FWTS(1)

NAME
fwts - a firmware test suite to identify firmware bugs.

SYNOPSIS
fwts [options] [test(s)]

DESCRIPTION
This manual page documents briefly the fwts firmware test suite. The tool fwts is comprised of over fifty tests that are designed to examine and test different aspects of PC firmware. Many of these tests need super user access to extract tables and interact with the firmware and ACPI, so running fwts using sudo is required.
Running fwts with no options will run through all the batch tests that require no user interaction. However, one can select just specific tests to run if required.

By default fwts outputs the test results into the log file results.log however a different log file name can be specified and if required, output to stderr or stdout can be selected.

Note that there a variety of tests, including tests that can potentially hang a machine (such as a suspend/hibernate/resume).

OPTIONS
fwts options are as follow:

-   output results to stdout.

--acpica
    enable ACPICA execution mode options. These can be specified as a comma separated list of one or more options. Avaiable options are: serialized (serialized execution of AML), slack (run in less pedeantic mode), ignore-errors (ignore ACPICA exception errors), disable-auto-repair (disable ACPICA from automatically fixing broken ACPICA controls). Note that the slack mode will turn on implicit returns of zero on control methods to attempt to allow buggy AML to work on non-Windows systems.

--acpica-debug
    enable ACPICA debug warning and error messages when invoking the ACPICA subsystem. This is mainly for fwts developers to help track down any ACPICA interfacing issues with fwts.

-a, --all
    run all the tests.

-b, --batch
    run the non-interactive batch tests. Batch tests require no user interaction.

--batch-experimental
    run only batch experimental tests.

--disassemble-aml
    Disassemble AML (ACPI machine language) byte code. This attempts to disassemble AML in DSDT and SSDT tables and generates DSDT.dsl and SSDTx.dsl sources.

-d, --dump
    extracts firmware data and dumps it into log files. This generates:
    acpidump.log - containing a hex dump of the ACPI tables (which can be read using acpixtract).
    dmesg.log - containing the current kernel log messages.
    dmidecode.log - containing the output from dmidecode.
    lspci.log - containing the output from lspci -vv -nn
    README.txt - containing a timestamp and kernel version information.

--dumpfile=acpidump.log
    Load ACPI tables from output generated from acpidump or from sudo fwts --dump. The latter is preferred as fwts --dump is able to dump more tables than acpidump. This allows one to dump tables from one machine and processes them with fwts on another machine.

--uefi-get-var-multiple
    Specifies the number of times to get a variable in the uefirtvariable get variable stress test.

--uefi-set-var-multiple
    Specifies the number of times to set a variable in the uefirtvariable set variable stress test.

--uefi-query-var-multiple
    Specifies the number of times to query a variable in the uefirtvariable query variable stress test.

--filter-error-discard
    Specifies the errors that one wants to silently ignore. One supplies a comma sperated list of fwts error message labels that one wants fwts to not report as errors. fwts will run the test but if there is a test failure and the label matches the one supplied in this list fwts will then just ignore this error. This cannot be used with --filter-error-keep.

--filter-error-keep
    Specifies the errors that one wants to keep, all other errors are silently ignored. One supplies a comma sperated list of fwts error message labels that one wants fwts report as errors, other test failures will be not reported and silently ignored. This cannot be used with --filter-error-discard.

-f, --force-clean
    creates a new results log file, rather than just appending to any existing one (default).

-h, --help
    outputs the internal help page.

-i, --interactive
    run the interactive tests. These tests require user interaction.

--interactive-experimental
    run only interactive experimental tests.

-j, --json-data-path
    specifies the path to the fwts json data files. These files contain json formatted configuation tables, for example klog scanning patterns.

-k, --klog=file
    read the kernel log from the specified file rather than from the kernel log ring buffer. This allows one to run the kernel log scanning tests such as klog against pre-gathered log data.

--log-fields
    show the available log filtering fields. Specifying these fields with --log-filter to select which fields one wants to log.

--log-filter
    specify which particular types of log data to be output into the log file. Each line of log data is tagged with a special marker depending on what type of log information is being output. The available types can be see by using --log-fields. Specify the desired log types with comma separated list. To disable a field, prefix the name with ~, for example:
    --log-filter=RES,SUM logs just the results and summary lines.
    --log-filter=ALL,~INF logs all lines except for the information lines.

--log-format
    specify the information in each log line. The following specifiers are available:
    %date - date
    %time - time
    %field - log-filter fields
    %owner - name of the test routine
    %level - test failure level
    %line - log line
    e.g. --log-format="%date %time [%field] (%owner): "

--log-type
    specify the log type. Currently plaintext, json and xml log types are available and the default is plaintext.

--lspci=path
    specify the full path and filename to the the lspci binary.

-P, --power-states
    run S3 and S4 power state tests (s3, s4 tests)

--results-no-separators
    no pretty printing of horizontal separators in the results log file.

