Hello, Is this needed for CPU0 also? Otherwise I think it would be enough to invalidate the caches when the other cache parameters to save one instruction, they are modified in leon3_secondary_cpu_initialize():
- sparc_leon3_set_cctrl( 0x80000F ); + sparc_leon3_set_cctrl( 0xE0000F ); Regards, Daniel On 02/18/2014 12:53 PM, Sebastian Huber wrote:
