Avraham Stern b8133439bd wifi: iwlwifi: mvm: trigger PCI re-enumeration in case of PLDR sync
When doing the PLDR flow, the fw goes through a re-read and needs
PCI re-enumeration in order to recover. In this case, skip the mac
start retry and fw dumps as all the fw and registers are invalid
until the PCI re-enumeration.

In addition, print the register that shows the re-read counter
when loading the fw.

Avraham Stern 733eb54f62 wifi: iwlwifi: mei: implement PLDR flow
If the FW needs to do OTP re-read, the driver must notify CSME before
loading the FW so CSME will not try to access the NIC during the
re-read. Once the alive notification is received, CSME is notified
that NIC access is allowed again.

Avraham Stern 5aa7ce31bd wifi: iwlwifi: mei: make sure ownership confirmed message is sent
It is possible that CSME will try to take ownership while the driver
is stopping. In this case, if the CSME takes ownership message arrives
after the driver started unregistering, the iwl_mei_cache->ops is
already invalid, so the host will not answer with the ownership
confirmed message.
Similarly, if the take ownership message arrived after the mac was
stopped or when iwl_mvm_up() failed, setting rfkill will not trigger
sending the confirm message. As a result, CSME will not take
ownership, which will result in a disconnection.

Fix it by sending the ownership confirmed message immediately in such
cases.

if the table doesn't exist in ACPI or is invalid, or if the FW doesn't

This is wrong because those are valid scenarios.  Fix this by not
failing in those cases.

Johannes Berg 971cbe50e6 iwlwifi: make iwl_fw_lookup_cmd_ver() take a cmd_id
Instead of taking the group/command separately, make the function
take a combined command ID. In many cases, this allows us to pass
an existing command ID (e.g. cmd.id), or introduce a new variable
for it, so that we don't use the command ID twice.

This way, we can also use LONG_GROUP implicitly, so we don't need
to spell that out for many commands.

Apart from mvm.h, fw/img.{c,h} changes and some copyright and
indentation updates, this was done with spatch:

If OEM isn't in the allowed list, TAS should be disabled in US/CA.
Currently, if the OEM isn't allowed - we're sending the TAS only
if we are not in US or CA.
But this country check is done before we even know the country
(usually the configuration is ZZ in that stage).
So do the following instead:
1. Check if the current OEM is in the allowed list
2. If not - add US and CA to tas_block_list_array
3. Send the TAS table to FW.

In case of a conflict between BIOS version and FW
version of the PPAG table - the values arrive in the FW in the wrong
places. This happens because we're storing the table in different
structures depending on the BIOS version, not on the FW version,
and so the FW doesn't get what it expect to.
Always store the table in a v2 structure (which is a superset
of v1 and v0).

Also store the table in a structured way and in it's own structure,
rather then storing it in the ppag command structure, similarly to
the WRDS, EWRD and WGDS tables.

Abhishek Naik 9ce505feb1 iwlwifi: mvm: Check ret code for iwl_mvm_load_nvm_to_nic
Return value of the iwl_mvm_load_nvm_to_nic func is not analyzed. If load
NVM to nic func fails and NVM is not loaded to fw properly, then fw may
behave badly and lead to some strange issue. This commit will analyze
return value and if load NVM to nic has failed, then the error code is
sent to the previous func, which will trigger WRT log collection.
iwl_fw_dbg_error_collect() func collects dump only if tri type is
FW_DBG_TRIGGER_ALIVE_TIMEOUT. But when Load NVM to nic function fails
trig_type is FW_DBG_TRIGGER_DRIVER. This commit also has code changes to
collect dump when trig_type is FW_DBG_TRIGGER_DRIVER.

The call to iwl_sar_geo_init() was moved to the end of the
iwl_mvm_sar_geo_init() function, after the table revision is assigned
to the FW command.  But the revision is only known after
iwl_sar_geo_init() is called, so we were always assigning zero to it.

Fix that by moving the assignment code after the iwl_sar_geo_init()
function is called.

Luca Coelho 659844d391 iwlwifi: mvm: send stored PPAG command instead of local
Some change conflicts apparently cause a confusion between a local
variable being used to send the PPAG command and the introduction of a
union for this command.  Most parts of the local command were never
copied from the stored data, so the FW was getting garbage in the
tables instead of getting valid values.

Fix this by completely removing the local and using only the union
that we have stored in fwrt.

Luca Coelho 5a6842455c iwlwifi: mvm: fix the type we use in the PPAG table validity checks
The value we receive from ACPI is a long long unsigned integer but the
values should be treated as signed char.  When comparing the received
value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison,
so the negative value would actually be treated as a very high number.

To solve this issue, assign the value to our table of s8's before
making the comparison, so the value is already converted when we do
so.

