Checkpatch issues "WARNING: else is not generally useful after a break
or return" for the following code:
while (1) {
do_join_r = rtw_do_join(padapter);
if (do_join_r == _SUCCESS) {
break;
} else {
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}
}
We simplify this code in multiple steps. First, we remove do_join_r
variable because it is only used right after it is assigned. Second,
we remove the unnecessary else statement right after break:
while (1) {
if (rtw_do_join(padapter) == _SUCCESS)
break;
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}
Next, we move the call to rtw_do_join into the while test because the
while will loop only until the call is successful:
while (rtw_do_join(padapter) != _SUCCESS) {
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}
Finally, looking at the code above, it is clear that the code will
break out of the loop if rtw_to_roam call is <= 0. Hence:
while (rtw_do_join(padapter) != _SUCCESS) {
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) <= 0) {
rtw_indicate_disconnect(padapter);
break;
}
}

The function iterates an index from 0 to NUM_PMKID_CACHE and returns
the first index for which the condition is true. If no such index is
found, the function returns -1. Current code has a complex control
flow that obfuscates this simple task. Replace it with a loop.
Also, given the shortened function body, replace the long variable
name psecuritypriv with a short variable name p.

The request to aqquire gem resources is failing for DSB in rare
scenario where it is busy and the register programming will be done
through mmio fallback path.
DSB has extra advantage of faster register programming which may
go away through mmio path. Adding wait for gem resource also may
not be right as anyways losing time.
To make the CI execution happy replaced drm_err() to drm_info()

Disable check for queue being enabled in ice_vc_dis_qs_msg, because
there could be a case when queues were created, but were not enabled.
We still need to delete those queues.
Normal workflow for VF looks like:
Enable path:
VIRTCHNL_OP_ADD_ETH_ADDR (opcode 10)
VIRTCHNL_OP_CONFIG_VSI_QUEUES (opcode 6)
VIRTCHNL_OP_ENABLE_QUEUES (opcode 8)
Disable path:
VIRTCHNL_OP_DISABLE_QUEUES (opcode 9)
VIRTCHNL_OP_DEL_ETH_ADDR (opcode 11)
The issue appears only in stress conditions when VF is enabled and
disabled very fast.
Eventually there will be a case, when queues are created by
VIRTCHNL_OP_CONFIG_VSI_QUEUES, but are not enabled by
VIRTCHNL_OP_ENABLE_QUEUES.
In turn, these queues are not deleted by VIRTCHNL_OP_DISABLE_QUEUES,
because there is a check whether queues are enabled in
ice_vc_dis_qs_msg.
When we bring up the VF again, we will see the "Failed to set LAN Tx queue
context" error during VIRTCHNL_OP_CONFIG_VSI_QUEUES step. This
happens because old 16 queues were not deleted and VF requests to create
16 more, but ice_sched_get_free_qparent in ice_ena_vsi_txq would fail to
find a parent node for first newly requested queue (because all nodes
are allocated to 16 old queues).
Testing Hints:
Just enable and disable VF fast enough, so it would be disabled before
reaching VIRTCHNL_OP_ENABLE_QUEUES.

When VF is freshly created, but not brought up, ring->txq_teid
value is by default set to 0.
But 0 is a valid TEID. On some platforms the Root Node of
Tx scheduler has a TEID = 0. This can cause issues as shown below.
The proper way is to set ring->txq_teid to ICE_INVAL_TEID (0xFFFFFFFF).
Testing Hints:
echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs
ip link set dev ens785f0v0 up
ip link set dev ens785f0v0 down
If we have freshly created VF and quickly turn it on and off, so there
would be no time to reach VIRTCHNL_OP_CONFIG_VSI_QUEUES stage, then
VIRTCHNL_OP_DISABLE_QUEUES stage will fail with error:
[ 639.531454] disable queue 89 failed 14
[ 639.532233] Failed to disable LAN Tx queues, error: ICE_ERR_AQ_ERROR
[ 639.533107] ice 0000:02:00.0: Failed to stop Tx ring 0 on VSI 5
The reason for the fail is that we are trying to send AQ command to
delete queue 89, which has never been created and receive an "invalid
argument" error from firmware.
As this queue has never been created, it's teid and ring->txq_teid
have default value 0.
ice_dis_vsi_txq has a check against non-existent queues:
node = ice_sched_find_node_by_teid(pi->root, q_teids[i]);
if (!node)
continue;
But on some platforms the Root Node of Tx scheduler has a teid = 0.
Hence, ice_sched_find_node_by_teid finds a node with teid = 0 (it is
pi->root), and we go further to submit an erroneous request to firmware.

