Andy Ross 51a5fb9c80 uuid: Add app-global UUID registry
Add a very simple uuid-registry.txt file containing all known UUIDs in
the tree, use it to generate a C header (the script validates it in
the process) that can then be used for a simplified
SOF_DEFINE_REG_UUID() mechanism that avoids the risk and temptation
temptation of components incorrectly implementing UUIDs.

The intent is that in the longer term, this file can be used by other
downstream tooling (manifest and topology generation) to more easily
reference known IDs by name in a way that avoids duplication and
error.

Andy Ross a3c1b75808 uuid: Rename DECLARE_SOF(_RT)?_UUID() -> SOF_DEFINE_UUID()
Complete the unification of the diverged UUID APIs with a big rename.
Call it "DEFINE" instead of "DECLARE" since this is in fact a C struct
definition and not just a declaration of a type or extern symbol.

Kai Vehmanen 1a7a36a84c sof-logger: ensure NULL string is not passed to printf/fprintf
Due to allocation failures, or invalid content in dictionary,
"params" entries in "struct proc_ldc_entry" may be NULL.

In print_entry_params(), the NULL entries may be passed
as arguments to fprintf(). While e.g. glibc handles these without
error, this is not guaranteed behaviour and may result in segfault
on some platforms.

Fix the issue by aborting program if allocation fails and
explicitly handling the cases when asprintf_entry_text returns
NULL.

Liam Girdwood 1629a1f72c header: rtos: decouple headers into rtos specific directories.
No functional runtime change, but changes to rtos partitioning and the
layout of headers .

This patch creates RTOS specifc header paths and updates spinlock.h
and kernel.h to show the new usage. Other headers will incrementally follow.
It reuses the current zephyr topleve directory and creates a new
toplevel xtos directory for xtos specific files.

Due to the mixing of RTOS, driver and library headers at the top level include
directory it was necessary to create rtos specific header directories i.e.

src/include/rtos-xtos
src/include/rtos-zephyr

These RTOS include directories will eventually contain RTOS specific headers
whilst common logic and structures will be placed in non RTOS directories.

This will also mean

"#include <sof/spinlock.h>"

will become

"#include <rtos/spinlock.h>"

and will allow easier visualisation of where and why RTOS headers are being used.
This will help to eliminate cross usage of headers between RTOSes.

Subsequqnt patches will move more headers and rtos specific wrppaer
source files into rtos specific locations.

Don't fail immediately when the driver is not loaded. Use inotify

Marc Herbert d54a9281f8 logger: print a separator when the timestamp goes back in time
This makes the display of the mailbox ring buffer log much less
confusing. It should not happen with the DMA trace but will behave the
same in case something goes wrong.

Before this commit the only clue that wrapping had happened was a NaN in
the delta column (instead of the negative value).

The "other?" is because the start of the mailbox is sometimes corrupted,
or the timestamp goes sometimes back at boot for no obvious reason. In
other words this new separator is useful to highlight bugs too.

Marc Herbert dc0ab8a449 logger: fix precision bug introduced by new -e option
Add missing "break" so the -e option stops spilling on the -f precision
option. Fixes commit 53ce8b9d9f ("logger: new relative timestamps
option, relative to first entry seen"). Since that commit the -e option
was wrongly assigned to the precision too.

Marc Herbert 53ce8b9d9f logger: new relative timestamps option, relative to first entry seen
Add a new sof-logger -e 0/1 relative timestamps option where the
TIMESTAMP column is relative to the first entry seen.

Removes many digits and makes the TIMESTAMP column much more readable in
short logs.

Also stop showing "NaN" as the first DELTA like something went
wrong. Show zero instead.

The new option is off by default when using -r(aw) and on otherwise.

The first entry is kept always absolute.

Marc Herbert 2e6cafa02f logger: use strerror()
Useful error messages when forgetting to use "sudo" or to change
permissions in udev.

Some places were printing the errno decimal. Others no specific error
at all.

Sample outputs:

error: Unable to open version file /sys/kernel/debug/sof/fw_version: \
                                                       Permission denied
