2020-08-20Allow mounting of any directory as the root directory.William Wilgus5-12/+121
Provide definitions for the macros: * RB_ROOT_VOL_HIDDEN(v) to exclude certain items from the root. * RB_ROOT_CONTENTS to return a string with the name of the directory to mount in the root. Defaults are in export/rbpaths.h It's a bit much for those that don't need the full functionality. Some conditional define can cut it back a lot to cut out things only needed if alternate root mounts are required. I'm just not bothering yet. The basic concept would be applied to all targets to keep file code from forking too much. Change-Id: I90b5c0a1c949283d3102c16734b0b6ac73901a30

2019-07-19Add proper float formatting to vuprintfMichael Sevakis1-0/+59
Wanted to see how gnarly it is to do. Big number handling could be done with better algorithms since it can get a bit slow with large integers or tiny fractions with many lead zeros when only a few digits are needed. Anyway, it supports %e, %E, %f, %F, %g and %G. No %a or long double support seems warranted at the moment. Assumes IEEE 754 double format but it's laid out to be able to replace a function to handle others if needed. Tested in a driver program that has a duplicate vuprintf and the content was pasted in once it looked sound enough to put up a patch. Change-Id: I6dae8624d3208e644c88e36e6a17d8fc9144f988

New support as well as some buggy support fixed. Still no floating point support if ever that would be desired. Support (*): * Flags: '-', '+', ' ', '#', '0' * Width and precision: 'n', '.n', '*' and '.*' * Length modifiers: 'hh', 'h', 'j', 'l', 'll', 't', 'z' * Radix: 'c', 'd', 'i', 'n', 'o', 'p/P', 's', 'u', 'x/X' (*) Provision exists to switch lesser-used stuff on or off or when certain functionality isn't desired (bootloader?). The compulsory radixes are everything but 'o', 'n', 'p/P' and 'x/X' with length modifiers being optional. The default setup is 'l', 'z', 'c', 'd', 'p/P', 's', 'u', 'x/X'. * Move fdprintf() to its own file. It was in a strange place. * Make callers compatible and fix a couple snprintf() bugs while at it.

2017-10-29Add boot from other volumes in bootloader on targets with HAVE_MULTIVOLUMEWilliam Wilgus1-0/+17
Adds the ability to load firmware from other drives on MULTIVOLUME targets Mihail Zenkov <> had posted a hard coded patch to allow this on several Sansa players, I made it more universal Redirect file rockbox_main.<name> should placed in root of drive you would like to be main, if this file empty or there a single slash '/' firmware will be loaded from /.rockbox in root of this drive If instead a /<*DIRECTORY*> is supplied in rockbox_main.<name> then firmware will be loaded from /<dir>/.rockbox/ NOTES* The directory can have multiple levels however.. leading slash MUST be included trailing slash can be omitted (eg. /test/.rockbox would be simply '/test' in the redirect file) Redirect file will not work on internal drive (whatever is default boot drive) Volume with the highest index containing redirect file will be loaded first. Firmware file is checked for boot data region, if missing, firmware image will not be loaded. On failure or if no redirect file is found load will fallback to internal drive Currently only Sansa Fuze+, Sansa Clip+, Sansa Clip Zip, Sansa Fuzev2, and Sansa Fuzev1 are implemented. Players (with HAVE_MULTIVOLUME) will need #define HAVE_BOOTDATA and #define BOOT_REDIR "rockbox_main.<name>" added to their config file boot_data is implemented in crt0.s file (See g#1552) ARM and IMX233 have aleady been implemented Once these conditions are met <HAVE_MULTIBOOT> will be defined by config.h Partitions on the drives are able to have a redirect as well.

