linux-user: Add support for getting/setting selected alsa timer parameters using ioctls
This patch implements functionalities of following ioctls:
SNDRV_TIMER_IOCTL_INFO - Getting information about selected timer
Read information about the selected timer. The information is returned in
the following structure:
struct snd_timer_info {
unsigned int flags; /* timer flags - SNDRV_TIMER_FLG_* */
int card; /* card number */
unsigned char id[64]; /* timer identificator */
unsigned char name[80]; /* timer name */
unsigned long reserved0; /* reserved for future use */
unsigned long resolution; /* average period resolution in ns */
unsigned char reserved[64]; /* reserved for future use */
};
A pointer to this structure should be passed as the third ioctl's argument.
Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
called first to select the timer which information is to be obtained. If no
timer is selected, the error EBADFD ("File descriptor in bad shape") is
returned.
SNDRV_TIMER_IOCTL_PARAMS - Setting parameters for selected timer
Sets parameters for the selected timer. The paramaters are set in the
following structure:
struct snd_timer_params {
unsigned int flags; /* flags - SNDRV_TIMER_PSFLG_* */
unsigned int ticks; /* requested resolution in ticks */
unsigned int queue_size; /* total size of queue (32-1024) */
unsigned int reserved0; /* reserved, was: failure locations */
unsigned int filter; /* event filter */
unsigned char reserved[60]; /* reserved */
};
A pointer to this structure should be passed as the third ioctl's argument.
Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
called first to select the timer which parameters are to be set. If no
timer is selected, the error EBADFD ("File descriptor in bad shape") is
returned.
SNDRV_TIMER_IOCTL_STATUS - Getting status of selected timer
Read status of the selected timer. The status of the timer is returned in
the following structure:
struct snd_timer_status {
struct timespec tstamp; /* Timestamp - last update */
unsigned int resolution; /* current period resolution in ns */
unsigned int lost; /* counter of master tick lost */
unsigned int overrun; /* count of read queue overruns */
unsigned int queue; /* used queue size */
unsigned char reserved[64]; /* reserved */
};
A pointer to this structure should be passed as the third ioctl's argument.
Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
called first to select the timer which status is to be obtained. If no
timer is selected, the error EBADFD ("File descriptor in bad shape") is
returned.
Implementation notes:
All ioctls in this patch have pointer to some kind of a structure
as their third argument. That is the reason why corresponding
definitions were added in 'linux-user/syscall_types.h'. Structure
'snd_timer_status' has field of type 'struct timespec' which is why
a corresponding definition of that structure was also added in
'linux-user/syscall_types.h'. All of these strucutures have some
fields that are of type 'unsigned long'. That is the reason why
separate target structures were defined in 'linux-user/syscall_defs.h'.
Structure 'struct timespec' already had a separate target definition
so that definition was used to define a target structure for
'snd_timer_status'. The rest of the implementation was straightforward.

linux-user: Add support for getting alsa timer version and id
This patch implements functionalities of following ioctls:
SNDRV_TIMER_IOCTL_PVERSION - Getting the sound timer version
Read the sound timer version. The third ioctl's argument is
a pointer to an int in which the specified timers version
is returned.
SNDRV_TIMER_IOCTL_NEXT_DEVICE - Getting id information about next timer
Read id information about the next timer device from the sound timer
device list. The id infomration is returned in the following structure:
struct snd_timer_id {
int dev_class; /* timer device class number */
int dev_sclass; /* slave device class number (unused) */
int card; /* card number */
int device; /* device number */
int subdevice; /* sub-device number */
};
The devices in the sound timer device list are arranged by the fields
of this structure respectively (first by dev_class number, then by
card number, ...). A pointer to this structure should be passed as
the third ioctl's argument. Before calling the ioctl, the parameters
of this structure should be initialized in relation to the next timer
device which information is to be obtained. For example, if a wanted
timer device has the device class number equal to or bigger then 2,
the field dev_class should be initialized to 2. After the ioctl call,
the structure fields are filled with values from the next device in
the sound timer device list. If there is no next device in the list,
the structure is filled with "zero" id values (in that case all
fields are filled with value -1).
Implementation notes:
The ioctl 'SNDRV_TIMER_IOCTL_NEXT_DEVICE' has a pointer to a
'struct snd_timer_id' as its third argument. That is the reason why
corresponding definition is added in 'linux-user/syscall_types.h'.
Since all elements of this structure are of type 'int', the rest of
the implementation was straightforward.
The line '#include <linux/rtc.h>' was added to recognize
preprocessor definitions for these ioctls. This needs to be
done only once in this series of commits. Also, the content
of this file (with respect to ioctl definitions) remained
unchanged for a long time, therefore there is no need to
worry about supporting older Linux kernel version.

linux-user: Use `qemu_log' for strace
This change switches linux-user strace logging to use the newer `qemu_log`
logging subsystem rather than the older `gemu_log` (notice the "g")
logger. `qemu_log` has several advantages, namely that it allows logging
to a file, and provides a more unified interface for configuration
of logging (via the QEMU_LOG environment variable or options).
This change introduces a new log mask: `LOG_STRACE` which is used for
logging of user-mode strace messages.

Since most calls to `gemu_log` are actually logging unimplemented features,
this change replaces most non-strace calls to `gemu_log` with calls to
`qemu_log_mask(LOG_UNIMP, ...)`. This allows the user to easily log to
a file, and to mask out these log messages if they desire.

"unimplemented" log messages will not be logged by default.

qapi: Delete all the "foo: dropped in n.n" notes
A handful of QAPI doc comments include lines like
"ppcemb: dropped in 3.1". The doc comment parser will just
put these into whatever the preceding section was; sometimes
that's "Notes", and sometimes it's some random other section,
as with "NetClientDriver" where the "'dump': dropped in 2.12"
line ends up in the "Since:" section.
This tends to render wrongly, more so in the upcoming rST
generator, but sometimes even in the Texinfo, as in the case
of QKeyCode:
ac_bookmarks
since 2.10 altgr, altgr_r: dropped in 2.10
Since commit
3264ffced3 (v4.2.0), we have a better place to tell
users about deprecated and deleted functionality --
qemu-deprecated.texi. These "dropped in" remarks all predate it, and
other feature drops of that vintage are not documented anywhere, so
moving these to qemu-deprecated.texi makes little sense. Drop them
instead.

qapi/migration.json: Replace _this_ with *this*
The MigrationInfo::setup-time documentation is the only place where we
use _this_ inline markup for emphasis, commonly rendered in italics.
We would like to switch the doc comments to rST format, but rST
doesn't recognize that markup and emits literal underscores.
Switch to *this* instead. Changes markup to strong emphasis with
Texinfo, commonly rendered as bold. With rST, it will go right back
to emphasis / italics.
rST also uses **this** for strong (commonly rendered bold) where
Texinfo uses *this*. We have one place in the doc comments
which uses strong/bold markup, in qapi/introspect.json:
Note: the QAPI schema is also used to help define *internal*
When we switch to rST that will be rendered as emphasis / italics.
Markus (who wrote that) thinks that using emphasis / italics
there is an improvement, so we leave that markup alone.

qapi: Fix indent level on doc comments in json files
The current doc generation doesn't care much about indentation levels,
but we would like to switch to an rST format, and rST does care about
indentation.
Make the doc comments more strongly consistent about indentation
for multiline constructs like:
@arg: description line 1
description line 2
Returns: line one
line 2
so that there is always exactly one space after the colon, and
subsequent lines align with the first.
This commit is a purely whitespace change, and it does not alter the
generated .texi files (because the texi generation code strips away
all the extra whitespace). This does mean that we end up with some
over-length lines.
Note that when the documentation for an argument fits on a single
line like this:
@arg: one line only
then stray extra spaces after the ':' don't affect the rST output, so
I have not attempted to methodically fix them, though the preference
is a single space here too.

Strictly the Texinfo generated is still wrong because each line

generator, which otherwise complains about the inconsistent

qga/qapi-schema.json: minor format fixups for rST
We would like to switch the doc comments to rST format, and rST
requires a blank line before the start of a bulleted or enumerated
list. Two places in qapi-schema.json were missing this blank line.
Some places were using an indented line as a sort of single-item
bulleted list, which in the Texinfo output comes out all run
onto a single line; use a real bulleted list instead.
Some places unnecessarily indented lists, which confuses rST.
guest-fstrim:minimum's documentation was indented the
right amount to share a line with @minimum, but wasn't
actually doing so.
The indent on the bulleted list in the guest-set-vcpus
Returns section meant rST misindented it.
Changes to the generated Texinfo are very minor (the new
bulleted lists, and a few extra blank lines).

configure: Check that sphinx-build is using Python 3
Currently configure's has_sphinx_build() check simply runs a dummy
sphinx-build and either passes or fails. This means that "no
sphinx-build at all" and "sphinx-build exists but is too old" are
both reported the same way.
Further, we want to assume that all the Python we write is running
with at least Python 3.5; configure checks that for our scripts, but
Sphinx extensions run with whatever Python version sphinx-build
itself is using.
Add a check to our conf.py which makes sphinx-build fail if it would
be running our extensions with an old Python, and handle this
in configure so we can report failure helpfully to the user.
This will mean that configure --enable-docs will fail like this
if the sphinx-build provided is not suitable:
Warning: sphinx-build exists but it is either too old or uses too old a Python version
ERROR: User requested feature docs
configure was not able to find it.

