2017-10-26Unify storage threads into oneMichael Sevakis1-0/+6
* Editing a bunch of drivers' thread routines in order to implement a new feature is tedious. * No matter the number of storage drivers, they share one thread. No extra threads needed for CONFIG_STORAGE_MULTI. * Each has an event callback called by the storage thread. * A default callback is provided to fake sleeping in order to trigger idle callbacks. It could also do other default processing. Changes to it will be part of driver code without editing each one. * Drivers may sleep and wake as they please as long as they give a low pulse on their storage bit to ask to go into sleep mode. Idle callback is called on its behalf and driver immediately put into sleep mode. * Drivers may indicate they are to continue receiving events in USB mode, otherwise they receve nothing until disconnect (they do receive SYS_USB_DISCONNECTED no matter what). * Rework a few things to keep the callback implementation sane and maintainable. ata.c was dreadful with all those bools; make it a state machine and easier to follow. Remove last_user_activity; it has no purpose that isn't served by keeping the disk active through last_disk_activity instead. * Even-out stack sizes partly because of a lack of a decent place to define them by driver or SoC or whatever; it doesn't seem too critical to do that anyway. Many are simply too large while at least one isn't really adequate. They may be individually overridden if necessary (figure out where). The thread uses the greatest size demanded. Newer file code is much more frugal with stack space. I barely see use crack 50% after idle callbacks (usually mid-40s). Card insert/eject doesn't demand much. * No forcing of idle callbacks. If it isn't necessary for one or more non-disk storage types, it really isn't any more necessary for disk storage. Besides, it makes the whole thing easier to implement.

2017-03-12Do some housekeeping with fat.h and SECTOR_SIZEMichael Sevakis1-2/+1
Many includes of fat.h are pointless. Some includes are just for SECTOR_SIZE. Add a file 'firmware/include/fs_defines.h' for that and to define tuneable values that were scattered amongst various headers. Remove some local definitions of SECTOR_SIZE since they have to be in agreement with the rest of the fs code anyway. (We'll see what's in fact pointless in a moment ;) Change-Id: I9ba183bf58bd87f5c45eba7bd675c7e2c1c18ed5

2013-08-17Cleanup MV/MD macros a little.Michael Sevakis1-3/+3
When using variadic macros there's no need for IF_MD2/IF_MV2 to deal with function parameters. IF_MD/IF_MV are enough. Throw in IF_MD_DRV/ID_MV_VOL that return the parameter if MD/MV, or 0 if not. Change-Id: I7605e6039f3be19cb47110c84dcb3c5516f2c3eb
2011-08-30GSoC/Buflib: Add buflib memory alocator to the core.Thomas Martitz1-4/+11
The buflib memory allocator is handle based and can free and compact, move or resize memory on demand. This allows to effeciently allocate memory dynamically without an MMU, by avoiding fragmentation through memory compaction. This patch adds the buflib library to the core, along with convinience wrappers to omit the context parameter. Compaction is not yet enabled, but will be in a later patch. Therefore, this acts as a replacement for buffer_alloc/buffer_get_buffer() with the benifit of a debug menu. See buflib.h for some API documentation. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30380 a1c6a512-1295-4272-9138-f99709370657
