instead it uses the shadow pin_sense which is read at the first time.

It is meaningless to check the shadow pin_sense a couple of times,

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.

ASoC: sprd: Add reserved DMA memory support

For Spreadtrum audio platform driver, it need allocate a larger DMA buffer
dynamically to copy audio data between userspace and kernel space, but that
will increase the risk of memory allocation failure especially the system

To make sure the audio can work in this scenario, we usually reserve one
region of memory to be used as a shared pool of DMA buffers for the
platform component. So add of_reserved_mem_device_init_by_idx() function

  3966c3feca3f ("x86/perf/amd: Remove need to check "running" bit in NMI handler")

              ...
              x86_pmu_disable_event(event)
            }

            __clear_bit(hwc->idx, cpuc->active_mask);

Fixing this by disabling the event itself before setting
off the PEBS bit.

ASoC: Intel: kbl_da7219_max98357a: Map BTN_0 to KEY_PLAYPAUSE

On kbl_rt5663_max98927, commit 38a5882e4292
    ("ASoC: Intel: kbl_rt5663_max98927: Map BTN_0 to KEY_PLAYPAUSE")
    This key pair mapping to play/pause when playing Youtube

The Android 3.5mm Headset jack specification mentions that BTN_0 should
be mapped to KEY_MEDIA, but this is less logical than KEY_PLAYPAUSE,
which has much broader userspace support.

For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle
play/pause of videos and audio, but does not handle KEY_MEDIA.

Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the
new USB headset spec requires KEY_PLAYPAUSE for BTN_0.
https://source.android.com/devices/accessories/headset/usb-headset-spec

The same fix is required on Chrome kbl_da7219_max98357a.

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
'perf report --itrace=i1000i' for decoding tracing data.

If neither the 'b' flag (synthesize branches events) nor 'l' flag
(synthesize last branch entries) are specified to option '--itrace',
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()

    + process_finished_round()
      + ordered_events__flush()
        + __ordered_events__flush()

          + 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):

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.

5 years agoperf/x86/amd: Update generic hardware cache events for Family 17h
Kim Phillips [Thu, 2 May 2019 15:29:47 +0000 (15:29 +0000)]
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.

suspended adapter. Switch to dev_WARN_ONCE to fix both issues. Drawback
is that we don't see if multiple drivers are trying to transfer while
