rapidio: update for destination ID allocation

2012-10-10T23:50:15Z

Address comments provided by Andrew Morton: https://lkml.org/lkml/2012/10/3/550 - Keeps consistent kerneldoc compatible comments style for new static functions. - Removes unnecessary complexity from destination ID allocation routine. - Uses kcalloc() for code clarity.

rapidio: add destination ID allocation mechanism

2012-10-05T18:05:23Z

Replace the single global destination ID counter with per-net allocation mechanism to allow independent destID management for each available RapidIO network. Using bitmap based mechanism instead of counters allows destination ID release and reuse in systems that support hot-swap.

rapidio: use device lists handling on per-net basis

2012-10-05T18:05:22Z

Modify handling of device lists to resolve issues caused by using single global list of RIO devices during enumeration/discovery. The most common sign of existing issue is incorrect contents of switch routing tables in systems with multiple mport controllers while single-port configuration performs as expected.

rapidio: add inbound memory mapping interface

2012-10-05T18:05:21Z

Add common inbound memory mapping/unmapping interface. This allows to make local memory space accessible from the RapidIO side using hardware mapping capabilities of RapidIO bridging devices. The new interface is intended to enable data transfers between RapidIO devices in combination with DMA engine support. This patch is based on patch submitted by Li Yang (https://lists.ozlabs.org/pipermail/linuxppc-dev/2009-April/071210.html) Signed-off-by: Alexandre Bounine Cc: Matt Porter Cc: Li Yang Cc: Kumar Gala Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rapidio/tsi721: modify mport name assignment

2012-10-05T18:05:20Z

Modify RapidIO mport device name assignment to include device name of PCIe side of Tsi721 bridge. The new name format is intended to provide definitive reference between RapidIO and PCIe sides of the bridge in systems with multiple Tsi721 bridges.

rapidio: add DMA engine support for RIO data transfers

2012-06-01T00:49:31Z

Adds DMA Engine framework support into RapidIO subsystem. Uses DMA Engine DMA_SLAVE interface to generate data transfers to/from remote RapidIO target devices. Introduces RapidIO-specific wrapper for prep_slave_sg() interface with an extra parameter to pass target specific information. Uses scatterlist to describe local data buffer. Address flat data buffer on a remote side.

RapidIO/mpc85xx: fix possible mport registration problems

2011-04-14T23:06:56Z

Fix a possible problem with mport registration left non-cleared after fsl_rio_setup() exits on link error. Abort mport initialization if registration failed. This patch is applicable to 2.6.39-rc1 only. The problem does not exist for earlier versions.
