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.

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.
