Currently, user gets tc schedule info by implementing debugfs command "echo dump tc > cmd", this command will dump info in dmesg. It's unnecessary and heavy. To optimize it, create a single file "tc_sch_info" and use cat command to get info. It will return info to userspace, rather than record in dmesg. The display style is below: $ cat tc_sch_info enabled tc number: 4 weight_offset: 14 TC MODE WEIGHT 0 dwrr 25 1 dwrr 25 2 dwrr 25 3 dwrr 25 4 dwrr 0 5 dwrr 0 6 dwrr 0 7 dwrr 0 Signed-off-by:

Currently, user gets some tm info by implementing debugfs command "echo dump tm > cmd", this command will dump info in dmesg. It's unnecessary and heavy. In addition, the info of this command mixes info of qset, priority, pg and port. Qset and priority have their own command to get info of themself, so can remove info of qset and priority from this command. To optimize it, create two new files "tm_pg", "tm_port" in tm directory and use cat command to separately get info of pg and port. The display style is below: $ cat tm_pg ID PRI_MAP MODE DWRR C_IR_B C_IR_U C_IR_S C_BS_B C_BS_S ... 00 0x1f dwrr 1 75 9 0 31 20 ... $ cat tm_port IR_B IR_U IR_S BS_B BS_S FLAG RATE(Mbps) 75 9 0 31 20 1 200000 Signed-off-by:

Currently, the debugfs command for tm map is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "tm_map" for it, and query it by command "cat tm_map", return the result to userspace, rather than record in dmesg. As user can't specify queue id in cat command, driver will return info of all queue id. The display style is below: $ cat tm_map queue_id qset_id pri_id tc_id 0000 0000 00 00 INDEX | TM BP QSET MAPPING: 0000 | 00000000:00000000:00000000:00000000:00000000:00000000:00000000 0256 | 00000000:00000000:00000000:00000000:00000000:00000002:00000000 0512 | 00000000:00000000:00000000:00000004:00000000:00000000:00000000 0768 | 00000000:00000008:00000000:00000000:00000000:00000000:00000000 Signed-off-by:

modern userspace applications, like OVN, can configure the TC datapath to "recirculate" packets several times. If more than 4 "recirculation" rules are configured, packets can be dropped by __tcf_classify(). Changing the maximum number of reclassifications (from 4 to 16) should be sufficient to prevent drops in most use cases, and guard against loops at the same time. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Add support for new multipath hash policies This patchset adds support for two new multipath hash policies in mlxsw. Patch #1 emits net events whenever the net.ipv{4,6}.fib_multipath_hash_fields sysctls are changed. This allows listeners to react to changes in the packet fields used for the computation of the multipath hash. Patches #2-#3 refactor the code in mlxsw that is responsible for the configuration of the multipath hash, so that it will be easier to extend for the two new policies. Patch #4 adds the register fields required to support the new policies. Patch #5-#7 add support for inner layer 3 and custom multipath hash policies. Tested using following forwarding selftests: * custom_multipath_hash.sh * gre_custom_multipath_hash.sh * gre_inner_v4_multipath.sh * gre_inner_v6_multipath.sh ==================== -

When this policy is set, the kernel uses the inner layer 3 fields for multipath hash computation and falls back to the outer fields if no encapsulation was encountered. This behavior is most likely influenced by the behavior of the flow dissector, which is used for the packet dissection. The Spectrum ASIC, however, cannot fallback to outer fields if inner fields are not available. This should not result in a discrepancy from the software data path because if several flows have matching inner fields, they will tend to have matching outer fields as well. Therefore, implement this policy by enabling both outer and inner layer 3 fields for the multipath hash computation. Signed-off-by:

Currently, the multipath hash configuration is written directly to the register payload. While this is OK for the two currently supported policies, it is going to be hard to follow when more policies and more packet fields are added. Instead, set the required headers and fields in a bitmap and then dump it to the register payload. Signed-off-by:

The code was written when only two multipath hash policies were present, so the if statement was sufficient. The next patch and future patches are going to add support for more policies, so move to a switch statement. Signed-off-by:

In-kernel notifications are already sent when the multipath hash policy itself changes, but not when the multipath hash fields change. Add these notifications, so that interested listeners (e.g., switch ASIC drivers) could perform the necessary configuration. Signed-off-by:

S3FWRN5 depends on a clock input ("XI" pin) to function properly. Depending on the hardware configuration this could be an always-on oscillator or some external clock that must be explicitly enabled. So far we assumed that the clock is always-on. Make the driver request an (optional) clock from the device tree and make sure the clock is running before starting S3FWRN5. Note: S3FWRN5 asserts "GPIO2" whenever it needs the clock input to function correctly. On some hardware configurations, GPIO2 is connected directly to an input pin of the external clock provider (e.g. the main PMIC of the SoC). In that case, it can automatically AND the clock enable bit and clock request from S3FWRN5 so that the clock is actually only enabled when needed. It is also conceivable that on some other hardware configuration S3FWRN5's GPIO2 might be connected as a regular GPIO input of the SoC. In that case, follow-up patches could extend the driver to request the GPIO, set up an interrupt and only enable the clock when requested by S3FWRN5.
