2012-02-22pci: set memory type for memory behind the bridgeMichael S. Tsirkin
As we make upper bits in IO and prefetcheable memory registers writeable, we should declare support for 64 bit prefetcheable memory and 32 bit io in the bridge. This changes the default for apb, dec, but I'm guessing they got the defaults wrong by accident. Alternatively, we could let bridges declare lack of 64 bit support and make the upper bits read-only zero. With this applied, we can drop these bits from express code.

2012-02-22pci: add accessors to get/set registers by maskMichael S. Tsirkin
pci_regs.h specifies many registers by mask + shifted register values. There's always some duplication when using such: for example to override device type, we would need: pci_word_test_and_clear_mask(cap + PCI_EXP_FLAGS, PCI_EXP_FLAGS_TYPE); pci_word_test_and_set_mask(cap + PCI_EXP_FLAGS, PCI_EXP_TYPE_ENDPOINT << (ffs(PCI_EXP_FLAGS_TYPE) - 1)); Getting such registers also uses some duplication: word = pci_get_word(cap + PCI_EXP_FLAGS) & PCI_EXP_FLAGS_TYPE; if ((word >> ffs((PCI_EXP_FLAGS_TYPE) - 1)) == PCI_EXP_TYPE_ENDPOINT) Add API to access such registers in one line: pci_set_word_by_mask(cap + PCI_EXP_FLAGS, PCI_EXP_FLAGS_TYPE, PCI_EXP_TYPE_ENDPOINT) and word = pci_get_word_by_mask(cap + PCI_EXP_FLAGS, PCI_EXP_FLAGS_TYPE) if (word == PCI_EXP_TYPE_ENDPOINT) Signed-off-by: Michael S.

2012-02-22pc_piix/pc_sysfw: enable flash by defaultJordan Justen
Now, the pc-sysfw:rom_only property will default to false which enables flash by default. All pc types below pc-1.1 set rom_only to true. This prevents flash from being enabled on these pc machine types. For pc-1.1 rom_only will use the default (false), which will allow flash to be used for pc-1.1.

2012-02-22hw/pc_sysfw: support system flash memory with pflashJordan Justen
Flash can be enabled by calling pc_system_firmware_init with the system_flash_enabled parameter being non-zero. If system_flash_enabled is zero, then the older qemu rom creation method will be used. If flash is enabled and a pflash image is found, then it is used for the system firmware image. If flash is enabled and a pflash image is not initially found, then a read-only pflash device is created using the -bios filename. KVM cannot execute from a pflash region currently. Therefore, when KVM is enabled, the old rom based initialization method is used. Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-02-22qdev: drop unnecessary parse/print methodsPaolo Bonzini
More qdev printers could have been removed in the previous series, and object_property_parse also made several parsers unnecessary. In fact, the new code is even more robust with respect to overflows, so clean them up! Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-02-22qdev: use built-in QOM string parserPaolo Bonzini
object_property_parse lets us drop the legacy setters when their task is done just as well by the string visitors. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-02-22qdev: accept hex properties only if prefixed by 0xPaolo Bonzini
Hex properties are an obstacle to removal of old qdev string parsing, but even here we can lay down the foundations for future simplification. In general, they are rarely used and their printed form is more interesting than the parsing. For example you'd usually set isa-serial.index instead of isa-serial.iobase. And luckily our main client, libvirt only cares about few of these, and always sets them with a 0x prefix. So the series stops accepting bare hexadecimal numbers, preparing for making legacy properties read-only in 1.3 or so. The read side will stay as long as "info qtree" is with us. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-02-22qdev: accept both strings and integers for PCI addressesPaolo Bonzini
Visitors allow a limited form of polymorphism. Exploit it to support setting the non-legacy PCI address property both as a DD.F string and as an 8-bit integer. The 8-bit integer form is just too clumsy, it is unlikely that we will ever drop it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-02-21Add SPICE support to add_client monitor commandDaniel P. Berrange
With the acceptance of some new APIs to libspice-server.so it is possible to add support for SPICE to the 'add_client' monitor command, bringing parity with VNC. Since SPICE can use TLS or plain connections, the command also gains a new 'tls' parameter to specify whether TLS should be attempted on the injected client sockets. This new feature is only enabled if building against a libspice-server >= 0.10.1 * qmp-commands.hx: Add 'tls' parameter & missing doc for 'skipauth' parameter * monitor.c: Wire up SPICE for 'add_client' command * ui/qemu-spice.h, ui/spice-core.c: Add qemu_spice_display_add_client API to wire up from monitor [1] http://cgit.freedesktop.org/spice/spice/commit/server/spice.h?id=d55b68b6b44f2499278fa860fb47ff22f5011faa http://cgit.freedesktop.org/spice/spice/commit/server/spice.h?id=bd07dde530d9504e1cfe7ed5837fc00c26f36716 Changes in v3: - Added 'optional' flag to new parameters documented - Added no-op impl of qemu_spice_display_add_client when SPICE is disabled during build Signed-off-by: Daniel P.

2012-02-21qxl: don't render stuff when the vm is stopped.Gerd Hoffmann
This patch fixes the local qxl renderer to not kick spice-server in case the vm is stopped. First it is largely pointless because we ask spice-server to process all not-yet processed commands when the vm is stopped, so there isn't much do do anyway. Second we avoid triggering an assert in spice-server. The patch makes sure we still honor redraw requests, even if we don't ask spice-server for updates. This is needed to handle displaysurface changes with a stopped vm correctly. With this patch applied it is possible to take screen shots (via screendump monitor command) from a qxl gpu even in case the guest is stopped. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-02-17input: send kbd+mouse events only to running guests.Gerd Hoffmann
Trying to interact with a stopped guest will queue up the events, then send them all at once when the guest continues running, with a high chance to have them cause unwanted actions.

2012-02-17i8259: Do not clear level-triggered lines in IRR on initJan Kiszka
When an input line is handled as level-triggered, it will immediately raise an IRQ on the output of a PIC again that goes through an init reset.

2012-02-17i8254: Factor out pit_get_channel_infoJan Kiszka
Instead of providing 4 individual query functions for mode, gate, output and initial counter state, introduce a service that queries all information at once. This comes with tiny additional costs for pcspk_callback but with a much cleaner interface. Also, it will simplify the implementation of the KVM in-kernel PIT model.

2012-02-17i8254: Rework & fix interaction with HPET in legacy modeJan Kiszka
When the HPET enters legacy mode, the IRQ output of the PIT is suppressed and replaced by the HPET timer 0. But the current code to emulate this was broken in many ways. It reset the PIT state after re-enabling, it worked against a stale static PIT structure, and it did not properly saved/restored the IRQ output mask in the PIT vmstate. This patch solves the PIT IRQ control in a different way. On x86, it both redirects the PIT IRQ to the HPET, just like the RTC. But it also keeps the control line from the HPET to the PIT. This allows to disable the PIT QEMU timer when it is not needed. The PIT's view on the control line state is now saved in the same format that qemu-kvm is already using. Note that, in contrast to the suppressed RTC IRQ line, we do not need to save/restore the PIT line state in the HPET. As we trigger a PIT IRQ update via the control line, the line state is reconstructed on mode switch.

2012-02-17i8254: Pass alternative IRQ output object on initializationJan Kiszka
HPET legacy emulation will require control over the PIT IRQ output. To enable this, add support for an alternative IRQ output object to the PIT factory function. If the isa_irq number is < 0, this object will be used. This also removes the IRQ number property from the PIT class as we now use a generic GPIO output pin that is connected by the factory function.

2012-02-17hpet: Save/restore cached RTC IRQ levelJan Kiszka
In legacy mode, the HPET suppresses the RTC interrupt delivery via IRQ 8 but keeps track of the RTC output level and applies it when legacy mode is turned off again. This value has to be preserved across save/ restore as it cannot be reconstructed otherwise. To document that a raised rtc_irq_level won't survive a vmload without a hpet/rtc_irq_level subsection, add an explicit clearing to the reset handler.

2012-02-17i8254: Do not raise IRQ level on resetJan Kiszka
Avoid changing the IRQ level to high on reset as it may trigger spurious events. Instead, open-code the effects of pit_load_count(0) in the reset handler. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
