We update sync to reflect that the firmware version is compatible with that option. We don't need to check both of them again further down the code. Signed-off-by:

All the memory operations featured in this file modify/access memory that is only accessed by the CPU. So we can assume that all the memory barrier handling done by the completion routines is good enough for us. Signed-off-by:

It is preferred in the kernel to avoid using semaphores to wait for events, as they are optimised for the opposite situation; where the common case is that they are available and may block only occasionally. FYI see this thread: https://lkml.org/lkml/2008/4/11/323. Also completions are semantically more explicit in this case. Signed-off-by:

vchiq_init_state() initialises a series of semaphores to then call remote_event_create() on the same semaphores, which initializes them again. We get rid of the second initialization. Signed-off-by:

vchiq_init_state() checks the initial contents of slot_zero are correct. These are set in vchiq_init_slots(), using the same hard-coded defaults as the checks. Both functions are called sequentially and Video Core isn't yet aware of the slot's address. There is no way the contents of slot_zero changed in between functions, making the checks useless.

VCHIQ bulk transfers are what most people call DMA transfers. The CPU sends a list of physical addresses to the VideoCore which then access the memory directly without the need for CPU interaction. With this setup we call the CPU the "slave" and the VideoCore the "master". There seems to be an option to switch roles in vchiq. Which nobody is using nor is properly implemented. So we get rid of the "is_master == 1" option, and all the related code. Signed-off-by:

The function is passed to vchiq_core.c for it to go trough all the transfer elements (an array of pointers to data) and copy them into the actual transfer memory (contiguous memory). The logic in the function was "copy an element and return, except when the element is empty, in which case look for the next non-empty element and copy it. The function will be called as many times as necessary until all the elements are copied". Now, this approach already forces the function to loop around elements and felt convoluted, so it was changed to a more straightforward "Copy all the elements into memory as long as they fit". The resulting function is shorter and simpler. Signed-off-by:

The concept of VCHI_MEM_HANDLE_T is introduced by this header file and was meant to be used with bulk transfers. After a quick look in vchiq_core.c it is pretty clear that it actually accomplishes nothing nor alters the bulk transfers in any way. Signed-off-by:
