Subject: [Xen-devel] [PATCH v3 0/9] Add hypervisor sysfs-like support
Date: Tue, 21 Jan 2020 09:43:21 +0100 [thread overview]
Message-ID: <20200121084330.18309-1-jgross@suse.com> (raw)
On the 2019 Xen developer summit there was agreement that the Xen
hypervisor should gain support for a hierarchical name-value store
similar to the Linux kernel's sysfs.
This is a first implementation of that idea adding the basic
functionality to hypervisor and tools side. The interface to any
user program making use of that "xen-hypfs" is a new library
"libxenhypfs" with a stable interface.
As a followup switching libxl to use the hypervisor file system for
runtime parameter modifications is possible. This would enable
removal of the XEN_SYSCTL_set_parameter sysctl operation.
Changes in V3:
- major rework, especially by supporting binary contents of entries
- added several new patches (1, 2, 7)
- full support of all runtime parameters
- support of writing entries (especially runtime parameters)
Changes in V2:
- all comments to V1 addressed
- added man-page for xenhypfs tool
- added runtime parameter read access for string parameters
Changes in V1:
- renamed xenfs ->xenhypfs
- added writable entries support at the interface level and in the
xenhypfs tool
- added runtime parameter read access (integer type only for now)
- added docs/misc/hypfs-paths.pandoc for path descriptions
Juergen Gross (9):
xen: add a generic way to include binary files as variables
xen: split parameter related definitions in own header file
docs: add feature document for Xen hypervisor sysfs-like support
xen: add basic hypervisor filesystem support
libs: add libxenhypfs
tools: add xenfs tool
xen: provide version information in hypfs
xen: add /buildinfo/config entry to hypervisor filesystem
xen: add runtime parameter access support to hypfs
