e04ffd120f mlx4: remove custom dev_addr clearing
mlx4_en_u64_to_mac() takes the dev->dev_addr pointer and writes
to it byte by byte. It also clears the two bytes _after_ ETH_ALEN
which seems unnecessary. dev->addr_len is set to ETH_ALEN just
before the call.

ASoC: SOF: topology: allow for dynamic pipelines override for debug
For debug and community support, it's useful to expose a kernel
parameter to prevent the use of dynamic pipelines exposed in a
topology file, or conversely to force an existing topology to use
dynamic pipelines.

Add an override bit and an enable bit which is valid only when the
override is set.

For products, the intent is that the topology file defines the
behavior, these two bits are only intended for diagnosis and
performance checks.

ASoC: SOF: Intel: hda-dai: improve SSP DAI handling for dynamic pipelines
In order to keep the widget use_count balanced, make sure the DAI
widgets are allocated once in hw_params and released in hw_free. A
'setup' status flag is used to deal with cases where the .hw_params
callback is invoked multiple times, and likewise with cases where
hw_free is invoked without hw_params being called first (which can
happen if the FE hw_params fails).

In addition, this patch frees the widgets in the suspend transition,
and reallocates them in the .prepare callback. The 'setup' flag helps
in this case differentiate between resume (setup needed) and
xruns (setup not needed).

This balanced operation was not needed previously but will be required
when SOF dynamic pipelines are enabled.

21c51692fc
ASoC: SOF: dai: include new flags for DAI_CONFIG
Mirror changes done in SOF tree. The changes do not rely on
BIT/GENMASK on purpose to keep the structure and flags common with the
firmware tree.

The DAI_CONFIG IPC is currently used in multiple ways. It is sent to
the DSP firmware when enabling static or dynamic pipelines, in
hw_params or prepare callbacks for Intel SSP, HDaudio and ALH, on
trigger_stop and hw_free.

This IPC has been abused a bit in the past, i.e. the values used for
some of the DAI-specific fields are used to either allocate or free
resources. Two typical examples are Intel HDaudio and SoundWire/ALH
DAIs, where using a zero DMA channel number or stream tag signals to
the firmware the DMA channels or tags allocated earlier can be freed.

Rather than add a new IPC for 'hw_params' and 'hw_free', this patch
suggests supporting a 2-bit value conveying the 'stage' information in
an existing IPC structure. Only 3 possible values are used.

The mapping between HW_PARAMS and HW_FREE flags and ALSA definitions
is not strictly 1:1, e.g. in some cases the HW_PARAM flag might be set
during the .prepare callback, while the HW_FREE might be sent during the
ALSA .trigger for stop/suspend.

The semantics of the flags is to reserve and start/stop all needed
resources, typically hardware related such as DMAs or clocks, when the
HW_PARAMS is set, while the HW_FREE flag allows the firmware to
release the resources allocated. The data transfers are still
controlled within the firmware through the propagation of the trigger
command.

The driver can then pass information that the DAI_CONFIG was invoked
in e.g. a pipeline/DAI setup, hw_params or hw_free stage without
having to use a special DAI-specific encoding. Unfortunately we can't
remove old encodings due to backwards-compatibility requirements but
for new cases, such as the SSP in follow-up patches, we can make the
IPC less cryptic.

This change is tagged as ABI 3.19 and is completely backwards compatible.

We force the FCR contents on many places in the code instead of writing
what was actually set in mxser_change_speed() (by ->activate() or

So introduce mxser_port::FCR to hold the proper contents and bitwise-OR
the value to what needs to be set on all those locations. That is,
clearing RX and/or TX FIFOs. Those flags are self-clearing, so no need
to set them to mxser_port::FCR.

215fa41c2d mxser: don't read from UART_FCR

performed in mxser_flush_buffer() to clear FIFOs.

Actually FCR handling throughout the driver is completely broken. On
many places, it respects neither mu860 settings, nor FIFO (16450 vs
16550) setting. This patch doesn't help to fix this, it actually does
the same. We will introduce a mxser_port::FCR in the next patch to fix

7615c2a514 KVM: arm64: Report corrupted refcount at EL2
Some of the refcount manipulation helpers used at EL2 are instrumented
to catch a corrupted state, but not all of them are treated equally. Let's
make things more consistent by instrumenting hyp_page_ref_dec_and_test()
as well.

1d58a17ef5 KVM: arm64: Fix host stage-2 PGD refcount
The KVM page-table library refcounts the pages of concatenated stage-2
PGDs individually. However, when running KVM in protected mode, the
host's stage-2 PGD is currently managed by EL2 as a single high-order
compound page, which can cause the refcount of the tail pages to reach 0
when they shouldn't, hence corrupting the page-table.

Fix this by introducing a new hyp_split_page() helper in the EL2 page
allocator (matching the kernel's split_page() function), and make use of
it from host_s2_zalloc_pages_exact().

059747c245 ipmi: Add support for IPMB direct messages
An application has come up that has a device sitting right on the IPMB
that would like to communicate with the BMC on the IPMB using normal
IPMI commands.

Sending these commands and handling the responses is easy enough, no
modifications are needed to the IPMI infrastructure.  But if this is an
application that also needs to receive IPMB commands and respond, some
way is needed to handle these incoming commands and send the responses.

Currently, the IPMI message handler only sends commands to the interface
and only receives responses from interface.  This change extends the
interface to receive commands/responses and send commands/responses.
These are formatted differently in support of receiving/sending IPMB
messages directly.
