Build compat-wireless for linus tree

Build compat-wireless for linus tree

[Shuo]

Hi list,
How could i get the latest compat-wireless code and compile against
an new kernel which pull from linus' tree?
I am using v3.7-rc4. It seems there is no ready compat-wireless code
for it. Is there any repo for this?

Any comment would be appreciated!

Hi Shuo,

compat-drivers compiles for me against kernel 3.7-rc6 without any
problems. Try out the latest version:

Hi Shuo,

There seams to be something wrong with your kernel. The include done in
include/linux/pm_qos.h:9:0 should not happen on your kernel version.

Does include/generated/uapi/linux/version.h in your kernel directory
contains #define LINUX_VERSION_CODE 197895 or does it contain some other
number?

The problem had been resolved.
There is an old LINUX_VERSION_CODE in the version.h. So i clean the
kernel tree and make a full compile again. The errors above went away.
Another thing is i found the latest compat driver contains some
graphics drivers. When i install a wireless driver, such as b43, the
graphics drivers also will be installed. That will break my original
in-tree graphic drivers dep and caused some issue when X startup.
So now, i turn to use latest wireless and graphic in-tree drivers with
the latest kernel. They work well.
Thanks, again!