We should only allow PPAG to be enabled by OEMs that are in the

vendor string retrieved from SMBIOS to a list maintained in the

the table argument of iwl_sar_geo_init was changed from a pointer a 1d
array of now-removed iwl_per_chain_offset_group_v1 to a pointer to a 2d
array of iwl_per_chain_offset (iwl_per_chain_offset_group_v1 was a
struct containing 2 copies of iwl_per_chain_offset).

So even for version 2 where the second dimension is of length 2, which
means that the underlying memory layout of the array didn't change, this
requires a small change in the way we loop over it, and this was missed.

Additionally, for the case of version 3 where the second dimension is now
3, in order to fill the first two elements of each row correctly (lb and
hb), iwl_sar_geo_init must get the true number of bands supported.
But because we don't yet store any values for the 3rd (uhb) band, skip
that band.

ADD_STA_CMD_API_S ver 12 was added in order to properly support
auxiliary activities in CDB NICs. In the new version we don't need
to allocate an aux station at initialization, instead we add an
aux station only when an auxiliary activity that requires a dedicated Tx
queue is needed. For now the only case we need this kind of activity is
when using hot spot 2.0

Luca Coelho 64f55156f7 iwlwifi: mvm: don't send RFH_QUEUE_CONFIG_CMD with no queues
If we have only a single RX queue, such as when MSI-X is not
available, we should not send the RFH_QUEUEU_CONFIG_CMD, because our
only queue is the same as the command queue and will be configured as
part of the context info.  Our code was actually trying to send the
command with 0 queues, which caused UMAC assert 0x1D04.

Fix that by not sending the command when we have a single queue.

Ilan Peer b68bd2e314 iwlwifi: mvm: Add FTM initiator RTT smoothing logic
The overcome instabilities in the RTT results add smoothing logic
to the reported results. In short, the smoothing logic tracks the
RTT average of each responder for a period of time, and in case
a new RTT results is found to be a spur, the tracked RTT average
is reported instead of the current RTT measurement.

Smooth logic debug configuration using iwl-dbg-cfg.ini:

- MVM_FTM_INITIATOR_ENABLE_SMOOTH: Set to 1 to enable smoothing logic
 (default=0).
- MVM_FTM_INITIATOR_SMOOTH_ALPHA: A value between 0 - 100, defining
  the weight of the current RTT results vs. the RTT average tracked
  based on the previous results. A value of 100 means use only the
  current RTT results.
- MVM_FTM_INITIATOR_SMOOTH_AGE_SEC: The maximal time in seconds in which
  the RTT average tracked based on previous results is considered valid.
- MVM_FTM_INITIATOR_SMOOTH_UNDERSHOOT: if the current RTT is positive
  and below the RTT average by at least this value, report the average
  RTT instead of the current one. In units of picoseconds.
- MVM_FTM_INITIATOR_SMOOTH_OVERSHOOT: if the current RTT is positive
  and above the RTT average by at least this value, report the average
  RTT instead of the current one. In units of picoseconds.

Luca Coelho 1edd56e69d iwlwifi: fix WGDS check when WRDS is disabled
In the reference BIOS implementation, WRDS can be disabled without
disabling WGDS.  And this happens in most cases where WRDS is
disabled, causing the WGDS without WRDS check and issue an error.

To avoid this issue, we change the check so that we only considered it
an error if the WRDS entry doesn't exist.  If the entry (or the
selected profile is disabled for any other reason), we just silently
ignore WGDS.

David S. Miller 22f33971aa wireless-drivers-next patches for v5.7
Third set of patches for v5.7. Nothing really special this time,
 business as usual.
 
 When pulling this to net-next there's again a conflict in:
 
 drivers/net/wireless/intel/iwlwifi/pcie/drv.c
 
 To solve this drop these three lines from the conflict (the first hunk
 from "HEAD") as the whole AX200 block was moved above in the same
 file:
 
 	IWL_DEV_INFO(0x2723, 0x1653, iwl_ax200_cfg_cc, iwl_ax200_killer_1650w_name),
 	IWL_DEV_INFO(0x2723, 0x1654, iwl_ax200_cfg_cc, iwl_ax200_killer_1650x_name),
 	IWL_DEV_INFO(0x2723, IWL_CFG_ANY, iwl_ax200_cfg_cc, iwl_ax200_name),
 
 And keep all the __IWL_DEV_INFO() entries (the second hunk). In other
 words, take everything from wireless-drivers-next. When running 'git
 diff' after the resolution the output should be empty.
 
 Major changes:

Luca Coelho 095650c054 iwlwifi: add support for version 2 of SOC_CONFIGURATION_CMD
This new command is mostly backwards compatible, with the exception
that the device_type element was changed into a bitmask.  The device
type bit remains the same (because we only had 0 and 1 anyway), but
when using v1 we can't set any other bits, because that would change
the integer.

Other than that, the struct remains the same and the driver can set
the device_type bit in both cases, but it can only set the low_latency
bit if VER_2 is used.

