Instead of using feature flags, add new 32 bit variable for managing different WMI versions. This makes it firmware interface tests a bit less convoluted, especially when we add one more interface. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

It's easier to manage firmware version differences when we configure them in one place. Rename ath10k_core_init_max_sta_count() to ath10k_core_init_firmware_features() and start moving most of the firmware version ("features") handling to that function.

This patch adds support for reading calibration data from Device Tree. It looks for the calibration data in Device Tree if it can't find it in a file. If there's no node in Device Tree, ath10k will try to find the calibration data from OTP. The node for the calibration data should be defined like this: pci { pcie@0 { reg = <0 0 0 0 0>; #interrupt-cells = <1>; #size-cells = <2>; #address-cells = <3>; device_type = "pci"; ath10k@0,0 { reg = <0 0 0 0 0>; device_type = "pci"; qcom,ath10k-calibration-data = [ 01 02 03 ... ]; }; }; }; Signed-off-by: Toshi Kikuchi <toshik@chromium.org> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

If card reset with firmware download executed, followed by reset with use of firmware from build in flash, firmware download indication remains in the hardware register. When running firmware download flow, the SW download indication is written by the driver to bit 0 in usage_6: wil_fw_load(), "S(RGF_USER_USAGE_6, 1);" This register, like all USER RGF, wasn't reset in SW reset flow. Therefore the driver must clear it on SW reset flow. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

In the wil_tx_ring, error message printed when tx attempted while vring has no space to accommodate all fragments of frame. Normally, such situation handled by stopping tx queue. But, if tx queue is by-passed (like pktgen does), this error will be triggered at high rate and dmesg will be flooded with this message. Whole system may become unstable and hang with no possible recover except power cycle. Rate-limit it to prevent dmesg flooding.

Allow to configure VRING size for both Rx and Tx via module parameters: rx_ring_order and tx_ring_order. Parameters are ring size orders, i.e. ring size calculated as 1 << order.

There is no need to obtain physical device through wil->pdev->dev path, as it is done by this macro. The same device already stored as wiphy's device, thus wil_to_dev() returns the same device as wil_to_pcie_dev() Remove unnecessary macros, this allows to drop dependency by pci.h in the firmware download code.

Scan timeout treated as indication for firmware error; and should be handled in the same way. Recovery state machine does not perform as designed because its state is not updated in case of scan timeout. Fix is to set recovery state machine into the proper state.

Like with ath9k, ath5k queues also need to be ordered by priority. queue_info->tqi_subtype already contains the correct index, so use it instead of relying on the order of ath5k_hw_setup_tx_queue calls.

The driver passes the desired hardware queue index for a WMM data queue in qinfo->tqi_subtype. This was ignored in ath9k_hw_setuptxqueue, which instead relied on the order in which the function is called.

This reverts commit 2ad69ac5. It causes wireless device disappear when we get -EPROTO error form USB request. I encounter such situation occasionally when resume form suspend with RT3070 adapter: [ 289.619985] ieee80211 phy0: rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0404 with error -71 [ 289.639368] ieee80211 phy0: rt2800_wait_bbp_ready: Error - BBP register access failed, aborting [ 289.639374] ieee80211 phy0: rt2800usb_set_device_state: Error - Device failed to enter state 4 (-5) Without the patch, except printing error, device works just fine after resume. Currently after timeouts and REGISTER_BUSY_COUNT tuning, we should not have any "endless loop", though we can wait quite long when driver is trying to communicate with the device through non functioning USB connection. Generally the problem that commit 2ad69ac5 solves is kinda artificial. Cc: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.

Currently implemented temperature compensation is only valid on some of supported chips. Other chips do not need temperature compensation or need different way to do this (not yet implemented in the rt2800 driver). Trying to do run rt2800_get_gain_calibration_delta() when this is not appropriate on particular chip gives bogus result of TX power and can make connection unstable. This is follow up to commit 8c8d2017 "rt2800: fix RT5390 & RT3290 TX power settings regression". On that commit we avoid setting BBP_R1 register, but the real problem is wrong temperature compensation calculation.
