With the introduction of variables in the topology files, validation of
attributes values must be done after they are expanded to their defined
values. Also, since valid values for attributes in the class definition
can also be variables, they need to be expanded as well. So, first expand
the attribute values and then check them against expanded valid values.

The recent change to add the background config broke the color setup
via the config file due. Fix the regression by restoring the

Remove the call to snd_config_expand_custom() to expand the top-level
input config. And replace it with calls to snd_config_evaluate_string()
for each non-compound config while processing individual objects. This
will allow retreving variable definitions from object attribute values
and global definitions.
Add a new field "current_obj_cfg" to hold the current object config
being pre-processed.
This will facilitate adding simple math expressions for computing
attribute values for objects based on other attributes. For ex: we can
set the expression for buffer size as follows:
buffer_size "$[($in_channels * 48) * 4]"
The buffer_size attribute value will be computed with the attribute
value "in_channels" based on the expression above. So if $in_channels =
2, buffer_size will be evaluated to 384.
Additionally this change also permits computing attribute values based
on previously computed values. For example:
buffer_size "$[($in_channels * 48) * 4]"
dma_buffer_size "$[$buffer_size * 2]"
dma_buffer_size will be computed as 768. Note that the order of
definitions for buffer_size and dma_buffer_size matters because the
evaluation for dma_buffer_size depends on the evaluation of buffer_size.
In order to conform to this, the tplg_object_copy_and_add_param() is
modified to add attribute configs from class config to an object using
snd_config_before() instead of snd_config_add().
With this change, we no longer need to set the auto_attr_updater for
buffer type widget objects. So remove it.

Add a -D switch to be able to pass pre-processor definitions that will
be used to expand arguments in the input config file. This will be
useful to generate multiple topology binaries from the same input config
file with different argument values.
For example: if we had a pipeline config as follows:
Object.Pipeline {
volume-playback.1 {
dynamic_pipeline $DYNAMIC_PIPELINE
}
}
We can define the variable for DYNAMIC_PIPELINE as:
Define {
DYNAMIC_PIPELINE 0
}
And when pre-processing the conf file pass "-D DYNAMIC_PIPELINE=1" to
override the default value for dynamic_pipeline attribute in the input
conf file.

The recent commit c867aa8a84 ("alsamixer: use background color
instead of COLOR_BLACK") changed the behavior of alsamixer to take the
system default background color instead of black. This caused
problems on the terminal setups that have bright background colors,
e.g. yellow is very hard to read.
It could be "fixed" by setting up the color configurations in
~/.config/alsamixer.rc, but this needs to change the all colors in
every element, which is pretty cumbersome. Instead, this patch
extends the config set command to allow user to specify the default
background color. A user like me can create their own
~/.config/alsamixer.rc file containing the line
set background black
and the old good black background is back again.
Note that, for achieving the above, we also had to shuffle the
function call order, to parse the config at first, then initialize
curses. This shouldn't matter for other behavior.

Signed-off-by: Takashi Iwai <tiwai@suse.de>
The handling of 16bit samples in the peak calculations has a bug when
a sample with 0x8000 is passed. As abs() treats 32bit int, it returns
0x8000. And yet the code stores back into 16bit value again.
To fix that overflow, use 32bit value (i.e. val instead of sval) for
the further calculations.
