mei: pxp: match against PCI_CLASS_DISPLAY_OTHER

2024-04-24T04:44:13Z

The ATS-M class is PCI_CLASS_DISPLAY_OTHER instead of PCI_CLASS_DISPLAY_VGA, so we need to match against that class as well. The matching is still restricted to Intel devices only.

mei: pxp: match without driver name

2024-01-31T00:19:59Z

Xe driver uses this component too, but current match function matches by i915 driver name. Remove dependency on i915 driver name in component_match function. Use PCI header information to match Intel graphics device.

mei: rework Kconfig dependencies

2023-12-15T16:02:15Z

The dependencies in the mei framework are inconsistent, with some symbols using 'select INTEL_MEI' to force it being enabled and others using 'depends on INTEL_MEI'. In general, one should not select user-visible symbols, so change all of these to normal dependencies, but change the default on INTEL_MEI to be enabled when building a kernel for an Intel CPU with ME or a generic x86 kernel. Having consistent dependencies makes the 'menuconfig' listing more readable by using proper indentation. A large if/endif block is just a simpler syntax than repeating the dependencies for each symbol.

mei: update mei-pxp's component interface with timeouts

2023-10-18T08:01:33Z

In debugging platform or firmware related MEI-PXP connection issues, having a timeout when clients (such as i915) calling into mei-pxp's send/receive functions have proven useful as opposed to blocking forever until the kernel triggers a watchdog panic (when platform issues are experienced). Update the mei-pxp component interface send and receive functions to take in timeouts.
