Introduction +=============== + +gcov profiling kernel support enables the use of GCC's coverage testing +tool gcov [1] with the Linux kernel. Coverage data of a running kernel +is exported in gcov-compatible format via the "gcov" debugfs directory. +To get coverage data for a specific file, change to the kernel build +directory and use gcov with the -o option as follows (requires root): + +# cd /tmp/linux-out +# gcov -o /sys/kernel/debug/gcov/tmp/linux-out/kernel spinlock.c + +This will create source code files annotated with execution counts +in the current directory.

Also CONFIG_GCOV_PROFILE_ALL may not be supported +on all architectures. + +Profiling data will only become accessible once debugfs has been +mounted: + + mount -t debugfs none /sys/kernel/debug + + +3. Customization +================ + +To enable profiling for specific files or directories, add a line +similar to the following to the respective kernel Makefile: + + For a single file (e.g. main.o): + GCOV_PROFILE_main.o := y + + For all files in one directory: + GCOV_PROFILE := y + +To exclude files from being profiled even when CONFIG_GCOV_PROFILE_ALL +is specified, use: + + GCOV_PROFILE_main.o := n + and: + GCOV_PROFILE := n + +Only files which are linked to the main kernel image or are compiled as +kernel modules are supported by this mechanism. + + +4. Files +======== + +The gcov kernel support creates the following files in debugfs: + + /sys/kernel/debug/gcov + Parent directory for all gcov-related files. + + /sys/kernel/debug/gcov/reset + Global reset file: resets all coverage data to zero when + written to. + + /sys/kernel/debug/gcov/path/to/compile/dir/file.gcda + The actual gcov data file as understood by the gcov + tool.

This file is generated by gcc when compiling with + option -ftest-coverage. + + +5. Modules +========== + +Kernel modules may contain cleanup code which is only run during +module unload time. The gcov mechanism provides a means to collect +coverage data for such code by keeping a copy of the data associated +with the unloaded module. This data remains available through debugfs. +Once the module is loaded again, the associated coverage counters are +initialized with the data from its previous instantiation. + +This behavior can be deactivated by specifying the gcov_persist kernel +parameter: + + gcov_persist=0 + +At run-time, a user can also choose to discard data for an unloaded +module by writing to its data file or the global reset file. + + +6. Separated build and test machines +==================================== + +The gcov kernel profiling infrastructure is designed to work out-of-the +box for setups where kernels are built and run on the same machine. In +cases where the kernel runs on a separate machine, special preparations +must be made, depending on where the gcov tool is used: + +a) gcov is run on the TEST machine + +The gcov tool version on the test machine must be compatible with the +gcc version used for kernel build.

This assumption is +ok for the serial and parallel port, where you can do something +useful besides(!) the gathering of timestamps as it is the central +task for a PPS-API. But this assumption does not work for a single +purpose GPIO line. In this case even basic file-related functionality +(like read() and write()) makes no sense at all and should not be a +precondition for the use of a PPS-API. + +The problem can be simply solved if you consider that a PPS source is +not always connected with a GPS data source. + +So your programs should check if the GPS data source (the serial port +for instance) is a PPS source too, and if not they should provide the +possibility to open another device as PPS source. + +In LinuxPPS the PPS sources are simply char devices usually mapped +into files /dev/pps0, /dev/pps1, etc.. + + +Coding example +-------------- + +To register a PPS source into the kernel you should define a struct +pps_source_info_s as follows: + + static struct pps_source_info pps_ktimer_info = { + .name = "ktimer", + .path = "", + .mode = PPS_CAPTUREASSERT | PPS_OFFSETASSERT | \ + PPS_ECHOASSERT | \ + PPS_CANWAIT | PPS_TSFMT_TSPEC, + .echo = pps_ktimer_echo, + .owner = THIS_MODULE, + }; + +and then calling the function pps_register_source() in your +intialization routine as follows: + + source = pps_register_source(&pps_ktimer_info, + PPS_CAPTUREASSERT | PPS_OFFSETASSERT); + +The pps_register_source() prototype is: + + int pps_register_source(struct pps_source_info_s *info, int default_params) + +where "info" is a pointer to a structure that describes a particular +PPS source, "default_params" tells the system what the initial default +parameters for the device should be (it is obvious that these parameters +must be a subset of ones defined in the struct +pps_source_info_s which describe the capabilities of the driver). + +Once you have registered a new PPS source into the system you can +signal an assert event (for example in the interrupt handler routine) +just using: + + pps_event(source, &ts, PPS_CAPTUREASSERT, ptr) + +where "ts" is the event's timestamp. + +The same function may also run the defined echo function +(pps_ktimer_echo(), passing to it the "ptr" pointer) if the user +asked for that... etc.. + +Please see the file drivers/pps/clients/ktimer.c for example code. + + +SYSFS support +------------- + +If the SYSFS filesystem is enabled in the kernel it provides a new class: + + $ ls /sys/class/pps/ + pps0/ pps1/ pps2/ + +Every directory is the ID of a PPS sources defined in the system and +inside you find several files: + + $ ls /sys/class/pps/pps0/ + assert clear echo mode name path subsystem@ uevent + +Inside each "assert" and "clear" file you can find the timestamp and a +sequence number: + + $ cat /sys/class/pps/pps0/assert + 1170026870.983207967#8 + +Where before the "#" is the timestamp in seconds; after it is the +sequence number.

Actually, you can read in the core file and look at - the contents of the user struct to find out what the floating point - registers contain. - The actual file contents are as follows: - UPAGE: 1 page consisting of a user struct that tells gdb what is present - in the file. Directly after this is a copy of the task_struct, which - is currently not used by gdb, but it may come in useful at some point. - All of the registers are stored as part of the upage. The upage should - always be only one page. - DATA: The data area is stored. We use current->end_text to - current->brk to pick up all of the user variables, plus any memory - that may have been malloced. No attempt is made to determine if a page - is demand-zero or if a page is totally unused, we just cover the entire - range. All of the addresses are rounded in such a way that an integral - number of pages is written. - STACK: We need the stack information in order to get a meaningful - backtrace. We need to write the data from (esp) to - current->start_stack, so we round each of these off in order to be able - to write an integer number of pages. - The minimum core file size is 3 pages, or 12288 bytes. -*/ -struct user_bfinfp_struct { -};
