2013-01-04NET: FEC: dynamtic check DMA desc buff typeFrank Li
MX6 and mx28 support enhanced DMA descriptor buff to support 1588 ptp. But MX25, MX3x, MX5x can't support enhanced DMA descriptor buff. Check fec type and choose correct DMA descriptor buff type. Remove static config CONFIG_FEC_PTP. ptp function will be auto detected. Signed-off-by: Frank Li <Frank.Li@freescale.com> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: David S.

2013-01-04smsc95xx: enable dynamic autosuspendSteve Glendinning
This patch enables USB dynamic autosuspend for LAN9500A. This saves very little power in itself, but it allows power saving in upstream hubs/hosts. The earlier devices in this family (LAN9500/9512/9514) do not support this feature. Signed-off-by: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S.

2013-01-04smsc95xx: eliminate duplicate warnings on io failureSteve Glendinning
The register read/write functions already log a warning if an access fails, so this patch removes the additional warnings logged by callers that don't add any more information. This patch makes the resulting driver smaller by not containing as many warning strings.

Flash template provides instructions to stop, restart and initalize the firmware. These instructions are abstracted as a series of read, write and poll operations on hardware registers. Register information and operation specifics are not exposed to the driver. Driver reads the template from flash and executes the instructions located at pre-defined offsets.

2013-01-02bnx2x: Support PF <-> VF Bulletin BoardAriel Elior
The PF <-> VF Bulletin Board is a simple interface between the PF and the VF. The main reason for the Bulletin Board is to allow the PF to be the initiator. The VF publishes at 'acquire' stage the GPA of a Bulletin Board structure it has allocated. The PF notes this GPA in the VF database. The VF samples the Bulletin Board periodically for new messages. The latest version of the BB is always used. Signed-off-by: Ariel Elior <ariele@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

2013-01-02bnx2x: Support of PF driver of a VF release requestAriel Elior
The 'release' request is the opposite of the 'acquire' request. At release, all the resources allocated to the VF are reclaimed. The release flow applies the close flow if applicable. Note that there are actually two types of release: 1. The VF has been removed, and so issued a 'release' request over the VF <-> PF Channel. 2. The PF is going down and so has to release all of it's VFs. Signed-off-by: Ariel Elior <ariele@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

2013-01-02bnx2x: Support of PF driver of a VF close requestAriel Elior
The 'close' command is the opposite of an init request. Here the queues of the VF are closed (if any are opened) and released. This flow applies the 'q_teardown' flow on all the queues. The VF state is changed by this request. Interrupts are disabled for the VF when closed.

2013-01-02bnx2x: Support statistics collection for VFs by the PFAriel Elior
Statistics are collected by the PF driver. The collection is performed via a query sent to the device which is basically an array of 3-tuples of the form (statistics client, function, DMAE address). In this patch the PF driver adds to the query, on top of the statistics clients it is maintaining for itself (rss queues, storage, etc), the 3-tuples for the VFs it is maintaining. The addresses used are the GPAs of the statistics buffers supplied by the VF in the init message on the VF <-> PF channel. The function parameter ensures that the iommu will translate the GPA to the correct physical address.

2013-01-02bnx2x: Support of PF driver of a VF init requestAriel Elior
The VF driver will send an 'init' request as part of its nic load flow. This message is used by the VF to publish the GPA's of its status blocks, slow path ring and statistics buffer. The PF driver notes all this down in the VF database, and also uses this message to transfer the VF to VF_INIT state internally.

2013-01-02bnx2x: Support of PF driver of a VF acquire requestAriel Elior
When a VF is probed by the VF driver, the VF driver sends an 'acquire' request over the VF <-> PF channel for the resources it needs to operate (interrupts, queues, etc). The PF driver either ratifies the request and allocates the resources, responds with the maximum values it will allow the VF to acquire, or fails the request entirely if there is a problem.

2013-01-02bnx2x: Infrastructure for VF <-> PF request on PF sideAriel Elior
Support interrupt from device which indicates VF has placed A request on the VF <-> PF channel. The PF driver issues a DMAE to retrieve the request from the VM memory (the Ghost Physical Address of the request is contained in the interrupt. The PF driver uses the GPA in the DMAE request, which is translated by the IOMMU to the correct physical address). The request which arrives is examined to recognize the sending VF. The PF driver allocates a workitem to handle the VF Operation (vfop). Signed-off-by: Ariel Elior <ariele@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

2013-01-02bnx2x: Allocate VF database in PF when VFs are presentAriel Elior
When A PF determines that it may have to manage SRIOV VFs it allocates a database for this purpose. The database is intended to keep track of the VF state, the resources allocated for each VF (queues, interrupt vectors, etc), the state of the VF's queues. When the VF loads the database is updated accordingly. When A VF closes the database is consulted to determine which resources need to be released (close queues against device, reclaim interrupt vectors, etc).

2013-01-02bnx2x: Support ndo_set_rxmode in VF driverAriel Elior
The VF driver uses the 'q_filter' request in the VF <-> PF channel to have the PF configure the requested rxmode to device. ndo_set_rxmode is called under bottom half lock, so sleeping until the response arrives over the VF <-> PF channel is out of the question. For this reason the VF driver returns from the ndo after scheduling a work item, which in turn processes the rx mode request and adds the classification information through the VF <-> PF channel accordingly.

Generally, the VF driver cannot access the chip, except by the narrow window its BAR allows. Care had to be taken so the VF driver will not reach code which accesses the chip elsewhere.
