Questions about memory cache control

changhee — Sat, 08 Jan 2005 02:06:50 GMT

First of all, thanks for your reading.

I havetwo questions about memory cache control.

"1. Do store buffers operate when disabling caches?"

"2.Ifsome memory regions are set to WC(write combining), dothe readsto the regionsrefer to write combining buffers, not to memory? If the reads refer to write combining buffers, is it possible toflush the buffer explicitly?"

If you have any idea, please let me know.

I look forward to replying.
