This introduces a new tracing backend that targets the SystemTAP
implementation of DTrace userspace tracing. The core functionality
should be applicable and standard across any DTrace implementation
on Solaris, OS-X, *BSD, but the Makefile rules will likely need
some small additional changes to cope with OS specific build

This backend builds a little differently from the other tracing
backends. Specifically there is no 'trace.c' file, because the
'dtrace' command line tool generates a '.o' file directly from
the dtrace probe definition file. The probe definition is usually
named with a '.d' extension but QEMU uses '.d' files for its
external makefile dependancy tracking, so this uses '.dtrace' as
the extension for the probe definition file.
The 'tracetool' program gains the ability to generate a trace.h

the dtrace probe definition.
Example usage of a dtrace probe in systemtap looks like:

Intel HD Audio Controller, the PCI device. Provides a HDA bus.
Emulates ICH6 at the moment. Adding a ICH9 PCIE
variant shouldn't be hard.
hda-duplex
HDA Codec. Attaches to the HDA bus. Supports 16bit stereo,
rates 16k -> 96k, playback, recording and volume control
(with CONFIG_MIXEMU=y).
hda-output
HDA Codec without recording support. Subset of the hda-duplex
codec. Use this if you don't want your guests access your mic.
Usage: add '-device intel-hda -device hda-duplex' to your command line.
Tested guests:
* Linux works.
* Win7 works.
* DOS (mpxplay) works.
* WinXP doesn't work.
[ v2 changes ]
* Fixed endianess, big endian hosts work now.
* Fixed some emulation bugs.
* Added immediate command emulation.
* Added vmstate support.
* Make it behave like all other sound card drivers:
- can be configured via '--audio-card-list=hda'
- can be added to a VM using '-soundhw hda'
* Code style fixups.
* Zapped guest-triggerable asserts.
* Handle partial reads/writes of audio data correctly.

vl.c has a Sun-specific hack to supply a prototype for madvise(),
but the call site has apparently moved to arch_init.c.
Haiku doesn't implement madvise() in favor of posix_madvise().
OpenBSD and Solaris 10 don't implement posix_madvise() but madvise().
MinGW implements neither.
Check for madvise() and posix_madvise() in configure and supply qemu_madvise()
as wrapper. Prefer madvise() over posix_madvise() due to flag availability.
Convert all callers to use qemu_madvise() and QEMU_MADV_*.
Note that on Solaris the warning is fixed by moving the madvise() prototype,
not by qemu_madvise() itself. It helps with porting though, and it simplifies
most call sites.
v7 -> v8:
* Some versions of MinGW have no sys/mman.h header. Reported by Blue Swirl.
v6 -> v7:
* Adopt madvise() rather than posix_madvise() semantics for returning errors.
* Use EINVAL in place of ENOTSUP.
v5 -> v6:
* Replace two leftover instances of POSIX_MADV_NORMAL with QEMU_MADV_INVALID.
Spotted by Blue Swirl.
v4 -> v5:
* Introduce QEMU_MADV_INVALID, suggested by Alexander Graf.
Note that this relies on -1 not being a valid advice value.
v3 -> v4:
* Eliminate #ifdefs at qemu_advise() call sites. Requested by Blue Swirl.
This will currently break the check in kvm-all.c by calling madvise() with
a supported flag, which will not fail. Ideas/patches welcome.
v2 -> v3:
* Reuse the *_MADV_* defines for QEMU_MADV_*. Suggested by Alexander Graf.
* Add configure check for madvise(), too.
Add defines to Makefile, not QEMU_CFLAGS.
Convert all callers, untested. Suggested by Blue Swirl.
* Keep Solaris' madvise() prototype around. Pointed out by Alexander Graf.

Allow users to specify a file for trace-outputs at configuration.
Also, allow trace files to be annotated by <pid> so each qemu instance has
unique traces.
The trace file name can be passed as a config option:
--trace-file=/path/to/file
(Default: trace )
At runtime, the pid of the qemu process is appended to the filename so
that mutiple qemu instances do not have overlapping logs.
Eg : trace-1234 for qemu launched with pid 1234.
I have yet to test this on windows. getpid() is used at many places
in code(including vnc.c), so I'm hoping this would be okay too.

