2009-11-21tap-bsd: handle ifname on FreeBSD hostsJuergen Lock
Handle ifname on FreeBSD hosts; if no ifname is given, always start the search from tap0. (Simplified/cleaned up version of what has been in the FreeBSD ports for a long time.) Signed-off-by: Juergen Lock <nox@jelal.kn-bremen.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-11-21Fix tap breakage on BSD hosts (no IFF_VNET_HDR)Juergen Lock
net/tap-bsd.c was assuming IFF_VNET_HDR was always available, which I think isn't true on any BSD. Signed-off-by: Juergen Lock <nox@jelal.kn-bremen.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-11-21Fix OpenBSD build of qemu-ioBlue Swirl
GCC 3.3.5 generates warnings for static forward declarations of data, so rearrange code to use static forward declarations of functions instead. Use <getopt.h> for optind instead of local definition. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

Since c32d766af127f68bb75ba5689f2f5239227bf559, qemu-io should be portable. It is currently built only on linux and mingw32. This patch enables qemu-io on all platforms. Tested on FreeBSD. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-11-17Add linuxboot to BLOBSAlexander Graf
We should install linuxboot.bin too, so let's add it to the to-be-installed blobs. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Convert linux bootrom to external rom and fw_cfgAlexander Graf
We already have a working multiboot implementation that uses fw_cfg to get its kernel module etc. data in int19 runtime now. So what's missing is a working linux boot option rom. While at it I figured it would be a good idea to take the opcode generator out of pc.c and instead use a proper option rom, like we do with multiboot. So here it is - an fw_cfg using option rom for -kernel with linux! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Move common option rom code to header fileAlexander Graf
We will have a linux boot option rom soon, so let's take all functionality that might be useful for both to a header file that both roms can include. That way we only have to write fw_cfg access code once. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Convert multiboot to fw_cfg backed data storageAlexander Graf
Right now we load the guest kernel to RAM, fire off the BIOS, hope it doesn't clobber memory and run an option rom that jumps into the kernel. That breaks with SeaBIOS, as that clears memory. So let's read all kernel, module etc. data using the fw_cfg interface when in the int19 handler. This patch implements said mechanism for multiboot.

2009-11-17Introduce rom_copyAlexander Graf
We have several rom helpers currently, but none of them can get us code that spans several roms into a pointer. This patch introduces a function that copies over rom contents. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-17Add test suite for json marshallingAnthony Liguori
By reusing the qjson test suite. After checking that we can demarshal, marshal again and compared to the expected decoded value. This doesn't work so well for floats because they cannot be accurately represented in decimal but we try our best. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Provide marshalling mechanism for jsonAnthony Liguori
This introduces qobject_to_json which will convert a QObject to a JSON string representation. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17QDict: Introduce qdict_iter()Luiz Capitulino

2009-11-17Add a QObject JSON wrapperAnthony Liguori
This provides a QObject interface for creating QObjects from a JSON expression. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Add a JSON parserAnthony Liguori
This is the third and final stage of the JSON parser. It parses lexical tokens performing grammar validation and creating the final QObject representation. It uses a recursive decent parser. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Add a JSON message boundary identifierAnthony Liguori
The second stage of our JSON parser is a simple state machine that identifies individual JSON values by counting the levels of nesting of tokens. It does not perform grammar validation. We use this to emit a full JSON value to the parser. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Add a lexer for JSONAnthony Liguori
Our JSON parser is a three stage parser. The first stage tokenizes the stream into a set of lexical tokens. Since the lexical grammar is regular, we can use a finite state machine to model it. The state machine will emit tokens as they are identified. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-17Add operations to qlist to allow it to be used as a stackAnthony Liguori
This makes lists no longer invariant. It's a very useful bit of functionality though. To deal with the fact that lists are no longer invariant, introduce a deep copy mechanism for lists. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

QDECREF does not properly escape the macro arguments which can lead to unexpected syntax errors. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-17kvm: x86: Refactor use of interrupt_bitmapJan Kiszka
Drop interrupt_bitmap from the cpustate and solely rely on the integer interupt_injected.

2009-11-17Enable migration without shared storage from the monitorlirans@il.ibm.com
This patch adds the option to activate non-shared storage migration from the monitor. The migration command is as follows: (qemu) migrate -d tcp:0:4444 # for ordinary live migration (qemu) migrate -d -b tcp:0:4444 # for live migration with complete storage copy (qemu) migrate -d -i tcp:0:4444 # for live migration with incremental storage copy, storage is cow based. Changes from v4: - Minor coding style issues. Signed-off-by: Liran Schour <lirans@il.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Block live migrationlirans@il.ibm.com
This patch introduces block migration called during live migration. Block are being copied to the destination in an async way. First the code will transfer the whole disk and then transfer all dirty blocks accumulted during the migration. Still need to improve transition from the iterative phase of migration to the end phase. For now transition will take place when all blocks transfered once, all the dirty blocks will be transfered during the end phase (guest is suspended). Changes from v4: - Global variabels moved to a global state structure allocated dynamically. - Minor coding style issues. - Poll block.c for tracking of dirty blocks instead of manage it here. Signed-off-by: Liran Schour <lirans@il.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Expose a mechanism to trace block writeslirans@il.ibm.com
To support live migration without shared storage we need to be able to trace writes to disk while migrating. This Patch expose dirty block tracking per device to be polled from upper layer. Changes from v4: - Register dirty tracking for each block device. - Minor coding style issues. - Block.c will now manage a dirty bitmap per device once bdrv_set_dirty_tracking() is called. Bitmap is polled by the upper layer (block-migration.c). Signed-off-by: Liran Schour <lirans@il.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17char: rename qemu_chr_reset to qemu_chr_generic_openAmit Shah
This function sends out the OPENED event to backends that have drive the chardevs. The 'reset' is now a historical artifact and we can now just call the function for what it is. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17char: Remove special init_reset handlingAmit Shah
The initial_reset sent to chardevs doesn't do much other than setting a bool to true. Char devices are interested in the open event and that gets sent whenever the device is opened. Moreover, the reset logic breaks as and when qemu's bh scheduling changes. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17char: don't limit data sent to backends to 1k per bufferAmit Shah
chardevs have a 'can_read' function via which backends specify the amount of data they can receive. When can_read returns > 0, apps can start sending data. However, each chardev driver here allows a max. of 1k bytes inspite of the backend being able to receive more. The best we can do here is to allocate s->max_size bytes from the heap on each call (which is the number returned by the backend from the can_read call). This is an intermediate step to bump up the bytes written in each call to 4k. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
