2014-08-08Do some kernel cleanupMichael Sevakis
* Seal away private thread and kernel definitions and declarations into the internal headers in order to better hide internal structure. * Add a thread-common.c file that keeps shared functions together. List functions aren't messed with since that's about to be changed to different ones. * It is necessary to modify some ARM/PP stuff since GCC was complaining about constant pool distance and I would rather not force dump it. Just bl the cache calls in the startup and exit code and let it use veneers if it must. * Clean up redundant #includes in relevant areas and reorganize them. * Expunge useless and dangerous stuff like remove_thread().

2014-08-06Add multi-reader, single-writer locks to kernel.Michael Sevakis
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.

2012-01-04Reorganise USB initialisation to not depend on a specific enumeration ↵Frank Gevaerts

Users will have to reboot to OF manually or to power off, and then plug USB No message is displayed because usb_detect() is run from a tick This lacks documentation but should be OK for Unstable devices, and will hopefully prevent clueless users from opening their devices and breaking them definitely, instead of waiting for the battery to power off. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27837 a1c6a512-1295-4272-9138-f99709370657

2010-05-17as3514/as3543 fixesRafaël Carré
- Enable end of charge monitoring once, it doesn't need to be disabled - Acknowledge the first (wrong) end of charge interrupt on charger enable (this had been broken in r25299) - Centralize reads to ENRD* registers and cache the results when needed - on PP it is not needed because reads are atomic, we only check for end of charge when the charging, and for charger presence when discharging as3525v2 (using as3543) specifics - I got the datasheet today from AMS, thanks to them for being so fast and not require me to sign tons of papers! - USB detection now works on as3525v2 using the as3543. Clip+ won't reboot to OF yet, it needs mkamsboot support first (usbstack disabled) - Charging should work, the CHARGER register is at a different place, it is an extended PMU register -> use ascodec_read/write_charger() to access it - real interrupts are not used yet for ENRD, we get thousands of interrupts per second, apparently only limited by the i2c clock. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26116 a1c6a512-1295-4272-9138-f99709370657
