Hi Daniel,

FYI, kernel build failed on

tree: git://people.freedesktop.org/~danvet/drm-intel.git drm-intel-nightly head: faee69aa381f507731eb68d263dcd0d446c1fd58 commit: faee69aa381f507731eb68d263dcd0d446c1fd58 [52/52] Merge remote-tracking branch 'origin/drm-intel-fixes' into drm-intel-nightly config: i386-randconfig-b943 (attached as .config)

Build errors:

drivers/gpu/drm/i915/i915_irq.c:1330:2: error: implicit declaration of function 'i915_get_extra_instdone' [-Werror=implicit-function-declaration]

Hm, seems to compile fine here and afaict the function declaration also exists in that file. Can you please double-check?

Daniel,

It's too late here and I'm traveling these days, I'll check it some time later. It may well be some bug in the build or test system. Sorry for the noise!

Thanks, Fengguang

Fyi I've checked this on:

Daniel, it turns out that the function was sitting in an '#ifdef CONFIG_DEBUG_FS' block..

Indeed, thanks a lot for reporting this. -Daniel
