wifi: wlcore: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. wlcore_remove() returned zero unconditionally. With that converted to return void instead, the wl12xx and wl18xx driver can be converted to .remove_new trivially.

wlcore: Fix command execute failure 19 for wl12xx 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 ...

This quirk got added with commit 18eab430700d ("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 0e284c074ef9 ("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.

wlcore: simplify/fix/optimize reg_ch_conf_pending operations Bitmaps are defined on unsigned longs, so the usage of u32[2] in the wlcore driver is incorrect. As noted by Peter Zijlstra, casting arrays to a bitmap is incorrect for big-endian architectures. When looking at it I observed that: - operations on reg_ch_conf_pending is always under the wl_lock mutex, so set_bit is overkill - the only case where reg_ch_conf_pending is accessed a u32 at a time is unnecessary too. This patch cleans up everything in this area, and changes tmp_ch_bitmap to have the proper alignment.

wlcore: Add support for optional wakeirq Now with wlcore using PM runtime, we can also add support for Linux generic wakeirq handling for it if configured in the dts file. The wakeirq can be configured as the second interrupt in the dts file with interrupts-extended property where it is the padconf irq of the OOB GPIO pin used for wlcore interrupt. Note that eventually we should also allow configuring wlcore to use the SDIO dat1 IRQ for wake-up, and in that case the the wakeirq should be configured to be the padconf interrupt of the dat1 pin and not the padconf interrupt of the OOB GPIO pin.

wlcore: Add support for runtime PM We can update wlcore to use PM runtime by adding functions for wlcore_runtime_suspend() and wlcore_runtime_resume() and replacing calls to wl1271_ps_elp_wakeup() and wl1271_ps_elp_sleep() with calls to pm_runtime_get_sync() and pm_runtime_put(). Note that the new wlcore_runtime_suspend() and wlcore_runtime_resume() functions are based on simplified versions of wl1271_ps_elp_sleep() and wl1271_ps_elp_wakeup(). We don't want to use the old functions as we can now take advantage of the runtime PM usage count. And we don't need the old elp_work at all. And we can also remove WL1271_FLAG_ELP_REQUESTED that is no longer needed. Pretty much the only place where we are not just converting the existing functions is wl1271_op_suspend() where we add pm_runtime_put_noidle() to keep the calls paired. As the next step is to implement runtime PM autosuspend, let's not add wrapper functions for the generic runtime PM calls. We would be getting rid of any wrapper functions anyways. After autoidle we should be able to start using Linux generic wakeirqs for the padconf interrupt. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

wlcore: add missing nvs file name info for wilink8 The following commits: commit c815fdebef44 ("wlcore: spi: Populate config firmware data") commit d776fc86b82f ("wlcore: sdio: Populate config firmware data") Populated the nvs entry for wilink6 and wilink7 only while it is still needed for wilink8 as well. This broke user space backward compatibility when upgrading from older kernels, as the alternate mac address would not be read from the nvs that is present in the file system (lib/firmware/ti-connectivity/wl1271-nvs.bin) causing mac address change of the wlan interface. This patch fix this and update the structure field with the same default nvs file name that has been used before. In addition, some distros hold a default wl1271-nvs.bin in the file system with a bogus mac address (deadbeef...) that overrides the mac address that is stored inside the device.

wlcore: use separate HW queue for each AC in each vif Start using the new hw_queue mechanism in mac80211 and give each AC in each vif its own hw_queue number. This allows us to stop an AC in a vif independently from other vifs. Change the Tx watermark handling functions to count packets per AC in vif. From now on fast links should not be able to hurt the throughput of slow links on the same AC but on different vifs. Change internal queue mgmt functions to operate per vif, to support the new Tx watermark granularity. Make the global versions of the queue stop/start functions to use the global mac80211 API for queue mgmt. This helps in situations where the driver currently doesn't know all the vifs that reside in mac80211. Recovery is a good example for such a case.

