[RFC][PATCH 0/2] ALSA: control: export all of TLV related macros to user land

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Currently, TLV related protocol is not shared to user land. This is not
good in a point of application interfaces, because application developers
can't realize the protocol just to see UAPI headers.

For this purpose, this patchset moves all of macros related to TLV to UAPI
header. As a result, a header just for kernel land is obsoleted. When adding
new items to the protocol, it's added to the UAPI header. This change affects
some drivers in media subsystem.

In my concern, this change can break applications. When these macros are
already defined in application side and they includes tlv UAPI header
directly, 'redefined' warning is generated at preprocess time. But the
compilation will be success itself. If these two macros have different
content, the result of preprocess is dominated to the order to define.
However, the most applications are assumed to use TLV feature via libraries
such as alsa-lib, thus I'm optimistic to this concern.

As another my concern, the name of these macros are quite simple, as
'TLV_XXX'. It might be help application developers to rename them with a
prefix, as 'SNDRV_CTL_TLV_XXX'. (But not yet. I'm a lazy guy.)
