Commit 54b5091606c18 ("perf stat: Implement --metric-only mode")
added function 'valid_only_metric()' which drops "Hz" or "hz",
if it is part of "ScaleUnit". This patch enable it since hv_24x7

[PATCH v4 6/8] perf/tools: Enhance JSON/metric infrastructure to handle "?"
Patch enhances current metric infrastructure to handle "?" in the metric
expression. The "?" can be use for parameters whose value not known while
creating metric events and which can be replace later at runtime to
the proper value. It also add flexibility to create multiple events out
of single metric event added in json file.
Patch adds function 'arch_get_runtimeparam' which is a arch specific
function, returns the count of metric events need to be created.
By default it return 1.
One loop is added in function 'metricgroup__add_metric', which create
multiple events at run time depend on return value of
'arch_get_runtimeparam' and merge that event in 'group_list'.
This infrastructure needed for hv_24x7 socket/chip level events.
"hv_24x7" chip level events needs specific chip-id to which the
data is requested. Function 'arch_get_runtimeparam' implemented
in header.c which extract number of sockets from sysfs file
"sockets" under "/sys/devices/hv_24x7/interface/".

[PATCH v4 2/8] powerpc/hv-24x7: Add rtas call in hv-24x7 driver to get processor details
For hv_24x7 socket/chip level events, specific chip-id to which
the data requested should be added as part of pmu events.
But number of chips/socket in the system details are not exposed.
Patch implements read_sys_info_pseries() to get system
parameter values like number of sockets and chips per socket.
Rtas_call with token "PROCESSOR_MODULE_INFO"
is used to get these values.
Sub-sequent patch exports these values via sysfs.
Patch also make these parameters default to 1.

[PATCH v4 1/8] powerpc/perf/hv-24x7: Fix inconsistent output values incase multiple hv-24x7 events run
Commit 2b206ee6b0df ("powerpc/perf/hv-24x7: Display change in counter
values")' added to print _change_ in the counter value rather then raw
value for 24x7 counters. Incase of transactions, the event count
is set to 0 at the beginning of the transaction. It also sets
the event's prev_count to the raw value at the time of initialization.
Because of setting event count to 0, we are seeing some weird behaviour,
whenever we run multiple 24x7 events at a time.
For example:
command#: ./perf stat -e "{hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=0/,
hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=1/}"

hv_24x7/PM_MCS01_128B_RD_DISP_PORT01,chip=0/
Getting these large values in case we do -I.
As we are setting event_count to 0, for interval case, overall event_count is
not
coming in incremental order. As we may can get new delta lesser then previous
count.
Because of which when we print intervals, we are getting negative value which
create
these large values.
This patch removes part where we set event_count to 0 in function
'h_24x7_event_read'. There won't be much impact as we do set
event->hw.prev_count
to the raw value at the time of initialization to print change value.

