+TCG Plugins
+-----------
+
+QEMU TCG plugins provide a way for users to run experiments taking
+advantage of the total system control emulation can have over a guest.
+It provides a mechanism for plugins to subscribe to events during
+translation and execution and optionally callback into the plugin
+during these events. TCG plugins are unable to change the system state
+only monitor it passively. However they can do this down to an
+individual instruction granularity including potentially subscribing
+to all load and store operations.
+
+See the developer section of the manual for details about
+:ref:`writing plugins<TCG Plugins>`.
+
+Usage
+~~~~~
+
+Any QEMU binary with TCG support has plugins enabled by default.
+Earlier releases needed to be explicitly enabled with::
+
+  configure --enable-plugins
+
+Once built a program can be run with multiple plugins loaded each with
+their own arguments::
+
+  $QEMU $OTHER_QEMU_ARGS \
+      -plugin contrib/plugin/libhowvec.so,inline=on,count=hint \
+      -plugin contrib/plugin/libhotblocks.so
+
+Arguments are plugin specific and can be used to modify their
+behaviour. In this case the howvec plugin is being asked to use inline
+ops to count and break down the hint instructions by type.
+
+Linux user-mode emulation also evaluates the environment variable
+``QEMU_PLUGIN``::
+
+  QEMU_PLUGIN="file=contrib/plugins/libhowvec.so,inline=on,count=hint" $QEMU
+
+Example Plugins
+~~~~~~~~~~~~~~~
+
+There are a number of plugins included with QEMU and you are
+encouraged to contribute your own plugins plugins upstream. There is a
+``contrib/plugins`` directory where they can go. There are also some
+basic plugins that are used to test and exercise the API during the
+``make check-tcg`` target in ``tests/tcg/plugins`` that are never the
+less useful for basic analysis.
+
+Empty
+.....
+
+``tests/tcg/plugins/empty.c``
+
+Purely a test plugin for measuring the overhead of the plugins system
+itself. Does no instrumentation.
+
+Basic Blocks
+............
+
+``tests/tcg/plugins/bb.c``
+
+A very basic plugin which will measure execution in coarse terms as
+each basic block is executed. By default the results are shown once
+execution finishes::
+
+  $ qemu-aarch64 -plugin tests/plugin/libbb.so \
+      -d plugin ./tests/tcg/aarch64-linux-user/sha1
+  SHA1=15dd99a1991e0b3826fede3deffc1feba42278e6
+  bb's: 2277338, insns: 158483046
+
+Behaviour can be tweaked with the following arguments:
+
+.. list-table:: Basic Block plugin arguments
+  :widths: 20 80
+  :header-rows: 1
+
+  * - Option
+    - Description
+  * - inline=true|false
+    - Use faster inline addition of a single counter. Not per-cpu and not
+      thread safe.
+  * - idle=true|false
+    - Dump the current execution stats whenever the guest vCPU idles
+
+Instruction
+...........
+
+``tests/tcg/plugins/insn.c``
+
+This is a basic instruction level instrumentation which can count the
+number of instructions executed on each core/thread::
+
+  $ qemu-aarch64 -plugin tests/plugin/libinsn.so \
+      -d plugin ./tests/tcg/aarch64-linux-user/threadcount
+  Created 10 threads
+  Done
+  cpu 0 insns: 46765
+  cpu 1 insns: 3694
+  cpu 2 insns: 3694
+  cpu 3 insns: 2994
+  cpu 4 insns: 1497
+  cpu 5 insns: 1497
+  cpu 6 insns: 1497
+  cpu 7 insns: 1497
+  total insns: 63135
+
+Behaviour can be tweaked with the following arguments:
+
+.. list-table:: Instruction plugin arguments
+  :widths: 20 80
+  :header-rows: 1
+
+  * - Option
+    - Description
+  * - inline=true|false
+    - Use faster inline addition of a single counter.
+  * - sizes=true|false
+    - Give a summary of the instruction sizes for the execution
+  * - match=<string>
+    - Only instrument instructions matching the string prefix
+
+The ``match`` option will show some basic stats including how many
+instructions have executed since the last execution. For
+example::
+
+   $ qemu-aarch64 -plugin tests/plugin/libinsn.so,match=bl \
+       -d plugin ./tests/tcg/aarch64-linux-user/sha512-vector
+   ...
+   0x40069c, 'bl #0x4002b0', 10 hits, 1093 match hits, Δ+1257 since last match, 98 avg insns/match
+   0x4006ac, 'bl #0x403690', 10 hits, 1094 match hits, Δ+47 since last match, 98 avg insns/match
+   0x4037fc, 'bl #0x4002b0', 18 hits, 1095 match hits, Δ+22 since last match, 98 avg insns/match
+   0x400720, 'bl #0x403690', 10 hits, 1096 match hits, Δ+58 since last match, 98 avg insns/match
+   0x4037fc, 'bl #0x4002b0', 19 hits, 1097 match hits, Δ+22 since last match, 98 avg insns/match
+   0x400730, 'bl #0x403690', 10 hits, 1098 match hits, Δ+33 since last match, 98 avg insns/match
+   0x4037ac, 'bl #0x4002b0', 12 hits, 1099 match hits, Δ+20 since last match, 98 avg insns/match
+   ...
+
+For more detailed execution tracing see the ``execlog`` plugin for
+other options.
+
+Memory
+......
+
+``tests/tcg/plugins/mem.c``
+
+Basic instruction level memory instrumentation::
+
+  $ qemu-aarch64 -plugin tests/plugin/libmem.so,inline=true \
+      -d plugin ./tests/tcg/aarch64-linux-user/sha1
+  SHA1=15dd99a1991e0b3826fede3deffc1feba42278e6
+  inline mem accesses: 79525013
+
+Behaviour can be tweaked with the following arguments:
+
+.. list-table:: Memory plugin arguments
+  :widths: 20 80
+  :header-rows: 1
+
+  * - Option
+    - Description
+  * - inline=true|false
+    - Use faster inline addition of a single counter
+  * - callback=true|false
+    - Use callbacks on each memory instrumentation.
+  * - hwaddr=true|false
+    - Count IO accesses (only for system emulation)
+
+System Calls
+............
+
+``tests/tcg/plugins/syscall.c``
+
+A basic syscall tracing plugin. This only works for user-mode. By
+default it will give a summary of syscall stats at the end of the
+run::
+
+  $ qemu-aarch64 -plugin tests/plugin/libsyscall \
+      -d plugin ./tests/tcg/aarch64-linux-user/threadcount
+  Created 10 threads
+  Done

