2013-04-22Add option to mlock qemu and guest memorySatoru Moriya1-0/+34
In certain scenario, latency induced by paging is significant and memory locking is needed. Also, in the scenario with untrusted guests, latency improvement due to mlock is desired.

2013-04-15tpm: reorganize headers and split hardware partPaolo Bonzini1-1/+1
The TPM subsystem does not have a full front-end/back-end separation. The sole available backend, tpm_passthrough, depends on the data structures of the sole available frontend, tpm_tis. However, we can at least try to split the user interface (tpm.c) from the implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h, which is shared between tpm_tis.c and tpm_passthrough.c; instead it moves more stuff to tpm_backend.h.

2013-04-04qemu-char: Call fe_claim / fe_release when not using qdev chr propertiesHans de Goede1-0/+1
chardev-frontends need to explictly check, increase and decrement the avail_connections "property" of the chardev when they are not using a qdev-chardev-property for the chardev. This fixes things like: qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \ -mon chardev=foo Working, where they should fail.

2013-03-12Add search path support for qemu data files.Gerd Hoffmann1-13/+23
This patch allows to specify multiple directories where qemu should look for data files. To implement that the behavior of the -L switch is slightly different now: Instead of replacing the data directory the path specified will be appended to the data directory list. So when specifiying -L multiple times all directories specified will be checked, in the order they are specified on the command line, instead of just the last one. Additionally the default paths are always appended to the directory data list. This allows to specify a incomplete directory (such as the seabios out/ directory) via -L. Anything not found there will be loaded from the default paths, so you don't have to create a symlink farm for all the rom blobs. For trouble-shooting a tracepoint has been added, logging which blob has been loaded from which location.

2013-03-12Add support for cancelling of a TPM commandStefan Berger1-0/+5
This patch adds support for cancelling an executing TPM command. In Linux for example a user can cancel a command through the TPM's sysfs 'cancel' entry using echo "1" > /sysfs/class/misc/tpm0/device/cancel This patch propagates the cancellation of a command inside a VM to the host TPM's sysfs entry. It also uses the possibility to cancel the command before QEMU VM shutdown or reboot, which helps in preventing QEMU from hanging while waiting for the completion of the command. To relieve higher layers or users from having to determine the TPM's cancel sysfs entry, the driver searches for the entry in well known locations.

2013-03-12Support for TPM command line optionsStefan Berger1-0/+37
This patch adds support for TPM command line options. The command line options supported here are ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id> -device tpm-tis,tpmdev=<id>,id=<other id> and ./qemu-... -tpmdev help where the latter works similar to -soundhw help and shows a list of available TPM backends (for example 'passthrough'). Using the type parameter, the backend is chosen, i.e., 'passthrough' for the passthrough driver. The interpretation of the other parameters along with determining whether enough parameters were provided is pushed into the backend driver, which needs to implement the interface function 'create' and return a TPMDriverOpts structure if the VM can be started or 'NULL' if not enough or bad parameters were provided. Monitor support for 'info tpm' has been added. It for example prints the following: (qemu) info tpm TPM devices: tpm0: model=tpm-tis \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Reviewed-by: Joel Schopp <jschopp@linux.vnet.ibm.com> Message-id: 1361987275-26289-2-git-send-email-stefanb@linux.vnet.ibm.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-02-01qdev: drop extra references at creation timePaolo Bonzini1-0/+1
qdev_free and qbus_free have to do unparent+unref, because nobody else drops the initial reference (the one included by object_initialize) before them. For device_init_func and do_device_add, this is trivially correct, since the DeviceState goes out of scope. For qdev_create, qdev_try_create and qbus_init, it is a bit more tricky. What we are doing here is just assuming that the caller knows what it's doing, and won't call qdev_free/qbus_free while the device is still there. This is a pretty reasonable assumption and (behind the scenes) is also what GObject/GTK does. GTK actually has a "floating reference" that goes away as soon as the caller does gtk_container_add or something like that, but in the end qbus_init and qdev_try_create are already adding the new object to its qdev parent! So in the end the two solutions are the same. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-01-26fw_cfg: Splash image loader can overrun a stack variable, fixMarkus Armbruster1-1/+1
read_splashfile() passes the address of an int variable as size_t * parameter to g_file_get_contents(), with a cast to gag the compiler. No problem on machines where sizeof(size_t) == sizeof(int). Happens to work on my x86_64 box (64 bit little endian): the least significant 32 bits of the file size end up in the right place (caller's variable file_size), and the most significant 32 bits clobber a place that gets assigned to before its next use (caller's variable file_type). I'd expect it to break on a 64 bit big-endian box. Fix up the variable types and drop the problematic cast.

2013-01-19vl: Use size_t for sizes in get_boot_devices_list()Markus Armbruster1-3/+3
Code mixes uint32_t, int and size_t. Very unlikely to go wrong in practice, but clean it up anyway. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
