2010-03-09Allow OR'able option valuesJens Axboe
Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2010-03-05Allow the adding of 'posval' for dynamic options like 'profile'Jens Axboe
Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2010-03-05Cleanup profile supportJens Axboe
This is closer to where it needs to end up. No ext_options, just include profile options in the general option table (and mark them private for that profile). Profile options are only available after loading a specific profile, so there should be less confusion. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2010-03-04Add initial support for profile specific optionsJens Axboe
Not complete yet, we need to split option parsing for profiles a bit. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2010-03-04Add parser support for out-of-td option storageJens Axboe
Currently the parser assumes the storage is inside a thread_data structure. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2010-03-04Add support for registrering external optionsJens Axboe
Start of support for real profiles. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2010-03-03Increase OPT_LEN_MAXZhang, Yanmin
When I run fio with lots of files on a disk, parameter filename's length is more than 1024 and tail filenames are cut. Below is a patch to increase OPT_LEN_MAX to 4096. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-07-18A few more kb_base fixupsJens Axboe
Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-07-01Add verify hook to optionsJens Axboe
This allows us to individually verify options, instead of having a big function that attempts to fix things up. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-06-09parser: get rid of FIO_OPT_STR_VAL_INTJens Axboe
It's treated the same as FIO_OPT_INT since we got rid of the int vs siint distinction. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-10-07Add environment-variable substitution to config optionsAaron Carroll
Strings of the form ${VARNAME} in config option strings are substituted with the value of the environment variable VARNAME. Only the right hand side of an option assignment undergoes substitution. If VARNAME is empty or undefined, the empty string is substituted. Signed-off-by: Aaron Carroll <aaronc@gelato.unsw.edu.au> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-06-10Add option prioritiesJens Axboe
For instance, filename= must come after directory= or things will go wrong. So add a priority value to each option, so that the parser will take that into account. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-04-07Mark rwmixcycle option as deprecated in the option parserJens Axboe
Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-12-14Add support for 'bssplit' option, fine grained block size contrlJens Axboe
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. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-31Be a little more clever in finding child optionsJens Axboe
We don't need ->parent_seen, just start from the next option. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-31Parent options didn't recurse properlyJens Axboe
It only displayed the first found. Add a ->parent_seen and find all matches. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-31Add parent link to optionsJens Axboe
Then we can nest display for --cmdhelp=all, to tie options together. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-03-14Add suboption help textsJens Axboe
Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-03-01Improve friendliness of --cmdhelpJens Axboe
If no match is found, print the closest. Quite handy when you can't quite remember the exact option name. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-02-23Move handling of possible values into the option parserJens Axboe
Eliminates the need for a callback for any FIO_OPT_STR type option, unless it needs to do something there other than just setting the variable. The possible options are not in an array of value pairs, so we can easily match an string option with an integer output value. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-01-11[PATCH] Change O_DIRECT vs buffered setupJens Axboe
Change the default from O_DIRECT IO to normal buffered IO. That makes more sense, as O_DIRECT is a special case and should be manually enabled as such. Do this by adding a option negate switch, so we don't need two sets of parameters to control these options. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-01-11[PATCH] Change timeout to runtime and rearrange option entriesJens Axboe
Runtime is a more descriptive name - the documentation is updated as well, however the parsing has added an alias functionality to support older names as well. So 'timeout' still works. Also rearrange option entries, now they matter because the --cmdhelp option will print them in order. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-01-10[PATCH] Option minval should be signedJens Axboe
Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-01-10[PATCH] Introduce bool option typeJens Axboe
We can automatically flag those with min/max values. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-01-10[PATCH] Show allowed option values for string matchingJens Axboe
Helpful to avoid looking in the documentation. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-01-10[PATCH] Fixup ratecycle optionJens Axboe
It set .name twice, the last one was supposed to be .help instead. Also kill options->opt_set, it's not used. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-01-10[PATCH] Add default option valuesJens Axboe
It's handy for the help text, and it also cleans up init.c by removing a bunch of default option defines. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-01-09[PATCH] Add per-option helpJens Axboe
It's hard to remember all the options that fio supports, so add a 'cmdhelp' option that either prints all possible options (if argument is 'all'), or specific option help (if argument is the command). Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2006-11-07[PATCH] Warn on writable stringsJens Axboe
Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2006-11-06[PATCH] bs= and bsrange= takes both read and write sizesJens Axboe
Get rid of read_bs/write_bs and read_bsrange/write_bsrange. It was ugly and too complicated. Instead support giving both values in a single bs= or bsrange= seperated by a comma. Example: bs=1k,4k will use 1k blocks for reads, 4k blocks for writes. bs=32k will use 32k blocks for both reads and writes. Similar for bsrange= Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2006-11-03[PATCH] Fix int vs long problems in parsing some optionsJens Axboe
The type needs to match strictly, or we get into problems on big endian architectures. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2006-10-27[PATCH] Add full command line parameter supportJens Axboe
You may now give full job options on the command line. Makes it easier to script fio or for one-off runs, as you don't have to write a job file and run that. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2006-10-27[PATCH] Abstract option handlingJens Axboe
Instead of parsing manually, we abstract out everything so parse.[ch] is now a generic config file parser. This is the next step towards unifying command and job options. I'm sure I broke plenty of options in the process... Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