+
+Hot Blocks
+..........
+
+``contrib/plugins/hotblocks.c``
+
+The hotblocks plugin allows you to examine the where hot paths of
+execution are in your program. Once the program has finished you will
+get a sorted list of blocks reporting the starting PC, translation
+count, number of instructions and execution count. This will work best
+with linux-user execution as system emulation tends to generate
+re-translations as blocks from different programs get swapped in and
+out of system memory.
+
+If your program is single-threaded you can use the ``inline`` option for
+slightly faster (but not thread safe) counters.
+
+Example::
+
+  $ qemu-aarch64 \
+    -plugin contrib/plugins/libhotblocks.so -d plugin \
+    ./tests/tcg/aarch64-linux-user/sha1
+  SHA1=15dd99a1991e0b3826fede3deffc1feba42278e6
+  collected 903 entries in the hash table
+  pc, tcount, icount, ecount
+  0x0000000041ed10, 1, 5, 66087
+  0x000000004002b0, 1, 4, 66087
+  ...
+
+
+Hot Pages
+.........
+
+``contrib/plugins/hotpages.c``
+
+Similar to hotblocks but this time tracks memory accesses::
+
+  $ qemu-aarch64 \
+    -plugin contrib/plugins/libhotpages.so -d plugin \
+    ./tests/tcg/aarch64-linux-user/sha1
+  SHA1=15dd99a1991e0b3826fede3deffc1feba42278e6
+  Addr, RCPUs, Reads, WCPUs, Writes
+  0x000055007fe000, 0x0001, 31747952, 0x0001, 8835161
+  0x000055007ff000, 0x0001, 29001054, 0x0001, 8780625
+  0x00005500800000, 0x0001, 687465, 0x0001, 335857
+  0x0000000048b000, 0x0001, 130594, 0x0001, 355
+  0x0000000048a000, 0x0001, 1826, 0x0001, 11
+
+The hotpages plugin can be configured using the following arguments:
+
+.. list-table:: Hot pages arguments
+  :widths: 20 80
+  :header-rows: 1
+
+  * - Option
+    - Description
+  * - sortby=reads|writes|address
+    - Log the data sorted by either the number of reads, the number of writes, or
+      memory address. (Default: entries are sorted by the sum of reads and writes)
+  * - io=on
+    - Track IO addresses. Only relevant to full system emulation. (Default: off)
+  * - pagesize=N
+    - The page size used. (Default: N = 4096)
+
+Instruction Distribution
+........................
+
+``contrib/plugins/howvec.c``
+
+This is an instruction classifier so can be used to count different
+types of instructions. It has a number of options to refine which get
+counted. You can give a value to the ``count`` argument for a class of
+instructions to break it down fully, so for example to see all the system
+registers accesses::
+
+  $ qemu-system-aarch64 $(QEMU_ARGS) \
+    -append "root=/dev/sda2 systemd.unit=benchmark.service" \
+    -smp 4 -plugin ./contrib/plugins/libhowvec.so,count=sreg -d plugin
+
+which will lead to a sorted list after the class breakdown::
+
+  Instruction Classes:

+Lockstep Execution
+..................
+
+``contrib/plugins/lockstep.c``
+
+This is a debugging tool for developers who want to find out when and
+where execution diverges after a subtle change to TCG code generation.
+It is not an exact science and results are likely to be mixed once
+asynchronous events are introduced. While the use of -icount can
+introduce determinism to the execution flow it doesn't always follow
+the translation sequence will be exactly the same. Typically this is
+caused by a timer firing to service the GUI causing a block to end
+early. However in some cases it has proved to be useful in pointing
+people at roughly where execution diverges. The only argument you need
+for the plugin is a path for the socket the two instances will
+communicate over::
+
+
+  $ qemu-system-sparc -monitor none -parallel none \
+    -net none -M SS-20 -m 256 -kernel day11/zImage.elf \
+    -plugin ./contrib/plugins/liblockstep.so,sockpath=lockstep-sparc.sock \
+    -d plugin,nochain
+
+which will eventually report::

+Hardware Profile
+................
+
+``contrib/plugins/hwprofile.c``
+
+The hwprofile tool can only be used with system emulation and allows
+the user to see what hardware is accessed how often. It has a number of options:
+
+.. list-table:: Hardware Profile arguments
+  :widths: 20 80
+  :header-rows: 1
+
+  * - Option
+    - Description
+  * - track=[read|write]
+    - By default the plugin tracks both reads and writes. You can use
+      this option to limit the tracking to just one class of accesses.
+  * - source
+    - Will include a detailed break down of what the guest PC that made the
+      access was. Not compatible with the pattern option. Example output::
+
+        cirrus-low-memory @ 0xfffffd00000a0000
+         pc:fffffc0000005cdc, 1, 256
+         pc:fffffc0000005ce8, 1, 256
+         pc:fffffc0000005cec, 1, 256
+
+  * - pattern
+    - Instead break down the accesses based on the offset into the HW
+      region. This can be useful for seeing the most used registers of
+      a device. Example output::
+
+        pci0-conf @ 0xfffffd01fe000000
+          off:00000004, 1, 1
+          off:00000010, 1, 3
+          off:00000014, 1, 3
+          off:00000018, 1, 2
+          off:0000001c, 1, 2