2017-03-12Dircache: Refine name allocation and error handling.Michael Sevakis1-1/+1

2017-01-17Do some debug and preparatory work for ramcache and playlistMichael Sevakis4-51/+104
The file system rework introduced incompatibility between dircache and the tagcache ramcache and playlist dircache path caching. This update makes changes to filesystem code to reintegrate all that. It also fixes a couple bugs that were found when vetting all the code. The filestream cache was being reset without regard to the stream even if it was shared in write mode (made work of .playlist_control). Better handling of unmounting gives files a better go at force-closing them without risk to disk integrity. Did some miscellaneous pedantic changes. Improved efficiency of testing a file's existence (a little) since the path parser will be shared between file code and parsing for the sake of finding dircache references, not duplicated as before. This commit doesn't reenable said items just for the sake of keeping changes separate and related. Plan for the next is to enable dircache again for the playlists (easy peasy) and reenable tagcache ramcache but *without* the dircache path caching because it's rather substantial to change in itself. The ramcache will still function without dircache. Change-Id: I7e2a9910b866251fa8333e1275f72fcfc8425d2d

2015-01-02Improve core_alloc() / buflib_alloc() documentationThomas Jarosch1-3/+10
Document the fact that buffers are movable by default. Care must be taken to not pass them to functions that yield(). Also clarify other things: - Passing NULL as "ops" to buflib_alloc_ex() causes buffers to be movable by default (but not shrinkable). - If you want shrinkable buffers during compaction, you have to provide a shrink callback. - To disable buffer movement, you have to pass NULL for the move_callback inside the callback structure. - The concept of default callbacks was removed long ago, remove the only reference of it.

2014-08-29Add mempcpy implementationMichael Sevakis1-2/+10
A GNU extension that returns dst + size instead of dst. It's a nice shortcut when copying strings with a known size or back-to-back blocks and you have to do it often. May of course be called directly or alternately through __builtin_mempcpy in some compiler versions. For ASM on native targets, it is implemented as an alternate entrypoint to memcpy which adds minimal code and overhead. Change-Id: I4cbb3483f6df3c1007247fe0a95fd7078737462b
2014-08-30Rewrite filesystem code (WIP)Michael Sevakis12-272/+1133
This patch redoes the filesystem code from the FAT driver up to the clipboard code in onplay.c. Not every aspect of this is finished therefore it is still "WIP". I don't wish to do too much at once (haha!). What is left to do is get dircache back in the sim and find an implementation for the dircache indicies in the tagcache and playlist code or do something else that has the same benefit. Leaving these out for now does not make anything unusable. All the basics are done. Phone app code should probably get vetted (and app path handling just plain rewritten as environment expansions); the SDL app and Android run well. Main things addressed: 1) Thread safety: There is none right now in the trunk code. Most of what currently works is luck when multiple threads are involved or multiple descriptors to the same file are open. 2) POSIX compliance: Many of the functions behave nothing like their counterparts on a host system. This leads to inconsistent code or very different behavior from native to hosted. One huge offender was rename(). Going point by point would fill a book. 3) Actual running RAM usage: Many targets will use less RAM and less stack space (some more RAM because I upped the number of cache buffers for large memory). There's very little memory lying fallow in rarely-used areas (see 'Key core changes' below). Also, all targets may open the same number of directory streams whereas before those with less than 8MB RAM were limited to 8, not 12 implying those targets will save slightly less. 4) Performance: The test_disk plugin shows markedly improved performance, particularly in the area of (uncached) directory scanning, due partly to more optimal directory reading and to a better sector cache algorithm. Uncached times tend to be better while there is a bit of a slowdown in dircache due to it being a bit heavier of an implementation. It's not noticeable by a human as far as I can say. Key core changes: 1) Files and directories share core code and data structures. 2) The filesystem code knows which descriptors refer to same file. This ensures that changes from one stream are appropriately reflected in every open descriptor for that file (fileobj_mgr.c). 3) File and directory cache buffers are borrowed from the main sector cache. This means that when they are not in use by a file, they are not wasted, but used for the cache. Most of the time, only a few of them are needed. It also means that adding more file and directory handles is less expensive. All one must do in ensure a large enough cache to borrow from. 4) Relative path components are supported and the namespace is unified. It does not support full relative paths to an implied current directory; what is does support is use of "." and "..". Adding the former would not be very difficult. The namespace is unified in the sense that volumes may be specified several times along with relative parts, e.g.: "/<0>/foo/../../<1>/bar" :<=> "/<1>/bar". 5) Stack usage is down due to sharing of data, static allocation and less duplication of strings on the stack. This requires more serialization than I would like but since the number of threads is limited to a low number, the tradoff in favor of the stack seems reasonable. 6) Separates and heirarchicalizes (sic) the SIM and APP filesystem code. SIM path and volume handling is just like the target. Some aspects of the APP file code get more straightforward (e.g. no path hashing is needed). Dircache: Deserves its own section. Dircache is new but pays homage to the old. The old one was not compatible and so it, since it got redone, does all the stuff it always should have done such as: 1) It may be update and used at any time during the build process. No longer has one to wait for it to finish building to do basic file management (create, remove, rename, etc.). 2) It does not need to be either fully scanned or completely disabled; it can be incomplete (i.e. overfilled, missing paths), still be of benefit and be correct. 3) Handles mounting and dismounting of individual volumes which means a full rebuild is not needed just because you pop a new SD card in the slot. Now, because it reuses its freed entry data, may rebuild only that volume. 4) Much more fundamental to the file code. When it is built, it is the keeper of the master file list whether enabled or not ("disabled" is just a state of the cache). Its must always to ready to be started and bind all streams opened prior to being enabled. 5) Maintains any short filenames in OEM format which means that it does not need to be rebuilt when changing the default codepage. Miscellaneous Compatibility: 1) Update any other code that would otherwise not work such as the hotswap mounting code in various card drivers. 2) File management: Clipboard needed updating because of the behavioral changes. Still needs a little more work on some finer points. 3) Remove now-obsolete functionality such as the mutex's "no preempt" flag (which was only for the prior FAT driver). 4) struct dirinfo uses time_t rather than raw FAT directory entry time fields. I plan to follow up on genericizing everything there (i.e. no FAT attributes). 5) unicode.c needed some redoing so that the file code does not try try to load codepages during a scan, which is actually a problem with the current code. The default codepage, if any is required, is now kept in RAM separarately (bufalloced) from codepages specified to iso_decode() (which must not be bufalloced because the conversion may be done by playback threads). Brings with it some additional reusable core code: 1) Revised file functions: Reusable code that does things such as safe path concatenation and parsing without buffer limitations or data duplication. Variants that copy or alter the input path may be based off these. To do: 1) Put dircache functionality back in the sim. Treating it internally as a different kind of file system seems the best approach at this time. 2) Restore use of dircache indexes in the playlist and database or something effectively the same. Since the cache doesn't have to be complete in order to be used, not getting a hit on the cache doesn't unambiguously say if the path exists or not.

