Title: ibam in 4.x error
Post by: Jason W on August 28, 2011, 10:20:22 PM

Ibam is not working with TC 4.x, seems to be some changes in where the kernel keeps relevant files, a snipped output of strace:

Code: [Select]

open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/apm", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
mkdir("/home/tc/.ibam", 0755)           = -1 EEXIST (File exists)
open("/home/tc/.ibam/ibam.rc", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
write(2, "No apm data available.", 22No apm data available.)  = 22
write(2, "\n", 1
)                       = 1
exit_group(0)                           = ?

Is APM enabled in the 4.x kernel?

Which command line switch was used?

No flags were used, I always just used the command alone.

This patch that gentoo uses on it's package fixes the issue on my box:

I will take a look on the patch. Good to hear it is used!

Yes, there is APM, but newer boxes do not have it.

Recompiled on TC4.0 apllying patch. It works fine. However binary is 470k after stripping resulting a 201k .tcz while TC 3.x build is only 29k.

:( :(
