The TCP/IP transition from TCP_LISTEN to TCP_SYN_RECV and some other
transitions are not traced with tcp_set_state tracepoint.
In order to trace the whole tcp lifespans, two helpers are introduced,

Link Up and Down methods are used to change NTB link settings on
local side only for multi-port devices. Link is considered up
only if both sides local and peer set it up. Intel/AMD hardware
acts a bit different by assigning the Primary and Secondary roles,
so Primary device only is able to change

ntb_perf driver has been also updated so to have the multi-port
interface support. User now must specify what peer port is going
to be used to perform the test.

Since Switchtec patch there has been a new topology added to
the NTB API. It's called NTB_TOPO_SWITCH and dedicated for
PCIe switch chips. Even though topo field isn't used within the
IDT driver much, lets set it for the sake of unification.

Messages NTB API is now available. ntb_tool driver has been altered
to perform messages send and receive operation. The test of messages
read/write to/from peer device has been added to the script.

Simple (1 << pidx) operation causes undefined behaviour when
pidx >= 32. It must be casted to u64 to match the actual return
value of ntb_link_is_up() method, so to have all the possible
peer indexes covered and to get rid of undefined behaviour.
Additionally there are special macros in "linux/bito
There are devices (like IDT PCIe switches), which outbound MWs xlat address
is setup on peer side. In this case local side is supposed to allocate
a memory buffer and somehow deliver the xlat DMA address to peer so one
could set the outbound MW up. The MW test is altered so to support both

The multi-port NTB API was introduced in kernel 4.13 as well as the
first driver for the true multi-port devices of IDT PCIe-switches
series. But the test drivers still were left almost unchanged. Yes,
they didn't fail being used with new NTB API, but they only worked
with two-ports NTB devices. Th
The dma_mask and dma_coherent_mask fields of the NTB struct device
weren't initialized in hardware drivers. In fact it should be done
instead of PCIe interface usage, since NTB clients are supposed to
use NTB API and left unaware of real hardware implementation.
In addition to that ntb_device_regis

We have a use case in the at24 EEPROM driver (recently converted to
using regmap instead of raw i2c/smbus calls) where we read from/write
to the regmap in a loop, while protecting the entire loop with
a mutex.
Currently this implicitly makes us use two mutexes - one in the driver
and one in regmap
Benjamin,
The patch is fine for me:

In devm_of_phy_provider_register, the previously enabled clock rphy->clk
is now disabled, if devm_of_phy_provider_register() failed.
