Once the chip goes through reset, the register mapping may be lost and any read of the mapped health registers may return garbage value until the registers are mapped again in the init path. Reading BNXT_FW_RESET_INPROG_REG after firmware reset will likely return garbage value due to the above reason. Reading this register is for information purpose only so remove it. Reviewed-by:

During ifup, if the driver detects that firmware has gone through a reset, it will go through a re-probe sequence. If the RDMA driver is loaded, the re-probe sequence includes calling the RDMA driver to stop. We need to set the BNXT_STATE_FW_RESET_DET flag earlier so that it is visible to the RDMA driver. The RDMA driver's stop sequence is different if firmware has gone through a reset. Reviewed-by:

The original intent here is to allow commands during reset to succeed without error when the device is disabled, to ensure that cleanup completes normally during NIC close, where firmware is not necessarily expected to respond. The problem with faking success during reset's PCI disablement is that unrelated ULP commands will also see inadvertent success during reset when failure would otherwise be appropriate. It is better to return a different error result such that reset related code can detect this unique condition and ignore as appropriate. Note, the pci_disable_device() when firmware is fatally wounded in bnxt_fw_reset_close() does not need to be addressed, as subsequent commands are already expected to fail due to the BNXT_NO_FW_ACCESS() check in bnxt_hwrm_do_send_msg().

In situations where FW has crashed, the bnxt_hwrm_do_send_msg() call will have to wait until timeout for each firmware message. This generally takes about half a second for each firmware message. If we try to unload the driver n this state, the unload sequence will take a long time to complete. Improve this by checking the health register if it is available and abort the wait for the firmware response if the register shows that firmware is not healthy. The very first message HWRM_VER_GET is excluded from this check because that message is used to poll for firmware to come out of reset during error recovery. Signed-off-by:

In order to read the firmware health status, we first need to determine the register location and then the register may need to be mapped. There are 2 code paths to do this. The first one is done early as a best effort attempt by the function bnxt_try_map_fw_health_reg(). The second one is done later in the function bnxt_map_fw_health_regs() after establishing communications with the firmware. We currently only set fw_health->status_reliable if we can successfully set up the health register in the first code path. Improve the scheme by setting the fw_health->status_reliable flag if either (or both) code paths can successfully set up the health register. This flag is relied upon during run-time when we need to check the health status. So this will make it work better. During ifdown, if the health register is mapped, we need to invalidate the health register mapping because a potential fw reset will reset the mapping. Similarly, we need to do the same after firmware reset during recovery. We'll remap it during ifup. Reviewed-by:

For DEVICE_VERSION_V3, the hardware supports to match specified data in the specified offset of packet payload. Each layer can have one offset, and can't be masked when configure flow director rule by ethtool command. The layer is selected based on the flow-type, ether for L2, ip4/ipv6 for L3, and tcp4/tcp6/udp4/udp6 for L4. For example, tcp4/tcp6/udp4/udp6 rules share the same user-def offset, but each rule can have its own user-def value. For the user-def field of ethtool -N/U command is 64 bits long. The bit 0~15 is used for user-def value, and bit 32~47 for user-def offset in HNS3 driver. Signed-off-by:

Currently, the flow director rule of aRFS is configured in the IO path. It's time-consuming. So move out the configuration, and configure it asynchronously. And keep ethtool and tc flower rule using synchronous way, otherwise the application maybe unable to know the rule is installed or pending. Add a state member for each flow director rule to indicate the rule state. There are 4 states: TO_ADD: the rule is waiting to add to hardware TO_DEL: the rule is waiting to remove from hardware DELETED: the rule has been removed from hardware. It's a middle state, used to remove the rule node in the fd_rule_list. ACTIVE: the rule is already added in hardware For asynchronous way, when receive a new request to add or delete flow director rule by aRFS, update the rule list, then request to schedule the service task to finish the configuration. For synchronous way, when receive a new request to add or delete flow director rule by ethtool or tc flower, configure hardware directly, then update the rule list if success. Signed-off-by:

Cristian Ciocaltea says: ==================== Add support for Actions Semi Owl Ethernet MAC This patch series adds support for the Ethernet MAC found on the Actions Semi Owl family of SoCs. For the moment I have only tested the driver on RoseapplePi SBC, which is based on the S500 SoC variant. It might work on S900 as well, but I cannot tell for sure since the S900 datasheet I currently have doesn't provide any information regarding the MAC registers - so I couldn't check the compatibility with S500. Similar story for S700: the datasheet I own is incomplete, but it seems the MAC is advertised with Gigabit capabilities. For that reason most probably we need to extend the current implementation in order to support this SoC variant as well. Please note that for testing the driver it is also necessary to update the S500 clock subsystem: https://lore.kernel.org/lkml/cover.1615221459.git.cristian.ciocaltea@gmail.com/ The DTS changes for the S500 SBCs will be provided separately. Thanks, Cristi Changes in v3: - Dropped the 'debug' module parameter and passed the default NETIF_MSG flags to netif_msg_init(), according to David's review - Removed the owl_emac_generate_mac_addr() function and the related OWL_EMAC_GEN_ADDR_SYS_SN config option until a portable solution to get the system serial number is found - when building on arm64 the following error is thrown (as reported by Rob's kernel bot): '[...]/owl-emac.c:9:10: fatal error: asm/system_info.h: No such file or directory' - Rebased patchset on v5.12-rc4 Changes in v2: * According to Philipp's review - Requested exclusive control over serial line via devm_reset_control_get_exclusive() - Optimized error handling by using dev_err_probe() * According to Andrew's review - Dropped the inline keywords - Applied Reverse Christmas Tree format to local variable declarations - Renamed owl_emac_phy_config() to owl_emac_update_link_state() - Documented the purpose of the special descriptor used in the context of owl_emac_setup_frame_xmit() - Updated comment inside owl_emac_mdio_clock_enable() regarding the MDC clock divider setup - Indicated MAC support for symmetric pause via phy_set_sym_pause() in owl_emac_phy_init() - Changed the MAC addr generation algorithm in owl_emac_generate_mac_addr() by setting the locally administered bit in byte 0 and replacing bytes 1 & 2 with additional entries from enc_sn - Moved devm_add_action_or_reset() before clk_set_rate() in owl_emac_probe() * Other - Added SMII interface support: updated owl_emac_core_sw_reset(), added owl_emac_clk_set_rate(), updated description in the YAML binding - Changed OWL_EMAC_TX_TIMEOUT from 0.05*HZ to 2*HZ ==================== Signed-off-by:

Add a function to set the dynamic queue limit minimum value. Some specific drivers might have legitimate reasons to configure dql.min_limit to a given value. Typically, this is the case when the PDU of the protocol is smaller than the packet size to used to carry those frames to the device. Concrete example: a CAN (Control Area Network) device with an USB 2.0 interface. The PDU of classical CAN protocol are roughly 16 bytes but the USB packet size (which is used to carry the CAN frames to the device) might be up to 512 bytes. Wen small traffic burst occurs, BQL algorithm is not able to immediately adjust and this would result in having to send many small USB packets (i.e packet of 16 bytes for each CAN frame). Filling up the USB packet with CAN frames is relatively fast (small latency issue) but the gain of not having to send several small USB packets is huge (big throughput increase). In this case, forcing dql.min_limit to a given value that would allow to stuff the USB packet is always a win. This function is to be used by network drivers which are able to prove through a rationale and through empirical tests on several environment (with other applications, heavy context switching, virtualization...), that they constantly reach better performances with a specific predefined dql.min_limit value with no noticeable latency impact.