RISC-V Patches for the 5.0 Soft Freeze, Part 2
This is a fairly light-weight pull request, but I wanted to send it out to
avoid the Goldfish stuff getting buried as the next PR should contain the H
extension implementation.
As far as this PR goes, it contains:
* The addition of syscon device tree nodes for reboot and poweroff, which
allows Linux to control QEMU without an additional driver. The existing
device was already compatible with the syscon interface.
* A fix to our GDB stub to avoid confusing XLEN and FLEN, specifically useful
for rv32id-based systems.
* A device emulation for the Goldfish RTC device, a simple memory-mapped RTC.
* The addition of the Goldfish RTC device to the RISC-V virt board.
This passes "make check" and boots buildroot for me.

target/arm: Implement ARMv8.1-VMID16 extension
The ARMv8.1-VMID16 extension extends the VMID from 8 bits to 16 bits:
* the ID_AA64MMFR1_EL1.VMIDBits field specifies whether the VMID is
8 or 16 bits
* the VMID field in VTTBR_EL2 is extended to 16 bits
* VTCR_EL2.VS lets the guest specify whether to use the full 16 bits,
or use the backwards-compatible 8 bits
For QEMU implementing this is trivial:
* we do not track VMIDs in TLB entries, so we never use the VMID field
* we treat any write to VTTBR_EL2, not just a change to the VMID field
bits, as a "possible VMID change" that causes us to throw away TLB
entries, so that code doesn't need changing
* we allow the guest to read/write the VTCR_EL2.VS bit already
So all that's missing is the ID register part: report that we support
VMID16 in our 'max' CPU.

hw/arm/raspi: Use BCM2708 machine type with pre Device Tree kernels
When booting without device tree, the Linux kernels uses the $R1
register to determine the machine type. The list of values is
registered at [1].
There are two entries for the Raspberry Pi:
- https://www.arm.linux.org.uk/developer/machines/list.php?mid=3138
name: MACH_TYPE_BCM2708
value: 0xc42 (3138)
status: Active, not mainlined
date: 15 Oct 2010
- https://www.arm.linux.org.uk/developer/machines/list.php?mid=4828
name: MACH_TYPE_BCM2835
value: 4828
status: Active, mainlined
date: 6 Dec 2013
QEMU always used the non-mainlined type MACH_TYPE_BCM2708.
The value 0xc43 is registered to 'MX51_GGC' (processor i.MX51), and
0xc44 to 'Western Digital Sharespace NAS' (processor Marvell
88F5182).
The Raspberry Pi foundation bootloader only sets the BCM2708 machine
type, see [2] or [3]:
133 9:
134 mov r0, #0
135 ldr r1, =3138 @ BCM2708 machine id
136 ldr r2, atags @ ATAGS
137 bx r4
U-Boot only uses MACH_TYPE_BCM2708 (see [4]):
25 /*
26 * 2835 is a SKU in a series for which the 2708 is the first or primary SoC,
27 * so 2708 has historically been used rather than a dedicated 2835 ID.
28 *
29 * We don't define a machine type for bcm2709/bcm2836 since the RPi Foundation
30 * chose to use someone else's previously registered machine ID (3139, MX51_GGC)
31 * rather than obtaining a valid ID:-/
32 *
33 * For the bcm2837, hopefully a machine type is not needed, since everything
34 * is DT.
35 */
While the definition MACH_BCM2709 with value 0xc43 was introduced in
a commit described "Add 2709 platform for Raspberry Pi 2" out of the
mainline Linux kernel, it does not seem used, and the platform is
introduced with Device Tree support anyway (see [5] and [6]).
Remove the unused values (0xc43 introduced in commit
1df7d1f9303aef
"raspi: add raspberry pi 2 machine" and 0xc44 in commit
bade58166f4
"raspi: Raspberry Pi 3 support"), keeping only MACH_TYPE_BCM2708.

arm/acpi: simplify the description of PCI _CRS

then returns the resource template object itself; the resulted output
is like below:
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Name (RBUF, ResourceTemplate ()

So the named object "RBUF" is actually useless. The more natural way
is to return RBUF instead, or simply drop RBUF definition.
Choose the latter one to simplify the code.
