e713b5ba6f mac80211: ath10k: search all IEs for variant before falling back
This patch adds the patch that was posted to ath10k-devel ML:
<https://patchwork.kernel.org/patch/10233491/>
|From: Thomas Hebb <tommyhebb@gmail.com>
|Subject: [PATCH] ath10k: search all IEs for variant before falling back
|Date: Wed, 21 Feb 2018 11:43:39 -0500
|[...]
|This patch fixes the issue by first searching the entire file for the ID
|with variant, and searching for the fallback ID only if that search
|fails. It also includes some code cleanup in the area, as
|ath10k_core_fetch_board_data_api_n() no longer does its own string
|mangling to remove the variant from an ID, instead leaving that job to a
|new flag passed to ath10k_core_create_board_name().
|
|I've tested this patch on a QCA4019 and verified that the driver behaves
|correctly for 1) both fallback and variant BDFs present, 2) only fallback
|BDF present, and 3) no matching BDFs present.
|
|Fixes: 1657b8f84ed9 ("ath10k: search SMBIOS for OEM board file extension")

Note: 937-ath10k-calibration-variant.patch has been reassigned a new 081
number, as it now ships with upstream.... But also because this patch
requires the change in ath10k_core_create_board_name().

ath9k, ath10k(-ct): move spectral scan support under a separate config symbol
Backport patches that separate spectral scan support from general debugfs
support of ath9k/ath10k; this allows to remove the dependency on
KERNEL_RELAY from these driver packages even with debugfs enabled and
avoids the memory footprint of the relay buffers allocated by ath9k/ath10k
even when they aren't used at all.

The KERNEL_RELAY dependency is moved to a new config symbol that enables
spectral scan support in these drivers.

f39fc67c8e mac80211: ath10k: search DT for BDF variant info
Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on QCA4019 using bus, bmi-chip-id and
bmi-board-id.

The problem, however, can occur when the (default) board data file cannot
fulfill the vendor requirements and it is necessary to use a different
board data file.

This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
Something similar has to be provided for systems without SMBIOS but with
device trees. No solution was specified by QCA and therefore a new one has
to be found for ath10k.

The device tree requires addition strings to define the variant name

    wifi@a000000 {
    	status = "okay";
    	qcom,ath10k-calibration-variant = "RT-AC58U";
    };

    wifi@a800000 {
    	status = "okay";
    	qcom,ath10k-calibration-variant = "RT-AC58U";
    };

This would create the boarddata identifiers for the board-2.bin search

 *  bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U
 *  bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U

from tag v4.14-rc2-1

Then run this:
./gentree.py --git-revision v4.14-rc2 --clean  <path to linux repo> ../backports-4.14-rc2-1

This also adapts the ath10k-ct and mt76 driver to the changed cfg80211

1b2c93988f mac80211: add dev_coredumpm() function
dev_coredumpm() was added with kernel 4.7, but it is used by iwlwifi.
When the dev coredump framework form compat-wireless is used this is not
a problem because it already contains this, but this is deactivated if
the build system finds out that it is already included in the kernel we
compile against. This option was now activated by the bluetooth driver
btmrvl. Having dev coredump in the kernel adds about 400 bytes to the
lzma compressed kernel for brcm47xx.

This is copied from a more recent backports version to add the
dev_coredumpm() function when the internal core devdump is not used.

61cfc8075b mac80211: rt2x00: add incomplete support for external PA on MT7620
Do as the vendor driver does -- however, some devices apparently
patched support for external PA into the driver similar to how it was
done on Rt3352, using EEPROM_NIC_CONF1 rather than EEPROM_NIC_CONF2,
hence we check for both fields. Somehow the vendor driver also no
longer offers the option of only one of the TX paths having an external
PA (which was probably to weird to ever be implemented in practise,
though it doesn't seem like a particularly bad idea to me). Do the same
in rt2x00 and enable support for external PA on both TX paths whenever
it is set for TX0 in EEPROM.

c69a89fe23 mac80211: ath10k: allow failure getting board id via otp
ath10k tries to fetch board id via otp, but that fails for many chips
like QCA988x, QCA9984 etc. Recent commit cc189c0b7f removed the earlier
hack that had allowed QCA radios to work, as that hack was incompatible
with the new wifi chips being introduced to the source tree.

Restore functionality for the existing wifi chips by modifying the
return value of the 'board id via otp' function to a value that is recognised
as a harmless error, so that name evaluation continues by using the board file.

Patch originally suggested by Christian Lamparter in forum discussion.

