2017-10-26Unify storage threads into oneMichael Sevakis1-1/+1
* 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.

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

2009-07-17Revert r21912 : "Storage API : remove undeeded target-specific functions"Rafaël Carré1-0/+3
After a discussion mixed on mailing list and irc, it was agreed that more abstraction for plugins is better (so developers don't have to add a check to HAVE_DISK_STORAGE when writing disk-specific code) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21923 a1c6a512-1295-4272-9138-f99709370657

2009-07-01add firmware/driver/sd.c which contains common code between SD driversRafaël Carré1-5/+2
ingenic SD driver needs more cleanup so it still doesn't use the common code correct a comment in hotswap.c: card_extract_bits assume most significant word of register first (so, use this order) fix debug menu which used MMC specific commands / bits positions in csd/cid move the default block size of 512 into sd.h move the mantissa & exponent table into a single file (sd.c) to reduce binsize. we don't need to export it anymore anyway TODO : ingenic cleanup (will happen soon so building sd.c is not conditional) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21601 a1c6a512-1295-4272-9138-f99709370657
2009-07-01Merge tCardInfo struct (MMC) and tSDCardInfo struct (SD)Rafaël Carré1-0/+8
Put specific members under #ifdef (CONFIG_STORAGE & STORAGE_xx) (2 members for SD and 1 for MMC) Fix a typo: tsac doesn't exist and must be read taac Move card_get_info functions declaration inside hotswap.h to remove mutual inclusion of ata_mmc.h and hotswap.h Move static const data structures from SD drivers into sd.h (sd_exponent and sd_mantissa) Fix sd_command prototypes in SD drivers (card registers are unsigned long) Fix speed calculation in Sansa AMS driver (PP SD driver needs to be checked) Move ata-sd-target.h to sd-pp-target.h to reflect the PP specifity. Now it only contains declaration of microsd_int() Remove unused ata-sd-target.h for injenic TODO: - check if CSD register bits are extracted correctly in PP driver - correctly define read_timeout and write_timeout unit for MMC & SD, and use timeouts in Sansa AMS driver git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21586 a1c6a512-1295-4272-9138-f99709370657
