Here is the version 5 of the change to export OMAP data to userspace
(name, revision, id code, production id and die id).
Basically, this version is still attempting to create a new file under /proc.
It is the /proc/socinfo, which should be used to export bits which are SoC specific
(not CPU related, nor machine related).
So, differences between previous version are:
- merged patch 02/04 with 03/04 to avoid compilation breakages.
- simplified the seq_file usage by using the single_open and single_release functions
- exported a function to register a seq_operation .show callback
- adapted the changes accordingly
As usual, comments are welcome.
Eduardo, what has happened to this patchset?
Got forgotten :-(. Unfortunately I didn't pushed it hard enough.
I propose to refactor your patchset, moving from procfs to sysfs.
Do you want help in picking it up and try to polish it up?
Yeah, but it would need a refactoring. IIRC, result of last discussion was that
we should not mess with /proc. So, maybe moving back to something under sysfs.
Perhaps /sys/devices/soc or so?
About the location of this new sysfs entry, where do you think it should be?
I propose to create a new directory named "soc" in /sys/devices/system/.
As platform vendors have several/different kind of IDs to export to
sysfs, I propose each vendor to create file entries related to their IDs
(eg. /sys/devices/system/soc/idcode for OMAP platforms).
However, I think we should have a common file entry to export the unique
ID of the platforms. Indeed, user-space applications should have a
unified way to get this kind of ID, regardless of the platform (eg.
/sys/devices/system/soc/unique_id).
Do you agree with my proposal?
Thanks for your comments.

Maxime Coquelin
