At the moment, accel drivers can be built-in even with CONFIG_DRM=m, but this causes a link failure: x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_dev_init': ivpu_drv.c:(.text+0x1535): undefined reference to `drmm_kmalloc' x86_64-linux-ld: ivpu_drv.c:(.text+0x1562): undefined reference to `drmm_kmalloc' x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_remove': ivpu_drv.c:(.text+0x1faa): undefined reference to `drm_dev_unregister' x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_probe': ivpu_drv.c:(.text+0x1fef): undefined reference to `__devm_drm_dev_alloc' The problem is that DRM_ACCEL is a 'bool' symbol, so driver that only depend on DRM_ACCEL but not also on DRM do not see the restriction to =m configs. To ensure that each accel driver has an implied dependency on CONFIG_DRM, enclose the entire Kconfig file in an if/endif check.

Framework for device drivers of compute acceleration devices, such
|
|
as, but not limited to, Machine-Learning and Deep-Learning
|
|
acceleration devices.
|
|
If you say Y here, you need to select the module that's right for
|
|
your acceleration device from the list below.
|
|
This framework is integrated with the DRM subsystem as compute
|
|
accelerators and GPUs share a lot in common and can use almost the
|
|
same infrastructure code.
|
|
Having said that, acceleration devices will have a different
|
|
major number than GPUs, and will be exposed to user-space using
|
|
different device files, called accel/accel* (in /dev, sysfs
|
|
and debugfs).
