1. We correctly end up with "mdio:10101110000000100101000101010001".

platform/x86: wmi: add context pointer field to struct wmi_device_id

2019-06-17T12:22:47Z

When using wmi_install_notify_handler() to initialize a WMI handler a data pointer can be supplied which will be passed on to the notification handler. No similar feature exist when handling WMI events via struct wmi_driver. Add a context field pointer to struct wmi_device_id and add a function find_guid_context() to retrieve that context pointer.