This patch adds support for dynamically enabling/disabling of trace events.
This is done by internally maintaining each trace event's state, and
permitting logging of data from a trace event only if it is in an
'active' state.
Monitor commands added :
1) info trace-events : to view all available trace events and
their state.
2) trace-event NAME on|off : to enable/disable data logging from a
given trace event.
Eg, trace-event paio_submit off
disables logging of data when
paio_submit is hit.
By default, all trace-events are disabled. One can enable desired trace-events
via the monitor.

This patch introduces the trace-events file where trace events can be
declared like so:
qemu_malloc(size_t size) "size %zu"
qemu_free(void *ptr) "ptr %p"
These trace event declarations are processed by a new tool called
tracetool to generate code for the trace events. Trace event
declarations are independent of the backend tracing system (LTTng User
Space Tracing, ftrace markers, DTrace).
The default "nop" backend generates empty trace event functions.
Therefore trace events are disabled by default.
The trace-events file serves two purposes:
1. Adding trace events is easy. It is not necessary to understand the
details of a backend tracing system. The trace-events file is a
single location where trace events can be declared without code
duplication.
2. QEMU is not tightly coupled to one particular backend tracing system.
In order to support tracing across QEMU host platforms and to
anticipate new backend tracing systems that are currently maturing,
it is important to be flexible and not tied to one system.

One of the most important missing feature in QMP today is its
supported commands documentation.
The plan is to make it part of self-description support, however
self-description is a big task we have been postponing for a
long time now and still don't know when it's going to be done.
In order not to compromise QMP adoption and make users' life easier,
this commit adds a simple text documentation which fully describes
all QMP supported commands.
This is not ideal for a number of reasons (harder to maintain,
text-only, etc) but does improve the current situation. To avoid at
least divering from the user monitor help and texi snippets, QMP bits
are also maintained inside qemu-monitor.hx, and hxtool is extended to
generate a single text file from them.

Cross SDL packages (or the user) now can simply set a link (for example

Historically the qemu tlb "addend" field was used for both RAM and IO accesses,
so needed to be able to hold both host addresses (unsigned long) and guest
physical addresses (target_phys_addr_t). However since the introduction of
the iotlb field it has only been used for RAM accesses.
This means we can change the type of addend to unsigned long, and remove
associated hacks in the big-endian TCG backends.
We can also remove the host dependence from target_phys_addr_t.

A few words about design choices:
* On IA64, instructions should be grouped by bundle, and dependencies
between instructions declared. A first version of this code tried to
schedule instructions automatically, but was very complex and too
invasive for the current common TCG code (ops not ending at
instruction boundaries, code retranslation breaking already generated
code, etc.) It was also not very efficient, as dependencies between
TCG ops is not available.
Instead the option taken by the current implementation does not try
to fill the bundle by scheduling instructions, but by providing ops
not available as an ia64 instruction, and by offering 22-bit constant
loading for most of the instructions. With both options the bundle are
filled at approximately the same level.
* Up to 128 registers can be affected to a function on IA64, but TCG
limits this number to 64, which is actually more than enough. The
register affectation is the following:
- r0: used to map a constant argument with value 0
- r1: global pointer
- r2, r3: internal use
- r4 to r6: not used to avoid saving them
- r7: env structure
- r8 to r11: free for TCG (call clobbered)
- r12: stack pointer
- r13: thread pointer
- r14 to r31: free for TCG (call clobbered)
- r32: reserved (return address)
- r33: reserved (PFS)
- r33 to r63: free for TCG
* The IA64 architecture has only 64-bit registers and no 32-bit
instructions (the only exception being cmp4). Therefore 64-bit
registers and instructions are used for 32-bit ops. The adopted
strategy is the same as the ABI, that is the higher 32 bits are
undefined. Most ops (and, or, add, shl, etc.) can directly use
the 64-bit registers, while some others have to sign-extend (sar,
div, etc.) or zero-extend (shr, divu, etc.) the register first.

