2018-06-15block: Remove deprecated -drive option serialKevin Wolf
The -drive option serial was deprecated in QEMU 2.10. It's time to remove it. Tests need to be updated to set the serial number with -global instead of using the -drive option.

2018-06-15block: Remove deprecated -drive geometry optionsKevin Wolf
The -drive options cyls, heads, secs and trans were deprecated in QEMU 2.10. It's time to remove them. hd-geo-test tested both the old version with geometry options in -drive and the new one with -device. Therefore the code using -drive doesn't have to be replaced there, we just need to remove the -drive test cases. This in turn allows some simplification of the code.

2018-06-01sandbox: disable -sandbox if CONFIG_SECCOMP undefinedYi Min Zhao
If CONFIG_SECCOMP is undefined, the option 'elevatedprivileges' remains compiled. This would make libvirt set the corresponding capability and then trigger failure during guest startup. This patch moves the code regarding seccomp command line options to qemu-seccomp.c file and wraps qemu_opts_foreach finding sandbox option with CONFIG_SECCOMP. Because parse_sandbox() is moved into qemu-seccomp.c file, change seccomp_start() to static function.

2018-05-31xen/hvm: correct reporting of modified memory under physmap during migrationIgor Druzhinin
When global_log_dirty is enabled VRAM modification tracking never worked correctly. The address that is passed to xen_hvm_modified_memory() is not the effective PFN but RAM block address which is not the same for VRAM. We need to make a translation for this address into PFN using physmap. Since there is no way to access physmap properly inside xen_hvm_modified_memory() let's make it a global structure.

2018-05-30cli: add --preconfig optionIgor Mammedov
This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state, allowing the configuration of QEMU from QMP before the machine jumps into board initialization code of machine_run_board_init() The intent is to allow management to query machine state and additionally configure it using previous query results within one QEMU instance (i.e. eliminate the need to start QEMU twice, 1st to query board specific parameters and 2nd for actual VM start using query results for additional parameters). The new option complements -S option and could be used with or without it. The difference is that -S pauses QEMU when the machine is completely initialized with all devices wired up and ready to execute guest code (QEMU needs only to unpause VCPUs to let guest execute its code), while the "preconfig" option pauses QEMU early before board specific init callback (machine_run_board_init) is executed and allows the configuration of machine parameters which will be used by board init code. When early introspection/configuration is done, command 'exit-preconfig' should be used to exit RUN_STATE_PRECONFIG and transition to the next requested state (i.e. if -S is used then QEMU will pause the second time when board/device initialization is completed or start guest execution if -S isn't provided on CLI) PS: Initially 'preconfig' is planned to be used for configuring numa topology depending on board specified possible cpus layout.

2018-03-08vl: introduce vm_shutdown()Stefan Hajnoczi
Commit 00d09fdbbae5f7864ce754913efc84c12fdf9f1a ("vl: pause vcpus before stopping iothreads") and commit dce8921b2baaf95974af8176406881872067adfa ("iothread: Stop threads before main() quits") tried to work around the fact that emulation was still active during termination by stopping iothreads. They suffer from race conditions: 1. virtio_scsi_handle_cmd_vq() racing with iothread_stop_all() hits the virtio_scsi_ctx_check() assertion failure because the BDS AioContext has been modified by iothread_stop_all(). 2. Guest vq kick racing with main loop termination leaves a readable ioeventfd that is handled by the next aio_poll() when external clients are enabled again, resulting in unwanted emulation activity. This patch obsoletes those commits by fully disabling emulation activity when vcpus are stopped. Use the new vm_shutdown() function instead of pause_all_vcpus() so that vm change state handlers are invoked too. Virtio devices will now stop their ioeventfds, preventing further emulation activity after vm_stop(). Note that vm_stop(RUN_STATE_SHUTDOWN) cannot be used because it emits a QMP STOP event that may affect existing clients. It is no longer necessary to call replay_disable_events() directly since vm_shutdown() does so already. Drop iothread_stop_all() since it is no longer used.

2018-03-05net: Add a new convenience option "--nic" to configure default/on-board NICsThomas Huth
The legacy "-net" option can be quite confusing for the users since most people do not expect to get a "vlan" hub between their emulated guest hardware and the host backend. But so far, we are also not able to get rid of "-net" completely, since it is the only way to configure on-board NICs that can not be instantiated via "-device" yet. It's also a little bit shorter to type "-net nic -net tap" instead of "-device xyz,netdev=n1 -netdev tap,id=n1". So what we need is a new convenience option that is shorter to type than the full -device + -netdev stuff, and which can be used to configure the on-board NICs that can not be handled via -device yet. Thus this patch now provides such a new option "--nic": It adds an entry in the nd_table to configure a on-board / default NIC, creates a host backend and connects the two directly, without a confusing "vlan" hub inbetween.

2018-02-13hax: Support guest RAM sizes of 4GB or moreYu Ning
Since HAX_VM_IOCTL_ALLOC_RAM takes a 32-bit size, it cannot handle RAM blocks of 4GB or larger, which is why HAXM can only run guests with less than 4GB of RAM. Solve this problem by utilizing the new HAXM API, HAX_VM_IOCTL_ADD_RAMBLOCK, which takes a 64-bit size, to register RAM blocks with the HAXM kernel module. The new API is first added in HAXM 7.0.0, and its availablility and be confirmed by the presence of the HAX_CAP_64BIT_RAMBLOCK capability flag. When the guest RAM size reaches 7GB, QEMU will ask HAXM to set up a memory mapping that covers a 4GB region, which will fail, because HAX_VM_IOCTL_SET_RAM also takes a 32-bit size. Work around this limitation by splitting the large mapping into small ones and calling HAX_VM_IOCTL_SET_RAM multiple times.

2018-01-29tpm: add CRB deviceMarc-André Lureau
tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB) Interface as defined in TCG PC Client Platform TPM Profile (PTP) Specification Family “2.0” Level 00 Revision 01.03 v22. The PTP allows device implementation to switch between TIS and CRB model at run time, but given that CRB is a simpler device to implement, I chose to implement it as a different device. The device doesn't implement other locality than 0 for now (my laptop TPM doesn't either, so I assume this isn't so bad) Tested with some success with Linux upstream and Windows 10, seabios & modified ovmf. The device is recognized and correctly transmit command/response with passthrough & emu. However, we are missing PPI ACPI part atm.

2018-01-29tpm: replace GThreadPool with AIO threadpoolMarc-André Lureau
The TPM backend uses a GThreadPool to handle IO in a seperate thread. However, GThreadPool isn't integrated with Qemu main loops, making it unnecessarily complicated to deal with. Qemu has a AIO threadpool, that is better integrated with loops and various IO functions, provides completion BH by default etc. Remove the only user of GThreadPool from qemu, use AIO threadpool. Note that the backend: - no longer accepts queing multiple requests (unneeded so far) - increase ref to itself when handling a command, for extra safety - tpm_backend_thread_end() is renamed tpm_backend_finish_sync() and will wait for completion of BH (request_completed), which will help migration handling.

2018-01-25sdl: reorganize -no-frame supportGerd Hoffmann
Drop no_frame flag from sdl_display_init argument list, use a global variable instead. This is temporary until -no-frame support is dropped altogether when we remove sdl1 support. Remove any traces of noframe from sdl2 code. It is just dead code as sdl2 doesn't support the SDL_NOFRAME window flag any more.
