To be able to run DSP-enabled userspace applications with AGU (address generation unit) extensions we additionally need to save and restore following registers at context switch: * AGU_AP* * AGU_OS* * AGU_MOD* Reviewed-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