-r, --results-output=filename
    specify the results output log file. One can also specify stdout and stderr to redirect to these output streams.

-R, --rsdp=physaddr
    specify the physical address of ACPI RSDP. This is useful on some systems where it cannot be automatically detected.

--s3-delay-delta=N
    time to be added onto delay between each S3 iteration.

--s3-device-check
    check differences between device configurations over a S3 cycle. Note this adds 15 seconds delay after each s3 resume to allow wifi to re-associate.

--s3-device-check-delay
    specify the time to wait while devices re-configure (e.g. wifi to re-associate, ethernet to connect..) before a device configuration check is run. The default is 15 seconds. If this option is used the device checking is assumed so one does not also need to use the --s3-device-check flag.

--s3-hybrid
    Enables fwts to run Hybrid Sleep.

--s3-min-delay=N
    minimum time between S3 iterations.

--s3-max-delay=N
    maximum time between S3 iterations.

--s3-multiple=N
    specified the number of multiple S3 suspend/resume tests to run. The default is 2 tests.

--s3-quirks=--quirk[,--quirk]
    specify a comma separated list of quirk arguments to pass to pm-suspend, for example: --s3-quirks=--quirk-s3-bios,--quirk-save-pci

--s3-sleep-delay=N
    sleep N seconds from the start of the suspend to the wakeup time. Note that this time MUST be longer than the time it takes to suspend the machine otherwise the wakeup timer will fire during the suspend state. The default is 30 seconds.

--s3-suspend-time=N
    specify the maximum allowed suspend time in seconds. If suspend takes longer than this then an error is logged.

--s3-resume-time=N
    specify the maximum allowed resume time in seconds. If resume takes longer than this then an error is logged.

--s4-delay-delta=N
    time to be added onto delay between each S4 iteration.

--s4-device-check
    check differences between device configurations over a S4 cycle. Note this adds 15 seconds delay after each s3 resume to allow wifi to re-associate.

--s4-device-check-delay
    specify the time to wait while devices re-configure (e.g. wifi to re-associate, ethernet to connect..) before a device configuration check is run. The default is 15 seconds. If this option is used the device checking is assumed so one does not also need to use the --s4-device-check flag.

--s4-min-delay=N
    minimum time between S4 iterations.

--s4-max-delay=N
    maximum time between S4 iterations.

--s4-multiple=N
    specified the number of multiple S4 hibernate/resume tests to run. The default is 2 tests.

--s4-quirks=--quirk[,--quirk]
    specify a comma separated list of quirk arguments to pass to pm-hibernate, for example: --s4-quirks=--quirk-save-pci

--s4-sleep-delay=N
    sleep N seconds from the start of the hibernate to the wakeup time. Note that this time MUST be longer than the time it takes to hibernate the machine otherwise the wakeup timer will fire during the hibernate state. The default is currently 90 seconds.

-p, --show-progress
    show the progress of the tests being run. Each test will identified as it is being run. For long tests, a percentage of completion time will be displayed. As of fwts 0.19.06 this is enabled by default and can be disabled with --quiet (or -q).

-q, --quiet
    run quietly with no output to stdout.

-D, --show-progress-dialog
    output the progress of tests being run in a form that can be piped into the dialog tool with the --gauge option.

-s, --show-tests
    show the names of available tests. By default will show all tests. Use the --batch, --interactive, --batch-experimental, --interactive-experimental, --utils options to show these specific tests.

--show-tests-full
    show all the available tests listed by minor test description. By default will show all tests. Use the --batch, --interactive, --batch-experimental, --interactive-experimental options to show these specific tests.

--skip-test=test[,test..]
    specify tests to skip over and not run. List must be comma separated.

--stdout-summary
    output SUCCESS or FAILED to stdout at end of tests.

-t, --table-path=path
    specify the path containing ACPI tables. These tables need to be named in the format: tablename.dat, for example DSDT.dat, for example, as extracted using acpidump or fwts --dump and then acpixtract.

-u, --utils
    run utilities. Designed to dump system information, such as annotated ACPI tables, CMOS memory, Int 15 E820 memory map, firmware ROM data.

-v, --version
    output version number and build date of the fwts tool.

-w, --width=N
    specify the width in characters of the output logfile. The default is 130.

EXAMPLES

Run all the batch tests and append the results into the default log results.log:
    sudo fwts

Run all the interactive tests and start a clean results log called interactive.log:
    sudo fwts -i -f -r interactive.log

Run all the tests, interactive and batch:
    sudo fwts -i -b

Run just the battery and cpufreq tests:
    sudo fwts battery cpufreq

    sudo fwts --log-format="%date %line: "

Run all the interative tests and log just the results, info and summary data:
    sudo fwts -i --log-filter=RES,INF,SUM

Dump all the interesting firmware information into log files for analysis later:
    sudo fwts --dump

View kernel and ACPI driver version and BIOS information:
    sudo fwts -w 80 -r stdout version bios_info --log-filter=INF --log-format=""
