If the topology filename is modified at a higher level, be it with a
DMI quirk or a kernel module parameter, we don't want to use the
default 'nocodec' topology name extracted from descriptors.

The existing 'tplg_path' module parameter can be used to load
alternate firmware files, be it for development or to handle
OEM-specific or board-specific releases. However the topology filename
is either hard-coded in machine descriptors or modified by specific
DMI-quirks.
For additional flexibility, this patch adds the 'tplg_filename' module
parameter to override topology names.
To avoid any confusion between DMI- and parameter-override, a variable
rename is added.

The existing 'fw_path' module parameter can be used to load alternate

and defined by platform-specific descriptors.
For additional flexibility during development or enable quirks, this

This patch adds a default IPC type for each platform, along with file
paths to be used for each IPC type. To make reviews simpler, we only
modify platform descriptors in this table, the information will be
used in the next patch.
The Intel IPCv4 is only supported on Intel platforms after APL, and
not by default. In follow-up patches, support for SKL and KBL will be
added, and in those two cases the IPCv4 will be the default (and only
supported mode).

This patch allows users to pick queue_mapping, range
from A to B. Then we can load balance packets from A
to B tx queue. The range is an unsigned 16bit value
in decimal format.
$ tc filter ... action skbedit queue_mapping skbhash A B
"skbedit queue_mapping QUEUE_MAPPING" (from "man 8 tc-skbedit")

For example:
If P1 sends out packets to different Pods on other host, and
we want distribute flows from qn - qm. Then we can use skb->hash
as hash.

This patch fixes issue:
* If we install tc filters with act_skbedit in clsact hook.
It doesn't work, because netdev_core_pick_tx() overwrites
queue_mapping.
$ tc filter ... action skbedit queue_mapping 1
And this patch is useful:
* We can use FQ + EDT to implement efficient policies. Tx queues
are picked by xps, ndo_select_queue of netdev driver, or skb hash
in netdev_core_pick_tx(). In fact, the netdev driver, and skb
hash are _not_ under control. xps uses the CPUs map to select Tx
queues, but we can't figure out which task_struct of pod/containter
running on this cpu in most case. We can use clsact filters to classify
one pod/container traffic to one Tx queue. Why ?
In containter networking environment, there are two kinds of pod/
containter/net-namespace. One kind (e.g. P1, P2), the high throughput
is key in these applications. But avoid running out of network resource,
the outbound traffic of these pods is limited, using or sharing one
dedicated Tx queues assigned HTB/TBF/FQ Qdisc. Other kind of pods
(e.g. Pn), the low latency of data access is key. And the traffic is not
limited. Pods use or share other dedicated Tx queues assigned FIFO Qdisc.
This choice provides two benefits. First, contention on the HTB/FQ Qdisc
lock is significantly reduced since fewer CPUs contend for the same queue.
More importantly, Qdisc contention can be eliminated completely if each
CPU has its own FIFO Qdisc for the second kind of pods.
There must be a mechanism in place to support classifying traffic based on
pods/container to different Tx queues. Note that clsact is outside of Qdisc
while Qdisc can run a classifier to select a sub-queue under the lock.
In general recording the decision in the skb seems a little heavy handed.
This patch introduces a per-CPU variable, suggested by Eric.
The xmit.skip_txqueue flag is firstly cleared in __dev_queue_xmit().
- Tx Qdisc may install that skbedit actions, then xmit.skip_txqueue flag
is set in qdisc->enqueue() though tx queue has been selected in
netdev_tx_queue_mapping() or netdev_core_pick_tx(). That flag is cleared
firstly in __dev_queue_xmit(), is useful:
- Avoid picking Tx queue with netdev_tx_queue_mapping() in next netdev
in such case: eth0 macvlan - eth0.3 vlan - eth0 ixgbe-phy:
For example, eth0, macvlan in pod, which root Qdisc install skbedit
queue_mapping, send packets to eth0.3, vlan in host. In __dev_queue_xmit() of
eth0.3, clear the flag, does not select tx queue according to skb->queue_mapping
because there is no filters in clsact or tx Qdisc of this netdev.
Same action taked in eth0, ixgbe in Host.
- Avoid picking Tx queue for next packet. If we set xmit.skip_txqueue
in tx Qdisc (qdisc->enqueue()), the proper way to clear it is clearing it
in __dev_queue_xmit when processing next packets.
For performance reasons, use the static key. If user does not config the NET_EGRESS,
the patch will not be compiled.

The dmc520 driver requires that at least one interrupt line, out of the
ten possible, is configured. The driver prints an error and returns
-EINVAL from its .probe function if there are no interrupt lines
configured.
Don't print a KERN_ERR level message for each interrupt line that's
unconfigured as that can confuse users into thinking that there is an
error condition.
Before this change, the following KERN_ERR level messages would be
reported if only dram_ecc_errc and dram_ecc_errd were configured in the
device tree:

bridge link set dev $br_port mcast_flood on
this command should affect not only L2 multicast, but also IPv4 and IPv6
multicast.
In the Ocelot switch, unknown multicast gets flooded according to
different PGIDs according to its type, and PGID_MC only handles L2
multicast. Therefore, by leaving PGID_MCIPV4 and PGID_MCIPV6 at their
default value of 0, unknown IP multicast traffic is never flooded.

In case the checksum calculation is offloaded to the DSA master network
interface, it will include the switch trailing tag. As soon as the switch strips
that tag on egress, the calculated checksum is wrong.
Therefore, add the checksum calculation to the tagger (if required) before
adding the switch tag. This way, the hellcreek code works with all DSA master
interfaces regardless of their declared feature set.

