VSYNC

There are several mechanisms involved in tear-free rendering due to limitations in X.

3D driver environment variable

vblank_mode - selects whether or not the 3D application should synchronize to vblank.

DDX driver options

EnablePageFlip - This option enables the use of pageflipping (switching the display controller's base address pointer) rather than blits for GL buffer swaps. It only applies to fullscreen GL apps. Pageflipping is always synced to vblank at the moment.

SwapBuffersWait - This option prevents tearing for GL buffer swaps by waiting to update the front buffer until scanout has passed the area of the screen the GL buffer swap is going to blit to.

EXAVSync - This option prevents tearing for EXA operations by waiting to update the front buffer until scanout has passed the area of the screen the EXA operation is going to render to.

Xv Attribute

XV_VSYNC - This option prevents tearing when playing back videos using Xv by waiting to update the video image until scanout has passed the area of the screen displaying the video. It only prevents tearing if Xv is rendering directly to the front buffer. If you are using a compositer, this does not prevent tearing because Xv is rendering to an offscreen buffer and the compositor copied it to the front buffer.

KMS Power Management Options

Kernel 2.6.35 or newer is required. The pm code supports three basic methods:

"dynpm" "profile" "dpm"

You can select the methods via sysfs. Echo "dynpm" or "profile" to /sys/class/drm/card0/device/power_method. "dpm" support, must be selected at boot (via radeon.dpm=1) and is only supported on R6xx and newer asics.

Controlling the fan speed directly is not possible (and would be very dangerous), but it can be lowered by setting lower power profile.

The "dynpm" method dynamically changes the clocks based on the number of pending fences, so performance is ramped up when running GPU intensive apps, and ramped down when the GPU is idle. The reclocking is attemped during vertical blanking periods, but due to the timing of the reclocking functions, doesn't not always complete in the blanking period, which can lead to flicker in the display. Due to this, dynpm only works when a single head is active.

The "profile" method exposes five profiles that can be selected from:

"default" "auto" "low" "mid" "high"

Select the profile by echoing the selected profile to /sys/class/drm/card0/device/power_profile.

"default" uses the default clocks and does not change the power state. This is the default behavior.

"auto" selects between "mid" and "high" power states based on the whether the system is on battery power or not. The "low" power state are selected when the monitors are in the dpms off state.

"low" forces the gpu to be in the low power state all the time. Note that "low" can cause display problems on some laptops; this is why auto does not use "low" when displays are active.

"mid" forces the gpu to be in the "mid" power state all the time. The "low" power state is selected when the monitors are in the dpms off state.

"high" forces the gpu to be in the "high" power state all the time. The "low" power state is selected when the monitors are in the dpms off state. The "profile" method is not as agressive as "dynpm," but is currently much more stable and flicker free and works with multiple heads active.

The "dpm" method uses hardware on the GPU to dynamically change the clocks and voltage based on GPU load. It also enables clock and power gating.

Power management is supported on all asics (r1xx-evergreen) that include the appropriate power state tables in the vbios; not all boards do (especially older desktop cards). "dpm" is only supported on R6xx and newer asics.

Thermal sensors are implemented via external i2c chips or via the internal thermal sensor (rv6xx-evergreen only; supported in 2.6.36 or newer); not all OEMs implement a thermal sensor. To get the temperature on asics that use i2c chips, you need to load the appropriate hwmon driver for the sensor used on your board (lm63, lm64, etc.). The drm will attempt to load the appropriate hwmon driver. On boards that use the internal thermal sensor, the drm will set up the hwmon interface automatically. When the appropriate driver is loaded, the temperatures can be accessed via lm_sensors tools or via sysfs in /sys/class/hwmon.

Linux kernel parameters

Try modinfo -p radeon to find up-to-date parameters. To check default values look at drivers/gpu/drm/radeon/radeon_drv.c or drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c in Linux kernel source. To check current values look at /sys/class/drm/card*/device/driver/module/holders/radeon/parameters/ or /sys/class/drm/card/device/driver/module/holders/amdgpu/parameters/*

Documentation

1 Kernel 3.4 required

2 Depends on the OEM board. Max of 2 (evergreeen-SI) or 3 (CI) non-Displayport displays with independent timing.

3 Requires a 3D driver with shader support

4 RV770, RS780/880, R6xx require kernel 3.18

5 There are two versions of hybrd graphics: MUXed and MUX-less. MUXed have a display MUX to switch the displays between the discrete and integrated cards. MUXed systems can be switched using vgaswitcheroo. MUX-less do not have a display MUX and the displays are only connected to the integrated card. On MUX-less systems, the discrete card is solely for rendering, not display. X Server 1.14 is required to support rendering and display from different cards. Most new laptops (2011+) are MUX-less.

7 Kernel 3.10 required

12 Kernel 3.6 required

14 Needs piglit and Lightsmark testing before enabling by default, see mesa commit 12dcbd595

15 Currently enabled by default. It can be disabled by setting the environment variable R600_DEBUG=nohyperz.

16 Hardware doesn't support ARB NPOT textures fully.

17 Kernel 3.14 required. For older kernel, apply this kernel patch: http://www.spinics.net/lists/dri-devel/msg52745.html

18 LLVM 3.9 and Kernel 4.7 required

19 OpenGL 4.2 is currently only supported on CYPRESS, CAYMAN and ARUBA. All other chips are currently limited to OpenGL 3.3

20 LLVM 3.9 required

22 Older kernels require loading radeon with the audio parameter set to 1 (e.g., add radeon.audio=1 on the kernel command line in grub).

23 Kernel 3.3 required

24 Kernel 3.5 required

26 i2c chip

28 i2c chip or internal sensor

33 See http://dri.freedesktop.org/wiki/GalliumCompute

34 None

35 ARUBA only

36 No TV-out support on R4xx
