How to determine ACPI SF patch version from running kernel?

How to determine ACPI SF patch version from running kernel?

[Bas Mevissen]

Hi all,

(I hope this is not asked before, but the SF mailing list archives are 
not searchable, so I was not able to search really well)

How can I determine the ACPI SF patch number? In the ACPI sources there 
are a few numbers used:

ACPI_CA_VERSION
TOSHIBA_ACPI_VERSION
etc.

Those version numbers tell me the versions of the different modules 
within ACPI. If I understand it correctly, there is currently no way to 
determine the "overall" ACPI patch version (aka the SF patch version) 
from a running kernel and possibly not even from the sources without 
using the time stamp.

If so, I think it should change. Otherwise, please tell me how to 
determine this from the kernels syslog.

Regards,

Bas.

ACPI_CA_VERSION is printed on boot and also iirc in /proc/acpi/info.

It changes every release, except for the most recent one. I should've
updated it but I was in a hurry to go on vacation and didn't.

PS this would've been a good question for acpi-support.

 From acpi-20030730-2.4.22-pre8.diff.gz:

The ACPI_CA_VERSION did change, but not to the number of the patch. My 
question was how to determine the _patch_ version and not just the 
version of the ACPI_CA stuff.

(Maybe I see it wrong, but I guess that ACPI_CA is just one part of the 
whole patch.)

For debugging it really helps if the _patch_ number can be easely 
retrieved from the source and at runtime.

For example, if you only make a change to the Toshiba-specific stuff, 
then I would say keep the ACPI_CA number the same and just update the 
overall patch number.

If I only were asking for _where_ to find it, it was.

Technically you're right but except for the most recent patch (which was
a mistake like I mentioned) ACPI_CA_VERSION gets incremented in every
patch on sf.net so the easiest thing is to just use this to
differentiate between sf.net patches.
