2019-05-23ice: Reorganize ice_vf structJesse Brandeburg
The ice_vf struct can be used hundreds of times in our driver so it pays to use less memory per struct. ice_vf prior to this commit: /* size: 112, cachelines: 2, members: 25 */ /* sum members: 101, holes: 4, sum holes: 8 */ /* bit holes: 2, sum bit holes: 11 bits */ /* padding: 3 */ /* last cacheline: 48 bytes */ ice_vf after this commit: /* size: 104, cachelines: 2, members: 25 */ /* sum members: 100, holes: 3, sum holes: 4 */ /* bit holes: 1, sum bit holes: 3 bits */ /* last cacheline: 40 bytes */ Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2019-05-23ice: Use bitfields when possibleJesse Brandeburg
We can use bit fields to store boolean values and when the bit fields are next to each other, the compiler will combine them (as long as the size holds enough).

2019-03-22ice: Fix issue reconfiguring VF queuesAkeem G Abodunrin
When VF requested for queues changes, we need to update LAN Tx queue with correct number of VF queue pairs and re-allocate VF resources based on this new requested number of queues, which is constraint within maximum queue supported per VF.

2018-10-03ice: Implement virtchnl commands for AVF supportAnirudh Venkataramanan
virtchnl is a protocol/interface specification that allows the Intel "Adaptive Virtual Function (AVF)" driver (iavf.ko) to work with more than one physical function driver. The AVF driver sends "virtchnl commands" (control plane only) to the PF driver over mailbox queues and the PF driver executes these commands and returns a result to the VF, again over mailbox. This patch adds AVF support for the ice PF driver by implementing the following virtchnl commands: VIRTCHNL_OP_VERSION VIRTCHNL_OP_GET_VF_RESOURCES VIRTCHNL_OP_RESET_VF VIRTCHNL_OP_ADD_ETH_ADDR VIRTCHNL_OP_DEL_ETH_ADDR VIRTCHNL_OP_CONFIG_VSI_QUEUES VIRTCHNL_OP_ENABLE_QUEUES VIRTCHNL_OP_DISABLE_QUEUES VIRTCHNL_OP_ADD_ETH_ADDR VIRTCHNL_OP_DEL_ETH_ADDR VIRTCHNL_OP_CONFIG_VSI_QUEUES VIRTCHNL_OP_ENABLE_QUEUES VIRTCHNL_OP_DISABLE_QUEUES VIRTCHNL_OP_REQUEST_QUEUES VIRTCHNL_OP_CONFIG_IRQ_MAP VIRTCHNL_OP_CONFIG_RSS_KEY VIRTCHNL_OP_CONFIG_RSS_LUT VIRTCHNL_OP_GET_STATS VIRTCHNL_OP_ADD_VLAN VIRTCHNL_OP_DEL_VLAN VIRTCHNL_OP_ENABLE_VLAN_STRIPPING VIRTCHNL_OP_DISABLE_VLAN_STRIPPING Signed-off-by: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2018-10-03ice: Add support for VF reset eventsAnirudh Venkataramanan
Post VF initialization, there are a couple of different ways in which a VF reset can be triggered. One is when the underlying PF itself goes through a reset and other is via a VFLR interrupt. ice_reset_vf introduced in this patch handles both these cases. Also introduced in this patch is a helper function ice_aq_send_msg_to_vf to send messages to VF over the mailbox queue. The PF uses this to send reset notifications to VFs.

2018-10-03ice: Add handler to configure SR-IOVAnirudh Venkataramanan
This patch implements parts of ice_sriov_configure and VF reset flow. To create virtual functions (VFs), the user sets a value in num_vfs through sysfs. This results in the kernel calling the handler for .sriov_configure which is ice_sriov_configure. VF setup first starts with a VF reset, followed by allocation of the VF VSI using ice_vf_vsi_setup. Once the VF setup is complete a state bit ICE_VF_STATE_INIT is set in the vf->states bitmap to indicate that the VF is ready to go. Also for VF reset to go into effect, it's necessary to issue a disable queue command (ice_aqc_opc_dis_txqs). So this patch updates multiple functions in the disable queue flow to take additional parameters that distinguish if queues are being disabled due to VF reset.
