Thomas Martitz 22e802e800 playback,talk: Share audiobuffer via core_alloc_maximum().
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.

usb_charging_only.c usb PACK_DATA: use a static inline to enable type checking 2011-12-29 21:58:34 +00:00
usb_charging_only.h USB retweaking: Take out the USB_REQUEST/RELEASE_DISK scheme and simply ask the USB core whether or not any drivers require exclusive access at the moment of connect. Doing anthing else just produces nasty effects on Windows because it expects some communication just for enabling the PHY and not allowing it to mount volumes if a thread doesn't ack causes annoying error message boxes. Make behavior of each USB type identical from the system perspective. Some miscellaneous changes (simplify, ata->storage naming, define only used USB_* enums values were possible). 2009-01-13 16:27:35 +00:00

usb_storage.h Allow class drivers to reuse the core data buffer for control transfers. This doesn't make much difference right now, but it should keep HID memory usage lower (once HID is ready) (FS#10146 by Tomer Shalev) 2009-04-18 20:40:50 +00:00
