sfc_ef100: Drop redundant pci_disable_pcie_error_reporting()

2023-03-09T07:34:39Z

51b35a454efd ("sfc: skeleton EF100 PF driver") added a call to pci_disable_pcie_error_reporting() in ef100_pci_remove(). Remove this call since there's no apparent reason to disable error reporting when it was not previously enabled. Note that since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core enables PCIe error reporting for all devices during enumeration, so the driver doesn't need to do it itself.

sfc: insert default MAE rules to connect VFs to representors

2022-07-30T04:22:06Z

Default rules are low-priority switching rules which the hardware uses in the absence of higher-priority rules. Each representor requires a corresponding rule matching traffic from its representee VF and delivering to the PF (where a check on INGRESS_MPORT in __ef100_rx_packet() will direct it to the representor). No rule is required in the reverse direction, because representor TX uses a TX override descriptor to bypass the MAE and deliver directly to the VF. Since inserting any rule into the MAE disables the firmware's own default rules, also insert a pair of rules to connect the PF to the physical network port and vice-versa.

sfc: Separate netdev probe/remove from PCI probe/remove

2022-06-29T12:40:47Z

The netdev probe will be used when moving from vDPA to EF100 BAR config. The netdev remove will be used when moving from EF100 to vDPA BAR config. In the process, change several log messages to pci_ instead of netif_ to remove the "(unregistered net_device)" text.

sfc: Separate efx_nic memory from net_device memory

2022-06-29T12:40:47Z

As we have a lot of common code this applies to all NIC architectures. Signed-off-by: Jonathan Cooper Co-developed-by: Martin Habets Signed-off-by: Martin Habets Signed-off-by: David S. Miller

sfc: Encapsulate access to netdev_priv()

2022-06-29T12:40:47Z

Once we separate struct efx_nic memory from net_device memory the existing usage will have to change. Apart from the new function efx_netdev_priv() accesses have been changed using: sed -i 's/netdev_priv/efx_netdev_priv/' Signed-off-by: Jonathan Cooper Co-developed-by: Martin Habets Signed-off-by: Martin Habets Signed-off-by: David S.

sfc: Remove netdev init from efx_init_struct

2022-06-29T12:40:46Z

Move functionality involving the struct net_device out of efx_init_struct so that we can initialise without a net dev for VDPA operation. Signed-off-by: Jonathan Cooper Co-developed-by: Martin Habets Signed-off-by: Martin Habets Signed-off-by: David S. Miller

sfc: add EF100 VF support via a write to sriov_numvfs

2022-04-30T01:43:01Z

This patch extends the EF100 PF driver by adding .sriov_configure() which would allow users to enable and disable virtual functions using the sriov sysfs.

sfc: Fix error code in probe

2020-09-21T20:55:13Z

This failure path should return a negative error code but it currently returns success. Fixes: 51b35a454efd ("sfc: skeleton EF100 PF driver") Signed-off-by: Dan Carpenter Acked-by: Edward Cree Signed-off-by: David S. Miller

sfc: fix build warnings on 32-bit

2020-08-20T19:00:16Z

Truncation of DMA_BIT_MASK to 32-bit dma_addr_t is semantically safe, but the compiler was warning because it was happening implicitly. Insert explicit casts to suppress the warnings.

sfc_ef100: add nic-type for VFs, and bind to them

We don't yet have a .sriov_configure() to create them, though. Signed-off-by: Edward Cree Signed-off-by: David S. Miller
