Subject: Clean/Invalidate L1/L2 DCache on userspace.
Date: Thu, 11 Feb 2010 16:27:16 +0800 [thread overview]
Message-ID: <4B73BF64.7030603@ms1.techarea.org> (raw)
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.
