After transmission, the frame is returned on confirmation queues for cleanup. For this, store a backpointer to the xdp_frame in the private reserved area at the start of the TX buffer. No TX batching support is implemented at this time. Acked-by:

Use an xdp_frame structure for managing the frame. Store a backpointer to the structure at the start of the buffer before enqueueing for cleanup on TX confirmation. Reserve DPAA_TX_PRIV_DATA_SIZE bytes from the frame size shared with the XDP program for this purpose. Use the XDP API for freeing the buffer when it returns to the driver on the TX confirmation path. The frame queues are shared with the netstack. The DPAA driver is a LLTX driver so no explicit locking is required on transmission. This approach will be reused for XDP REDIRECT. Acked-by:

Implement the XDP_DROP and XDP_PASS actions. Avoid draining and reconfiguring the buffer pool at each XDP setup/teardown by increasing the frame headroom and reserving XDP_PACKET_HEADROOM bytes from the start. Since we always reserve an entire page per buffer, this change only impacts Jumbo frame scenarios where the maximum linear frame size is reduced by 256 bytes. Multi buffer Scatter/Gather frames are now used instead in these scenarios. Allow XDP programs to access the entire buffer. The data in the received frame's headroom can be overwritten by the XDP program. Extract the relevant fields from the headroom while they are still available, before running the XDP program. Since the headroom might be resized before the frame is passed up to the stack, remove the check for a fixed headroom value when building an skb. Allow the meta data to be updated and pass the information up the stack. Scatter/Gather frames are dropped when XDP is enabled. Acked-by:

Alex Elder says: ==================== net: ipa: start adding IPA v4.5 support This series starts updating the IPA code to support IPA hardware version 4.5. The first patch fixes a problem found while preparing these updates. Testing shows the code works with or without the change, and with the fix the code matches "downstream" Qualcomm code. The second patch updates the definitions for IPA register offsets and field masks to reflect the changes that come with IPA v4.5. A few register updates have been deferred until later, because making use of them involves some nontrivial code updates. One type of change that IPA v4.5 brings is expanding the range of certain configuration values. High-order bits are added in a few cases, and the third patch implements the code changes necessary to use those newly available bits. The fourth patch implements several fairly minor changes to the code required for IPA v4.5 support. The last two patches implement changes to the GSI registers used for IPA. Almost none of the registers change, but the range of memory in which most of the GSI registers is located is shifted by a fixed amount. The fifth patch updates the GSI register definitions, and the last patch implements the memory shift for IPA v4.5. ==================== Link: https://lore.kernel.org/r/20201125204522.5884-1-elder@linaro.orgSigned-off-by:

Alex Elder authored
The offsets for almost all GSI registers we use have different offsets starting at IPA version 4.5. Only two registers remain in their original location. In a way though, the new register locations are not *that* different. The entire group of affected registers has simply been shifted down in memory by a fixed amount (0xd000). So for example, the channel context 0 register that has a base offset of 0x0001c000 for "older" hardware now has a base offset of 0x0000f000. This patch aims to add support for IPA v4.5 registers at their new offets in a way that minimizes the amount of code that needs to change. It is not ideal, but it avoids the need to maintain a nearly complete set of additional register offset definitions. The approach takes advantage of the fact that when accessing GSI registers we do not access any of memory at lower end of the "gsi" memory range (with two exceptions already noted). In particular, we do not access anything within the bottom 0xd000 bytes of the GSI memory range. For IPA version 4.5, after we map the GSI memory, we adjust the virtual memory pointer downward by the fixed amount (0xd000). That way, register accesses using the offsets defined by the existing GSI_REG_*() macros will resolve to the proper locations for IPA version 4.5. The two registers *not* affected by this offset are accessed only in gsi_irq_setup(). There, for IPA version 4.5, we undo the general register adjustment by adding the fixed amount back to the virtual address to access these registers. Signed-off-by:

Very few GSI register definitions change for IPA v4.5, however as a group their position in memory shifts a constant amount (handled by the next commit). Add definitions and update comments to the set of GSI registers to support changes that come with IPA v4.5.

