2009-10-06Revert "Fix exit on 'pci_add' Monitor command"Anthony Liguori3-16/+0
This reverts commit 0148fde54c2478ea8a47c8dbfe4c0fb8bda4d996. As requested by Luiz. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06offer right-ctrl as a grab optionDustin Kirkland4-7/+26
Add support for -ctrl-grab to use the right-ctrl button to grab/release the mouse in SDL. The multi-button ctrl-alt and ctrl-alt-shift grab buttons present an accessibility problem to users who cannot press more than one button at a time. https://bugs.edge.launchpad.net/ubuntu/+source/qemu-kvm/+bug/237635 Signed-off-by: Dustin Kirkland <kirkland@canonical.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06add host_device format description to qemu-img manpageAdrian Bridgett1-0/+6
Converting files using "qemu-img convert" onto logical volumes (or any block device) you need to use the currently undocumented "host_device" format. This patch adds the required documentation to the manpage.

2009-10-06Reorganize option rom (+linux kernel) loading.Gerd Hoffmann6-248/+318
This patch adds infrastructure to maintain memory regions which must be restored on reset. That includes roms (vga bios and option roms on pc), but is also used when loading linux kernels directly. Features: - loading files is supported. - passing blobs is supported. - target address range is supported (for optionrom area). - fixed target memory address is supported (linux kernel). New in v2: - writes to ROM are done only at initial boot. - also handle aout and uimage loaders. - drop unused fread_targphys() function. The final memory layout is created once all memory regions are registered. The option roms get addresses assigned and the registered regions are checked against overlaps. Finally all data is copyed to the guest memory. Advantages: (1) Filling memory on initial boot and on reset takes the same code path, making reset more robust. (2) The need to keep track of the option rom load address is gone. (3) Due to (2) option roms can be loaded outside pc_init(). This allows to move the pxe rom loading into the nic drivers for example. Additional bonus: There is a 'info roms' monitor command now. The patch also switches over pc.c and removes the option_rom_setup_reset() and load_option_rom() functions.

This reduce the impact on hosts that have addressing modes with limited offsets. Suggested by Laurent Desnogues. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-10-05block/raw: Add create_options for host_deviceKevin Wolf1-6/+10
Today host_devices have a create function, so they also need a create_options field to prevent qemu-img from complaining. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-05Improve error reporting on file accessJustin M. Forbes2-16/+16
By making the error reporting include strerror(errno), it gives the user a bit more indication as to why qemu failed. This is particularly important for people running qemu as a non root user. Signed-off-by: Justin M. Forbes <jforbes@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-05Win32: Fix vnc support.Stefan Weil1-2/+21

2009-10-05Rename pci_create_noinit() to pci_create()Markus Armbruster5-9/+9
It's qdev_create() specialized for PCI, so name it accordingly. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-05Fix pci_add nic not to exit on bad modelMarkus Armbruster15-32/+71
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to create the NIC. When MODEL is unknown or "?", this prints to stderr and terminates the program. Change pci_nic_init() not to treat "?" specially, and to return NULL on failure. Switch uses during startup to new convenience wrapper pci_nic_init_nofail(), which behaves just like pci_nic_init() used to do. Bonus bug fix: we now check for qdev_init() failing there.

2009-10-05Make it obvious that pci_nic_init() can't failMarkus Armbruster3-21/+14
Before this patch, pci_nic_init() returns NULL when it can't find the model in pci_nic_models[]. Except this can't happen, because qemu_check_nic_model_list() just searched for model in pci_nic_models[], and terminated the program on failure. Repeating the search here is pointless. Instead, change qemu_check_nic_model_list() to return the model's array index. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-05Fix pci_add storage not to exit on bad first argumentMarkus Armbruster3-3/+12
Monitor command "pci_add ADDR storage ..." does its work in qemu_pci_hot_add_nic(). It called pci_create(..., ADDR) to create the device. That's wrong, because pci_create() terminates the program when ADDR is invalid. Use pci_get_bus_devfn() and pci_create_noinit() instead.

2009-10-05Fix pci_vga_init() not to ignore bus argumentMarkus Armbruster1-1/+1
Commit a414c306 converted all VGA devices to qdev. It used pci_create_simple() for all devices, except for this one it used pci_create(). That's wrong, because it uses PCI bus#0 regardless of the bus argument. Fix by switching to pci_create_noinit().

2009-10-05virtio-pci: return error if virtio_console_init failsAmit Shah1-0/+3
Currently only one virtio_console device is supported. Trying to add multiple devices fails and such failure should be reported back to the qdev init functions. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-05vnc: Set invalid buffer pointers to NULLStefan Weil1-2/+8
After qemu_free, the pointers for input and output buffers are no longer valid, so set them to NULL (most other calls of qemu_free in vnc.c use this pattern, too). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-05eepro100: Don't allow guests to fail assertionsKevin Wolf1-11/+35
The idea of using assert() for input validation is rather questionable. Let's remove it from eepro100, so that guests need to find more interesting ways if they want to crash qemu. This patch replaces asserts that are directly dependent on guest-accessible data by other means of error handling.

2009-10-05qcow2: Increase maximum cluster size to 2 MBKevin Wolf4-9/+12
This patch increases the maximum qcow2 cluster size to 2 MB. Starting with 128k clusters, L2 tables span 2 GB or more of virtual disk space, causing 32 bit truncation and wraparound of signed integers. Therefore some variables need to use a larger data type. While being at reviewing data types, change some integers that are used for array indices to unsigned. In some places they were checked against some upper limit but not for negative values. This could avoid potential segfaults with corrupted qcow2 images. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-05qemu/virtio-pci: remove unnecessary checkMichael S. Tsirkin1-2/+1

2009-10-05qemu: clean up target page usage in msixMichael S. Tsirkin4-36/+27
Since cpu_register_phys_memory does not require size to be a multiple of target page size, simply make msix page size 0x1000. Do this in msix, reverting part of 5e520a7d500ec2569d22d80f9ef4272a34cb3c80, as we no longer have to pass target page around. Signed-off-by: Michael S.

2009-10-05qemu/virtio: fix reset with device removalMichael S. Tsirkin1-6/+8
virtio pci registers its own reset handler, but fails to unregister it, which will lead to crashes after device removal.

Everything using standard isa I/O ports and IRQ windup is considerd being an actual isa device.

isa-fdc is completely qdev-ified with this patch applied, all configuration uses properties. sysbus-fdc needs dma_channel config fixed. There is only one user (mips_jazz) which uses dma channel 0.

They can be put in use with drive attributes, like this: drive_add dummy if=none,id=mydisk,file=/some/disk.img device_add virtio-blk-pci,drive=mydisk which is the monitor aequivalent to these command line switches: -drive if=none,id=mydisk,file=/some/disk.img -device virtio-blk-pci,drive=mydisk Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Changes: * drive_uninit() wants a DriveInfo now. * drive_uninit() also calls bdrv_delete(), so callers don't need to do that. * drive_uninit() calls are moved over to the ->exit() callbacks, destroy_bdrvs() is zapped. * setting bdrv->private is not needed any more as the only user (destroy_bdrvs) is gone. * usb-storage needs no drive_uninit, scsi-disk will handle that.

Adds device_add and device_del commands. device_add accepts accepts the same syntax like the -device command line switch. device_del expects a device id. So you should tag your devices with ids if you want to remove them later on, like this: device_add pci-ohci,id=ohci device_del ohci Unplugging via pci_del or usb_del works too.
