That's complete overkill, just statically allocate the array in
the amdgpu_ctx structure.
The maximum instance should be 4 IIRC, so something like "struct
amdgpu_ctx_entity *entities[AMDGPU_HW_IP_NUM][4];" so a maximum
of 288 bytes used.
Only alternative I see would be to allocate the array behind the
structure, see dma_resv_list_alloc() for an example on how to do
this. But I don't think that this is worth it.
Resent with added
+#define AMDGPU_MAX_ENTITY_NUM 4
Yes, of course that is certainly a good idea as well.
