948770b0a7 hw/arm/bcm2835: Use object_initialize() on PL011State
To be coherent with the other peripherals contained in the
BCM2835PeripheralState structure, directly allocate the PL011State
(instead of using the pl011 uart as a pointer to a SysBusDevice).

Initialize the PL011State with object_initialize() instead of
object_new().

3d2fc923ec hw/virtio: Use object_initialize_child for correct reference counting
As explained in commit aff39be0ed:

  Both functions, object_initialize() and object_property_add_child()
  increase the reference counter of the new object, so one of the
  references has to be dropped afterwards to get the reference
  counting right. Otherwise the child object will not be properly
  cleaned up when the parent gets destroyed.
  Thus let's use now object_initialize_child() instead to get the
  reference counting here right.

This patch was generated using the following Coccinelle script:

 @use_object_initialize_child@
 expression parent_obj;
 expression child_ptr;
 expression child_name;
 expression child_type;
 expression child_size;
 expression errp;
 @@
 (
 -   object_initialize(child_ptr, child_size, child_type);
 +   object_initialize_child(parent_obj, child_name,  child_ptr, child_size,
 +                           child_type, &error_abort, NULL);
     ... when != parent_obj
 -   object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), NULL);
     ...

 -   object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), errp);
     ...
 ?-  object_unref(OBJECT(child_ptr));
 )

While the object_initialize() function doesn't take an
'Error *errp' argument, the object_initialize_child() does.
Since this code is used when a machine is created (and is not
yet running), we deliberately choose to use the &error_abort
argument instead of ignoring errors if an object creation failed.

e02bdf1cec qom/object: Display more helpful message when an object type is missing
When writing a new board, adding device which uses other devices
(container) or simply refactoring, one can discover the hard way
his machine misses some devices. In the case of containers, the
error is not obvious:

  $ qemu-system-microblaze -M xlnx-zynqmp-pmu
  **
  ERROR:/source/qemu/qom/object.c:454:object_initialize_with_type: assertion failed: (type != NULL)
  Aborted (core dumped)

And we have to look at the coredump to figure the error:

  (gdb) bt
  #1  0x00007f84773cf895 in abort () at /lib64/libc.so.6
  #2  0x00007f847961fb53 in  () at /lib64/libglib-2.0.so.0

  #8  0x000055c4bc95f6d2 in main (argc=<optimized out>, argv=<optimized out>, envp=<optimized out>) at /source/qemu/vl.c:4479

Since the caller knows the type name requested, we can simply display it
to ease development.

With this patch applied we get:

  $ qemu-system-microblaze -M xlnx-zynqmp-pmu
  qemu-system-microblaze: missing object type 'xlnx.zynqmp_ipi'
  Aborted (core dumped)

Since the assert(type) check in object_initialize_with_type() is
now impossible, remove it.

5f992db605 linux-user: Pass through nanosecond timestamp components for stat syscalls
Since Linux 2.6 the stat syscalls have mostly supported nanosecond
components for each of the file-related timestamps.

QEMU user mode emulation currently does not pass through the nanosecond
portion of the timestamp, even when the host system fills in the value.
This results in a mismatch when run on subsecond resolution filesystems
such as ext4 or XFS.

An example of this leading to inconsistency is cross-debootstraping a
full desktop root filesystem of Debian Buster. Recent versions of
fontconfig store the full timestamp (instead of just the second portion)
of the directory in its per-directory cache file, and checks this against
the directory to see if the cache is up-to-date. With QEMU user mode
emulation, the timestamp stored is incorrect, and upon booting the rootfs
natively, fontconfig discovers the mismatch, and proceeds to rebuild the
cache on the comparatively slow machine (low-power ARM vs x86). This
stalls the first attempt to open whatever application that incorporates
fontconfig.

This patch renames the "unused" padding trailing each timestamp element
to its nanosecond counterpart name if such an element exists in the
kernel sources for the given platform. Not all do. Then have the syscall
wrapper fill in the nanosecond portion if the host supports it, as
specified by the _POSIX_C_SOURCE and _XOPEN_SOURCE feature macros.

Recent versions of glibc only use stat64 and newfstatat syscalls on
32-bit and 64-bit platforms respectively. The changes in this patch
were tested by directly calling the stat, stat64 and newfstatat syscalls
directly, in addition to the glibc wrapper, on arm and aarch64 little
endian targets.

09380dd131 hw/intc/arm_gicv3: Fix writes to ICC_CTLR_EL3
The ICC_CTLR_EL3 register includes some bits which are aliases
of bits in the ICC_CTLR_EL1(S) and (NS) registers. QEMU chooses
to keep those bits in the cs->icc_ctlr_el1[] struct fields.
Unfortunately a missing '~' in the code to update the bits
in those fields meant that writing to ICC_CTLR_EL3 would corrupt
the ICC_CLTR_EL1 register values.

8b7fbd6c36 hw/intc/arm_gicv3: Fix write of ICH_VMCR_EL2.{VBPR0, VBPR1}
In ich_vmcr_write() we enforce "writes of BPR fields to less than
their minimum sets them to the minimum" by doing a "read vbpr and
write it back" operation.  A typo here meant that we weren't handling
writes to these fields correctly, because we were reading from VBPR0
but writing to VBPR1.

The header file hw/arm/arm.h now includes only declarations
relating to hw/arm/boot.c functionality. Rename it accordingly,
and adjust its header comment.

The bulk of this commit was created via
 perl -pi -e 's|hw/arm/arm.h|hw/arm/boot.h|' hw/arm/*.c include/hw/arm/*.h

In a few cases we can just delete the #include:
hw/arm/msf2-soc.c, include/hw/arm/aspeed_soc.h and
include/hw/arm/bcm2836.h did not require it.

04da973501 hw/nvram/fw_cfg: Store 'reboot-timeout' as little endian
The current codebase is not specific about the endianess of the
fw_cfg 'file' entry 'reboot-timeout'.

Per docs/specs/fw_cfg.txt:

  === All Other Data Items ===

  Please consult the QEMU source for the most up-to-date
  and authoritative list of selector keys and their respective
  items' purpose, format and writeability.

Checking the git history, this code was introduced in commit
ac05f34924, very similar to commit 3d3b8303c6 for the
'boot-menu-wait' entry, which explicitely use little-endian.

OVMF consumes 'boot-menu-wait' as little-endian, however it does
not consume 'reboot-timeout'.

Regarding the git history and OVMF use, we choose to explicit
'reboot-timeout' endianess as little-endian.

7a44091d48 tests: refactor fw_cfg_test
Currently, fw_cfg_test uses one QTestState for every test case.
This will add all command lines for every test case and
this is unnecessary. This patch split the test cases and for
every test case it uses his own QTestState. This patch does following
things:

1. Get rid of the global 'fw_cfg', this need add a uninit function

2. Convert every test case in a separate QTestState

After this patch, we can add fw_cfg test case freely and will not
have effect on other test cases.

11e2bfef79 tcg/i386: Use MOVDQA for TCG_TYPE_V128 load/store
This instruction raises #GP, aka SIGSEGV, if the effective address
is not aligned to 16-bytes.

We have assertions in tcg-op-gvec.c that the offset from ENV is
aligned, for vector types <= V128.  But the offset itself does not
validate that the final pointer is aligned -- one must also remember
to use the QEMU_ALIGNED() attribute on the vector member within ENV.

PowerPC Altivec has vector load/store instructions that silently
discard the low 4 bits of the address, making alignment mistakes
difficult to discover.  Aid that by making the most popular host
visibly signal the error.