+          ...
+
+
+Execution Log
+.............
+
+``contrib/plugins/execlog.c``
+
+The execlog tool traces executed instructions with memory access. It can be used
+for debugging and security analysis purposes.
+Please be aware that this will generate a lot of output.
+
+The plugin needs default argument::
+
+  $ qemu-system-arm $(QEMU_ARGS) \
+    -plugin ./contrib/plugins/libexeclog.so -d plugin
+
+which will output an execution trace following this structure::
+
+  # vCPU, vAddr, opcode, disassembly[, load/store, memory addr, device]...
+  0, 0xa12, 0xf8012400, "movs r4, #0"
+  0, 0xa14, 0xf87f42b4, "cmp r4, r6"
+  0, 0xa16, 0xd206, "bhs #0xa26"
+  0, 0xa18, 0xfff94803, "ldr r0, [pc, #0xc]", load, 0x00010a28, RAM
+  0, 0xa1a, 0xf989f000, "bl #0xd30"
+  0, 0xd30, 0xfff9b510, "push {r4, lr}", store, 0x20003ee0, RAM, store, 0x20003ee4, RAM
+  0, 0xd32, 0xf9893014, "adds r0, #0x14"
+  0, 0xd34, 0xf9c8f000, "bl #0x10c8"
+  0, 0x10c8, 0xfff96c43, "ldr r3, [r0, #0x44]", load, 0x200000e4, RAM
+
+Please note that you need to configure QEMU with Capstone support to get disassembly.
+
+The output can be filtered to only track certain instructions or
+addresses using the ``ifilter`` or ``afilter`` options. You can stack the
+arguments if required::
+
+  $ qemu-system-arm $(QEMU_ARGS) \
+    -plugin ./contrib/plugins/libexeclog.so,ifilter=st1w,afilter=0x40001808 -d plugin
+
+This plugin can also dump registers when they change value. Specify the name of the
+registers with multiple ``reg`` options. You can also use glob style matching if you wish::
+
+  $ qemu-system-arm $(QEMU_ARGS) \
+    -plugin ./contrib/plugins/libexeclog.so,reg=\*_el2,reg=sp -d plugin
+
+Be aware that each additional register to check will slow down
+execution quite considerably. You can optimise the number of register
+checks done by using the rdisas option. This will only instrument
+instructions that mention the registers in question in disassembly.
+This is not foolproof as some instructions implicitly change
+instructions. You can use the ifilter to catch these cases::
+
+  $ qemu-system-arm $(QEMU_ARGS) \
+    -plugin ./contrib/plugins/libexeclog.so,ifilter=msr,ifilter=blr,reg=x30,reg=\*_el1,rdisas=on
+
+Cache Modelling
+...............
+
+``contrib/plugins/cache.c``
+
+Cache modelling plugin that measures the performance of a given L1 cache
+configuration, and optionally a unified L2 per-core cache when a given working
+set is run::

+  $ qemu-x86_64 -plugin ./contrib/plugins/libcache.so \
+      -d plugin -D cache.log ./tests/tcg/x86_64-linux-user/float_convs
+
+will report the following::
+
+    core #, data accesses, data misses, dmiss rate, insn accesses, insn misses, imiss rate

+    0x4268a0 (__malloc), 696, andq $0xfffffffffffffff0, %rax
+    ...
+
+The plugin has a number of arguments, all of them are optional:
+
+.. list-table:: Cache modelling arguments
+  :widths: 20 80
+  :header-rows: 1
+
+  * - Option
+    - Description
+  * - limit=N
+    - Print top N icache and dcache thrashing instructions along with
+      their address, number of misses, and its disassembly. (default: 32)
+  * - icachesize=N
+      iblksize=B
+      iassoc=A
+    - Instruction cache configuration arguments. They specify the
+      cache size, block size, and associativity of the instruction
+      cache, respectively. (default: N = 16384, B = 64, A = 8)
+  * - dcachesize=N
+    - Data cache size (default: 16834)
+  * - dblksize=B
+    - Data cache block size (default: 64)
+  * - dassoc=A
+    - Data cache associativity (default: 8)
+  * - evict=POLICY
+    - Sets the eviction policy to POLICY. Available policies are:
+      ``lru``, ``fifo``, and ``rand``. The plugin will use
+      the specified policy for both instruction and data caches.
+      (default: POLICY = ``lru``)
+  * - cores=N
+    - Sets the number of cores for which we maintain separate icache
+      and dcache. (default: for linux-user, N = 1, for full system
+      emulation: N = cores available to guest)
+  * - l2=on
+    - Simulates a unified L2 cache (stores blocks for both
+      instructions and data) using the default L2 configuration (cache
+      size = 2MB, associativity = 16-way, block size = 64B).
+  * - l2cachesize=N
+    - L2 cache size (default: 2097152 (2MB)), implies ``l2=on``
+  * - l2blksize=B
+    - L2 cache block size (default: 64), implies ``l2=on``
+  * - l2assoc=A
+    - L2 cache associativity (default: 16), implies ``l2=on``
+
+Stop on Trigger
+...............
+
+``contrib/plugins/stoptrigger.c``
+
+The stoptrigger plugin allows to setup triggers to stop emulation.
+It can be used for research purposes to launch some code and precisely stop it
+and understand where its execution flow went.
+
+Two types of triggers can be configured: a count of instructions to stop at,
+or an address to stop at. Multiple triggers can be set at once.
+
+By default, QEMU will exit with return code 0. A custom return code can be
+configured for each trigger using ``:CODE`` syntax.
+
+For example, to stop at the 20-th instruction with return code 41, at address
+0xd4 with return code 0 or at address 0xd8 with return code 42::
+
+  $ qemu-system-aarch64 $(QEMU_ARGS) \
+    -plugin ./contrib/plugins/libstoptrigger.so,icount=20:41,addr=0xd4,addr=0xd8:42 -d plugin
+
+The plugin will log the reason of exit, for example::
+
+  0xd4 reached, exiting
+
+Other emulation features
+------------------------
+
+When running system emulation you can also enable deterministic
+execution which allows for repeatable record/replay debugging. See
+:ref:`Record/Replay<replay>` for more details.

