====================
mlxsw: Unified bridge conversion - part 1/6
This set starts converting mlxsw to the unified bridge model and mainly
adds new device registers and extends existing ones that will be used in
follow-up patchsets.
High-level summary
==================
The unified bridge model is a new way of managing low-level device
objects such as filtering identifiers (FIDs). The conversion moves a lot
of logic out of the device's firmware towards the driver, but its main
selling point is that it allows to overcome various scalability issues
related to the amount of entries that need to be programmed to the
device.
The only (intended) user visible changes of the conversion are
improvement in resource utilization and ability to support more router
interfaces (RIFs) in Spectrum-{2,3}.
Details
=======
Commit 50853808ff ("Merge branch
'mlxsw-Prepare-for-VLAN-aware-bridge-w-VxLAN'") converted mlxsw to
emulate 802.1Q FIDs (represent VLANs in a VLAN-aware bridge) using
802.1D FIDs (represent VLAN-unaware bridges). This was necessary because
at that time VNI could not be assigned to 802.1Q FIDs, which effectively
meant that mlxsw could not support VXLAN with VLAN-aware bridges.
The downside of this approach is that multiple {Port,VID}->FID entries
are required in order to classify incoming traffic to a FID, as opposed
to a single VID->FID entry that can be used with actual 802.1Q FIDs.
For example, if 10 ports are members in the same VLAN-aware bridge and
the same 100 VLANs are configured on each port, then only 100 VID->FID
entries are required with 802.1Q FIDs, whereas 1000 {Port,VID}->FID
entries are required with emulated 802.1Q FIDs.
The above limitation is the result of various assumptions that were made
in the design of the API that was exposed to software. In the unified
bridge model the API is much more "raw" and therefore avoids these
assumptions, allowing software to configure the device in a more
efficient manner.

Router interfaces (RIFs) constructed on top of VLAN-aware bridges are of
"VLAN" type, whereas RIFs constructed on top of VLAN-unaware bridges of
"FID" type.
In other words, the RIF type is derived from the underlying FID type.
VLAN RIFs are used on top of 802.1Q FIDs, whereas FID RIFs are used on
top of 802.1D FIDs.
Currently 802.1Q FIDs are emulated using 802.1D FIDs, and therefore VLAN
RIFs are emulated using FID RIFs.
As part of converting the driver to use unified bridge, 802.1Q FIDs and
VLAN RIFs will be used.
Add the relevant fields to RITR register, add pack() function for VLAN
RIF and rename one field to fit the internal name.

As preparation for unified bridge model, add support for VNI->FID mapping
via SVFA register.
When performing VXLAN encapsulation, the VXLAN header needs to contain a
VNI. This VNI is derived from the FID classification performed on
ingress, through which the ingress RIF is also determined.
Similarly, when performing VXLAN decapsulation, the FID of the packet
needs to be determined. This FID is derived from VNI classification
performed during decapsulation.
In the old model, both entries (i.e., FID->VNI and VNI->FID) were
configured via SFMR.vni.
In the new model, where ingress is separated from egress, ingress
configuration (VNI->FID) is performed via SVFA, while SFMR only
configures egress (FID->VNI).
Add 'vni' field to SVFA, add new mapping table - VNI to FID, add new
pack() function for VNI mapping and edit the comment in SFMR.

As preparation for unified bridge model, add REIV register for future use.
In the past, firmware would take care of the above mentioned mapping,
but in the new model this should be done by software using REIV register.
REIV register supports a simultaneous update of 256 ports using

0-255, when 'port_page'=1 the records represent ports 256-511 and so

As preparation for unified bridge model, remove 'mid' field and add

The MID index (index to PGT table which maps MID to local port list and
SMPE index) is a result of 'mid_base' + 'fid_offset'. Using the legacy
bridge model, firmware configures 'mid_base'. However, using the new model,
software is responsible to configure it via SFGC register.
The 'mid_base' is configured per {packet type, bridge type}, for

The PGT (Port Group) table maps multicast ID (MID) to

The configuration of MDB entries (using SFD) is unchanged, but flooding
configuration is completely different.
SFGC register maps {packet type, bridge type} -> {MID base, table type},
then with FID and FID-offset which are configured via SFMR, the MID index
is obtained.

The recent report for a crash on Haswell machines implied that the
x86-specific (rather hackish) implementation for write-cache memory
buffer allocation in ALSA core is buggy with the recent kernel in some
corner cases. This patch drops the x86-specific implementation and
uses the standard dma_alloc_wc() & co generically for avoiding the bug
and also for simplification.

While watching Michael's new talk on Clang-built-Linux, I noticed the
arch table in our docs that he refers to is outdated.
Add hexagon and User Mode. Bump MIPS and RISCV to LLVM=1. PowerPC is
almost LLVM=1 capable; ppc64le works, but ppc64 (big endian) and ppc32
still need more work.

random.c ratelimits how much it warns about uninitialized urandom reads
using __ratelimit(). When the RNG is finally initialized, it prints the
number of missed messages due to ratelimiting.
It has been this way since that functionality was introduced back in
2018. Recently, cc1e127bfa ("random: remove ratelimiting for in-kernel
unseeded randomness") put a bit more stress on the urandom ratelimiting,
which teased out a bug in the implementation.
Specifically, when under pressure, __ratelimit() will print its own
message and reset the count back to 0, making the final message at the
end less useful. Secondly, it does so as a pr_warn(), which apparently
is undesirable for people's CI.
Fortunately, __ratelimit() has the RATELIMIT_MSG_ON_RELEASE flag exactly
for this purpose, so we set the flag.

It used to be that mix_interrupt_randomness() would credit 1 bit each
time it ran, and so add_interrupt_randomness() would schedule mix() to
run every 64 interrupts, a fairly arbitrary number, but nonetheless
considered to be a decent enough conservative estimate.
Since e3e33fc2ea ("random: do not use input pool from hard IRQs"),
mix() is now able to credit multiple bits, depending on the number of
calls to add(). This was done for reasons separate from this commit, but
it has the nice side effect of enabling this patch to schedule mix()
less often.
Currently the rules are:
a) Credit 1 bit for every 64 calls to add().
b) Schedule mix() once a second that add() is called.
c) Schedule mix() once every 64 calls to add().
Rules (a) and (c) no longer need to be coupled. It's still important to
have _some_ value in (c), so that we don't "over-saturate" the fast
pool, but the once per second we get from rule (b) is a plenty enough
baseline. So, by increasing the 64 in rule (c) to something larger, we
avoid calling queue_work_on() as frequently during irq storms.
This commit changes that 64 in rule (c) to be 1024, which means we
schedule mix() 16 times less often. And it does *not* need to change the
64 in rule (a).

If the vrefint calibration is zero, the vrefint channel output value
cannot be computed. Currently, in such case, the raw conversion value
is returned, which is not relevant.
Do not expose the vrefint channel when the output value cannot be

IIO trigger interface function iio_trigger_get() should be called after
iio_trigger_register() (or its devm analogue) strictly, because of
iio_trigger_get() acquires module refcnt based on the trigger->owner
pointer, which is initialized inside iio_trigger_register() to
THIS_MODULE.
If this call order is wrong, the next iio_trigger_put() (from sysfs
callback or "delete module" path) will dereference "default" module
refcnt, which is incorrect behaviour.
