There is a hardware power-saving problem with the Lenovo N60z
board. When turn it on and leave it for 10 hours, there is a
20% chance that a nvme disk will not wake up until reboot.

RSS is controlled by the Rx filter tables. Program rules matching
on appropriate traffic types and set hashing fields using actions.
We need a separate set of rules for broadcast and multicast
because the action there needs to include forwarding to BMC.
This patch only initializes the default settings, the control
of the configuration using ethtool will come soon.
With this the necessary rules are put in place to enable Rx of packets by
the host.

Program the Rx TCAM to control L2 forwarding. Since we are in full
control of the NIC we need to make sure we include BMC forwarding
in the rules. When host is not present BMC will program the TCAM
to get onto the network but once we take ownership it's up to
Linux driver to make sure BMC L2 addresses are handled correctly.

Handle Rx packets with basic csum and Rx hash offloads.
NIC writes back to the completion ring a head buffer descriptor
(data buffer allocated from header pages), variable number of payload
descriptors (data buffers in payload pages), an optional metadata
descriptor (type 2) and finally the primary metadata descriptor
(type 3).
This format makes scatter support fairly easy - start gathering
the pages when we see head page, gather until we see the primary
metadata descriptor, do the processing. Use XDP infra to collect
the packet fragments as we traverse the descriptors. XDP itself
is not supported yet, but it will be soon.

Handle Tx of simple packets. Support checksum offload and gather.
Use .ndo_features_check to make sure packet geometry will be
supported by the HW, i.e. we can fit the header lengths into
the descriptor fields.
The device writes to the completion rings the position of the tail
(consumer) pointer. Read all those writebacks, obviously the last
one will be the most recent, complete skbs up to that point.

Add basic support for detecting the link and reporting it at the netdev
layer. For now we will just use the values reporeted by the firmware as the
link configuration and assume that is the current configuration of the MAC
and PCS.
With this we start the stubbing out of the phylink interface that will be
used to provide the configuration interface for ethtool in a future patch
set.
The phylink interface isn't an exact fit. As such we are currently working
around several issues in this patch set that we plan to address in the
future such as:
1. Support for FEC
2. Support for multiple lanes to handle 50GbaseR2 vs 50GbaseR1
3. Support for BMC

After the driver loads we need to get some initial capabilities from the
firmware to determine what the device is capable of and what functionality
needs to be enabled. Specifically we receive information about the current
state of the link and if a BMC is present.
After that when we bring the interface up we will need the ability to take
ownership from the FW. To do that we will need to notify it that we are
taking control before we start configuring the traffic classifier and MAC.
Once we have ownership we need to notify the firmware that we are still
present and active. To do that we will send a regular heartbeat to the FW.
If the FW doesn't receive the heartbeat in a timely fashion it will retake
control of the RPC and MAC and assume that the host has gone offline.

Implement control path parts of Rx queue handling.
The NIC consumes memory in pages. It takes a full page and places
packets into it in a configurable manner (with the ability to define
headroom / tailroom as well as head alignment requirements).
As mentioned in prior patches there are two page submissions queues
one for packet headers and second (optional) for packet payloads.
For now feed both queues from a single page pool.
Use the page pool "fragment" API, as we can't predict upfront
how the page will be sliced.

Implement basic management operations for Tx queues.
Allocate memory for submission and completion rings.
Learn how to start the queues, stop them, and wait for HW
to be idle.
We call HW rings "descriptor rings" (stored in ring->desc),
and SW context rings "buffer rings" (stored in ring->*_buf union).
This is the first patch which actually touches CSRs so add CSR
helpers.
No actual datapath / packet handling here, yet.

Allocate a netdev and figure out basics like how many queues
we need, MAC address, MTU bounds. Kick off a service task
to do various periodic things like health checking.
The service task only runs when device is open.
We have four levels of objects here:
- ring - A HW ring with head / tail pointers,
- triad - Two submission and one completion ring,
- NAPI - NAPI, with one IRQ and any number of Rx and Tx triads,
- Netdev - The ultimate container of the rings and napi vectors.
The "triad" is the only less-than-usual construct. On Rx we have
two "free buffer" submission rings, one for packet headers and
one for packet data. On Tx we have separate rings for XDP Tx
and normal Tx. So we ended up with ring triplets in both
directions.
We keep NAPIs on a local list, even though core already maintains a list.
Later on having a separate list will matter for live reconfig.
We introduce the list already, the churn would not be worth it.

Add a mechanism for sending messages to and receiving messages
from the FW. The FW has fairly limited functionality, so the
mechanism doesn't have to support high message rate.
Use device mailbox registers to form two rings, one "to" and
one "from" the device. The rings are just a convention between
driver and FW, not a HW construct. We don't expect messages
larger than 4k so use page-sized buffers.

