From: Maya Erez @ 2019-02-22 14:20 UTC (permalink / raw)
To: Kalle Valo; +Cc: Maya Erez, linux-wireless, wil6210
Due to a HW issue in PHY info collection rtap_include_phy_info is not
in use, hence can be removed.

From: Dedy Lansky <dlansky@codeaurora.org>
In AP mode with multiple clients, driver stops net queue
(netif_tx_stop_queue) upon first ring (serving specific client)
becoming full. This can have negative effect on transmission to
other clients which may still have room in their corresponding rings.
Implement new policy in which stop/wake net queue are not used. In
case there is no room in the ring for a transmitted packet, drop the
packet.
New policy can be helpful to debug performance issues, to guarantee
maximum utilization of net queues.
New policy is disabled by default and can be enabled by debugfs:
echo 1 > drop_if_ring_full

From: Ahmad Masri <amasri@codeaurora.org>
New FW added support for upto 20 clients in AP mode. Change the driver
to support this as well. FW reports it's max supported associations in
WMI_READY_EVENT. Some WMI commands/events use cidxtid field which is
limited to 16 cids. Use new cid/tid fields instead.
For Rx packets cid from rx descriptor is limited to 3 bits (0..7),
to find the real cid, compare transmitter address with the stored
stations mac address in the driver sta array.
EDMA FW still supports 8 stations. Extending the support to 20
stations will come later.

You shouldn't modify max_assoc_sta like this. If you have two wil6210
devices on the same host they will share that variable and there's a
race condition. Sure, I guess currently they will use the same firmware
so the values will be the same, but still this is a bug. I think you
should have wil->max_assoc_sta to make this device specific value.
I'll apply this anyway as it breaks all other patches if I remove this
patch. But please fix this in a follow up patch.

From: Dedy Lansky <dlansky@codeaurora.org>
Upon status ring handling, in case there are both unicast and
multicast (cid == max) status messages to handle, wrong sta statistics
might get updated.
Fix this by setting stats to NULL upon invalid cid
(e.g. == max_assoc_sta).

HALP ICR is set as long as the FW should stay awake.
To prevent its multiple handling the driver masks this IRQ bit.
However, if there is a different MISC ICR before the driver clears
this bit, there is a risk of race condition between HALP mask and
unmask. This race leads to HALP timeout, in case it is mistakenly
masked.
Add an atomic flag to indicate if HALP ICR should be handled.

ies1 or ies2 might be null when code inside
_wil_cfg80211_merge_extra_ies access them.
Add explicit check for null and make sure ies1/ies2 are not
accessed in such a case.
spos might be null and be accessed inside
_wil_cfg80211_merge_extra_ies.
Add explicit check for null in the while condition statement
and make sure spos is not accessed in such a case.

Accessing some of the memory of the device while the device is
resetting or suspending may cause unexpected error as the HW is still
not in a stable state. Prevent this access to guarantee successful
read/write memory operations.

In case there are connected stations, FW needs to disconnect
them before handling PCP stop. This flow can take several
seconds.
Increasing PCP stop timeout to 5 seconds to allow that.

In Sparrow, FW might sleep long time due to T_Power_On calculation
in slow clock, so T_Power_On was set to zero to shorten the L1SS
wake-up time.
In Talyn-MB the L1SS wake-up procedure is handled by the PMU (HW),
hence T_Power_On calculation is accurate and should not be forced
to zero.

Update max MCS to 15, which is supported by Talyn-MB.
This will allow collecting statistics on number of RX packets
in higher MCS.

In addition to existing MAC address field in OTP, new field added for

wil6210 gives precedence to the new OEM MAC address and will use it if
its valid.

Update the rx packet checksum of received packet according to edma
HW spec:
No need to calculate checksum in the following cases:
L4_status=0 and L3_status=0 - No L3 and no L4 known protocols found
L4_status=0 and L3_status=1 - L3 was found, and checksum check passed.
No known L4 protocol was found.
L4_status=1 - L4 was found, and checksum check passed.
Recalculate checksum in the following cases:
L4_status=3 and L3_status=1 - It means that L3 protocol was found,
and checksum passed, but L4 checksum failed.
L4_status=3 and L3_status=2 - Both L3 and L4 checksum check failed.

The functions that send management TX frame have 3 possible
results: success and other side acknowledged receive (ACK=1),
success and other side did not acknowledge receive(ACK=0) and
failure to send the frame. The current implementation
incorrectly reports the ACK=0 case as failure.

Due to access control RGF_CAF_ICR cannot be accessed by host.
Such an access will cause device AHB logger to halt and it will not
capture future AHB fault if there is any.

The driver needs to expose RGF_USER_USAGE_2 register that contains
the offset of the ucode logging table.

Since DR bit and buffer id are written in different dwords of
the status message, the DR bit can already be set to 1 while the
buffer id is not updated yet.
Resetting the buffer id in the status message will allow the driver
to identify such cases and re-read the status message until the buffer
id is written by HW.
In case DR bit is set but buffer id is zero, need to read the status
message again, until a valid id is identified.
In addition to that, move the completed buffer id to the tail of the
free list to prevent its immediate reuse in the upcoming refill.

Add an error print-out in case FW and board files load fails,
as such an error is not printed on all failures and user may
not understand why the interface up operations didn't succeed.

21 patches is just too much to review. I'll review (and apply) these in
smaller sets. Ideally these should have been split into 3 smaller sets
and only one set at a time in review queue, that they would be applied a
lot faster.
