Jaska Uimonen 88c2ba2a84 topology: unify byt media pipeline params with apl media pipe 
Byt media pipeline has different parameters in topology for scheduling
deadline and frame count than apl. This produces funny 4-8x speed
playback. So unify with apl media pipe.

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"
-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			Take a snapshot of state

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
