* iwm: improve rfkill handlingAndriy Gapon2020-05-201-0/+2
| | | | | | | | | | | | | | Previously the driver handled the bit within itself, but did not expose the state change to net80211 and interface layers. This change uses net80211 KPI for rfkill signaling. The code is modeled after similar code in iwn and wpi.

* iwm(4): Remove _mvm from the namespace.Mark Johnston2019-11-271-6/+6
| | | | | | | | | | | | | This was inherited from iwlwifi, which drives devices supported by both iwn(4) and iwm(4) in FreeBSD. In iwm(4) _mvm is meaningless, so remove it. OpenBSD made the same change a long time ago. No functional change intended. MFC after: 2 weeks Sponsored by: The FreeBSD Foundation Notes: svn path=/head/; revision=355144
* iwm: Implement the new receive path.Mark Johnston2019-11-071-6/+8
| | | | | | | | | | | | | This is the multiqueue receive code required for 9000-series chips. Note that we still only configure a single RX queue for now. Multiqueue support will require MSI-X configuration and a scheme for managing a global pool of RX buffers.

* Fix ieee80211_radiotap(9) usage in wireless drivers:Andriy Voskoboinyk2019-03-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | - Alignment issues: * Add missing __packed attributes + padding across all drivers; in most places there was an assumption that padding will be always minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) - padding was just missing. * Add __aligned(8) attribute for all Rx radiotap headers since they can contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so just drop the attribute here. Refresh ieee80211_radiotap(9) man page accordingly. - Since net80211 automatically updates channel frequency / flags in ieee80211_radiotap_chan_change() drop duplicate setup for these fields in drivers. Tested with Netgear WG111 v3 (urtw(4)), STA mode. MFC after: 2 weeks Notes: svn path=/head/; revision=344990

* iwm - Track firmware state better, and improve handling in iwm_newstate().Kyle Evans2019-01-241-0/+4
| | | | | | | | | | | | | | | | | | | | | * This avoids firmware resets in all the cases in iwm_newstate(). Instead iwm_bring_down_firmware() is called, which tears down all the STA connection state, according to the sc->sc_firmware_state value. * Improve the behaviour of the LED blinking a bit, so it only blinks when there really is a wireless scan going on. * Print the newstate arg in debug output of iwm_newstate(), to help in debugging. This is inspired by the firmware state maintaining change in OpenBSD's iwm, by stsp@openbsd.org (OpenBSD Git 0ddb056fb7370664b1d4b84392697cb17d1a414a).

* if_iwm - Move iwm_read_firmware() call into iwm_attach().Kyle Evans2019-01-241-10/+0
| | | | | | | | | | | | | | | | | | | | | | * We should load the firmware exactly once before the driver really initializes the hardware the first time, and unload it at detach time. There is no need to retrieve the firmware during execution of iwm_mvm_load_ucode_wait_alive(), we should make sure we already have the firmware data at hand before that. * The existing sc_preinit_hook code fails to deal with the case where if_iwm is loaded by the loader (or is statically linked) and the firmware needs to be loaded from disk. So we can just call iwm_read_firmware() from iwm_attach() directly. * A separate solution will have to be added to properly defer the firmware loading during bootup, until the necessary filesystem is mounted.

* if_iwm - Update firmware rs table, instead of indexing the table in tx cmds.Kyle Evans2019-01-241-2/+0
| | | | | | | | | | | | | | | | | | | | | | * Rather than providing a non-zero index into the firmware RS table, we should always use index 0 and update the firmware RS table whenever our chosen tx rate for data-frames changes. * Send IWM_LQ_CMD updates when the tx rate gets updated by the net80211 rate control (which is after we tell the tx status to the net80211 rate-control in iwm_mvm_rx_tx_cmd_single()). * Disregard frames transferred with a different tx rate than the currently selected rate for the rate-control calculations. This way we avoid counting management frames (which are sent at a slow, and fixed rate), as well as frames we added to the tx queue just before a new IWM_LQ_CMD update took effect.

| | | | | | | | | | | | | | * LAR can be disabled with the hw.iwm.lar.disable tunable now. * On Family 8000 devices we need to check the lar_enabled flag from nvm_data in addition to the TLV_CAPA_LAR_SUPPORT flag from the firmware. * Add a separate IWM_DEBUG_LAR debugging flag.

