There are some Dell SKUs that need to set the parameters of the
crossover filter (biquad). Each amplifier connects to one tweeter
speaker and one woofer speaker. We should control HPF/LPF to output the
proper frequency for the different speakers. If the codec driver got
the BQ parameters from the device property, it will apply these
parameters to the hardware.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
with SOF topology2 for IPC4, widgets might have mutliple queues they can be
connected.
The queues to use between components are descibed in the topology file.
This series adds widget queue support (specify which pin to connect) for
ipc4-topology with topology2.
Note: currently queue 0 of a widget is used as hardwired default.
|
|
Add support for parsing sink/source pin binding array
per widget from topology. The pin binding arrays will
be used to determine the source and sink queue IDs during
widget binding for widget that requires special pin binding.
An example of widget that requires special pin binding is
the smart amplifier widget, its feedback sink pin has to be
connected to a capture DAI copier for codec feedback, while
the other sink pin has to be connected to a host DAI copier.
Pin ID is required during widget binding for correct route setup.
Conversely, the pin ID for 'generic' pins is not defined in the
topology and will be allocated by the kernel dynamically. When
only one pin is supported, the pin ID shall always be zero. When
more than one pin is supported, the pin ID is determined with the
ID allocation mechanism in the kernel.

Jakub reported that the addition of the "network_byte_order"
member in struct nla_policy increases size of 32bit platforms.
Instead of scraping the bit from elsewhere Johannes suggested
to add explicit NLA_BE types instead, so do this here.
NLA_POLICY_MAX_BE() macro is removed again, there is no need
for it: NLA_POLICY_MAX(NLA_BE.., ..) will do the right thing.
NLA_BE64 can be added later.

In two recent run-time memcpy() bound checking bug reports (NFS[1] and
JFS[2]), the _detection_ was working correctly (in the sense that the
requested copy size was larger than the destination field size), but
the _warning text_ was showing the destination field size as SIZE_MAX
("unknown size"). This should be impossible, since the detection function
will explicitly give up if the destination field size is unknown. For
example, the JFS warning was:
memcpy: detected field-spanning write (size 132) of single field "ip->i_link" at fs/jfs/namei.c:950 (size 18446744073709551615)
Other cases of this warning (e.g.[3]) have reported correctly,
and the reproducer only happens under GCC (at least 10.2 and 12.1),
so this currently appears to be a GCC bug. Explicitly capturing the
__builtin_object_size() results in const temporary variables fixes the
report. For example, the JFS reproducer now correctly reports the field
size (128):
memcpy: detected field-spanning write (size 132) of single field "ip->i_link" at fs/jfs/namei.c:950 (size 128)
Examination of the .text delta (which is otherwise identical), shows
the literal value used in the report changing:
- mov $0xffffffffffffffff,%rcx
+ mov $0x80,%ecx

We used to have a report that pte-marker code can be reached even when
uffd-wp is not compiled in for file memories, here:
https://lore.kernel.org/all/YzeR+R6b4bwBlBHh@x1n/T/#u
I just got time to revisit this and found that the root cause is we simply
messed up with the vma check, so that for !PTE_MARKER_UFFD_WP system, we
will allow UFFDIO_REGISTER of MINOR & WP upon shmem as the check was
wrong:
if (vm_flags & VM_UFFD_MINOR)
return is_vm_hugetlb_page(vma) || vma_is_shmem(vma);
Where we'll allow anything to pass on shmem as long as minor mode is
requested.
Axel did it right when introducing minor mode but I messed it up in
b1f9e876862d when moving code around. Fix it.

AudioReach Modules can connect to other modules using source and
destination port, and each module in theory can support up to 255 port
connections. But in practice this limit is at max 8 ports at a time.
So add support for allowing multiple port connections.
This support is needed for more detailed graphs like ECNS, speaker
protection and so.

Implement suspend/resume() operations for component drivers. For most
scenarios, the PM flow is similar to standard streaming one, except for
the part where the position register are being saved and the lack of PCM
pages freeing. To reduce code duplication, all avs_dai_suspend_XXX() and
avs_dai_resume_XXX() functions reuse their non-PM equivalents.
Given that path binding/unbinding happens only in FE part of the stream,
the order of suspend() goes:
1. hw_free() all FE DAIs, paths are unbound here
2. hw_free() all BE DAIs
Consequently, for resume() its:
1. hw_params() all BE DAIs
2. hw_params() all FE DAIs, paths are bound here
3. prepare() all BE DAIs
4. prepare() all FE DAIs
As component->suspend/resume() do not provide substream pointer, store
it ourselves so that the PM flow has all the necessary information to
proceed.

mlx5_cmd_cleanup_async_ctx should return only after all its callback
handlers were completed. Before this patch, the below race between
mlx5_cmd_cleanup_async_ctx and mlx5_cmd_exec_cb_handler was possible and
lead to a use-after-free:
1. mlx5_cmd_cleanup_async_ctx is called while num_inflight is 2 (i.e.
elevated by 1, a single inflight callback).
2. mlx5_cmd_cleanup_async_ctx decreases num_inflight to 1.
3. mlx5_cmd_exec_cb_handler is called, decreases num_inflight to 0 and
is about to call wake_up().
4. mlx5_cmd_cleanup_async_ctx calls wait_event, which returns
immediately as the condition (num_inflight == 0) holds.
5. mlx5_cmd_cleanup_async_ctx returns.
6. The caller of mlx5_cmd_cleanup_async_ctx frees the mlx5_async_ctx
object.
7. mlx5_cmd_exec_cb_handler goes on and calls wake_up() on the freed
object.
Fix it by syncing using a completion object. Mark it completed when
num_inflight reaches 0.

dm-rq implements ->end_io callback for request issued to underlying queue,
and it isn't passthrough request.
Commit ab3e1d3bbab9 ("block: allow end_io based requests in the completion
batch handling") doesn't clear rq->bio and rq->__data_len for request
with ->end_io in blk_mq_end_request_batch(), and this way is actually
dangerous, but so far it is only for nvme passthrough request.
dm-rq needs to clean up remained bios in case of partial completion,
and req->bio is required, then use-after-free is triggered, so the
underlying clone request can't be completed in blk_mq_end_request_batch.
Fix panic by not adding such request into batch list, and the issue
can be triggered simply by exposing nvme pci to dm-mpath simply.

Move the gfn_to_pfn_cache lock initialization to another helper and
call the new helper during VM/vCPU creation. There are race
conditions possible due to kvm_gfn_to_pfn_cache_init()'s
ability to re-initialize the cache's locks.
For example: a race between ioctl(KVM_XEN_HVM_EVTCHN_SEND) and
kvm_gfn_to_pfn_cache_init() leads to a corrupted shinfo gpc lock.

Rename "cache_init" and "cache_destroy" to activate+deactivate to
avoid implying that the cache really is destroyed/freed.
Note, there more races in the newly named kvm_gpc_activate() that will
be addressed separately.

To keep backward compatibility we used to leave attribute parsing
to the family if no policy is specified. This becomes tedious as
we move to more strict validation. Families must define reject all
policies if they don't want any attributes accepted.
Piggy back on the resv_start_op field as the switchover point.
AFAICT only ethtool has added new commands since the resv_start_op
was defined, and it has per-op policies so this should be a no-op.
Nonetheless the patch should still go into v6.1 for consistency.

IMU is a new firmware for GFX11.
There are four means by which firmware version can be queried
from the driver: device attributes, vf2pf, debugfs,
and the AMDGPU_INFO_FW_VERSION option in the amdgpu info ioctl.
Add IMU as an option for those four methods.
V2: Added debugfs

As Shakeel explains the commit under Fixes had the unintended
side-effect of no longer pre-loading the cached memory allowance.
Even tho we previously dropped the first packet received when
over memory limit - the consecutive ones would get thru by using
the cache. The charging was happening in batches of 128kB, so
we'd let in 128kB (truesize) worth of packets per one drop.
After the change we no longer force charge, there will be no
cache filling side effects. This causes significant drops and
connection stalls for workloads which use a lot of page cache,
since we can't reclaim page cache under GFP_NOWAIT.
Some of the latency can be recovered by improving SACK reneg
handling but nowhere near enough to get back to the pre-5.15
performance (the application I'm experimenting with still
sees 5-10x worst latency).
Apply the suggested workaround of using GFP_ATOMIC. We will now
be more permissive than previously as we'll drop _no_ packets
in softirq when under pressure. But I can't think of any good
and simple way to address that within networking.

We no longer need at least 64 bytes of random seed to permit the early
crng init to complete. The RNG is now based on Blake2s, so reduce the
EFI seed size to the Blake2s hash size, which is sufficient for our
purposes.
While at it, drop the READ_ONCE(), which was supposed to prevent size
from being evaluated after seed was unmapped. However, this cannot
actually happen, so READ_ONCE() is unnecessary here.
