2021-05-20net: hns3: refactor dump qos pause cfg of debugfsGuangbin Huang3-14/+25
Currently, user gets pause config by implementing debugfs command "echo dump qos pause cfg > cmd", this command will dump info in dmesg. It's unnecessary and heavy. To optimize it, create a single file "qos_pause_cfg" in tm directory and use cat command to get info. It will return info to userspace, rather than record in dmesg.

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.

2021-05-20igc: Enable TX via AF_XDP zero-copyAndre Guedes4-8/+129
Add support for transmitting packets via AF_XDP zero-copy mechanism. The packet transmission itself is implemented by igc_xdp_xmit_zc() which is called from igc_clean_tx_irq() when the ring has AF_XDP zero-copy enabled. Likewise i40e and ice drivers, the transmission budget used is the number of descriptors available on the ring. A new tx buffer type is introduced to 'enum igc_tx_buffer_type' to indicate the tx buffer uses memory from xsk pool so it can be properly cleaned after transmission or when the ring is cleaned. The I225 controller has only 4 Tx hardware queues so the main difference between igc and other Intel drivers that support AF_XDP zero-copy is that there is no tx ring dedicated exclusively to XDP. Instead, tx rings are shared between the network stack and XDP, and netdev queue lock is used to ensure mutual exclusion. This is the same approach implemented to support XDP_TX and XDP_REDIRECT actions.

2021-05-20igc: Enable RX via AF_XDP zero-copyAndre Guedes5-18/+449
Add support for receiving packets via AF_XDP zero-copy mechanism. Add a new flag to 'enum igc_ring_flags_t' to indicate the ring has AF_XDP zero-copy enabled so proper ring setup is carried out during ring configuration in igc_configure_rx_ring(). RX buffers can now be allocated via the shared pages mechanism (default behavior of the driver) or via xsk pool (when AF_XDP zero-copy is enabled) so a union is added to the 'struct igc_rx_buffer' to cover both cases. When AF_XDP zero-copy is enabled, rx buffers are allocated from the xsk pool using the new helper igc_alloc_rx_buffers_zc() which is the counterpart of igc_alloc_rx_buffers(). Likewise other Intel drivers that support AF_XDP zero-copy, in igc we have a dedicated path for cleaning up rx irqs when zero-copy is enabled. This avoids adding too many checks within igc_clean_rx_irq(), resulting in a more readable and efficient code since this function is called from the hot-path of the driver.

Up to this point, Tx buffers are associated with either a skb or a xdpf, and the IGC_TX_FLAGS_XDP flag was enough to distinguish between these two case. However, with upcoming patches that will add AF_XDP zero-copy support, a third case will be introduced so this flag-based approach won't fit well. In preparation to land AF_XDP zero-copy support, replace the IGC_TX_FLAGS_XDP flag by an enum which will be extended once zero-copy support is introduced to the driver.

Currently, xdp_rxq and memory model are both registered during RX resource setup time by igc_xdp_register_rxq_info() helper.

2021-05-20igc: Refactor __igc_xdp_run_prog()Andre Guedes1-28/+28
Refactor __igc_xdp_run_prog() helper from igc_xdp_run_prog(), preparing the code for AF_XDP zero-copy support which is added by upcoming patches. The existing igc_xdp_run_prog() caters to regular XDP rx path which has to verify if bpf_prog is not NULL. Zero-copy path assumes that bpf_prog is not NULL and hence this check is not required. Therefore it makes sense to refactor the common code into a helper function, to avoid code duplication.

2021-05-20clk: meson: g12a: fix gp0 and hifi rangesJerome Brunet1-1/+1
While some SoC samples are able to lock with a PLL factor of 55, others samples can't. ATM, a minimum of 60 appears to work on all the samples I have tried. Even with 60, it sometimes takes a long time for the PLL to eventually lock. The documentation says that the minimum rate of these PLLs DCO should be 3GHz, a factor of 125. Let's use that to be on the safe side. With factor range changed, the PLL seems to lock quickly (enough) so far. It is still unclear if the range was the only reason for the delay.
