ALSA: hdea/realtek - Headset fixup for System76 Gazelle (gaze14)
On the System76 Gazelle (gaze14), there is a headset microphone input
attached to 0x1a that does not have a jack detect. In order to get it
working, the pin configuration needs to be set correctly, and the
ALC269_FIXUP_HEADSET_MODE_NO_HP_MIC fixup needs to be applied. This is
identical to the patch already applied for the System76 Darter Pro
(darp5).

ALSA: hda/hdmi - Consider eld_valid when reporting jack event
On the machines with AMD GPU or Nvidia GPU, we often meet this issue:
after s3, there are 4 HDMI/DP audio devices in the gnome-sound-setting
even there is no any monitors plugged.
When this problem happens, we check the /proc/asound/cardX/eld#N.M, we
will find the monitor_present=1, eld_valid=0.
The root cause is BIOS or GPU driver makes the PRESENCE valid even no
monitor plugged, and of course the driver will not get the valid
eld_data subsequently.
In this situation, we should not report the jack_plugged event, to do
so, let us change the function hdmi_present_sense_via_verbs(). In this
function, it reads the pin_sense via snd_hda_pin_sense(), after
calling this function, the jack_dirty is 0, and before exiting
via_verbs(), we change the shadow pin_sense according to both
monitor_present and eld_valid, then in the snd_hda_jack_report_sync(),
since the jack_dirty is still 0, it will report jack event according
to this modified shadow pin_sense.
After this change, the driver will not report Jack_is_plugged event
through hdmi_present_sense_via_verbs() if monitor_present is 1 and
eld_valid is 0.

The driver will check the monitor presence when resuming from suspend,

will be set to 0. But hdmi_repoll_work() is enabled in these 3

since the jack_dirty is 0 now, It does not read the register anymore,
instead it uses the shadow pin_sense which is read at the first time.

ASoC: Updates for v5.2
This is a pretty huge set of changes, it's been a pretty active release
all round but the big thing with this release is the Sound Open Firmware
changes from Intel, providing another DSP framework for use with the
DSPs in their SoCs. This one works with the firmware of the same name
which is free software (unlike the previous DSP firmwares and framework)
and there has been some interest in adoption by other systems already so
hopefully we will see adoption by other vendors in the future.
Other highlights include:
- Support for MCLK/sample rate ratio setting in the generic cards.
- Support for pin switches in the generic cards.
- A big set of improvements to the TLV320AIC32x4 drivers from Annaliese
McDermond.
- New drivers for Freescale audio mixers, several Intel machines,
several Mediatek machines, Meson G12A, Sound Open Firmware and
Spreadtrum compressed audio and DMA devices.

To make sure the audio can work in this scenario, we usually reserve one

The Android 3.5mm Headset jack specification mentions that BTN_0 should

which has much broader userspace support.
For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle

Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the

ASoC: SOF: intel: hda: add hw_params_upon_resume flag for hda stream
The prepare() ioctl for BE dai link gets called both
when the stream is started and when it is resumed from
suspend. SOF uses this ioctl to set the hw params
again only if the stream has been suspended.
When the stream is started, the hw_params ioctl gets called
before prepare() and hw_params is set for the BE dai link.
So the prepare call does not need to do anything further.
When the stream resumes after system suspend, SOF requires
that the hw_params be set again for the BE dai. In order
to determine which streams should set the hw params
during prepare(), an internal flag called "hw_params_upon_resume"
is introduced in struct sof_intel_hda_stream. The flag is set
for hda streams when the sof device suspends and is
cleared after hw_params is set.

The IPC implementation in SOF requires sending IPCs serially: we should

snd_pcm_period_elapsed() can be called in interrupt context before
IRQ_HANDLED is returned. When the PCM is done draining, a STOP
IPC will then be sent, which breaks the expectation that IPCs are

perf cs-etm: Always allocate memory for cs_etm_queue::prev_packet
Robert Walker reported a segmentation fault is observed when process
CoreSight trace data; this issue can be easily reproduced by the command

If neither the 'b' flag (synthesize branches events) nor 'l' flag

cs_etm_queue::prev_packet will not been initialised. After merging the
code to support exception packets and sample flags, there introduced a
number of uses of cs_etm_queue::prev_packet without checking whether it
is valid, for these cases any accessing to uninitialised prev_packet
will cause crash.
As cs_etm_queue::prev_packet is used more widely now and it's already
hard to follow which functions have been called in a context where the
validity of cs_etm_queue::prev_packet has been checked, this patch
always allocates memory for cs_etm_queue::prev_packet.

