Hi Dave,
After merging the drm tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/gpu/drm/amd/amdkfd/kfd_device.c: In function 'kgd2kfd_device_init':
drivers/gpu/drm/amd/amdkfd/kfd_device.c:193:11: error: 'max_num_of_processes' undeclared (first use in this function)
size += (max_num_of_processes * sizeof(struct pm4_map_process) +
^
drivers/gpu/drm/amd/amdkfd/kfd_device.c:193:11: note: each undeclared identifier is reported only once for each function it appears in
drivers/gpu/drm/amd/amdkfd/kfd_device.c:194:26: error: 'max_num_of_queues_per_process' undeclared (first use in this function)
max_num_of_processes * max_num_of_queues_per_process *
^
Caused by commit b8cbab042cd6 ("drm/amdkfd: Allow user to limit only
queues per device") from Linus' tree interacting with commit
e18e794e6ba0 ("drm/amdkfd: Fixed calculation of gart buffer size") from
the drm tree.
I couldn't easily figure out how to fix this, so I just disabled the
driver using the patch below. Please let me know when it is fixed, or
provide me with a merge fix patch.
