net: hix5hd2_gmac: add tx sg feature and reset/clock control signals
The "hix5hd2" is SoC name, add the generic ethernet driver compatible string.
The "hisi-gemac-v1" is the basic version and "hisi-gemac-v2" adds
the SG/TXCSUM/TSO/UFO features.
This patch set only adds the SG(scatter-gather) driver for transmitting,
the drivers of other features will be submitted later.
Add the MAC reset control signals and clock signals.
We make these signals optional to be backward compatible with
the hix5hd2 SoC.
Changes in v2:
- Make the compatible string changes be a separate patch and
the most specific string come first than the generic string
as advised by Rob.
- Make the MAC reset control signals and clock signals optional
to be backward compatible with the hix5hd2 SoC.
- Change the compatible string and give the clock a specific name
in hix5hd2 dts file.

The "mac_core_rst" represents "mac core reset signal", it resets
the mac core including packet processing unit, descriptor processing unit,
tx engine, rx engine, control unit.
The "mac_ifc_rst" represents "mac interface reset signal", it resets
the mac interface. The mac interface unit connects mac core and
data interface like MII/RMII/RGMII. After we set a new value of
interface mode, we must reset mac interface to reload the new mode value.
The "mac_core_rst" and "mac_ifc_rst" are both optional to be
backward compatible with the hix5hd2 SoC.
The "phy_rst" represents "phy reset signal", it does a hardware reset
on the PHY chip. This reset signal is optional if the PHY can work well
without the hardware reset.
Add one more clock signal, the existing is MAC core clock,
and the new one is MAC interface clock.
The MAC interface clock is optional to be backward compatible with
the hix5hd2 SoC.

Minor BPF cleanups and digest
First two patches are minor cleanups, and the third one adds
a prog digest. For details, please see individual patches.
After this one, I have a set with tracepoint support that makes
use of this facility as well.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
When loading a BPF program via bpf(2), calculate the digest over
the program's instruction stream and store it in struct bpf_prog's
digest member. This is done at a point in time before any instructions
are rewritten by the verifier. Any unstable map file descriptor
number part of the imm field will be zeroed for the hash.
fdinfo example output for progs:
# cat /proc/1590/fdinfo/5
pos: 0
flags: 02000002
mnt_id: 11
prog_type: 1
prog_jited: 1
prog_digest: b27e8b06da22707513aa97363dfb11c7c3675d28
memlock: 4096
When programs are pinned and retrieved by an ELF loader, the loader
can check the program's digest through fdinfo and compare it against
one that was generated over the ELF file's program section to see
if the program needs to be reloaded. Furthermore, this can also be
exposed through other means such as netlink in case of a tc cls/act
dump (or xdp in future), but also through tracepoints or other
facilities to identify the program. Other than that, the digest can
also serve as a base name for the work in progress kallsyms support
of programs. The digest doesn't depend/select the crypto layer, since
we need to keep dependencies to a minimum. iproute2 will get support
for this facility.

1) Old code was hard to maintain, due to complex lock chains.
(We probably will be able to remove some kfree_rcu() in callers)
2) Using a single timer to update all estimators does not scale.
3) Code was buggy on 32bit kernel (WRITE_ONCE() on 64bit quantity
is not supposed to work well)
In this rewrite :
- I removed the RB tree that had to be scanned in
gen_estimator_active(). qdisc dumps should be much faster.
- Each estimator has its own timer.
- Estimations are maintained in net_rate_estimator structure,
instead of dirtying the qdisc. Minor, but part of the simplification.
- Reading the estimator uses RCU and a seqcount to provide proper
support for 32bit kernels.
- We reduce memory need when estimators are not used, since
we store a pointer, instead of the bytes/packets counters.
- xt_rateest_mt() no longer has to grab a spinlock.

Occasionally, clang (e.g. version 3.8.1) translates a sum between two
constant operands using a BPF_OR instead of a BPF_ADD. The verifier is
currently not handling this scenario, and the destination register type
becomes UNKNOWN_VALUE even if it's still storing a constant. As a result,
the destination register cannot be used as argument to a helper function
expecting a ARG_CONST_STACK_*, limiting some use cases.

all combinations are supported, and stack boundaries are still verified

tcp: tsq: performance series
Under very high TX stress, CPU handling NIC TX completions can spend
considerable amount of cycles handling TSQ (TCP Small Queues) logic.
This patch series avoids some atomic operations, but most notable
patch is the 3rd one, allowing other cpus processing ACK packets and
calling tcp_write_xmit() to grab TCP_TSQ_DEFERRED so that
tcp_tasklet_func() can skip already processed sockets.
This avoid lots of lock acquisitions and cache lines accesses,
particularly under load.
In v2, I added :
- tcp_small_queue_check() change to allow 1st and 2nd packets
in write queue to be sent, even in the case TX completion of
already acknowledged packets did not happen yet.
This helps when TX completion coalescing parameters are set
even to insane values, and/or busy polling is used.
- A reorganization of struct sock fields to
lower false sharing and increase data locality.
- Then I moved tsq_flags from tcp_sock to struct sock also
to reduce cache line misses during TX completions.
I measured an overall throughput gain of 22 % for heavy TCP use
over a single TX queue.

Similarly, the monitor control register has been reworked.
The mv88e6390 has something odd in its EDSA tagging implementation,

tagging. This is the first device with EDSA support where we need to

if EDSA is supported, it will be used. Hence the register layout has
