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 16857: XS_SET_TARGET
20 http://xenbits.xensource.com/xen-unstable.hg?rev/26fc953a89bb
22 New xenstore command to allow an arbitrary domain to inherit the
23 privileges of another (in addition to its own).
25 16856: XEN_DOMCTL_set_target
26 http://xenbits.xensource.com/xen-unstable.hg?rev/cff4c8a1aa28
28 New domctl command to give an arbitrary domain dom0-magnitude privileges
29 over an arbitrary other.
31 16725: XENFEAT_mmu_pt_update_reserve_ad
32 http://xenbits.xensource.com/xen-unstable.hg?rev/847bc9b19c48
34 New feature flag available via the version hypercall indicates whether the
35 Xen host supports MMU_PT_UPDATE_PRESERVE_AD for this guest.
37 16724: CPUID feature flag for MMU_PT_UPDATE_PRESERVE_AD hypercall
38 http://xenbits.xensource.com/xen-unstable.hg?rev/a66bdc82d8fa
40 The x86 CPUID_4000_0002_ECX[0] flag indicates whether the Xen host
41 supports MMU_PT_UPDATE_PRESERVE_AD for this guest.
44 http://xenbits.xensource.com/xen-unstable.hg?rev/fba4e7357744
46 A subcommand of the x86-only mmu_update() hypercall to allow batched
47 updates of pagetable entries, while atomically preserving the current
48 status of accessed and dirty bits in each entry.
50 Xen 3.2 release
51 ---------------
53 16592: XEN_DOMCTL_test_assign_device
54 http://xenbits.xensource.com/xen-unstable.hg?rev/ef83b50fc4a4
56 Test VT-d device assignability in xend. If VT-d is not enabled, or the
57 device is not exist, or the device has already been assigned to other
58 domain, it fails and quits the domain creation.
60 16549: GNTST_address_too_big
61 http://xenbits.xensource.com/xen-unstable.hg?rev/baf90ee3c1da
63 32-on-64 related additional error return.
65 16512: XEN_DOMCTL_set_opt_feature
66 http://xenbits.xensource.com/xen-unstable.hg?rev/1de4e5056394
68 Allows the domain builder to set optimization features for a guest. This
69 is currently only used by the IA64 domain builder to identify identity
70 mapped regions based on the guest_os_type specified in the domain config
71 file. Other architectures may extend this domctl to enable features
72 specific to their architecture.
74 16504: flush cache disk op
75 http://xenbits.xensource.com/xen-unstable.hg?rev/ebfb3b26010d
77 Adds a BLKIF_OP_FLUSH_DISKCACHE request. The backend is expected to ask
78 underlying storage to flush its cache upon receiving this request.
79 Backend advertises availability via 'feature-flush-cache' xenstore node.
80 Needed for correct behaviour of disk-cache-aware filesystems such as
81 ZFS.
83 16425: multicast notifications
84 http://xenbits.xensource.com/xen-unstable.hg?rev/d3041196ae69
87 operations to the networking driver, which it uses to request multicast
88 addresses it's interested in. Available if the backend has
89 'feature-multicast-control', requested by the frontend with
90 'request-multicast-control'. Used by Solaris: this avoids having to
91 always put the backend's underlying networking device into promiscuous
92 mode.
94 16402: gnttab page attributes
95 http://xenbits.xensource.com/xen-unstable.hg?rev/2e5d922b7ee3
97 Adds new grant tab flags for table entries.
99 Older changes are not recorded further.
