It needs some more work to fully support old/new tools matrix. - Addressed Dave's comment about bool usage in patch "RDS: IB: track and log active side..." v1->v2: Re-aligned indentation in patch 'RDS: mark few internal functions..." Series consist of: - RDMA transport fixes for map failure, listen sequence, handler panic and composite message notification. - Couple of sparse fixes. - Message logging improvements for bind failure, use once mr semantics and connection remote address, active end point. - Performance improvement for RDMA transport by reducing the post send pressure on the queue and spreading the CQ vectors. - Useful statistics for socket send/recv usage and receive cache usage. - Additional RDS CMSG used by application to track the RDS message stages for certain type of traffic to find out latency spots. Can be enabled/disabled per socket. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| * RDS: add receive message trace used by applicationSantosh Shilimkar2017-01-026-3/+109
| | | | | | | | | | | | | | | | | | | | | | | | Socket option to tap receive path latency in various stages in nano seconds. It can be enabled on selective sockets using using SO_RDS_MSG_RXPATH_LATENCY socket option. RDS will return the data to application with RDS_CMSG_RXPATH_LATENCY in defined format. Scope is left to add more trace points for future without need of change in the interface.

| * RDS: IB: fix panic due to handlers running post teardownSantosh Shilimkar2017-01-022-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shutdown code reaping loop takes care of emptying the CQ's before they being destroyed. And once tasklets are killed, the hanlders are not expected to run. But because of core tasklet code issues, tasklet handler could still run even after tasklet_kill, RDS IB shutdown code already reaps the CQs before freeing cq/qp resources so as such the handlers have nothing left to do post shutdown. On other hand any handler running after teardown and trying to access already freed qp/cq resources causes issues Patch fixes this race by makes sure that handlers returns without any action post teardown.

| * RDS: RDMA: Fix the composite message user notificationSantosh Shilimkar2017-01-024-11/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When application sends an RDS RDMA composite message consist of RDMA transfer to be followed up by non RDMA payload, it expect to be notified *only* when the full message gets delivered. RDS RDMA notification doesn't behave this way though. Thanks to Venkat for debug and root casuing the issue where only first part of the message(RDMA) was successfully delivered but remainder payload delivery failed. In that case, application should not be notified with a false positive of message delivery success. Fix this case by making sure the user gets notified only after the full message delivery.

In addition there are three cleanup patches which don't change any functionality, but are needed to align codebase prior accepting other patches. Memory region (MR) in IB can be huge and ODP (on-demand paging) technique allows to use unpinned memory, which can be consumed and released on demand. This allows to applications do not pin down the underlying physical pages of the address space, and save from them need to track the validity of the mappings. Rather, the HCA requests the latest translations from the OS when pages are not present, and the OS invalidates translations which are no longer valid due to either non-present pages or mapping changes. In existing ODP implementation applications is needed to register memory buffers for communication, though registered memory regions need not have valid mappings at registration time. This patch set performs the following steps to expand current ODP implementation: 1. It refactors UMR to support large regions, by introducing generic function to perform HCA translation table modifications. This function supports both atomic and process contexts and is not limited by number of modified entries. This function allows to enable reallocated memory regions of arbitrary size, so adding MR cache buckets to support up to 16GB MRs. 2. It changes page fault event format and refactor page faults logic together with addition of atomic support. 3. It prepares mlx5 core code to support implicit registration with simplified and relaxed semantics. Implicit ODP semantics allows to applications provide special memory key that represents their complete address space. Thus all IO accesses referencing to this key (with proper access rights associated with the key) wouldn't need not register any virtual address range.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable advertising support for channel 169, 5Ghz so that based on the regulatory domain(country code) this channel shall be active for use. For example in countries like India this channel shall be available for use with latest regulatory updates Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
| | * ath10k: Remove passing unused argument for ath10k_mac_txMohammed Shafi Shajakhan2016-12-301-4/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | 'ath10k_mac_tx' does not seems to use the per station table entry pointer 'sta' (struct ieee80211_sta), hence remove passing this unused argument Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
| | * ath10k: ignore configuring the incorrect board_idRyan Hsu2016-12-301-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With command to get board_id from otp, in the case of following boot get otp board id result 0x00000000 board_id 0 chip_id 0 boot using board name 'bus=pci,bmi-chip-id=0,bmi-board-id=0" ... failed to fetch board data for bus=pci,bmi-chip-id=0,bmi-board-id=0 from ath10k/QCA6174/hw3.0/board-2.bin The invalid board_id=0 will be used as index to search in the board-2.bin. Ignore the case with board_id=0, as it means the otp is not carrying the board id information. Signed-off-by: Ryan Hsu <ryanhsu@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
| | * ath10k: recal the txpower when removing interfaceRyan Hsu2016-12-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The txpower is being recalculated when adding interface to make sure txpower won't overshoot the spec, and when removing the interface, the txpower should again to be recalculated to restore the correct value from the active interface list. Following is one of the scenario vdev0 is created as STA and connected: txpower:23 vdev1 is created as P2P_DEVICE for control interface: txpower:0 vdev2 is created as p2p go/gc interface: txpower is 21 So the vdev2@txpower:21 will be set to firmware when vdev2 is created. When we tear down the vdev2, the txpower needs to be recalculated to re-set it to vdev0@txpower:23 as vdev0/vdev1 are the active interface. ath10k_pci mac vdev 0 peer create 8c:fd:f0:01:62:98 ath10k_pci mac vdev_id 0 txpower 23 ... (adding interface) ath10k_pci mac vdev create 2 (add interface) type 1 subtype 3 ath10k_pci mac vdev_id 2 txpower 21 ath10k_pci mac txpower 21 ... (removing interface) ath10k_pci mac vdev 2 delete (remove interface) ath10k_pci vdev 1 txpower 0 ath10k_pci vdev 0 txpower 23 ath10k_pci mac txpower 23 Signed-off-by: Ryan Hsu <ryanhsu@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
| | * ath10k: support dev_coredump for crash dumpArun Khandavalli2016-12-303-3/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever firmware crashes, and both CONFIG_ATH10K_DEBUGFS and CONFIG_ALLOW_DEV_COREDUMP are enabled, dump information about the crash via a devcoredump device. Dump can be read from userspace for further analysis from: /sys/class/devcoredump/devcd*/data As until now we have provided the firmware crash dump file via fw_crash_dump debugfs keep it still available but deprecate and a warning print that the user should switch to using dev_coredump. Future improvement would be not to depend on CONFIG_ATH10K_DEBUGFS, as there might be systems which want to get the firmware crash dump but not enable debugfs. How to handle memory consumption is also something which needs to be taken into account.
