This allows using all available memory.

The IOMMU is part of the decoder core but can be driven by the rockchip
iommu driver as a separate device.

The only issue with this is that the IOMMU hardware is reset when the
decoder is reset because of an error.
In this case, the IOMMU hardware looses all mappings but the mapped buffer
still retain their mapped address, cached in the IOMMU and decoder drivers.

To avoid that, when a decoding error occurs, the iommu_flush_iotlb_all
callback is used on the IOMMU to reconfigure the HW before continuing.

Add the rkvdec2 Video Decoder to the RK3588s devicetree.

Document the Rockchip RK3588 Video Decoder bindings.

Signed-off-by: Detlev Casanova <detlev.casanova@collabora.com>

This driver supports the second generation of the Rockchip Video
decoder, also known as vdpu34x.
It is currently only used on the RK3588(s) SoC.

There are 2 decoders on the RK3588 SoC that can work in pair to decode
8K video at 30 FPS but currently, only using one core at a time is
supported.

Scheduling requests between the two cores will be implemented later.

The core supports H264, HEVC, VP9 and AVS2 decoding but this driver
currently only supports H264.

The driver is based on rkvdec and they may share some code in the
future.
The decision to make a different driver is mainly because rkvdec2 has
more features and can work with multiple cores.

The registers are mapped in a struct in RAM using bitfields. It is IO
copied to the HW when all values are configured.
The decision to use such a struct instead of writing buffers one by one
is based on the following reasons:
 - Rockchip cores are known to misbehave when registers are not written
   in address order,
 - Those cores also need the software to write all registers, even if
   they are written their default values or are not related to the task
   (this core will not start decoding some H264 frames if some VP9
   registers are not written to 0)
 - In the future, to support multiple cores, the scheduler could be
   optimized by storing the precomputed registers values and copy them
   to the HW as soos as a core becomes available.

This makes the code more readable and may bring performance improvements
in future features.

Signed-off-by: Detlev Casanova <detlev.casanova@collabora.com>

The table will be shared with the rkvdec2 driver in following commits.

As HW formatted CABAC tables can be shared between drivers, it makes sense
to group them in an include folder.

Each driver can include the tables they need so that all tables are not
built in the kernel, but rather in each driver, if the driver is enabled.

Signed-off-by: Detlev Casanova <detlev.casanova@collabora.com>

This flag is needed for drivers that have a minimum height lower
than 32 pixels.

This is because when the flag is not set, the height is halved, which
would make it lower than 16 pixels if min height is 16.

Setting this flag will keep the height at its value and have a valid
SPS.

   - Bluetooth: fix possible infinite recursion of btusb_reset

 - Allow falling back from large pages to smaller pages (1MB or 4KB) if
   the allocation of 2GB pages in the decompressor can not be fulfilled

 - Add to the decompressor boot print support of "%%" format string,
   width and padding hadnling, length modifiers and decimal conversion
   specifiers

 - Add to the decompressor message severity levels similar to kernel
   ones. Support command-line options that control console output
   verbosity

 - Replaces boot_printk() calls with appropriate loglevel- specific
   helpers such as boot_emerg(), boot_warn(), and boot_debug().

 - Collect all boot messages into a ring buffer independent of the
   current log level. This is particularly useful for early crash
   analysis

 - If 'earlyprintk' command line parameter is not specified, store
   decompressor boot messages in a ring buffer to be printed later by
   the kernel, once the console driver is registered

 - Add 'bootdebug' command line parameter to enable printing of
   decompressor debug messages when needed. That parameters allows
   message suppressing and filtering

 - Dump boot messages on a decompressor crash, but only if 'bootdebug'
   command line parameter is enabled

 - When CONFIG_PRINTK_TIME is enabled, add timestamps to boot messages
   in the same format as regular printk()

 - Dump physical memory tracking information on boot: online ranges,
   reserved areas and vmem allocations

 - Dump virtual memory layout and randomization details

 - Improve decompression error reporting and dump the message ring
   buffer in case the boot failed and system halted

 - Add an exception handler which handles exceptions when FPU control
   register is attempted to be set to an invalid value. Remove '.fixup'
   section as result of this change

 - Use 'A', 'O', and 'R' inline assembly format flags, which allows
   recent Clang compilers to generate better FPU code

 - Rework uaccess code so it reads better and generates more efficient
   code

 - Cleanup futex inline assembly code

 - Disable KMSAN instrumention for futex inline assemblies, which
   contain dereferenced user pointers. Otherwise, shadows for the user
   pointers would be accessed

 - PFs which are not initially configured but in standby create only a
   single-function PCI domain. If they are configured later on, sibling

   breaking SR-IOV expectations.

Stephan Wurm reported that my recent patch broke VLAN support.

Apparently skb->mac_len is not correct for VLAN traffic as
shown by debug traces [1].

Use instead pskb_may_pull() to make sure the expected header
is present in skb->head.

Many thanks to Stephan for his help.

mptcp: blackhole only if 1st SYN retrans w/o MPC is accepted

Here are two small fixes for issues introduced in v6.12.

- Patch 1: reset the mpc_drop mark for other SYN retransmits, to only
  consider an MPTCP blackhole when the first SYN retransmitted without
  the MPTCP options is accepted, as initially intended.

- Patch 2: also mention in the doc that the blackhole_timeout sysctl
  knob is per-netns, like all the others.

All other sysctl entries mention it, and it is a per-namespace sysctl.

So mention it as well.

The Fixes commit mentioned this:

> An MPTCP firewall blackhole can be detected if the following SYN
> retransmission after a fallback to "plain" TCP is accepted.

But in fact, this blackhole was detected if any following SYN
retransmissions after a fallback to TCP was accepted.

That's because 'mptcp_subflow_early_fallback()' will set 'request_mptcp'
to 0, and 'mpc_drop' will never be reset to 0 after.

This is an issue, because some not so unusual situations might cause the
kernel to detect a false-positive blackhole, e.g. a client trying to
connect to a server while the network is not ready yet, causing a few
SYN retransmissions, before reaching the end server.

It was reported that the headphone output on Dell Venue 11 Pro 7130
becomes mono after PM resume.  The cause seems to be the BIOS setting
up the codec COEF 0x0d bit 0x40 wrongly by some reason, and restoring
the original value 0x2800 fixes the problem.

This patch adds the quirk entry to perform the COEF restore.

The field length description provides the length of each separated key
field in the concatenation, each field gets rounded up to 32-bits to
calculate the pipapo rule width from pipapo_init(). The set key length
provides the total size of the key aligned to 32-bits.

Register-based arithmetics still allows for combining mismatching set
key length and field length description, eg. set key length 10 and field
description [ 5, 4 ] leading to pipapo width of 12.

Fix missing rtnl lock in suspend path

Fix the suspend path by ensuring the rtnl lock is held where required.
Calls to open, close and WOL operations must be performed under the
rtnl lock to prevent conflicts with ongoing ndo operations.

While working on the ravb fix, it was discovered that the sh_eth driver
has the same issue. This patch series addresses both drivers.

I do not have access to hardware for either of these MACs, so it would
be great if maintainers or others with the relevant boards could test
these fixes.
