===== AMD Graphics =====

AMD based GPUs are supported using the ''%%graphics/drm-kmod%%'' port or package.  Unlike the ''%%i915 %%''Intel graphics driver there are two separate modules available for AMD devices based on their generation.  The modules are named:

  * amdgpu
  * radeonkms

:!: The tables included are **not** an exhaustive list of supported hardware. Hardware is only listed if and when it has been explicitly tested/confirmed by developers and/or users. Graphics hardware missing from these tables may or may not work. If you have tested hardware that is not on the list, please [[#Reporting|report the results]].

**About GPU codenames vs. marketing names**

The entries below are misleading because they use the marketing names as the "key". This table needs to be rewritten using GPU codenames as the key.
</callout>

==== Hardware Support ====

You may wish to consult the [[Graphics/AMD-GPU-Matrix|AMD graphics support matrix view]] page.  The Xorg project also has a great resource on decoding AMD marketing names to engineering friendly names [[https://www.x.org/wiki/RadeonFeature/#index5h2|here]].

It is important to note that there is currently a conflict with both AMD drivers and the EFI frambuffer.  The current workaround, when booting via UEFI on these systems, is to disable the framebuffer via /boot/loader.conf:

''%%hw.syscons.disable=1%%''

This will have the side effect of there being no console output until either the amdgpu or radeonkms kernel driver is loaded.  Please see [[https://github.com/FreeBSDDesktop/DEPRECATED-freebsd-base-graphics/issues/170|this Github issue]] for more context.

One final note - there is a patch available [[https://github.com/FreeBSDDesktop/kms-drm/issues/33#issuecomment-422793245|here]] that will allow you to use Vulkan, %%OpenCL%%, Xwayland and %%OpenMW%% when using Wayland.

=== AMD GPU ===

AMD GPU is the kernel module that can be used to support **post-HD7000 or Tahiti GPUs**.  To enable graphics on these systems you would do the following:

  * Install the [[https://www.freshports.org/graphics/drm-kmod/|drm-kmod]] package ''%%$ sudo pkg install drm-kmod%%''

  * Take note of the post-install package message as it contains important information - specifically add this to your /etc/rc.conf or /etc/rc.conf.d/amd file: ''%%kld_list="/boot/modules/amdgpu.ko"%%''

  * Ensure that your UID is a member of the ''%%video%%'' group:
    * ''%%pw groupmod wheel -m <youruser>%%''

  * Restart your system; you should see the amdgpu.ko get loaded and a flash on your console as we switch over to the new display driver.

  * Start Xorg via your usual method (i.e. startx, GDM, etc.)

=== Radeon KMS ===

Radeon KMS is a distinct driver intended for older AMD based GPUs that are available in **pre-HD7000 or Tahiti GPUs**.  To enable graphics on systems with these GPUs you would do the following:

  * Install the [[https://www.freshports.org/graphics/drm-kmod/|drm-kmod]] package ''%%$ sudo pkg install drm-kmod%%''

  * Take note of the post-install package message as it contains important information - specifically add this to your /etc/rc.conf or /etc/rc.conf.d/radeon file: ''%%kld_list="/boot/modules/radeonkms.ko"%%''

  * Ensure that your UID is a member of the ''%%video%%'' group:
    * ''%%pw groupmod wheel -m <youruser>%%''

  * Restart your system; you should see the radeonkms.ko get loaded and a flash on your console as we switch over to the new display driver.

  * Start Xorg via your usual method (i.e. startx, GDM, etc.)
