git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next
First batch of iwlwifi updates for v4.16
* Rename the temporary name A000 to 22000;
* Change in the way we print the firmware version;
* Remove some unused code;
* Other small improvements;
kvalo:
There were conflicts, I fixed them with taking into account commit c2c48ddfc8b0
("iwlwifi: fix firmware names for 9000 and A000 series hw"):
CONFLICT (content): Merge conflict in drivers/net/wireless/intel/iwlwifi/iwl-config.h
CONFLICT (modify/delete): drivers/net/wireless/intel/iwlwifi/cfg/a000.c deleted in ca495785063c428641cc6df8888afd2587ca6677 and modified in HEAD. Version HEAD of drivers/net/wireless/intel/iwlwifi/cfg/a000.c left in tree.

The family name A000 was just a place-holder when we didn't know what
the official name would be yet. Now we know that the family name is
22000, so rename all occurrences accordingly.

Since iwl_mvm_start_p2p_roc() is only called from iwl_mvm_roc(),
which already flushes the same work item, doing it again in it
is superfluous. Remove it and move the comment to the first one.

The ucode_major and ucode_minor were swapped. This has
no practical consequences since those fields are not used.
Same goes for umac_major and umac_minor which were only
printed under certain debug flags.

This feature was actually removed from firmware, but without
ever telling the driver. Since nobody is actually using it,
just remove it entirely without bothering with a capability
check.

When we are in a search cycle, we try different combinations
of parameters. Those combinations are called 'columns'.
When we switch to a new column, we first need to check if
this column has a suitable rate, if not, we can't try it.
This means we must not erase the statistics we gathered
for the previous column until we are sure that we are
indeed switching column.
The code that tries to switch to a new column first sets
a whole bunch of things for the new column, and only then
checks that we can find suitable rates in that column.
While doing that, the code mistakenly erased the rate
statistics. This code was right until
struct iwl_scale_tbl_info grew up for TPC.
Fix this to make sure we don't erase the rate statistics
until we are sure that we can indeed switch to the new
column.
Note that this bug is really harmless since it causes a
change in the behavior only when we can't find any rate
in the new column which should really not happen. In the
case we do find a suitable we reset the rate statistics
a few lines later anyway.

In A000 family, compressed BA notifs can include MGMT
frames, so don't fail RXs in such a case.
While at it, since in A000 the TID for MGMT frames is
15, treat it in the RX flow as if received TID 8. This
way we won't require special handling of this TID.

Pull timer updates from Thomas Gleixner:
- The final conversion of timer wheel timers to timer_setup().
A few manual conversions and a large coccinelle assisted sweep and
the removal of the old initialization mechanisms and the related
code.
- Remove the now unused VSYSCALL update code
- Fix permissions of /proc/timer_list. I still need to get rid of that
file completely
- Rename a misnomed clocksource function and remove a stale declaration

This converts all remaining setup_timer() calls that use a nested field
to reach a struct timer_list. Coccinelle does not have an easy way to
match multiple fields, so a new script is needed to change the matches of
"&_E->_timer" into "&_E->_field1._timer" in all the rules.

This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.
Casting from unsigned long:
void my_callback(unsigned long data)
{
struct something *ptr = (struct something *)data;
...
}
...
setup_timer(&ptr->my_timer, my_callback, ptr);
and forced object casts:
void my_callback(struct something *ptr)
{
...
}
...
setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);
become:
void my_callback(struct timer_list *t)
{
struct something *ptr = from_timer(ptr, t, my_timer);
...
}
...
timer_setup(&ptr->my_timer, my_callback, 0);
Direct function assignments:
void my_callback(unsigned long data)
{
struct something *ptr = (struct something *)data;
...
}
...
ptr->my_timer.function = my_callback;
have a temporary cast added, along with converting the args:
void my_callback(struct timer_list *t)
{
struct something *ptr = from_timer(ptr, t, my_timer);
...
}
...
ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;
And finally, callbacks without a data assignment:
void my_callback(unsigned long data)
{
...
}
...
setup_timer(&ptr->my_timer, my_callback, 0);
have their argument renamed to verify they're unused during conversion:
void my_callback(struct timer_list *unused)
{
...
}
...
timer_setup(&ptr->my_timer, my_callback, 0);
The conversion is done with the following Coccinelle script:
spatch --very-quiet --all-includes --include-headers \
-I ./arch/x86/include -I ./arch/x86/include/generated \
-I ./include -I ./arch/x86/include/uapi \
-I ./arch/x86/include/generated/uapi -I ./include/uapi \

iwlwifi: first set of fixes for 4.15
* Support new FW API version of scan cmd (used in FW version 34);
* Add a bunch of PCI IDs and fix configuration structs for A000
devices;
* Fix the exported firmware name strings for 9000 and A000 devices;

iwlwifi 9000 and a0000 series hw contains an extra dash in firmware
file name as seeen in modinfo output for kernel 4.14:
firmware: iwlwifi-9260-th-b0-jf-b0--34.ucode
firmware: iwlwifi-9260-th-a0-jf-a0--34.ucode
firmware: iwlwifi-9000-pu-a0-jf-b0--34.ucode
firmware: iwlwifi-9000-pu-a0-jf-a0--34.ucode

firmware: iwlwifi-Qu-a0-jf-b0--34.ucode
firmware: iwlwifi-Qu-a0-hr-a0--34.ucode
Fix that by dropping the extra adding of '"-"'.

