* ohci: Rework bus glue integration to allow several at onceSylvain Munaut2007-02-0713-198/+80
| | | | | | | | | | | | | | | | | The previous model had the module_init & module_exit function in the bus glue .c files themselves. That's a problem if several glues need to be selected at once and the driver is built has module. This case is quite common in embedded system where you want to handle both the integrated ohci controller and some extra controller on PCI. The ohci-hcd.c file now provide the module_init & module_exit and appropriate driver registering/unregistering is done conditionally, using #ifdefs.

* rndis_host learns ActiveSync basicsOle Andre Vadla Ravnas2007-02-074-31/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Windows Mobile 5 based devices described as supporting "ActiveSync": - Speak RNDIS but lack the CDC and union descriptors. This patch updates the cdc ethernet code to fake ACM descriptors we need. - Require RNDIS_MSG_QUERY messages to include a buffer of the size the response should generate. This patch updates the rndis host code to pass this will-be-ignored data. The resulting RNDIS host code has been reported to work with several WM5 based devices. (Note that a fancier patch is available at synce.sf.net.) Some bugfixes, affecting not just ActiveSync: (a) when cleaning up after RNDS init fails, scrub the second interface just like cdc_ether does, so disconnect won't oops. (b) handle peripherals that use the pad-to-end-of-packet option; some devices can't talk to us if that option doesn't work. (c) when choosing configurations, don't forget about an RNDIS config just because the RNDIS driver is dynamically linked. Cleanup, streamlining, bugfixes, Kconfig, and matching hub driver update. Also for paranoia's sake, refuse to talk to something that looks like a real modem instead of RNDIS.

* USB: ethernet gadget interop with MCCI Windows driverDavid Brownell2007-02-071-39/+103
| | | | | | | | | | | | | | | | | | It turns out that minor tweaks to the "CDC Subset" support in the Ethernet gadget driver, just updating a config descriptor, let it be automagically recognized by a Windows driver supported by MCCI. This patch adds those descriptors, so systems using PXA 255 processors (like Gumstix etc) can interop with those commercial MS-Windows drivers. This is a Good Thing since Microsoft's RNDIS code has bugginess issues, which are unfortunately compounded by "won't fix" issues as well as "the published specs are incomplete and wrong" issues. Being able to talk to the MCCI driver gives Windows users another connectivity option. (MCCI also has CDC Ethernet drivers, which can help most non-PXA processors.)

| | | | | | | | | | | | | | | | | | This patch implements supports for EHCI controllers whose MMIO registers are big endian and enables that functionality for the Toshiba SCC chip. It does _not_ add support for big endian in-memory data structures as this is not needed for that chip and I hope it will never be.

Add this quirk and HID_QUIRK_MULTI_INPUT to 0810:0001. PantherLord Twin USB Joystick, 0810:0001 has separate input reports for 2 distinct game controllers in the same interface, so it needs HID_QUIRK_MULTI_INPUT. However, the device also contains one output report per controller which is used to control the force feedback function, and we do not want those to appear as separate input devices as well. The simplest approach seems to be to add a quirk to skip output reports on 0810:0001, and allow the force feedback driver to handle those.

The ib_addr netevent callback routine, however, currently only acts on InfiniBand neighbour updates. It needs to act on ethernet neighbour updates as well.

When the QP is in the error state it is obvious that there will be no response so it is quite useless to wait. In fact, the timeout causes SRP to wait a long time to reconnect when a QP error occurs. (Each abort and each reset_device calls send_tsk_mgmt, which waits for the timeout). The following patch solves this problem by identifying the failure and returning an immediate error code.

The following patch replaces this with the pointer to qp itself, and updates all low level drivers and all users. This has the following advantages: - Ability to get a per-qp context through wc->qp->qp_context - Existing drivers already have the qp pointer ready in poll cq, so this change actually saves a tiny bit (extra memory read) on data path (for ehca it would actually be expensive to find the QP pointer when polling a CQ, but ehca does not support SRQ so we can leave wc->qp as NULL for ehca) - Users that need the QP number can still get it through wc->qp->qp_num Use case: In IPoIB connected mode code, I have a common CQ shared by multiple QPs. To track connection usage, I need a way to get at some per-QP context upon the completion, and I would like to avoid allocating context object per work request just to stick a QP pointer into it. With this code, I can just use wc->qp->qp_context. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * | tifm_7xx1: switch from workqueue to kthreadAlex Dubov2007-02-042-68/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As there's only one work item (media_switcher) to handle and it's effectively serialized with itself, I found it more convenient to use kthread instead of workqueue. This also allows for a working implementation of suspend/resume, which were totally broken in the past version.
