linux/lib/iomap_copy.c, branch v2.6.29-rc7

[PATCH] add __iowrite64_copy

2006-06-21T03:24:58Z

Introduce __iowrite64_copy. It will be used by the Myri-10G Ethernet driver to post requests to the NIC. This driver will be submitted soon. __iowrite64_copy copies to I/O memory in units of 64 bits when possible (on 64 bit architectures). It reverts to __iowrite32_copy on 32 bit architectures.

[PATCH] Introduce __iowrite32_copy

2006-02-01T16:53:13Z

This arch-independent routine copies data to a memory-mapped I/O region, using 32-bit accesses. The naming is double-underscored to make it clear that it does not guarantee write ordering, nor does it perform a memory barrier afterwards; the kernel doc also explicitly states this. This style of access is required by some devices. This change also introduces include/linux/io.h, at Andrew's suggestion. It only has one occupant at the moment, but is a logical destination for oft-replicated contents of include/asm-*/{io,iomap}.h to migrate to.
