Add interface for applications to get information array. The application provides a buffer pointer along with information type, maximum number of entries and maximum size of each entry. The buffer may also contain match conditions based on the information type. After the ioctl completes, the actual number of entries and entry size are returned. (see [1], used by driver runtime library) [1] https://github.com/amd/xdna-driver/blob/main/src/shim/host/platform_host.cpp#L337 Reviewed-by: Mario Limonciello (AMD) <superm1@kernel.org> Reviewed-by: Maciej Falkowski <maciej.falkowski@linux.intel.com> Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Link: https://lore.kernel.org/r/20250903053402.2103196-1-lizhi.hou@amd.com
