Hi Dave, After merging the drm tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c: In function 'create_queue_cpsch': drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c:888:2: error: implicit declaration of function 'init_sdma_vm' [-Werror=implicit-function-declaration] init_sdma_vm(dqm, q, qpd); ^ Caused by commit 3e3f6e1a90a8 ("drm/amdkfd: make the sdma vm init to be asic specific"). I have used the drm tree from next-20150519 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
