2009-07-27kill drives_tableGerd Hoffmann36-343/+308
First step cleaning up the drives handling. This one does nothing but removing drives_table[], still it became seriously big. drive_get_index() is gone and is replaced by drives_get() which hands out DriveInfo pointers instead of a table index. This needs adaption in *tons* of places all over. The drives are now maintained as linked list. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-27qdev/pci: hook up i440fx.Gerd Hoffmann2-26/+85
Hook i44fx pcihost into sysbus. Convert Host bridge and ISA bridge pci devices to qdev. Tag as no-user. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-27qdev: add -device command line option.Gerd Hoffmann2-33/+66
The -device switch is the users frontend to the qdev_device_add function added by the previous patch. Also adds a linked list where command line options can be saved. Use it for the new -device and for the -usbdevice and -bt switches. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-27qdev: bus walker + qdev_device_add()Gerd Hoffmann2-0/+252
This patch implements a parser and qdev tree walker for bus paths and adds qdev_device_add on top of this. A bus path can be: (1) full path, i.e. /i440FX-pcihost/pci.0/lsi/scsi.0 (2) bus name, i.e. "scsi.0". Best used together with id= to make sure this is unique. (3) relative path starting with a bus name, i.e. "pci.0/lsi/scsi.0" For the (common) case of a single child bus being attached to a device it is enougth to specify the device only, i.e. "pci.0/lsi" will be accepted too. qdev_device_add() adds devices and accepts bus= parameters to find the bus the device should be attached to. Without bus= being specified it takes the first bus it finds where the device can be attached to (i.e. first pci bus for pci devices, ...).

2009-07-27qdev: create default bus names.Gerd Hoffmann2-1/+25
Create a default bus name if none is passed to qbus_create(). If the parent device has DeviceState->id set it will be used to create the bus name,. i.e. -device lsi,id=foo will give you a scsi bus named "foo.0". If there is no id BusInfo->name (lowercased) will be used instead, i.e. -device lsi will give you a scsi bus named "scsi.0". A scsi adapter with two scsi busses would have "scsi.0" and "scsi.1" or "$id.0" and "$id.1" busses. The numbers of the child busses are per device, i.e. when adding two lsi adapters both will have a "*.0" child bus.

2009-07-27Add a pc-0.11 machine type and make the pc type an aliasMark McLoughlin1-1/+2
The pc-0.11 type allows users of qemu-0.11 to use a machine type which they know will remain compatible when the upgrade to qemu-0.12. Management tools may choose to canonicalize the 'pc' machine type to 'pc-0.11' so that if the 'pc' alias changes target in future versions of qemu, the machine type used will remain compatible.

2009-07-27Add machine type aliasesMark McLoughlin2-0/+6
Add an 'alias' field to QEMUMachine and display it in the output of 'qemu -M ?' with an '(aliased to foo)' suffix. Aliases can change targets in newer versions of qemu, so management tools may choose canonicalize machine types to ensure that if a user chooses an alias, that the actual machine type used will remain compatible in future. This is intended to mimic a symlink to a machine description file. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-27Add support for fd=name to tap and socket networkingMark McLoughlin1-7/+35
This allows a program to initialize a host networking device using a file descriptor passed over a unix monitor socket. The program must first pass the file descriptor using SCM_RIGHTS ancillary data with the getfd monitor command. It then may do "host_net_add tap fd=name" to use the named file descriptor.

2009-07-27Add getfd and closefd monitor commandsMark McLoughlin2-0/+87
Add monitor commands to support passing file descriptors via SCM_RIGHTS. getfd assigns the passed file descriptor a name for use with other monitor commands. closefd allows passed file descriptors to be closed. If a monitor command actually uses a named file descriptor, closefd will not be required. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-27Add SCM_RIGHTS support to unix socket character devicesMark McLoughlin2-1/+56
If a file descriptor is passed via a message with SCM_RIGHTS ancillary data on a unix socket, store the file descriptor for use in the chr_read() handler. Close the file descriptor if it was not used. The qemu_chr_get_msgfd() API provides access to the passed descriptor.

