Merge "ARM: keystone: add TI SCI protocol support for v4.10" from
Tero Kristo:
[description taken from http://processors.wiki.ti.com/index.php/TISCI
Texas Instruments' Keystone generation System on Chips (SoC) starting
with 66AK2G02, now include a dedicated SoC System Control entity called
PMMC(Power Management Micro Controller) in line with ARM architecture
recommendations. The function of this module is to integrate all system
operations in a centralized location. Communication with the SoC System
Control entity from various processing units like ARM/DSP occurs over
Message Manager hardware block.
...
Texas Instruments' System Control Interface defines the communication
protocol between various processing entities to the System Control Entity
on TI SoCs. This is a set of message formats and sequence of operations
required to communicate and get system services processed from System
Control entity in the SoC.]

This patch modifies test_cgrp2_attach to use getopt so we can use standard
command line parsing.
It also adds an option to run the program in detach only mode. This does
not attach a new filter at the cgroup, but only runs the detach command.
Lastly, it changes the attach code to not detach and then attach. It relies
on the 'hotswap' behaviour of CGroup BPF programs to be able to change
in-place. If detach-then-attach behaviour needs to be tested, the example
can be run in detach only mode prior to attachment.

Add an IFLA_XDP_FLAGS attribute that can be passed for setting up
XDP along with IFLA_XDP_FD, which eventually allows user space to
implement typical add/replace/delete logic for programs. Right now,
calling into dev_change_xdp_fd() will always replace previous programs.
When passed XDP_FLAGS_UPDATE_IF_NOEXIST, we can handle this more
graceful when requested by returning -EBUSY in case we try to
attach a new program, but we find that another one is already
attached. This will be used by upcoming front-end for iproute2 as
well.

Broadcom BCM7xxx internal PHYs can leverage the Broadcom PHY library
module PHY error counters helper functions, just implement the
appropriate PHY driver function calls to do so. We need to allocate some
storage space for our PHY statistics, and provide it to the Broadcom PHY
library, so do this in a specific probe function, and slightly wrap the
get_stats function call.

Add support code to allow retrieving these error counters. Since the
Broadcom PHY library code is used by several drivers, make it possible
for them to specify the storage for the software copy of the statistics.

Rationale: The differences between Falcon and Siena are in many ways larger
than those between Siena and EF10 (despite Siena being nominally "Falcon-
architecture"); for instance, Falcon has no MCPU, so there is no MCDI.
Removing Falcon support from the sfc driver should simplify the latter,
and avoid the possibility of Falcon support being broken by changes to sfc
(which are rarely if ever tested on Falcon, it being end-of-lifed hardware).
The sfc-falcon driver created in this changeset is essentially a copy of the
sfc driver, but with Siena- and EF10-specific code, including MCDI, removed
and with the "efx_" identifier prefix changed to "ef4_" (for "EFX 4000-
series") to avoid collisions when both drivers are built-in.
This changeset removes Falcon from the sfc driver's PCI ID table; then in
sfc I've removed obvious Falcon-related code: I removed the Falcon NIC
functions, Falcon PHY code, and EFX_REV_FALCON_*, then fixed up everything
that referenced them.
Also, increment minor version of both drivers (to 4.1).
For now, CONFIG_SFC selects CONFIG_SFC_FALCON, so that updating old configs
doesn't cause Falcon support to disappear; but that should be undone at
some point in the future.

====================
tcp: sender chronographs instrumentation
This patch set provides instrumentation on TCP sender limitations.
While developing the BBR congestion control, we noticed that TCP
sending process is often limited by factors unrelated to congestion
control: insufficient sender buffer and/or insufficient receive
window/buffer to saturate the network bandwidth. Unfortunately these
limits are not visible to the users and often the poor performance
is attributed to the congestion control of choice.
Thie patch aims to help users get the high level understanding of
where sending process is limited by, similar to the TCP_INFO design.
It is not to replace detailed kernel tracing and instrumentation
facilities.
In addition this patch set provide a new option to the timestamping
work to instrument these limits on application data unit. For exampe,
one can use SO_TIMESTAMPING and this patch set to measure the how
long a particular HTTP response is limited by small receive window.
Patch set was initially written by Francis Yan then polished
by Yuchung Cheng, with lots of help from Eric Dumazet and Soheil
Hassas Yeganeh.