A lot of PCI IDs were missing and there were some problems with the
configuration and firmware selection for devices on the 9000 series.
Fix the firmware selection by adding files for the B-steps; add
configuration for some integrated devices; and add a bunch of PCI IDs
(mostly for integrated devices) that were missing from the driver's
list.
Without this patch, a lot of devices will not be recognized or will
try to load the wrong firmware file.

Newer firmware versions (such as iwlwifi-8000C-34.ucode) have
introduced an API change in the SCAN_REQ_UMAC command that is not
backwards compatible. The driver needs to detect and use the new API
format when the firmware reports it, otherwise the scan command will
not work properly, causing a command timeout.
Fix this by adding a TLV that tells the driver that the new API is in
use and use the correct structures for it.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=197591

In case of a hardware restart the BA session data in HW is lost
so the reorder buffer simply passes the frames to mac80211 as is
as there is no NSSN set. Instead, we will drop these frames
before they reach the reorder buffer. mac80211 drops such frames anyway,
but we shouldn't rely on that. In addition it saves some
processing time

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.
The RCU lifetime on baid_data is unclear, so this adds a direct copy of the
rcu_ptr passed to the original callback. It may be possible to improve this
to just use baid_data->mvm->baid_map[baid_data->baid] instead.

In the mac flush flow, we should flush all existing queues.
Since FW API for a000 devices is flush per RA-TID, simply
flush all stations with all tids.
From FW perspective, asking to flush a TID that doesn't have
a queue is valid, so we can just set all bits in the TID mask.

Currently we return early from sync_rx_queues for a000 devices.
This may cause, in case of a non-empty reorder buffer, a warning
later on since the RX queue isn't getting the notification to
empty it.
A better approach would be to send the notification for the default
queue only.
Do this hard coded for now, until we will have the API to enable
multi queue for a000 devices.

Commit a6d24fad00d9 ("iwlwifi: pcie: dump registers when HW becomes
inaccessible") added a function to dump pcie config registers and
memory mapped registers on a failure. It is currently only accessible
within trans.c. Add it to struct iwl_trans_ops, so that failure cases
in other files can call it. While there, add a call to this function
from iwl_pcie_load_firmware_chunk in pcie/tx.c, since this is a common
failure case seen on some platforms.

When there is a reorder timeout, we may get to a situation
where we have the timeout latency for all the next 64 frames.
This happens since NSSN is behind for a while, and the driver
won't release the frames, since it is not allowed by NSSN.
As a result the frame is stored in the reorder buffer although
there is no hole, and released 100 ms later.
Add a direct comparison to the reorder buffer head, and release
immediately if possible.
For example:
Frame 0 is missed. We receive frame 1, and store it in the buffer.
After 100 ms, frame 1 is released and reorder buffer head is 2.
We then receive frame 2, with NSSN 0, and store it instead of
releasing it.

We don't plan to have products with 3 antennas in the near
future. All the rest of the code follows the same
assumption as well.
Remove the support for antenna C from rs_toggle_ant.
When trying to toggle from ANT_B, this avoids to go through
ANT_C, discover that it doesn't exist and continue to ANT_A.
In MIMO, this avoids to do ANT_AB -> ANT_BC -> ANT_AC and
back to ANT_AB.

After a FW reset on A000 NICs, the driver doesn't
set the seq number when re-allocating the queues.
This in turn leads to a mismatch between the seq
number the driver thinks each frame has, and the
actual seq num given by the HW.
This especially causes issues with aggregations,
since the driver could be waiting to start an
aggregation and queue traffic from the mac80211
until then, when actually it shouldn't be waiting.

Currently the code is mixing defines and is inconsistent.
When enabling a queue, we usually configure the scheduler
with IWL_FRAME_LIMIT - 64.
When sending to firmware the rate scaling, we limit aggregation
to LINK_QUAL_AGG_FRAME_LIMIT_DEF - 63, due to a scheduler bug.
Given that, clean up the following:
- Fix a stray queue enablement with LINK_QUAL_AGG_FRAME_LIMIT_DEF.
- Change the comparison that tests if queue needs to be reconfigured
to be compared directly to how it was configured.
This also saves the redundant round down of the buffer size just
for the sake of comparing it, making the code more readable.
- Better document gen2 logic

The reason station id and tid fields are both in baid data and

Now that we may have up to 256 entries per reorder buffer, and possibly up
to 16 queues, we can use a LOT of memory for this (64k for each station).
Allocate it according to what we need, which is of course much less for HT
stations (only 16k at a max of 16 queues).
However, this comes at the expense of complicating the code a bit to
calculate the right entry structure to use for each frame.
