Subject: i915 fails to build on 32bit Systems
Date: Wed, 13 Mar 2013 19:33:42 +0100 [thread overview]
Message-ID: <20130313183342.GA7484@debian> (raw)
i915.ko does not build due to the following function in i915_debugfs.c:
i915_min_freq_set(void *data, u64 val)
{
...
dev_priv->rps.min_delay = val / GT_FREQUENCY_MULTIPLIER;
...
}
Doing a 64bit integer division on 32bit requires a
compiler run time library to be linked in, otherwise
the symbol __udivdi3 will be missing.
This was introduced with
commit 2389cc5006861a8e024a23cb73605f2ab6a5afe8
Author: Kees Cook <keescook@chromium.org>

drm/i915: use simple attribute in debugfs routines
before this val was a simple int.
Cheers,
Egbert.
