Dear Bernd Kuhls, On Sat, 19 Dec 2015 17:53:35 +0100, Bernd Kuhls wrote: > config BR2_PACKAGE_XDRIVER_XF86_VIDEO_NOUVEAU > bool "xf86-video-nouveau" > depends on BR2_PACKAGE_MESA3D > + # package depends on DRI support in xserver_xorg-server > + # libdrm locking macros use armv6+ instructions on arm > + depends on !BR2_ARM_CPU_ARMV4 && !BR2_ARM_CPU_ARMV5 > select BR2_PACKAGE_MESA3D_DRI_DRIVER_NOUVEAU > select BR2_PACKAGE_LIBDRM > select BR2_PACKAGE_LIBDRM_NOUVEAU I don't quite understand this one. Where are these locking macros implemented? In the nouveau xf86 driver? In the libdrm nouveau part? In the mesa3d nouveau part? The way you worded the comment makes me think it's in libdrm (but I was unable to find those macros). And if they are in libdrm, then the dependency should also be used for the libdrm package. Could you clarify? Thanks, Thomas

In > the mesa3d nouveau part? the limitation comes from xserver_xorg-server: https://git.busybox.net/buildroot/tree/package/x11r7/xserver_xorg-server/ xserver_xorg-server.mk#n133 xdriver_xf86-video-nouveau needs DRI support enabled in the xserver_xorg- server package, this is only true in this case: ifeq ($(BR2_PACKAGE_MESA3D_DRI_DRIVER)n$(BR2_ARM_CPU_ARMV4) $(BR2_ARM_CPU_ARMV5),yn) I ported this limitation (no DRI support for armv4/5) to package/x11r7/ xdriver_xf86-video-nouveau/Config.in with this patch, along with the comment from xserver_xorg-server.mk and a reference to the xserver_xorg- server package to fix your build error on armv5: http://article.gmane.org/gmane.comp.lib.uclibc.buildroot/135186 Regards, Bernd