Use kinfo_getvmmap(3) on FeeBSD >= 7.x and /compat/linux/proc on older
FreeBSD. (kinfo_getvmmap is preferred since /compat/linux/proc is
usually only mounted on hosts also using the Linuxolator.)
This patch is a bit hacky because the includes needed for kinfo_getvmmap
conflict with other definitions in exec.c by default so I had to `trick
around' a little, but I built the result in FreeBSD 6.4-stable and
7.2-stable tbs and on 8-stable on the host so the hacks at least
should be stable. (If this is a problem maybe we could also move the

linux-user build on fedora 11 breaks because fallocate
is broken on that system if -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64
are specified, which is what QEMU uses.
We do have a configure check to catch this and disable fallocate,
however, it turns out that default QEMU_CFLAGS/LDFLAGS were assigned in
script *after* all compiler checks: so during checks we were not running
compiler with same flags that we used for build later.
Fix this by moving QEMU_CFLAGS to before compiler checks, and using
comple_prog when checking for fallocate. This also fixes the fact that
we do some compiler checks while assigning the flags, right below a

useful for bswap and 64-bit ops.
* Most ops supports a constant argument with value 0, which is actually

* While the at register is available for constant loading, ops only
support a limited range of constants. TCG does a better job doing the
register allocation and constant loading by itself. There are plenty of

We have code for a quite a few block formats. While I trust that all
of these formats are useful at least for some people in some
circumstances, some of them are of a kind that friends don't let
friends use in production.
This patch provides an optional block format whitelist, default off.
If a whitelist is configured with --block-drv-whitelist, QEMU proper
can use only whitelisted formats. Other programs, like qemu-img, are
not affected.
Drivers for formats off the whitelist still participate in format
probing, to ensure all programs probe exactly the same. Without that,
QEMU proper would be prone to treat images with a format off the
whitelist as raw when the image's format is probed.

Now that do have a nicer interface to work against we can add Linux native
AIO support. It's an extremly thing layer just setting up an iocb for
the io_submit system call in the submission path, and registering an
eventfd with the qemu poll handler to do complete the iocbs directly
from there.
This started out based on Anthony's earlier AIO patch, but after
estimated 42,000 rewrites and just as many build system changes
there's not much left of it.
To enable native kernel aio use the aio=native sub-command on the
drive command line. I have also added an option to qemu-io to
test the aio support without needing a guest.

kqemu introduces a number of restrictions on the i386 target. The worst is that
it prevents large memory from working in the default build.
Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on
the TSC as a time source which will not be reliable on a multiple processor
system in userspace. Since most modern processors are multicore, this severely
limits the utility of kqemu.
kvm is a viable alternative for people looking to accelerate qemu and has the
benefit of being supported by the upstream Linux kernel. If someone can
implement work arounds to remove the restrictions introduced by kqemu, I'm
happy to avoid and/or revert this patch.
N.B. kqemu will still function in the 0.11 series but this patch removes it from
the 0.12 series.

Second attempt failed due to $_ not being standard and as such it's
interpretation by certain shells when they were symlinked to /bin/sh

--disable-gfx-check predates VNC server support. It made sense back then
because the only thing you could do without SDL was use -nographic mode or
similar tricks. Since this is a very advanced mode of operation, gfx-check
provided a good safety net for casual users.
A casual user is very likely to use VNC to interact with a guest. In fact, it's
often frustrating to install QEMU on a server and have to specify
disable-gfx-check when you only want to use VNC.
This patch eliminates disable-gfx-check and makes SDL behave like every other
optional dependency. If SDL is not available, instead of failing ungracefully
if no special options are specified, we default to -vnc localhost:0,to=99.
When we do default to VNC, we also print a message to tell the user that we've
done this include which port we're currently listening on.