The sample precentage is a bit low.....
The GUI always fails in the FINISHED_ROUND event (68) and does not
indicate the reason why.
When happened is the following. Perf report calls a lot of functions and
down deep when a FINISHED_ROUND event is processed, these functions are
called:
perf_session__process_event()
+ perf_session__process_user_event()
+ process_finished_round()
+ ordered_events__flush()
+ __ordered_events__flush()
+ do_flush()
+ ordered_events__deliver_event()
+ perf_session__deliver_event()
+ machine__deliver_event()
+ perf_evlist__deliver_event()
+ process_sample_event()
+ hist_entry_iter_add() --> only called in GUI case!!!
+ hist_iter__report__callback()
+ symbol__inc_addr_sample()
Now this functions runs out of memory and
returns -ENOMEM. This is reported all the way up
until function
perf_session__process_event() returns to its caller, where -ENOMEM is
changed to -EINVAL and processing stops:
if ((skip = perf_session__process_event(session, event, head)) < 0) {
pr_err("%#" PRIx64 " [%#x]: failed to process type: %d\n",
head, event->header.size, event->header.type);
err = -EINVAL;
goto out_err;
}
This occurred in the FINISHED_ROUND event when it has to process some
10000 entries and ran out of memory.
This patch indicates the root cause and displays it in the status line
of ther perf report GUI.
Output before (on GUI status line):
0xf4198 [0x8]: failed to process type: 68
Output after:
0xf4198 [0x8]: failed to process type: 68 [not enough memory]
Committer notes:
the 'skip' variable needs to be initialized to -EINVAL, so that when the
size is less than sizeof(struct perf_event_attr) we avoid this valid

So, since RUSAGE_THREAD is available as a define, check for that and

So, since RUSAGE_THREAD is available as a define in the system headers,
check if it is defined in the 'perf bench numa' sources and define it if
not.
Now it builds and I have to figure out if the problem reported by Vineet
only takes place if we have libelf or some other library available.

i2c: Prevent runtime suspend of adapter when Host Notify is required
Multiple users have reported their Synaptics touchpad has stopped
working between v4.20.1 and v4.20.2 when using SMBus interface.
The culprit for this appeared to be commit
c5eb1190074c ("PCI / PM: Allow
runtime PM without callback functions") that fixed the runtime PM for
i2c-i801 SMBus adapter. Those Synaptics touchpad are using i2c-i801
for SMBus communication and testing showed they are able to get back
working by preventing the runtime suspend of adapter.
Normally when i2c-i801 SMBus adapter transmits with the client it resumes
before operation and autosuspends after.
However, if client requires SMBus Host Notify protocol, what those
Synaptics touchpads do, then the host adapter must not go to runtime
suspend since then it cannot process incoming SMBus Host Notify commands
the client may send.
Fix this by keeping I2C/SMBus adapter active in case client requires
Host Notify.

