> **Note:**
* If the build runs into errors like "collect2: fatal error: ld terminated with signal 9 [Killed]" due to out of memory, you could try with reducing the number of threads in "make" command.
* Debug build can be done by using -DCMAKE_BUILD_TYPE=Debug
* Debug build can be done by using -DCMAKE_BUILD_TYPE=Debug.
* To enable Wayland support, you need to build the driver by using -DBUILD_WAYLAND_SUPPORT=ON and install the Wayland [WSA libarary](https://github.com/GPUOpen-Drivers/wsa).

| `ShaderCacheMode` | 0: disable cache<br/>1: runtime cache<br/>2: cache to disk | Runtime cache is the default mode. |
| `IFH` | 0: default<br/>1: drop all submits<br/> | Infinitely Fast Hardware. Submit calls are dropped before being sent to hardware. Useful for measuring CPU-limited performance. |
| `EnableVmAlwaysValid` | 0: disable<br/>1: enable<br/> | 1 is the default setting which enables the VM-always-valid feature for kernel 4.16 and above. The feature can reduce command buffer submission overhead related to virtual memory management. |
| `EnableVmAlwaysValid` | 0: disable<br/>1: default<br/>2: force enable<br/> | 1 is the default setting which enables the VM-always-valid feature for kernel 4.16 and above. The feature can reduce command buffer submission overhead related to virtual memory management. |
| `IdleAfterSubmitGpuMask` | Bitmask of GPUs (i.e., bit 0 is GPU0, etc.) | Forces the CPU to immediately wait for each GPU submission to complete on the specified set of GPUs. |
*All* available settings can be determined by examining the .cfg source files that define them.
