ath9k: support DT ieee80211-freq-limit property to limit channels The common DT property can be used to limit the available channels but ath9k has to manually call wiphy_read_of_freq_limits(). I would have put this into ath9k_of_init(). But it didn't work there. The reason is that in ath9k_of_init() the channels and bands are not yet registered in the wiphy struct. So there isn't any channel to flag as disabled.

ath9k: fetch calibration data via nvmem subsystem On most embedded ath9k devices (like range extenders, routers, accesspoints, ...) the calibration data is stored in a MTD partitions named "ART", or "caldata"/ "calibration". Since commit 4b361cfa8624 ("mtd: core: add OTP nvmem provider support"): All MTD partitions are all automatically available through the nvmem subsystem. This feature - together with an nvmem cell definition either in the platform data or via device-tree allows drivers to get the data necessary for initializing the WIFI, without having to wait around for the filesystem and userspace to do the extractions.

of: net: pass the dst buffer to of_get_mac_address() of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.

ath9k: Differentiate between max combined and per chain power The ath9k driver uses as maximum allowed txpower the constant MAX_RATE_POWER. It is used to set a maximum txpower limit for the PHY (which is combined txpower) and also the maximum txpower for per chain rates. Its value 63 is derived from the maximum number the registers can store for the per chain txpower. The max txpower a user can set because of this is 31 dBm (floor(63 / 2)). This also means that a device with multiple tx chains is even limited further: * 1 chain: 31 dBm per chain * 2 chains: 28 dBm per chain * 3 chains: 26 dBm per chain This combined txpower limit of 31 dBm becomes even more problematic when some extra antenna gain is set in the EEPROM. A high power device is then no longer able to reach its potential limits. Instead the code dealing with the combined txpower must use a higher limit than 63 and only the code dealing with the per chain txpower have to use the limit of 63. Since the antenna gain can be quite large and 8 bit variables are often used in ath9k for txpower, a large, divisible by two number like 254 is a good choice for this new limit.

ath9k: Avoid OF no-EEPROM quirks without qca,no-eeprom ath9k_of_init() function[0] was initially written on the assumption that if someone had an explicit ath9k OF node that "there must be something wrong, why would someone add an OF node if everything is fine"[1] (Quoting Martin Blumenstingl <martin.blumenstingl@googlemail.com>) "it turns out it's not that simple. with your requirements I'm now aware of two use-cases where the current code in ath9k_of_init() doesn't work without modifications"[1] The "your requirements" Martin speaks of is the result of the fact that I have a device (PowerCloud Systems CR5000) has some kind of default - not unique mac address - set and requires to set the correct MAC address via mac-address devicetree property, however: "some cards come with a physical EEPROM chip [or OTP] so "qca,no-eeprom" should not be set (your use-case). in this case AH_USE_EEPROM should be set (which is the default when there is no OF node)"[1] The other use case is: the firmware on some PowerMac G5 seems to add a OF node for the ath9k card automatically. depending on the EEPROM on the card AH_NO_EEP_SWAP should be unset (which is the default when there is no OF node). see [3] After this patch to ath9k_of_init() the new behavior will be: if there's no OF node then everything is the same as before if there's an empty OF node then ath9k will use the hardware EEPROM (before ath9k would fail to initialize because no EEPROM data was provided by userspace) if there's an OF node with only a MAC address then ath9k will use the MAC address and the hardware EEPROM (see the case above) with "qca,no-eeprom" EEPROM data from userspace will be requested. the behavior here will not change [1] Martin provides additional background on EEPROM swapping[1].

ath9k: fix race condition in enabling/disabling IRQs The code currently relies on refcounting to disable IRQs from within the IRQ handler and re-enabling them again after the tasklet has run. However, due to race conditions sometimes the IRQ handler might be called twice, or the tasklet may not run at all (if interrupted in the middle of a reset). This can cause nasty imbalances in the irq-disable refcount which will get the driver permanently stuck until the entire radio has been stopped and started again (ath_reset will not recover from this). Instead of using this fragile logic, change the code to ensure that running the irq handler during tasklet processing is safe, and leave the refcount untouched.

ath9k: Introduce airtime fairness scheduling between stations This reworks the ath9k driver to schedule transmissions to connected stations in a way that enforces airtime fairness between them. It accomplishes this by measuring the time spent transmitting to or receiving from a station at TX and RX completion, and accounting this to a per-station, per-QoS level airtime deficit. Then, an FQ-CoDel based deficit scheduler is employed at packet dequeue time, to control which station gets the next transmission opportunity. Airtime fairness can significantly improve the efficiency of the network when station rates vary. The following throughput values are from a simple three-station test scenario, where two stations operate at the highest HT20 rate, and one station at the lowest, and the scheduler is employed at the access point: Before / After Fast station 1: 19.17 / 25.09 Mbps Fast station 2: 19.83 / 25.21 Mbps Slow station: 2.58 / 1.77 Mbps Total: 41.58 / 52.07 Mbps The benefit of airtime fairness goes up the more stations are present. In a 30-station test with one station artificially limited to 1 Mbps, we have seen aggregate throughput go from 2.14 to 17.76 Mbps.

ath9k: Switch to using mac80211 intermediate software queues. This switches ath9k over to using the mac80211 intermediate software queueing mechanism for data packets. It removes the queueing inside the driver, except for the retry queue, and instead pulls from mac80211 when a packet is needed. The retry queue is used to store a packet that was pulled but can't be sent immediately. The old code path in ath_tx_start that would queue packets has been removed completely, as has the qlen limit tunables (since there's no longer a queue in the driver to limit). The mac80211 intermediate software queues offer significant latency reductions, and this patch allows ath9k to realise them. The exact gains from this varies with the test scenario, but in an access point scenario we have seen latency reductions ranging from 1/3 to as much as an order of magnitude. We also achieve slightly better aggregation. Median latency (ping) figures with this patch applied at the access point, with two high-rate stations and one low-rate station (HT20 5Ghz), running a Flent rtt_fair_var_up test with one TCP flow and one ping flow going to each station: Fast station Slow station Default pfifo_fast qdisc: 430.4 ms 638.7 ms fq_codel qdisc on iface: 35.5 ms 211.8 ms This patch set: 22.4 ms 38.2 ms Median aggregation sizes over the same test: Default pfifo_fast qdisc: 9.5 pkts 1.9 pkts fq_codel qdisc on iface: 11.2 pkts 1.9 pkts This patch set: 13.9 pkts 1.9 pkts This patch is based on Tim's original patch set, but reworked quite thoroughly.

wireless: deprecate WDS and disable by default The old WDS 4-addr frame support is very limited, e.g. * no encryption is possible on such links * it cannot support rate/HT/VHT negotiation * management APIs are very restricted These make the WDS legacy mode useless in practice. All of these are resolved by the 4-addr AP/client support, so there's also no reason to improve WDS in the future. Therefore, add a Kconfig option to disable legacy WDS. This gives people an "emergency valve" while they migrate to the better-supported 4-addr AP/client option; we plan to remove it (and the associated cfg80211/mac80211 code, which is the ultimate goal) in the future.

tree-wide: replace config_enabled() with IS_ENABLED() The use of config_enabled() against config options is ambiguous. In practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the author might have used it for the meaning of IS_ENABLED(). Using IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention clearer. This commit replaces config_enabled() with IS_ENABLED() where possible. This commit is only touching bool config options. I noticed two cases where config_enabled() is used against a tristate option: - config_enabled(CONFIG_HWMON) [ drivers/net/wireless/ath/ath10k/thermal.c ] - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE) [ drivers/gpu/drm/gma500/opregion.c ] I did not touch them because they should be converted to IS_BUILTIN() in order to keep the logic, but I was not sure it was the authors' intention.

mac80211: convert HW flags to unsigned long bitmap As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

ath9k: Remove ath9k rate control There is no benefit in retaining the legacy rate control module in the driver codebase. It is known to be buggy and has less than optimal performance in real-world environments compared with minstrel. The only reason that it was kept when we made the switch to minstrel as default was that it showed higher throughput numbers in a clean/ideal environment. This is no longer the case and minstrel can push ath9k to the same throughput levels. In TCP, with 3-stream cards, more than 295 Mbps can be obtained in open air, with 2-stream cards, 210 Mbps is easily reached. To test performance issues, instead of using a broken rate control module, it is better to use the fixed-rate interface provided by mac80211 anyway. The ath9k RC has not received any bug fixes in years and is just bit-rotting away - this patch removes it. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

ath9k: Use a separate TX gain table for WZR-HP-G450H The Buffalo device WZR-HP-G450H uses the index 3 for TX gain, which is set to the high_power table currently. Later variants of the router use the same index, but instead refer to the low_ob_db gain table. This is not handled in the driver since there is no way to distinguish board revisions and the high_power table is used (incorrectly) for the newer variants. By default, devices based on AR9300 using the TX gain index 3 have to use the high_power table. To make sure that WZR-HP-G450H is not broken when the high_power table is updated, use a separate array based on information obtained from the platform data. The current situation where only the original variant of WZR-HP-G450H works properly stays unchanged. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

The RF exposure limits used are expressed in the terms of SAR, which is a measure of the electric and magnetic field strength and power density for transmitters operating at frequencies from 300 kHz to 100 GHz. Regulatory bodies around the world require that wireless device be evaluated to meet the RF exposure limits set forth in the governmental SAR regulations.

