All: I am having problems running on an 860 based card when reading and writing buffers for drivers and for user space applications. Currently I am using the invalidate and flush cache calls when READING and WRITING from/to the alloc'd memory during these situations.
Is there a way to alloc memory and mark it as cache inhibited ? This would eliminating the need for the invalidate and flush calls. I am currently running a 2.2.14 version of the kernel on an 860 processor. I've already tried using the m8xx_cpm_hostalloc() function in the arch/ppc/8xx_io/commproc.c file. This does not seem to work, as the memory returned does not seem to be cache inhibited. I still need to flush and invalidate these regions. Any ideas ?
