Peter Maydell 41742927ee hw/i2c/bitbang_i2c: Use in-place rather than malloc'd bitbang_i2c_interface struct
Currently the bitbang_i2c_init() function allocates a
bitbang_i2c_interface struct which it returns.  This is unfortunate
because it means that if the function is used from a DeviceState
init method then the memory will be leaked by an "init then delete"
cycle, as used by the qmp/hmp commands that list device properties.

Since three out of four of the uses of this function are in
device init methods, switch the function to do an in-place
initialization of a struct that can be embedded in the
device state struct of the caller.

This fixes LeakSanitizer leak warnings that have appeared in the
patchew configuration (which only tries to run the sanitizers
for the x86_64-softmmu target) now that we use the bitbang-i2c
code in an x86-64 config.

Mark Cave-Ayland 09340f497e sunhme: ensure that RX descriptor ring overflow is indicated to client driver
On very busy networks connected via a tap interface, it is possible to overflow
the RX descriptor ring in the time between the client driver enabling the RX
MAC and finishing writing the final configuration to the NIC registers.

Ensure that we detect this condition and update the status register accordingly
to indicate an overflow has occurred (and the incoming packet dropped) in order
to prevent the client driver becoming confused.

Commit 6807874d55 "sun4m: obey -vga none" changed the sun4m machines so that
they could be started without a framebuffer installed, but as no default
display type was configured the machines would start in headless mode without
an explict -vga option.

start with a framebuffer if one is not specifically requested.

Here's my next pull request for qemu-4.1.  I'm not sure if this will
 squeak in just before the soft freeze, or just after.  I don't think
 it really matters - most of this is bugfixes anyway.  There's some
 cleanups which aren't stictly bugfixes, but which I think are safe
 enough improvements to go in the soft freeze.  There's no true feature
 work.
 
 Unfortunately, I wasn't able to complete a few of my standard battery
 of pre-pull tests, due to some failures that appear to also be in
 master.  I'm hoping that hasn't missed anything important in here.
 
 Highlights are:
   * A number of fixe and cleanups for the XIVE implementation
   * Cleanups to the XICS interrupt controller to fit better with the new
     XIVE code
   * Numerous fixes and improvements to TCG handling of ppc vector
     instructions
   * Remove a number of unnnecessary #ifdef CONFIG_KVM guards
   * Fix some errors in the PCI hotplug paths
   * Assorted other fixes

Aleksandar Markovic 64ce541c0b linux-user: Handle EXCP_FPE properly for MIPS
Handle EXCP_FPE properly for MIPS in cpu loop.

Note that a vast majority of FP instructions are not affected by
the absence of the code in this patch, as they use alternative code
paths for handling floating point exceptions (see, for example,
invocations of update_fcr31()) - they rely on softfloat library for
keeping track on exceptions that needs to be raised. However, there
are few MIPS FP instructions (an example is CTC1) that use function
do_raise_exception() directly, and they need the case that is added
in this patch to propagate the FPE exception as designed.

The code is based on kernel's function force_fcr31_sig() in
arch/mips/kernel.traps.c.

Aleksandar Markovic 1272a6c488 linux-user: Introduce TARGET_HAVE_ARCH_STRUCT_FLOCK
Bring target_flock definitions to be more in sync with the way
flock is defined in kernel.

Basically, the rules from the kernel are:

1. Majority of architectures have a common flock definition.

2. Architectures with 32-bit MIPS ABIs have a sligtly different
flock definition; those architectures are the only arcitectures
that have HAVE_ARCH_STRUCT_FLOCK defined, and that preprocessor
constant is used in the common header as a flag for including or
not including common flock definition.

3. Sparc architectures also have a sligtly different flock
definition, but the difference is only the padding at the end of
the structure. The presence of that padding is determined by
preprocessor constants __ARCH_FLOCK6_PAD and __ARCH_FLOCK64_PAD.

QEMU linux-user already implements rules 1. and 3. in a very
similar way as they are implemented in kernel. However, rule 2.
is implemented in a dissimilar way (for example, the constant
TARGET_HAVE_ARCH_STRUCT_FLOCK is missing), and this patch brings
QEMU implementation much closer to the kernel implementation.
TARGET_HAVE_ARCH_STRUCT_FLOCK64 constant is also introduced to
mimic HAVE_ARCH_STRUCT_FLOCK64 from kernel, but it is not defined
anywhere, however, this is the case with HAVE_ARCH_STRUCT_FLOCK64
in kernel as well.

Aleksandar Markovic bf9136722c linux-user: Fix target_flock structure for MIPS O64 ABI
Among MIPS ABIs, only MIPS O32 and N32 have special (different
than other architectures) definition of structure flock in kernel.

Bring target_flock definition in QEMU for MIPS O64 ABI to the
correct state, which is currently different than the most common
definition, and it should actually be the same.

Jim Wilson d42744fe04 linux-user: Add support for strace for statx() syscall
All of the flags need to be conditional as old systems don't have
statx support.  Otherwise it works the same as other stat family
syscalls.  This requires the pending patch to add statx support.

Tested on Ubuntu 16.04 (no host statx) and Ubuntu 19.04 (with host
statx) using a riscv32-linux toolchain.

Aleksandar Rikalo efa921845c linux-user: Add support for translation of statx() syscall
Implement support for translation of system call statx().

The implementation is based on "best effort" approach: if host
is capable of executing statx(), host statx() is used. If not,
the implementation includes invoking a more mature system call
fstatat() on the host side to achieve as close as possible
functionality.

Support for statx() in kernel and glibc was, however, introduced
at different points of time (the difference is more than a year):

  - kernel: Linux 4.11 (30 April 2017)
  - glibc: glibc 2.28 (1 Aug 2018)

In this patch, the availability of statx() support is established
via __NR_statx (if it is defined, statx() is considered available).
This coincedes with statx() introduction in kernel.

However, the structure statx definition may not be available in
any header for hosts with glibc older than 2.28 (and it is, by
design, to be defined in one of glibc headers), even though the
full statx() functionality may be supported in kernel. Hence, a
structure "target_statx" is defined in this patch, to remove that
dependency on glibc headers, and to use statx() functionality as
soon as the host kernel is capable of supporting it. Such statx
structure definition is used for both target and host structures
statx (of course, this doesn't mean the endian arrangement is
the same on target and host - the endian conversion is done in
all necessary cases).

Philippe Mathieu-Daudé a6b1625d61 hw/mips: Express dependencies of the Jazz machine with Kconfig
The Jazz use the RC4030 Asic to provide an EISA bus and DMA/IRQ.
The framebuffer display is managed by a G364, the network card is
a Sonic DP83932. A QLogic ESP216 provides a SCSI bus.

None, for the both machine variants (PICA-61 and Magnum 4000),
the DP83932 chipset is soldered on the board, and is MMIO-mapped
(selected via Chip Select). Therefore we have to enforce the
'select' Kconfig rule (we can not use the 'imply' rule helpful
when devices are connected on a bus).
