* mac80211: add dev_coredumpm() functionHauke Mehrtens2017-09-171-0/+156
| | | | | | | | | | | | | | | | 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. Fixes: a5922f6 ("kernel: bluetooth: add marvell sdio bluetooth module") Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* ath10k: Re-enable intermediate softqueues for all devicesToke Høiland-Jørgensen2017-09-112-2/+29
| | | | | | | | | | | | The upstream ath10k driver disables the intermediate softqueues for some devices. This patch reverts that behaviour and always enables the softqueues (and associated bufferbloat fixes). We have had reports of people running this with good results: https://lists.bufferbloat.net/pipermail/make-wifi-fast/2017-September/001497.html This also refreshes mac80211 patches.

* mac80211: rt2x00: add incomplete support for external PA on MT7620Daniel Golle2017-04-241-0/+125
| | | | | | | | | | | | | | 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. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* mac80211: ath10k: allow failure getting board id via otpHannu Nyman2017-03-281-0/+11
| | | | | | | | | | | | | | | 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. Signed-off-by: Hannu Nyman <hannu.nyman@iki.fi>
* ath9k: fix power limits on initFelix Fietkau2017-03-221-0/+47
| | | | | | | | | | | | | | | 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.

* ath: do not apply broken power limits with ATH_USER_REGDFelix Fietkau2017-03-223-12/+44
| | | | | | | | | If a device uses the default EEPROM code, typically only the main CTLs are valid, and they do not apply properly when switching to a different regulatory domain.

* rt2x00: mt7620: yet another beauty sessionDaniel Golle2017-03-091-171/+524
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
