Adds start delay for timer driven capture streams.
External interface is enabled after DMA, so we need to compensate it.

It is now unused so remove it. Notice that we
also remove temp var msg.

Simple variable declarations with no initialisation don't need to
be protected, move them out of a spin-lock. Also remove superfluous

The system-runtime zone on CAVS system is suitable for DMA, add the
capability to heap descriptors.
Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
Currently only the runtime zone has several heaps with different
capabilities on some systems. So that if a memory allocation request
is made from that zone, a suitable heap is selected. Additionally,
if the request cannot be satisfied from the runtime heap, an attempt
is made to satisfy it from the buffer heap. The other two zones -
system and system-runtime - have per-core heaps with identical
capabilities. If the request to one of those zones cannot be
satisfied from it, no attempt is made to allocate memory from a
different zone. Supposedly because of this determinism no capability
check is performed. This is wrong, since if capabilities don't match
it should be assumed, that the obtained memory will not be suitable
for the designated purpose. This patch adds the missing checks.
Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
The block allocation algorithm, as implemented in _balloc(), is first
trying to find a single free memory block to satisfy the request. If
that fails it is then trying to allocate several blocks in a
sequence. That part is implemented wrongly. It can end up allocating
multiple such block sequences, and not using but leaking them
instead. This patch first simplifies the search for a single suitable
buffer, then fixes the leakage.

In _balloc() if no heap was found, no need to jump to a location in
the function, where a potentially successful allocation is still
being processed, jump directly to the unlock-and-return point.

If we found a busy block among the potential sequence of blocks, that
we were trying to allocate, no need to retry the attempt from the
next starting block, unless it was the first block, that was busy. It
is enough to resume searching from the next block after the busy one.
