rapidio/rionet: rework driver initialization and removal

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

Rework probe/remove routines to prevent rionet driver from monopolizing
target RapidIO devices.  Fix conflict with modular RapidIO switch drivers.

Using one of RapidIO messaging channels rionet driver provides a service
layer common to all endpoint devices in a system's RapidIO network.  These
devices may also require their own specific device driver which will be
blocked from attaching to the target device by rionet (or block rionet if
loaded earlier).  To avoid conflict with device-specific drivers, the
rionet driver is reworked to be registered as a subsystem interface on the
RapidIO bus.

The reworked rio_remove_dev() and rionet_exit() routines also include
handling of individual rionet peer device removal which was not supported
before.

ethtool: fix drvinfo strings set in drivers

2013-01-07T05:06:31+00:00

Use strlcpy where possible to ensure the string is \0 terminated.
Use always sizeof(string) instead of 32, ETHTOOL_BUSINFO_LEN
and custom defines.
Use snprintf instead of sprint.
Remove unnecessary inits of ->fw_version
Remove unnecessary inits of drvinfo struct.

rapidio/rionet: rework to support multiple RIO master ports

2012-10-05T18:05:23+00:00

Make RIONET driver multi-net safe/capable by introducing per-net lists of
RapidIO network peers.  Rework registration of network adapters to support
all available RIO master port devices.

rapidio/rionet: fix multicast packet transmit logic

2012-10-05T18:05:19+00:00

Fix multicast packet transmit logic to account for repetitive transmission
of single skb:
- correct check for available buffers (this bug may produce NULL pointer
  crash dump in case of heavy traffic);
- update skb user count (incorrect user counter causes a warning dump from
  net_tx_action routine during multicast transfers in systems with three or
  more rionet participants).

rionet: fix page allocation order of rionet_active

2012-04-02T03:17:16+00:00

rionet_active is allocated from the page allocator and the allocation
order is calculated on the assumption that the page size is 4KB, so it
wastes memory on more than 4K page systems.

rapidio: fix use of non-compatible registers

2011-08-25T23:25:34+00:00

Replace/remove use of RIO v.1.2 registers/bits that are not
forward-compatible with newer versions of RapidIO specification.

RapidIO specification v.1.3 removed Write Port CSR, Doorbell CSR,
Mailbox CSR and Mailbox and Doorbell bits of the PEF CAR.

Use of removed (since RIO v.1.3) register bits affects users of
currently available 1.3 and 2.x compliant devices who may use not so
recent kernel versions.

Removing checks for unsupported bits makes corresponding routines
compatible with all versions of RapidIO specification.  Therefore,
backporting makes stable kernel versions compliant with RIO v.1.3 and
later as well.