This allows, hopefully optimized, macros from the host OS's headers to be used when building any hosted target obviating the need for NEED_GENERIC_BYTESWAPS unless the target simply doesn't define its own optimized versions (MIPS!).

2014-08-06Add multi-reader, single-writer locks to kernel.Michael Sevakis1-0/+231
Any number of readers may be in the critical section at a time and writers are mutually exclusive to all other threads. They are a better choice when data is rarely modified but often read and multiple threads can safely access it for reading. Priority inheritance is fully implemented along with other changes to the kernel to fully support it on multiowner objects. This also cleans up priority code in the kernel and updates some associated structures in existing objects to the cleaner form. Currently doesn't add the mrsw_lock.[ch] files since they're not yet needed by anything but the supporting improvements are still useful. This includes a typed bitarray API (bitarray.h) which is pretty basic for now.

2013-04-15Straighten out the mad twisted state of sound.c and related areas.Michael Sevakis1-0/+5
This is going right in since it's long overdue. If anything is goofed, drop me a line or just tweak it yourself if you know what's wrong. :-) Make HW/SW codec interface more uniform when emulating HW functionality on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to- DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX" APIs are all in sound.c with none in DSP code any longer. Reduce number of settings definitions needed by each codec by providing defaults for common ones like balance, channels and SW tone controls. Remove need for separate SIM code and tables and add virtual codec header for hosted targets. Change-Id: I3f23702bca054fc9bda40f49824ce681bb7f777b
2013-04-10Move fixedpoint.h to be accessible in /firmware.Michael Sevakis1-0/+111
Will need it soon enough. Combine the contents of all the various fixedpoint.h files. Not moving fixedpoint.c for now since I'm not sure where it should be and it causes some dependency issues. Change-Id: Ideacbca2ca78f9158c2b114b113c274f68e908d5