[PATCH v4 0/8] powerpc/perf: Add json file metric support for the hv_24x7 socket/chip level events
First patch of the patchset fix inconsistent results we are getting when we run multiple 24x7 events. Patchset adds json file metric support for the hv_24x7 socket/chip level events. "hv_24x7" pmu interface events needs system dependent parameter like socket/chip/core. For example, hv_24x7 chip level events needs specific chip-id to which the data is requested should be added as part of pmu events. So to enable JSON file support to "hv_24x7" interface, patchset expose total number of sockets and chips per-socket details in sysfs files (sockets, chips) under "/sys/devices/hv_24x7/interface/". To get sockets and number of chips per sockets, patchset adds a rtas call with token "PROCESSOR_MODULE_INFO" to get these details. Patchset also handles partition migration case to re-init these system depended parameters by adding proper calls in post_mobility_fixup() (mobility.c). Patch 6 & 8 of the patchset handles perf tool plumbing needed to replace the "?" character in the metric expression to proper value and hv_24x7 json metric file for different Socket/chip resources. Patch set also enable Hz/hz prinitg for --metric-only option to print metric data for bus frequency. Applied and tested all these patches cleanly on top of jiri's flex changes with the changes done by Kan Liang for "Support metric group constraint" patchset and made required changes. Changelog: v3 -> v4 - Made changes suggested by jiri. - Apply these patch on top of Kan liang changes. v2 -> v3 - Remove setting event_count to 0 part in function 'h_24x7_event_read' with comment rather then adding 0 to event_count value. Suggested by: Sukadev Bhattiprolu - Apply tool side changes require to replace "?" on Jiri's flex patch series and made all require changes to make it compatible with added flex change. v1 -> v2 - Rename hv-24x7 metric json file as nest_metrics.json Kajol Jain (8): powerpc/perf/hv-24x7: Fix inconsistent output values incase multiple hv-24x7 events run powerpc/hv-24x7: Add rtas call in hv-24x7 driver to get processor details powerpc/hv-24x7: Add sysfs files inside hv-24x7 device to show processor details Documentation/ABI: Add ABI documentation for chips and sockets powerpc/hv-24x7: Update post_mobility_fixup() to handle migration perf/tools: Enhance JSON/metric infrastructure to handle "?" tools/perf: Enable Hz/hz prinitg for --metric-only option perf/tools/pmu-events/powerpc: Add hv_24x7 socket/chip level metric events .../sysfs-bus-event_source-devices-hv_24x7| 14 ++ arch/powerpc/perf/hv-24x7.c | 104 +-- arch/powerpc/platforms/pseries/mobility.c | 12 ++ arch/powerpc/platforms/pseries/pseries.h | 3 + tools/perf/arch/powerpc/util/header.c | 22 .../arch/powerpc/power9/nest_metrics.json | 19 +++ tools/perf/util/expr.h| 1 + tools/perf/util/expr.l| 19 ++- tools/perf/util/metricgroup.c | 124 ++ tools/perf/util/metricgroup.h | 1 + tools/perf/util/stat-display.c| 2 - tools/perf/util/stat-shadow.c | 8 ++ 12 files changed, 290 insertions(+), 39 deletions(-) create mode 100644 tools/perf/pmu-events/arch/powerpc/power9/nest_metrics.json -- 2.18.1
[PATCH v5 7/7] ASoC: fsl_easrc: Add EASRC ASoC CPU DAI drivers
EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module
found on i.MX8MN. It is different with old ASRC module.
The primary features for the EASRC are as follows:
- 4 Contexts - groups of channels with an independent time base
- Fully independent and concurrent context control
- Simultaneous processing of up to 32 audio channels
- Programmable filter charachteristics for each context
- 32, 24, 20, and 16-bit fixed point audio sample support
- 32-bit floating point audio sample support
- 8kHz to 384kHz sample rate
- 1/16 to 8x sample rate conversion ratio

In order to support new EASRC and simplify the code structure,
We decide to share the common structure between them. This bring
a problem that EASRC accept format directly from devicetree, but
ASRC accept width from devicetree.
In order to align with new ESARC, we add new property fsl,asrc-format.
The fsl,asrc-format can replace the fsl,asrc-width, then driver
can accept format from devicetree, don't need to convert it to
format through width.

[PATCH v5 5/7] ASoC: fsl_asrc: Move common definition to fsl_asrc_common
There is a new ASRC included in i.MX serial platform, there
are some common definition can be shared with each other.
So move the common definition to a separate header file.
And add fsl_asrc_pair_priv and fsl_asrc_priv for
the variable specific for the module, which can be used
internally.

Thanks for your good suggestion.
I will re-code based on your suggestion, if [2/2] turns out acceptable.

[PATCH v3] ima: add a new CONFIG for loading arch-specific policies
From: Nayna Jain Every time a new architecture defines the IMA architecture specific functions - arch_ima_get_secureboot() and arch_ima_get_policy(), the IMA include file needs to be updated. To avoid this "noise", this patch defines a new IMA Kconfig IMA_SECURE_AND_OR_TRUSTED_BOOT option, allowing the different architectures to select it. Suggested-by: Linus Torvalds Signed-off-by: Nayna Jain Acked-by: Ard Biesheuvel Cc: Ard Biesheuvel Cc: Philipp Rudo Cc: Michael Ellerman --- v3: * Removes CONFIG_IMA dependency. Thanks Ard. * Updated the patch with improvements suggested by Michael. It now uses "imply" instead of "select". Thanks Michael. * Replaced the CONFIG_IMA in x86 and s390 with new config, else it was resulting in redefinition when the IMA_SECURE_AND_OR_TRUSTED_BOOT is not enabled. Thanks to Mimi for identifying the problem. * Removed "#ifdef EFI" check in the arch/x86/Makefile for compiling ima_arch.c file. * Ard, Thanks for your Acked-by. I have changed the arch/x86/Makefile in this version. Can you please review again and confirm ? * Rudo, Thanks for your review. I have changed arch/s390/Makefile as well.

This is the powerpc-add-support-for-folded-p4d-page-tables.patch on top of
current powerpc/next. The powerpc-32-drop-get_pteptr.patch is already there
and I've folded powerpc-add-support-for-folded-p4d-page-tables-fix.patch
into this one.
