The SOF topology loading function sets the device name for the platform
component link. This should be unset when unloading the topology,
otherwise a machine driver unbind/bind or reprobe would complain about
an invalid component as having both its component name and of_node set:
mt8186_mt6366 sound: ASoC: Both Component name/of_node are set for AFE_SOF_DL1
mt8186_mt6366 sound: error -EINVAL: Cannot register card
mt8186_mt6366 sound: probe with driver mt8186_mt6366 failed with error -22
This happens with machine drivers that set the of_node separately.
Clear the SOF link platform name in the topology unload callback.

Now that we shrank struct file by 24 bytes we still have a 4 byte hole.
If we move struct file_ra_state into the union and f_iocb_flags out of
the union we close that whole and bring down struct file to 192 bytes.
Which means struct file is 3 cachelines and we managed to shrink it by
40 bytes this cycle.
I've tried to audit all codepaths that use f_ra and none of them seem to
rely on it in file->f_op->release() and never have since commit
1da177e4c3 ("Linux-2.6.12-rc2").

We do embedd struct fown_struct into struct file letting it take up 32
bytes in total. We could tweak struct fown_struct to be more compact but
really it shouldn't even be embedded in struct file in the first place.
Instead, actual users of struct fown_struct should allocate the struct
on demand. This frees up 24 bytes in struct file.
That will have some potentially user-visible changes for the ownership
fcntl()s. Some of them can now fail due to allocation failures.
Practically, that probably will almost never happen as the allocations
are small and they only happen once per file.
The fown_struct is used during kill_fasync() which is used by e.g.,
pipes to generate a SIGIO signal. Sending of such signals is conditional
on userspace having set an owner for the file using one of the F_OWNER
fcntl()s. Such users will be unaffected if struct fown_struct is
allocated during the fcntl() call.
There are a few subsystems that call __f_setown() expecting
file->f_owner to be allocated:
(1) tun devices
file->f_op->fasync::tun_chr_fasync()
-> __f_setown()
There are no callers of tun_chr_fasync().
(2) tty devices
file->f_op->fasync::tty_fasync()
-> __tty_fasync()
-> __f_setown()
tty_fasync() has no additional callers but __tty_fasync() has. Note
that __tty_fasync() only calls __f_setown() if the @on argument is
true. It's called from:
file->f_op->release::tty_release()
-> tty_release()
-> __tty_fasync()
-> __f_setown()
tty_release() calls __tty_fasync() with @on false
=> __f_setown() is never called from tty_release().
=> All callers of tty_release() are safe as well.
file->f_op->release::tty_open()
-> tty_release()
-> __tty_fasync()
-> __f_setown()
__tty_hangup() calls __tty_fasync() with @on false
=> __f_setown() is never called from tty_release().
=> All callers of __tty_hangup() are safe as well.
From the callchains it's obvious that (1) and (2) end up getting called
via file->f_op->fasync(). That can happen either through the F_SETFL
fcntl() with the FASYNC flag raised or via the FIOASYNC ioctl(). If
FASYNC is requested and the file isn't already FASYNC then
file->f_op->fasync() is called with @on true which ends up causing both
(1) and (2) to call __f_setown().
(1) and (2) are the only subsystems that call __f_setown() from the
file->f_op->fasync() handler. So both (1) and (2) have been updated to
allocate a struct fown_struct prior to calling fasync_helper() to
register with the fasync infrastructure. That's safe as they both call
fasync_helper() which also does allocations if @on is true.
The other interesting case are file leases:
(3) file leases
lease_manager_ops->lm_setup::lease_setup()
-> __f_setown()
Which in turn is called from:
generic_add_lease()
-> lease_manager_ops->lm_setup::lease_setup()
-> __f_setown()
So here again we can simply make generic_add_lease() allocate struct
fown_struct prior to the lease_manager_ops->lm_setup::lease_setup()
which happens under a spinlock.
With that the two remaining subsystems that call __f_setown() are:
(4) dnotify
(5) sockets
Both have their own custom ioctls to set struct fown_struct and both
have been converted to allocate a struct fown_struct on demand from
their respective ioctls.
Interactions with O_PATH are fine as well e.g., when opening a /dev/tty
as O_PATH then no file->f_op->open() happens thus no file->f_owner is
allocated. That's fine as no file operation will be set for those and
the device has never been opened. fcntl()s called on such things will
just allocate a ->f_owner on demand. Although I have zero idea why'd you
care about f_owner on an O_PATH fd.

resctrl_arch_system_num_rmid_idx() / snc_nodes_per_l3_cache

In some cases the sink can reset itself after it was configured into MST
mode, without the driver noticing the disconnected state. For instance
the reset may happen in the middle of a modeset, or the (long) HPD pulse
generated may be not long enough for the encoder detect handler to
observe the HPD's deasserted state. In this case the sink's DPCD
register programmed to enable MST will be reset, while the driver still
assumes MST is still enabled. Detect this condition, which will tear
down and recreate/re-enable the MST topology.
v2:
- Add a code comment about adjusting the expected DP_MSTM_CTRL register
value for SST + SideBand. (Suraj, Jani)
- Print a debug message about detecting the link reset. (Jani)
- Verify the DPCD MST state only if it wasn't already determined that
the sink is disconnected.

Reference frame compression is a feature added in the G2 decoder to
compress frame buffers so that the bandwidth of storing/loading
reference frames can be reduced, especially with high resolution decoded
streams.
The impact of compressed frames is confirmed when using perf to monitor
the number of memory accesses with or without the compression feature.
The following command:
perf stat -a -e \
imx8_ddr0/cycles/,imx8_ddr0/read-cycles/,imx8_ddr0/write-cycles/ \
gst-launch-1.0 filesrc \
location=Jockey_3840x2160_120fps_420_8bit_HEVC_RAW.hevc ! queue ! \
h265parse ! v4l2slh265dec ! video/x-raw,format=NV12 ! fakesink
Gives us these results without the compression feature:
Performance counter stats for 'system wide':
1711300345 imx8_ddr0/cycles/
892207924 imx8_ddr0/read-cycles/
1291785864 imx8_ddr0/write-cycles/
13.760048353 seconds time elapsed
With the compression feature:
Performance counter stats for 'system wide':
274526799 imx8_ddr0/cycles/
453120194 imx8_ddr0/read-cycles/
833391434 imx8_ddr0/write-cycles/
18.257831534 seconds time elapsed
As expected the number of read/write cycles are really lower when
compression is used.
Since storing the compression data requires more memory a module
parameter named 'hevc_use_compression' is used to enable/disable
this feature and, by default, compression isn't used.
Enabling the compression feature means that the output-frames of the
decoder
are stored with a specific compression pixel-format. Since this
pixel format is unknown, this patch restrains the compression feature
usage to the cases where post-processor pixel-formats (NV12 or NV15)
are selected by the applications.
The Fluster compliance HEVC test suite score is still 141/147 with this
patch.

The devm_clk_get_enabled() helpers:
- call devm_clk_get()
- call clk_prepare_enable() and register what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
This simplifies the code and avoids the calls to clk_disable_unprepare().

For flush request, md has a special flush handling to merge concurrent
flush request into single one, however, the whole mechanism is based on
a disk level spin_lock 'mddev->lock'. And fsync can be called quite
often in some user cases, for consequence, spin lock from IO fast path can
cause performance degradation.
Fortunately, the block layer already has flush handling to merge
concurrent flush request, and it only acquires hctx level spin lock. (see
details in blk-flush.c)
This patch removes the flush handling in md, and converts to use general
block layer flush handling in underlying disks.
Flush test for 4 nvme raid10:
start 128 threads to do fsync 100000 times, on arm64, see how long it
takes.
Test script:
void* thread_func(void* arg) {
int fd = *(int*)arg;
for (int i = 0; i < FSYNC_COUNT; i++) {
fsync(fd);
}
return NULL;
}
int main() {
int fd = open("/dev/md0", O_RDWR);
if (fd < 0) {
perror("open");
exit(1);
}
pthread_t threads[THREADS];
struct timeval start, end;
gettimeofday(&start, NULL);
for (int i = 0; i < THREADS; i++) {
pthread_create(&threads[i], NULL, thread_func, &fd);
}
for (int i = 0; i < THREADS; i++) {
pthread_join(threads[i], NULL);
}
gettimeofday(&end, NULL);
close(fd);
long long elapsed = (end.tv_sec - start.tv_sec) * 1000000LL + (end.tv_usec - start.tv_usec);
printf("Elapsed time: %lld microseconds\n", elapsed);
return 0;
}
Test result: about 10 times faster:
Before this patch: 50943374 microseconds
After this patch: 5096347 microseconds

Intel Wired LAN Driver Updates 2024-08-26 (ice)
This series contains updates to ice driver only.
Jake implements and uses rd32_poll_timeout to replace a jiffies loop for
calling ice_sq_done. The rd32_poll_timeout() function is designed to allow
simplifying other places in the driver where we need to read a register
until it matches a known value.
Jake, Bruce, and Przemek update ice_debug_cq() to be more robust, and more
useful for tracing control queue messages sent and received by the device
driver.
Jake rewords several commands in the ice_control.c file which previously
referred to the "Admin queue" when they were actually generic functions
usable on any control queue.
Jake removes the unused and unnecessary cmd_buf array allocation for send
queues. This logic originally was going to be useful if we ever implemented
asynchronous completion of transmit messages. This support is unlikely to
materialize, so the overhead of allocating a command buffer is unnecessary.
Sergey improves the log messages when the ice driver reports that the NVM
version on the device is not supported by the driver. Now, these messages
include both the discovered NVM version and the requested/expected NVM
version.
Aleksandr Mishin corrects overallocation of memory related to adding
scheduler nodes.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: Adjust over allocation of memory in ice_sched_add_root_node() and ice_sched_add_node()
ice: Report NVM version numbers on mismatch during load
ice: remove unnecessary control queue cmd_buf arrays
ice: reword comments referring to control queues
ice: stop intermixing AQ commands/responses debug dumps
ice: do not clutter debug logs with unused data
ice: improve debug print for control queue messages
ice: implement and use rd32_poll_timeout for ice_sq_done timeout

KSZ8895/KSZ8864 is a switch family developed before KSZ8795 and after
KSZ8863, so it shares some registers and functions in those switches.
KSZ8895 has 5 ports and so is more similar to KSZ8795.
KSZ8864 is a 4-port version of KSZ8895. The first port is removed
while port 5 remains as a host port.

sctp_sf_do_5_2_4_dupcook() currently calls security_sctp_assoc_request()
on new_asoc, but as it turns out, this association is always discarded
and the LSM labels never get into the final association (asoc).
This can be reproduced by having two SCTP endpoints try to initiate an
association with each other at approximately the same time and then peel
off the association into a new socket, which exposes the unitialized
labels and triggers SELinux denials.
Fix it by calling security_sctp_assoc_request() on asoc instead of
new_asoc. Xin Long also suggested limit calling the hook only to cases
A, B, and D, since in cases C and E the COOKIE ECHO chunk is discarded
and the association doesn't enter the ESTABLISHED state, so rectify that
as well.
One related caveat with SELinux and peer labeling: When an SCTP
connection is set up simultaneously in this way, we will end up with an
association that is initialized with security_sctp_assoc_request() on
both sides, so the MLS component of the security context of the
association will get swapped between the peers, instead of just one side
setting it to the other's MLS component. However, at that point
security_sctp_assoc_request() had already been called on both sides in
sctp_sf_do_unexpected_init() (on a temporary association) and thus if
the exchange didn't fail before due to MLS, it won't fail now either
(most likely both endpoints have the same MLS range).
Tested by:
- reproducer from https://src.fedoraproject.org/tests/selinux/pull-request/530
- selinux-testsuite (https://github.com/SELinuxProject/selinux-testsuite/)
- sctp-tests (https://github.com/sctp/sctp-tests) - no tests failed
that wouldn't fail also without the patch applied
