[ Upstream commit ba1124f58afd37d9ff155d4ab7c9f209346aaed9 ]
E830 is the 200G NIC family which uses the ice driver.
Add specific E830 registers. Embed macros to use proper register based on
(hw)->mac_type & name those macros to [ORIGINAL]_BY_MAC(hw). Registers
only available on one of the macs will need to be explicitly referred to
as E800_NAME instead of just NAME. PTP is not yet supported.

Drop @num_entries and @cd params, latter of which was always NULL.
Number of entities to alloc is passed in internal buffer, the outer layer
(that @num_entries was assigned to) meaning is closer to "the number of
requests", which was =1 in all cases.
ice_free_hw_res() was always called with 1 as its @num arg.

Refactor __ice_aq_get_set_rss_lut() to improve reader experience and limit
misuse scenarios (undesired LUT size for given LUT type).
Allow only 3 RSS LUT type+size variants:
PF LUT sized 2048, GLOBAL LUT sized 512, and VSI LUT sized 64, which were
used on default flows prior to this commit.
Prior to the change, code was mixing the meaning of @params->lut_size and
@params->lut_type, flag assigning logic was cryptic, while long defines
made everything harder to follow.
Fix that by extracting some code out to separate helpers.
Drop some of "shift by 0" statements that originated from Intel's
internal HW documentation.
Drop some redundant VSI masks (since ice_is_vsi_valid() gives "valid" for
up to 0x300 VSIs).
After sweeping all the defines out of struct ice_aqc_get_set_rss_lut,
it fits into 7 lines.
Finally apply some cleanup to the callsite
(use of the new enums, tmp var for lengthy bit extraction).
Note that flags for 128 and 64 sized VSI LUT are the same,
and 64 is used everywhere in the code (updated to new enum here), it just
happened that there was 128 in flag name.
__ice_aq_get_set_rss_key() uses the same VSI valid bit, make constant
common for it and __ice_aq_get_set_rss_lut().

The ice_alloc_lan_q_ctx function allocates the queue context array for a
given traffic class. This function uses devm_kcalloc which will
zero-allocate the structure. Thus, prior to any queue being setup by
ice_ena_vsi_txq, the q_ctx structure will have a q_handle of 0 and a q_teid
of 0. These are potentially valid values.
Modify the ice_alloc_lan_q_ctx function to initialize every member of the
q_ctx array to have invalid values. Modify ice_dis_vsi_txq to ensure that
it assigns q_teid to an invalid value when it assigns q_handle to the
invalid value as well.
This will allow other code to check whether the queue context is currently
valid before operating on it.

The current ice driver's GNSS write implementation buffers writes and
works through them asynchronously in a kthread. That's bad because:
- The GNSS write_raw operation is supposed to be synchronous[1][2].
- There is no upper bound on the number of pending writes.
Userspace can submit writes much faster than the driver can process,
consuming unlimited amounts of kernel memory.
A patch that's currently on review[3] ("[v3,net] ice: Write all GNSS
buffers instead of first one") would add one more problem:
- The possibility of waiting for a very long time to flush the write
work when doing rmmod, softlockups.
To fix these issues, simplify the implementation: Drop the buffering,
the write_work, and make the writes synchronous.
I tested this with gpsd and ubxtool.

10 ms is a lot of time to spend busy-waiting. Sleeping is clearly
allowed here, because we have just returned from ice_sq_send_cmd(),
which takes a mutex.
On kernels with HZ=100, this msleep may be twice as long, but I don't
think it matters.
I did not actually observe any retries happening here.

The 'buf_cpy'-related code in ice_sq_send_cmd_retry() looks broken.
'buf' is nowhere copied into 'buf_cpy'.
The reason this does not cause problems is that all commands for which
'is_cmd_for_retry' is true go with a NULL buf.
Let's remove 'buf_cpy'. Add a WARN_ON in case the assumption no longer
holds in the future.

