Parse and upload ACPI0007 (or PROCESSOR_TYPE) information to the\n hypervisor - aka P-states (cpufreq data).\n 2). Upload the the Cx state information (cpuidle data).\n 3). Inhibit CPU frequency scaling drivers from loading.\n\nThe reason for wanting to solve 1) and 2) is such that the Xen hypervisor\nis the only one that knows the CPU usage of different guests and can\nmake the proper decision of when to put CPUs and packages in proper states.\nUnfortunately the hypervisor has no support to parse ACPI DSDT tables, hence it\nneeds help from the initial domain to provide this information. The reason\nfor 3) is that we do not want the initial domain to change P-states while the\nhypervisor is doing it as well - it causes rather some funny cases of P-states\ntransitions.\n\nFor this to work, the driver parses the Power Management data and uploads said\ninformation to the Xen hypervisor. It also calls acpi_processor_notify_smm()\nto inhibit the other CPU frequency scaling drivers from being loaded.\n\nEverything revolves around the \u0027struct acpi_processor\u0027 structure which\ngets updated during the bootup cycle in different stages. At the startup, when\nthe ACPI parser starts, the C-state information is processed (processor_idle)\nand saved in said structure as \u0027power\u0027 element. Later on, the CPU frequency\nscaling driver (powernow-k8 or acpi_cpufreq), would call the the\nacpi_processor_* (processor_perflib functions) to parse P-states information\nand populate in the said structure the \u0027performance\u0027 element.\n\nSince we do not want the CPU frequency scaling drivers from loading\nwe have to call the acpi_processor_* functions to parse the P-states and\ncall \"acpi_processor_notify_smm\" to stop them from loading.\n\nThere is also one oddity in this driver which is that under Xen, the\nphysical online CPU count can be different from the virtual online CPU count.\nMeaning that the macros \u0027for_[online|possible]_cpu\u0027 would process only\nup to virtual online CPU count. We on the other hand want to process\nthe full amount of physical CPUs. For that, the driver checks if the ACPI IDs\ncount is different from the APIC ID count - which can happen if the user\nchoose to use dom0_max_vcpu argument. In such a case a backup of the PM\nstructure is used and uploaded to the hypervisor.\n\n[v1-v2: Initial RFC implementations that were posted]\n[v3: Changed the name to passthru suggested by Pasi Kärkkäinen \u003cpasik@iki.fi\u003e]\n[v4: Added vCPU !\u003d pCPU support - aka dom0_max_vcpus support]\n[v5: Cleaned up the driver, fix bug under Athlon XP]\n[v6: Changed the driver to a CPU frequency governor]\n[v7: Jan Beulich \u003cjbeulich@suse.com\u003e suggestion to make it a cpufreq scaling driver\n made me rework it as driver that inhibits cpufreq scaling driver]\n[v8: Per Jan\u0027s review comments, fixed up the driver]\n[v9: Allow to continue even if acpi_processor_preregister_perf.. fails]\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\n" }, { "commit": "d8414d3c157dc1f83e73c17447ba41fe5afa9d3d", "tree": "02195ebb0b1dd0b026b257825f02cddc3617df55", "parents": [ "243082e0d59f169a1fa502f51ee5a820889fae93" ], "author": { "name": "Bastian Blank", "email": "waldi@debian.org", "time": "Fri Dec 16 11:34:33 2011 -0500" }, "committer": { "name": "Konrad Rzeszutek Wilk", "email": "konrad.wilk@oracle.com", "time": "Fri Dec 16 13:29:31 2011 -0500" }, "message": "xen: Add privcmd device driver\n\nAccess to arbitrary hypercalls is currently provided via xenfs.

providing a\nmechanism to have contiguous pages for device drivers operations (say DMA\noperations).\n\nSpecifically, under Xen the Linux idea of pages is an illusion. It\nassumes that pages start at zero and go up to the available memory. To\nhelp with that, the Linux Xen MMU provides a lookup mechanism to\ntranslate the page frame numbers (PFN) to machine frame numbers (MFN)\nand vice-versa. The MFN are the \"real\" frame numbers. Furthermore\nmemory is not contiguous. Xen hypervisor stitches memory for guests\nfrom different pools, which means there is no guarantee that PFN\u003d\u003dMFN\nand PFN+1\u003d\u003dMFN+1. Lastly with Xen 4.0, pages (in debug mode) are\nallocated in descending order (high to low), meaning the guest might\nnever get any MFN\u0027s under the 4GB mark.\n\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nAcked-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nCc: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Albert Herranz \u003calbert_herranz@yahoo.es\u003e\nCc: Ian Campbell \u003cIan.Campbell@citrix.com\u003e\n" }, { "commit": "183d03cc4ff39e0f0d952c09aa96d0abfd6e0c3c", "tree": "75947fc4a9ac69e902663c9cb618993b7c656cff", "parents": [ "38e20b07efd541a959de367dc90a17f92ce2e8a6" ], "author": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Mon May 17 17:08:21 2010 +0100" }, "committer": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Thu Jul 22 16:46:09 2010 -0700" }, "message": "xen: Xen PCI platform device driver.\n\nAdd the xen pci platform device driver that is responsible\nfor initializing the grant table and xenbus in PV on HVM mode.\nFew changes to xenbus and grant table are necessary to allow the delayed\ninitialization in HVM mode.\nGrant table needs few additional modifications to work in HVM mode.\n\nThe Xen PCI platform device raises an irq every time an event has been\ndelivered to us. However these interrupts are only delivered to vcpu 0.\nThe Xen PCI platform interrupt handler calls xen_hvm_evtchn_do_upcall\nthat is a little wrapper around __xen_evtchn_do_upcall, the traditional\nXen upcall handler, the very same used with traditional PV guests.\n\nWhen running on HVM the event channel upcall is never called while in\nprogress because it is a normal Linux irq handler (and we cannot switch\nthe irq chip wholesale to the Xen PV ones as we are running QEMU and\nmight have passed in PCI devices), therefore we cannot be sure that\nevtchn_upcall_pending is 0 when returning.\nFor this reason if evtchn_upcall_pending is set by Xen we need to loop\nagain on the event channels set pending otherwise we might loose some\nevent channel