This patch introduces a generic internal API for access control lists
to be used by network servers in QEMU. It adds support for checking
these ACL in the VNC server, in two places. The first ACL is for the
SASL authentication mechanism, checking the SASL username. This ACL
is called 'vnc.username'. The second is for the TLS authentication
mechanism, when x509 client certificates are turned on, checking against
the Distinguished Name of the client. This ACL is called 'vnc.x509dname'
The internal API provides for an ACL with the following characteristics
- A unique name, eg vnc.username, and vnc.x509dname.
- A default policy, allow or deny
- An ordered series of match rules, with allow or deny policy
If none of the match rules apply, then the default policy is
used.
There is a monitor API to manipulate the ACLs, which I'll describe via
examples
(qemu) acl show vnc.username
policy: allow
(qemu) acl policy vnc.username denya
acl: policy set to 'deny'
(qemu) acl allow vnc.username fred
acl: added rule at position 1
(qemu) acl allow vnc.username bob
acl: added rule at position 2
(qemu) acl allow vnc.username joe 1
acl: added rule at position 1
(qemu) acl show vnc.username
policy: deny
0: allow fred
1: allow joe
2: allow bob
(qemu) acl show vnc.x509dname
policy: allow
(qemu) acl policy vnc.x509dname deny
acl: policy set to 'deny'
(qemu) acl allow vnc.x509dname C=GB,O=ACME,L=London,CN=*
acl: added rule at position 1
(qemu) acl allow vnc.x509dname C=GB,O=ACME,L=Boston,CN=bob
acl: added rule at position 2
(qemu) acl show vnc.x509dname
policy: deny
0: allow C=GB,O=ACME,L=London,CN=*
1: allow C=GB,O=ACME,L=Boston,CN=bob
By default the VNC server will not use any ACLs, allowing access to
the server if the user successfully authenticates. To enable use of
ACLs to restrict user access, the ',acl' flag should be given when
starting QEMU. The initial ACL activated will be a 'deny all' policy
and should be customized using monitor commands.
eg enable SASL auth and ACLs
qemu .... -vnc localhost:1,sasl,acl
The next patch will provide a way to load a pre-defined ACL when
starting up

This patch adds the new SASL authentication protocol to the VNC server.
It is enabled by setting the 'sasl' flag when launching VNC. SASL can
optionally provide encryption via its SSF layer, if a suitable mechanism
is configured (eg, GSSAPI/Kerberos, or Digest-MD5). If an SSF layer is
not available, then it should be combined with the x509 VNC authentication
protocol which provides encryption.
eg, if using GSSAPI
qemu -vnc localhost:1,sasl
eg if using TLS/x509 for encryption
qemu -vnc localhost:1,sasl,tls,x509
By default the Cyrus SASL library will look for its configuration in
the file /etc/sasl2/qemu.conf. For non-root users, this can be overridden
by setting the SASL_CONF_PATH environment variable, eg to make it look in
$HOME/.sasl2. NB unprivileged users may not have access to the full range
of SASL mechanisms, since some of them require some administrative privileges
to configure. The patch includes an example SASL configuration file which
illustrates config for GSSAPI and Digest-MD5, though it should be noted that
the latter is not really considered secure any more.
Most of the SASL authentication code is located in a separate source file,
vnc-auth-sasl.c. The main vnc.c file only contains minimal integration
glue, specifically parsing of command line flags / setup, and calls to
start the SASL auth process, to do encoding/decoding for data.
There are several possible stacks for reading & writing of data, depending
on the combo of VNC authentication methods in use
- Clear. read/write straight to socket
- TLS. read/write via GNUTLS helpers
- SASL. encode/decode via SASL SSF layer, then read/write to socket
- SASL+TLS. encode/decode via SASL SSF layer, then read/write via GNUTLS
Hence, the vnc_client_read & vnc_client_write methods have been refactored
a little.
vnc_client_read: main entry point for reading, calls either
- vnc_client_read_plain reading, with no intermediate decoding
- vnc_client_read_sasl reading, with SASL SSF decoding
These two methods, then call vnc_client_read_buf(). This decides
whether to write to the socket directly or write via GNUTLS.
The situation is the same for writing data. More extensive comments
have been added in the code / patch. The vnc_client_read_sasl and
vnc_client_write_sasl method implementations live in the separate
vnc-auth-sasl.c file.
The state required for the SASL auth mechanism is kept in a separate
VncStateSASL struct, defined in vnc-auth-sasl.h and included in the
main VncState.
The configure script probes for SASL and automatically enables it
if found, unless --disable-vnc-sasl was given to override it.

The sysctl variable if we're 64-bit capable only exists on i386. So we should only check it if we're on i386.

