647ee98772 usb-serial: Fix timeout closing the device
Linux guests wait ~30 seconds when closing the emulated /dev/ttyUSB0.
During that time, the kernel driver is sending many control URBs
requesting GetModemStat (5).  Real hardware returns a status with
FTDI_THRE (Transmitter Holding Register) and FTDI_TEMT (Transmitter
Empty) set.  QEMU leaves them clear, and it seems Linux is waiting for
FTDI_TEMT to be set to indicate the tx queue is empty before closing.

Set the bits when responding to a GetModemStat query and avoid the
shutdown delay.

30ad5fdd34 usb-serial: Increase receive buffer to 496
A FTDI USB adapter on an xHCI controller can send 512 byte USB packets.
These are 8 * ( 2 bytes header + 62 bytes data).  A 384 byte receive
buffer is insufficient to fill a 512 byte packet, so bump the receive
size to 496 ( 512 - 2 * 8 ).

87db78f743 usb-serial: chunk data to wMaxPacketSize
usb-serial has issues with xHCI controllers where data is lost in the
VM.  Inspecting the URBs in the guest, EHCI starts every 64 byte boundary
(wMaxPacketSize) with a header.  EHCI hands packets into
usb_serial_token_in() with size 64, so these cannot cross the 64 byte
boundary.  The xHCI controller has packets of 512 bytes and the usb-serial
will just write through the 64 byte boundary.  In the guest, this means
data bytes are interpreted as header, so data bytes don't make it out
the serial interface.

Re-work usb_serial_token_in to chunk data into 64 byte units - 2 byte
header and 62 bytes data.  The Linux driver reads wMaxPacketSize to find
the chunk size, so we match that.

Real hardware was observed to pass in 512 byte URBs (496 bytes data +
8 * 2 byte headers).  Since usb-serial only buffers 384 bytes of data,
usb-serial will pass in 6 64 byte blocks and 1 12 byte partial block for
462 bytes max.

f872c76296 stdvga+bochs-display: add dummy mmio handler
The bochs-display mmio bar has some sub-regions with the actual hardware
registers.  What happens when the guest access something outside those
regions depends on the archirecture.  On x86 those reads succeed (and
return 0xff I think).  On risc-v qemu aborts.

This patch adds handlers for the parent region, to make the wanted
behavior explicit and to make things consistent across architectures.

v2:
 - use existing unassigned_io_ops.
 - also cover stdvga.

6785aee00c hw/arm/virt: kvm: allow gicv3 by default if v2 cannot work
At the moment if the end-user does not specify the gic-version along
with KVM acceleration, v2 is set by default. However most of the
systems now have GICv3 and sometimes they do not support GICv2
compatibility.

This patch keeps the default v2 selection in all cases except
in the KVM accelerated mode when either
- the host does not support GICv2 in-kernel emulation or
- number of VCPUS exceeds 8.

Those cases did not work anyway so we do not break any compatibility.
Now we get v3 selected in such a case.

97b4c9188c hw/arm/virt: kvm: Restructure finalize_gic_version()
Restructure the finalize_gic_version with switch cases and
clearly separate the following cases:

- KVM mode / in-kernel irqchip
- KVM mode / userspace irqchip
- TCG mode

In KVM mode / in-kernel irqchip , we explictly check whether
the chosen version is supported by the host. If the end-user
explicitly sets v2/v3 and this is not supported by the host,
then the user gets an explicit error message. Note that for
old kernels where the CREATE_DEVICE ioctl doesn't exist then
we will now fail if the user specifically asked for gicv2,
where previously we (probably) would have succeeded.

In KVM mode / userspace irqchip we immediatly output an error
in case the end-user explicitly selected v3. Also we warn the
end-user about the unexpected usage of gic-version=host in
that case as only userspace GICv2 is supported.

d45efe4782 target/arm/kvm: Let kvm_arm_vgic_probe() return a bitmap
Convert kvm_arm_vgic_probe() so that it returns a
bitmap of supported in-kernel emulation VGIC versions instead
of the max version: at the moment values can be v2 and v3.
This allows to expose the case where the host GICv3 also
supports GICv2 emulation. This will be useful to choose the
default version in KVM accelerated mode.

a9ad9e73a7 hw/arm/allwinner: add RTC device support
Allwinner System-on-Chips usually contain a Real Time Clock (RTC)

Allwinner RTC device that supports the RTC devices found in Allwinner SoC
family sun4i (A10), sun7i (A20) and sun6i and newer (A31, H2+, H3, etc).
The following RTC functionality and features are implemented:

 * Year-Month-Day read/write
 * Hour-Minute-Second read/write
 * General Purpose storage

The following boards are extended with the RTC device:

 * Cubieboard (hw/arm/cubieboard.c)
 * Orange Pi PC (hw/arm/orangepi.c)

a80beb160d hw/arm/allwinner-h3: add Boot ROM support
A real Allwinner H3 SoC contains a Boot ROM which is the
first code that runs right after the SoC is powered on.
The Boot ROM is responsible for loading user code (e.g. a bootloader)
from any of the supported external devices and writing the downloaded
code to internal SRAM. After loading the SoC begins executing the code
written to SRAM.

This commits adds emulation of the Boot ROM firmware setup functionality
by loading user code from SD card in the A1 SRAM. While the A1 SRAM is
64KiB, we limit the size to 32KiB because the real H3 Boot ROM also rejects
sizes larger than 32KiB. For reference, this behaviour is documented
by the Linux Sunxi project wiki at:

e7e741ca9d aspeed/smc: Fix User mode select/unselect scheme
The Aspeed SMC Controller can operate in different modes : Read, Fast
Read, Write and User modes. When the User mode is configured, it
selects automatically the SPI slave device until the CE_STOP_ACTIVE
bit is set to 1. When any other modes are configured the device is
unselected. The HW logic handles the chip select automatically when
the flash is accessed through its AHB window.

When configuring the CEx Control Register, the User mode logic to
select and unselect the slave is incorrect and data corruption can be
seen on machines using two chips, witherspoon and romulus.

Rework the handler setting the CEx Control Register to fix this issue.

8c4985298f hw/intc/armv7m_nvic: Rebuild hflags on reset
Some of an M-profile CPU's cached hflags state depends on state that's
in our NVIC object. We already do an hflags rebuild when the NVIC
registers are written, but we also need to do this on NVIC reset,
because there's no guarantee that this will happen before the
CPU reset.

This fixes an assertion due to mismatched hflags which happens if
the CPU is reset from inside a HardFault handler.

0a01e082a4 s390/ipl: sync back loadparm
We expose loadparm as a r/w machine property, but if loadparm is set by
the guest via DIAG 308, we don't update the property. Having a
disconnect between the guest view and the QEMU property is not nice in
itself, but things get even worse for SCSI, where under certain
circumstances (see 789b5a401b "s390: Ensure IPL from SCSI works as
expected" for details) we call s390_gen_initial_iplb() on resets
effectively overwriting the guest/user supplied loadparm with the stale
value.
