| | | | | | | | | | | | | | | | | | Current code assumes that both host and device operates in Little Endian in lots of places. While this is true for x86 platform, this doesn't mean we should not care about this. This commit addresses all parts of the code that were pointed out by sparse checker. All operations with restricted (__be*/__le*) types are now protected with explicit from/to CPU conversions, even if they're noops on common setups. I'm sure there are more such places, but this implies a deeper code investigation, and is a subject for future works.

| | | | | | | | | | | | | | | | | This fixes a crash introduced by recent is_kdump_kernel() check. The source of the crash is that kdump kernel can be loaded on a system with already created VFs. But for such VFs, it will follow a logic path of PF and eventually crash. Thus, we are partially reverting back previous changes and instead use is_kdump_kernel is a single init point of PF init, where we disable SRIOV explicitly.

* qed: Use dmae to write to widebus registers in fw_funcsMichal Kalderon2020-01-271-5/+6
| | | | | | | | | | | | | | There are several wide-bus registers written to by the fw_funcs that require using the dmae for atomicity. Therefore using the dmae channel functionality was added to the fw_funcs file, since the code is very similar to the previously used code, the structures used were moved to qed_hsi. Due to FW conventions, the names of the flags in the struct changed. Since this required slight modification in the places that set the flags the code was modified to use GET/SET FIELD macros.

* qed* : Add new TLV to request PF to update MAC in bulletin boardShahed Shaikh2018-04-201-0/+37
| | | | | | | | | | | | | | | | | There may be a need for VF driver to request PF to explicitly update its bulletin with a MAC address. e.g. When user assigns a MAC address to VF while VF is still down, and PF's bulletin board contains different MAC address, in this case, when VF's interface is brought up, it gets loaded with MAC address from bulletin board which is not desirable. To handle this corner case, we need a new TLV to request PF to update its bulletin board with suggested MAC. This request will be honored only for trusted VFs.

| | | | | | | | | | | | | | As per existing behavior, when PF sets a MAC address for a VF (also called as forced MAC), VF is not allowed to change its MAC address afterwards. This puts the limitation on few use cases such as bonding of VFs, where bonding driver asks VF to change its MAC address. This patch uses a VF trust mode to allow VF to change its MAC address in spite PF has set a forced MAC for that VF. Signed-off-by: Shahed Shaikh <shahed.shaikh@cavium.com> Signed-off-by: David S.

* qed: QL41xxx VF MSI-x tableMintz, Yuval2017-05-301-1/+31
| | | | | | | | | | | | | | | The QL41xxx adapters' PCI allows a single configuration for the MSI-x table size of all child VFs of a given PF. The existing code wouldn't cause the management firmware to set that value, meaning the VFs would retain the default MSI-x table size. Introduce a new scheme so that whenever a VF is enabled, driver would set the number of MSI-x to be the maximum over the various VFs' needs.

* qed - VF tunnelling support [VXLAN/GENEVE/GRE]Chopra, Manish2017-04-251-0/+217
| | | | | | | | | | | | | | This patch adds hardware channel APIs support between VF and PF for tunnelling configuration for the VFs. According to that configuration VFs can run VXLAN/GENEVE/GRE tunnels over it with tunnel features offloaded. Using these APIs VF can also request for UDP ports configuration to the PF, although PF and it's child VFs share the same port.

| | | | | | | | | | | | The link information exists only on the leading hwfn, but some of its derivatives [e.g., min/max rate] need to be configured for each hwfn. When re-basing the VF link view, use the leading hwfn information as basis for all existing hwfns to allow said configurations to stick.

* qed: Deprecate VF multiple queue-stopMintz, Yuval2017-03-211-46/+58
| | | | | | | | | | | | | | The PF<->VF interface allows for the VF to request multiple queues closure via a single message, but this has never been used by any official driver. We now deprecate this option, forcing each queue close to arrive via a different command; This would be required for future TLVs that are going to extend the queue TLVs with additional information on a per-queue basis.