perf/x86/amd: Update generic hardware cache events for Family 17h
Add a new amd_hw_cache_event_ids_f17h assignment structure set
for AMD families 17h and above, since a lot has changed. Specifically:
L1 Data Cache
The data cache access counter remains the same on Family 17h.
For DC misses, PMCx041's definition changes with Family 17h,
so instead we use the L2 cache accesses from L1 data cache
misses counter (PMCx060,umask=0xc8).
For DC hardware prefetch events, Family 17h breaks compatibility
for PMCx067 "Data Prefetcher", so instead, we use PMCx05a "Hardware
Prefetch DC Fills."
L1 Instruction Cache
PMCs 0x80 and 0x81 (32-byte IC fetches and misses) are backward
compatible on Family 17h.
For prefetches, we remove the erroneous PMCx04B assignment which
counts how many software data cache prefetch load instructions were
dispatched.
LL - Last Level Cache
Removing PMCs 7D, 7E, and 7F assignments, as they do not exist
on Family 17h, where the last level cache is L3. L3 counters
can be accessed using the existing AMD Uncore driver.
Data TLB
On Intel machines, data TLB accesses ("dTLB-loads") are assigned
to counters that count load/store instructions retired. This
is inconsistent with instruction TLB accesses, where Intel
implementations report iTLB misses that hit in the STLB.
Ideally, dTLB-loads would count higher level dTLB misses that hit
in lower level TLBs, and dTLB-load-misses would report those
that also missed in those lower-level TLBs, therefore causing
a page table walk. That would be consistent with instruction
TLB operation, remove the redundancy between dTLB-loads and
L1-dcache-loads, and prevent perf from producing artificially
low percentage ratios, i.e. the "0.01%" below:
42,550,869 L1-dcache-loads
41,591,860 dTLB-loads
4,802 dTLB-load-misses # 0.01% of all dTLB cache hits
7,283,682 L1-dcache-stores
7,912,392 dTLB-stores
310 dTLB-store-misses
On AMD Families prior to 17h, the "Data Cache Accesses" counter is
used, which is slightly better than load/store instructions retired,
but still counts in terms of individual load/store operations
instead of TLB operations.
So, for AMD Families 17h and higher, this patch assigns "dTLB-loads"
to a counter for L1 dTLB misses that hit in the L2 dTLB, and
"dTLB-load-misses" to a counter for L1 DTLB misses that caused
L2 DTLB misses and therefore also caused page table walks. This
results in a much more accurate view of data TLB performance:
60,961,781 L1-dcache-loads
4,601 dTLB-loads
963 dTLB-load-misses # 20.93% of all dTLB cache hits
Note that for all AMD families, data loads and stores are combined
in a single accesses counter, so no 'L1-dcache-stores' are reported
separately, and stores are counted with loads in 'L1-dcache-loads'.
Also note that the "% of all dTLB cache hits" string is misleading
because (a) "dTLB cache": although TLBs can be considered caches for
page tables, in this context, it can be misinterpreted as data cache
hits because the figures are similar (at least on Intel), and (b) not
all those loads (technically accesses) technically "hit" at that
hardware level. "% of all dTLB accesses" would be more clear/accurate.
Instruction TLB
On Intel machines, 'iTLB-loads' measure iTLB misses that hit in the
STLB, and 'iTLB-load-misses' measure iTLB misses that also missed in
the STLB and completed a page table walk.
For AMD Family 17h and above, for 'iTLB-loads' we replace the
erroneous instruction cache fetches counter with PMCx084
"L1 ITLB Miss, L2 ITLB Hit".
For 'iTLB-load-misses' we still use PMCx085 "L1 ITLB Miss,
L2 ITLB Miss", but set a 0xff umask because without it the event
does not get counted.
Branch Predictor (BPU)
PMCs 0xc2 and 0xc3 continue to be valid across all AMD Families.
Node Level Events
Family 17h does not have a PMCx0e9 counter, and corresponding counters
have not been made available publicly, so for now, we mark them as
unsupported for Families 17h and above.

Two: We don't see which driver tried to transfer something with a

is that we don't see if multiple drivers are trying to transfer while

better than a high CPU load because a really broken driver might try to

PCI/LINK: Add Kconfig option (default off)
e8303bb7a75c ("PCI/LINK: Report degraded links via link bandwidth
notification") added dmesg logging whenever a link changes speed or width
to a state that is considered degraded. Unfortunately, it cannot
differentiate signal integrity-related link changes from those
intentionally initiated by an endpoint driver, including drivers that may
live in userspace or VMs when making use of vfio-pci. Some GPU drivers
actively manage the link state to save power, which generates a stream of
messages like this:
vfio-pci 0000:07:00.0: 32.000 Gb/s available PCIe bandwidth, limited by 2.5 GT/s x16 link at 0000:00:02.0 (capable of 64.000 Gb/s with 5 GT/s x16 link)
Since we can't distinguish the intentional changes from the signal
integrity issues, leave the reporting turned off by default. Add a Kconfig
option to turn it on if desired.

ASoC: da7219: Use clk_round_rate to handle enabled bclk/wclk case
For some platforms where DA7219 is the DAI clock master, BCLK/WCLK
will be set and enabled prior to the codec's hw_params() function
being called. It is possible the platform requires a different
BCLK configuration than would be chosen by hw_params(), for
example S16_LE format needed with a 64-bit frame to satisfy certain
devices using the clocks.
To handle those kinds of scenarios, the use of clk_round_rate() is
now employed as part of hw_params(). If BCLK is already enabled
then this function will just return the currently set rate, if it
is valid for the desired frame size, so the subsequent call to
clk_set_rate() will succeed and nothing changes with regards to
clocking. In addition the specific BCLK & WCLK recalc_rate()
implementations needed updating to always give back a real value,
as those functions are called as part of the clk init code and a
real value is needed for the clk_round_rate() call to work as
expected.
