2020-03-11ath10k: avoid consecutive OTP download to reduce boot timeVikas Patel
Currently, OTP is downloaded twice in case of "pre-cal-dt" and "pre-cal-file" to fetch the board ID and takes around ~2 sec more boot uptime. First OTP download happens in "ath10k_core_probe_fw" and second in ath10k_core_start. First boot does not need OTP download in core start when valid board id acquired. The second OTP download is required upon core stop/start. This patch skips the OTP download when first OTP download has acquired a valid board id. This patch also marks board id invalid in "ath10k_core_stop", which will force the OTP download in ath10k_core_start and fetches valid board id.

2020-02-14mac80211: Fix setting txpower to zeroBen Greear
With multiple VIFS ath10k, and probably others, tries to find the minimum txpower for all vifs and uses that when setting txpower in the firmware. If a second vif is added and starts to scan, it's txpower is not initialized yet and it set to zero. ath10k had a patch to ignore zero values, but then it is impossible to actually set txpower to zero. So, instead initialize the txpower to INT_MIN in mac80211, and let drivers know that means the power has not been set and so should be ignored. This should fix regression in: commit 88407beb1b1462f706a1950a355fd086e1c450b6 Author: Ryan Hsu <ryanhsu@qca.qualcomm.com> Date: Tue Dec 13 14:55:19 2016 -0800 ath10k: fix incorrect txpower set by P2P_DEVICE interface Tested on ath10k 9984 with ath10k-ct firmware.

BTCOEX feature is not supported by all QCA4019 chipsets. Since btcoex enabled by default in firmware, host needs to enable COEX support depends on the hardware. Enabling it by default in unsupported hardware will cause some feature disabled in hardware. This patch will read btcoex_support flag and wlan priority gpio pin number from DT. Depends on the btcoex_support flag value host will expose BTCOEX support and wlan priority gpio pin number to target.

2020-01-26Revert "ath10k: fix DMA related firmware crashes on multiple devices"Zhi Chen
This reverts commit 76d164f582150fd0259ec0fcbc485470bcd8033e. PCIe hung issue was observed on multiple platforms. The issue was reproduced when DUT was configured as AP and associated with 50+ STAs. For QCA9984/QCA9888, the DMA_BURST_SIZE register controls the AXI burst size of the RD/WR access to the HOST MEM. 0 - No split , RAW read/write transfer size from MAC is put out on bus as burst length 1 - Split at 256 byte boundary 2,3 - Reserved With PCIe protocol analyzer, we can see DMA Read crossing 4KB boundary when issue happened. It broke PCIe spec and caused PCIe stuck. So revert the default value from 0 to 1.

Then when the next RX arrive, the left 30 bytes will be considered as the header of the read, the top 8 bytes will be considered as ath10k_htc_hdr, but actually the 8 bytes is not the ath10k_htc_hdr, so the act_len from this ath10k_htc_hdr is not correct, if it is a big value, such as 57013, it will trigger skb_panic. Drop the skb with invalid length will be reasonable. This patch only effect sdio chips. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

2019-12-13mac80211: Turn AQL into an NL80211_EXT_FEATUREToke Høiland-Jørgensen
Instead of just having an airtime flag in debugfs, turn AQL into a proper NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so we also expose the presence of the feature to userspace. This also has the effect of flipping the default, so drivers have to opt in to using AQL instead of getting it by default with TXQs. To keep functionality the same as pre-patch, we set this feature for ath10k (which is where it is needed the most). While we're at it, split out the debugfs interface so AQL gets its own per-station debugfs file instead of using the 'airtime' file. [Johannes:] This effectively disables AQL for iwlwifi, where it fixes a number of issues: * TSO in iwlwifi is causing underflows and associated warnings in AQL * HE (802.11ax) rates aren't reported properly so at HE rates, AQL could never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

For max bundle size 32, the bundle mask is not same with 8/16. Change it to match the max bundle size of htc. Otherwise it will not match with firmware, for example, when bundle count is 17, then flags of ath10k_htc_hdr is 0x4, if without this patch, it will be considered as non-bundled packet because it does not have mask 0xF0, then trigger error message later: payload length 56747 exceeds max htc length: 4088. htc->max_msgs_per_htc_bundle is the min value of HTC_HOST_MAX_MSG_PER_RX_BUNDLE and msg->ready_ext.max_msgs_per_htc_bundle of ath10k_htc_wait_target, it will be sent to firmware later in ath10k_htc_start, then firmware will use it as the final max rx bundle count, in WLAN.RMH.4.4.1-00029, msg->ready_ext.max_msgs_per_htc_bundle is 32, it is same with HTC_HOST_MAX_MSG_PER_RX_BUNDLE, so the final max rx bundle count will be set to 32 in firmware.

2019-12-02ath10k: enable napi on RX path for sdioWen Gong
For tcp RX, the quantity of tcp acks to remote is 1/2 of the quantity of tcp data from remote, then it will have many small length packets on TX path of sdio bus, then it reduce the RX packets's bandwidth of tcp. This patch enable napi on RX path, then the RX packet of tcp will not feed to tcp stack immeditely from mac80211 since GRO is enabled by default, it will feed to tcp stack after napi complete, if rx bundle is enabled, then it will feed to tcp stack one time for each bundle of RX. For example, RX bundle size is 32, then tcp stack will receive one large length packet, its length is neary 1500*32, then tcp stack will send a tcp ack for this large packet, this will reduce the tcp acks ratio from 1/2 to 1/32. This results in significant performance improvement for tcp RX. Tcp rx throughout is 240Mbps without this patch, and it arrive 390Mbps with this patch.

2019-11-29ath10k: set WMI_PEER_AUTHORIZE after a firmware crashWen Gong
After the firmware crashes ath10k recovers via ieee80211_reconfig(), which eventually leads to firmware configuration and including the encryption keys. However, because there is no new auth/assoc and 4-way-handshake, and firmware set the authorize flag after 4-way-handshake, so the authorize flag in firmware is not set in firmware without 4-way-handshake. This will lead to a failure of data transmission after recovery done when using encrypted connections like WPA-PSK. Set authorize flag after installing keys to firmware will fix the issue. This was noticed by testing firmware crashing using simulate_fw_crash debugfs file. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-1.

2019-11-27ftrace: Rework event_create_dir()Peter Zijlstra
Rework event_create_dir() to use an array of static data instead of function pointers where possible. The problem is that it would call the function pointer on module load before parse_args(), possibly even before jump_labels were initialized. Luckily the generated functions don't use jump_labels but it still seems fragile. It also gets in the way of changing when we make the module map executable. The generated function are basically calling trace_define_field() with a bunch of static arguments. So instead of a function, capture these arguments in a static array, avoiding the function call. Now there are a number of cases where the fields are dynamic (syscall arguments, kprobes and uprobes), in which case a static array does not work, for these we preserve the function call. Luckily all these cases are not related to modules and so we can retain the function call for them. Also fix up all broken tracepoint definitions that now generate a compile error.

2019-11-25ath10k: Handle "invalid" BDFs for msm8998 devicesJeffrey Hugo
When the BDF download QMI message has the end field set to 1, it signals the end of the transfer, and triggers the firmware to do a CRC check. The BDFs for msm8998 devices fail this check, yet the firmware is happy to still use the BDF. It appears that this error is not caught by the downstream drive by concidence, therefore there are production devices in the field where this issue needs to be handled otherwise we cannot support wifi on them.
