2009-08-27New VMstate save/load infrastructureJuan Quintela1-0/+102
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.

2009-08-27Add isa_reserve_irq().Jes Sorensen6-32/+58
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.

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.

2009-08-25Sparc32: improve interrupt handlingBlue Swirl2-32/+47
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>

2009-08-24Make the e1000 the default network adapter for the pc target.Anthony Liguori1-2/+2
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>

2009-08-24Unbreak large mem support by removing kqemuAnthony Liguori1-11/+1
kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-24Route IOAPIC interrupts via ISA busAvi Kivity4-26/+13
Instead of calling the IOAPIC from the PIC, raise IOAPIC irqs via the ISA bus. As a side effect, IOAPIC lines 16-23 are enabled. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-24Route PC irqs to ISA bus instead of i8259 directlyAvi Kivity1-15/+31
A PC has its motherboard IRQ lines connected to both the PIC and IOAPIC. Currently, qemu routes IRQs to the PIC which then calls the IOAPIC, an incestuous arrangement. In order to clean this up, create a new ISA IRQ abstraction, and have devices raise ISA IRQs (which in turn raise the i8259 IRQs as usual).

2009-08-24QEMU set irq0override in fw_cfgJes Sorensen1-0/+2
Hi, After discussing the issue with Avi, Gleb and a couple others on irq, we came to the conclusion that it is preferred to have QEMU request features from the BIOS, rather than notifying the BIOS that it is running on QEMU or KVM. This way memory ranges can change etc. and an older BIOS will continue to work on newer QEMU if it receives the info as a fw_cfg value. This one also matches what qemu-kvm does for irq0override, except I haven't made it configurable. I leave that as an exercise for whoever would be interested in switching off irq0override. Thanks, Jes Set irq0 override in fw_cfg, informing the BIOS that QEMU expects override on irq0. This matches qemu-kvm, and will help sharing a single BIOS binary.

2009-08-24make vga screen_dump use DisplayState properlyStefano Stabellini1-69/+21
Hi all, currently the vga screen_dump code doesn't use the DisplayState interface properly and tries to replace it temporarily while taking the screenshot. A better approach is to register a DisplayChangeListener, call vga_hw_update, and finally write the ppm in the next call from dpy_update. Testing is appreciated.

2009-08-23Use corect depth from DisplaySurface in vmware_vga.cReimar Döffinger1-3/+3
Hello, for what I can tell, there is no way for vmware_vga to work correctly right now. It assumes that the framebuffer bits-per-pixel and the one from the DisplaySurface are identical (it uses directly the VRAM from vga.c), but it always assumes 3 bytes per pixel, which is never possible with the current version of DisplaySurface. Attached patch fixes that by using ds_get_bits_per_pixel.
