Sound Open Firmware Tools
This is a collection of open source tools used to develop, test and debug SOF.
Building and Installing
mkdir build_tools
cd build_tools
cmake ..
make
make install
sof-logger
sof-logger is used to print logs delivered from FW dma_trace mechanism, by searching log entries in *.ldc file generated by rimage.
Every entry declared in FW is placed in elf output file (e.g. sof-apl) in .static_log_entries section in a form of struct defined in sof/src/include/sof/trace.h in sof fw repo.
*.ldc file contains snd_sof_logs_header (defined in
rmbox/logger_convert.c) following by .static_log_entries section
incorporated from FW elf file (e.g. sof-apl). snd_sof_logs_header
contains basic information about .static_log_entries section
like base_address and data_length.
sof-logger works by reading entry parameters value and entries addresses from FW dma_trace mechanism and searching suitable entry in *.ldc file by its address.
Usage sof-logger <option(s)> <file(s)>
Display mailbox contents
-h help
-l *.ldc_file Specify the *.ldc file
-i in_file Get traces from in_file, instead of the default
"/sys/kernel/debug/sof/etrace"
-o out_file Specify the output file, instead of default stdout
-t Get traces from "/sys/kernel/debug/sof/trace", instead
of the default "/sys/kernel/debug/sof/etrace"
-u baud Input data from a UART
-r Less formatted output for chained log processors
-p Get traces from stdin, instead of the default
"/sys/kernel/debug/sof/etrace"
-c Set timestamp clock in MHz
-e Enable checking firmware version with default verification file
"/sys/kernel/debug/sof/fw_version"
-v ver_file Enable checking firmware version with ver_file file,
instead of default: "/sys/kernel/debug/sof/fw_version"
-s state_name Take a snapshot of state. Save the debugfs entries in
state_name.*.txt.
Examples:
Get traces from "/sys/kernel/debug/sof/etrace" file, verifies fw_version with "/sys/kernel/debug/sof/fw_version" and prints logs to stdout
$ sof-logger -l ldc_file -e
Get traces from "/sys/kernel/debug/sof/etrace" file, verifies fw_version with
ver_file file and prints logs to stdout
$ sof-logger -l ldc_file -v ver_file
Get traces from "/sys/kernel/debug/sof/etrace" file and prints logs to stdout
$ sof-logger -l ldc_file
Get traces from "/sys/kernel/debug/sof/etrace" file and prints logs to
out_file file
$ sof-logger -l ldc_file -o out_file
Get traces from "/sys/kernel/debug/sof/trace" file and prints logs to stdout
$ sof-logger -l ldc_file -t
Get traces from "/sys/kernel/debug/sof/trace" file and prints logs to
out_file file
$ sof-logger -l ldc_file -t -o out_file
Get traces from stdin and prints logs to stdout
$ sof-logger -l ldc_file -p
Get traces from stdin and prints logs to out_file file
$ sof-logger -l ldc_file -p -o out_file
Get traces from trace_dump file and prints logs to stdout
$ sof-logger -l ldc_file -i trace_dump
Get traces from trace_dump file and prints logs to out_file file
$ sof-logger -l ldc_file -i trace_dump -o out_file
c flag is intended for defining clock value (in MHz) used to format log
timestamps. By default clock value is set to 19.2 (MHz). Below example
set clock value to 19.9 (MHz).
$ sof-logger -l ldc_file -i trace_dump -o out_file -c 19.9
sof-coredump-reader
Tool for processing FW stack dumps. In verbose mode it prints the stack leading to the core dump including DSP registers and function calls. It outputs unwrapped gdb command function call addresses to human readable function call format either to a file or stdout.
Usage sof-coredump-reader.py [-h] [-a ARCH] [-c] [-l COLUMNCOUNT] [-v]
(--stdout | -o OUTFILE) [--stdin | -i INFILE]
-h show this help message and exit
-a ARCH determine architecture of dump file; valid archs are: LE64bit, LE32bit
-c set output to be colourful
-l COLUMNCOUNT set how many colums to group the output in
-v increase output verbosity
--stdin input is from stdin
-i INFILE path to sys dump bin
--stdout output is to stdout
-o OUTFILE output is to FILE
sof-coredump-to-gdb.sh shows example usage of sof-coredump-reader.py We read from dump file into sof-coredump-reader.py, then we pipe its output to xt-gdb, which operates on given elf-file.
$ ./sof-coredump-to-gdb.sh sof-apl dump_file
tests
To generate all test configuration files:
make tests
testbench
The host testbench is meant to serve as a vehicle to test components for functionality and quality of processed samples.
Compilation steps
Run the host-build-all.sh to build the required libraries for the testbench. It should also build the testbench executable.
Running the Testbench
The test can be invoked by running the "testbench" bin in the src/host directory.
Compile and run using script provided (Recommended):
Set up the input arguments for the test in host-testbench.sh and invoke it to compile the host libraries and execute the testbench.
Known Limitations:
-
Currently, testbench code supports simple volume topologies only.
-
When setting up arguments, please keep the same file format for input and output files
