+# DCVS Frequency Scaling Validation Test
+
+This test validates the DCVS support and runtime status on Qualcomm platforms with Yocto builds.
+
+## Overview
+
+The test script performs these functional checks:
+
+1. **Kernel Configuration**:
+   - Validates presence of `CONFIG_CPU_FREQ`, `CONFIG_CPU_FREQ_GOV_PERFORMANCE` and `CONFIG_CPU_FREQ_GOV_SCHEDUTIL*` entries in `/proc/config.gz`.
+
+2. **Runtime Verification**:
+   - Checks `/sys/devices/system/cpu/cpu0/cpufreq` before and after a load is applied.
+
+## How to Run
+
+```sh
+source init_env
+cd suites/Kernel/FunctionalArea/DCVS/Freq_Scaling
+./run.sh
+```
+
+## Prerequisites
+
+- `dmesg`, `grep`, `zgrep`, `lsmod` must be available
+- Root access may be required for complete validation
+
+## Result Format
+
+Test result will be saved in `Freq_Scaling.res` as:
+- `DCVS scaling appears functional. Test Passed` – if all validations pass
+- `DCVS did not scale as expected. Test Failed` – if any check fails

+# Scheduler CPU Affinity validation Test
+
+This test validates the Scheduler support and runtime status on Qualcomm platforms with Yocto builds.
+
+## Overview
+
+The test script performs these functional checks:
+
+1. **Kernel Configuration**:
+   - Validates presence of `CONFIG_SCHED_DEBUG`, `CONFIG_CGROUP_SCHED` and `CONFIG_SMP*` entries in `/proc/config.gz`.
+
+2. **Runtime Verification**:
+   - Checks cpu affinity by creating a CPU-bound background task
+
+## How to Run
+
+```sh
+source init_env
+cd suites/Kernel/FunctionalArea/Scheduler/CPU_affinity
+./run.sh
+```
+
+## Prerequisites
+
+- `taskset`, `grep`, `zgrep`, `top`, `chrt` must be available
+- Root access may be required for complete validation
+
+## Result Format
+
+Test result will be saved in `CPU_affinity.res` as:
+- `Default scheduling policy detected. Test passed` – if all validations pass
+- `Unexpected scheduling policy. Test Failed` – if any check fails

+# IOMMU Validation Test
+
+This test validates the IOMMU (Input-Output Memory Management Unit) support and runtime status on Qualcomm platforms with Yocto builds.
+
+## Overview
+
+The test script performs these functional checks:
+
+1. **Kernel Configuration**:
+   - Validates presence of `CONFIG_IOMMU_SUPPORT` and `CONFIG_ARM_SMMU*` entries in `/proc/config.gz`.
+
+2. **Driver Loading**:
+   - Confirms SMMU/IOMMU-related drivers are loaded via `/proc/modules`.
+
+3. **Device Tree Nodes**:
+   - Verifies IOMMU/SMMU-related nodes in `/proc/device-tree`.
+
+4. **Runtime Verification**:
+   - Checks `dmesg` for any runtime IOMMU initialization or fault logs.
+
+## How to Run
+
+```sh
+source init_env
+cd suites/Kernel/FunctionalArea/IOMMU_Validation
+./run.sh
+```
+
+## Prerequisites
+
+- `dmesg`, `grep`, `zgrep`, `lsmod` must be available
+- Root access may be required for complete validation
+
+## Result Format
+
+Test result will be saved in `IOMMU.res` as:
+- `IOMMU PASS` – if all validations pass
+- `IOMMU FAIL` – if any check fails
