Change b296b664ab "smbus: Add a helper to generate SPD EEPROM

Add a QAuthZList object type that implements the QAuthZ interface. This
built-in implementation maintains a trivial access control list with a
sequence of match rules and a final default policy. This replicates the
functionality currently provided by the qemu_acl module.
To create an instance of this object via the QMP monitor, the syntax
used would be:
{
"execute": "object-add",
"arguments": {
"qom-type": "authz-list",
"id": "authz0",
"props": {
"rules": [
{ "match": "fred", "policy": "allow", "format": "exact" },
{ "match": "bob", "policy": "allow", "format": "exact" },
{ "match": "danb", "policy": "deny", "format": "glob" },
{ "match": "dan*", "policy": "allow", "format": "exact" },
],
"policy": "deny"
}
}
}
This sets up an authorization rule that allows 'fred', 'bob' and anyone
whose name starts with 'dan', except for 'danb'. Everyone unmatched is
denied.
It is not currently possible to create this via -object, since there is
no syntax supported to specify non-scalar properties for objects. This
is likely to be addressed by later support for using JSON with -object,
or an equivalent approach.
In any case the future "authz-listfile" object can be used from the
CLI and is likely a better choice, as it allows the ACL to be refreshed
automatically on change.

The current qemu_acl module provides a simple access control list
facility inside QEMU, which is used via a set of monitor commands
acl_show, acl_policy, acl_add, acl_remove & acl_reset.
Note there is no ability to create ACLs - the network services (eg VNC
server) were expected to create ACLs that they want to check.
There is also no way to define ACLs on the command line, nor potentially
integrate with external authorization systems like polkit, pam, ldap
lookup, etc.
The QAuthZ object defines a minimal abstract QOM class that can be
subclassed for creating different authorization providers.

The inotify userspace API for reading events is quite horrible, so it is
useful to wrap it in a more friendly API to avoid duplicating code
across many users in QEMU. Wrapping it also allows introduction of a
platform portability layer, so that we can add impls for non-Linux based
equivalents in future.

This is very convenient for people like me who store their QEMU git trees
on gitlab.com: Automatic CI pipelines are now run for each branch that is
pushed to the server - useful for some extra-testing before sending PULL-

jobs are distributed into multiple pipelines - this way everything finishs
fine within time (ca. 30 minutes currently).

The SSE-200 has a CPU_IDENTITY register block, which is a set of
read-only registers. As well as the usual PID/CID registers, there
is a single CPUID register which indicates whether the CPU is CPU 0
or CPU 1. Implement a model of this register block.

Move the complexity of milkymist_tmu2_create() into the
source file. Doing so we avoid to include the X11/OpenGL
headers in all LM32 devices, and we also avoid the duplicate
declaration of glx_fbconfig_attr[] (it is already declared
in hw/display/milkymist-tmu2.c).
Since TYPE_MILKYMIST_TMU2 is now accessible, use it.

The dtrace systemtap trace backend for QEMU is very powerful but it is
also somewhat unfriendly to users who aren't familiar with systemtap,
or who don't need its power right now.
stap -e "....some strange script...."
The 'log' backend for QEMU by comparison is very crude but incredibly
easy to use:
$ qemu -d trace:qio* ...some args...

This commit introduces a way to do simple printf style logging of probe
points using systemtap. In particular it creates another set of tapsets,
one per emulator:
/usr/share/systemtap/tapset/qemu-*-log.stp
These pre-define probe functions which simply call printf() on their
arguments. The printf() format string is taken from the normal
trace-events files, with a little munging to the format specifiers
to cope with systemtap's more restrictive syntax.
With this you can now do
$ stap -e 'probe qemu.system.x86_64.log.qio*{}'

22806@1547735341399976816 qio_task_thread_run Task thread run task=0x56135cd66eb0
We go one step further though and introduce a 'qemu-trace-stap' tool to
make this even easier
$ qemu-trace-stap run qemu-system-x86_64 'qio*'
22806@1547735341399856820 qio_channel_socket_new Socket new ioc=0x56135d1d7c00
22806@1547735341399862570 qio_task_new Task new task=0x56135cd66eb0 source=0x56135d1d7c00 func=0x56135af746c0 opaque=0x56135bf06400

22806@1547735341399976816 qio_task_thread_run Task thread run task=0x56135cd66eb0
This tool is clever in that it will automatically change the
SYSTEMTAP_TAPSET env variable to point to the directory containing the
right set of probes for the QEMU binary path you give it. This is useful
if you have QEMU installed in /usr but are trying to test and trace a
binary in /home/berrange/usr/qemu-git. In that case you'd do
$ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*'
And it'll make sure /home/berrange/usr/qemu-git/share/systemtap/tapset
is used for the trace session
The 'qemu-trace-stap' script takes a verbose arg so you can understand
what it is running
$ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*'
Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64'
Compiling script 'probe qemu.system.x86_64.log.qio* {}'
Running script, <Ctrl>-c to quit
...trace output...
It can enable multiple probes at once
$ qemu-trace-stap run qemu-system-x86_64 'qio*' 'qcrypto*' 'buffer*'
By default it monitors all existing running processes and all future
launched proceses. This can be restricted to a specific PID using the
--pid arg
$ qemu-trace-stap run --pid 2532 qemu-system-x86_64 'qio*'
Finally if you can't remember what probes are valid it can tell you
$ qemu-trace-stap list qemu-system-x86_64
ahci_check_irq
ahci_cmd_done
ahci_dma_prepare_buf
ahci_dma_prepare_buf_fail
ahci_dma_rw_buf
ahci_irq_lower
...snip...
Or list just those matching a prefix pattern
$ qemu-trace-stap list -v qemu-system-x86_64 'qio*'
Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64'
Listing probes with name 'qemu.system.x86_64.log.qio*'
qio_channel_command_abort
qio_channel_command_new_pid
qio_channel_command_new_spawn
qio_channel_command_wait
qio_channel_file_new_fd

I have made many significant contributions to the Xen code in QEMU,
particularly the recent patches introducing a new PV device framework.
I intend to make further significant contributions, porting other PV back-
ends to the new framework with the intent of eventually removing the
legacy code. It therefore seems reasonable that I become a maintainer of
the Xen code.
