Geert Uytterhoeven 9f65df9c58 ALSA: firewire-tascam: Fix integer overflow in midi_port_work()
As snd_fw_async_midi_port.consume_bytes is unsigned int, and
NSEC_PER_SEC is 1000000000L, the second multiplication in

    port->consume_bytes * 8 * NSEC_PER_SEC / 31250

always overflows on 32-bit platforms, truncating the result.  Fix this
by precalculating "NSEC_PER_SEC / 31250", which is an integer constant.

Note that this assumes port->consume_bytes <= 16777.

Peter Geis 615d435400 ALSA: hda/tegra: fix tegra-hda on tegra30 soc
Currently hda on tegra30 fails to open a stream with an input/output error.

For example:
speaker-test -Dhw:0,3 -c 2

speaker-test 1.2.2

Playback device is hw:0,3
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 32 to 8192
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
 0 - Front Left
Write error: -5,Input/output error
xrun_recovery failed: -5,Input/output error
Transfer failed: Input/output error

The tegra-hda device was introduced in tegra30 but only utilized in
tegra124 until recent chips. Tegra210/186 work only due to a hardware
change. For this reason it is unknown when this issue first manifested.
Discussions with the hardware team show this applies to all current tegra
chips. It has been resolved in the tegra234, which does not have hda
support at this time.

The explanation from the hardware team is this:
Below is the striping formula referenced from HD audio spec.
   { ((num_channels * bits_per_sample) / number of SDOs) >= 8 }

The current issue is seen because Tegra HW has a problem with boundary
condition (= 8) for striping. The reason why it is not seen on
Tegra210/Tegra186 is because it uses max 2SDO lines. Max SDO lines is
read from GCAP register.

For the given stream (channels = 2, bps = 16);
ratio = (channels * bps) / NSDO = 32 / NSDO;

On Tegra30,      ratio = 32/4 = 8  (FAIL)
On Tegra210/186, ratio = 32/2 = 16 (PASS)
On Tegra194,     ratio = 32/4 = 8  (FAIL) ==> Earlier workaround was
applied for it

If Tegra210/186 is forced to use 4SDO, it fails there as well. So the
behavior is consistent across all these chips.

Applying the fix in [1] universally resolves this issue on tegra30-hda.
Tested on the Ouya game console and the tf201 tablet.

Tegra194")

Peter Geis f4eccc7fea clk: tegra30: Add hda clock default rates to clock driver
Current implementation defaults the hda clocks to clk_m. This causes hda
to run too slow to operate correctly. Fix this by defaulting to pll_p and
setting the frequency to the correct rate.

This matches upstream t124 and downstream t30.

Takashi Iwai 167c9dc84e ALSA: usb-audio: Fix implicit feedback sync setup for Pioneer devices
Pioneer devices have both playback and capture streams sharing the
same iface/altsetting, and those need to be paired as implicit
feedback.  Instead of a half-baked (and broken) static quirk entry,
set up more generically for those devices by checking the number of
endpoints and the attribute of the secondary EP.

Takashi Iwai eae4d054f9 ALSA: usb-audio: Annotate the endpoint index in audioformat
There are devices that have multiple endpoints sharing the same
iface/altset not only for sync but also for the actual streams, and
the audioformat for such an endpoint needs to be handled with the
proper endpoint index; otherwise it confuses the endpoint management.

This patch extends the audioformat to annotate the endpoint index, and
put the proper ep_idx=1 to Pioneer device quirk entries accordingly.

Takashi Iwai 00272c6182 ALSA: usb-audio: Avoid unnecessary interface re-setup
The current endpoint handling assumed (more or less) a unique 1:1
relation between the endpoint and the iface/altset.  The exception was
the sync EP without the implicit feedback which has usually the
secondary EP of the same altset.  This works fine for most devices,
but it turned out that some unusual devices like Pinoeer's ones have
both playback and capture endpoints in the same iface/altsetting and
use both for the implicit feedback mode.  For handling such a case, we
need to extend the endpoint management to take the shared interface
into account.

This patch does that: it adds a new object snd_usb_iface_ref for
managing the reference counts of the each USB interface that is used
by each endpoint.  The interface setup is performed only once for the
(sharing) endpoints, and the doubly initialization is avoided.

Along with this, the resource release of endpoints and interface
refcounts are put into a single function, snd_usb_endpoint_free_all()
instead of looping in the caller side.

Takashi Iwai 5d15f1eb45 ALSA: usb-audio: Choose audioformat of a counter-part substream
The implicit feedback mode needs to handle two endpoints and the
choice of the audioformat object for the sync EP is important since
this determines the compatibility of the hw_params.  The current code
uses the same audioformat object if both the main EP and the sync EP
point to the same iface/altsetting.  This was done in consideration of
the non-implicit-fb sync EP handling, and it doesn't match well with
the cases where actually to endpoints are defined in the sameiface /
altsetting like a few Pioneer devices.

Modify snd_usb_find_implicit_fb_sync_format() to pick up the
audioformat that is assigned in the counter-part substreams primarily,
so that the actual capture stream can be opened properly.  We keep the
same audioformat object only as a fallback in case nothing found,
though.

Takashi Iwai b2345a8a43 ALSA: usb-audio: Fix the missing endpoints creations for quirks
The recent change in the endpoint management moved the endpoint object
creation from the stream open time to the parser of the audio
descriptor.  It works fine for the standard audio, but it overlooked
the other places that create audio streams via quirks
(QUIRK_AUDIO_FIXED_ENDPOINT) like the reported a few Pioneer devices;
those call snd_usb_add_audio_stream() manually, hence they miss the
endpoints, eventually resulting in the error at opening streams.
Moreover, now the sync EP setup was moved to the explicit call of
snd_usb_audioformat_set_sync_ep(), and this needs to be added for
those places, too.

