Re: on-going discussion at [1], I've added support to EDMA driver to be
able to accept scatter gather lists of arbitrary length, but still make
use of only a certain MAX number of slots. Thus free-ing up the rest of
the slots to other slave users. With this there is no need for slave
drivers to
Dummy slot has been used as a way for missed-events not to be
reported as missing. This has been particularly troublesome for cases
where we might want to temporarily pause all incoming events.
For EDMA DMAC, there is no way to do any such pausing of events as
the occurence of the next event is
Process SG-elements in batches of MAX_SG_NR if they are greater
than MAX_SG_NR. Due to this, at any given time only those many
slots will be used in the given channel no matter how long the
scatter list is. We keep track of how much has been written
inorder to process the next batch of elements in
In an effort to move to using Scatter gather lists of any size with
EDMA as discussed at [1] instead of placing limitations on the driver,
we work through the limitations of the EDMAC hardware to find missed
events and issue them.
The sequence of events that require this are:
For the scenario
Changes are made here for configuring existing parameters to support
DMA'ing them out in batches as needed.
Also allocate as many as slots as needed by the SG list, but not more
than MAX_SG_NR. Then these slots will be reused accordingly.
For ex, if MAX_SG_NR=10, and number of SG entries is 40,
Manual trigger for events missed as a result of splitting a
scatter gather list and DMA'ing it in batches. Add a helper
function to trigger a channel incase any such events are missed.

Hi,
Unfortunately I'm no longer able to manually track regressions and posted
solutions (if any). This process consumes more time and energy than I'm
able to invest now. So, starting with v3.11-rc1, the summary reports will
only report the outcome of automated validation scripts.
