* Add new PCI ID for i82559aMike Nawrocki2017-11-131-1/+1
| | | | | | | | | | Adds a new PCI ID for the i82559a (0x8086 0x1030) interface. The "x-use-alt-device-id" property controls whether this new ID is to be used, and is true by default, and set to false in a compat entry.

* tpm: Added support for TPM emulatorAmarnath Valluri2017-10-131-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces a new TPM backend driver that can communicate with swtpm(software TPM emulator) using unix domain socket interface. QEMU talks to the TPM emulator using QEMU's socket-based chardev backend device. Swtpm uses two Unix sockets for communications, one for plain TPM commands and responses, and one for out-of-band control messages. QEMU passes the data socket to be used over the control channel. The swtpm and associated tools can be found here: https://github.com/stefanberger/swtpm The swtpm's control channel protocol specification can be found here: https://github.com/stefanberger/swtpm/wiki/Control-Channel-Specification Usage: # setup TPM state directory mkdir /tmp/mytpm chown -R tss:root /tmp/mytpm /usr/bin/swtpm_setup --tpm-state /tmp/mytpm --createek # Ask qemu to use TPM emulator with given tpm state directory qemu-system-x86_64 \ [...] \ -chardev socket,id=chrtpm,path=/tmp/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis,tpmdev=tpm0 \ [...] Signed-off-by: Amarnath Valluri <amarnath.valluri@intel.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current VNC default keyboard delay is 1ms. With that we're constantly typing faster than the guest receives keyboard events from an XHCI attached USB HID device. The default keyboard delay time in the input layer however is 10ms. I don't know how that number came to be, but empirical tests on some OpenQA driven ARM systems show that 10ms really is a reasonable default number for the delay. This patch moves the VNC delay also to 10ms. That way our default is much safer (good!) and also consistent with the input layer default (also good!).

* | tests: Avoid non-portable 'echo -ARG'Eric Blake2017-07-111-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX says that backslashes in the arguments to 'echo', as well as any use of 'echo -n' and 'echo -e', are non-portable; it recommends people should favor 'printf' instead. This is definitely true where we do not control which shell is running (such as in makefile snippets or in documentation examples). But even for scripts where we require bash (and therefore, where echo does what we want by default), it is still possible to use 'shopt -s xpg_echo' to change bash's behavior of echo. And setting a good example never hurts when we are not sure if a snippet will be copied from a bash-only script to a general shell script (although I don't change the use of non-portable \e for ESC when we know the running shell is bash). Replace 'echo -n "..."' with 'printf %s "..."', and 'echo -e "..."' with 'printf %b "...\n"', with the optimization that the %s/%b argument can be omitted if the string being printed is a strict literal with no '%', '$', or '`' (we could technically also make this optimization when there are $ or `` substitutions but where we can prove their results will not be problematic, but proving that such substitutions are safe makes the patch less trivial compared to just being consistent). In the qemu-iotests check script, fix unusual shell quoting that would result in word-splitting if 'date' outputs a space. In test 051, take an opportunity to shorten the line. In test 068, get rid of a pointless second invocation of bash.

* 9pfs: local: Add support for custom fmode/dmode in 9ps mapped security modesTobias Schramm2017-06-291-4/+16
| | | | | | | | | | | | | | | | In mapped security modes, files are created with very restrictive permissions (600 for files and 700 for directories). This makes file sharing between virtual machines and users on the host rather complicated. Imagine eg. a group of users that need to access data produced by processes on a virtual machine. Giving those users access to the data will be difficult since the group access mode is always 0. This patch makes the default mode for both files and directories configurable. Existing setups that don't know about the new parameters keep using the current secure behavior. Signed-off-by: Tobias Schramm <tobleminer@gmail.com> Signed-off-by: Greg Kurz <groug@kaod.org>

However cpu index is internal concept and QEMU users have to guess /reimplement qemu's logic/ to map it to a concrete cpu socket/core/thread to make sane CPUs placement across numa nodes. This patch allows to map cpu objects to numa nodes using the same properties as used for cpus with -device/device_add (socket-id/core-id/thread-id/node-id). At present valid properties/values to address CPUs could be fetched using hotpluggable-cpus monitor/qmp command, it will require user to start qemu twice when creating domain to fetch possible CPUs for a machine type/-smp layout first and then the second time with numa explicit mapping for actual usage. The first step results could be saved and reused to set/change mapping later as far as machine type/-smp stays the same. Proposed impl. supports exact and wildcard matching to simplify CLI and allow to set mapping for a specific cpu or group of cpu objects specified by matched properties. For example: # exact mapping x86 -numa cpu,node-id=x,socket-id=y,core-id=z,thread-id=n # exact mapping SPAPR -numa cpu,node-id=x,core-id=y # wildcard mapping, all cpu objects that match socket-id=y # are mapped to node-id=x -numa cpu,node-id=x,socket-id=y Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <1494415802-227633-18-git-send-email-imammedo@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is going to add SLIT table support in QEMU, and provides additional option `dist` for command `-numa` to allow user set vNUMA distance by QEMU command.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a simple FRU support for the BMC simulator. FRUs are loaded from a file which name is specified in the object properties, each entry having a fixed size, also specified in the properties. If the file is unknown or not accessible for some reason, a unique entry of 1024 bytes is created as a default. Just enough to start some simulation. These commands complies with the IPMI spec : "34. FRU Inventory Device Commands".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The new command line option -blockdev works like QMP command blockdev-add. The option argument may be given in JSON syntax, exactly as in QMP. Example usage: -blockdev '{"node-name": "foo", "driver": "raw", "file": {"driver": "file", "filename": "foo.img"} }' The JSON argument doesn't exactly blend into the existing option syntax, so the traditional KEY=VALUE,... syntax is also supported, using dotted keys to do the nesting: -blockdev node-name=foo,driver=raw,file.driver=file,file.filename=foo.img This does not yet support lists, but that will be addressed shortly. Note that calling qmp_blockdev_add() (say via qmp_marshal_block_add()) right away would crash. We need to stash the configuration for later instead. This is crudely done, and bypasses QemuOpts, even though storing configuration is what QemuOpts is for. Need to revamp option infrastructure to support QAPI types like BlockdevOptions.
