print_syscall_err() relies on the sign of the returned value to know
if it is an errno value or not.
But in some cases the returned value can have the most signicant bit
set without being an errno.
This patch restores previous behaviour that was also checking if
we can decode the errno to validate it.
This patch fixes this kind of problem (qemu-m68k):
root@sid:/# QEMU_STRACE= ls
3 brk(NULL) = -1 errno=21473607683 uname(0x407fff8a) = 0
to become:
root@sid:/# QEMU_STRACE= ls
3 brk(NULL) = 0x8001e000
3 uname(0xffffdf8a) = 0

errno of the target is returned as a negative value by the syscall,
not in the host errno variable.
The emulation of the target syscall can return an error while the
host doesn't set an errno value. Target errnos and host errnos can
also differ in some cases.

The end address calculation for NA4 mode is wrong because the address
used isn't shifted.
It doesn't watch 4 bytes but a huge range because the end address
calculation is wrong.
The solution is to use the shifted address calculated for start address
variable.
Modifications are tested on Zephyr OS userspace test suite which works
for other RISC-V boards (E31 and E34 core).

OpenSBI is the default firmware in Qemu and has various firmware loading
options. Currently, qemu loader uses fw_jump which has a compile time
pre-defined address where fdt & kernel image must reside. This puts a
constraint on image size of the Linux kernel depending on the fdt location
and available memory. However, fw_dynamic allows the loader to specify
the next stage location (i.e. Linux kernel/U-Boot) in memory and other
configurable boot options available in OpenSBI.
Add support for OpenSBI dynamic firmware loading support. This doesn't
break existing setup and fw_jump will continue to work as it is. Any
other firmware will continue to work without any issues as long as it
doesn't expect anything specific from loader in "a2" register.

Currently, the fdt is copied to the ROM after the reset vector. The firmware
has to copy it to DRAM. Instead of this, directly copy the device tree to a
pre-computed dram address. The device tree load address should be as far as
possible from kernel and initrd images. That's why it is kept at the end of
the DRAM or 4GB whichever is lesser.

Problem with g_get_host_name() is that on the first call it saves
the hostname into a global variable and from then on, every
subsequent call returns the saved hostname. Even if the hostname
changes. This doesn't play nicely with guest agent, because if
the hostname is acquired before the guest is set up (e.g. on the
first boot, or before DHCP) we will report old, invalid hostname.

Invoking a series of freeze and thaw commands may result in QGA failing to stop
VSS Provider service as "COM+ System Application service" is stopped, which can
cause some delay in qga response.
In this commit StopService function was changed and VSS Provider service is now

In new functions print_ioctl() and print_syscall_ret_ioctl(), we don't

The only user (iotest 205) of QemuIoInteractive provides -f argument,
so it's a bit inefficient to use qemu_io_args, which contains -f too.
And we are going to add one more test, which wants to specify -f by
hand. Let's use qemu_io_args_no_fmt.

Blindly setting FD_CLOEXEC without a read-modify-write will
inadvertently clear any other intentionally-set bits, such as a
proposed new bit for designating a fd that must behave in 32-bit mode.
Use our wrapper function instead of an incorrect hand-rolled version.

When snprintf returns the same value as the buffer size, the final
byte was truncated to ensure a NUL terminator. Fortunately, such long
export names are unusual enough, with no real impact other than what
is displayed to the user.

Since added in commit 2bea128c3d, each SDHCI is wired with a SD
card, using empty card when no block drive provided. This is not
the desired behavior. The SDHCI exposes a SD bus to plug cards
on, if no card available, it is fine to have an unplugged bus.
Avoid creating unnecessary SD card device when no block drive
provided.

Replace the free-floating set of IRQs and palmte_onoff_gpios()
function with a simple QOM device that encapsulates this
behaviour.
This fixes Coverity issue CID 1421944, which points out that
the memory returned by qemu_allocate_irqs() is leaked.

Message-id: 20200628214230.2592-2-peter.maydell@linaro.org
Currently we have a free-floating set of IRQs and a function
tosa_out_switch() which handle the GPIO lines on the tosa board which
connect to LEDs, and another free-floating IRQ and tosa_reset()
function to handle the GPIO line that resets the system. Encapsulate
this behaviour in a simple QOM device.
This commit fixes Coverity issue CID 1421929 (which pointed out that
the 'outsignals' in tosa_gpio_setup() were leaked), because it
removes the use of the qemu_allocate_irqs() API from this code
entirely.

wrctl instruction on nios2 target will cause checking cpu
interrupt but tcg_handle_interrupt() will call cpu_abort()
if the CPU gets an interrupt while it's not in 'can do IO'
state, so add gen_io_start around wrctl instruction. Also
at the same time, end the onging TB with DISAS_UPDATE.
