Eric Dumazet says: ==================== net: use less storage for most sysctl This patch series adds a new sysctl type, to allow using u8 instead of "int" or "long int" types. Then we convert mosts sysctls found in struct netns_ipv4 to shrink it by three cache lines. ==================== Signed-off-by: -
Eric Dumazet authored
Many tcp sysctls are either bools or small ints that can fit into u8. Reducing space taken by sysctls can save few cache line misses when sending/receiving data while cpu caches are empty, for example after cpu idle period. This is hard to measure with typical network performance tests, but after this patch, struct netns_ipv4 has shrunk by three cache lines. Signed-off-by:

Networking has many sysctls that could fit in one u8. This patch adds proc_dou8vec_minmax() for this purpose. Note that the .extra1 and .extra2 fields are pointing to integers, because it makes conversions easier. Signed-off-by:

Voon Weifeng says: ==================== net: stmmac: enable multi-vector MSI This patchset adds support for multi MSI interrupts in addition to current single common interrupt implementation. Each MSI interrupt is tied to a newly introduce interrupt service routine(ISR). Hence, each interrupt will only go through the corresponding ISR. In order to increase the efficiency, enabling multi MSI interrupt will automatically select the interrupt mode configuration INTM=1. When INTM=1, the TX/RX transfer complete signal will only asserted on corresponding sbd_perch_tx_intr_o[] or sbd_perch_rx_intr_o[] without asserting signal on the common sbd_intr_o. Hence, for each TX/RX interrupts, only the corresponding ISR will be triggered. Every vendor might have different MSI vector assignment. So, this patchset only includes multi-vector MSI assignment for Intel platform. Changes: v1 -> v2 patch 2/5 -Remove defensive check for invalid dev pointer ==================== Signed-off-by: -
Wong, Vee Khee authored
For interrupt mode INTM=0, TX/RX transfer complete will trigger signal not only on sbd_perch_[tx|rx]_intr_o (Transmit/Receive Per Channel) but also on the sbd_intr_o (Common). As for multi-MSI implementation, setting interrupt mode INTM=1 is more efficient as each TX intr and RX intr (TI/RI) will be handled by TX/RX ISR without the need of calling the common MAC ISR. Updated the TX/RX NORMAL interrupts status checking process as the NIS status bit is not asserted for any RI/TI events for INTM=1. Signed-off-by:

If it fails, then it will automatically fallback to request allocation for single interrupts. Signed-off-by:

Now we introduce MSI interrupt service routines and hook these routines up if stmmac_open() sees valid irq line being requested:- stmmac_mac_interrupt() :- MAC (dev->irq), WOL (wol_irq), LPI (lpi_irq) stmmac_safety_interrupt() :- Safety Feat Correctible Error (sfty_ce_irq) & Uncorrectible Error (sfty_ue_irq) stmmac_msi_intr_rx() :- For all RX MSI irq (rx_irq) stmmac_msi_intr_tx() :- For all TX MSI irq (tx_irq) Each of IRQs will have its unique name so that we can differentiate them easily under /proc/interrupts.

In preparation to make stmmac support multi-vector MSI, we introduce the interrupt status masking according to RX, TX or RXTX. Default to use RXTX inside stmmac_dma_interrupt(), so there is no run-time logic difference now. Signed-off-by:

netdev_unregister_timeout_secs=0 can lead to printing the "waiting for dev to become free" message every jiffy. This is too frequent and unnecessary. Set the min value to 1 second. Also fix the merge issue introduced by "net: make unregister netdev warning timeout configurable": it changed "refcnt != 1" to "refcnt". Signed-off-by:

Alex Elder says: ==================== net: ipa: update registers for other versions This series updates IPA and GSI register definitions to permit more versions of IPA hardware to be supported. Most of the updates are informational, updating comments to indicate which IPA versions support each register and field. But some registers are new and others are deprecated. In a few cases register fields are laid out differently, and in these cases the changes are a little more substantive. I won't claim the result is 100% correct, but it's close, and should allow all IPA versions 3.x through 4.x to be supported by the driver. ==================== Signed-off-by: -

IPA v4.5 (GSI v2.5) supports a larger set of channel protocols, and adds an additional field to hold the most-significant bits of the protocol identifier on a channel. Add an inline function that encodes the protocol (including the extra bits for newer versions of IPA), and define some additional protocols. At this point we still use only GPI protocol.

Each GSI channel has a CNTXT_1 register that encodes the size of its ring buffer. The size of the field that records that is increased starting at IPA v4.9. Replace the use of a fixed-size field mask with a new inline function that encodes that size value. Similarly, the size of GSI event rings can be larger starting with IPA v4.9, so create a function to encode that as well. Signed-off-by:

The main purpose of this is to extend these GSI register definitions to support additional IPA versions. This patch makes some minor updates to "gsi_reg.h": - Define a DB_IN_BYTES field in the channel QOS register - Add some comments clarifying when certain fields are valid - Add the definition of GSI_CH_DB_STOP channel command - Add a couple of blank lines - Move one comment and indent another - Delete two unused register definitions at the end.

IPA version 4.9 and later use a different layout of some fields found in the COMP_CFG register. Define arbitration_lock_disable_encoded(), and use it to encode a value into the ATOMIC_FETCHER_ARB_LOCK_DIS field based on the IPA version. And define full_flush_rsc_closure_en_encoded() to encode a value into the FULL_FLUSH_WAIT_RSC_CLOSE_EN field based on the IPA version. The values of these fields are neither modified nor extracted by current code, but this patch makes this possible for all supported versions. Fix a mistaken comment above ipa_hardware_config_comp() intended to describe the purpose for the register. Signed-off-by:

Add and update IPA register definitions. Extend these definitions to incorporate a fairly small number of new symbols (register offsets and fields) to support IPA v3.0, v3.1, v3.5, v4.0, v4.1, v4.7, 4.9, and v4.11, and have the comments reflect when they are valid. None of the added symbols require changes elsewhere in the code. Update rsrc_grp_encoded() to support these other IPA versions. Add kerneldoc comments for the IPA IRQ numbers and sequencer type. Fix a few spots where the version check should be less restrictive (missed by an earlier patch). Signed-off-by:

Jakub Kicinski says: ==================== ethtool: clarify the ethtool FEC interface Our FEC configuration interface is one of the more confusing. It also lacks any error checking in the core. This certainly shows in the varying implementations across the drivers. Improve the documentation and add most basic checks. Sadly, it's probably too late now to try to enforce much more uniformity. Any thoughts & suggestions welcome. Next step is to add netlink for FEC, then stats. ==================== Signed-off-by: -
