The PTT trace collects PCIe TLP headers from the PCIe link and don't
have the ability to exclude certain context. It doesn't support itrace
as well. So replace PERF_PMU_CAP_ITRACE with PERF_PMU_CAP_NO_EXCLUDE.
This will greatly save the storage of final data. Tested tracing idle
link for ~15s, without this patch we'll collect ~28.682MB data for
additional information and with this patch it reduced to ~0.226MB.

The PTT can only filter the traced TLP headers by the Root Ports or the
Requester ID of the Endpoint, which are located on the same PCIe core of
the PTT device. The filter value used is derived from the BDF number of
the supported Root Port or the Endpoint. It's not friendly enough for the
users since it requires the user to be familiar enough with the platform
and calculate the filter value manually.
This patch export the available filters through sysfs. Each available
filters is presented as an individual file with the name of the BDF
number of the related PCIe device. The files are created under
$(PTT PMU dir)/available_root_port_filters and
$(PTT PMU dir)/available_requester_filters respectively. The filter
value can be known by reading the related file.
Then the users can easily know the available filters for trace and get
the filter values without calculating.

The PCIe devices supported by the PTT trace can be removed/rescanned by
hotplug or through sysfs. Add support for dynamically updating the
available filter list by registering a PCI bus notifier block. Then user
can always get latest information about available tracing filters and
driver can block the invalid filters of which related devices no longer
exist in the system.

For filenames that begin with . and are between 2 and 5 characters long,
UDF charset conversion code would read uninitialized memory in the
output buffer. The only practical impact is that the name may be prepended a
"unification hash" when it is not actually needed but still it is good
to fix this.

The main change is to adjust RX calibration groups from {0,1,2,3} to {0,2}
in 5 GHz, so reduce elements from 4 to 2, and use index to iterate them.
Meanwhile, always do RX narrowband calibration (ID_NBRXK) for each group.
NCTL is used to assist IQK, so also update NCTL to 0x6 along with internal

Without this patch, firmware only track beacons for port 0 and since
we will always start AP on port 0, this results in misbehavior of
power saving mode on other ports after AP stops.
The "default port" H2C command is used to notify which port should
firmware track. Update the correct settings to firmware so power
saving mode can work properly.

to recognize that there are multiple packets and fetches only one.

In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through
nl80211_tx_control_port() and triggers wake_tx_queue() in the driver.
Then, it sends nl80211_new_key() to configure a new key in mac80211.
However, in wake_tx_queue(), a workqueue is used to process the tx packet,
which might cause the driver to process the EAPOL packet later than
nl80211_new_key(). As a result, the EAPOL 4/4 packet is dropped by mac80211
due to the rekey configuration being finished. The EAPOL packets belongs to
VO packets that need high priority. Therefore, we process VO packets
directly without workqueue to ensure that packets can process immediately.
VO is normally used by voice application that is low traffic load and low
latency, that doesn't affect user experience.
We test iperf with VO packets(iperf3 -P4 -u -b 10000M -S 0xdf)

For combo chips, antennas were controlled by bluetooth only during
power on. If WiFi wish to do transmission, notification to the coexistence
module are required. Previously we only do this before authentication.
To allow transmission before auth, such as management TX, now we start
the initiation of coexistence earlier so antennas are shared between
WiFi and bluetooth after set_channel(), and frames could then be sent.

We currently allow to create perf link for program with
expected_attach_type == BPF_TRACE_KPROBE_MULTI.
This will cause crash when we call helpers like get_attach_cookie or
get_func_ip in such program, because it will call the kprobe_multi's
version (current->bpf_ctx context setup) of those helpers while it
expects perf_link's current->bpf_ctx context setup.
Making sure that we use BPF_TRACE_KPROBE_MULTI expected_attach_type
only for programs attaching through kprobe_multi link.

When building a kernel with LLVM=1, LLVM_IAS=0 and CONFIG_KASAN=y, LLVM
leaves DWARF tags for the "asan.module_ctor" & co symbols. In turn,
pahole creates BTF_KIND_FUNC entries for these and this makes the BTF
metadata validation fail because they contain a dot.
In a dramatic turn of event, this BTF verification failure can cause
the netfilter_bpf initialization to fail, causing netfilter_core to
free the netfilter_helper hashmap and netfilter_ftp to trigger a
use-after-free. The risk of u-a-f in netfilter will be addressed
separately but the existence of "asan.module_ctor" debug info under some
build conditions sounds like a good enough reason to accept functions
that contain dots in BTF.
Although using only LLVM=1 is the recommended way to compile clang-based
kernels, users can certainly do LLVM=1, LLVM_IAS=0 as well and we still
try to support that combination according to Nick. To clarify:
- > v5.10 kernel, LLVM=1 (LLVM_IAS=0 is not the default) is recommended,
but user can still have LLVM=1, LLVM_IAS=0 to trigger the issue
- <= 5.10 kernel, LLVM=1 (LLVM_IAS=0 is the default) is recommended in
which case GNU as will be used

This reverts commit 07b679f70d73483930e8d3c293942416d9cd5c13.
This change appears to have broken things...
We now see applications hanging during disk accesses.
e.g.
multi-port virtio-blk device running in h/w (FPGA)
Host running a simple 'fio' test.
[global]
thread=1
direct=1
ioengine=libaio
norandommap=1
group_reporting=1
bs=4K
rw=read
iodepth=128
runtime=1
numjobs=4
time_based
[job0]
filename=/dev/vda
[job1]
filename=/dev/vdb
[job2]
filename=/dev/vdc
...
[job15]
filename=/dev/vdp
i.e. 16 disks; 4 queues per disk; simple burst of 4KB reads
This is repeatedly run in a loop.
After a few, normally <10 seconds, fio hangs.
With 64 queues (16 disks), failure occurs within a few seconds; with 8 queues (2 disks) it may take ~hour before hanging.
Last message:
fio-3.19
Starting 8 threads
Jobs: 1 (f=1): [_(7),R(1)][68.3%][eta 03h:11m:06s]
I think this means at the end of the run 1 queue was left incomplete.
'diskstats' (run while fio is hung) shows no outstanding transactions.
e.g.
$ cat /proc/diskstats
...
252 0 vda 1843140071 0 14745120568 712568645 0 0 0 0 0 3117947 712568645 0 0 0 0 0 0
252 16 vdb 1816291511 0 14530332088 704905623 0 0 0 0 0 3117711 704905623 0 0 0 0 0 0
...
Other stats (in the h/w, and added to the virtio-blk driver ([a]virtio_queue_rq(), [b]virtblk_handle_req(), [c]virtblk_request_done()) all agree, and show every request had a completion, and that virtblk_request_done() never gets called.
e.g.
PF= 0 vq=0 1 2 3
[a]request_count - 839416590 813148916 105586179 84988123
[b]completion1_count - 839416590 813148916 105586179 84988123
[c]completion2_count - 0 0 0 0
PF= 1 vq=0 1 2 3
[a]request_count - 823335887 812516140 104582672 75856549
[b]completion1_count - 823335887 812516140 104582672 75856549
[c]completion2_count - 0 0 0 0
i.e. the issue is after the virtio-blk driver.
This change was introduced in kernel 6.3.0.
I am seeing this using 6.3.3.
If I run with an earlier kernel (5.15), it does not occur.
If I make a simple patch to the 6.3.3 virtio-blk driver, to skip the blk_mq_add_to_batch()call, it does not fail.
e.g.
kernel 5.15 - this is OK
virtio_blk.c,virtblk_done() [irq handler]
if (likely(!blk_should_fake_timeout(req->q))) {
blk_mq_complete_request(req);
}
kernel 6.3.3 - this fails
virtio_blk.c,virtblk_handle_req() [irq handler]
if (likely(!blk_should_fake_timeout(req->q))) {
if (!blk_mq_complete_request_remote(req)) {
if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) {
virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed
}
}
}
If I do, kernel 6.3.3 - this is OK
virtio_blk.c,virtblk_handle_req() [irq handler]
if (likely(!blk_should_fake_timeout(req->q))) {
if (!blk_mq_complete_request_remote(req)) {
virtblk_request_done(req); //force this here...
if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) {
virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed
}
}
}
Perhaps you might like to fix/test/revert this change...

Switch SAMA7G5 clocks to use parent_hw and parent_data. Having
parent_hw instead of parent names improves to clock registration
speed and re-parenting. Extra time saved on registration is
~250us when running at 800MHz.

Add the '-@' DTC option for AT91 boards that have device-tree overlays.
This option populates the '__symbols__' node that contains all the
necessary symbols for supporting device-tree overlays (from bootloader)
on these devices.
This change increases the size of the resulting DTB with ~30%-40%. Below
are the measurements performed v6.4-rc6:
at91-sam9x60_curiosity.dtb 28499 -> 36641 bytes

One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element arrays with flexible-array
members in multiple structures.
Address the following -Wstringop-overflow warnings seen when built
m68k architecture with m5307c3_defconfig configuration:
In function '__put_user_fn',
inlined from 'fillonedir' at fs/readdir.c:170:2:
include/asm-generic/uaccess.h:49:35: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=]

fs/readdir.c:134:25: note: at offset 1 into destination object 'd_name' of size 1

This helps with the ongoing efforts to globally enable
-Wstringop-overflow.
This results in no differences in binary output.
