1 This file contains a list of changes and additions to the API/ABI that
2 might affect cross-OS compatibility or otherwise impact OS
3 implementations, in particular any changes to hypervisor interfaces and
4 the inter-domain protocols. When making such a change you are expected
5 to add it here (bonus points for a link to fuller documentation). New
6 entries should be part of the patch making the change (so the history of
7 this file will give the relevant changeset), added to the top of the
8 file, and in a format like:

16 Xen 3.3 release
17 ---------------
19 17524: Add DOMCTL_set_cpuid to configure guest CPUID on x86 systems.
20 http://xenbits.xensource.com/xen-unstable.hg?rev/18727843db60
22 17336: Add platform capabilities field to XEN_SYSCTL_physinfo
23 http://xenbits.xensource.com/xen-unstable.hg?rev/250606290439
25 17289: PV framebuffer dynamic resolution facility
26 http://xenbits.xensource.com/xen-unstable.hg?rev/d97e61001d81
28 Guest may send XENFB_TYPE_RESIZE if feature-resize=1 in
29 xenstore of the backend VNC server. VNC server code sets
30 feature-resize if it can handle the resize request.
32 16857: XS_SET_TARGET
33 http://xenbits.xensource.com/xen-unstable.hg?rev/26fc953a89bb
35 New xenstore command to allow an arbitrary domain to inherit the
36 privileges of another (in addition to its own).
38 16856: XEN_DOMCTL_set_target
39 http://xenbits.xensource.com/xen-unstable.hg?rev/cff4c8a1aa28
41 New domctl command to give an arbitrary domain dom0-magnitude privileges
42 over an arbitrary other.
44 16725: XENFEAT_mmu_pt_update_reserve_ad
45 http://xenbits.xensource.com/xen-unstable.hg?rev/847bc9b19c48
47 New feature flag available via the version hypercall indicates whether the
48 Xen host supports MMU_PT_UPDATE_PRESERVE_AD for this guest.
50 16724: CPUID feature flag for MMU_PT_UPDATE_PRESERVE_AD hypercall
51 http://xenbits.xensource.com/xen-unstable.hg?rev/a66bdc82d8fa
53 The x86 CPUID_4000_0002_ECX[0] flag indicates whether the Xen host
54 supports MMU_PT_UPDATE_PRESERVE_AD for this guest.
57 http://xenbits.xensource.com/xen-unstable.hg?rev/fba4e7357744
59 A subcommand of the x86-only mmu_update() hypercall to allow batched
60 updates of pagetable entries, while atomically preserving the current
61 status of accessed and dirty bits in each entry.
63 Xen 3.2 release
64 ---------------
66 16592: XEN_DOMCTL_test_assign_device
67 http://xenbits.xensource.com/xen-unstable.hg?rev/ef83b50fc4a4
69 Test VT-d device assignability in xend. If VT-d is not enabled, or the
70 device is not exist, or the device has already been assigned to other
71 domain, it fails and quits the domain creation.
73 16549: GNTST_address_too_big
74 http://xenbits.xensource.com/xen-unstable.hg?rev/baf90ee3c1da
76 32-on-64 related additional error return.
78 16512: XEN_DOMCTL_set_opt_feature
79 http://xenbits.xensource.com/xen-unstable.hg?rev/1de4e5056394
81 Allows the domain builder to set optimization features for a guest. This
82 is currently only used by the IA64 domain builder to identify identity
83 mapped regions based on the guest_os_type specified in the domain config
84 file. Other architectures may extend this domctl to enable features
85 specific to their architecture.
87 16504: flush cache disk op
88 http://xenbits.xensource.com/xen-unstable.hg?rev/ebfb3b26010d
90 Adds a BLKIF_OP_FLUSH_DISKCACHE request. The backend is expected to ask
91 underlying storage to flush its cache upon receiving this request.
92 Backend advertises availability via 'feature-flush-cache' xenstore node.
93 Needed for correct behaviour of disk-cache-aware filesystems such as
94 ZFS.
96 16425: multicast notifications
97 http://xenbits.xensource.com/xen-unstable.hg?rev/d3041196ae69
100 operations to the networking driver, which it uses to request multicast
101 addresses it's interested in. Available if the backend has
102 'feature-multicast-control', requested by the frontend with
103 'request-multicast-control'. Used by Solaris: this avoids having to
104 always put the backend's underlying networking device into promiscuous
105 mode.
107 16402: gnttab page attributes
108 http://xenbits.xensource.com/xen-unstable.hg?rev/2e5d922b7ee3
110 Adds new grant tab flags for table entries.
112 Older changes are not recorded further.
