When testmode can be enabled, the start() callback would already be called, causing that txpower sku feature isn't really disabled after testmode is enabled. This patch fix the issue. Signed-off-by:

This is a preliminary patch to simplify setting state in mt7915 testmode, for adding the new continuous tx state. Signed-off-by:

Shayne Chen authored
Support to set a special tx state in testmode: continuous tx, which is used for sending tx without time gap. Note that continuous tx mode doesn't send real packets, instead, it's pure phy signal, and the waveform can be observed by instrument. Signed-off-by:

Originally, tx queued limit is set to 1000 to prevent from running out of tx token. If a new testmode tx is triggered while the previous one hasn't finished yet, we'll wait a period of time until tx_done equals to tx_queued. Normally, current queued limit can finish in 10 seconds. However, if ipg is configured to a larger value, less than 1000 packets can be done in the default timeout period, which may lead to a crash when a new testmode tx triggered. To deal with this, make tx queued limit dynamically adjusted according to ipg value. Signed-off-by:

Add spatial extension (spe) index as a configurable parameter in testmode. This is used for specifically configuring TX path, such as different WF TX priority, number of antennas and spatial streams. If spe_idx is not set, TX path depends on tx_antenna_mask; otherwise, both spe_idx and tx_antenna_mask are referenced to decide TX path. Signed-off-by:

This is a preliminary patch for DBDC and ipg config support in testmode. The wmm_idx of band1 should be configured by this command to make band1 Tx work normally. Also, for setting ipg, FW needs a non-empty bss_info structure to do edca parameters update. Signed-off-by:

Add support for getting rf values from flash. This is used for some test purposes and products. If the mtd partition is configured in dts, driver will read from flash to init eeprom command; if not, still init it with efuse's values. An example: &slot0 { mt7915@0,0 { reg = <0x0000 0 0 0 0>; device_type = "pci"; mediatek,mtd-eeprom = <&factory 0x0000>; }; }; Acked-by: -

We have already WARN_ON(!qc) for non-QOS frame on txq->sched_retry path, but we continue to process, what makes no sense since tid is not initialized. Non QOS frame should never happen when aggregation is enabled on queue, so do not process that. Patch should fix smatch warning: drivers/net/wireless/intel/iwlegacy/4965-mac.c:2822 il4965_hdl_tx() error: uninitialized symbol 'tid'. Reported-by:

We can currently get a "command execute failure 19" error on beacon loss if the signal is weak: wlcore: Beacon loss detected. roles:0xff wlcore: Connection loss work (role_id: 0). ... wlcore: ERROR command execute failure 19 ... WARNING: CPU: 0 PID: 1552 at drivers/net/wireless/ti/wlcore/main.c:803 ... (wl12xx_queue_recovery_work.part.0 [wlcore]) (wl12xx_cmd_role_start_sta [wlcore]) (wl1271_op_bss_info_changed [wlcore]) (ieee80211_prep_connection [mac80211]) Error 19 is defined as CMD_STATUS_WRONG_NESTING from the wlcore firmware, and seems to mean that the firmware no longer wants to see the quirk handling for WLCORE_QUIRK_START_STA_FAILS done. This quirk got added with commit 18eab430 ("wlcore: workaround start_sta problem in wl12xx fw"), and it seems that this already got fixed in the firmware long time ago back in 2012 as wl18xx never had this quirk in place to start with. As we no longer even support firmware that early, to me it seems that it's safe to just drop WLCORE_QUIRK_START_STA_FAILS to fix the error. Looks like earlier firmware got disabled back in 2013 with commit 0e284c07 ("wl12xx: increase minimum singlerole firmware version required"). If it turns out we still need WLCORE_QUIRK_START_STA_FAILS with any firmware that the driver works with, we can simply revert this patch and add extra checks for firmware version used. With this fix wlcore reconnects properly after a beacon loss. Cc: Raz Bouganim <r-bouganim@ti.com> Signed-off-by:

The LTR mechanism enables PCIE Endpoints to report the service latency requirements and CPU will enter appropriate sleep state to save power based on the LTR value. 8723de provides two registers to config the LTR, and the original setting is too short for CPU to ente sleep state. The patch adjust the LTR setting. Signed-off-by:
