0c9abbfe67 STM32L4: Add IWDG peripheral. This is the same as for STM32 except that prescale and reload can be 
changed after watchdog has been started, as this seems to work on L4.

7ffbb704d6 This is based on a patch by Taras Drozdovsky. Basically, the delay that was added during the integration of the CDC/ACM host driver was interfering with streaming audio. That delay was put there to prevent build endpoints from hogging the system bandwidth. So what do we do? Do we hog the bandwidth or do we insert arbitrarity delays. I think both ideas such. 2017-05-21 14:28:29 -06:00

9169ff6a15 stm32_serial: fix freezing serial port. Serial interrupt enable/disable functions do not disable interrupts and can freeze device when serial interrupt is received while execution is at those functions. 
Trivially triggered with two or more threads write to regular syslog stream and to emergency stream. In this case, freeze happens because of mismatch of priv->ie (TXEIE == 0) and actually enabled interrupts in USART registers (TXEIE == 1), which leads to unhandled TXE interrupt
and causes interrupt storm for USART.

6a3800f611 There can be a failure in IOB allocation to some asynchronous behavior caused by the use of sem_post(). Consider this scenario: 
Task A holds an IOB.  There are no further IOBs.  The value of semcount is zero.
Task B calls iob_alloc().  Since there are not IOBs, it calls sem_wait().  The v
alue of semcount is now -1.

Task A frees the IOB.  iob_free() adds the IOB to the free list and calls sem_post() this makes Task B ready to run and sets semcount to zero NOT 1.  There is one IOB in the free list and semcount is zero.  When Task B wakes up it would increment the sem_count back to the correct value.

But an interrupt or another task runs occurs before Task B executes.  The interrupt or other tak takes the IOB off of the free list and decrements the semcount.  But since semcount is then < 0, this causes the assertion because that is an invalid state in the interrupt handler.

So I think that the root cause is that there the asynchrony between incrementing the semcount.  This change separates the list of IOBs:  Currently there is only a free list of IOBs.  The problem, I believe, is because of asynchronies due sem_post() post cause the semcount and the list content to become out of sync.  This change adds a new 'committed' list:  When there is a task waiting for an IOB, it will go into the committed list rather than the free list before the semaphore is posted.  On the waiting side, when awakened from the semaphore wait, it will expect to find its IOB in the committed list, rather than free list.

In this way, the content of the free list and the value of the semaphore count always remain in sync.
