rapidio: modify for rev.3 specification changes

2016-08-02T23:35:37+00:00

Implement changes made in RapidIO specification rev.3 to LP-Serial Physical Layer register definitions: - use per-port register offset calculations based on LP-Serial Extended Features Block (EFB) Register Map type (I or II) with different per-port offset step (0x20 vs 0x40 respectfully). - remove deprecated Parallel Physical layer definitions and related code.

rapidio: convert switch drivers to modules

2013-07-03T23:08:04+00:00

Rework RapidIO switch drivers to add an option to build them as loadable kernel modules. This patch removes RapidIO-specific vmlinux section and converts switch drivers to be compatible with LDM driver registration method. To simplify registration of device-specific callback routines this patch introduces rio_switch_ops data structure. The sw_sysfs() callback is removed from the list of device-specific operations because under the new structure its functions can be handled by switch driver's probe() and remove() routines. If a specific switch device driver is not loaded the RapidIO subsystem core will use default standard-based operations to configure a switch. Because the current implementation of RapidIO enumeration/discovery method relies on availability of device-specific operations for error management, switch device drivers must be loaded before the RapidIO enumeration/discovery starts. This patch also moves several common routines from enumeration/discovery module into the RapidIO core code to make switch-specific operations accessible to all components of RapidIO subsystem.

rapidio/switches: remove tsi500 driver

2013-07-03T23:08:04+00:00

Remove the driver for Tsi500 Parallel RapidIO switch because this device has not been available for several years. Since the first introduction of Tsi500, the parallel RapidIO interface was replaced by the serial RapidIO (sRIO) and therefore there is no value in keeping this driver.

drivers/rapidio: idt_gen2.c is implicitly relying on getting stat.h

2011-10-31T23:31:57+00:00

Upon the trial removal of the implicit presence of module.h, lots of files showed up that were getting the sub-includes by default without calling them out. Fix them in advance. Signed-off-by: Paul Gortmaker

rapidio: fix default routing initialization

2011-05-18T09:55:22+00:00

Fix switch initialization to ensure that all switches have default routing disabled. This guarantees that no unexpected RapidIO packets arrive to the default port set by reset and there is no default routing destination until it is properly configured by software. This update also unifies handling of unmapped destinations by tsi57x, IDT Gen1 and IDT Gen2 switches.
