2015-07-09cpu: Change cpu_exec_init() arg to cpu, not envPeter Crosthwaite
The callers (most of them in target-foo/cpu.c) to this function all have the cpu pointer handy. Just pass it to avoid an ENV_GET_CPU() from core code (in exec.c).

2015-07-09translate-all: Change tb_flush() env argument to cpuPeter Crosthwaite
All of the core-code usages of this API have the cpu pointer handy so pass it in. There are only 3 architecture specific usages (2 of which are commented out) which can just use ENV_GET_CPU() locally to get the cpu pointer. The reduces core code usage of the CPU env, which brings us closer to common-obj'ing these core files.

2015-07-09target-ppc: Move cpu_exec_init() call to realize functionBharata B Rao
Move cpu_exec_init() call from instance_init to realize. This allows any failures from cpu_exec_init() to be handled appropriately. Also add corresponding cpu_exec_exit() call from unrealize. cpu_dt_id assignment from instance_init is no longer needed since correct assignment for cpu_dt_id is already present in realizefn.

2015-07-09cpu: Convert cpu_index into a bitmapBharata B Rao
Currently CPUState::cpu_index is monotonically increasing and a newly created CPU always gets the next higher index. The next available index is calculated by counting the existing number of CPUs. This is fine as long as we only add CPUs, but there are architectures which are starting to support CPU removal, too. For an architecture like PowerPC which derives its CPU identifier (device tree ID) from cpu_index, the existing logic of generating cpu_index values causes problems. With the currently proposed method of handling vCPU removal by parking the vCPU fd in QEMU (Ref: http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg02604.html), generating cpu_index this way will not work for PowerPC. This patch changes the way cpu_index is handed out by maintaining a bit map of the CPUs that tracks both addition and removal of CPUs. The CPU bitmap allocation logic is part of cpu_exec_init(), which is called by instance_init routines of various CPU targets. Newly added cpu_exec_exit() API handles the deallocation part and this routine is called from generic CPU instance_finalize. Note: This new CPU enumeration is for !CONFIG_USER_ONLY only. CONFIG_USER_ONLY continues to have the old enumeration logic.

Add an Error argument to cpu_exec_init() to let users collect the error. This is in preparation to change the CPU enumeration logic in cpu_exec_init(). With the new enumeration logic, cpu_exec_init() can fail if cpu_index values corresponding to max_cpus have already been handed out. Since all current callers of cpu_exec_init() are from instance_init, use error_abort Error argument to abort in case of an error.

2015-07-08hw/i386/pc: reflect any FDC @ ioport 0x3f0 in the CMOSLaszlo Ersek
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually: -device isa-fdc,driveA=drive-fdc0-0-0 \ -drive file=...,if=none,id=drive-fdc0-0-0,format=raw then the board-default FDC will be skipped, and only the explicitly requested FDC will exist. qtree-wise, this is correct; however such an FDC is currently not registered in the CMOS, because that code is only reached for the board-default FDC. The pc_cmos_init_late() one-shot reset handler -- one-shot because the CMOS is not reprogrammed during warm reset -- should search for any ISA FDC devices, created implicitly (by board code) or explicitly, and set the CMOS accordingly to the ISA FDC(s) with iobase=0x3f0: - if there is no such FDC, report both drives absent, - if there is exactly one such FDC, report its drives in the CMOS, - if there are more than one such FDCs, then pick one (it is not specified which one), and print a warning about the ambiguity.

2015-07-08ich9: implement strap SPKR pin logicPaulo Alcantara
If the signal is sampled high, this indicates that the system is strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system reboot feature). The status of this strap is readable via the NO_REBOOT bit (CC: offset 0x3410:bit 5). The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit may be set or cleared by software if the strap is sampled low but may not override the strap when it indicates "No Reboot". This patch implements the logic where hardware has ability to set SPKR pin through a property named "noreboot" and it's sampled high by default.