The driver polls for ice_sq_done() with a 100 µs period for up to 1 s
and it uses udelay to do that.
Let's use usleep_range instead. We know sleeping is allowed here,
because we're holding a mutex (cq->sq_lock). To preserve the total
max waiting time, measure the timeout in jiffies.
ICE_CTL_Q_SQ_CMD_TIMEOUT is used also in ice_release_res(), but there
the polling period is 1 ms (i.e. 10 times longer). Since the timeout was
expressed in terms of the number of loops, the total timeout in this
function is 10 s. I do not know if this is intentional. This patch keeps
it.
The patch lowers the CPU usage of the ice-gnss-<dev_name> kernel thread
on my system from ~8 % to less than 1 %.
I received a report of high CPU usage with ptp4l where the busy-waiting
in ice_sq_send_cmd dominated the profile. This patch has been tested in
that usecase too and it made a huge improvement there.

In DCB Willing Mode (FW managed LLDP), when the link partner changes
configuration which requires fewer TCs, the TCs that are no longer
needed are suspended by EMP FW, removed, and never resumed. This occurs
before a MIB change event is indicated to SW. The permanent suspension and
removal of these TC nodes in the scheduler prevents RDMA from being able
to destroy QPs associated with this TC, requiring a CORE reset to recover.
A new DCBX configuration change flow is defined to allow SW driver and
other SW components (RDMA) to properly adjust to the configuration
changes before they are taking effect in HW. This flow includes a
two-way handshake between EMP FW<->LAN SW<->RDMA SW.
List of changes:
- Add 'Execute Pending LLDP MIB' AQC.
- Add 'Pending Event Enable' bit.
- Add additional logic to ignore Pending Event Enable' request
while 'LLDP MIB Chnage' event is disabled.
- Add 'Execute Pending LLDP MIB' AQC sending function to FW,
which is needed to take place MIB Event change.

The driver is currently using ICE_LINK_SPEED_* defines that mirror what
ethtool.h defines, with one exception ICE_LINK_SPEED_UNKNOWN.
This issue is fixed by the following changes:
1. replace ICE_LINK_SPEED_UNKNOWN with 0 because SPEED_UNKNOWN in
ethtool.h is "-1" and that doesn't match the driver's expected behavior
2. transform ICE_LINK_SPEED_*MBPS to SPEED_* using static tables and
fls()-1 to convert from BIT() to an index in a table.

In order to support configuring the device in Double VLAN Mode (DVM),
the DDP and FW have to support DVM. If both support DVM, the PF that
downloads the package needs to update the default recipes, set the
VLAN mode, and update boost TCAM entries.
To support updating the default recipes in DVM, add support for
updating an existing switch recipe's lkup_idx and mask. This is done
by first calling the get recipe AQ (0x0292) with the desired recipe
ID. Then, if that is successful update one of the lookup indices
(lkup_idx) and its associated mask if the mask is valid otherwise
the already existing mask will be used.
The VLAN mode of the device has to be configured while the global
configuration lock is held while downloading the DDP, specifically after
the DDP has been downloaded. If supported, the device will default to
DVM.

