- 1. For IPECamera, shall we limit DMA packet size to xdma_packet_lenght register
- additionally to size of memory page?
-
 High Priority (we would need it for IPE Camera)
 =============
  1. Serialize access to the registers across applications
  2. Protect kmem_entries in the driver using spinlock
- 3. Extend Event API with function to generate triggers 
-    at the specified pace. By default the current cli 
-    implementation should be used. However, the hardware
-    alternative should be possible to implement.

+ 3. Implement pcilib_configure_autotrigger
