* libxc: add xc_domain_set_max_evtchn()David Vrabel2013-10-141-0/+11

* libxc: introduce xc_map_domain_meminfo (and xc_unmap_domain_meminfo)Dario Faggioli2013-09-131-0/+127
| | | | | | | | | | | | | And use it in xc_exchange_page(). This is basically because the following change need something really similar to the set of steps that are here abstracted in these two functions. Despite of the change in the interface and in the signature of some functions, this is pure code motion. No functional changes involved.

* libxc: introduce xc_domain_get_guest_width()Dario Faggioli2013-09-131-0/+16
| | | | | | | | | | | | | | As a wrapper to XEN_DOMCTL_get_address_size, and use it wherever the call was being issued directly via do_domctl(), saving quite some line of code. Actually, the function returns the guest width in bytes, rather than directly what XEN_DOMCTL_get_address_size provides (which is a number of bits), since that is what it is useful almost everywhere.

* hypervisor/xen/tools: Remove the XENMEM_get_oustanding_pages and provide the ↵Konrad Rzeszutek Wilk2013-05-141-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | data via xc_phys_info During the review of the patches it was noticed that there exists a race wherein the 'free_memory' value consists of information from two hypercalls. That is the XEN_SYSCTL_physinfo and XENMEM_get_outstanding_pages. The free memory the host has available for guest is the difference between the 'free_pages' (from XEN_SYSCTL_physinfo) and 'outstanding_pages'. As they are two hypercalls many things can happen in between the execution of them. This patch resolves this by eliminating the XENMEM_get_outstanding_pages hypercall and providing the free_pages and outstanding_pages information via the xc_phys_info structure. It also removes the XSM hooks and adds locking as needed.

* xc: export outstanding_pages value in xc_dominfo structure.Dan Magenheimer2013-04-161-0/+1
| | | | | | | | | | | | | | | | | | This patch provides the value of the currently outstanding pages claimed for a specific domain. This is a value that influences the global outstanding claims value (See patch: "xl: 'xl info' print outstanding claims if enabled") returned via xc_domain_get_outstanding_pages hypercall. This domain value decrements as the memory is populated for the guest and eventually reaches zero. This patch is neccessary for "xl: export 'outstanding_pages' value from xcinfo" patch.

* xc: use XENMEM_claim_pages hypercall during guest creation.Dan Magenheimer2013-04-161-0/+30
| | | | | | | | | | | | | | | | | | | | | | We add an extra parameter to the structures passed to the PV routine (arch_setup_meminit) and HVM routine (setup_guest) that determines whether the claim hypercall is to be done. The contents of the 'claim_enabled' is defined as an 'int' in case the hypercall expands in the future with extra flags (for example for per-NUMA allocation). For right now the proper values are: 0 to disable it or 1 to enable it. If the hypervisor does not support this function, the xc_domain_claim_pages and xc_domain_get_outstanding_pages will silently return 0 (and set errno to zero).

| | | | | | | | | | | | | | | | | | | | | | | At the sender xc_domain_save has a key point: 'to query the types of all the pages with xc_get_pfn_type_batch' 1) if broken page occur before the key point, migration will be fine since proper pfn_type and pfn number will be transferred to the target and then take appropriate action; 2) if broken page occur after the key point, whole system will crash and no need care migration any more; At the target Target will populates pages for guest. As for the case of broken page, we prefer to keep the type of the page for the sake of seamless migration. Target will set p2m as p2m_ram_broken for broken page. If guest access the broken page again it will kill itself as expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the wrappers for these hypercalls swallow partial success and return failure to the caller. In order to use these functions more widely instead of open-coding uses of XENMEM_* and xc_memory_op add variants which return the actual hypercall result. Therefore add the following functions: xc_domain_increase_reservation xc_domain_decrease_reservation xc_domain_populate_physmap and implement the existing semantics using these new functions as xc_domain_increase_reservation_exact xc_domain_decrease_reservation_exact xc_domain_populate_physmap_exact replacing the existing xc_domain_memory_* functions. Use these new functions to replace all open coded uses of XENMEM_increase_reservation, XENMEM_decrease_reservation and XENMEM_populate_physmap. Also rename xc_domain_memory_*_pod_target to xc_domain_*_pod_target for consistency. Temporarily add a compatibility macro for xc_domain_memory_populate_physmap to allow time for qemu to catch up.

* Replace tsc_native config option with tsc_mode config optionKeir Fraser2009-11-251-6/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (NOTE: pvrdtscp mode not finished yet, but all other modes have been tested so sooner seemed better than later to submit this fairly major patch so we can get more mileage on it before next release.) New tsc_mode config option supercedes tsc_native and offers a more intelligent default and an additional option for intelligent apps running on PV domains ("pvrdtscp"). For PV domains, default mode will determine if the initial host has a "safe"** TSC (meaning it is always synchronized across all physical CPUs). If so, all domains will execute all rdtsc instructions natively; if not, all domains will emulate all rdtsc instructions but providing the TSC hertz rate of the initial machine. After being restored or live-migrated, all PV domains will emulate all rdtsc instructions. Hence, this default mode guarantees correctness while providing native performance in most conditions. For PV domains, tsc_mode==1 will always emulate rdtsc and tsc_mode==2 will never emulate rdtsc. For tsc_mode==3, rdtsc will never be emulated, but information is provided through pvcpuid instructions and rdtscp instructions so that an app can obtain "safe" pvclock-like TSC information across save/restore and live migration. (Will be completed in a follow-on patch.) For HVM domains, the default mode and "always emulate" mode do the same as tsc_native==0; the other two modes do the same as tsc_native==1. (HVM domains since 3.4 have implemented a tsc_mode=default-like functionality, but also can preserve native TSC across save/restore and live-migration IFF the initial and target machines have a common TSC cycle rate.) ** All newer AMD machines, and Nehalem and future Intel machines have "Invariant TSC"; many newer Intel machines have "Constant TSC" and do not support deep-C sleep states; these and all single-processor machines are "safe".
