2020-02-14mt76: Introduce mt76_mcu data structureLorenzo Bianconi1-0/+4
Introduce mt76_mcu data structure to contain common fields between mt76u_mcu and mt76e_mcu. Initialize mcu common fields in mt76_alloc_device(). Rely on mt76_mcu in mt76_mcu_rx_event and in mt76_mcu_get_response in order to reuse them in usb code Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-02-14mt76: introduce struct mt76_phyFelix Fietkau1-0/+5
This is preparation for supporting multiple wiphys per device to support the concurrent dual-band feature of MT7615D On the first wiphy, hw->priv will point to struct mt76_dev, which contains a struct mt76_phy at the start. For the secondary wiphy, hw->priv will point to a mt76_phy encapsulated in a driver specific struct To simplify access to struct mt76_phy members from drivers, the driver specific device struct is changed to add a union of struct mt76_dev and struct mt76_phy as the first element Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-12-18mt76: fix LED link time failureArnd Bergmann1-1/+2
The mt76_led_cleanup() function is called unconditionally, which leads to a link error when CONFIG_LEDS is a loadable module or disabled but mt76 is built-in: drivers/net/wireless/mediatek/mt76/mac80211.o: In function `mt76_unregister_device': mac80211.c:(.text+0x2ac): undefined reference to `led_classdev_unregister' Use the same trick that is guarding the registration, using an IS_ENABLED() check for the CONFIG_MT76_LEDS symbol that indicates whether LEDs can be used or not.

2019-11-20mt76: move interface_modes definition in mt76_core moduleLorenzo Bianconi1-0/+7

2019-11-20mt76: refactor cc_lock locking schemeLorenzo Bianconi1-13/+16
Read busy counters not holding cc_lock spinlock since usb read can't be performed in interrupt context. Move cc_active and cc_rx counters out of cc_lock since they are not modified in interrupt context. Grab cc_lock updating cur_cc_bss_rx in mt76_airtime_report and do not hold rx_lock in mt76_update_survey. Moreover grab mt76 mutex in mt76_get_survey before running mt76_update_survey.

2019-05-01mt76usb: fix tx/rx stopStanislaw Gruszka1-1/+2
Disabling tasklets on stopping rx/tx is wrong. If blocked tasklet is scheduled and we remove device we will get 100% cpu usage: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 9 root 20 0 0 0 0 R 93.8 0.0 1:47.19 ksoftirqd/0 by infinite loop in tasklet_action_common() and eventuall crash on next mt76usb module load: [ 2068.591964] RIP: 0010:tasklet_action_common.isra.17+0x66/0x100 [ 2068.591966] Code: 41 89 f5 eb 25 f0 48 0f ba 33 00 0f 83 b1 00 00 00 48 8b 7a 20 48 8b 42 18 e8 56 a3 b5 00 f0 80 23 fd 48 89 ea 48 85 ed 74 53 <48> 8b 2a 48 8d 5a 08 f0 48 0f ba 6a 08 01 72 0b 8b 42 10 85 c0 74 [ 2068.591968] RSP: 0018:ffff98758c34be58 EFLAGS: 00010206 [ 2068.591969] RAX: ffff98758e6966d0 RBX: ffff98756e69aef8 RCX: 0000000000000006 [ 2068.591970] RDX: 01060a053d060305 RSI: 0000000000000006 RDI: ffff98758e6966d0 [ 2068.591971] RBP: 01060a053d060305 R08: 0000000000000000 R09: 00000000000203c0 [ 2068.591971] R10: 000003ff65b34f08 R11: 0000000000000001 R12: ffff98758e6966d0 [ 2068.591972] R13: 0000000000000006 R14: 0000000000000040 R15: 0000000000000006 [ 2068.591974] FS: 0000000000000000(0000) GS:ffff98758e680000(0000) knlGS:0000000000000000 [ 2068.591975] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 2068.591975] CR2: 00002c5f73a6cc20 CR3: 00000002f920a001 CR4: 00000000003606e0 [ 2068.591977] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 2068.591978] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 2068.591978] Call Trace: [ 2068.591985] __do_softirq+0xe3/0x30a [ 2068.591989] ? sort_range+0x20/0x20 [ 2068.591990] run_ksoftirqd+0x26/0x40 [ 2068.591992] smpboot_thread_fn+0xc5/0x160 [ 2068.591995] kthread+0x112/0x130 [ 2068.591997] ? kthread_create_on_node+0x40/0x40 [ 2068.591998] ret_from_fork+0x35/0x40 [ 2068.591999] Modules linked in: ccm arc4 fuse rfcomm cmac bnep sunrpc snd_hda_codec_hdmi snd_soc_skl snd_soc_core snd_soc_acpi_intel_match snd_hda_codec_realtek snd_soc_acpi snd_hda_codec_generic snd_soc_skl_ipc snd_soc_sst_ipc snd_soc_sst_dsp snd_hda_ext_core iTCO_wdt snd_hda_intel intel_rapl iTCO_vendor_support x86_pkg_temp_thermal intel_powerclamp btusb mei_wdt coretemp btrtl snd_hda_codec btbcm btintel intel_cstate snd_hwdep intel_uncore uvcvideo snd_hda_core videobuf2_vmalloc videobuf2_memops intel_rapl_perf wmi_bmof videobuf2_v4l2 intel_wmi_thunderbolt snd_seq bluetooth joydev videobuf2_common snd_seq_device snd_pcm videodev media i2c_i801 snd_timer idma64 ecdh_generic intel_lpss_pci intel_lpss mei_me mei ucsi_acpi typec_ucsi processor_thermal_device intel_soc_dts_iosf intel_pch_thermal typec thinkpad_acpi wmi snd soundcore rfkill int3403_thermal int340x_thermal_zone int3400_thermal acpi_thermal_rel acpi_pad pcc_cpufreq uas usb_storage crc32c_intel i915 i2c_algo_bit nvme serio_raw [ 2068.592033] drm_kms_helper e1000e nvme_core drm video ipv6 [last unloaded: cfg80211] Fortunate thing is that this not happen frequently, as scheduling tasklet on blocked state is very exceptional, though might happen. Due to different RX/TX tasklet processing fix is different for those. For RX we have to assure rx_tasklet do fail to resubmit buffers by poisoning urb's and kill the tasklet. For TX we need to handle all stop cases properly (suspend, module unload, device removal). Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-05-01mt76: fix tx power issuesFelix Fietkau1-1/+1
- tx power is stored in the channels after ieee80211_register_hw, so chan->orig_mpwr needs to be updated as well - for non-TSSI devices, mt76x2e needs to use a different target power value from the EEPROM - fix a rounding error in a few places (need to round up, not down) Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76: introduce mt76_free_device routineLorenzo Bianconi1-1/+7
Move mt76_tx_free in mt76_free_device routine in order to unmap all txwi descriptors at module unload Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76: unify set_timStanislaw Gruszka1-0/+7
All mt76 drivers (now also USB drivers) require empty .set_tim callback. Add it to common mt76 module and use on all drivers. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
