Revert "dc: skip audio setup when audio stream is enabled"
This reverts commit 65fbfb02c2
[why]
We have minimal pipe split transition method to avoid pipe
allocation outage.However, this method will invoke audio setup
which cause audio output stuck once pipe reallocate.
[how]
skip audio setup for pipelines which audio stream has been enabled

[Why]
We rely on DMCUB to do this when disabling the link but it should
actually come before we disable the DP VID stream.
If we don't then the FIFO can end up with underflow that persists
the next time it's enabled.
[How]
Add a DCN314 specific blank sequence that will disable the DIG FIFO
first.

[Why]
The DIO FIFO will underflow if we turn off the OTG before we turn
off the FIFO.
Since this happens as part of the OTG workaround and we don't reset
the FIFO afterwards we see the error persist.
[How]
Add disable FIFO before the disable CRTC and enable FIFO after enabling
the CRTC.

[Why]
Avoids a race condition where DIO FIFO can underflow due to no incoming
data available.
[How]
Shift the FIFO enable below stream enable.
Make sure fullness level is written before the DIO reset takes place
and that we're not doing it twice.

I encountered some occasional crashes of poke_int3_handler() when
kprobes are set, while accessing desc->vec.
The text poke mechanism claims to have an RCU-like behavior, but it
does not appear that there is any quiescent state to ensure that
nobody holds reference to desc. As a result, the following race
appears to be possible, which can lead to memory corruption.
CPU0 CPU1
---- ----
text_poke_bp_batch()
-> smp_store_release(&bp_desc, &desc)
[ notice that desc is on
the stack ]
poke_int3_handler()
[ int3 might be kprobe's
so sync events are do not
help ]
-> try_get_desc(descp=&bp_desc)
desc = __READ_ONCE(bp_desc)
if (!desc) [false, success]
WRITE_ONCE(bp_desc, NULL);
atomic_dec_and_test(&desc.refs)
[ success, desc space on the stack
is being reused and might have
non-zero value. ]
arch_atomic_inc_not_zero(&desc->refs)
[ might succeed since desc points to
stack memory that was freed and might
be reused. ]
Fix this issue with small backportable patch. Instead of trying to
make RCU-like behavior for bp_desc, just eliminate the unnecessary
level of indirection of bp_desc, and hold the whole descriptor as a
global. Anyhow, there is only a single descriptor at any given
moment.

AF_XDP Tx descriptor cleaning in ice driver currently works in a "lazy"
way - descriptors are not cleaned immediately after send. We rather hold
on with cleaning until we see that free space in ring drops below
particular threshold. This was supposed to reduce the amount of
unnecessary work related to cleaning and instead of keeping the ring
empty, ring was rather saturated.
In AF_XDP realm cleaning Tx descriptors implies producing them to CQ.
This is a way of letting know user space that particular descriptor has
been sent, as John points out in [0].
We tried to implement serial descriptor cleaning which would be used in
conjunction with batched cleaning but it made code base more convoluted
and probably harder to maintain in future. Therefore we step away from
batched cleaning in a current form in favor of an approach where we set
RS bit on every last descriptor from a batch and clean always at the
beginning of ice_xmit_zc().
This means that we give up a bit of Tx performance, but this doesn't
hurt l2fwd scenario which is way more meaningful than txonly as this can
be treaten as AF_XDP based packet generator. l2fwd is not hurt due to
the fact that Tx side is much faster than Rx and Rx is the one that has
to catch Tx up.
FWIW Tx descriptors are still produced in a batched way.

Both i.MX6 and i.MX8 reference manuals list 0xBF8 as SNVS_HPVIDR1

Without this, trying to read the revision number results in 0 on
all revisions, causing the i.MX6 quirk to apply on all platforms,
which in turn causes the driver to synthesise power button release
events instead of passing the real one as they happen even on
platforms like i.MX8 where that's not wanted.

requests in the hsq of the host. The current code will check whether there
is a request doing recovery before entering the queue, but it will not check
whether there is a request when the lock is issued. The request is in recovery
mode. If there is a request in recovery, then a read and write request is
initiated at this time, and the conflict between the request and the recovery
request will cause the data to be trampled.

