![]() In case of DSP extension presence in HW some instructions (related to integer multiply, multiply-accumulate, and divide operation) executes on this DSP execution unit. So their execution will depend on dsp configuration register (DSP_CTRL) As we want these instructions to execute the same way regardless of DSP presence we need to set DSP_CTRL properly. NOTE: we do the same adjustments in Linux kernel, see in kernel tree: commit 4827d0cf744e ("ARC: handle DSP presence in HW") Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> |