 QEMU TCG Plugins
 ================
 
-QEMU TCG plugins provide a way for users to run experiments taking
-advantage of the total system control emulation can have over a guest.
-It provides a mechanism for plugins to subscribe to events during
-translation and execution and optionally callback into the plugin
-during these events. TCG plugins are unable to change the system state
-only monitor it passively. However they can do this down to an
-individual instruction granularity including potentially subscribing
-to all load and store operations.
-
-Usage
------
-
-Any QEMU binary with TCG support has plugins enabled by default.
-Earlier releases needed to be explicitly enabled with::
-
-  configure --enable-plugins
-
-Once built a program can be run with multiple plugins loaded each with
-their own arguments::
-
-  $QEMU $OTHER_QEMU_ARGS \
-      -plugin contrib/plugin/libhowvec.so,inline=on,count=hint \
-      -plugin contrib/plugin/libhotblocks.so
-
-Arguments are plugin specific and can be used to modify their
-behaviour. In this case the howvec plugin is being asked to use inline
-ops to count and break down the hint instructions by type.
-
-Linux user-mode emulation also evaluates the environment variable
-``QEMU_PLUGIN``::
-
-  QEMU_PLUGIN="file=contrib/plugins/libhowvec.so,inline=on,count=hint" $QEMU

-Example Plugins
-===============
-
-There are a number of plugins included with QEMU and you are
-encouraged to contribute your own plugins plugins upstream. There is a

-
-- tests/plugins/empty.c
-
-Purely a test plugin for measuring the overhead of the plugins system
-itself. Does no instrumentation.
-
-- tests/plugins/bb.c
-
-A very basic plugin which will measure execution in course terms as
-each basic block is executed. By default the results are shown once
-execution finishes::

-- contrib/plugins/hotblocks.c
-
-The hotblocks plugin allows you to examine the where hot paths of
-execution are in your program. Once the program has finished you will
-get a sorted list of blocks reporting the starting PC, translation
-count, number of instructions and execution count. This will work best
-with linux-user execution as system emulation tends to generate
-re-translations as blocks from different programs get swapped in and
-out of system memory.
-
-If your program is single-threaded you can use the ``inline`` option for
-slightly faster (but not thread safe) counters.
-
-Example::
-
-  $ qemu-aarch64 \
-    -plugin contrib/plugins/libhotblocks.so -d plugin \
-    ./tests/tcg/aarch64-linux-user/sha1
-  SHA1=15dd99a1991e0b3826fede3deffc1feba42278e6

-  0x0000000048a000, 0x0001, 1826, 0x0001, 11
-
-The hotpages plugin can be configured using the following arguments:
-
-  * sortby=reads|writes|address
-
-  Log the data sorted by either the number of reads, the number of writes, or
-  memory address. (Default: entries are sorted by the sum of reads and writes)
-
-  * io=on
-
-  Track IO addresses. Only relevant to full system emulation. (Default: off)
-
-  * pagesize=N
-
-  The page size used. (Default: N = 4096)
-
-- contrib/plugins/howvec.c
-
-This is an instruction classifier so can be used to count different

-To find the argument shorthand for the class you need to examine the

-
-- contrib/plugins/lockstep.c
-
-This is a debugging tool for developers who want to find out when and
-where execution diverges after a subtle change to TCG code generation.
-It is not an exact science and results are likely to be mixed once
-asynchronous events are introduced. While the use of -icount can
-introduce determinism to the execution flow it doesn't always follow
-the translation sequence will be exactly the same. Typically this is
-caused by a timer firing to service the GUI causing a block to end
-early. However in some cases it has proved to be useful in pointing
-people at roughly where execution diverges. The only argument you need
-for the plugin is a path for the socket the two instances will
-communicate over::
-
-
-  $ qemu-system-sparc -monitor none -parallel none \
-    -net none -M SS-20 -m 256 -kernel day11/zImage.elf \
-    -plugin ./contrib/plugins/liblockstep.so,sockpath=lockstep-sparc.sock \
-    -d plugin,nochain
-
-which will eventually report::
-
-  qemu-system-sparc: warning: nic lance.0 has no peer
-  @ 0x000000ffd06678 vs 0x000000ffd001e0 (2/1 since last)