The ice hardware contains an embedded chip with firmware which can be
updated using devlink flash. The firmware which runs on this chip is
referred to as the Embedded Management Processor firmware (EMP
firmware).
Activating the new firmware image currently requires that the system be
rebooted. This is not ideal as rebooting the system can cause unwanted
downtime.
In practical terms, activating the firmware does not always require a
full system reboot. In many cases it is possible to activate the EMP
firmware immediately. There are a couple of different scenarios to
cover.
* The EMP firmware itself can be reloaded by issuing a special update
to the device called an Embedded Management Processor reset (EMP
reset). This reset causes the device to reset and reload the EMP
firmware.
* PCI configuration changes are only reloaded after a cold PCIe reset.
Unfortunately there is no generic way to trigger this for a PCIe
device without a system reboot.
When performing a flash update, firmware is capable of responding with
some information about the specific update requirements.
The driver updates the flash by programming a secondary inactive bank
with the contents of the new image, and then issuing a command to
request to switch the active bank starting from the next load.
The response to the final command for updating the inactive NVM flash
bank includes an indication of the minimum reset required to fully
update the device. This can be one of the following:
* A full power on is required
* A cold PCIe reset is required
* An EMP reset is required
The response to the command to switch flash banks includes an indication
of whether or not the firmware will allow an EMP reset request.
For most updates, an EMP reset is sufficient to load the new EMP
firmware without issues. In some cases, this reset is not sufficient
because the PCI configuration space has changed. When this could cause
incompatibility with the new EMP image, the firmware is capable of
rejecting the EMP reset request.
Add logic to ice_fw_update.c to handle the response data flash update
AdminQ commands.
For the reset level, issue a devlink status notification informing the
user of how to complete the update with a simple suggestion like
"Activate new firmware by rebooting the system".
Cache the status of whether or not firmware will restrict the EMP reset
for use in implementing devlink reload.
Implement support for devlink reload with the "fw_activate" flag. This
allows user space to request the firmware be activated immediately.
For the .reload_down handler, we will issue a request for the EMP reset
using the appropriate firmware AdminQ command. If we know that the
firmware will not allow an EMP reset, simply exit with a suitable
netlink extended ACK message indicating that the EMP reset is not
available.
For the .reload_up handler, simply wait until the driver has finished
resetting. Logic to handle processing of an EMP reset already exists in
the driver as part of its reset and rebuild flows.
Implement support for the devlink reload interface with the
"fw_activate" action. This allows userspace to request activation of
firmware without a reboot.
Note that support for indicating the required reset and EMP reset
restriction is not supported on old versions of firmware. The driver can
determine if the two features are supported by checking the device
capabilities report. I confirmed support has existed since at least
version 5.5.2 as reported by the 'fw.mgmt' version. Support to issue the
EMP reset request has existed in all version of the EMP firmware for the
ice hardware.
Check the device capabilities report to determine whether or not the
indications are reported by the running firmware. If the reset
requirement indication is not supported, always assume a full power on
is necessary. If the reset restriction capability is not supported,
always assume the EMP reset is available.
Users can verify if the EMP reset has activated the firmware by using
the devlink info report to check that the 'running' firmware version has
updated. For example a user might do the following:
# Check current version
$ devlink dev info
# Update the device
$ devlink dev flash pci/0000:af:00.0 file firmware.bin
# Confirm stored version updated
$ devlink dev info
# Reload to activate new firmware
$ devlink dev reload pci/0000:af:00.0 action fw_activate
# Confirm running version updated
$ devlink dev info
Finally, this change does *not* implement basic driver-only reload
support. I did look into trying to do this. However, it requires
significant refactor of how the ice driver probes and loads everything.
The ice driver probe and allocation flows were not designed with such
a reload in mind. Refactoring the flow to support this is beyond the
scope of this change.

Define dummy packet headers to allow adding advanced rules in HW. This
header is used as admin queue command parameter for adding a rule.
The firmware will extract correct fields and will use them in look ups.
Define each supported packets header and offsets to words used in recipe.
Supported headers:
- MAC + IPv4 + UDP
- MAC + VLAN + IPv4 + UDP
- MAC + IPv4 + TCP
- MAC + VLAN + IPv4 + TCP
- MAC + IPv6 + UDP
- MAC + VLAN + IPv6 + UDP
- MAC + IPv6 + TCP
- MAC + VLAN + IPv6 + TCP
Add code for creating an advanced rule. Rule needs to match defined
dummy packet, if not return error, which means that this type of rule
isn't currently supported.
The first step in adding advanced rule is searching for an advanced
recipe matching this kind of rule. If it doesn't exist new recipe is
created. Dummy packet has to be filled with the correct header field
value from the rule definition. It will be used to do look up in HW.
Support searching for existing advance rule entry. It is used in case
of adding the same rule on different VSI. In this case, instead of
creating new rule, the existing one should be updated with refreshed VSI
list.
