2009-08-27New VMstate save/load infrastructureJuan Quintela2-5/+370
This patch introduces VMState infrastructure, to convert the save/load functions of devices to a table approach. This new approach has the following advantages: - it is type-safe - you can't have load/save functions out of sync - will allows us to have new interesting commands, like dump <device>, that shows all its internal state. - Just now, the only added type is arrays, but we can add structures. - Uses old load_state() function for loading old state.

do_loadvm() is now called from the monitor. load_vmstate() is called by do_loadvm() and when -loadvm command line is used. Command line don't have to play games with vmstop()/vmstart() Signed-off-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-08-27qcow2: Metadata preallocationKevin Wolf2-2/+80
This introduces a qemu-img create option for qcow2 which allows the metadata to be preallocated, i.e. clusters are reserved in the refcount table and L1/L2 tables, but no data is written to them. Metadata is quite small, so this happens in almost no time. Especially with qcow2 on virtio this helps to gain a bit of performance during the initial writes. However, as soon as create a snapshot, we're back to the normal slow speed, obviously. So this isn't the real fix, but kind of a cheat while we're still having trouble with qcow2 on virtio. Note that the option is disabled by default and needs to be specified explicitly using qemu-img create -f qcow2 -o preallocation=metadata.

2009-08-27Move isa_connect_irq calls into isa_create_simpleGerd Hoffmann4-7/+10
Now with isa-bus maintaining the isa irqs we can move the isa_connect_irq() calls into isa_create_simple(). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-27Add isa_reserve_irq().Jes Sorensen7-34/+60
Introduce isa_reserve_irq() which marks an irq reserved and returns the appropriate qemu_irq entry from the i8259 table. isa_reserve_irq() is a temporary interface to be used to allocate ISA IRQs for devices which have not yet been converted to qdev, and for special cases which are not suited for qdev conversions, such as the 'ferr'. This patch goes on top of Gerd Hoffmann's which makes isa-bus.c own the ISA irq table. [ added isa-bus.o to some targets to fix build failures -- kraxel ] Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-27isa bus irq changes and fixes.Gerd Hoffmann9-37/+109
Changes: (1) make isa-bus maintain isa irqs, complain when allocating already taken irqs. (2) note that (1) works only for isa devices converted to qdev already (floppy and ps2/kbd/mouse right now), so more work is needed to make this really useful. (3) split floppy init into isa and sysbus versions. (4) add sysbus->isa bridge & fix -M isapc breakage.

2009-08-27hw/eepro100.c: Use extended TBD only where applicableNaphtali Sprei1-3/+3
Bug fix for segfault when run as i82551 HW: Use Extended TBD only when HW supports it (i82558 and up). Added assertions to guard from such buffer overflow Introduce the MAX_TCB_BYTE_COUNT macro Allocate buf big enough as HW needs (MAX_ETH_FRAME_SIZE -> MAX_TCB_BYTE_COUNT) I don't feel 100% OK with the "s->device >= i82558B" condition since it relies on the numeric (hex) value of those defines, which currently is correct, but changes (which I don't forsee now) might break it.

2009-08-27block/vdi.c: Fix several bugsStefan Weil1-4/+9
* The code for option '-static' was wrong, so image creation always created static images. * Static images created with qemu-img did not set header entry blocks_allocated. * The size of the block map must be rounded to the next multiple of SECTOR_SIZE, otherwise the block map is only read partially for block map sizes which are not a multiple of SECTOR_SIZE.

2009-08-27introduce kvm64 CPUAndre Przywara1-0/+26
In addition to the TCG based qemu64 type let's introduce a kvm64 CPU type, which is the least common denominator of all KVM-capable x86-CPUs (based on Intel Pentium 4 Prescott). It can be used as a base type for migration. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-27allow overriding of CPUID level on command lineAndre Przywara1-10/+29
The CPUID level determines how many CPUID leafs are exposed to the guest. Some features (like multi-core) cannot be propagated without the proper level, but guests maybe confused by bogus entries in some leafs. So add level= and xlevel= to the list of -cpu options to allow the user to override the default settings. While at it, merge unnecessary local variables into one and allow hexadecimal arguments.

2009-08-27set CPUID bits to present cores and threads topologyAndre Przywara1-3/+25
Controlled by the enhanced -smp option set the CPUID bits to present the guest the desired topology. This is vendor specific, but (with the exception of the CMP_LEGACY bit) not conflicting, so we set all bits everytime. There is no real multithreading support for AMD CPUs, so report cores instead.

2009-08-27push CPUID level to 4 to allow Intel multicore decodingAndre Przywara1-2/+2
Intel CPUs store the number of cores in CPUID leaf 4. So push the maxleaf value to 4 to allow the guests access to this leaf. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-27extend -smp parsing to include cores= and threads= optionsAndre Przywara2-9/+59
For injecting multi-core and multi-threading CPU topology into guests extend the -smp syntax to accommodate cores and threads specification. Syntax: -smp smp_value[,cores=nr_cores][,threads=nr_threads]\ [,socket=nr_sockets][,maxcpus=max_cpus] smp_value is the legacy value specifying the total number of vCPUs for the guest. If you specify one of cores, threads or sockets this value can be omitted. Missing values will be computed to fulfill: smp_value = nr_cores * nr_threads * nr_sockets where it will favour sockets over cores over threads (to mimic the current behavior, which will only inject multiple sockets.) So -smp 4,threads=2 will inject two sockets with 2 threads each, -smp cores=4 is an abbreviation for -smp 4,cores=4,threads=1,sockets=1. If max_cpus (the number of hotpluggable CPUs) is omitted, it will be set to smp_value. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Level 15 interrupts are broadcast to all CPUs, each CPU can clear the interrupt using the local Clear Pending register. Update intbit_to_level table. Don't try to raise level 0 interrupts. Calculate pending interrupts based on the separate inputs from master register. Setting or resetting the pending level isn't correct because of overlap of levels. Level 14 is always used for CPU timer interrupts, remove the property. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-08-25target-mips: fix conditional moves off fp condition codesNathan Froyd1-5/+5
Conditional moves off fp condition codes were using the result of get_fp_bit to isolate and test the relevant condition code. However, get_fp_bit returns the bit number of the condition code, not a bitmask. (Compare the use of get_fp_bit in gen_compute_branch1, for instance.) Fixed by shifting a bitmask into place using the result of get_fp_bit in the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

2009-08-24Make the e1000 the default network adapter for the pc target.Anthony Liguori2-3/+3
The ne2k is an ancient card that performs pretty terribly under QEMU. In many modern OSes, there is no longer drivers available for the ne2k. Switch the default network adapter to e1000. This card is more widely suppported and performs rather well under QEMU. There may be very old OSes that had a ne2k driver but not an e1000 driver but I think this is likely the exception. I think the average user is better served with an e1000 vs ne2k. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