Saeed Mahameed says:
====================
aux-sysfs-irqs
Shay Says:
==========
Introduce auxiliary bus IRQs sysfs
Today, PCI PFs and VFs, which are anchored on the PCI bus, display their
IRQ information in the <pci_device>/msi_irqs/<irq_num> sysfs files. PCI
subfunctions (SFs) are similar to PFs and VFs and these SFs are anchored
on the auxiliary bus. However, these PCI SFs lack such IRQ information
on the auxiliary bus, leaving users without visibility into which IRQs
are used by the SFs. This absence makes it impossible to debug
situations and to understand the source of interrupts/SFs for
performance tuning and debug.
Additionally, the SFs are multifunctional devices supporting RDMA,
network devices, clocks, and more, similar to their peer PCI PFs and
VFs. Therefore, it is desirable to have SFs' IRQ information available
at the bus/device level.
To overcome the above limitations, this short series extends the
auxiliary bus to display IRQ information in sysfs, similar to that of
PFs and VFs.
It adds an 'irqs' directory under the auxiliary device and includes an
<irq_num> sysfs file within it.
For example:
$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/
50 51 52 53 54 55 56 57 58
Patch summary:
patch-1 adds auxiliary bus to support irqs used by auxiliary device

bus

While transmitting with rx_len == 0, the RX FIFO is not going to be
emptied in the interrupt handler. A subsequent transfer could then
read crap from the previous transfer out of the RX FIFO into the
start RX buffer. The core provides a register that will empty the RX and
TX FIFOs, so do that before each transfer.

mchp_corespi_init() reads the CONTROL register, sets the master and
motorola bits, but doesn't write the value back to the register. The
function also doesn't ensure the controller is disabled at the start,
which may present a problem if the controller was used by an
earlier boot stage as some settings (including the mode) can only be
modified while the controller is disabled.

requires it
Setting up many of the registers for a new SPI transfer involves
unconditionally disabling the SPI controller, writing the register
value and re-enabling the controller. This is being done for registers
even when the value is unchanged and is also done for registers that
don't require the controller to be disabled for the change to take
effect. Make an effort to detect changes to the register values, and
only disables the controller if the new register value is different
and disabling the controller is required. This stops the controller
being repeated disabled and the bus going tristate before every
transfer.

TX FIFO
Setting up many of the registers for a new SPI transfer requires the
SPI controller to be disabled after set_cs() has been called to assert
the chip select line. However, disabling the controller results in the
SCLK and MOSI output pins being tristate, which can cause clock
transitions to be seen by a slave device whilst SS is active. To fix
this, the CS is only set to inactive inline, whilst setting it active
is deferred until all registers are set up and the any controller
disables have been completed.

It is possible for the TXDONE interrupt be raised if the tx FIFO becomes
temporarily empty while transmitting, resulting in recursive calls to
mchp_corespi_write_fifo() and therefore a garbage message might be
transmitted depending on when the interrupt is triggered. Moving all of
the tx FIFO writes out of the TXDONE portion of the interrupt handler
avoids this problem.
Most of rest of the TXDONE portion of the handler is problematic too.
Only reading the rx FIFO (and finalising the transfer) when the TXDONE
interrupt is raised can cause the transfer to stall, if the final bytes
of rx data are not available in the rx FIFO when the final TXDONE
interrupt is raised. The transfer should be finalised regardless of
which interrupt is raised, provided that all tx data has been set and
all rx data received.
The first issue was encountered "in the wild", the second is
theoretical.

dasd_add_busid() can return an error via ERR_PTR() if an allocation
fails. However, two callsites in dasd_copy_pair_store() do not check
the result, potentially resulting in a NULL pointer dereference. Fix
this by checking the result with IS_ERR() and returning the error up
the stack.

`args->cfg[4]` is configured in Indirect Dispatch using the number of
batches. Currently, for all V3D tech versions, `args->cfg[4]` equals the
number of batches subtracted by 1. But, for V3D 7.1.6 and later, we must not
subtract 1 from the number of batches.
Implement the fix by checking the V3D tech version and revision.
Fixes several `dEQP-VK.synchronization*` CTS tests related to Indirect Dispatch.

In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.
Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

Change the API to select MAC default time stamping instead of the PHY.
Indeed the PHY is closer to the wire therefore theoretically it has less
delay than the MAC timestamping but the reality is different. Due to lower
time stamping clock frequency, latency in the MDIO bus and no PHC hardware
synchronization between different PHY, the PHY PTP is often less precise
than the MAC. The exception is for PHY designed specially for PTP case but
these devices are not very widespread. For not breaking the compatibility
default_timestamp flag has been introduced in phy_device that is set by
the phy driver to know we are using the old API behavior.
