Jason Bonnell 463126770a Update build docker container workflow, opensuse dockerfiles (#1883)
## Motivation

<!-- Explain the purpose of this PR and the goals it aims to achieve. -->

- __Reduced Code Duplication__: Version parsing logic moved from individual Dockerfiles to the central build script
- __Improved Edge Case Handling__: Better handling of ROCm versions with and without patch numbers (e.g., `6.2` vs `6.2.0`)
- __Easier Maintenance__: Future version-related changes only need to be made in one place
- __Cleaner Dockerfiles__: Simplified Dockerfiles focus on package installation rather than complex shell logic
- __Updated Platform Support__: Refreshed container matrix to reflect current platform/ROCm version combinations
- __Fix OpenSUSE Docker Generation__: OpenSUSE container generation fails due to a change to the `binutils-gold` package
- __Error Handling__: Fix bug where errors in docker image build were being masked, allowing workflow to pass anyway.


## Technical Details

<!-- Explain the changes along with any relevant GitHub links. -->
- Updated `Dockerfile.opensuse` and `Dockerfile.opensuse.ci` docker files to remove `binutils-gold`
  - Not needed since we build `binutils` with systems anyways
- Updated `rocprofiler-systems-containers.yml` to remove `pushd/popd` commands and just run the shell scripts
  - There was a silent failure observed here, which I verified in this PR before adding the fix for openSUSE
- Refactor ROCm version parsing. Move this logic to the `build-docker.sh` script to reduce duplication.
  - Fix bug that caused ROCm 7.0 to fail installation. The trailing `.0` was being trimmed.
- Fixed inconsistencies in `containers.yml` that lead to invalid ROCm-OS_VERSION combinations.
- Formatting fixes 
  - Removed trailing whitespace
  - Fix docker build warnings. Use an `=` rather than ` ` when assigning an environment variable.

marantic-amd 3b11e01716 Perfetto traces from cached data (#1704)
## Motivation

The idea is to unify the way and place where we store our traces. Current implementation uses `trace_cache` for rocpd traces, but perfetto is in lined inside of each module. This change allows us to have a single point in code where we will collect data, process it and store it in the desired format. This means that we can declutter the code further and have single point of responsibility and single point of failure.

## Technical Details

New `processor` (perfetto_post_processing.cpp) is added to the `trace_cache` which purpose is to use the cached data to populate perfetto tracks. Cache manager is responsible for keeping the instance of this processor and for its lifetime.

Kian Cossettini b506c75f28 [rocprof-sys] Fix roctx wall clock tree, change timemory push/pop to use proper category, and add roctx as valid domain choice (#2062)
When doing this ticket, I also noticed the program would SEGFAULT when ROCPROFSYS_ROCM_DOMAINS=roctx even though the docs tell us we can do this. Went ahead and fixed that.

Also noticed that timemory push/pop in rocprofiler-sdk.cpp was always using category::rocm_marker_api instead of CategoryT. Fixed that as well.

Milan Radosavljevic ee7305e795 [rocprof-sys] Add test cleanup fixtures for binary-rewrite and runtime-instrument tests (#2012)
- Added `binary-rewrite-cleanup` and `runtime-instrument-cleanup` tests that remove instrumented binaries and output directories using `cmake -E rm -rf`
- Implemented CMake test fixtures (`FIXTURES_SETUP` and `FIXTURES_CLEANUP`) to establish proper test ordering:
  - `binary-rewrite` sets up the `binary-rewrite-fixture`
  - `binary-rewrite-run` and validation tests require this fixture
  - `binary-rewrite-cleanup` performs cleanup for this fixture
  - Same pattern applied for `runtime-instrument`
- Extended `ROCPROFILER_SYSTEMS_ADD_PYTHON_TEST` to accept `FIXTURES_REQUIRED` parameter
- Updated validation tests to require appropriate cleanup fixtures based on test name pattern matching
- Added fixture requirements to Python code-coverage tests

marantic-amd daf8596ce9 [rocprof-sys] Process all information regarding agents and store them as extdata in rocpd database (#1880)
## Motivation

Resolved: SWDEV-566226

The current implementation of agents inside of rocprof-systems keeps just the minimal necessary set of information required for populating the `info_agent` table inside of rocpd database. There is a sufficient amount of data that is being left out from database, so this change should fix that and store the additional agent information as an `extdata` row inside of `info_agent` table.

## Technical Details

This PR introduces additional filed inside of `agent` structure inside which is representing the JSON formatted string of all the additional information we can acquire about particular agent. This data is processed and added during the initial fetching of agents, and afterwards pushed inside of the database.

anujshuk-amd 85b5c03f36 [rocprof-sys] Fix test build failure on RHEL 10 (#1955)
## Motivation

To solve: SWDEV-566076 
FFmpeg versions >= 58.134 no longer expose read_seek and read_seek2 function pointers in AVInputFormat,
requiring alternative seek detection methods. This pull request updates the `VideoDemuxer` class to improve compatibility with newer versions of FFmpeg. The main change is how the code determines whether the input file is seekable, addressing differences in FFmpeg API versions.


## Technical Details

In `video_demuxer.h`, added a conditional check for `USE_AVCODEC_GREATER_THAN_58_134` to set `is_seekable_` to `true` for newer FFmpeg versions, since `read_seek` and `read_seek2` are no longer exposed in `AVFormatContext`. For older versions, the previous method of checking these fields remains in place. The conditional compilation
now assumes seek capability is available for newer FFmpeg versions.

Sajina PK d77b245730 [Rocprofiler-systems] : Refactor papi enumeration to fix a hang on Intel systems (#1672)
* Refactor papi enumeration to fix a hang on Intel systems

- Add an exclude argument to available_events_info() for
  perf_event_uncore causing hang like case on Intel systems with large
number of uncore events.
- Enumerate papi available events only when papi events are specified by
  users inside early initialization logic
- Move papi available event query for ROCPROFSYS_SAMPLING_OVERFLOW_EVENT
  config setting to the avail component, to move the heavy logic outside
initialization.
- Make category option for rocprof-sys-avail -H -c case insensitive
- Provide new option to query available overflow events that can be
  specified for ROCPROFSYS_SAMPLING_OVERFLOW_EVENT using new command
option rocprof-sys-avail -H -c overflow
