linux.git/arch/tile/lib/cacheflush.c, branch v2.6.39 Linux kernel source tree arch/tile: enhance existing finv_buffer_remote() routine 2011-03-01T21:21:06+00:00 Chris Metcalf cmetcalf@tilera.com 2011-02-28T20:48:39+00:00 63b7ca6b04427aea9075d6f5f5f15b82e115bce4 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> 
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.

arch/tile: Split the icache flush code off to a generic <arch> header. 2010-07-06T17:41:46+00:00 Chris Metcalf cmetcalf@tilera.com 2010-06-25T21:03:27+00:00 c78095bd8c77fca2619769ff8efb639fd100e373 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.