This patch exports the sender chronograph stats via the socket
SO_TIMESTAMPING channel. Currently we can instrument how long a
particular application unit of data was queued in TCP by tracking
SOF_TIMESTAMPING_TX_SOFTWARE and SOF_TIMESTAMPING_TX_SCHED. Having
these sender chronograph stats exported simultaneously along with
these timestamps allow further breaking down the various sender
limitation. For example, a video server can tell if a particular
chunk of video on a connection takes a long time to deliver because
TCP was experiencing small receive window. It is not possible to
tell before this patch without packet traces.
To prepare these stats, the user needs to set
SOF_TIMESTAMPING_OPT_STATS and SOF_TIMESTAMPING_OPT_TSONLY flags
while requesting other SOF_TIMESTAMPING TX timestamps. When the
timestamps are available in the error queue, the stats are returned
in a separate control message of type SCM_TIMESTAMPING_OPT_STATS,
in a list of TLVs (struct nlattr) of types: TCP_NLA_BUSY_TIME,
TCP_NLA_RWND_LIMITED, TCP_NLA_SNDBUF_LIMITED. Unit is microsecond.

This patch exports all the sender chronograph measurements collected
in the previous patches to TCP_INFO interface. Note that busy time
exported includes all the other sending limits (rwnd-limited,
sndbuf-limited). Internally the time unit is jiffy but externally
the measurements are in microseconds for future extensions.

This patch measures the amount of time when TCP runs out of new data
to send to the network due to insufficient send buffer, while TCP
is still busy delivering (i.e. write queue is not empty). The goal
is to indicate either the send buffer autotuning or user SO_SNDBUF
setting has resulted network under-utilization.
The measurement starts conservatively by checking various conditions
to minimize false claims (i.e. under-estimation is more likely).
The measurement stops when the SOCK_NOSPACE flag is cleared. But it
does not account the time elapsed till the next application write.
Also the measurement only starts if the sender is still busy sending
data, s.t. the limit accounted is part of the total busy time.

This patch measures the total time when the TCP stops sending because

once the limit is lifted we are likely in the busy status if we

This patch measures TCP busy time, which is defined as the period
of time when sender has data (or FIN) to send. The time starts when
data is buffered and stops when the write queue is flushed by ACKs
or error events.
Note the busy time does not include SYN time, unless data is
included in SYN (i.e. Fast Open). It does include FIN time even
if the FIN carries no payload. Excluding pure FIN is possible but
would incur one additional test in the fast path, which may not
be worth it.

This patch implements the skeleton of the TCP chronograph
instrumentation on sender side limits:
1) idle (unspec)
2) busy sending data other than 3-4 below
3) rwnd-limited
4) sndbuf-limited
The limits are enumerated 'tcp_chrono'. Since a connection in
theory can idle forever, we do not track the actual length of this
uninteresting idle period. For the rest we track how long the sender
spends in each limit. At any point during the life time of a
connection, the sender must be in one of the four states.
If there are multiple conditions worthy of tracking in a chronograph
then the highest priority enum takes precedence over
the other conditions. So that if something "more interesting"
starts happening, stop the previous chrono and start a new one.
The time unit is jiffy(u32) in order to save space in tcp_sock.
This implies application must sample the stats no longer than every
49 days of 1ms jiffy.

Add the ability to query and set Energy Efficient Ethernet parameters
via ethtool for applicable devices.
This patch doesn't activate full EEE support in cpsw driver, but it
enables reading and writing EEE advertising settings. This way one
can disable advertising EEE for certain speeds.

A recent patch added a new function that is now unused whenever
CONFIG_OF is disabled:
drivers/misc/sram.c:342:12: error: 'atmel_securam_wait' defined but not used [-Werror=unused-function]
There is actually no reason for the #ifdef, because the driver
currently cannot be used in a meaningful way without CONFIG_OF,
and there is no compile-time dependency.
Removing that #ifdef and the respective of_match_ptr() avoids the
warning and simplifies the driver slightly.

Two branches were incorrectly sent without having the necessary
header file changes. Rather than back those out now, I'm replacing
the symbolic names for the clks and resets with the numeric
values to get 'make allmodconfig dtbs' back to work.
After the header file changes are merged, we can revert this
patch.

While logging new directory entries, at tree-log.c:log_new_dir_dentries(),
after we call btrfs_search_forward() we get a leaf with a read lock on it,
and without unlocking that leaf we can end up calling btrfs_iget() to get
an inode pointer. The later (btrfs_iget()) can end up doing a read-only
search on the same tree again, if the inode is not in memory already, which
ends up causing a deadlock if some other task in the meanwhile started a
write search on the tree and is attempting to write lock the same leaf
that btrfs_search_forward() locked while holding write locks on upper
levels of the tree blocking the read search from btrfs_iget(). In this
scenario we get a deadlock.
So fix this by releasing the search path before calling btrfs_iget() at
tree-log.c:log_new_dir_dentries().
