arch/tile: disable GX prefetcher during cache flush

2011-05-04T18:40:46+00:00

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

arch/tile: enhance existing finv_buffer_remote() routine

2011-03-01T21:21:06+00:00

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

arch/tile: Split the icache flush code off to a generic header.

2010-07-06T17:41:46+00:00

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 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. Signed-off-by: Chris Metcalf Acked-by: Arnd Bergmann
