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
Run all the batch tests and define a new log format using just the date and line number:
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=""
Show the batch and batch experimental tests:
fwts --show-tests --batch --batch-experimental
Run multiple S3 tests with delay between each test ranging from 1 second to 10 seconds
with a delay delta per test of 0.2 seconds
sudo fwts s3 --s3-multiple=100 --s3-min-delay=1 --s3-max-delay=10
--s3-delay-delta=0.2