-- contrib/plugins/hwprofile.c
-
-The hwprofile tool can only be used with system emulation and allows
-the user to see what hardware is accessed how often. It has a number of options:
-
- * track=read or track=write
-
- By default the plugin tracks both reads and writes. You can use one
- of these options to limit the tracking to just one class of accesses.
-
- * source
-
- Will include a detailed break down of what the guest PC that made the
- access was. Not compatible with the pattern option. Example output::
-
-   cirrus-low-memory @ 0xfffffd00000a0000
-    pc:fffffc0000005cdc, 1, 256
-    pc:fffffc0000005ce8, 1, 256
-    pc:fffffc0000005cec, 1, 256
-
- * pattern
-
- Instead break down the accesses based on the offset into the HW
- region. This can be useful for seeing the most used registers of a
- device. Example output::
-
-    pci0-conf @ 0xfffffd01fe000000
-      off:00000004, 1, 1
-      off:00000010, 1, 3
-      off:00000014, 1, 3
-      off:00000018, 1, 2

-- contrib/plugins/execlog.c
-
-The execlog tool traces executed instructions with memory access. It can be used
-for debugging and security analysis purposes.
-Please be aware that this will generate a lot of output.
-
-The plugin needs default argument::
-
-  $ qemu-system-arm $(QEMU_ARGS) \
-    -plugin ./contrib/plugins/libexeclog.so -d plugin
-
-which will output an execution trace following this structure::
-
-  # vCPU, vAddr, opcode, disassembly[, load/store, memory addr, device]...
-  0, 0xa12, 0xf8012400, "movs r4, #0"
-  0, 0xa14, 0xf87f42b4, "cmp r4, r6"
-  0, 0xa16, 0xd206, "bhs #0xa26"
-  0, 0xa18, 0xfff94803, "ldr r0, [pc, #0xc]", load, 0x00010a28, RAM
-  0, 0xa1a, 0xf989f000, "bl #0xd30"
-  0, 0xd30, 0xfff9b510, "push {r4, lr}", store, 0x20003ee0, RAM, store, 0x20003ee4, RAM
-  0, 0xd32, 0xf9893014, "adds r0, #0x14"
-  0, 0xd34, 0xf9c8f000, "bl #0x10c8"
-  0, 0x10c8, 0xfff96c43, "ldr r3, [r0, #0x44]", load, 0x200000e4, RAM
-
-Please note that you need to configure QEMU with Capstone support to get disassembly.
-
-The output can be filtered to only track certain instructions or
-addresses using the ``ifilter`` or ``afilter`` options. You can stack the
-arguments if required::
-
-  $ qemu-system-arm $(QEMU_ARGS) \
-    -plugin ./contrib/plugins/libexeclog.so,ifilter=st1w,afilter=0x40001808 -d plugin
-
-This plugin can also dump registers when they change value. Specify the name of the
-registers with multiple ``reg`` options. You can also use glob style matching if you wish::
-
-  $ qemu-system-arm $(QEMU_ARGS) \
-    -plugin ./contrib/plugins/libexeclog.so,reg=\*_el2,reg=sp -d plugin
-
-Be aware that each additional register to check will slow down
-execution quite considerably. You can optimise the number of register
-checks done by using the rdisas option. This will only instrument
-instructions that mention the registers in question in disassembly.
-This is not foolproof as some instructions implicitly change
-instructions. You can use the ifilter to catch these cases:
-
-  $ qemu-system-arm $(QEMU_ARGS) \
-    -plugin ./contrib/plugins/libexeclog.so,ifilter=msr,ifilter=blr,reg=x30,reg=\*_el1,rdisas=on
-
-- contrib/plugins/cache.c
-
-Cache modelling plugin that measures the performance of a given L1 cache
-configuration, and optionally a unified L2 per-core cache when a given working
-set is run::
-
-  $ qemu-x86_64 -plugin ./contrib/plugins/libcache.so \
-      -d plugin -D cache.log ./tests/tcg/x86_64-linux-user/float_convs
-
-will report the following::
-
-    core #, data accesses, data misses, dmiss rate, insn accesses, insn misses, imiss rate
-    0       996695         508             0.0510%  2642799        18617           0.7044%
-
-    address, data misses, instruction
-    0x424f1e (_int_malloc), 109, movq %rax, 8(%rcx)