Brad reported that on Apple hardware with Light Ridge or Falcon Ridge
controller, plugging in a chain of Thunderbolt displays (Light Ridge
based controllers) causes all kinds of tearing and flickering. The
reason for this is that on Thunderbolt 1 hardware there is no lane
bonding so we have two independent 10 Gb/s lanes, and currently Linux
tunnels both displays through the lane 1. This makes the displays to
share the 10 Gb/s bandwidth which may not be enough for higher
resolutions.
For this reason make the second tunnel go through the lane 0 instead.
This seems to match what the macOS connection manager is also doing.

With some VRR panels, user can turn VRR ON/OFF on the fly from the panel settings.
When VRR is turned OFF ,sends a long HPD to the driver clearing the Ignore MSA bit
in the DPCD. Currently the driver parses that onevery HPD but fails to reset
the corresponding VRR Capable Connector property.
Hence the userspace still sees this as VRR Capable panel which is incorrect.
Fix this by explicitly resetting the connector property.

The USB audio device 0db0:a073 based on the Realtek ALC4080 chipset
exposes all playback volume controls as "PCM". This makes
distinguishing the individual functions hard.
The mapping already adopted for device 0db0:419c based on the same
chipset fixes the issue, apply it for this device too.

pci_get_class() will already unref the pci device passed as argument.
So if it's unconditionally unref'ed, even if the loop is not stopped,
there will be one too many unref for each device not matched.

This is a pre-req to add separate logging for each subtest in
test_progs.
Move all the mutable test data to the test_result struct.
Move per-test init/de-init into the run_one_test function.
Consolidate data aggregation and final log output in
calculate_and_print_summary function.
As a side effect, this patch fixes double counting of errors
for subtests and possible duplicate output of subtest log
on failures.
Also, add prog_tests_framework.c test to verify some of the
counting logic.
As part of verification, confirmed that number of reported
tests is the same before and after the change for both parallel
and sequential test execution.

Commit 413dda8f2c6f ("platform/chrome: cros_ec_chardev: Use
cros_ec_cmd_xfer_status helper") inadvertendly changed the userspace ABI.
Previously, cros_ec ioctls would only report errors if the EC communication
failed, and otherwise return success and the result of the EC
communication. An EC command execution failure was reported in the EC
response field. The above mentioned commit changed this behavior, and the
ioctl itself would fail. This breaks userspace commands trying to analyze
the EC command execution error since the actual EC command response is no
longer reported to userspace.
Fix the problem by re-introducing the cros_ec_cmd_xfer() helper, and use it
to handle ioctl messages.

The maximum SCSI device queue depth of 1024 is not sufficient for RAID
volumes configured behind Broadcom RAID controllers. For a 16-drive RAID
volume with a device queue depth limit of 1024, only 64 I/Os (1024/16) can
be issued per drive. That is not sufficient to saturate the device.

"This does not apply if only one branch of a conditional statement is a
single statement; in the latter case use braces in both branches"

supported by the HBA.
Move setting ELS_ID logic into __lpfc_sli_prep_els_req_rsp_s4(), and remove

Introduce PLOGI ELS_ID and as a result update wqe_els_id_MASK because PLOGI
ELS_ID = 0x4 occupies up to 3 bits.
While in __lpfc_sli_prep_els_req_rsp_s4() routine, remove SLI3-isms.

Do not rely on vendor version field of the CSPs to determine if we are in a
FA-PWWN environment. Instead, use the following procedure:
First, during HBA initialization, driver does a READ_CONFIG to determine if
FA-PWWN is configured on the HBA. A LPFC_FAWWPN_CONFIG hba_flag is set
accordingly.
Next, when the link comes up before the driver gets a link up event, the
firmware logs into the fabric with FA-PWWN. If the fabric port does not
support FA-PWWN, the driver will get a Misconfigured FA-WWN async event
before the link up. A LPFC_FAWWPN_FABRIC hba_flag will be set accordingly.
Finally, if the fabric supports FA-PWWN, the firmware will replace its CSPs
WWN with the Fabric Assigned ones. Then after link up, the driver will
retrieve the Fabric Assigned WWN when it does a READ_SPARAM mbox command.

The intention of this patch is to refactor mailbox memory allocation and
cleanup steps in one routine respectively to prevent memory leaks or memory
errors related to mailbox commands. There are trivial localized fixes as
well.
Provide lpfc_mbox_rsrc_prep() - this routine allocates the dmabuf and the
mbuf associated with it. It also catches allocation errors and returns
status.
Provide lpfc_mbox_rsrc_cleanup() - this routine verifies a dmabuf exists
and if so releases the associated mbuf and the dmabuf memory. It then sets
the ctx_buf to NULL and releases the mailbox memory to the mailbox pool.

The lpfc_iocbq data structure has void * pointers that are overloaded to be
as many as 8 different data types and the driver translates the void * by
casting. This patch removes the void * pointers by declaring the specific
types needed by the driver. It also expands the context_un to include more
seldom used pointer types to save structure bytes. It also groups the u8
types together to pack the 8 bytes needed. This work allows the lpfc_iocbq
data structure to be more strongly typed and keeps it from being allocated
from the 512 byte slab.

During an NVMe target reboot, the target may initialize itself as FCP only
during the first RSCN and shortly after trigger a second RSCN claiming NVMe
support. The timing of these RSCNs occur before FCP-PRLI for the first
RSCN completes leading discovery issues over NVMe.
Change RSCN and NVME-PRLI send logic based on a new FC_RSCN_MEMENTO flag
that signals when lpfc_end_rscn() is completed and serves as a memento that
discovery was started from RSCN.
