2019-09-17ath10k: Use standard bulk clock API in snocBjorn Andersson2-115/+21
No frequency is currently specified for the single clock defined in the snoc driver, so the clock wrappers reimplements the standard bulk API provided by the clock framework. Change to this. The single clock defined is marked as optional so this version of the get API is used, but might need to be reconsidered in the future.

2019-09-17ath10k: Use standard regulator bulk API in snocBjorn Andersson2-170/+27
The regulator_get_optional() exists for cases where the driver needs do behave differently depending on some regulator supply being present or not, as we don't use this we can use the standard regulator_get() and rely on its handling of unspecified regulators. While the driver currently doesn't specify any loads the regulator framework was updated last year to only account for load of enabled regulators, so should the need appear it's better to apply load numbers during initialization that dynamically. With this the regulator wrappers have been reduced the become identical to the standard bulk API provided by the regulator framework, so use these instead of rolling our own.

2019-09-17ath10k: snoc: skip regulator operationsBjorn Andersson2-23/+6
The regulator operations is trying to set a voltage to a fixed value, by giving some wiggle room. But some board designs specifies regulator voltages outside this limited range. One such example is the Lenovo Yoga C630, with vdd-3.3-ch0 in particular specified at 3.1V. But consumers with fixed voltage requirements should just rely on the board configuration to provide the power at the required level, so this code should be removed.

2019-09-17ath10k: Fix HOST capability QMI incompatibilityBjorn Andersson5-3/+45
The introduction of 768ec4c012ac ("ath10k: update HOST capability QMI message") served the purpose of supporting the new and extended HOST capability QMI message. But while the new message adds a slew of optional members it changes the data type of the "daemon_support" member, which means that older versions of the firmware will fail to decode the incoming request message. There is no way to detect this breakage from Linux and there's no way to recover from sending the wrong message (i.e. we can't just try one format and then fallback to the other), so a quirk is introduced in DeviceTree to indicate to the driver that the firmware requires the 8bit version of this message.

2019-09-17ath10k: Check if station exists before forwarding tx airtime reportHauke Mehrtens1-1/+1
It looks like the FW on QCA9984 already reports the tx airtimes before the station is added to the peer entry. The peer entry is created in ath10k_peer_map_event() just with the vdev_id and the ethaddr, but not with a station entry, this is added later in ath10k_peer_create() in callbacks from mac80211. When there is no sta added to the peer entry, this function fails because it calls ieee80211_sta_register_airtime() with NULL. This was reported in OpenWrt some time ago: https://bugs.openwrt.org/index.php?do=details&task_id=2414 This commit should fix this crash: [ 75.991714] Unable to handle kernel paging request at virtual

2019-09-12ath10k: fix channel info parsing for non tlv targetRakesh Pillai3-9/+17
The tlv targets such as WCN3990 send more data in the chan info event, which is not sent by the non tlv targets. There is a minimum size check in the wmi event for non-tlv targets and hence we cannot update the common channel info structure as it was done in commit 13104929d2ec ("ath10k: fill the channel survey results for WCN3990 correctly"). This broke channel survey results on 10.x firmware versions. If the common channel info structure is updated, the size check for chan info event for non-tlv targets will fail and return -EPROTO and we see the below error messages ath10k_pci 0000:01:00.0: failed to parse chan info event: -71 Add tlv specific channel info structure and restore the original size of the common channel info structure to mitigate this issue.

2019-09-12ath10k: adjust skb length in ath10k_sdio_mbox_rx_packetNicolas Boichat1-8/+21
When the FW bundles multiple packets, pkt->act_len may be incorrect as it refers to the first packet only (however, the FW will only bundle packets that fit into the same pkt->alloc_len). Before this patch, the skb length would be set (incorrectly) to pkt->act_len in ath10k_sdio_mbox_rx_packet, and then later manually adjusted in ath10k_sdio_mbox_rx_process_packet. The first problem is that ath10k_sdio_mbox_rx_process_packet does not use proper skb_put commands to adjust the length (it directly changes skb->len), so we end up with a mismatch between skb->head + skb->tail and skb->data + skb->len. This is quite serious, and causes corruptions in the TCP stack, as the stack tries to coalesce packets, and relies on skb->tail being correct (that is, skb_tail_pointer must point to the first byte_after_ the data). Instead of re-adjusting the size in ath10k_sdio_mbox_rx_process_packet, this moves the code to ath10k_sdio_mbox_rx_packet, and also add a bounds check, as skb_put would crash the kernel if not enough space is available.

My wave-1 firmware often crashes when I am bringing down AP vdevs, and sometimes at least some machines lockup hard after spewing IOMMU errors. I don't see the same issue in STA mode, so I suspect beacons are the issue. Moving the beacon buf deletion to later in the vdev teardown logic appears to help this problem.

2019-09-10ath10k: add reorder and change PN check logic for mac80211Wen Gong1-2/+89
For sdio chip, if the rssi is not good, then it have some retry, firmware will indicate the msdu list of a ppdu with a hole, it means it lost the hole msdu, after the msdu retry from AP, the hole msdu will indicate from firmware later. The hole msdu's PN check will fail and the hole msdu will be dropped. PN check fail example: Sequence number PN number PN check status 3814 6101 success 3815 6102 success 3816 6103 success 3818 6105 success 3819 6106 success 3820 6107 success 3817 6104 fail The correct logic is reorder the msdu list and then do PN check. ieee80211_rx_reorder_ampdu of mac80211 will do the reorer logic and then do PN check in ieee80211_rx_h_decrypt of mac80211. example after reorder: Sequence number PN number PN check status 3814 6101 success 3815 6102 success 3816 6103 success 3817 6104 success 3818 6105 success 3819 6106 success 3820 6107 success Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWP-1.

2019-06-25ath10k: add support for controlling tx power to a stationAshok Raj Nagarajan3-0/+48
This patch will add the support to control the transmit power for traffic to a station associated with the AP. Underlying firmware will enforce that the maximum tx power will be based on the regulatory requirements. If the user given transmit power is greater than the allowed tx power in the given channel, then the firmware will use the maximum tx power in the same channel. Max and Min tx power values will depends on no of tx chain masks, for QCA9984 allowed tx power range values from 6 to 23. When 0 is sent to the firmware as tx power, it will revert to the default tx power for the station.

So we can't use this command to set ht/vht single rate any more. - Use peer_assoc command This command can update rx capability for multiple rates, it will work fine for ht mcs rates, as each supported mcs can be advertised in ht_mcs index mask. But this will not work with vht rates because, as per the vht mcs capability advertisement, there are only two bits to indicate the supported mcs. E.g. only support 0-7, 0-8, 0-9. So introduced new WMI command: WMI_PEER_PARAM_FIXED_RATE. After peer assoc, the peer fixed rate cmd will work for that specific peer. Remaining peers will use auto rate. If both vdev fixed rate and peer fixed rates are given, peer fixed rate will take effect to peers for which this cmd is given. Remaining peers in that vdev, will use vdev fixed rate.

Good improvement was observed in the receive side performance when call to ath10k_dbg() is avoided in the RX path. Since currently all debug messages are sent via tracing infrastructure, we cannot entirely avoid calling ath10k_dbg.
