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 16718: MMU_PT_UPDATE_PRESERVE_AD
20 http://xenbits.xensource.com/xen-unstable.hg?rev/fba4e7357744
22 A subcommand of the x86-only mmu_update() hypercall to allow batched
23 updates of pagetable entries, while atomically preserving the current
24 status of accessed and dirty bits in each entry.
26 Xen 3.2 release
27 ---------------
29 16592: XEN_DOMCTL_test_assign_device
30 http://xenbits.xensource.com/xen-unstable.hg?rev/ef83b50fc4a4
32 Test VT-d device assignability in xend. If VT-d is not enabled, or the
33 device is not exist, or the device has already been assigned to other
34 domain, it fails and quits the domain creation.
36 16549: GNTST_address_too_big
37 http://xenbits.xensource.com/xen-unstable.hg?rev/baf90ee3c1da
39 32-on-64 related additional error return.
41 16512: XEN_DOMCTL_set_opt_feature
42 http://xenbits.xensource.com/xen-unstable.hg?rev/1de4e5056394
44 Allows the domain builder to set optimization features for a guest. This
45 is currently only used by the IA64 domain builder to identify identity
46 mapped regions based on the guest_os_type specified in the domain config
47 file. Other architectures may extend this domctl to enable features
48 specific to their architecture.
50 16504: flush cache disk op
51 http://xenbits.xensource.com/xen-unstable.hg?rev/ebfb3b26010d
53 Adds a BLKIF_OP_FLUSH_DISKCACHE request. The backend is expected to ask
54 underlying storage to flush its cache upon receiving this request.
55 Backend advertises availability via 'feature-flush-cache' xenstore node.
56 Needed for correct behaviour of disk-cache-aware filesystems such as
57 ZFS.
59 16425: multicast notifications
60 http://xenbits.xensource.com/xen-unstable.hg?rev/d3041196ae69
62 Adds XEN_NETIF_EXTRA_TYPE_MCAST_ADD and XEN_NETIF_EXTRA_TYPE_MCAST_DEL
63 operations to the networking driver, which it uses to request multicast
64 addresses it's interested in. Available if the backend has
65 'feature-multicast-control', requested by the frontend with
66 'request-multicast-control'. Used by Solaris: this avoids having to
67 always put the backend's underlying networking device into promiscuous
68 mode.
70 16402: gnttab page attributes
71 http://xenbits.xensource.com/xen-unstable.hg?rev/2e5d922b7ee3
73 Adds new grant tab flags for table entries.
75 Older changes are not recorded further.