-    0x41f395 (_IO_default_xsputn), 49, movb %dl, (%rdi, %rax)
-    0x42584d (ptmalloc_init.part.0), 33, movaps %xmm0, (%rax)
-    0x454d48 (__tunables_init), 20, cmpb $0, (%r8)
-    ...
-
-    address, fetch misses, instruction
-    0x4160a0 (__vfprintf_internal), 744, movl $1, %ebx
-    0x41f0a0 (_IO_setb), 744, endbr64
-    0x415882 (__vfprintf_internal), 744, movq %r12, %rdi
-    0x4268a0 (__malloc), 696, andq $0xfffffffffffffff0, %rax
-    ...
-
-The plugin has a number of arguments, all of them are optional:
-
-  * limit=N
-
-  Print top N icache and dcache thrashing instructions along with their
-  address, number of misses, and its disassembly. (default: 32)
-
-  * icachesize=N
-  * iblksize=B
-  * iassoc=A
-
-  Instruction cache configuration arguments. They specify the cache size, block
-  size, and associativity of the instruction cache, respectively.
-  (default: N = 16384, B = 64, A = 8)
-
-  * dcachesize=N
-  * dblksize=B
-  * dassoc=A
-
-  Data cache configuration arguments. They specify the cache size, block size,
-  and associativity of the data cache, respectively.
-  (default: N = 16384, B = 64, A = 8)
-
-  * evict=POLICY
-
-  Sets the eviction policy to POLICY. Available policies are: :code:`lru`,
-  :code:`fifo`, and :code:`rand`. The plugin will use the specified policy for
-  both instruction and data caches. (default: POLICY = :code:`lru`)
-
-  * cores=N
-
-  Sets the number of cores for which we maintain separate icache and dcache.
-  (default: for linux-user, N = 1, for full system emulation: N = cores
-  available to guest)
-
-  * l2=on
-
-  Simulates a unified L2 cache (stores blocks for both instructions and data)
-  using the default L2 configuration (cache size = 2MB, associativity = 16-way,
-  block size = 64B).
-
-  * l2cachesize=N
-  * l2blksize=B
-  * l2assoc=A
-
-  L2 cache configuration arguments. They specify the cache size, block size, and
-  associativity of the L2 cache, respectively. Setting any of the L2
-  configuration arguments implies ``l2=on``.
-  (default: N = 2097152 (2MB), B = 64, A = 16)
-
-- contrib/plugins/stoptrigger.c
-
-The stoptrigger plugin allows to setup triggers to stop emulation.
-It can be used for research purposes to launch some code and precisely stop it
-and understand where its execution flow went.
-
-Two types of triggers can be configured: a count of instructions to stop at,
-or an address to stop at. Multiple triggers can be set at once.
-
-By default, QEMU will exit with return code 0. A custom return code can be
-configured for each trigger using ``:CODE`` syntax.
-
-For example, to stop at the 20-th instruction with return code 41, at address
-0xd4 with return code 0 or at address 0xd8 with return code 42::
-
-  $ qemu-system-aarch64 $(QEMU_ARGS) \
-    -plugin ./contrib/plugins/libstoptrigger.so,icount=20:41,addr=0xd4,addr=0xd8:42 -d plugin
-
-The plugin will log the reason of exit, for example::
-
-  0xd4 reached, exiting
-

 Testing in QEMU
 ===============
 
-This document describes the testing infrastructure in QEMU.
+QEMU's testing infrastructure is fairly complex as it covers
+everything from unit testing and exercising specific sub-systems all
+the way to full blown acceptance tests. To get an overview of the
+tests you can run ``make check-help`` from either the source or build
+tree.
+
+Most (but not all) tests are also integrated into the meson build
+system so can be run directly from the build tree, for example:
+
+.. code::
+
+  [./pyvenv/bin/]meson test --suite qemu:softfloat
+
+will run just the softfloat tests.
+
+The rest of this document will cover the details for specific test
+groups.
 
 Testing with "make check"

-The "make check" testing family includes most of the C based tests in QEMU. For
