+# Media Driver Open Source Kernel
+
+## Step1: Building IGA (Intel Graphics Assembler)
+
+1. Download or clone IGC (Intel Graphics Compiler)
+
+   https://github.com/intel/intel-graphics-compiler.git
+
+2. Chdir into 'intel-graphics-compiler' (or any other workspace folder of choice)
+
+   It should read the following folder strucutre:
+
+   workspace
+      |- visa
+      |- IGC
+      |- inc
+      |- 3d
+      |- skuwa
+
+3. Chdir into IGA sub-component
+```
+   cd visa/iga
+```
+4. Create build directory
+```
+    mkdir build
+```
+5. Change into build directory
+```
+    cd build
+```
+6. Run cmake
+```
+   cmake ../
+```
+7. Run make to build IGA project
+```
+   make
+```
+8. Get the output executable "iga64" in IGAExe folder
+
+
+## Step2: Building the other post processing tools
+
+1. Download or clone Tool
+
+   https://github.com/intel/media-driver
+
+2. Chdir into "Tools/MediaDriverTools/GenKrnBin"
+
+3. Create build directory
+```
+   mkdir build
+```
+5. Change into build directory
+```
+   cd build
+```
+6. Run cmake
+```
+   cmake ../
+```
+7. Run make to build GenKrnBin project
+```
+   make
+```
+8. Get the output executable "GenKrnBin" in build folder
+
+9. Chdir into "Tools/MediaDriverTools/KernelBinToSource"
+
+10. Create build directory
+```
+    mkdir build
+```
+11. Change into build directory
+
+    cd build
+
+12. Run cmake
+```
+    cmake ../
+```
+13. Run make to build KernelBinToSource project
+```
+    make
+```
+14. Get the output executable "KernelBinToSource" in build folder
+
+15. Chdir into "Tools/MediaDriverTools/KrnToHex_IGA"
+
+16. Create build directory
+```
+    mkdir build
+```
+17. Change into build directory
+```
+    cd build
+```
+18. Run cmake
+```
+    cmake ../
+```
+19. Run make to build KrnToHex_IGA project
+```
+    make
+```
+20. Get the output executable "KrnToHex_IGA" in build folder
+
+
+## Step3: Building the kernel asm code to igvpkrn_g11_icllp.c and igvpkrn_g11_icllp.h
+
+1. Download or clone Driver source code
+
+   https://github.com/intel/media-driver
+
+2. Chdir into "./agnostic/gen11_icllp/vp/kernel"
+
+3. Create compile directory
+```
+   mkdir compile
+```
+4. Copy tool biniary (GenKrnBin, KernelBinToSource and KrnToHex_IGA) from step2 to compile folder
+
+3. Create IGA directory
+```
+   mkdir IGA
+```
+5. Copy tool biniary (iga64) from step1 to IGA folder
+
+6. Chdir into "./agnostic/gen11_icllp/vp/kernel"
+
+7. run build.py script to generate igvpkrn_g11_icllp.c and igvpkrn_g11_icllp.h