09ae540cd4 ath9k: fix power limits on init
The tx power applied by set_txpower is limited by the CTL (conformance
test limit) entries in the EEPROM. These can change based on the user
configured regulatory domain.
Depending on the EEPROM data this can cause the tx power to become too
limited, if the original regdomain CTLs impose lowr limits than the CTLs
of the user configured regdomain.

To fix this issue, set the initial channel limits without any CTL
restrictions and only apply the CTL at run time when setting the channel
and the real tx power.

181bc02d2e rt2x00: mt7620: yet another beauty session
So here is another round of improvements for MT7620 WiFi.

This commit fixes a few significant issues related to TX_PWR_CFG_x and
TX_ALC and also makes the code more readable by adding register
descriptions for things added for MT7620 and use the usual bit-field
access macros and the now defined macros instead of plain bit-ops and
magic numbers.

Properly describe EEPROM_TARGET_POWER at word 0x68 (== byte 0xD0) and
thereby fix internal TXALC which would otherwise just read
out-of-bounds of the EEPROM map.

Split-out tx-power/ALC related stuff into an additional function.
Fix VCO calibration, it was carried out properly in the channel
switching but incomplete in the actual VCO calibration function.
Also there is no need to trigger VCO calibration in channel switching,
the VCO calibration function is already being called at this point.
Remove it from channel switching function to avoid redundant code.

The TX power calibration differs significantly from all other
Mediatek/Ralink chips: They finally allow 0.5dB steps stored as 8-bit
values for (almost) each bitrate -- and promptly ran out of space and
for some reason didn't want to change the EEPROM layout. The hence
opted for a scheme of sharing values for some adjecent bitrates and
a highly over-complicated (or obfuscated?) way to populate the
TX_PWR_CFG_x registers with the values stored in the EEPROM.
The code here now looks much less complicated than what you see in the
vendor's driver, however, it does the exact same thing:
bGpwrdeltaMinus is a constant and always TRUE, hence half of the
code was dead. Gpwrdelta is always 0 (rather than using the value read
from the EEPROM). What remains is some very grotesque effort to avoid
0x20, probably some hardware bug related to some misunderstanding of
what a singed 8-bit value is (imagine: if it was a signed 6-bit value
then someone could believe that 0x20 == 0x0). And then they didn't
clean it up once they later on anandonned that whole story of having a
constant offset for 40 MHz channels and just set the offset to be
constant 0 -- there is no effort for avoiding 0x20 for the 20 MHz
values stored in the EEPROM, hence that's probably just a forbidden
value in the EEPROM specs and won't appear anyway...
Anyway, the whole thing felt like solving some college math test
where in the end everything cancels out and the result equals 0 ;)
To make sure that channel bandwidth power compensation really doesn't
need to be taken care of, output a warning when the corresponding
value stored in the EEPROM is non-zero.

Also there is no apparent reason to refrain from initializing RFCSR
register 13, it doesn't fail what-so-ever.

9eacb9d7fc rt2x00: mt7620: lots of improvements
This commit combines all the changes I've made on my staging tree
into a single commit fixing many issues with our patch for MT7620.

First of all, checkpatch.pl revealed numerous code style issues with
the patch, so fix all the white-space and commets. Also use
usleep_range instead of legacy timing and relax timing for VCO
calibration just like the vendor driver does.

Several line programming registers were commented out in the patch.
Originally this came from the features present but disabled by default
in the vendor's driver (RTMP_TEMPERATURE_CALIBRATION and
ADJUST_POWER_CONSUMPTION_SUPPORT). Remove the dead code for now, it can
easily be re-added if we actually intend to support those features.

Move values from mt7620_freqconfig type into the existing rf_channel
struct, this shouldn't be a new typedef and it is possible to use the
existing struct because rf_channel got 4 32-bit fields, so two of the
8-bit values from mt7620_freqconfig can easily be stored in the same
32-bit field.

Map values such that
Rdiv -> rf1
N    -> rf2
K    -> rf3[0:7]
D    -> rf3[8:15]
Ksd  -> rf4

This makes the channel switching logic already look a bit more like
what we are used to in rt2x00... Probably many of the read-modify-write
calls could still be replaced by macros intended for that.

iq calibration seems to be identical to RT5592, so just enable it.
Test shows that this improves things quite a lot, datarates went up
by a couple of megabits when running iperf, signal quality seems jumpy
in the first few seconds once a station connencts, the stabelizes on a
value significantly better than what it was before.

Add description to the patch and reference the original OpenWrt commit
by which it was added.

The patch now passes checkpatch.pl and can thus be discussed with the
upstream authors of the rt2x00 driver.
