Rander Wang 0b537cba4d ipc4: init gain & mixin components for zephyr
Fix issue of ipc4 pipeline initialization with zephyr enabled.
Need to initialize these two components. Gain module is another
type of volume without peak volume support and mixin has subset
function of mixer.

Kai Vehmanen f1e3c934f0 zephyr: use z_init_cpu() if Zephyr 3.0.99 or newer
Use the new interface to initialize non-primary cores before
enabling them with arch_start_cpu(). This interface is not
available in Zephyr 3.0.0, but is mandatory in later release.

Depends on Zephyr commit 2b210cb3db05 ("kernel: Refactor SMP cpu

Kai Vehmanen 760f5ddea2 zephyr: fix race in secondary core power-up
z_wrapper_cpu_enable_secondary_core() may be called
repeatedly on a core that is already running. Add a check
to ensure we do not try to restart a core that is already
running.

Also add a check for ready_flag as done in upstream Zephyr
kernel/smp.c to ensure z_wrapper_cpu_enable_secondary_core()
does not return until the target core has finished its
startup and arch_cpu_active() returns true.

Kai Vehmanen 378d7b7822 zephyr: always use Zephyr interface to power up secondary cores
Currently there is code to power up secondary cores both
in Zephyr architecture hooks in wrapper.c, as well as in
SOF runtime-PM driver.

Some of this is necessary overlap until full replacement of
SOF runtime-PM is available. But for secondary core power up,
we can already clean up the flow and hook the Zephyr core
enable code to runtime-PM driver directly. This fixes startup
issues seen on Intel cAvS2.5 platforms.

Core power-down is left intentionally for runtime-PM driver
to handle as the related interface in Zephyr is not ready
for use yet.

Bartosz Kokoszko ec63f3a70e pm_runtime: prepare secondary cores for power down in d0->d0ix flow
Primary core during going to D0i3 state disables all another cores
in platform_pg_int_handler() function. Before it secondary cores
should be prepared (disable interrupts, perform writeback) in order
to make proper restore flow after D0i3->D0 transition.

This commit adds cpu_secondary_cores_prepare_d0ix() function in
ipc_pm_gate() handler, which sends idc to secondary cores
with information that they should perform preparation for power down
in the next platform_wait_for_interrupt() invocation. In
platform_wait_for_interrupt() there is cpu_power_down_core()
invocation with CPU_POWER_DOWN_MEMORY_ON (performs writeback/invalidate,
disables interrupts), when proper flag is set.

Andy Ross f0415135ea zephyr: Correct heap cache management
The heap code was invalidating blocks on allocation, but that's the
wrong side of the pipe.  By definition, new heap memory
will/should/must be written before being used (because the memory is
undefined), so any cached contents are irrelevant as they'll be
overwritten.

But when the user is finished with the block and frees it, there may
still be live dirty cache lines in the region on the current CPU.
Those must be invalidated, otherwise they will be evicted from the
cache at some point in the future, on top of the memory region now
being used for different purposes on another CPU.

Remove the invalidate on allocation.  Add it back in free.  Leverage a
new Zephyr sys_heap_usable_size() routine to get the size so we don't
have to store it in an extra header.

Tests with dynamic-pipeline topologies increase the complexity

with cached heap disabled shows no failures.

The cached heap is already disabled for IMX targets, so build on

Fixes #4356

In XTOS SOF, ipc_send_queued_msg() is run by task_main_primary_core(),
the initialization of which has a hard and circular dependency with the
initialization of the EDF scheduler. This EDF scheduler is not part of

using a notifier triggered by the periodic Low Latency scheduler.

Kai Vehmanen 985c5b5685 zephyr: split the heap into shared and non shared
To increase performance of audio application code, the SOF heap should
be mapped to cached address region on platforms with aliased
cached/uncached memory layout.

This splits the heap into two and maps the SOF_MEM_ZONE_BUFFER to
the cached heap and all rest to uncached heap.

The raw heap memory area is still mapped to uncached memory, even for
the cached heap. The allocated blocks are converted to cached addresses
and passed to SOF users of rmalloc() and rballoc_align(). To ensure
application buffers do not share cachelines with heap metadata chunks,
allocation sizes are rounded up to integer multiples of platform
cacheline size.