serdes in ADLink I-Pi SMARC board ethernet controller. Please refer to
commit b9663b7ca6 ("net: stmmac: Enable SERDES power up/down sequence")
for detial. When issue is reproduced, DMA engine clock is not ready
because serdes is not powered up.
To reproduce DMA engine reset timeout issue with hardware which has
serdes in GBE controller, install Ubuntu. In Ubuntu GUI, click
"Power Off/Log Out" -> "Suspend" menu, it disables network interface,
then goes to sleep mode. When it wakes up, it enables network
interface again. Stmmac driver is called in this way:
1. stmmac_release: Stop network interface. In this function, it
disables DMA engine and network interface;
2. stmmac_suspend: It is called in kernel suspend flow. But because
network interface has been disabled(netif_running(ndev) is
false), it does nothing and returns directly;
3. System goes into S3 or S0ix state. Some time later, system is
waken up by keyboard or mouse;
4. stmmac_resume: It does nothing because network interface has
been disabled;
5. stmmac_open: It is called to enable network interace again. DMA
engine is initialized in this API, but serdes is not power on so
there will be DMA engine reset timeout issue.
Similarly, serdes powerdown should be added in stmmac_release.
Network interface might be disabled by cmd "ifconfig eth0 down",
DMA engine, phy and mac have been disabled in ndo_stop callback,
serdes should be powered down as well. It doesn't make sense that
serdes is on while other components have been turned off.
If ethernet interface is in enabled state(netif_running(ndev) is true)
before suspend/resume, the issue couldn't be reproduced because serdes
could be powered up in stmmac_resume.
Because serdes_powerup is added in stmmac_open, it doesn't need to be
called in probe function.

During our testing of WFM200 module over SDIO on i.MX6Q-based platform,
we discovered a memory corruption on the system, tracing back to the wfx

cause, which is hw->max_rates set to 8 in wfx_init_common,
while the maximum defined by IEEE80211_TX_TABLE_SIZE is 4.
This causes array out-of-bounds writes during updates of the rate table,

Commit 10cb8e6175 ("mac80211: enable QoS support for nl80211 ctrl port")
changed ieee80211_tx_control_port() to aways call
__ieee80211_select_queue() without checking local->hw.queues.
__ieee80211_select_queue() returns a queue-id between 0 and 3, which means
that now ieee80211_tx_control_port() may end up setting the queue-mapping
for a skb to a value higher then local->hw.queues if local->hw.queues
is less then 4.
Specifically this is a problem for ralink rt2500-pci cards where
local->hw.queues is 2. There this causes rt2x00queue_get_tx_queue() to
return NULL and the following error to be logged: "ieee80211 phy0:
rt2x00mac_tx: Error - Attempt to send packet over invalid queue 2",
after which association with the AP fails.
Other callers of __ieee80211_select_queue() skip calling it when
local->hw.queues < IEEE80211_NUM_ACS, add the same check to
ieee80211_tx_control_port(). This fixes ralink rt2500-pci and
similar cards when less then 4 tx-queues no longer working.

Make sure local->queue_stop_reasons and vif.txqs_stopped stay in sync.
When a new vif is created the queues may end up in an inconsistent state
and be inoperable:
Communication not using iTXQ will work, allowing to e.g. complete the
association. But the 4-way handshake will time out. The sta will not
send out any skbs queued in iTXQs.
All normal attempts to start the queues will fail when reaching this
state.
local->queue_stop_reasons will have marked all queues as operational but
vif.txqs_stopped will still be set, creating an inconsistent internal
state.
In reality this seems to be race between the mac80211 function
ieee80211_do_open() setting SDATA_STATE_RUNNING and the wake_txqs_tasklet:
Depending on the driver and the timing the queues may end up to be
operational or not.

ieee80211_txq_purge() calls fq_tin_reset() and
ieee80211_purge_tx_queue(); Both are then calling
ieee80211_free_txskb(). Which can decide to TX the skb again.
There are at least two ways to get a deadlock:
1) When we have a TDLS teardown packet queued in either tin or frags
ieee80211_tdls_td_tx_handle() will call ieee80211_subif_start_xmit()
while we still hold fq->lock. ieee80211_txq_enqueue() will thus
deadlock.
2) A variant of the above happens if aggregation is up and running:
In that case ieee80211_iface_work() will deadlock with the original
task: The original tasks already holds fq->lock and tries to get
sta->lock after kicking off ieee80211_iface_work(). But the worker
can get sta->lock prior to the original task and will then spin for
fq->lock.
Avoid these deadlocks by not sending out any skbs when called via
ieee80211_free_txskb().

Quite often, the HW get stuck in error condition if a stream error
was detected. As documented, the HW should stop immediately and self
reset. There is likely a problem or a miss-understanding of the self
reset mechanism, as unless we make a long pause, the next command
will then report an error even if there is no error in it.
Disabling error detection fixes the issue, and let the decoder continue
after an error. This patch is safe for backport into older kernels.

Commit a1a2b7125e ("of/platform: Drop static setup of IRQ resource
from DT core") removed support for calling platform_get_resource(...,
IORESOURCE_IRQ, ...) on DT-based drivers, but the probe() function of
mtk-vcodec's encoder was still making use of it. This caused the encoder
driver to fail probe.
Since the platform_get_resource() call was only being used to check for
the presence of the interrupt (its returned resource wasn't even used)
and platform_get_irq() was already being used to get the IRQ, simply
drop the use of platform_get_resource(IORESOURCE_IRQ) and handle the
failure of platform_get_irq(), to get the driver probing again.

If allocating array_buf fails, or copying data from userspace into that
buffer fails, then just free memory and return the error. Don't attempt
to call video_put_user() since there is no point, and it would copy back
data on error even if INFO_FL_ALWAYS_COPY wasn't set.
So if writing the array back to userspace fails, then don't go to
out_array_args, instead just continue with the regular code that just
returns the error unless 'always_copy' is set.
Update the VIDIOC_G/S/TRY_EXT_CTRLS ioctls to set the ALWAYS_COPY flag
since they now need it. Before this worked due to this buggy code, but
now that that is fixed these ioctls need to set this flag explicitly.

The IOC_PR_CLEAR and IOC_PR_RELEASE ioctls are
non-functional on NVMe devices because the nvme_pr_clear()
and nvme_pr_release() functions set the IEKEY field incorrectly.
The IEKEY field should be set only when the key is zero (i.e,
not specified). The current code does it backwards.
Furthermore, the NVMe spec describes the persistent
reservation "clear" function as an option on the reservation
release command. The current implementation of nvme_pr_clear()
erroneously uses the reservation register command.
Fix these errors. Note that NVMe version 1.3 and later specify
that setting the IEKEY field will return an error of Invalid
Field in Command. The fix will set IEKEY when the key is zero,
which is appropriate as these ioctls consider a zero key to
be "unspecified", and the intention of the spec change is
to require a valid key.
Tested on a version 1.4 PCI NVMe device in an Azure VM.

Commit 1527f69204 ("ata: ahci: Add Green Sardine vendor ID as
board_ahci_mobile") added an explicit entry for AMD Green Sardine
AHCI controller using the board_ahci_mobile configuration (this
configuration has later been renamed to board_ahci_low_power).
The board_ahci_low_power configuration enables support for low power
modes.
This explicit entry takes precedence over the generic AHCI controller
entry, which does not enable support for low power modes.
Therefore, when commit 1527f69204 ("ata: ahci: Add Green Sardine
vendor ID as board_ahci_mobile") was backported to stable kernels,
it make some Pioneer optical drives, which was working perfectly fine
before the commit was backported, stop working.
The real problem is that the Pioneer optical drives do not handle low
power modes correctly. If these optical drives would have been tested
on another AHCI controller using the board_ahci_low_power configuration,
this issue would have been detected earlier.
Unfortunately, the board_ahci_low_power configuration is only used in
less than 15% of the total AHCI controller entries, so many devices
have never been tested with an AHCI controller with low power modes.

A recent change affecting the behaviour of phys_to_dma() to
actually require the device tree ranges to work unmasked a
bug in the Integrator DMA ranges.
The PL110 uses the CMA allocator to obtain coherent allocations
from a dedicated 1MB video memory, leading to the following
call chain:
drm_gem_cma_create()
dma_alloc_attrs()
dma_alloc_from_dev_coherent()
__dma_alloc_from_coherent()
dma_get_device_base()
phys_to_dma()
translate_phys_to_dma()
phys_to_dma() by way of translate_phys_to_dma() will nowadays not
provide 1:1 mappings unless the ranges are properly defined in
the device tree and reflected into the dev->dma_range_map.
There is a bug in the device trees because the DMA ranges are
incorrectly specified, and the patch uncovers this bug.
Solution:
- Fix the LB (logic bus) ranges to be 1-to-1 like they should
have always been.
- Provide a 1:1 dma-ranges attribute to the PL110.
- Mark the PL110 display controller as DMA coherent.
This makes the DMA ranges work right and makes the PL110
framebuffer work again.