Update the IPA code to make use of the updated IPA v4.5 register definitions. Generally what this patch does is, if IPA v4.5 hardware is in use: - Ensure new registers or fields in IPA v4.5 are updated where required - Ensure registers or fields not supported in IPA v4.5 are not examined when read, or are set to 0 when written It does this while preserving the existing functionality for IPA versions lower than v4.5. The values to program for QSB_MAX_READS and QSB_MAX_WRITES and the source and destination resource counts are updated to be correct for all versions through v4.5 as well. Note that IPA_RESOURCE_GROUP_SRC_MAX and IPA_RESOURCE_GROUP_DST_MAX already reflect that 5 is an acceptable number of resources (which IPA v4.5 implements). Signed-off-by: -

IPA v4.5 adds a few fields to the endpoint header and extended header configuration registers that represent new high-order bits for certain offsets and sizes. Add code to incorporate these upper bits into the registers for IPA v4.5. This includes creating ipa_header_size_encoded(), which handles encoding the metadata offset field for use in the ENDP_INIT_HDR register in a way appropriate for the hardware version. This and ipa_metadata_offset_encoded() ensure the mask argument passed to u32_encode_bits() is constant. Signed-off-by:

Update "ipa_reg.h" so that register definitions support IPA hardware version 4.5, in addition to versions 3.5.1 through v4.2. Most of the register definitions are the same, but in some cases fields are added, changed, or eliminated. Updates for a few IPA v4.5 registers are more complex, and adding those definition will be deferred to separate patches. This patch only updates the register offset and field definitions, and adds informational comments. The only code change avoids accessing the backward compatibility register for IPA version 4.5 in ipa_hardware_config(). Other IPA v4.5-specific code changes will come later. Signed-off-by:

The 32-bit node number, aka node hash or node address, is calculated based on the 128-bit node identity when it is not set explicitly by the user. In future commits we will need to perform this hash operation on peer nodes while feeling safe that we obtain the same result. We do this by interpreting the initial hash as a network byte order number. Whenever we need to use the number locally on a node we must therefore translate it to host byte order to obtain an architecure independent result. Furthermore, given the context where we use this number, we must not allow it to be zero unless the node identity also is zero. Hence, in the rare cases when the xor-ed hash value may end up as zero we replace it with a fix number, knowing that the code anyway is capable of handling hash collisions. Acked-by:

This patch allows layer2 (LAPB) to react to netdev events itself and avoids the detour via layer3 (X.25). 1. Establish layer2 on NETDEV_UP events, if the carrier is already up. 2. Call lapb_disconnect_request() on NETDEV_GOING_DOWN events to signal the peer that the connection will go down. (Only when the carrier is up.) 3. When a NETDEV_DOWN event occur, clear all queues, enter state LAPB_STATE_0 and stop all timers. 4. The NETDEV_CHANGE event makes it possible to handle carrier loss and detection. In case of Carrier Loss, clear all queues, enter state LAPB_STATE_0 and stop all timers. In case of Carrier Detection, we start timer t1 on a DCE interface, and on a DTE interface we change to state LAPB_STATE_1 and start sending SABM(E). Signed-off-by:

1. Add / remove x25_link_device by NETDEV_REGISTER/UNREGISTER and also by NETDEV_POST_TYPE_CHANGE/NETDEV_PRE_TYPE_CHANGE. This change is needed so that the x25_neigh struct for an interface is already created when it shows up and is kept independently if the interface goes UP or DOWN. This is used in an upcomming commit, where x25 params of an neighbour will get configurable through ioctls. 2. NETDEV_CHANGE event makes it possible to handle carrier loss and detection. If carrier is lost, clean up everything related to this neighbour by calling x25_link_terminated(). 3. Also call x25_link_terminated() for NETDEV_DOWN events and remove the call to x25_clear_forward_by_dev() in x25_route_device_down(), as this is already called by x25_kill_by_neigh() which gets called by x25_link_terminated(). 4. Do nothing for NETDEV_UP and NETDEV_GOING_DOWN events, as these will be handled in layer 2 (LAPB) and layer3 (X.25) will be informed by layer2 when layer2 link is established and layer3 link should be initiated.

Ido Schimmel says: ==================== mlxsw: Update adjacency index more efficiently The device supports an operation that allows the driver to issue one request to update the adjacency index for all the routes in a given virtual router (VR) from old index and size to new ones. This is useful in case the configuration of a certain nexthop group is updated and its adjacency index changes. Currently, the driver does not use this operation in an efficient manner. It iterates over all the routes using the nexthop group and issues an update request for the VR if it is not the same as the previous VR. Instead, this patch set tracks the VRs in which the nexthop group is used and issues one request for each VR. Example: 8k IPv6 routes were added in an alternating manner to two VRFs. All the routes are using the same nexthop object ('nhid 1').