Reports of DMA problems are still trickling in and are sitting in the kernel bugzilla. Until the PS code in ath9k is given a thorough review, disbale it by default. The slight increase in chip power consumption is a small price to pay for improved link stability.

ath9k: add spectral scan feature Adds the spectral scan feature for ath9k. AR92xx and AR93xx chips are supported for now. The spectral scan is triggered by configuring a mode through a debugfs control file. Samples can be gathered via another relay debugfs file. Essentially, to try it out: echo chanscan > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl iw dev wlan0 scan cat /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan0 > samples echo disable > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl This feature is still experimental. The special "chanscan" mode is used to perform spectral scan while mac80211 is scanning for channels. To allow this, sw_scan_start/complete() ops have been added. The patch contains code snippets and information from Zefir Kurtisi and information provided by Adrian Chadd and Felix Fietkau.

ath9k: recover ar9380 chips from rare stuck state In the experiment with Azimuth ADEPT-n testbed where the APs transmit power was reduced to 25% and the signal strength was futher attenuated by 20dB and induced a path loss of ~7dB, the station was reporting beacon losses and the following issue were observed. * rx clear is stuck at low for more than 300ms * dcu chain and complete state is stuck at one of the hang signature This patch triggers the hang detection logic that recovers the chip from any of the above conditions. As the issue was originally reported in ChromeOs with AR9382 chips, this detection logic is enabled only for AR9380/2 chips.

ath9k: reduce listen time period When we have downlink traffic alone and the station is going thru bgscan, the client is out of operating channel for around 1000ms which is too long. The mac80211 decides when to switch back to oper channel based on tx queue, bad latency and listen time. As the station does not have tx traffic, the bgscan can easily affect downlink throughput. By reducing the listen time, it helps the associated AP to retain the downstream rate.

ath9k_hw: make bluetooth coexistence support optional at compile time Many systems (e.g. embedded systems) do not have wifi modules connected to bluetooth modules, so bluetooth coexistence is irrelevant there. With the addition of MCI support, ath9k picked up quite a bit of extra code that can be compiled out this way. This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for querying the bluetooth coexistence scheme, allowing the compiler to eliminate code that uses it, with only very little use of #ifdef. On MIPS this reduces the total size for the modules by about 20k. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

ath9k: add MAC revision detection for AR9330 The AR9330 1.0 and 1.1 are using the same revision, thus it is not possible to distinguish the two chips. The platform setup code can distinguish the chips based on the SoC revision. Add a callback function to ath9k_platform_data in order to allow getting the revision number from the platform code.

net: remove mm.h inclusion from netdevice.h Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

ath9k: Fix power save usage count imbalance on deinit While unloading the driver, the ps_usecount is incremented before configuring gpio registers in deinit_device. But it is failed to restore the ps_usecount after that. The problem is that the chip is forcibly moved to FULL SLEEP by radio_disable when mac80211 is reporting as idle though ps_usecount is not zero. This patch retores ps_usecount properly and ensures that the chip is always moved to full sleep only if ps usage count is zero which also helps in debugging deadbeef on multivif case. And also fixes the following warning. ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:536 ath_stoprecv+0xf4/0x100 [ath9k]() Cc: stable@kernel.org Cc: Paul Stewart <pstew@google.com> Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

ath9k: Reset keycache on resume It looks like some hardware registers are left into undefined state after suspend/resume. At minimum, this can cause odd issues related to key cache and hardware trying to encrypt/decrypt frames unexpectedly. This seems to happen even when there is no keys configured, i.e., hardware can end up touching TX frames just based of invalid key cache context even if the driver is not asking a specific entry to be used. In addition, RX can likely be affected. This patch fixes this issue.

ath9k: rework tx queue selection and fix queue stopping/waking The current ath9k tx queue handling code showed a few issues that could lead to locking issues, tx stalls due to stopped queues, and maybe even DMA issues. The main source of these issues is that in some places the queue is selected via skb queue mapping in places where this mapping may no longer be valid. One such place is when data frames are transmitted via the CAB queue (for powersave buffered frames). This is made even worse by a lookup WMM AC values from the assigned tx queue (which is undefined for the CAB queue). This messed up the pending frame counting, which in turn caused issues with queues getting stopped, but not woken again. To fix these issues, this patch removes an unnecessary abstraction separating a driver internal queue number from the skb queue number (not to be confused with the hardware queue number). It seems that this abstraction may have been necessary because of tx queue preinitialization from the initvals. This patch avoids breakage here by pushing the software <-> hardware queue mapping to the function that assigns the tx queues and redefining the WMM AC definitions to match the numbers used by mac80211 (also affects ath9k_htc). To ensure consistency wrt. pending frame count tracking, these counters are moved to the ath_txq struct, updated with the txq lock held, but only where the tx queue selected by the skb queue map actually matches the tx queue used by the driver for the frame.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
