      xen/acpi: Fix Kconfig dependency on CPU_FREQ · df7a3ee2
      Konrad Rzeszutek Wilk authored
      The functions: "acpi_processor_*" sound like they depend on CONFIG_ACPI_PROCESSOR
      but in reality they are exposed when CONFIG_CPU_FREQ=[y|m]. As such
      update the Kconfig to have this dependency and fix compile issues:

      xen: initialize platform-pci even if xen_emul_unplug=never · b9136d20
      Igor Mammedov authored
      When xen_emul_unplug=never is specified on kernel command line
      reading files from /sys/hypervisor is broken (returns -EBUSY).
      It is caused by xen_bus dependency on platform-pci and
      platform-pci isn't initialized when xen_emul_unplug=never is
      Fix it by allowing platform-pci to ignore xen_emul_unplug=never,
      and do not intialize xen_[blk|net]front instead.

      xen/acpi-processor: C and P-state driver that uploads said data to hypervisor. · 59a56802
      Konrad Rzeszutek Wilk authored
      This driver solves three problems:
       1). Parse and upload ACPI0007 (or PROCESSOR_TYPE) information to the
           hypervisor - aka P-states (cpufreq data).
       2). Upload the the Cx state information (cpuidle data).
       3). Inhibit CPU frequency scaling drivers from loading.
      The reason for wanting to solve 1) and 2) is such that the Xen hypervisor
      is the only one that knows the CPU usage of different guests and can
      make the proper decision of when to put CPUs and packages in proper states.
      Unfortunately the hypervisor has no support to parse ACPI DSDT tables, hence it
      needs help from the initial domain to provide this information. The reason
      for 3) is that we do not want the initial domain to change P-states while the
      hypervisor is doing it as well - it causes rather some funny cases of P-states
      For this to work, the driver parses the Power Management data and uploads said
      information to the Xen hypervisor. It also calls acpi_processor_notify_smm()
      to inhibit the other CPU frequency scaling drivers from being loaded.
      Everything revolves around the 'struct acpi_processor' structure which
      gets updated during the bootup cycle in different stages. At the startup, when
      the ACPI parser starts, the C-state information is processed (processor_idle)
      and saved in said structure as 'power' element. Later on, the CPU frequency
      scaling driver (powernow-k8 or acpi_cpufreq), would call the the
      acpi_processor_* (processor_perflib functions) to parse P-states information
      and populate in the said structure the 'performance' element.
      Since we do not want the CPU frequency scaling drivers from loading
      we have to call the acpi_processor_* functions to parse the P-states and
      call "acpi_processor_notify_smm" to stop them from loading.
      There is also one oddity in this driver which is that under Xen, the
      physical online CPU count can be different from the virtual online CPU count.
      Meaning that the macros 'for_[online|possible]_cpu' would process only
      up to virtual online CPU count. We on the other hand want to process
      the full amount of physical CPUs. For that, the driver checks if the ACPI IDs
      count is different from the APIC ID count - which can happen if the user
      choose to use dom0_max_vcpu argument. In such a case a backup of the PM
      structure is used and uploaded to the hypervisor.

      xen/enlighten: Expose MWAIT and MWAIT_LEAF if hypervisor OKs it. · 73c154c6
      Konrad Rzeszutek Wilk authored
      For the hypervisor to take advantage of the MWAIT support it needs
      to extract from the ACPI _CST the register address. But the
      hypervisor does not have the support to parse DSDT so it relies on
      the initial domain (dom0) to parse the ACPI Power Management information
      and push it up to the hypervisor. The pushing of the data is done
      by the processor_harveset_xen module which parses the information that
      the ACPI parser has graciously exposed in 'struct acpi_processor'.
      For the ACPI parser to also expose the Cx states for MWAIT, we need
      to expose the MWAIT capability (leaf 1). Furthermore we also need to
      expose the MWAIT_LEAF capability (leaf 5) for cstate.c to properly
      The hypervisor could expose these flags when it traps the XEN_EMULATE_PREFIX
      operations, but it can't do it since it needs to be backwards compatible.
      Instead we choose to use the native CPUID to figure out if the MWAIT
      capability exists and use the XEN_SET_PDC query hypercall to figure out
      if the hypervisor wants us to expose the MWAIT_LEAF capability or not.
      Note: The XEN_SET_PDC query was implemented in c/s 23783:
      "ACPI: add _PDC input override mechanism".
      With this in place, instead of
       C3 ACPI IOPORT 415
      we get now
      Note: The cpu_idle which would be calling the mwait variants for idling
      never gets set b/c we set the default pm_idle to be the hypercall variant.

      We needed that call in the past to force the kernel to use

      We must register the CPU subsystem, so panic if this fails.
