i.MX95 has a DDR pmu. This will add a compatible for it.

The user can set event and counter in cmdline and the driver need to parse
it using 'config' attr value. This will add macro definitions to avoid
hard-code in driver.

* [PATCH v8 3/8] perf: imx_perf: let the driver manage the counter usage rather the user

In current design, the user of perf app needs to input counter ID to count
events. However, this is not user-friendly since the user needs to lookup
the map table to find the counter. Instead of letting the user to input
the counter, let this driver to manage the counters in this patch.
This will be implemented by:
1. allocate counter 0 for cycle event.
2. find unused counter from 1-10 for reference events.
3. allocate specific counter for counter-specific events.
In this patch, counter attribute is removed too. To mark counter-specific
events, counter ID will be encoded into perf_pmu_events_attr.id.

* [PATCH v8 3/8] perf: imx_perf: let the driver manage the counter usage rather the user

In current design, the user of perf app needs to input counter ID to count
events. However, this is not user-friendly since the user needs to lookup
the map table to find the counter. Instead of letting the user to input
the counter, let this driver to manage the counters in this patch.
This will be implemented by:
1. allocate counter 0 for cycle event.
2. find unused counter from 1-10 for reference events.
3. allocate specific counter for counter-specific events.
In this patch, counter attribute is removed too. To mark counter-specific
events, counter ID will be encoded into perf_pmu_events_attr.id.

This driver is initinally used to support imx93 Soc and now it's time to
add support for imx95 Soc. However, some macro definitions and events are
different on these two Socs. For preparing imx95 supports, this will
refactor driver for imx93.

In current driver, the counter will start firstly and then be configured.
This sequence is not correct for AXI filter events since the correct
AXI_MASK and AXI_ID are not set yet. Then the results may be inaccurate.

i.MX95 has a DDR PMU which is almostly same as i.MX93, it now supports
read beat and write beat filter capabilities. This will add support for
i.MX95 and enhance the driver to support specific filter handling for it.
Usage:
For read beat:
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt2,axi_mask=ID_MASK,axi_id=ID/
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt1,axi_mask=ID_MASK,axi_id=ID/
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt0,axi_mask=ID_MASK,axi_id=ID/
eg: For edma2: perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt0,axi_mask=0x00f,axi_id=0x00c/
For write beat:
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_wr_beat_filt,axi_mask=ID_MASK,axi_id=ID/
eg: For edma2: perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_wr_beat_filt,axi_mask=0x00f,axi_id=0x00c/

Changes in v2:
- put soc spefific axi filter events to drvdata according
to franks suggestions.
- adjust pmcfg axi_id and axi_mask config
Changes in v3:
- no changes
Changes in v4:
- only contain imx95 parts
Changes in v5:
- improve imx95_ddr_perf_monitor_config()
- use write_relaxed to pair read_relaxed
Changes in v6:
- no changes
Changes in v7:
- no changes
Changes in v8:
- add definition IMX95_DDR_PMU_EVENT_ATTR

I think we still have to support the old interface so that we don't break
those existing users (even if the driver just ignores whatever counter ID
is provided in a backwards-compatible way).

Sadly, this is a user-visible change so I think it will break old tools,
won't it?

For imx ddr pmu, most of the people will use metrics rather event itself,
and we have speficy the format of event parameters in metrics table.
The parameters is also updated in this patchset.
And to easy use for user, the counter should be hidden (transparent) to
user after I had talk with Frank. Then, the user need't to look up the event
table to find which counter to use.
So this patchset will basically not break the usage of perf tools and will
improve practicality.

Sorry, but I don't agree. The original commit adding this driver
(55691f99d417) gives the following examples in the commit message:
For example:
perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_trans_filt,counter=2,axi_mask=ID_MASK,axi_id=ID/
perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_wr_trans_filt,counter=3,axi_mask=ID_MASK,axi_id=ID/
perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt,counter=4,axi_mask=ID_MASK,axi_id=ID/
I don't think these will work any more if we apply this patch.

For example:
perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_trans_filt,counter=2,axi_mask=ID_MASK,axi_id=ID/
perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_wr_trans_filt,counter=3,axi_mask=ID_MASK,axi_id=ID/
perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt,counter=4,axi_mask=ID_MASK,axi_id=ID/
I don't think these will work any more if we apply this patch.
Will

Yang:
keep compatible is important. Please try well's suggestion
"if the driver just ignores whatever counter ID is provided in a
backwards-compatible way)."
If you have further question, you can ping directly. Please avoid
use outlook to reply community email. It always append annoised "EXT".