Mac OS X 10.5 supports 64-bit userspace on an x86_64 kernel and
by default uses 32-bit userspace applications, so the detection for
the host architecture fails.
This patch enabled building of x86_64 code on x86_64 capable CPUS
with Mac OS X.

These files are nearly identical to the XML files provided with GDB.
The only difference is that power-{fpu,spe}.xml do not assign register
numbers; the internal QEMU machinery takes care of that.
Define gdb_xml_files for ppc targets in configure as well.

The patch applies to upstream qemu as well as kvm-userspace, but since it is
the qemu configure script I think it should go to upstream qemu (Anthony)
first and with the next merge to kvm-userspace. On the other hand it is the kvm
probe so an ack from Avi in case v3 is ok would be reasonable.
*updates*
v2 - it also reports other errors than just #error preprocessor statements
(requested by Avi)
v3 - In case awk or grep is not installed it now gracfully (silently)
fails still disabling kvm (requested by Anthony)
This patch is about reporting more details of the issue if configuring kvm
fails. Therefore this patch keeps the qemu style configure output which is a
list of "$Feature $Status", but extend the "no" result like "KVM Support no"
with some more information.
There might be a lot of things going wrong with that probe and I don't want
to handle all of them, but if it is one of the known checks e.g. for
KVM_API_VERSION then we could grep/awk that out and report it. The patch
reports in case of a known case in the style
"KVM support no - (Missing KVM capability KVM_CAP_DESTROY_MEMORY_REGION_WORKS)"
In case more than one #error is triggered it creates a comma separated list in
those brackets and in case it is something else than an #error it just reports
plain old "no".

There is already a variable kvm_cflags which gets the path of the kernel
includes when using --kerneldir. But eventually with newer kernels we all will
need arch/$arch/include too (my case was a incldue of asm/kvm.h which was not
found anymore). Headers in a full kernel source are not flattened to
one arch like they are if e.g. installed kernel headers are used.
To fix that, the includes added to cflags depending on --kerneldir should also
contian the arch includes. The patch adds a special check for x86 because its
source layout recently changed, all others directly use arch/$cpu/include if
existent.

We have been relying on uname to determine the host cpu architecture and
operating system. This is totally broken for cross compilation. It was
workable in the past because you can manually override both settings but after
the host USB passthrough refactoring, cross host builds were broken.
This moves the parsing of --cc and --cross-prefix to before the probes for cpu
and host. Complation testing is used to determine the host and CPU types. I've
only added checks for i386, x86_64, Linux, and Windows since these are the only
platforms I have access to for testing. Everything else falls back to uname.
It should be relatively easy to add the right checks for other platforms and
eliminate uname altogether.

Implement hooks called by generic KVM code.
Also add code that will copy the host's CPU and timebase frequencies to the
guest, which is necessary on KVM because the guest can directly access the
timebase.

To implement the -kernel, -initrd, and -append options, 4xx board emulation
must load the guest kernel as if firmware had loaded it. Where u-boot would be
the firmware, we must load the flat device tree into memory and set key fields
such as /chosen/bootargs.
This patch introduces a dependency on libfdt for flat device tree support.

This is really a stop-gap. The recent thread pool changes uncovered a
deeper issue with how we use librt. We really should be probing for
timer_create and then conditionally enabling that code.

glibc implements posix-aio as a thread pool and imposes a number of limitations.
1) it limits one request per-file descriptor. we hack around this by dup()'ing
file descriptors which is hideously ugly
2) it's impossible to add new interfaces and we need a vectored read/write
operation to properly support a zero-copy API.
What has been suggested to me by glibc folks, is to implement whatever new
interfaces we want and then it can eventually be proposed for standardization.
This requires that we implement our own posix-aio implementation though.
This patch implements posix-aio using pthreads. It immediately eliminates the
need for fd pooling.
It performs at least as well as the current posix-aio code (in some
circumstances, even better).

Prior to kvm-80, memory slot deletion was broken in the KVM kernel
modules. In kvm-81, a new capability is introduced to signify that this
problem has been fixed.
Since we rely on being able to delete memory slots, refuse to work with
any kernel module that does not have this capability present.
