8602e8a8a9 SMP: irq_csection() has a bad assumption. It assumed that the state of certain variables. That was true on entry into the interrupt handler, but might change to the execution of logic within the interrupt handler. 2016-11-18 07:38:16 -06:00

f92afbfbf3 apps/examples/timer: Restore the timer example, but adapt the interface to use the new signal logic from Sebastien, Lorquet. Totally untested and probably does not work! 2016-11-17 15:19:17 -06:00

19c1c9d78b All timer lower half drivers. Port Sebastien's changes to all all other implementations of the timer lower half. Very many just and untested. Expect some problems. 2016-11-17 15:03:31 -06:00

d4a048c0c6 Timer driver: Add hooks to support signal notification of timer expiration. Commented out because invasive interface changes would also be required to complete the implementation. 2016-11-17 12:41:11 -06:00

ecb2d4cbc1 drivers/timer: Remove the TIOC_SETHANDLER IOCTL call. This calls directly from the timer driver into application code. That is non-standard, non-portable, and cannot be supported 2016-11-17 11:52:42 -06:00

bf096873a1 SAMV7 USBDEVHS: A problem occurred if the USB cable is unplugged while a large amount of data is send over an IN endpoint using DMA. If the USB cable is plugged in again after a few seconds it is not possible to send data over this IN endpoint again, all other endpoints work as expected. 
The problem occurs because if the USB cable is unplugged while an DMA transfer is in flight the transfer is canceled but the register SAM_USBHS_DEVDMACTRL is left in an undefined state.  The problem was fixed the problem by resetting the register SAM_USBHS_DEVDMACTRL to a known state. Additionally all pending interrupts are cleared.
