2017-09-19hostmem-file: Add "discard-data" optionEduardo Habkost
The new option can be used to indicate that the file contents can be destroyed and don't need to be flushed to disk when QEMU exits or when the memory backend object is removed. Internally, it will trigger a madvise(MADV_REMOVE) call when the memory backend is removed.

2017-07-17vnc: Set default kbd delay to 10msAlexander Graf
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!).

2017-07-11tests: Avoid non-portable 'echo -ARG'Eric Blake
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.

2017-06-299pfs: local: Add support for custom fmode/dmode in 9ps mapped security modesTobias Schramm
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>

2017-05-11numa: add '-numa cpu,...' option for property based node mappingIgor Mammedov
legacy cpu to node mapping is using cpu index values to map VCPU to node with help of '-numa node,nodeid=node,cpus=x[-y]' option. 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>

into staging ppc patch queue 2017-04-26 Here's a respind of my first pull request for qemu-2.10, consisting of assorted patches which have accumulated while qemu-2.9 stabilized. Highlights are: * Rework / cleanup of the XICS interrupt controller * Substantial improvement to the 'powernv' machine type - Includes an MMIO XICS version * POWER9 support improvements - POWER9 guests with KVM - Partial support for POWER9 guests with TCG * IOMMU and VFIO improvements * Assorted minor changes There are several IPMI patches here that aren't usually in my area of maintenance, but there isn't a regular maintainer and these patches are for the benefit of the powernv machine type. This pull request supersedes my 2017-04-26 pull request. This new set fixes a bug in one of the aforementioned IPMI patches which caused clang sanitizer failures (and may have crashed on some libc / host versions). # gpg: Signature made Wed 26 Apr 2017 07:58:10 BST # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.10-20170426: (48 commits) MAINTAINERS: Remove myself from e500 target/ppc: Style fixes e500,book3s: mfspr 259: Register mapped/aliased SPRG3 user read target/ppc: Flush TLB on write to PIDR spapr-cpu-core: Release ICPState object during CPU unrealization ppc/pnv: generate an OEM SEL event on shutdown ppc/pnv: add initial IPMI sensors for the BMC simulator ppc/pnv: populate device tree for IPMI BT devices ppc/pnv: populate device tree for serial devices ppc/pnv: populate device tree for RTC devices ppc/pnv: scan ISA bus to populate device tree ppc/pnv: enable only one LPC bus ppc/pnv: Add support for POWER8+ LPC Controller spapr: remove the 'nr_servers' field from the machine target/ppc: Fix size of struct PPCElfPrstatus ipmi: introduce an ipmi_bmc_gen_event() API ipmi: introduce an ipmi_bmc_sdr_find() API ipmi: provide support for FRUs ipmi: use a file to load SDRs ppc: add IPMI support ...

2017-04-26ipmi: provide support for FRUsCédric Le Goater
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".

2017-04-26ipmi: use a file to load SDRsCédric Le Goater
The IPMI BMC simulator populates the sdr/sensor tables with a minimal set of entries (Watchdog). But some qemu platforms might want to use extra entries for their custom needs. This patch modifies slighty the initializing routine to take into account a larger set read from a file. The name of the file to use is defined through a new 'sdr' property of the simulator device.

2017-04-21xen: use libxendevice model to restrict operationsPaul Durrant
This patch adds a command-line option (-xen-domid-restrict) which will use the new libxendevicemodel API to restrict devicemodel [1] operations to the specified domid. (Such operations are not applicable to the xenpv machine type). This patch also adds a tracepoint to allow successful enabling of the restriction to be monitored. [1] I.e. operations issued by libxendevicemodel. Operation issued by other xen libraries (e.g. libxenforeignmemory) are currently still unrestricted but this will be rectified by subsequent patches.

2017-03-07block: Initial implementation of -blockdevMarkus Armbruster
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.

2017-02-21hw/i386: Deprecate -drive if=scsi with PC machine typesMarkus Armbruster
The PC machines (pc-q35-* pc-i440fx-* pc-* isapc xenfv) automatically create lsi53c895a SCSI HBAs and SCSI devices to honor -drive if=scsi. For giggles, try -drive if=scsi,bus=25,media=cdrom --- this makes QEMU create 25 of them. lsi53c895a is thoroughly obsolete (PCI Ultra2 SCSI, ca. 2000), and currently has no maintainer in QEMU. megasas is a better choice, except with old OSes that lack drivers. virtio-scsi is a much better choice when you have a driver, but only (newish) Linux comes with one in the box. There is no good default that works for all guests. Encourage users to pick a non-obsolete SCSI HBA that works for them by deprecating -drive if=scsi.
