12 daysusb_storage: Fix a memset in SCSI_INQUIRY that overflowed its bufferSolomon Peachy1-1/+1
The funny thing is that the memset() for the field in question was redundant, as the overall inquiry structure was memset(0) already. Change-Id: I8bec0c93c9317823ff39cf7133535e3bf58fb987

2021-06-12USB Serial: Implement Abstract Control ManagementTomasz Moń1-15/+207
On devices that can assign interrupt IN, bulk IN and bulk OUT endpoints this change results in the serial interface working out of the box on Linux and Windows. On Linux it is registered as ttyACM device and on Windows it is assigned a COM port number. On devices that cannot assign the interrupt IN this change won't have any effect. Implement minimum required interface control requests. Respond with whatever line coding was set to make terminal programs happy. Change-Id: Id7d3899d8546e45d7cb4ecc3fe464908cb59e810

2018-07-30Workaround for usb_storage_init_connection() panicCástor Muñoz1-0/+1
For s5l8701, s5l8702 and as3525v2 targets. The crash occurs when USB is inserted or extracted while the playlist is being loaded or updated (it could take a few seconds for huge playlists), at this point all buflib memory is allocated and not freed before usb_starage_init_connection() is executed. This workaround mitigates this panic by using static memory for USB buffers, so this memory cannot be used for other tasks, in addition the problem still persist when playlist load is 'paused' by USB insertion and then updated after USB extraction.

Add a file 'firmware/include/fs_defines.h' for that and to define tuneable values that were scattered amongst various headers.

Based on g#844 and g#949, it is intended as a replacement for the current s3c6400x USB driver. The DesignWare USB OTG core is integrated into many SoC's, however HW core version and capabilities (mainly DMA mode, Tx FIFO mode, FIFO size and number of available IN/OUT endpoins) may differ: CPU targets HW ver DMA NPTX FIFO FIFO sz #IN/OUT -------- ------------- ------ --- --------- ------- ------- as3525v2 sansaclipplus 2.60a Yes Dedicated 0x535 4/4 sansaclipv2 sansaclipzip sansafuzev2 s5l8701 ipodnano2g 2.20a Yes Shared 0x500 4/5 s5l8702 ipod6g 2.60a Yes Dedicated 0x820 7/7 ipodnano3g s5l8720 ipodnano4g ? ? ? ? ? Functionality supported by this driver: - Device mode, compatible with USB 1.1/2.0 hosts. - Shared FIFO (USB_DW_SHARED_FIFO) or dedicated FIFOs. - No DMA (USB_DW_ARCH_SLAVE) or internal DMA mode. - Concurrent transfers: control, bulk (usb_storage, usb_serial) and interrupt (usb_hid). Actually this driver is not used by any CPU, it will be enabled for each individual CPU/target in next patches. Change-Id: I74a1e836d18927a31f6977d71115fb442477dd5f

2014-08-30Rewrite filesystem code (WIP)Michael Sevakis1-4/+1
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.

Windows will try to retrieve such a descriptor on first connect. If the device returns STALL or a regular string descriptor (i.e. not one that follows the Microsoft OS Descriptor spec), things will continue normally. Unfortunately some of our low-level USB drivers have issues with STALL so any other valid descriptor is the next best solution.

2013-12-23playback,talk: Share audiobuffer via core_alloc_maximum().Thomas Martitz1-5/+12
This fixes the radioart crash that was the result of buffering.c working on a freed buffer at the same time as buflib (radioart uses buffering.c for the images). With this change the buffer is owned by buflib exclusively so this cannot happen. As a result, audio_get_buffer() doesn't exist anymore. Callers should call core_alloc_maximum() directly. This buffer needs to be protected as usual against movement if necessary (previously it was not protected at all which cased the radioart crash), To get most of it they can adjust the willingness of the talk engine to give its buffer away (at the expense of disabling voice interface) with the new talk_buffer_set_policy() function.

2012-12-07usb: add support for hardware handled SET ADDR/CONFIGAmaury Pouly1-17/+53
Some USB controllers like the one of the Rockchip 27xx handle some requests in pure hardware. This is especially a problem for two of them: - SET ADDR which is used by our core to track the DEFAULT/ADDRESS state and is required for the drivers to work properly - SET CONFIG which is used by our core to initialise the drivers by calling init_connection() In these cases we need a way to notify the core that such requests happened. We do this by exporting two functions which directly notify the core about these requests and perform the necessary init steps required without doing the actual USB transfers. Special care is needed because these functions could be called from an interrupt handler. For this reason we still use the usb_queue and introduce new IDs so that they are processed in order and safely. No functional change is intended, both in the usbstack and on targets without such quirks. Change-Id: Ie42feffd4584e88bf37cff018b627f333dca1140
