rapidio/tsi721: fix bug in register offset definitions

2012-03-19T16:02:35Z

commit 9bbad7da76b3dd578fb55c862624366a8c9ccd22 upstream. Fix indexed register offset definitions that use decimal (wrong) instead of hexadecimal (correct) notation for indexing multipliers. Incorrect definitions do not affect Tsi721 driver in its current default configuration because it uses only IDB queue 0. Loss of inbound doorbell functionality should be observed if queue other than 0 is used.

rapidio/tsi721: fix queue wrapping bug in inbound doorbell handler

2012-03-12T19:31:27Z

commit b24823e61bfd93d0e72088e4f5245287582ed289 upstream. Fix a bug that causes a kernel panic when the number of received doorbells is larger than number of entries in the inbound doorbell queue (current default value = 512). Another possible indication for this bug is large number of spurious doorbells reported by tsi721 driver after reaching the queue size maximum.

rapidio/tsi721: modify PCIe capability settings

2011-12-09T15:50:29Z

Modify initialization of PCIe capability registers in Tsi721 mport driver: - change Completion Timeout value to avoid unexpected data transfer aborts during intensive traffic. - replace hardcoded offset of PCIe capability block by making it use the common function. This patch is applicable to kernel versions starting from 3.2-rc1. Signed-off-by: Alexandre Bounine Cc: Matt Porter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rapidio/tsi721: fix mailbox resource reporting

2011-12-09T15:50:29Z

Bug fix for Tsi721 RapidIO mport driver: Tsi721 supports four RapidIO mailboxes (MBOX0 - MBOX3) as defined by RapidIO specification. Mailbox resources has to be properly reported to allow use of all available mailboxes (initial version reports only MBOX0). This patch is applicable to kernel versions staring from 3.2-rc1.

rapidio/tsi721: switch to dma_zalloc_coherent

2011-12-09T15:50:29Z

Replace the pair dma_alloc_coherent()+memset() with the new dma_zalloc_coherent() added by Andrew Morton for kernel version 3.2 Signed-off-by: Alexandre Bounine Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

RapidIO: add mport driver for Tsi721 bridge

2011-11-02T23:07:01Z

Add RapidIO mport driver for IDT TSI721 PCI Express-to-SRIO bridge device. The driver provides full set of callback functions defined for mport devices in RapidIO subsystem. It also is compatible with current version of RIONET driver (Ethernet over RapidIO messaging services). This patch is applicable to kernel versions starting from 2.6.39.
