linux-toradex.git/arch/tile/include/uapi/asm/cachectl.h, branch v3.14.3 Linux kernel for Apalis and Colibri modules tile: convert uses of "inv" to "finv" 2013-07-31T15:51:19+00:00 Chris Metcalf cmetcalf@tilera.com 2013-07-23T21:32:04+00:00 dd78bc11fb2050b6a3990d0421feca4c68ca4335 The "inv" (invalidate) instruction is generally less safe than "finv" (flush and invalidate), as it will drop dirty data from the cache. It turns out we have almost no need for "inv" (other than for the older 32-bit architecture in some limited cases), so convert to "finv" where possible and delete the extra "inv" infrastructure.
