Timestamps are currently communicated to user space as 'struct timespec', which is not considered y2038 safe since it uses a 32-bit signed value for seconds. Fix this while the API is still not part of any official kernel release by using 64-bit nanoseconds timestamps instead.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2019-08-22 This series contains updates to i40e driver only. Arnd Bergmann reduces the stack usage which was causing warnings on 32-bit architectures due to large structure sizes for 2 functions getting inlined, so use noinline_for_stack to prevent the compilers from combining the 2 functions. Mauro S. M. Rodrigues fixes an issue when reading an EEPROM from SFP modules that comply with SFF-8472 but do not implement the Digital Diagnostic Monitoring (DDM) interface for i40e. Huhai found we were not checking the return value for configuring the transmit ring and continuing with XDP configuration of the transmit ring. Beilei fixes an issue of shifting signed 32-bit integers. Sylwia adds support for "packet drop mode" to the MAC configuration for admin queue command. This bit controls the behavior when a no-drop packet is blocking a TC queue. Adds support for persistent LLDP by checking the LLDP flag and reading the LLDP from the NVM when enabled. Adrian fixes the "recovery mode" check to take into account which device we are on, since x710 devices have 4 register values to check for status and x722 devices only have 2 register values to check. Piotr Azarewicz bumps the supported firmware API version to 1.9 which extends the PHY access admin queue command support. Jake makes sure the traffic class stats for a VEB are reset when the VEB stats are reset. Slawomir fixes a NULL pointer dereference where the VSI pointer was not updated before passing it to the i40e_set_vf_mac() when the VF is in a reset state, so wait for the reset to complete. Grzegorz removes the i40e_update_dcb_config() which was not using the correct NVM reads, so call i40e_init_dcb() in its place to correctly update the DCB configuration. Piotr Kwapulinski expands the scope of i40e_set_mac_type() since this is needed during probe to determine if we are in recovery mode. Fixed the driver reset path when in recovery mode. Marcin fixed an issue where we were breaking out of a loop too early when trying to get the PHY capabilities. v2: Combined patch 7 & 9 in the original series, since both patches bumped firmware API version. Also combined patches 12 & 13 in the original series, since one increased the scope of checking for MAC and the follow-on patch made use of function within the new scope. ==================== Signed-off-by: -

Driver waits after issuing a reset. When a reset takes too long a driver gives up. Implemented by invoking PF reset in a loop. After defined number of unsuccessful PF reset trials it returns error. Without this patch PF reset fails when NIC is in recovery mode. So make i40e_set_mac_type() public. i40e driver requires i40e_set_mac_type() to be public. It is required for recovery mode handling. Without this patch recovery mode could not be detected in i40e_probe(). Signed-off-by:

Add update to the VSI pointer passed to the i40e_set_vf_mac function. If VF is in reset state the driver waits in i40e_set_vf_mac function for the reset to be complete, yet after reset the vsi pointer that was passed into this function is no longer valid. The patch updates local VSI pointer directly from pf->vsi array, by using the id stored in VF pointer (lan_vsi_idx).

The functions i40e_aq_get_phy_abilities_resp() and i40e_set_fc() both have giant structure on the stack, which makes each one use stack frames larger than 500 bytes. As clang decides one function into the other, we get a warning for exceeding the frame size limit on 32-bit architectures: drivers/net/ethernet/intel/i40e/i40e_common.c:1654:23: error: stack frame size of 1116 bytes in function 'i40e_set_fc' [-Werror,-Wframe-larger-than=] When building with gcc, the inlining does not happen, but i40e_set_fc() calls i40e_aq_get_phy_abilities_resp() anyway, so they add up on the kernel stack just as much. The parts that actually use large stacks don't overlap, so make sure each one is a separate function, and mark them as noinline_for_stack to prevent the compilers from combining them again.

HV VHCA stats agent is responsible on running a preiodic rx/tx packets/bytes stats update. Currently the supported format is version MLX5_HV_VHCA_STATS_VERSION. Block ID 1 is dedicated for statistics data transfer from the VF to the PF. The reporter fetch the statistics data from all opened channels, fill it in a buffer and send it to mlx5_hv_vhca_write_agent. As the stats layer should include some metadata per block (sequence and offset), the HV VHCA layer shall modify the buffer before actually send it over block 1. Signed-off-by:

Control agent is responsible over of the control block (ID 0). It should update the PF via this block about every capability change. In addition, upon block 0 invalidate, it should activate all other supported agents with data requests from the PF. Upon agent create/destroy, the invalidate callback of the control agent is being called in order to update the PF driver about this change. The control agent is an integral part of HV VHCA and will be created and destroy as part of the HV VHCA init/cleanup flow. Signed-off-by:

Eran Ben Elisha authored
HV VHCA is a layer which provides PF to VF communication channel based on HyperV PCI config channel. It implements Mellanox's Inter VHCA control communication protocol. The protocol contains control block in order to pass messages between the PF and VF drivers, and data blocks in order to pass actual data. The infrastructure is agent based. Each agent will be responsible of contiguous buffer blocks in the VHCA config space. This infrastructure will bind agents to their blocks, and those agents can only access read/write the buffer blocks assigned to them. Each agent will provide three callbacks (control, invalidate, cleanup). Control will be invoked when block-0 is invalidated with a command that concerns this agent. Invalidate callback will be invoked if one of the blocks assigned to this agent was invalidated. Cleanup will be invoked before the agent is being freed in order to clean all of its open resources or deferred works. Block-0 serves as the control block. All execution commands from the PF will be written by the PF over this block. VF will ack on those by writing on block-0 as well. Its format is described by struct mlx5_hv_vhca_control_block layout.
