7265 features a new calibration which is called antenna coupling. The purpose of this calibration (which isn't really a calibration), is to measure the isolation between the antennas and that can give us useful information for the Coex modules. With this information, we can tune the LookUpTables (LUTs) that define the BT / WiFi contention policy. The LUTs currently contain dummy values - but they will be updated soon. While at it, change the current code to stop duplicate the host command while sending. This was needed back then, when the command was short enough to be allocated on the stack. Since then, the command grew a lot and is now allocated on the heap - hence we can use the NOCOPY option instead. Signed-off-by:

A scheduled scan is a more persistent setting and should take priority over temporary regular scans. Abort the regular when a sched_scan request arrives and then request the sched_scan. The kernel API allows sending a sched_scan without canceling a regular scan in progress, so this is our way to abstract the FW's limitations. Make the scan-cancel Rx handler async and flush after invocation to ensure new scans can't creep in before it. Signed-off-by:

cfg80211 assumes a scheduled scan is stopped synchronously. Wait for the FW before returning to caller. Don't do anything in the async handler in the stop-from-above flow. There's no need to call the mac80211 sched-scan completion as the cleanup will be automatic. Make sure the async handler is called before the next incoming scan changes the scan_status by flushing the async handlers after all invocations. Signed-off-by:

BGN SKU won't scan on 5.2GHz obviously, but the firmware still expects the driver to reserve space for the the probe request for the 5.2GHz band. Fix this by allocating space and leave it empty. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=69541Reviewed-by:

When indicating RF-kill toggle to the higher layer, that may in turn call back to the transport (for MVM at least) to turn off the device quickly. Instead of that, allow it to return whether or not the device should be turned off, this gets rid of the call indirection and will help make the API more consistent when we go back to non-threaded interrupts again for PCIe.

1. Enable LP XTAL to avoid HW bug where device may consume much power if FW is not loaded after device reset. LP XTAL is disabled by default after device HW reset. Configure device's "persistence" mode to avoid resetting XTAL again when SHRD_HW_RST occurs in S3. 2. Add methods to access SHR (shared block memory space) directly from PCI bus w/o need to power up MAC HW. Shared internal registers (e.g. SHR_APMG_GP1, SHR_APMG_XTAL_CFG)can be accessed directly from PCI bus through SHR arbiter even when MAC HW is powered down. This is possible due to indirect read/write via HEEP_CTRL_WRD_PCIEX_CTRL (0xEC) and HEEP_CTRL_WRD_PCIEX_DATA (0xF4) registers. Use iwl_write32()/iwl_read32() family to access these registers. The MAC HW need not be powered up so no "grab inc access" is required. For example, to read from SHR_APMG_GP1 register (0x1DC), first, write to the control register: HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register) HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 2 (read access) second, read from the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0]. To write the register, first, write to the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0] and then: HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register) HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 3 (write access) Signed-off-by:

When power update is initiated on BSS STA while P2P client exists, the power command will be sent only on BSS STA vif ignoring P2P client. Since the firmware has symmetric constraints on the power save enablement we can simplify the code a bit. The current firmware doesn't know how to enable power management on P2P client. Even BSS power management must be disabled when a P2P client is added. Future firmware will support power save on BSS and P2P client as long as they are on different channels. This was buggy since we didn't disable power management on P2P client interface if BSS added on the same channel. Signed-off-by:

This patch fixes the problem by updating MCS information field in HT capability when antenna setting changes so that correct information will be advertised in association and probe request.

We skip downloading other commands after FUNC_SHUTDOWN is queued during driver unload. Main thread should be woken up each time after freeing skipped command so that FUNC_SHUTDOWN gets served in case if there are other pending commands before FUNC_SHUTDOWN. Also, call mwifiex_complete_cmd() only for synchronous commands. Reported-by:

There is a race condition while queuing synchronous command and asynchronous command requested from different threads, because the wait_q_enabled flag is set based on a global variable cmd_wait_q_required. The issue is fixed by removing this global variable and using a unified function with an argument 'sync' passed into the function. Signed-off-by:
