12 years agosrp: Don't use QEMU_PACKED for single elements of a structured type

QEMU_PACKED results in a MinGW compiler warning when it is

warning: 'gcc_struct' attribute ignored

Using QEMU_PACKED for the whole structure avoids the compiler warning

usb-redir: Never return USB_RET_NAK for async handled packets

USB_RET_NAK is not a valid response for async handled packets (and will
trigger an assert as such).

Also drop the warning when receiving a status of cancelled for packets not
cancelled by qemu itself, this can happen when a device gets unredirected
by the usbredir-host while transfers are pending.

RTC: Update the RTC clock only when reading it

Calculate guest RTC based on the time of the last update, instead of
using timers.  The formula is

    (base_rtc + guest_time_now - guest_time_last_update + offset)

Base_rtc is the RTC value when the RTC was last updated.
Guest_time_now is the guest time when the access happens.
Guest_time_last_update was the guest time when the RTC was last updated.
Offset is used when divider reset happens or the set bit is toggled.

The timer is kept in order to signal interrupts, but it only needs to
run when either UF or AF is cleared.  When the bits are both set, the
timer does not run.

UIP is now synthesized when reading register A.  If the timer is not set,
or if there is more than one second before it (as is the case at the
end of this series), the leading edge of UIP is computed and the rising
edge occurs 220us later.  If the update timer occurs within one second,
however, the rising edge of the AF and UF bits should coincide withe
the falling edge of UIP.  We do not know exactly when this will happen
because there could be delays in the servicing of the timer.  Hence, in
this case reading register A only computes for the rising edge of UIP,
and latches the bit until the timer is fired and clears it.

12 years agokvm: i386: Add classic PCI device assignment

kvm: i386: Add classic PCI device assignment

This adds PCI device assignment for i386 targets using the classic KVM
interfaces. This version is 100% identical to what is being maintained
in qemu-kvm for several years and is supported by libvirt as well. It is
expected to remain relevant for another couple of years until kernels
without full-features and performance-wise equivalent VFIO support are
obsolete.

A refactoring to-do that should be done in-tree is to model MSI and
MSI-X support via the generic PCI layer, similar to what VFIO is already
doing for MSI-X. This should improve the correctness and clean up the
code from duplicate logic.

12 years agotcg/s390: fix ld/st with CONFIG_TCG_PASS_AREG0

tcg/s390: fix ld/st with CONFIG_TCG_PASS_AREG0

The load/store slow path has been broken in e141ab52d:
- We need to move 4 registers for store functions and 3 registers for
  load functions and not the reverse.
- According to the s390x calling convention the arguments of a function
  should be zero extended. This means that the register shift should be
  done with TCG_TYPE_I64 to ensure the higher word is correctly zero
  extended when needed.

I am aware that CONFIG_TCG_PASS_AREG0 is being removed and thus that
this patch can be improved, but doing so means it can also be applied to
the 1.1 and 1.2 stable branches.
