This patch switches pc s3 suspend over to the new infrastructure.
The cmos_s3 qemu_irq is killed, the new notifier is used instead.
The xen hack goes away with that too, the hypercall can simply be
done in a notifier function now.
This patch also makes the guest actually stay suspended instead
of leaving suspend instantly, so it is useful for more than just
testing whenever the suspend/resume cycle actually works.

The commit's purpose is laudable:
The only way for chardev drivers to communicate an error was to
return a NULL pointer, which resulted in an error message that
said _that_ something went wrong, but not _why_.
It attempts to achieve it by changing the interface to return 0/-errno
and update qemu_chr_open_opts() to use strerror() to display a more
helpful error message. Unfortunately, it has serious flaws:
1. Backends "socket" and "udp" return bogus error codes, because
qemu_chr_open_socket() and qemu_chr_open_udp() assume that
unix_listen_opts(), unix_connect_opts(), inet_listen_opts(),
inet_connect_opts() and inet_dgram_opts() fail with errno set
appropriately. That assumption is wrong, and the commit turns
unspecific error messages into misleading error messages. For
instance:
$ qemu-system-x86_64 -nodefaults -vnc :0 -chardev socket,id=bar,host=xxx
inet_connect: host and/or port not specified
chardev: opening backend "socket" failed: No such file or directory
ENOENT is what happens to be in my errno when the backend returns
-errno. Let's put ERANGE there just for giggles:
$ qemu-system-x86_64 -nodefaults -vnc :0 -chardev socket,id=bar,host=xxx -drive if=none,iops=99999999999999999999
inet_connect: host and/or port not specified
chardev: opening backend "socket" failed: Numerical result out of range
Worse: when errno happens to be zero, return -errno erroneously
signals success, and qemu_chr_new_from_opts() dies dereferencing
uninitialized chr. I observe this with "-serial unix:".
2. All qemu_chr_open_opts() knows about the error is an errno error
code. That's simply not enough for a decent message. For instance,
when inet_dgram() can't resolve the parameter host, which errno code
should it use? What if it can't resolve parameter localaddr?
Clue: many backends already report errors in their open methods.
Let's revert the flawed commit along with its dependencies, and fix up
the silent error paths instead.

The conditions for detecting no free target or LUN were wrong.
The LUN loop was followed by an "if" condition that is never
true, because the loop is exited as soon as lun becomes equal
to bus->info->max_lun, and never becomes greater than it.
The target loop had a wrong condition (<= instead of <). Once
this is fixed, the loop would fail in the same way as the LUN
loop.
The fix is to see whether scsi_device_find returned the device with the
last (channel, target, LUN) pair, and fail if so.

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)

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

This enables acceleration for MMIO-based TPR registers accesses of
32-bit Windows guest systems. It is mostly useful with KVM enabled,
either on older Intel CPUs (without flexpriority feature, can also be
manually disabled for testing) or any current AMD processor.
The approach introduced here is derived from the original version of
qemu-kvm. It was refactored, documented, and extended by support for
user space APIC emulation, both with and without KVM acceleration. The
VMState format was kept compatible, so was the ABI to the option ROM
that implements the guest-side para-virtualized driver service. This
enables seamless migration from qemu-kvm to upstream or, one day,
between KVM and TCG mode.
The basic concept goes like this:
- VAPIC PV interface consisting of I/O port 0x7e and (for KVM in-kernel
irqchip) a vmcall hypercall is registered
- VAPIC option ROM is loaded into guest
- option ROM activates TPR MMIO access reporting via port 0x7e
- TPR accesses are trapped and patched in the guest to call into option
ROM instead, VAPIC support is enabled
- option ROM TPR helpers track state in memory and invoke hypercall to
poll for pending IRQs if required

This will allow the APIC core to file a TPR access report. Depending on
the accelerator and kernel irqchip mode, it will either be delivered
right away or queued for later reporting.
In TCG mode, we can restart the triggering instruction and can therefore
forward the event directly. KVM does not allows us to restart, so we
postpone the delivery of events recording in the user space APIC until
the current instruction is completed.
Note that KVM without in-kernel irqchip will report the address after
the instruction that triggered the access.

