Chris Metcalf	dbb434214e	arch/tile: disable GX prefetcher during cache flush ... Otherwise, it's possible to end up with the prefetcher pulling data into cache that the code believes has been flushed. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>	2011-05-04 14:40:46 -04:00
Chris Metcalf	63b7ca6b04	arch/tile: enhance existing finv_buffer_remote() routine ... It now takes an additional argument so it can be used to flush-and-invalidate pages that are cached using hash-for-home as well those that are cached with coherence point on a single cpu. This allows it to be used more widely for changing the coherence point of arbitrary pages when necessary. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>	2011-03-01 16:21:06 -05:00
Chris Metcalf	c78095bd8c	arch/tile: Split the icache flush code off to a generic <arch> header. ... This code is used in other places in our system than in Linux, so to share it we now implement it as an inline function in our low-level <arch> headers, and instantiate it in one file in Linux's arch/tile/lib. The file is now cacheflush.c and is C code rather than the strangely-named and assembler-implemented __invalidate_icache.S.
