Thierry Reding <treding@nvidia.com>:
From: Thierry Reding <treding@nvidia.com>
This small series addresses a minor issue with how IOMMU support is
wired up on various Tegra generations. Currently the virtual "card"
device is used to allocate DMA memory for, but since that device does
not actually exist, the path to memory cannot be correctly described.
To address this, this series moves to using the ADMAIF as the DMA device
for audio. This is a real device that can have a proper DMA mask set and
with which a stream ID can be associated with in the SMMU. The memory
accesses technically originate from the ADMA controller (that the ADMAIF
uses), but DMA channel are dynamically allocated at runtime while DMA
memory is allocated at driver load time, drivers won't have access to
the ADMA device yet.
Further patches will be required to correct this issue on Tegra186 and
Tegra210, but I wanted to get feedback on this approach first.
Changes in v2:
- add backwards-compatibility fallback

ASoC: tegra: Use ADMAIF component for DMA allocations
DMA memory is currently allocated for the soundcard device, which is a
virtual device added for the sole purpose of "stitching" together the
audio device. It is not a real device and therefore doesn't have a DMA
mask or a description of the path to and from memory of accesses.
Memory accesses really originate from the ADMA controller that provides
the DMA channels used by the PCM component. However, since the DMA
memory is allocated up-front and the DMA channels aren't known at that
point, there is no way of knowing the DMA channel provider at allocation
time.
The next best physical device in the memory path is the ADMAIF. Use it
as the device to allocate DMA memory to. iommus and interconnects device
tree properties can thus be added to the ADMAIF device tree node to
describe the memory access path for audio.

mm/rmap: fix old bug: munlocking THP missed other mlocks
The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.
It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped. Refine the tests.
There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.
(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)

mm/rmap: fix comments left over from recent changes
Parallel developments in mm/rmap.c have left behind some out-of-date
comments: try_to_migrate_one() also accepts TTU_SYNC (already commented
in try_to_migrate() itself), and try_to_migrate() returns nothing at
all.
TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it
in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so
delete the "recently referenced" comment from try_to_unmap_one() (once

present for a hole in the physical memory and if such hole corresponds

rtc: pcf2127: handle timestamp interrupts
commit
03623b4b041c ("rtc: pcf2127: add tamper detection support")
added support for timestamp interrupts. However they are not being
handled in the irq handler. If a timestamp interrupt occurs it
results in kernel disabling the interrupt and displaying the call
trace:
[ 121.145580] irq 78: nobody cared (try booting with the "irqpoll" option)
...
[ 121.238087] [<
00000000c4d69393>] irq_default_primary_handler threaded [<
000000000a90d25b>] pcf2127_rtc_irq [rtc_pcf2127]
[ 121.248971] Disabling IRQ #78
Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp
before clearing TSF1 and TSF2 flags so that it can't be overwritten.
Set a flag to mark if the timestamp is valid and only report to sysfs
if the flag is set. To mimic the hardware behavior, don’t save
another timestamp until the first one has been read by the userspace.
However, if the alarm irq is not configured, keep the old way of
handling timestamp interrupt in the timestamp0 sysfs calls.

perf tools: Fix pattern matching for same substring in different PMU type
Some different PMU types may have the same substring. For example, on
Icelake server we have PMU types "uncore_imc" and
"uncore_imc_free_running". Both PMU types have the substring
"uncore_imc". But the parser wrongly thinks they are the same PMU type.
We enable an imc event,
perf stat -e uncore_imc/event=0xe3/ -a -- sleep 1
Perf actually expands the event to:
uncore_imc_0/event=0xe3/
uncore_imc_1/event=0xe3/
uncore_imc_2/event=0xe3/
uncore_imc_3/event=0xe3/
uncore_imc_4/event=0xe3/
uncore_imc_5/event=0xe3/
uncore_imc_6/event=0xe3/
uncore_imc_7/event=0xe3/
uncore_imc_free_running_0/event=0xe3/
uncore_imc_free_running_1/event=0xe3/
uncore_imc_free_running_3/event=0xe3/
uncore_imc_free_running_4/event=0xe3/
That's because the "uncore_imc_free_running" matches the
pattern "uncore_imc*".
Now we check that the last characters of PMU name is '_<digit>'.
For example, for pattern "uncore_imc*", "uncore_imc_0" is parsed ok, but
"uncore_imc_free_running_0" fails.

perf record: Add a dummy event on hybrid systems to collect metadata records
Some symbols may not be resolved if a user only monitors one type of
PMU.
$ sudo perf record -e cpu_atom/branch-instructions/ ./big_small_workload
$ sudo perf report –stdio
# Overhead Command Shared Object Symbol
# ........ ......... ................. .....................

10.61% perf-exec [unknown] [.] 0x0000000000401cfc
To parse symbols the metadata records, e.g., PERF_RECORD_COMM, which are
generated by the kernel, are required.
To decide whether to generate the metadata records, the kernel relies on
the event_filter_match() to filter the unrelated events.
On a hybrid system, event_filter_match() further checks the CPU mask of
the current enabled PMU. If an event is collected on the CPU which
doesn't have an enabled PMU, it's treated as an unrelated event.
The "big_small_workload" is created in a big core, but runs on a small
core. The metadata records are filtered, because the user only monitors
the PMU of the small core. The big core PMU is not enabled.
For a hybrid system, a dummy event is required to generate the complete
side-band events.

perf stat: Add Topdown metrics L2 events as default events
The Topdown Microarchitecture Analysis (TMA) Method is a structured
analysis methodology to identify critical performance bottlenecks in
out-of-order processors.
The Topdown metrics L1 event was added as default in
42641d6f4d15e6db
("perf stat: Add Topdown metrics events as default events")
From the Sapphire Rapids server and later platforms, the same dedicated
"metrics" register is extended to support both L1 and L2 events.
Add both L1 and L2 Topdown metrics events as default to enrich the
default measuring information if the new measurement register is
available.
On legacy systems there is no change to avoid extra multiplexing.
The topdown_level indicates the max metrics level for the top-down
statistics. Set it to 2 to display all L1 and L2 Topdown metrics events.

libperf: Move 'leader' from tools/perf to perf_evsel::leader
Move evsel::leader to perf_evsel::leader, so we can move the group
interface to libperf.
Also add several evsel helpers to ease up the transition:
struct evsel *evsel__leader(struct evsel *evsel);
- get leader evsel
bool evsel__has_leader(struct evsel *evsel, struct evsel *leader);
- true if evsel has leader as leader
bool evsel__is_leader(struct evsel *evsel);
- true if evsel is itw own leader
void evsel__set_leader(struct evsel *evsel, struct evsel *leader);
- set leader for evsel
Committer notes:
Fix this when building with 'make BUILD_BPF_SKEL=1'
tools/perf/util/bpf_counter.c
- if (evsel->leader->core.nr_members > 1) {
+ if (evsel->core.leader->nr_members > 1) {

libperf: Move 'idx' from tools/perf to perf_evsel::idx
Move evsel::idx to perf_evsel::idx, so we can move the group interface
to libperf.
Committer notes:
Fixup evsel->idx usage in tools/perf/util/bpf_counter_cgroup.c, that
appeared in my tree in my local tree.
Also fixed up these:
$ find tools/perf/ -name "*.[ch]" | xargs grep 'evsel->idx'
tools/perf/ui/gtk/annotate.c: evsel->idx + i);
tools/perf/ui/gtk/annotate.c: evsel->idx);
$
That running 'make -C tools/perf build-test' caught.

"In this round, we've improved the compression support especially for
Android such as allowing compression for mmap files, replacing the
immutable bit with internal bit to prohibits data writes explicitly,
and adding a mount option, "compress_cache", to improve random reads.
And, we added "readonly" feature to compact the partition w/
compression enabled, which will be useful for Android RO partitions.
Enhancements:
- support compression for mmap file
- use an f2fs flag instead of IMMUTABLE bit for compression
- support RO feature w/ extent_cache
- fully support swapfile with file pinning
- improve atgc tunability
- add nocompress extensions to unselect files for compression
Bug fixes:
- fix false alaram on iget failure during GC
- fix race condition on global pointers when there are multiple f2fs
instances
- add MODULE_SOFTDEP for initramfs
As usual, we've also cleaned up some places for better code
readability (e.g., sysfs/feature, debugging messages, slab cache
name, and docs)"