Luca Coelho 7897dfa2bc iwlwifi: move integrated, extra_phy and soc_latency to trans_cfg
These values are selected based on the PCI device ID, so the decision
to use them can be made early.  By moving them to the trans_cfg, we
avoid duplicating the large cfg structs for small pieces of
data (sometimes a single boolean).  This will also allow us to make
more decisions based on, for instance, the SoC type in used.

The trans_cfg concept changes a bit, because previously it was used
only to boot the device before reading further characteristics and now
it also contains more data that is associated with the device ID.

Gil Adam 6ce1e5c0c2 iwlwifi: support per-platform antenna gain
TX power limits as defined in the OTP assume the worst case scenario
in terms of the platform's atenna gain, but most platforms are below
that value so they can use more TX power without passing the regulatory
limit. If the platform indicates in the BIOS that it indeed has lower
gain, and the geographic location allows it, higher TX power can be
used. The driver reads the PPAG (Per-Platform Antenna Gain) data from
BIOS (if it exists), validates it and sends the appropriate command to
the FW. This flow happens once at FW init, in case of suspend/resume
there is no need to read again from BIOS as we save those values during
init, so just send the PPAG command again to FW.

Luca Coelho f5a47fae6a iwlwifi: mvm: fix version check for GEO_TX_POWER_LIMIT support
We erroneously added a check for FW API version 41 before sending
GEO_TX_POWER_LIMIT, but this was already implemented in version 38.
Additionally, it was cherry-picked to older versions, namely 17, 26
and 29, so check for those as well.

Luca Coelho 39bd984c20 iwlwifi: mvm: don't send GEO_TX_POWER_LIMIT on version < 41
Firmware versions before 41 don't support the GEO_TX_POWER_LIMIT
command, and sending it to the firmware will cause a firmware crash.
We allow this via debugfs, so we need to return an error value in case
it's not supported.

This had already been fixed during init, when we send the command if
the ACPI WGDS table is present.  Fix it also for the other,
userspace-triggered case.

Haim Dreyfuss 0c3d728223 iwlwifi: Add support for SAR South Korea limitation
South Korea is adding a more strict SAR limit called "Limb SAR".
Currently, WGDS SAR offset group 3 is not used (not mapped to any country).
In order to be able to comply with South Korea new restriction:
- OEM will use WGDS SAR offset group 3 to South Korea limitation.
- OEM will change WGDS revision to 1 (currently latest revision is 0)
	to notify that Korea Limb SAR applied.
- Driver will read the WGDS table and pass the values to FW (as usual)
- Driver will pass to FW an indication that Korea Limb SAR is applied
	in case table revision is 1.

Emmanuel Grumbach b3500b472c iwlwifi: fix load in rfkill flow for unified firmware
When we have a single image (same firmware image for INIT and
OPERATIONAL), we couldn't load the driver and register to the
stack if we had hardware RF-Kill asserted.

Fix this. This required a few changes:

1) Run the firmware as part of the INIT phase even if its
   ucode_type is not IWL_UCODE_INIT.
2) Send the commands that are sent to the unified image in
   INIT flow even in RF-Kill.
3) Don't ask the transport to stop the hardware upon RF-Kill
   interrupt if the RF-Kill is asserted.
4) Allow the RF-Kill interrupt to take us out of L1A so that
   the RF-Kill interrupt will be received by the host (to
   enable the radio).

Johannes Berg 72d3c7bbc9 iwlwifi: mvm: don't attempt debug collection in rfkill
If we fail to initialize because rfkill is enabled, then trying
to do debug collection currently just fails. Prevent that in the
high-level code, although we should probably also fix the lower
level code to do things more carefully.

It's not 100% clear that it fixes this commit, as the original
dump code at the time might've been more careful. In any case,
we don't really need to dump anything in this expected scenario.

Haim Dreyfuss 48e775e66e iwlwifi: mvm: add support for 32kHz external clock indication
In low power modes, the chip clock source for platform integrated
devices is 32kHz. It is generated internally and supplied by a crystal
oscillator. However using a 32kHz sourced from crystal oscillator
has high power penalty.

There is an option to get an external 32kHz clock from the platform. Past
experience shows that the reliability is platform dependent,
i.e. on some platforms it works good and on other it doesn’t.

Working from external clock will save 0.5 mW in sleep state, from overall
1.8mW that we have today, i.e. almost 30%.

Each OEM can enable or disable the use of the external 32kHz clock by
setting a BIOS configuration. In case the OEM configured to use 32kHz
external clock the driver will pass this indication to the FW.

Mordechay Goodstein f130bb75d8 iwlwifi: add FW recovery flow
Add new API and TLV for the ability to send commands in the beginning
and end of reset flow.

The full flow of recovery is:

1. While loading FW, get address (from the TLV) of target buffer
   to read in case of reset
2. If an error/assert happens read the address data from step 1.
3. Reset the HW and load the FW.
4. Send the data read in step 2.
5. Add station keys
6. Send notification to FW that reset flow is done.

The main use of the recovery flow is for support in PN/SN recovery
when offloaded