1. Remove CONFIG_HAVE_NET_DSA. CONFIG_HAVE_NET_DSA is a legacy leftover from the times when drivers should have selected CONFIG_NET_DSA manually. Currently, all drivers has explicit 'depends on NET_DSA', so this is no more needed. 2. CONFIG_HAVE_NET_DSA dependencies became CONFIG_NET_DSA's ones. - dropped !S390 dependency which was introduced to be sure NET_DSA can select CONFIG_PHYLIB. DSA migrated to Phylink almost 3 years ago and the PHY library itself doesn't depend on !S390 since commit 870a2b5e ("phylib: remove !S390 dependeny from Kconfig"); - INET dependency is kept to be sure we can select NET_SWITCHDEV; - NETDEVICES dependency is kept to be sure we can select PHYLINK. 3. DSA drivers menu now depends on NET_DSA. Instead on 'depends on NET_DSA' on every single driver, the entire menu now depends on it. This eliminates a lot of duplicated lines from Kconfig with no loss (when CONFIG_NET_DSA=m, drivers also can be only m or n). This also has a nice side effect that there's no more empty menu on configurations without DSA. 4. Kbuild will now descend into 'drivers/net/dsa' only when CONFIG_NET_DSA is y or m. This is safe since no objects inside this folder can be built without DSA core, as well as when CONFIG_NET_DSA=m, no objects can be built-in. Signed-off-by:

This reverts commit e9bf9694. The topic of the reverted patch is the support for switches with global VLAN filtering, added by commit 061f6a50 ("net: dsa: Add ndo_vlan_rx_{add, kill}_vid implementation"). Be there a switch with 4 ports swp0 -> swp3, and the following setup: ip link add br0 type bridge vlan_filtering 1 ip link set swp0 master br0 ip link set swp1 master br0 What would happen with VLAN-tagged traffic received on standalone ports swp2 and swp3? Well, it would get dropped, were it not for the .ndo_vlan_rx_add_vid and .ndo_vlan_rx_kill_vid implementations (called from vlan_vid_add and vlan_vid_del respectively). Basically, for DSA switches where VLAN filtering is a global attribute, we enforce the standalone ports to have 'rx-vlan-filter: off [fixed]' in their ethtool features, which lets the user know that all VLAN-tagged packets that are not explicitly added in the RX filtering list are dropped. As for the sja1105 driver, at the time of the reverted patch, it was operating in a pretty handicapped mode when it had ports under a bridge with vlan_filtering=1. Specifically, it was unable to terminate traffic through the CPU port (for further explanation see "Traffic support" in Documentation/networking/dsa/sja1105.rst). However, since then, the sja1105 driver has made considerable progress, and that limitation is no longer as severe now. Specifically, since commit 2cafa72e ("net: dsa: sja1105: add a new best_effort_vlan_filtering devlink parameter"), the driver is able to perform CPU termination even when some ports are under bridges with vlan_filtering=1. Then, since commit 8841f6e6 ("net: dsa: sja1105: make devlink property best_effort_vlan_filtering true by default"), this even became the default operating mode. So we can now take advantage of the logic in the DSA core. Signed-off-by:

With these in place, QSB settings are programmed from information found in the data files rather than being embedded in code. Support is then added for reprenting another QSB property (supported for IPA v4.0+). The third patch updates the definition of the sequencer type used for an endpoint. Previously a set of 2-byte symbols with fairly long names defined the sequencer type, but now those are broken into 1-byte halves whose names are a little more informative. The fourth patch moves the sequencer type definition so it only applies to TX endpoints (they aren't valid for RX endpoints).

We only program the sequencer type for TX endpoints. So move the definition of the sequencer type fields into the TX-specific portion of the endpoint configuration data. There's no need to maintain this in the IPA structure; we can extract it from the configuration data it points to in the one spot it's needed. We previously specified the sequencer type for RX endpoints with INVALID values. These are no longer needed, so get rid of them. Signed-off-by:

An IPA endpoint has a sequencer that must be configured based on how the endpoint is to be used. Currently the IPA code programs the sequencer type by splitting a value into four 4-bit nibbles. Doing that doesn't really add much value, and regardless, a better way of splitting the sequencer type is into two halves--the lower byte describing how normal packet processing is handled, and the next byte describing information about processing replicas. So split the sequencer type into two sub-parts: the sequencer type and the replication sequencer type. Define the values supported for the "main" sequencer type, and define the values supported for the replication part separately. In addition, the sequencer type names are quite verbose, encoding what the type includes, but also what it *excludes*. Rename the sequencer types in a way that mainly describes the number of passes that a packet takes through the IPA processing pipeline, and how many of those passes end by supplying the processed packet to the microprocessor. The result expands the supported types beyond what is required for now, but simplifies the way these are defined. Signed-off-by:
