### Feature Support and Performance
The AMD Open Source Driver for Vulkan is designed to support the following features:
* Vulkan 1.1
* Vulkan 1.2
* More than 30 extensions
* [Radeon™ GPUProfiler](https://github.com/GPUOpen-Tools/Radeon-GPUProfiler) tracing

### Known Issues
* CTS may hang in VK.synchronization.internally_synchronized_objects.pipeline_cache_compute with Linux kernel versions lower than 4.13
* The driver can only work with firmware of ME feature version >= 25 (you can check the version with command "sudo cat /sys/kernel/debug/dri/0/amdgpu_firmware_info"). If you are using upstream stack with GPUs of SI or CI family, you may need to upgrade the kernel to 4.19 or later version and firmware (under /lib/firmware/amdgpu/) to the right version from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu, and then update ramfs (sudo mkinitramfs -o /boot/initrd.img-\`uname -r\` \`uname -r\`)
* Timeline semaphore is not fully supported in Linux kernel until version 5.5. You can install [Vulkan timeline semaphore layer](https://github.com/KhronosGroup/Vulkan-ExtensionLayer) to enable the extension if you are using earlier version of Linux kernel