* [iwm] Properly implement iwm_wme_update callback function.Adrian Chadd2017-05-121-0/+13
| | | | | | | | | | | | | | | | | | | | | * Inspired by iwn(4) and Linux iwlwifi. * Read wme parameters into a buffer within struct iwm_vap in iwm_wme_update(). * If we aren't associated yet, the new settings will soon be sent by iwm_mvm_mac_ctxt_changed() during association. * If we are already associated, explicitly call iwm_mvm_mac_ctxt_changed() from iwm_wme_update() to send the new settings to the firmware. * Change iwm_mvm_ac_to_tx_fifo mapping, to fit the freebsd net80211 WME stream class numbering, instead of Linux's enum ieee80211_ac_numbers.

* [iwm] Process multiple frames per RX buffer.Adrian Chadd2017-05-121-1/+0
| | | | | | | | | | | | | | | | | | | | | | | * Factor out iwm_handle_rxb() function from iwm_notif_intr(). * Removing the IWM_FH_RCSR_CHNL0_RX_CONFIG_SINGLE_FRAME_MSK flag allows the device to put multiple frames (both command responses and 80211 frames) into a single RX buffer. * Uses m_copym() to split up the receive buffers when multiple 80211 frames are received in one RX buffer. The effect is basically the same as when using m_split(), but we want to keep the original mbuf around when calling iwm_mvm_rx_rx_mpdu() to make error handling a bit easier for now. * Contains a small optimization to avoid the m_copym() when only a single 80211 frame is received in one RX buffer (i.e. matching the existing behaviour).

* [iwm] Add basic powermanagement support via ifconfig wlan0 powersave.Adrian Chadd2017-05-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * The DEVICE_POWER_FLAGS_CAM_MSK flag was removed in the upstream iwlwifi in Linux commit ceef91c89480dd18bb3ac51e91280a233d0ca41f. * Add sc_ps_disabled flag to struct iwm_softc, which corresponds to mvm->ps_disabled in struct iwl_mvm in Linux iwlwifi. * Adds a hw.iwm.power_scheme tunable which corresponds to the power_scheme module parameter in Linux iwlwifi. Set this to 1 for completely disabling power management, 2 (default) for balanced powermanagement, and 3 for lowerpower mode (which does dtim period skipping). * Imports the constants.h file from iwlwifi as if_iwm_constants.h. * This doesn't allow changing the powermanagement setting while connected, also one can only choose between enabled and disabled powersaving with ifconfig (so switching between balanced and low-power mode requires rebooting to change the tunable). * After any changes to powermanagement (i.e. "ifconfig wlan0 powersave" to enable powermanagement, or "ifconfig wlan0 -powersave" for disabling powermanagement), one has to disconnect and reconnect to the accespoint for the change to take effect.

This should be fine since we always only tell the firmware to do a single scan iteration anyway.

* net80211: ieee80211_ratectl*: switch to reusable KPIAndriy Voskoboinyk2016-10-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace various void * / int argument combinations with common structures: - ieee80211_ratectl_tx_status for *_tx_complete(); - ieee80211_ratectl_tx_stats for *_tx_update(); While here, improve amrr_tx_update() for a bit: 1. In case, if receiver is not known (typical for Ralink USB drivers), refresh Tx rate for all nodes on the interface. 2. There was a misuse: - otus(4) sends non-decreasing counters (as originally intended); - but ural(4), rum(4) and run(4) are using 'read & clear' registers to obtain statistics for some period of time (and those 'last period' values are used as arguments for tx_update()). If arguments are not big enough, they are just discarded after the next call. Fix: move counting into *_tx_update() (now otus(4) will zero out all node counters after every tx_update() call) Tested with: - Intel 3945BG (wpi(4)), STA mode. - WUSB54GC (rum(4)), STA / HOSTAP mode. - RTL8188EU (urtwn(4)), STA mode.

* [iwm] Remove unused field from iwm_rx_data. Use uint32_t instead of enum type.Imre Vadász2016-09-191-1/+0
| | | | | | | | | | | | | | | The wantresp field in struct iwm_rx_data has never been used for anything, so we can just delete it. Apparently struct iwm_sf_cfg_cmd was compiled correctly (using a 32bit value to represent the enum), but it still seems like a very bad idea to use an enum type in a __packed struct.

* [iwm] Fix up busdma use in the RX pathAdrian Chadd2016-06-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | When allocating a new mbuf or bus_dmamap_load()-ing it fails, we can just keep the old mbuf since we are dropping that packet anyway. Instead of doing bus_dmamap_create() and bus_dmamap_destroy() all the time, create an extra bus_dmamap_t which we can use to safely try bus_dmamap_load()-ing the new mbuf. On success we just swap the spare bus_dmamap_t with the data->map of that ring entry. Tested: Tested with Intel AC7260, verified with vmstat -m that new kernel no longer visibly leaks memory from the M_DEVBUF malloc type. Before, leakage was 1KB every few seconds while ping(8)-ing over the wlan connection.