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.

Add a field to XHCITransfer to correctly keep track of NAK'ed usb
packets. Retry transfers when the endpoint is kicked again. Implement
wakeup_endpoint bus op so we can kick the endpoint when needed.
With this patch applied the emulated hid devices are working correctly
when hooked up to xhci. usb-tabled without polling, yay!

Add usb bus op which is called whenever a usb endpoint becomes ready,
so the host adapter emulation can react on that event.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
Devices must specify which endpoint has data to transfer now.
The plan is to use the usb_wakeup() not only for remove wakeup support,
but for "data ready" signaling in general, so we can move away from
constant polling to event driven usb device emulation.

With the separation of the device lookup (via usb_find_device) and
packet processing we can lookup device and endpoint before setting up
the usb packet. So we can initialize USBPacket->ep early and keep it
valid for the whole lifecycle of the USBPacket. Also the devaddr and
devep fields are not needed any more.

There is no reason to have a separate usb_generic_handle_packet function
any more, fold it into usb_handle_packet(). Also call the do_token_*
functions which handle control transfer emulation for control pipe
packets only.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
All drivers except usb-hub use usb_generic_handle_packet. The only
reason the usb hub has its own function is that it used to be called
with packets which are intended for downstream devices. With the new,
separate device lookup step this doesn't happen any more, so the need
for a different handle_packet callback is gone.
So we can kill the handle_packet callback and just call
usb_generic_handle_packet directly. The special hub handling in
usb_handle_packet() can go away for the same reason.

Implement the find_device callback for the usb hub. It'll loop over all
ports, calling usb_find_device for all enabled ports until it finds a
matching device.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
Add usb_find_device(). This function will check whenever a device with
a specific address is connected to the specified port. Usually this
will just check state and address of the device hooked up to the port,
but in case of a hub it will ask the hub to check all hub ports for a
matching device.
This patch doesn't put the code into use yet, see the following patches
for details.
The master plan is to separate device lookup and packet processing.
Right now the usb code simply walks all devices, calls
usb_handle_packet() on each until one accepts the packet (by returning
something different that USB_RET_NODEV). I want to have a device lookup
first, then call usb_handle_packet() once, for the device which actually
processes the packet.

The USB subsystem pipes internal reset notifications through
usb_handle_packet() with a special magic PID. This indirection
is a pretty pointless excercise as it ends up being handled by
usb_generic_handle_packet anyway.
Replace the USB_MSG_RESET with a usb_device_reset() function
which can be called directly. Also rename the existing usb_reset()
function to usb_port_reset() to avoid confusion.

According to the EHCI spec port ownership should revert to the EHCI controller

The OS is allowed to make the UHCI Controller run in circles. That is
usually done to serve multiple connected USB devices in a robin-round
fashion, so the available USB bandwidth is evenly distributed between
devices.
The uhci emulation handles this in a very poor way though. When it
figures it runs in circles it stops processing unconditionally, so
it usually processes at most a single transfer desriptor per queue,
even if there are multiple transfer descriptors are queued up.
This patch makes uhci act in a more sophisticated way. It keeps track
of successful processed transfer descriptors and transfered bytes. Then
it will stop processing when there is nothing to do (no transfer
descriptor was completed the last round) or when the transfered data
reaches the usb bandwidth limit.
Result is that the usb-storage devices connected to uhci are ten times
faster, mkfs.vfat time for a 64M stick goes down from five seconds to
a half second. Reason for this is that we are now processing up to 20
transfer descriptors (with 64 bytes each) per frame instead of a single
one.

bdrv_aio_cancel() can trigger bdrv_aio_flush() which makes all aio
that is currently in flight finish. So what we do is:
port reset
detect ncq in flight
cancel ncq
delete ncq sg list
at which point we have double freed the sg list. Instead, with this
patch we do:
port reset
detect ncq in flight
cancel ncq
check if we are really still in flight
delete ncq sg list
which makes things work and gets rid of the race.