wlcore/wl18xx: change priority calculations for links Update the 18xx FW status private part to include Tx related link priorities. Introduce new HW ops to determine link priority per chip family. For 18xx the changes are: - Suspended links are at most low priority and Tx for them is stopped beyond the suspend threshold. - Active links now get their thresholds directly from FW - There's a new "stop" threshold for active links, at which point a link stops receiving new packets. Update the min 18xx FW version required to make sure suspended links bitmap is advertised by the FW. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

wlcore: improved Tx scheduling algorithm Prioritize EDCA by choosing the AC before anything else. Use the fast/slow link bitmap in FW to improve the scheduling algorithm for the multi-link scenario. Set packet thresholds to determine if a given link is high or low priority according to its speed. A slow link will be given high priority if the amount of packets queued for it in the FW is lower than the slow-threshold. Similarly, a fast link will be given high priority if the number of its packets queued in FW is smaller than the high-threshold. The improved algorithm: 1. Choose optimal AC according to FW utilization 2. Traversing the VIFs in a round-robin fashion, try to choose a high priority link. Links are traversed in a round-robin fashion inside a VIF. 3. If no high priority links are found, choose the first non-empty (low priority) link found in the round robin.

wlcore: change way of checking the firmware version The firmwares version string contain 5 integers. We used to consider all the digits (except for the first one, which indicates the chip) as linearly increasing version numbers. This is not correct, because some of the integers indicate type of firmware (eg. single-role vs. multi-role) or the internal project it was created for. Besides, this varies a bit from chip to chip, so we need to make the firmware version checks more flexible (eg. allow the lower driver to ignore some of the integers). Additionally, we need to change the code so that we only check for a linearly increasing number on the fields where this actually makes sense. Signed-off-by: Luciano Coelho <coelho@ti.com>

wlcore: add new reg-domain configuration command In 18xx the calibration process of the PHY Cortex domain requires to perform an active calibration of the channel before it can be used for transmission. To fulfill world wide regulatory restrictions, fw should be always synchronized/updated with current CRDA configuration. Add a new "CMD_DFS_CHANNEL_CONFIG" command to update the fw with current reg-domain, this command passes a bit map of channels that are allowed to be used for transmission. The driver shall update the fw during initialization and after each change in the current reg-domain configuration. The driver will save the channel number of incoming beacons during the scan process, as they might be a result of the passive scan on "IEEE80211_CHAN_PASSIVE_SCAN" channel and will update the fw accordingly once the scan is finished, the purpose of this is to be ready in case of the authentication request on one of these disabled (uncalibrated) channels. The new command requires to wait for the fw completion event "DFS_CHANNELS_CONFIG_COMPLETE_EVENT". No scan commands (including the sched scan) can be executed concurrently with the "CMD_DFS_CHANNEL_CONFIG", wl->mutex ensures that.

wlcore: add stop reason bitmap for waking/starting queues Allow the driver to wake/stop the queues for multiple reasons. A queue is started when no stop-reasons exist. Convert all wake/stop queue calls to use the new API. Before, a stopped queue was almost synonymous a high-watermark on Tx. Remove a bit of code in wl12xx_tx_reset() that relied on it. Internal packets arriving from mac80211 are also discarded when a queue is stopped. A notable exception to this is the watermark reason, which is a "soft"-stop reason. We allow traffic to gradually come to a halt, but we don't mind spurious packets here and there. This is merely a flow regulation mechanism.

wlcore/wl12xx/wl18xx: handle spare blocks spacial cases per arch Add a HW op for getting spare blocks. 12xx cards require 2 spare blocks for GEM encrypted SKBs, regardless of VIFs or keys programmed into the FW. 18xx cards require 2 spare blocks when there are any connected TKIP or GEM VIFs. For now always return 2 spare blocks, as this works with all networks. The special case TKIP/GEM functionality is added at a later patch.

The call to wl1271_set_block_size() decides whether SDIO block size alignment can be used or not. In case we're using SPI, we can't use the block size alignment, so the function returns false. So we set the quirk when wl1271_set_block_size() returns true and let the wl12xx lower driver unset the bit for wl127x (since it doesn't support this quirk).
