      iwlwifi: mvm: set different pm_timeout for action frames · b084a356
      由 Avri Altman 提交于 
      When building a Tx Command for management frames, we are lacking
a check for action frames, for which we should set a different
pm_timeout.  This cause the fw to stay awake for 100TU after each
such frame is transmitted, resulting an excessive power consumption.

      iwlwifi: mvm: Add FW paging mechanism for the UMAC on SDIO · e1120187
      由 Matti Gottlieb 提交于 
      Family 8000 products has 2 embedded processors, the first
known as LMAC (lower MAC) and implements the functionality from
previous products, the second one is known as UMAC (upper MAC)
and is used mainly for driver offloads as well as new features.
The UMAC is typically “less” real-time than the LMAC and is used
for higher level controls.
The UMAC's code/data size is estimated to be in the mega-byte arena,
taking into account the code it needs to replace in the driver and
the set of new features.

In order to allow the UMAC to execute code that is bigger than its code
memory, we allow the UMAC embedded processor to page out code pages on
DRAM.

When the device is slave on the bus(SDIO) the driver saves the UMAC's
image pages in blocks of 32K in the DRAM and sends the layout of the
pages to the FW. When the FW wants load / unload pages, it creates an
interrupt,	and the driver uploads / downloads the page to an address in
the a specific address on the device's memory.

The driver can support up to 1 MB of pages.

Add paging mechanism for the UMAC on SDIO in order to allow the program to
use a larger virtual space while using less physical memory on the device
itself.

      iwlwifi: pcie: New RBD allocation model · 26d535ae
      由 Sara Sharon 提交于 
      As a preperation for multiple RX queues change the RBD
allocation model.

The new model includes a background allocator. The allocator is
called by the interrupt handler when there are two released
buffers by the queue, and the allocator starts allocating eight
pages per request.
When the queue has released 8 pages it tries claiming the
request. If the pages are not ready - it keeps claiming.
This new model should make sure that RBDs are always available
across the multiple queues.

The RBDs are transferred between the allocator and the queue.
The queue moves the free RBDs upon freeing them to the allocator.
The allocator moves them back to the queue's possession when the
request is claimed.
The allocator has an initial pool to make sure there are always RBDs
available for the request completion.
Release of the buffers at exit is done per pools - the allocator
frees its own initial pool and the queue frees its own pool.

Existing code refactor -
-Queue's initial pool is the size of the queue only as the allocation
of the new buffers no longer uses this pool.
-Removal of replenish background work, and replenish calls in the
interrupt handler and restock().
-The replenish() and the rxq used_list are used only during
initialization.
-Moved page allocation to a new function for code reuse.

New code -
Allocator code - new structure and functions.
Interrupt handler uses the allocator functions for replenishing buffers.
Reuse of the restock() method.

      iwlwifi: mvm: add the ability to trigger only monitor dumps · 36fb9017
      由 Oren Givon 提交于 
      Change the FW debug trigger tlv to include a monitor only
option. Setting this option to true will cause fw dump triggers
to only collect monitor data and skip other dumps such as
SMEM, SRAM, CSR, PRPH, etc.
This option is used when accessing the different parts of the
firmware memory is not wanted and can cause unwanted behavior
like when debugging TX latency.
