f8a129c1e1 wifi: iwlwifi: lower message level for FW buffer destination
An invalid buffer destination is not a problem for the driver and it
does not make sense to report it with the KERN_ERR message level. As
such, change the message to use IWL_DEBUG_FW.

cb347bd29d wifi: iwlwifi: mvm: fix hibernation
Fast resume is a feature that was recently introduced to speed up the
resume time. It basically keeps the firmware alive while the system
is suspended and that avoids starting again the whole device.

This flow can't work for hibernation, since when the system boots,
before the frozen image is loaded, the kernel may touch the device. As a
result, we can't assume the device is in the exact same state as before
the hibernation.

Detect that we are resuming from hibernation through the PCI device and
forbid the fast resume flow. We also need to shut down the device
cleanly when that happens.

In addition, in case the device is power gated during S3, we won't be
able to keep the device alive. Detect this situation with BE200 at least
with the help of the CSR_FUNC_SCRATCH register and reset the device upon
resume if it was power gated during S3.

38c8d02501 wifi: iwlwifi: correctly lookup DMA address in SG table
The code to lookup the scatter gather table entry assumed that it was
possible to use sg_virt() in order to lookup the DMA address in a mapped
scatter gather table. However, this assumption is incorrect as the DMA
mapping code may merge multiple entries into one. In that case, the DMA
address space may have e.g. two consecutive pages which is correctly
represented by the scatter gather list entry, however the virtual
addresses for these two pages may differ and the relationship cannot be
resolved anymore.

Avoid this problem entirely by working with the offset into the mapped
area instead of using virtual addresses. With that we only use the DMA
length and DMA address from the scatter gather list entries. The
underlying DMA/IOMMU code is therefore free to merge two entries into
one even if the virtual addresses space for the area is not continuous.

a2ed933dfe wifi: iwlwifi: release TXQ lock during reclaim
Much of the work during reclaim can be done without holding the TXQ
lock and releasing the lock means that command submission can happen at
the same time.

Add a new reclaim_lock to prevent parallel cleanup. Release the lock
while working with an internal copy of the txq->read_ptr and only take
the lock again when updating the read pointer after the cleanup is done.

1a3364e963 wifi: iwlwifi: keep BHs disabled when TXing from reclaim
During reclaim, we may release the txq->lock spinlock in order to call
iwl_trans_tx to queue new frames. The iwl_trans_tx function expects to
be called with BHs disabled and iwl_pcie_reclaim is most of the times
called with BHs disabled already. However, reclaim can also happen after
flushing a STA and in that case BHs will not be disabled.

Solve this corner case by only releasing the spinlock but keeping BHs
disabled.

49101078be wifi: iwlwifi: pcie: integrate TX queue code
The TX queue code was mostly moved out to support an internal
transport that we were never going to publish, but we're no
longer using that. Since we're also going to be dissolving
the virtual transport layer entirely, integrate the TX queue
code into the PCIe layer.

This also has a small kernel of already removing the virtual
transport function layer, since iwl_trans_send_cmd() calls
iwl_trans_pcie_send_hcmd() directly now, even if that still
calls the transport send_cmd method for now, we'll clean it
up later.

Also, not everything is renamed yet.

b73c138a87 wifi: iwlwifi: pcie: allocate dummy net_device dynamically
struct net_device shouldn't be embedded into any structure, instead,
the owner should use the priv space to embed their state into net_device.

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_device from struct iwl_trans_pcie by converting it
into a pointer. Then use the leverage alloc_netdev() to allocate the
net_device object at iwl_trans_pcie_alloc.

The private data of net_device becomes a pointer for the struct
iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent
given the net_device object.

400f6ebbc1 wifi: iwlwifi: pcie: don't synchronize IRQs from IRQ
On older devices (before unified image!) we can end up calling
stop_device from an rfkill interrupt. However, in stop_device
we attempt to synchronize IRQs, which then of course deadlocks.

Avoid this by checking the context, if running from the IRQ
thread then don't synchronize. This wouldn't be correct on a
new device since RSS is supported, but older devices only have
a single interrupt/queue.

14c1b6f430 wifi: iwlwifi: remove async command callback
There's only one user of this code, which is STA unblock
during sleep for uAPSD on really old devices. Instead of
having this all through the API with calls up and down,
just implemented a special-case CMD_BLOCK_TXQS flag for
this, it's only needed in the old gen1 transport.

While at it, fix a complain that lockdep would have, as
we lock the cmd queue and then the TXQs in the reclaim
by using spin_lock_nested(). We no longer need to disable
BHs in iwl_trans_pcie_block_txq_ptrs() since it's called
with them disabled already.

1261fefa64 wifi: iwlwifi: refactor RX tracing
When there's not going to be any data in the data event, we
don't need to add it at all (unlike the TX version, it has
no data at all.)

Also combine the tracing into a separate inline so we only
call iwl_rx_trace_len() once, which also simplifies things,
and lets us have a single place to later add other checks.

interrupts are disabled, but interrupts may still be running

we won't reschedule the NAPI.
