Hi All:
Does any one try to clean/invalidate L2 Dcache for userspace memory?
Program allocated a memory from malloc on userspace.
Tried to pass userspace memory point to kernel and use function
"dma_cache_maint" to flush/invalidate it.
But it's not work.
sys_cacheflush seems only flush L1 and icache only.
It doesn't fit my requirement.
So, I cannot find any solution to clean/invalidate L2 Dcache from user
space.
