ath11k: Fix memory leak on error path

2020-10-08T10:45:55+00:00

In ath11k_mac_setup_iface_combinations(), if memory cannot be assigned
for the variable limits, then the memory assigned to combinations will
be leaked. Fix this.

wcn36xx: Advertise beacon filtering support in bmps

2020-10-01T19:34:04+00:00

In bmps mode, beacons are filtered, and firmware is in charge
of monitoring the beacons and report changes or loss.

mac80211 must be advertised about such change to prevent it's
internal timer based beacon monitor to report beacon loss.

Fix that by setting/clearing the IEEE80211_VIF_BEACON_FILTER
vif flag on bmps entry/exit.

ath11k: enable idle power save mode

2020-10-01T19:33:17+00:00

Host sends wmi command to allow hardware enter idle power
save mode in ath11k_mac_op_start function.

hw parameter idle_ps indicates whether idle power save is supported.

ath11k: start a timer to update HP for CE pipe 4

2020-10-01T19:33:15+00:00

For QCA6390, Start a timer to update CE pipe 4 ring HP when shadow
register is enabled. Its' to avoid that HP isn't updated to target
register.

ath11k: start a timer to update TCL HP

2020-10-01T19:33:09+00:00

The timer is to check if TCL HP isn't updated to target.
The timer will postpone itself if there are TX operations
during the interval, otherwise the timer handler updates
the HP again so the index value in HP register will be
forwarded to target register, and the timer stops afterwards.

ath11k: enable shadow register configuration and access

2020-10-01T19:33:04+00:00

To enable shadow register access, host needs to pass shadow
register configuration to firmware via qmi message. Host also
needs to update ring's HP or TP address to shadow register
address. The write operation to shadow register will be
forwarded to target register by hardware automatically, and
the write operation to shadow register is permitted even
when the target is in power save or sleep mode.

Update the shadow config whenever power up happens.

This feature is controlled by hw parameter supports_shadow_regs which is only
enabled for QCA6390.

ath11k: read and write registers below unwindowed address

2020-10-01T19:33:01+00:00

For QCA6390, host can read and write registers below unwindowed
address directly without programming the window register. For
registers below bar0 + 4k - 32, host can read and write regardless
of the power save state. Shadow registers are located below
bar0 + 4K - 32.

Before MHI power up, there is no need to wakeup MHI so ini_done is
added to indicate it.
