In next-20130808, building tegra_defconfig for ARM yields:
drivers/built-in.o: In function `drm_lastclose': /home/swarren/shared/git_wa/kernel/kernel.git/drivers/gpu/drm/drm_drv.c:198: undefined reference to `drm_agp_clear'
That's because drm_agp_clear() is called unconditionally, yet is only conditionally built into drm_agpsupport.c (#if __OS_HAS_AGP).
Should the call from drm_drv.c be conditional, or should there be a dummy static inline replacement in include/drm/drmP.h for when AGP support isn't available?
Sorry, I missed testing with AGP=n and the code I fixed depended on dead-code-elimination to link correctly. I overlooked that. There is a patch pending on dri-devel: http://lists.freedesktop.org/archives/dri-devel/2013-August/043077.html
That makes it worse! To solve it, you need:
Argh! I need some proper build environments to test all the non-x86 stuff. Thanks for the hint, I will resend the patch. Hopefully it'll work this time. Sorry for that..
Thanks David
