| | | | | | | | | | | | | | | | This patch adds in the ecore 2 new personalities in addition to QED_PCI_ETH - QED_PCI_ISCSI and QED_PCI_ETH_ROCE. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | qed: Utilize FW 8.10.3.0Yuval Mintz2016-06-021-11/+11
|/ | | | | | | | | | | | | | | The New QED firmware contains several fixes, including: - Wrong classification of packets in 4-port devices. - Anti-spoof interoperability with encapsulated packets. - Tx-switching of encapsulated packets. It also slightly improves Tx performance of the device. In addition, this firmware contains the necessary logic for supporting iscsi & rdma, for which we plan on pushing protocol drivers in the imminent future.

* qed: VFs gracefully accept lack of PMYuval Mintz2016-05-161-1/+1

* qed*: Tx-switching configurationYuval Mintz2016-05-121-0/+1
| | | | | | | | | Device should be configured by default to VEB once VFs are active. This changes the configuration of both PFs' and VFs' vports into enabling tx-switching once sriov is enabled. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* qed: Bulletin and LinkYuval Mintz2016-05-121-3/+9
| | | | | | | | | | | | | | | | | | | Up to this point, VF and PF communication always originates from VF. As a result, VF cannot be notified of any async changes, and specifically cannot be informed of the current link state. This introduces the bulletin board, the mechanism through which the PF is going to communicate async notifications back to the VF. basically, it's a well-defined structure agreed by both PF and VF which the VF would continuously poll and into which the PF would DMA messages when needed. [Bulletin board is actually allocated and communicated in previous patches but never before used] Based on the bulletin infrastructure, the VF can query its link status and receive said async carrier changes.

* qed: IOV configure and FLRYuval Mintz2016-05-121-0/+1
| | | | | | | | | | | | | While previous patches have already added the necessary logic to probe VFs as well as enabling them in the HW, this patch adds the ability to support VF FLR & SRIOV disable. It then wraps both flows together into the first IOV callback to be provided to the protocol driver - `configure'. This would later to be used to enable and disable SRIOV in the adapter.

* qed: Introduce VFsYuval Mintz2016-05-121-61/+131
| | | | | | | | | | | | | | | | | This adds the qed VFs for the first time - The vfs are limited functions, with a very different PCI bar structure [when compared with PFs] to better impose the related security demands associated with them. This patch includes the logic neccesary to allow VFs to successfully probe [without actually adding the ability to enable iov]. This includes diverging all the flows that would occur as part of the pci probe of the driver, preventing VF from accessing registers/memories it can't and instead utilize the VF->PF channel to query the PF for needed information.

* qed: Add VF->PF channel infrastructureYuval Mintz2016-05-121-1/+9
| | | | | | | | | | | | | | | | | | | | | Communication between VF and PF is based on a dedicated HW channel; VF will prepare a messge, and by signaling the HW the PF would get a notification of that message existance. The PF would then copy the message, process it and DMA an answer back to the VF as a response. The messages themselves are TLV-based - allowing easier backward/forward compatibility. This patch adds the infrastructure of the channel on the PF side - starting with the arrival of the notification and ending with DMAing the response back to the VF. It also adds a dummy-response as reference, as it only lays the groundwork of the communication; it doesn't really add support of any actual messages.

* qed*: Conditions for changing linkYuval Mintz2016-04-251-0/+6
| | | | | | | | | | | | | | | | | There's some inconsistency in current logic determining whether the link settings of a given interface can be changed; I.e., in all modes other than the so-called `deault' mode the interfaces are forbidden from changing the configuration - but even this rule is not applied to all user APIs that may change the configuration. Instead, let the core-module [qed] decide whether an interface can change the configuration by supporting a new API function. We also revise the current rule, allowing all interfaces to change their configurations while laying the infrastructure for future modes where an interface would be blocked from making such a configuration.

| * qed: Correct slowpath interrupt schemeSudarsana Kalluru2015-12-071-38/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using INTa, ISR might be called before device is configured for INTa [E.g., due to other device asserting the shared interrupt line], in which case the ISR would read the SISR registers that shouldn't be read unless HW is already configured for INTa. This might break interrupts later on. There's also an MSI-X issue due to this difference, although it's mostly theoretical. This patch changes the initialization order, calling request_irq() for the slowpath interrupt only after the chip is configured for working in the preferred interrupt mode.

* qed: Add module with basic common supportYuval Mintz2015-10-271-0/+948
The Qlogic Everest Driver is the backend module for the QL4xxx ethernet products by Qlogic. This module serves two main purposes: 1. It's responsible to contain all the common code that will be shared between the various drivers that would be used with said line of products. Flows such as chip initialization and de-initialization fall under this category. 2. It would abstract the protocol-specific HW & FW components, allowing the protocol drivers to have a clean APIs which is detached in its slowpath configuration from the actual HSI. This adds a very basic module without any protocol-specific bits. I.e., this adds a basic implementation that almost entirely falls under the first category.
