Read-Only File -+ System). Squashfs is a highly compressed read-only filesystem for Linux. -+ It uses zlib compression to compress both files, inodes and directories. -+ Inodes in the system are very small and all blocks are packed to minimise -+ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K. -+ SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full -+ uid/gid information, hard links and timestamps. -+ -+ Squashfs is intended for general read-only filesystem use, for archival -+ use (i.e. in cases where a .tar.gz file may be used), and in embedded -+ systems where low overhead is needed. Further information and filesystem tools -+ are available from http://squashfs.sourceforge.net. -+ -+ If you want to compile this as a module ( = code which can be -+ inserted in and removed from the running kernel whenever you want), -+ say M here and read <file:Documentation/modules.txt>.

This is done by redirecting modifying operations -+to a writeable location called "storage directory", and leaving the -+original data in the "base directory" untouched. When reading, the -+file system merges the modifed and original data so that only the -+newest versions will appear. This occurs transparently to the user, -+who can access the data like on any other read-write file system. -+ -+Base and storage directories may be located on the same or on -+different partitions and may be of different file system types. While -+the storage directory obviously needs to be writable, the base may or -+may not be writable, what doesn't matter as it will no be modified -+anyway. -+ -+ -+WHAT IS GOOD FOR? -+----------------- -+ -+The primary purpose of the mini_fo file system is to allow easy -+software updates to embedded systems, that often store their root -+file system in a read-only flash file system, but there are many -+more as for example sandboxing, or for allowing live-cds to -+permanently store information. -+ -+ -+BUILDING -+-------- -+This should be simple. Adjust the Makefile to point to the correct -+kernel headers you want to build the module for. Then: -+ -+ # make -+ -+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6 -+kernel. -+ -+If you are building the module for you current kernel, you can install -+the module (as root): -+ -+ # make install -+ -+or uninstall with -+ -+ # make uninstall -+ -+ -+USING THE FILE SYSTEM -+-------------------- -+ -+the general mount syntax is: -+ -+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\ -+ <base directory> <mount point> -+ -+Example: -+ -+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files -+on it: -+ -+load the module (as root) -+ -+ # insmod mini_fo.o for a 2.4 kernel or -+ -+ # insmod mini_fo.ko for a 2.6 kernel -+ -+ -+create a storage dir in tmp and a mountpoint for mini_fo: -+ -+ # mkdir /tmp/sto -+ # mkdir /mnt/mini_fo -+ -+and mount the mini_fo file system: -+ -+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo -+ -+ -+Now the data stored on the cd can be accessed via the mini_fo -+mountpoint just like any read-write file system, files can be modified -+and deleted, new ones can be created and so on. When done unmount the -+file system: -+ -+ # unmount /mnt/mini_fo -+ -+Note that if the file system is mounted again using the same storage -+file system, of course it will appear in the modified state again. If -+you remount it using an new empty storage directory, it will be -+unmodified. Therefore by executing: -+ -+ # cd /tmp/sto -+ # rm -rf * -+ -+you can nuke all the changes you made to the original file system. But -+ remember NEVER do this while the mini_fo file system is mounted! -+ -+ -+Alternatively you can use the mini_fo-overlay bash script, that -+simplifies managing mini_fo mounts. See TOOLS Section. -+ -+ -+TOOLS -+----- -+ -+mini_fo-merge (experimental): -+ -+This is a bash script that will merge changes contained in the storage -+directory back to the base directory. This allows mini_fo to function -+as a cache file system by overlaying a slow (network, ...) file system -+and using a fast (ramdisk, ...) as storage. When done, changes can be -+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge -+-h" for details. -+ -+It can be usefull for merging changes back after a successfull test -+(patches, software updates...) -+ -+ -+mini_fo-overlay: -+ -+This bash script simplifies managing one or more mini_fo mounts. For -+overlaying a directory called "basedir1", you can just call: -+ -+ # mini_fo-overlay basedir1 -+ -+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/" -+as storage to "/mnt/mini_fo-basedir1/". It has more options though, -+type "mini_fo-overlay -h" for details. -+ -+ -+DOCUMENTATION, REPORTING BUGS, GETTING HELP -+------------------------------------------- -+ -+Please visit the mini_fo project page at: -+ -+http://www.denx.de/twiki/bin/view/Know/MiniFOHome -+ -+ -+WARNINGS -+-------- -+ -+Never modify the base or the storage directorys while the mini_fo -+file system is mounted, or you might crash you system. Simply accessing -+and reading should not cause any trouble. -+ -+Exporting a mini_fo mount point via NFS has not been tested, and may -+or may not work. -+ -+Check the RELEASE_NOTES for details on bugs and features. -+ -+ -+ -+Copyright (C) 2004, 2005 Markus Klotzbuecher <mk@creamnet.de> -+ -+This program is free software; you can redistribute it and/or -+modify it under the terms of the GNU General Public License -+as published by the Free Software Foundation; either version -+2 of the License, or (at your option) any later version. -+ -+ ---- /dev/null -+++ b/fs/mini_fo/RELEASE_NOTES -@@ -0,0 +1,111 @@ -+Release: mini_fo-0.6.1 (v0-6-1) -+Date: 21.09.2005 -+ -+ -+Changes: -+-------- -+v0-6-1: -+ -+- bugfixes (see ChangeLog) -+ -+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see -+ README for details). -+ -+v0-6-0: -+ -+- Support for 2.4 and 2.6 (see Makefile) -+ -+- Partial hard link support (creating works as expected, but already -+ existing links in the base file system will be treated as if they -+ were individual files). -+ -+- Various bugfixes and cleanups. -+ -+ -+v0-6-0-pre1: -+ -+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of -+ many vital mini_fo parts such as the old whiteout list code which -+ has been replaced by the new META subsystem. -+ -+- Light weight directory renaming implemented. This means if a -+ directory is renamed via the mini_fo filesystem this will no longer -+ result in a complete copy in storage, instead only one empty -+ directory will be created. All base filed contained in the original -+ directory stay there until modified. -+ -+- Special files (creating, renaming, deleting etc.) now working. -+ -+- Many bugfixes and cleanup, mini_fo is now a lot more stable. -+ -+ -+v0-5-10: -+ -+- Final release of the 0-5-* versions. Next will be a complete rewrite -+ of many features. This release contains several bugfixes related to -+ directory renaming. -+ -+ -+v0-5-10-pre6: -+ -+- Lots of cleanup and several bugfixes related to directory deleting -+ -+- Directory renaming suddenly works, what is most likely due to the -+ fact tha that "mv" is smart: if the classic rename doesn't work it -+ will assume that source and target file are on different fs and will -+ copy the directory and try to remove the source directory. Until -+ directory removing wasn't implemented, it would fail to do this and -+ rollback. -+ So, directory renaming works for now, but it doesn't yet do what you -+ would expect from a overlay fs, so use with care. -+ -+ -+v0-5-10-pre5: -+ -+- implemented directory deleting -+- made parsing of mount options more stable -+- New format of mount options! (See README) -+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll -+ happily assume it never existed! -+ -+ -+Implemented features: -+--------------------- -+ -+- creating hard links (see BUGS on already existing hard links) -+- lightweight directory renaming -+- renaming device files, pipes, sockets, etc. -+- creating, renaming, deleting of special files -+- deleting directorys -+- general directory reading (simple "ls" ) -+- creating files in existing directorys -+- creating directorys -+- renaming files. -+- reading and writing files (involves opening) -+- appending to files (creates copy in storage) -+- deleting files -+- llseek works too, what allows editors to work -+- persistency (a deleted file stay deleted over remounts) -+- use of symbolic links -+- creating of device files -+ -+ -+Not (yet) implemented features: -+------------------------------- -+ -+- full hard link support. -+ -+ -+ -+BUGS: -+----- -+ -+Hard links in the base file system will be treated as individual -+files, not as links to one inode. -+ -+The main problem with hard links isn't allowing to create them, but -+their pure existence. If you modify a base hard link, the changes made -+will only show up on this link, the other link will remain in the -+original state. I hope to fix this someday. Please note that this does -+not effect the special hard links '.' and '..', that are handled -+seperately by the lower fs. ---- /dev/null -+++ b/fs/mini_fo/state.c -@@ -0,0 +1,620 @@ -+/* -+ * Copyright (C) 2005 Markus Klotzbuecher <mk@creamnet.de> -+ * -+ * This program is free software;

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, otherwise 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 follow: -+ -+ static struct pps_source_info_s 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 follow: -+ -+ 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 (is obvious that these parameters -+must be a subset of ones defined into 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, PPS_CAPTUREASSERT, ptr); -+ -+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 an 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 into 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 and after it is the -+sequence number. Other files are: -+ -+* echo: reports if the PPS source has an echo function or not; -+ -+* mode: reports available PPS functioning modes; -+ -+* name: reports the PPS source's name; -+ -+* path: reports the PPS source's device path, that is the device the -+ PPS source is connected to (if it exists). -+ -+ -+Testing the PPS support -+----------------------- -+ -+In order to test the PPS support even without specific hardware you can use -+the ktimer driver (see the client subsection in the PPS configuration menu) -+and the userland tools provided into Documentaion/pps/ directory. -+ -+Once you have enabled the compilation of ktimer just modprobe it (if -+not statically compiled): -+ -+ # modprobe ktimer -+ -+and the run ppstest as follow: -+ -+ $ ./ppstest /dev/pps0 -+ trying PPS source "/dev/pps1" -+ found PPS source "/dev/pps1" -+ ok, found 1 source(s), now start fetching data... -+ source 0 - assert 1186592699.388832443, sequence: 364 - clear 0.000000000, sequence: 0 -+ source 0 - assert 1186592700.388931295, sequence: 365 - clear 0.000000000, sequence: 0 -+ source 0 - assert 1186592701.389032765, sequence: 366 - clear 0.000000000, sequence: 0 -+ -+Please, note that to compile userland programs you need the file timepps.h -+(see Documentation/pps/). ---- /dev/null -+++ b/Documentation/pps/ppsctl.c -@@ -0,0 +1,62 @@ -+#include <stdio.h> -+#include <unistd.h> -+#include <stdlib.h> -+#include <errno.h> -+#include <sys/ioctl.h> -+#include <sys/types.h> -+#include <sys/stat.h> -+#include <fcntl.h> -+#include <string.h> -+#include <linux/serial.h> -+ -+void usage(char *name) -+{ -+ fprintf(stderr, "usage: %s <ttyS> [enable|disable]\n", name); -+ -+ exit(EXIT_FAILURE); -+} -+ -+int main(int argc, char *argv[]) -+{ -+ int fd; -+ int ret; -+ struct serial_struct ss; -+ -+ if (argc < 2) -+ usage(argv[0]); -+ -+ fd = open(argv[1], O_RDWR); -+ if (fd < 0) { -+ perror("open"); -+ exit(EXIT_FAILURE); -+ } -+ -+ ret = ioctl(fd, TIOCGSERIAL, &ss); -+ if (ret < 0) { -+ perror("ioctl(TIOCGSERIAL)"); -+ exit(EXIT_FAILURE); -+ } -+ -+ if (argc < 3) { /* just read PPS status */ -+ printf("PPS is %sabled\n", -+ ss.flags & ASYNC_HARDPPS_CD ?
