options: ensure that we check all candidates on is_set check
We can have multiple options that touch the same variable. One
example is cpus_allowed or cpumask, both will set the same
backend variable. But if we set cpumask= and later check if
cpus_allowed is set, then we want that to report true.
This breaks certain options since b2a9e6496494.

Add support for verify triggers and verify state saving
This allows you to (for instance) instantly terminate a verify
write workload, and then later that everything was written
correctly up to that very point. This can be useful for testing
powercut scenarios, which is often problematic on storage
devices.
The trigger part is a file based notification scheme, similar
to what is provided for the status dumps. When triggered,
fio will exit immediately and write the verify state safely
to disk. A trigger can be accompanied by a trigger command.
Say you wanted to test powercut safety, the trigger could be
something that immediately cut power to the machine.
The verify state is either saved locally (if run locally),
or saved over the network if run in client/server mode.

Avoid buildenv conditional in thread_option struct
Managed to run into issues with an external ioengine
which got build with CONFIG_LIBNUMA not defined. Fio
itself got build with CONFIG_LIBNUMA this resulted
in different struct members offsets in the two different
ELF objects. Causing crashes due to invalidate offsets
inside the thread_data structure (e.g. td->io_ops->data).
Ideally all structs which might be used by external
ioengines should be independent of buildenv conditionals
like CONFIG_LIBNUMA or others.
Removed the CONFIG_LIBNUMA in thread_options.h and replaced
the libnuma specific "struct bitmask" members with strings
which hold the option's input value. This should also make
the marshaling/demarshaling in cconv.c easier.
(Note: the NUMA bits are not handled in cconv.c at the
moment. And not part of the thread_options_packed struct)

fio: add multi directory support
This patch adds support for ':' seperated multiple directories at the
directory config statement in order to achieve an automatic distribution
of job clones (numjob) across directories.
That way people can distribute a load across these directories (usually
mount points of disks) automatically - changing numjob will be
sufficient to get all job clones evenly (optimal if dirs % numjobs = 0,
otherwise as good as possible) distributed at all times.
To avoid confused users old config Files will behave like they always
did, old fio binaries using new config files won't abort but just use
the first specified dir. If one specifies an explcit (non generated)
filename the distribution to many directories is also deactivated.
It also fixes an issue of events seeming out of order like when running
with --debug=file seeing the "..." message meaning "I created the
clones" prior to the last clone activities. Now the clones are called
with index N-1 .. 1, zero being the base thread as before.

fio: provide an option for a startdelay range
This patch allows the specification of start delay as range. With a
range each thread will chose an individual startdelay out of the range.
That solves an issue of startdelay being the same for each numjob clone
and that way spreads all kind of activities e.g. that all clones with
mixed r/w jobs switch r/w at the same time. Also all kind of other
"thundering herd" issues can be softened by some time spread due to this
option.

Enfore that lockfile= must precede filename=
The way fio parses options, we need to have the file locking
defined before we start adding files. Normally we can handle
this with option priorities, but that doesn't work across
job section boundaries. So catch this case and error out,
otherwise fio will segfault when it attempts to unlock files
at the end of a job.

fio: consolidate rand_seed to uint64_t

While they are used differently, the places where they overlap
should reference the same type. This patch makes three of them the same
as suggested by Jens Axboe.

Juan Casse <jcasse@chromium.org> |
Adds verify_only option
When this option is set, a dry run (no actual io is performed) of the
workload will be done in order to compute the numberio for each block
header without overwriting the data on disk. Then, do_verify() will be
effectively verifying data that was written in a previous fio run.
In the case that "loops" is set to more than 1, do_verify() will delay
the verification of numberio to the last iteration when the same
numberio state that would have been written to disk in a previous
fio run has been reached.

Add options to have fio latency profile a device
This adds three new options:
- latency_target. This defines a specific latency target, in usec.
- latency_window. This defines the period over which fio samples.
- latency_percentile. This defines the percentage of IOs that must
meet the criteria specified by latency_target/latency_window.
With these options set, fio will run the described workload and
vary the queue depth between 1 and iodepth= to find the best
performing spot that meets the criteria specified by the three
options.
A sample job file is also added to demonstrate how to use this.

Add support for O_ATOMIC
O_ATOMIC makes writes atomic, meaning that they are fully stable
on media (in the event of a power cut) when acknowledged by the
device and OS.
This only truly works on Linux with the pending patches to
add O_ATOMIC.
Updated by Jens to:
- Add man page and HOWTO description of the option
- Make O_ATOMIC imply O_DIRECT, so that it actually works if you
don't set O_DIRECT manually.
- Add the option to the conversion list so it works for
client/server.
- Error handling so that if atomic=1 is set and the OS does not
support it, error out instead of just pretending it works.

To reproduce:
$ cat job.fio

$ fio --showcmd job.fio
fio: /x is not a directory
fio: failed parsing directory=/x
fio: job global dropped

Add support for modifying the randomness of a workload
Fio supports random or sequential IO, or random IO with a number of
sequential IOs in between. The percentage_random options allows
more fine grained control over this. It defaults to 100, which would
make any random workload still purely random. If set below 100,
there will be some percentage of sequential IOs. This happens randomly,
but at the specified percentages.
The percentage_sequential option is just the complement of that, it
is guaranteed that:
percentage_sequential + percentage_random == 100%
The later setting has priority, each will adjust the other.

Pre-load and sort random blocks for pure read verify workloads
If fio is run with a write phase before a read phase and the
IO type is random, the end read verify phase will get sorted
blocks to read back. But if fio is asked to verify something
that was previously randomly written, it will generate the
same random offsets in random order and verify those. This is
usually much slower than a sorted read back.
So add a verifysort_nr option that allows the user to specify
a number of random offsets to pre-generate and sort, before
reading them and verifying the contents. This greatly speeds
up pure read verify workloads.
Default to 1024, and put a max of 64K entries on the option.
We do a merge list sort on the entries, so we don't want a
huge amount of backlog.

Add check for invariant TSC on x86 and use TSC is default clock if reliable
TSC is by far the fastest clock we can use. Check the CPUID bits for
whether it is both constant rate AND synced across cores. If it is,
we can use it as our default clock source.
Fio will default to this clock source on x86 if no other clock source
is specifically given with clocksource= in the job file.

Add sample zipf distribution randomizer
Instead of just doing purely random IO where each block is
touched exactly (or close to, depending on random map) once,
add a zipf distribution scheme where a selectable theta
defines the spread and frequency of blocks read/written.
Committing this so I don't lose it. Needs a few changes,
for instance we need to hash the zipf output so that
the spread doesn't always just favor the lower LBA range.

options: get rid of more .cb option usage we don't need
- The lat/bw/iops log does not need two ways of storing whether
they are enabled or not. Just change the option to a string
storing variant, and use the existance of a filename to see
if it's set or not.
- The trim_percentage option need not have a callback, the
parser knows the limits and can store it appropriately.
- The verify_offset option can express it's minimum value
directly, it doesn't need a callback to set it on its own.

New offset_increment option
This patch adds a new option to fio job files. It is described
in the HOWTO as follows:
offset_increment=int If this is provided, then the real offset becomes
the offset + offset_increment * thread_number, where the
thread number is a counter that starts at 0 and is incremented
for each job. This option is useful if there are several jobs
which are intended to operate on a file in parallel in disjoint
segments, with even spacing between the starting points.

Token-based flow control
This patch allows two fio jobs to be kept to a certain
proportion of each other using token-based flow control.
There are three new parameters: flow, flow_watermark, and
flow_sleep, documented in the fio options. An example of an fio
job using these parameters is below:
[global]
norandommap
thread
time_based
runtime=30
direct=1
ioengine=libaio
iodepth=256
size=100g
bs=8k
filename=/tmp/testfile
flow_watermark=100
flow_sleep=1000
[job2]
numjobs=1
rw=write
flow=-8
[job1]
numjobs=1
rw=randread
flow=1
The motivating application of this patch was to allow random reads
and sequential writes at a particular given proportion.
This initial version is only correct when run with 'thread', as shared
state is represented with a global variable. It also only allows two
jobs to be synchronized properly. A future version might do more, but
no more functionality was needed for my application.
Tested: Ran a few fio jobs with this flow control, observing
the proportion of IOPS to match what was intended by the job file.
Varied the flow_watermark and flow_sleep parameters and observed
the effect on throughput.

Optimize pattern verify
Similar to the patch last week, this optimizes the pattern verify
operation to use optimized library calls like memcmp(), and only fall
back to byte-by-byte if there is a miscompare to locate it.
This uses the same premise that the pattern is repeated as many times
as possible to do large compares in a single call. For single byte
pattern, the setup fills the pattern space, and verify assumes it is
full.
Tested by running a script which created an 8k file with 4k bs and,
one byte at a time, tried corrupting the pattern and running a read
pass and verified it still found miscompares across the whole range of
the pattern. This was done with a pattern length of 1 and 3 bytes.
In performance tests, this was about 8 times more efficient on
verifies than without this patch.

Optimize pattern filling by limiting small calls to memcpy
In looking at profiling the speed of fill_pattern(), it calls memcpy()
for the fill pattern repeatedly for multibyte patterns. So for a 4
byte pattern with 8k IO, it calls memcpy() 2048 times.
Since there is already 512 bytes reserved for the pattern, I figured a
simple solution was to use it. This patch replicates short patterns
so they can be more efficiently copied. (Single byte patterns are
left alone since they can make use of the much more efficient memset()
call.)
The result is a 10x performance improvement on pattern filling. (With
this patch, it's still 3x slower than when it re-uses the already
filled pattern.)

implement zoned random I/O testing support
This fixes the limitation that prevents fio from doing random I/O with zones
enabled.
This also adds a 'zonerange' configuration option which may be too ambiguous
and is subject to potential renaming in the future.
When doing random I/O, it is beneficial to be able to specify how large the
addressible space is in the zone, while specifying a different metric for
how much data to read from that zone (i.e., how many samples to take from each
zone). When 'zonerange' is not specified, it defaults to be equal to the
'zonesize' option. When both are specified, 'zonerange' indicates the
size of the zone while 'zonesize' indicates the quantity of data to read from
each zone.

By default, fio will note an entry in the bw/iops/lat logs for every

average the results logged over 1 second instead. This reduces the

Private parameters for ioengines
Here is the polished version of the engine private options patch. As
discussed, the global section only ever tracks the private options for
the globally defined ioengine. For command line parameters, the
ioengine must be selected before any private options are used. (IE
--ioengine=libaio --userspace_reap will work, but --userspace_reap
--ioengine=libaio will not.)
The userspace_reap option from libaio has been moved over to this new
option method, usage should be identical to before.
The net ioengine has been modified to use parameters, with hostname,
port, protocol and listen defined as ioengine private parameters. The
old style of hostname=host,port,protocol no longer works, so usage
will need to be updated. (It will spit out an error that should be
clear enough that it changed if this is tried.) Also, with the new
way for specifying parameters, the net IO engine now allows data to
flow in either direction on TCP connections, regardless of which end
initiates the connection.
There's also a new command line argument --enghelp which can be used
to get help on ioengine private parameters, similar to --cmdhelp.
With no argument, it lists all built-in ioengine. The argument is an
ioengine name (Or path to .so) and optionally a comma followed by a
command name, which behaves identically to --cmdhelp.
For ioengine authorship, if options are supplied, both the options
structure and the size of the storage needed must be supplied, and the
storage must be large enough to hold a pointer to struct thread_data;
that is because the options callback doesn't explicitly have a pointer
to the thread data (Normally it relies on the fact that the options
struct is the start of the thread data), so the offset 0 of the struct
must point to the thread data, and is filled in automatically. (This
also neatly provides a guarantee that offset 0 is reserved in the
options data, so it can be safely used as a test of undefined.)

Cleanup option keyword/environment substitution
Right now the substitution for options seems quite fragile. Among the
issues...
- If bc had an error and returned no output, it caused a NULL reference
- Multiple variable substitutions (For example $ncpus * $pagesize)
caused an error as it tried to run bc after the first, with the second
still text
- Memory leak for every keyword substituted
- Multiplication caused shell wildcard expansion (*) of the current
directory when passing the input to bc
- Shell escape sequences would be parsed on the command line when bc is called
- Potential buffer overrun due to unchecked lengths on the input line
So I did a little cleanup to get rid of the issues. This patch also
moves the environment variable substitution to run before the keyword
substitution, so an environment variable can now indirectly perform a
keyword substitution.

Adding userspace_libaio_reap option
When a single thread is reading from a libaio io_context_t object
in a non-blocking polling manner (that is, with the minimum number
of events to return being 0), then it is possible to safely read
events directly from user-space, taking advantage of the fact that
the io_context_t object is a pointer to memory with a certain layout.
This patch adds an option, userspace_libaio_reap, which allows
reading events in this manner when the libaio engine is used.
You can observe its effect by setting iodepth_batch_complete=0
and seeing the change in distribution of system/user time based on
whether this new flag is set. If userspace_libaio_reap=1, then
busy polling takes place in userspace, and there is a larger amount of
usr CPU. If userspace_libaio_reap=0 (the default), then there is a
larger amount of sys CPU from the polling in the kernel.
Polling from a queue in this manner is several times faster. In my
testing, it took less than an eighth as much time to execute a
polling operation in user-space than with the io_getevents syscall.

For sequential IO, it is now possible to add a number of bytes to
be skipped for every block read or written. Using:
bs=8k
rw=read:8k
will first read 0k->8k, then 16k->24k, and so on. This skips 8k
for every 'bs' sized block read. Similar for writes, doing
bs=4k
rw=write:4k
will write 0k->4k, then 8k->12k, etc. End result being that every
other block is written, in a sequential fashion.

Add ability to invoke fallocate() FALLOC_FL_KEEP_SIZE.
Linux offers fallocate() and the FALLOC_FL_KEEP_SIZE option as
an alternative to posix_fallocate(). When FALLOC_FL_KEEP_SIZE is
specified for an falloc request going beyond the end of the file,
the requested blocks get preallocated without changing the apparent
size of the file. This is is a commonly recommended use of fallocate()
for workloads performing append writes.
This patch modifies the fallocate option from a boolean option
to a string option accepting none/posix/keep/0/1. 'keep' is only
made available on systems where FALLOC_FL_KEEP_SIZE is available
(i.e., Linux at this time). If specified, fallocate() is used
with FALLOC_FL_KEEP_SIZE set. 'none' disables pre-allocation while
'posix' uses posix_fallocate(). The default behavior remains unchaned,
i.e., invoking posix_fallocate. The settings '0'/'1' are there to
provide backward compatibility for users who had explicitly set the
boolean option.

Add support for simple profile benchmarks
One of the reasons that tiobench gets used a lot, is that you
simply have to run it. For "real" benchmarks, you usually
have to configure them first. This adds support for easy testing
by adding some predefined and included workloads. This commit
includes tiobench, to run a tiobench like workload you would
simply do:
$ fio --profile=tiobench
and that would be it.

Support > 4 byte verify write patterns
This is the patch I have to write/read/verify hex patterns of size > 4
bytes. I have tested these on hard drives and did not see any
performance change. I am assuming the performance drop if any might show
up in the read phase for probably solid state drives and maybe it can be
worked around using the asynchronous verify flag.

Fix bug in bssplit parsing
I found a bug is bssplit parsing in bssplit_ddir() when trying to use
FIO on an ARM platform. It looks like str_to_decimal() takes a "void
*" as its fourth argument, which it passes to get_multi_bytes(), which
is passes to fio_get_kb_base(), which casts it to a "struct
thread_data *". bssplit_ddir() is passing in "struct thread_data **",
which I think is causing fio_get_kb_base() to go paw around in the
stack; I believe the different stack layouts between ARM and x86 is
causing me to see this problem. The first change that introduces this
bug seems to be d6978a3242daad9cb7b0710b724f19225d1ed7e2.

Add support for different weights for reads and writes with bssplit
You can now do:
bssplit=4k/20:8k/80,1k/50:4k/50
To have 20% 4k reads and 80% 8k reads, while having 50% 1k writes
and 50% 4k writes. This is identical to how the bs= option treats
reads and writes.

Similar to what real life products sometimes do, offload gettimeofday()

Allow ranges of CPUs in cpus_allowed option
For a larger number of CPUs, it's a bit of a bother having to set
each one individually. Plus, you typically want to bind to a range of
CPUs, to keep the job core local (or whatever your preference). So extend
cpus_allowed to take ranges of CPU numbers as well. Now you can do:
cpus_allowed=0-7
and have your job confined to CPUs 0 through 7.

Sometimes it's useful to let a job settle for a little while
before taking any measurements on latency and throughput, since
the initial rate on eg a write workload may be much higher than
the longer sustained rate.
So add a ramp_time option that allows the user to specify a lead
ramp time that must have passed before fio takes any performance
numbers into account.

Revamp file locking
Get rid of the semaphore implementation, no need to carry both.
Add different locking modes (exclusive and readwrite) to enable
a wider range of testing. Also combine lockfile and lockfile_batch,
the latter is now a postfix option to the former.
So to enable readers-excluding-writers locking mode with a lock batch
count of 4, you would write:
lockfile=readwrite:4

Add support for 'bssplit' option, fine grained block size contrl
From the HOWTO addition:
bssplit=str Sometimes you want even finer grained control of the
block sizes issued, not just an even split between them.
This option allows you to weight various block sizes,
so that you are able to define a specific amount of
block sizes issued. The format for this option is:
bssplit=blocksize/percentage:blocksize/percentage
for as many block sizes as needed. So if you want to define
a workload that has 50% 64k blocks, 10% 4k blocks, and
40% 32k blocks, you would write:
bssplit=4k/10:64k/50:32k/40
Ordering does not matter. If the percentage is left blank,
fio will fill in the remaining values evenly. So a bssplit
option like this one:
bssplit=4k/50:1k/:32k/
would have 50% 4k ios, and 25% 1k and 32k ios. The percentages
always add up to 100, if bssplit is given a range that adds
up to more, it will error out.

Fix header_interval minimum value
It doesn't make sense to have a value of header size or less, since
then there's no room for actual data. Fio even crashes with a value
less than the header size.
Lets just make the minimum twice the header size, seems reasonable...

[PATCH] Offset verification header by a user-specified distance
Offset verification header by user specified distance.
- Implementation is somewhat simple and probably not ideal but it works. The
header is just swapped with the bytes at offset after the chunk has been
filled during populate. Everything is swapped back before verify.
- Also fixes a bug where we were relying on a moving pointer for increment
size in populate_verify_io_u (which was working until this patch).
- Also cleans up a couple smalls things from the header_interval patch.

Add cpus_allowed option
cpumask can be cumbersome to use, since it requires you to calculate

the affinity mask for CPUS 1, 3, and 8.
