2024-01-04r8169: fix building with CONFIG_LEDS_CLASS=mHeiner Kallweit3-7/+11
When r8169 is built-in but LED support is a loadable module, the new code to drive the LED causes a link failure: ld: drivers/net/ethernet/realtek/r8169_leds.o: in function `rtl8168_init_leds': r8169_leds.c:(.text+0x36c): undefined reference to `devm_led_classdev_register_ext' LED support is an optional feature, so fix this issue by adding a Kconfig symbol R8169_LEDS that is guaranteed to be false if r8169 is built-in and LED core support is a module. As a positive side effect of this change r8169_leds.o no longer is built under this configuration.

2024-01-04Revert "platform/x86: p2sb: Allow p2sb_bar() calls during PCI device probe"Shin'ichiro Kawasaki1-131/+41
This reverts commit b28ff7a7c3245d7f62acc20f15b4361292fe4117. The commit introduced P2SB device scan and resource cache during the boot process to avoid deadlock. But it caused detection failure of IDE controllers on old systems [1]. The IDE controllers on old systems and P2SB devices on newer systems have same PCI DEVFN. It is suspected the confusion between those two is the failure cause. Revert the change at this moment until the proper solution gets ready.

Luiz Angelo Daros de Luca reports that the MDIO bus code maintains a reference to the DT node, but does not hold a refcount on the node. The simple solution to this is to add the necessary refcounting into the MDIO bus code for all users, ensuring that on registration, the refcount is incremented, and only dropped when the MDIO bus is released. Do this for fwnodes, so we not only fix this for DT, but also other types of firmware nodes as well.

CSR.OPS bits specify the current operating mode and (according to documentation) they are updated by HW when the operating mode change request is processed. To comply with this check CSR.OPS before proceeding. Commit introduces ravb_set_opmode() that does all the necessities for setting the operating mode (set CCC.OPC (and CCC.GAC, CCC.CSEL, if any) and wait for CSR.OPS) and call it where needed. This should comply with all the HW manuals requirements as different manual variants specify that different modes need to be checked in CSR.OPS when setting CCC.OPC. If gPTP active in config mode is supported and it needs to be enabled, the CCC.GAC and CCC.CSEL needs to be configured along with CCC.OPC in the same write access. For this, ravb_set_opmode() allows passing GAC and CSEL as part of opmode and the function updates accordingly CCC register.

2024-01-04octeontx2-af: Re-enable MAC TX in otx2_stop processingNaveen Mamindlapalli3-1/+25
During QoS scheduling testing with multiple strict priority flows, the netdev tx watchdog timeout routine is invoked when a low priority QoS queue doesn't get a chance to transmit the packets because other high priority flows are completely subscribing the transmit link. The netdev tx watchdog timeout routine will stop MAC RX and TX functionality in otx2_stop() routine before cleanup of HW TX queues which results in SMQ flush errors because the packets belonging to low priority queues will never gets flushed since MAC TX is disabled. This patch fixes the issue by re-enabling MAC TX to ensure the packets in HW pipeline gets flushed properly.

Currently the NIX TX link credits are initialized based on the max frame size that can be transmitted on a link but when the MTU is changed, the NIX TX link credits are reprogrammed by the SW based on the new MTU value. Since SMQ max packet length is programmed to max frame size by default, there is a chance that NIX TX may stall while sending a max frame sized packet on the link with insufficient credits to send the packet all at once. This patch avoids stall issue by not changing the link credits dynamically when the MTU is changed.

2024-01-03net: ena: Take xdp packets stats into account in ena_get_stats64()David Arinzon1-3/+10

2024-01-03net: ena: Always register RX queue infoDavid Arinzon3-4/+13
The RX queue info contains information about the RX queue which might be relevant to the kernel. To avoid configuring this queue for different scenarios, this patch moves the RX queue configuration to ena_up()/ena_down() function and makes it configured every interface state toggle.

2024-01-03net: ena: Refactor napi functionsDavid Arinzon2-23/+30
This patch focuses on changes to the XDP part of the napi polling routine. 1. Update the `napi_comp` stat only when napi is actually complete. 2. Simplify the code by using a function pointer to the right napi routine (XDP vs non-XDP path) 3. Remove unnecessary local variables. 4. Adjust a debug print to show the processed XDP frame index rather than the pointer.

This check is already done in ena_clean_rx_irq() which indirectly calls it. This function is called in napi context and the driver doesn't allow to change the XDP program without performing destruction and reinitialization of napi context (part of ena_down/ena_up sequence).

2024-01-03net: ena: Use tx_ring instead of xdp_ring for XDP channel TXDavid Arinzon4-65/+61
When an XDP program is loaded the existing channels in the driver split into two halves: - The first half of the channels contain RX and TX rings, these queues are used for receiving traffic and sending packets originating from kernel. - The second half of the channels contain only a TX ring. These queues are used for sending packets that were redirected using XDP_TX or XDP_REDIRECT. Referring to the queues in the second half of the channels as "xdp_ring" can be confusing and may give the impression that ENA has the capability to generate an additional special queue. This patch ensures that the xdp_ring field is exclusively used to describe the XDP TX queue that a specific RX queue needs to utilize when forwarding packets with XDP TX and XDP REDIRECT, preserving the integrity of the xdp_ring field in ena_ring.

2024-01-03net: ena: Introduce total_tx_size field in ena_tx_buffer structDavid Arinzon2-2/+5
To avoid de-referencing skb or xdp_frame when we poll for TX completion (where they might not be in the cache), save the total TX packet size in the ena_tx_buffer object representing the packet. Also the 'print_once' field's type was changed from u32 to u8 to allow adding the 'total_tx_size' without changing the total size of the struct.

2024-01-03net: ena: Put orthogonal fields in ena_tx_buffer in a unionDavid Arinzon1-5/+7
The skb and xdpf pointers cannot be set together in the driver (each TX descriptor can send either an SKB or an XDP frame), and so it makes more sense to put them both in a union. This decreases the overall size of the ena_tx_buffer struct which improves cache locality.

2024-01-03net: ena: Pass ena_adapter instead of net_device to ena_xmit_common()David Arinzon4-11/+10
This change will enable the ability to use ena_xmit_common() in functions that don't have a net_device pointer. While it can be retrieved by dereferencing ena_adapter (adapter->netdev), there's no reason to do it in fast path code where this pointer is only needed for debug prints.

XDP system has a very large footprint in the driver's overall code. makes the whole driver's code much harder to read. Moving XDP code to dedicated files. This patch doesn't make any changes to the code itself and only cut-pastes the code into ena_xdp.c and ena_xdp.h files so the change is purely cosmetic.