This patch addresses those regressions for quirks.  It adds a local
helper function add_audio_stream_from_fixed_fmt(), which does the all
needed tasks, and replaces the calls of snd_usb_add_audio_stream()
with this new function.

Takashi Iwai 4bfd6247fa ALSA: hda/via: Fix runtime PM for Clevo W35xSS
Clevo W35xSS_370SS with VIA codec has had the runtime PM problem that
looses the power state of some nodes after the runtime resume.  This
was worked around by disabling the default runtime PM via a denylist
entry.  Since 5.10.x made the runtime PM applied (casually) even
though it's disabled in the denylist, this problem was revisited.  The
result was that disabling power_save_node feature suffices for the
runtime PM problem.

This patch implements the disablement of power_save_node feature in
VIA codec for the device.  It also drops the former denylist entry,
too, as the runtime PM should work in the codec side properly now.

Without this quirk it is neither possible to capture audio from nor to

ASoC: amd: Replacing MSI with Legacy IRQ model
When we try to play and capture simultaneously we see that
interrupts are genrated but our handler is not being acknowledged,
After investigating further more in detail on this issue we found
that IRQ delivery via MSI from the ACP IP is unreliable and so sometimes
interrupt generated will not be acknowledged so MSI model shouldn't be used
and using legacy IRQs will resolve interrupt handling issue.

This patch replaces MSI interrupt handling with legacy IRQ model.

Issue can be reproduced easily by running below python script:

import subprocess
import time
import threading

def do2():
  cmd = 'aplay -f dat -D hw:2,1 /dev/zero -d 1'
    subprocess.call(cmd, stdin=subprocess.PIPE,
			stderr=subprocess.PIPE, shell=True)
    print('Play Done')

def run():
	for i in range(1000):
		do2()

def do(i):
    cmd = 'arecord -f dat -D hw:2,2 /dev/null -d 1'
    subprocess.call(cmd, stdout=subprocess.PIPE,
			stderr=subprocess.PIPE, shell=True)
    print(datetime.datetime.now(), i)

t = threading.Thread(target=run)
t.start()
for i in range(1000):
	do(i)

t.join()

After applying this patch issue is resolved.

Linus Torvalds 14e3e989f6 proc mountinfo: make splice available again
Since commit 36e2c7421f ("fs: don't allow splice read/write without
explicit ops") we've required that file operation structures explicitly
enable splice support, rather than falling back to the default handlers.

Most /proc files use the indirect 'struct proc_ops' to describe their
file operations, and were fixed up to support splice earlier in commits
40be821d627c..b24c30c67863, but the mountinfo files interact with the
VFS directly using their own 'struct file_operations' and got missed as
a result.

This adds the necessary support for splice to work for /proc/*/mountinfo
and friends.

the final '\n' to the seq_printf() above it.

Rob Herring 275e88b06a PCI: tegra: Fix host link initialization
Commit b9ac0f9dc8 ("PCI: dwc: Move dw_pcie_setup_rc() to DWC common
code") broke enumeration of downstream devices on Tegra:

In non-working case (next-20201211):

  0001:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad2 (rev a1)
  0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)
  0005:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad0 (rev a1)

In working case (v5.10-rc7):

  0001:00:00.0 PCI bridge: Molex Incorporated Device 1ad2 (rev a1)
  0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)
  0005:00:00.0 PCI bridge: Molex Incorporated Device 1ad0 (rev a1)
  0005:01:00.0 PCI bridge: PLX Technology, Inc. Device 3380 (rev ab)
  0005:02:02.0 PCI bridge: PLX Technology, Inc. Device 3380 (rev ab)
  0005:03:00.0 USB controller: PLX Technology, Inc. Device 3380 (rev ab)

The problem seems to be dw_pcie_setup_rc() is now called twice before and
after the link up handling. The fix is to move Tegra's link up handling to
.start_link() function like other DWC drivers. Tegra is a bit more
complicated than others as it re-inits the whole DWC controller to retry
the link. With this, the initialization ordering is restored to match the
prior sequence.

Linus Torvalds 61d791365b drm/amd/display: avoid uninitialized variable warning
clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.

This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.

So just initialize 'val' to zero to avoid the issue.

Linus Torvalds 5814bc2d4c perf tools changes for v5.11, 2nd batch:
- Refactor 'perf stat' per CPU/socket/die/thread aggregation fixing use
   cases in ARM machines.
 
 - Fix memory leak when synthesizing SDT probes in 'perf probe'.
 
 - Update kernel header copies related to KVM, epol_pwait. msr-index and
   powerpc and s390 syscall tables.
 
 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
 
 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.

Michael Ellerman 11cc92eb74 genirq: Fix export of irq_to_desc() for powerpc KVM
Commit 64a1b95bb9 ("genirq: Restrict export of irq_to_desc()") removed
the export of irq_to_desc() unless powerpc KVM is being built, because
there is still a use of irq_to_desc() in modular code there.

However it used:

  #ifdef CONFIG_KVM_BOOK3S_64_HV

Which doesn't work when that symbol is =m, leading to a build failure:

  ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined!

Fix it by checking for the definedness of the correct symbol which is
CONFIG_KVM_BOOK3S_64_HV_MODULE.

Fixes: 64a1b95bb9 ("genirq: Restrict export of irq_to_desc()")