2009-07-27Make tcp_chr_read() use recvmsg()Mark McLoughlin1-1/+24

2009-07-27sparc64 really implement itlb/dtlb automatic replacement writesIgor Kovalenko3-90/+84
- implement "used" bit in tlb translation entry - mark tlb entry used if qemu code/data translation succeeds - fold i/d mmu replacement writes code into replace_tlb_1bit_lru which adds 1bit lru replacement algorithm; previously code tried to replace first unlocked entry only - extract more bitmasks to named macros - add "immu" or "dmmu" type name to debugging output where appropriate Signed-off-by: igor.v.kovalenko@gmail.com -- Kind regards, Igor V.

2009-07-27sparc64 name mmu registers and general cleanupIgor Kovalenko4-111/+225
- add names to mmu registers, this helps understanding the code which uses/modifies them. - fold i/d mmu tlb entries tag and tte arrays into arrays of tlb entries - extract demap_tlb routine (code duplication) - extract replace_tlb routine (code duplication) - flush qemu tlb translations when replacing sparc64 mmu tlb entries I have no test case which demands flushing qemu translations, and this patch should have no other visible changes to runtime.

2009-07-26PPC: Round VGA BIOS size to page boundaryAlexander Graf2-0/+8
When giving KVM a slot of a size not on page boundary, it chokes. So let's just round up the VGA BIOS size so nobody complains anymore and we don't need to implement sub-page slots. Required for booting a PPC guest in KVM. Signed-off-by: Alexander Graf <agraf@suse.de>

KVM can have an in-kernel pit or irqchip. While we don't implement it yet, having a way for test for it (that always returns zero) will allow us to reuse code in qemu-kvm that tests for it. Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-22introduce on_vcpuGlauber Costa1-6/+29
on_vcpu is a qemu-kvm function that will make sure that a specific piece of code will run on a requested cpu. We don't need that because we're restricted to -smp 1 right now, but those days are likely to end soon. So for the benefit of having qemu-kvm share more code with us, I'm introducing our own version of on_vcpu(). Right now, we either run a function on the current cpu, or abort the execution, because it would mean something is seriously wrong. As an example code, I "ported" kvm_update_guest_debug to use it, with some slight differences from qemu-kvm. This is probably 0.12 material Signed-off-by: Glauber Costa <glommer@redhat.com> CC: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-22qemu-io: reject invalid patternChristoph Hellwig1-6/+38
Replace the use of atoi which is used for pattern parsing currently with strtol. Atoi won't parse sedecimal pattern values (it always returns 0), but qemu-iotests use such pattern values. Also reject every pattern that is not a unsigned char as we pass the pattern to memset which expect a bye value (despite having the pattern argument declared as int). Based on an earlier patch by Stefan Weil which did not include the error handling.

2009-07-22qemu-io: Rework alloc commandKevin Wolf1-8/+14
The alloc command in qemu-io is mostly useless currently. Instead of doing a single call to bdrv_is_allocated, we must call bdrv_is_allocated in a loop until we have found out for each requested sector if it is allocated or not (bdrv_is_allocated returns a number of sectors that are known to be in the same state as the first one, but it is not required to include all of them) This changes the output format of the alloc command so that a change to the expected output of qemu-iotests 019 is necessary once this is included.

2009-07-22vmdk: Fix backing file handlingKevin Wolf1-14/+15
Instead of storing the backing file in its own BlockDriverState, VMDK uses the BlockDriverState of the raw image file it opened. This is wrong and breaks functions that access the backing file or protocols. This fix replaces all occurrences of s->hd->backing_* with bs->backing_*. This fixes qemu-iotests failure in 020 (Commit changes to backing file). Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-22Fake dirty loggin when it's not thereAlexander Graf1-1/+12
Some KVM platforms don't support dirty logging yet, like IA64 and PPC, so in order to still have screen updates on those, we need to fake it. This patch just tells the getter function for dirty bitmaps, that all pages within a slot are dirty when the slot has dirty logging enabled. That way we can implement dirty logging on those platforms sometime when it drags down performance, but share the rest of the code with dirty logging capable platforms.
