| | * thunderbolt: Allow NVM upgrade of USB4 host routersSzuying Chen2022-09-071-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel pre-USB4 host routers required the firmware connection manager to be active in order to perform NVM firmware upgrade and for this reason it was disabled when software connection manager is active. However, this is not necessary for USB4 host routers as this functionality is part of router operations that the router implements if it wants to support this.

| | * thunderbolt: Add support for receiver lane marginingMika Westerberg2022-09-056-0/+1043
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB4 spec defines standard set of registers to be used for receiver lane margining. This is useful for I/O interface quality and electrical robustness validation during manufacturing. Expose receiver lane margining through new debugfs directory "margining" that is added under each connected USB4 port. Users can then run the margining by writing to the exposed attributes under that directory. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
| | * thunderbolt: Add helper to check if CL states are enabled on portMika Westerberg2022-09-053-0/+30
| | | | | | | | | | | | | | | | | | We will need this when enabling lane margining support. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
| | * thunderbolt: Pass CL state bitmask to tb_port_clx_supported()Mika Westerberg2022-09-053-13/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of testing just a single CL state we can pass a bitmask of states to check. This makes it simpler for callers of the function. We also add a check for CL2 even though not fully supported by the driver yet.

| | * thunderbolt: Move port CL state functions into correct place in switch.cMika Westerberg2022-09-051-106/+106
| | | | | | | | | | | | | | | | | | | | | They should be close to other functions dealing with USB4 ports. No functional impact. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

| | * thunderbolt: Add DP OUT resource when DP tunnel is discoveredSanjay R Mehta2022-08-151-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the boot firmware implements a connection manager of its own it may create a DisplayPort tunnel and will be handed off to Linux connection manager, but the DP OUT resource is not saved in the dp_resource list. This patch adds tunnelled DP OUT port to the dp_resource list once the DP tunnel is discovered.

This significantly improves TCP segment coalescing and simplifies deployments as different workloads benefit from HW or SW GRO. - Shrink the size of the base zero-copy send structure. - Move TCP init under a new slow / sleepable version of DO_ONCE(). BPF: - Add BPF-specific, any-context-safe memory allocator. - Add helpers/kfuncs for PKCS#7 signature verification from BPF programs. - Define a new map type and related helpers for user space -> kernel communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF). - Allow targeting BPF iterators to loop through resources of one task/thread. - Add ability to call selected destructive functions. Expose crash_kexec() to allow BPF to trigger a kernel dump. Use CAP_SYS_BOOT check on the loading process to judge permissions. - Enable BPF to collect custom hierarchical cgroup stats efficiently by integrating with the rstat framework. - Support struct arguments for trampoline based programs. Only structs with size <= 16B and x86 are supported. - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping sockets (instead of just TCP and UDP sockets). - Add a helper for accessing CLOCK_TAI for time sensitive network related programs. - Support accessing network tunnel metadata's flags. - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open. - Add support for writing to Netfilter's nf_conn:mark. Protocols: - WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation (MLO) work (802.11be, WiFi 7). - vsock: improve support for SO_RCVLOWAT. - SMC: support SO_REUSEPORT. - Netlink: define and document how to use netlink in a "modern" way. Support reporting missing attributes via extended ACK. - IPSec: support collect metadata mode for xfrm interfaces. - TCPv6: send consistent autoflowlabel in SYN_RECV state and RST packets. - TCP: introduce optional per-netns connection hash table to allow better isolation between namespaces (opt-in, at the cost of memory and cache pressure). - MPTCP: support TCP_FASTOPEN_CONNECT. - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior. - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets. - Open vSwitch: - Allow specifying ifindex of new interfaces. - Allow conntrack and metering in non-initial user namespace. - TLS: support the Korean ARIA-GCM crypto algorithm. - Remove DECnet support. Driver API: - Allow selecting the conduit interface used by each port in DSA switches, at runtime. - Ethernet Power Sourcing Equipment and Power Device support. - Add tc-taprio support for queueMaxSDU parameter, i.e. setting per traffic class max frame size for time-based packet schedules. - Support PHY rate matching - adapting between differing host-side and link-side speeds. - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode. - Validate OF (device tree) nodes for DSA shared ports; make phylink-related properties mandatory on DSA and CPU ports. Enforcing more uniformity should allow transitioning to phylink. - Require that flash component name used during update matches one of the components for which version is reported by info_get(). - Remove "weight" argument from driver-facing NAPI API as much as possible. It's one of those magic knobs which seemed like a good idea at the time but is too indirect to use in practice. - Support offload of TLS connections with 256 bit keys.

However, this time we only apply it for Falcon Ridge controllers as a form of an additional quirk. For non-Falcon Ridge this does nothing.

Accordingly, the parent field can be dropped from struct acpi_device and for this purpose define acpi_dev_parent() to retrieve a parent struct acpi_device pointer from the dev.parent field in struct acpi_device. Next, update all of the users of the parent field in struct acpi_device to use acpi_dev_parent() instead of it and drop it. While at it, drop the ACPI_IS_ROOT_DEVICE() macro that is only used in one place in a confusing way. No intentional functional impact. Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB4 Inter-Domain Service specification defines a protocol that can be used to establish lane bonding between two USB4 domains (hosts). So far we have not implemented it because the host controller DMA was not fast enough to be able to go over 20 Gbits/s even if lanes were bonded. However, starting from Intel Alder Lake CPUs the DMA can go over 20 Gbits/s so now it makes more sense to add this support to the driver. Because both ends need to negotiate the bonding we add a simple state machine that tracks the connection state and does the necessary steps described by the USB4 Inter-Domain Service specification. We only establish lane bonding when both sides of the link support it. Otherwise we default to use the single lane. Also this is only done when software connection manager is used. On systems with firmware based connection manager, it handles the high-speed tunneling so bonding lanes is specific to the implementation (Intel firmware based connection manager does not support lane bonding).

To support this split setting the link width and triggering the actual bonding a separate functions that can be called as needed. While there remove duplicated empty line in the kernel-doc comment of tb_port_lane_bonding_disable(). Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

| * thunderbolt: Use different lane for second DisplayPort tunnelMika Westerberg2022-04-194-17/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Brad reported that on Apple hardware with Light Ridge or Falcon Ridge controller, plugging in a chain of Thunderbolt displays (Light Ridge based controllers) causes all kinds of tearing and flickering. The reason for this is that on Thunderbolt 1 hardware there is no lane bonding so we have two independent 10 Gb/s lanes, and currently Linux tunnels both displays through the lane 1. This makes the displays to share the 10 Gb/s bandwidth which may not be enough for higher resolutions. For this reason make the second tunnel go through the lane 0 instead. This seems to match what the macOS connection manager is also doing.
