* tpmif: fix identifier prefixesJan Beulich2013-06-211-1/+1
| | | | | | | | | | The definitions here shouldn't use vtpm_ or VPTM_ as their prefixes, the interface should instead make use of tpmif_ and TPMIF_. This fixes a build failure after syncing the public headers to linux-2.6.18-xen.hg (where a struct vtpm_state already exists).

* mini-os/tpmback: Replace UUID field with opaque pointerDaniel De Graaf2013-04-121-2/+7
| | | | | | | | Instead of only recording the UUID field, which may not be of interest to all tpmback implementations, provide a user-settable opaque pointer associated with the tpmback instance. Signed-off-by: Daniel De Graaf <dgdegra@tycho.nsa.gov>
* mini-os/tpmback: set up callbacks before enumerationDaniel De Graaf2013-04-121-11/+1
| | | | | | | | | | | | The open/close callbacks in tpmback cannot be properly initalized in order to catch the initial enumeration events because init_tpmback clears the callbacks and then asynchronously starts the enumeration of existing tpmback devices. Fix this by passing the callbacks to init_tpmback so they can be installed before enumeration. This also removes the unused callbacks for suspend and resume.

* mini-os/tpm{back, front}: Change shared page ABIDaniel De Graaf2013-04-122-3/+5
| | | | | | | | | | | | | | | | | | | | | This changes the vTPM shared page ABI from a copy of the Xen network interface to a single-page interface that better reflects the expected behavior of a TPM: only a single request packet can be sent at any given time, and every packet sent generates a single response packet. This protocol change should also increase efficiency as it avoids mapping and unmapping grants when possible. The vtpm xenbus device now requires a feature-protocol-v2 node in xenstore to avoid conflicts with existing (xen-patched) kernels supporting the old interface. While the contents of the shared page have been defined to allow packets larger than a single page (actually 4088 bytes) by allowing the client to add extra grant references, the mapping of these extra references has not been implemented; a feature node in xenstore may be used in the future to indicate full support for the multi-page protocol. Most uses of the TPM should not require this feature. Signed-off-by: Daniel De Graaf <dgdegra@tycho.nsa.gov> Cc: Jan Beulich <JBeulich@suse.com>

| | | | | | | | | | | | | Various fixes to mini-os needed to build lwip 1.3.2: - Don't build the tests. - Add BSD-style endianness macros to endian.h. - free() is called via a function pointer so it needs to be a real function.

* mini-os: Notify shutdown through weak function call instead of wake queueSamuel Thibault2013-01-091-3/+0

* minios: add tpmfront, tpm_tis, and tpmback driversMatthew Fioravante2012-11-134-0/+278
| | | | | | | | | | | | | | | | | | | | This patch adds 3 new drivers to mini-os. tpmfront - paravirtualized tpm frontend driver tpmback - paravirtualized tpm backend driver tpm_tis - hardware tpm driver Unfortunately these drivers were derived from GPL licensed linux kernel drivers so they must carry the GPL license. However, since mini-os now supports conditional compilation, hopefully these drivers can be included into the xen tree and conditionally removed from non-gpl projects. By default they are disabled in the makefile.

* mini-os: make frontends and xenbus optionalDaniel De Graaf2012-02-092-0/+14
| | | | | | | | | | | | | | | | | This adds compile-time logic to disable certain frontends in mini-os: - pcifront is disabled by default, enabled for ioemu - blkfront, netfront, fbfront, kbdfront, consfront are enabled by default - xenbus is required for any frontend, and is enabled by default If all frontends and xenbus are disabled, mini-os will run without needing to communicate with xenstore, making it suitable to run the xenstore daemon. The console frontend is not required for the initial console, only consoles opened via openpt or ptmx.

* mini-os: use BSD sys/queue.h instead of Linux list.hIan Campbell2012-01-315-225/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latter is GPL which makes the whole of mini-os GPL rather than BSD as intended. In tree users are all GPL or GPL-compatible but we should fix this so that mini-os is BSD. Do so by using the same BSD sys/queue.h as we use in libxl. Tested with the builtin mini-os test app and qemu stubdomain, both of which appear to still function as expected. Move tools/libxl/external and the associated sed script to tools/include/xen-external to allow more sensible access from mini-os. Also add s/NULL/0/ in the sed script due to NULL not always being defined in stubdom code when mini-os/wait.h is included. As well as the obvious ABI changes there are a few API updates associated with the change: - struct rw_semaphore.wait_list is unused - remove_waiter needs to take the wait_queue_head The latter requires a qemu update, so there is also a QEMU_TAG update in this changeset. I sprinkled some extra-emacs local variables around the files I edited which didn't have them. I think this should be backported to the stable branches since external users of mini-os may have been mislead into thinking they could safely link mini-os against GPL-incompatible code.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes all the useless big endian stuff from the mini-os. Before there was an effort to support big endian for PV-guest. But the big endian support was never gotten into the common parts of the mini-os so it makes no sense to have this only in the ia64 specific sources.