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

BRS, to give a chance to the perf_events code to change its state before
a CPU goes to low power and after it comes back.
The callback is void when the PERF_NEEDS_LOPWR_CB flag is not set.
This flag must be set in arch specific perf_event.h header whenever needed.
When not set, there is no impact on the ACPI code.

Our YCbCr output is always supposed to be limited range BT.709.
That's what we send with native HDMI. The conn_state->colorspace
stuff is entirely independent of that and is not supposed to alter
the generated output in any way. If we want a way to do that then
we need a new proprty for it.
Make it so that the RGB->YCbCr conversion when performed by the
DPF will match the BT.709 we would transmit with native HDMI.

Previously we only checked the deep color cases. But I suppose

Currently we only look at the DFPs max TMDS clock limit when
considering whether the mode is valid, or whether we can do
deep color. The sink's max TMDS clock limit may be lower than
the DFPs, so we need to account for it as well.

The intended delay in ath11k_core_suspend is introduced in commit
d1b0c33850d2 ("ath11k: implement suspend for QCA6390 PCI devices"),
now with ath11k_mac_wait_tx_complete added in commit ba9177fcef21
("ath11k: Add basic WoW functionalities"), that delay is not
necessary now, so remove it.
This is found in code review.

The maximum number of SSIDs in a for active probe requests is currently
reported as 16 (WLAN_SCAN_PARAMS_MAX_SSID) when registering the driver.
The scan_req_params structure only has the capacity to hold 10 SSIDs.
This leads to a buffer overflow which can be triggered from
wpa_supplicant in userspace. When copying the SSIDs into the
scan_req_params structure in the ath11k_mac_op_hw_scan route, it can
overwrite the extraie pointer.
Firmware supports 16 ssid * 4 bssid, for each ssid 4 bssid combo probe
request will be sent, so totally 64 probe requests supported. So
set both max ssid and bssid to 16 and 4 respectively. Remove the
redundant macros of ssid and bssid.

Remove core PCI and ath11k PCI references(struct ath11k_pci)
from PCI common code. Since, PCI common code will be used
by hybrid bus devices, this code should be independent
from ATH11K PCI references and Linux core PCI references
like struct pci_dev.
Since this change introduces function callbacks for bus wakeup
and bus release operations, wakeup_mhi HW param is no longer
needed and hence it is removed completely. Alternatively, bus
wakeup/release ops for QCA9074 are initialized to NULL as
QCA9704 does not need bus wakeup/release for register accesses.

Instead of selecting MSI config based on magic numbers, make
the assignment based on HW revision. The logic is similar to
the selection of HW params. This improves readability of the
code and also simplifies new additions.

Unlike other ATH11K PCIe devices which are enumerated by APSS
processor (Application Processor SubSystem), WCN6750 gets
enumerated by the WPSS Q6 processor (Wireless Processor SubSystem);
In simple terms, though WCN6750 is PCIe device, it is not attached
to the APSS processor, APSS will not know of such a device being
present in the system and therefore WCN6750 will be registered as
a platform device to the kernel core like other supported AHB
devices.
WCN6750 needs both AHB and PCI APIs for it's operation, it uses
AHB APIs for device probe/boot and PCI APIs for device setup and
register accesses. Because of this nature, it is referred as a
hybrid bus device.
Refactor PCI code to support hybrid bus devices like WCN6750.

In order to add the support for WCN6750 in ATH11K , it is
required to move certain PCI definitions to the header file.
As a result, add ATH11K_PCI_* prefix to these definitions.
Also, change the scope of certain PCI APIs that are required
to enable WCN6750 from static to global.
