Angus Gratton	6e4b0c3e2f	freertos: Remove either one or two assertions from "fast path" of vPortCPUReleaseMutex() ... Saves a few cycles by only testing the count validity once, and never for the common case where the mutex was not recursively locked.	2018-07-31 06:35:25 +00:00
Jeroen Domburg	70ab924dbb	Especially when internal memory fills up, some FreeRTOS structures (queues etc) get allocated in psram. These structures also contain a spinlock, which needs an atomic-compare-swap operation to work. The psram hardware, however, does not support this operation. As a workaround, this patch detects these spinlocks and will, instead of S32C1I, use equivalent C-code to simulate the behaviour, with an (internal) mux for atomicity.	2018-02-02 17:11:06 +08:00