2015-07-07qga: added GuestPCIAddress informationMichael Roth
PCIAddress inforfation is obtained via SetupApi, which provides the information about address, bus, etc. We look throught entire device tree in the system and try to find device object for given volume. For this PDO SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration for a given devicei if it is possible. This is the most convinient way for a userspace service. The lookup is performed for every volume available. However, this information is not mandatory for vss-provider. In order to use SetupApi we need to notify linker about it. We do not need to install additional libs, so we do not make separate configuration option to use libsetupapi.su SetupApi gives as the same information as kernel driver with IRP_MN_QUERY_INTERFACE. https://support.microsoft.com/en-us/kb/253232 Signed-off-by: Olga Krishtal <okrishtal@virtuozzo.com> Signed-off-by: Denis V.

2015-07-07qga: added bus type and disk location pathOlga Krishtal
According to Microsoft disk location path can be obtained via IOCTL_SCSI_GET_ADDRESS. Unfortunately this ioctl can not be used for all devices. There are certain bus types which could be obtained with this API. Please, refer to the following link for more details https://technet.microsoft.com/en-us/library/ee851589(v=ws.10).aspx Bus type could be obtained using IOCTL_STORAGE_QUERY_PROPERTY. Enum STORAGE_BUS_TYPE describes all buses supported by OS. Windows defines more bus types than Linux. Thus some values have been added to GuestDiskBusType.

2015-07-07configure: add configure check for ntdddisk.hMichael Roth
This header file provides w32 ioctl definitions for working with disk devices. Older versions of mingw do not expose this in a useable way, so add a configure check and report it via CONFIG_QGA_NTDDSCSI. Subsequent patches will use this macro to stub out functionality that relies on this in cases where it's not available. Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2015-07-07qga: added mountpoint and filesystem type for single volumeOlga Krishtal
We should use GetVolumeXXX api to work with volumes. This will help us to resolve the situation with volumes without drive letter, i.e. when the volume is mounted as a folder. Such volume is called mounted folder. This volume is a regular mounted volume from all other points of view. The information about non mounted volume is reported as System Reserved. This volume is not mounted and thus it is not writable. GuestDiskAddressList API is not used because operations are performed with volumes but no with disks. This means that spanned disk will be counted and handled as a single volume. It is worth mentioning that the information about every disk in the volume can be queried via IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

2015-07-07qga: added empty qmp_quest_get_fsinfo functionality.Olga Krishtal
We need qmp_quest_get_fsinfo togather with vss-provider, which works with volumes. The call to this function is implemented via FindFirst/NextVolumes. Moreover, volumes in Windows OS are filesystem unit, so it will be more effective to work with them rather with devices. Signed-off-by: Olga Krishtal <okrishtal@virtuozzo.com> Signed-off-by: Denis V.

2015-07-07qga: win32 qmp_guest_network_get_interfaces implementationKirk Allan
By default, IPv4 prefixes will be derived by matching the address to those returned by GetAdaptersInfo. IPv6 prefixes can not be matched this way due to the unpredictable order of entries. In Windows Vista/2008 guests and newer, both IPv4 and IPv6 prefixes can be retrieved from OnLinkPrefixLength. Setting --extra-cflags in the build configuration to "-D_WIN32_WINNT=0x600" or greater makes OnLinkPrefixLength available. Setting --extra-cflags is not required and if not set, the default approach to get the prefix will be taken.

2015-07-07qga/qmp_guest_fstrim: Return per path fstrim resultJustin Ossevoort
The current guest-fstrim support only returns an error if some mountpoint was unable to be trimmed, skipping any possible additional mountpoints. The result of the TRIM operation itself is also discarded. This change returns a per mountpoint result of the TRIM operation. If an error occurs on some mountpoints that error is returned and the guest-fstrim continue with any additional mountpoints. The returned values for errors, minimum and trimmed are dependant on the filesystem, storage stacks and kernel version.

2015-07-07qga/commands-posix: Fix bug in guest-fstrimJustin Ossevoort
The FITRIM ioctl updates the fstrim_range structure it receives. This way the caller can determine how many bytes were trimmed. The guest-fstrim logic reuses the same fstrim_range for each filesystem, effectively limiting each filesystem to trim at most as much as the previous was able to trim. If a previous filesystem would have trimmed 0 bytes, than the next filesystem would report an error 'Invalid argument' because a FITRIM request with length 0 is not valid. This change resets the fstrim_range structure for each filesystem.
