* kmscube: add AMD_performance_monitor supportRob Clark2020-03-071-2/+18
| | | | | Only wired up for shadertoy mode, other modes aren't likely to be interesting.
* kmscube: add option to run for specified # of framesRob Clark2020-03-071-3/+9
|
* add shadertoy modeRob Clark2020-03-071-2/+10
| | | | | | Doesn't handle shadertoy shaders which use textures for inputs. That probably wouldn't be straightforward without using the web API to fetch and introspect the shader. But that sounds like a lot more work.

* kmscube: make fb/gl config format settable on cmdlineIlia Mirkin2019-08-301-1/+19
| | | | | | | | Instead of changing the code each time, allow the fourcc to be passed in as an argument. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Reviewed-by: Rob Clark <robdclark@gmail.com>
* drm: Find a proper modeset device, is none is providedEzequiel Garcia2019-07-301-1/+1
| | | | | | | | | | | | | | | | Instead of having a fixed /dev/dri/card0 default, iterate over primary devices until one with modeset capabilities is found. This is quite useful when a render-only driver (such as lima or panfrost) was registered before the modeset driver, taking over /dev/dri/card0. While here, add a warning for devices explicitly set via -D, by checking if they look like a modeset device.

* kmscube: add command-line selection of video modeAntonio Borneo2019-07-231-5/+25
| | | | | | | | | | | | | | The mode of type "DRM_MODE_TYPE_PREFERED" can be miss-configured, making kmscube not working. Plus, user could need to test the other available video modes at the connector. Add a command line flag to specify the video mode. If the mode is not present, print an informative message and fall-back to the default behaviour (preferred mode or highest resolution mode).

* Rework default modifier handlingEmil Velikov2018-04-021-1/+1
| | | | | | | | | | | | | Currently the default modifier is MOD_INVALID. At a later stage, if the modifier is the same (the user may have explicit selected MOD_INVALID), we'll fallback to MOD_LINEAR. Simplify things to a) use MOD_LINEAR by default b) use the user modifier - even if they request MOD_INVALID.

* add video cubeRob Clark2017-03-271-2/+18
| | | | | | | | | | | | | | Uses gstreamer for a simple decoder. If decoder can give us dma-buf's directly, we'll directly use that as a texture (zero copy), otherwise memcpy into a buffer from gbm. This should work with both hw and sw decoders. Probably room for improvement. And the interface between gl and the decoder is pretty simple so I suppose other decoders would be possible. (But hopefully they could already be supported via gstreamer.) Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com>

* Don't check for every kind of DRM driver. Just use the CARD !Myy2017-01-121-23/+1
| | | | | | | | | | | | The DRM checks are WAY too fragile. Testing every potential DRM driver available goes against what device drivers are for. They're supposed to provide transparent abstractions. Currently the patch uses only card0. Some people *might* have multiple graphics cards. In this case, feel free to add options to choose the right DRM device entry (/dev/dri/cardX). Signed-off-by: Myy <myy@miouyouyou.fr>

| | | | | | | | | | For some reason, ARM Mali Wayland/DRM drivers does not seem to support eglGetDisplay(gbm.dev) and prefers instead eglGetPlatformDisplayEXT(EGL_PLATFORM_GBM_KHR, gbm.dev, NULL). Used the Weston DRM and GL renderers as reference. Signed-off-by: Myy <myy@miouyouyou.fr>

* Make search for a crtc more robustNicholas Bishop2016-09-071-4/+51
| | | | | | | | | | | | | | Running the kmscube test on qemu with "-vga virtio" fails for me with a "no encoder!" error. Fixed by searching all crtcs for one that is supported by one of the encoders in the connector. This code is only used if the existing `encoder->crtc_id` check is zero, so there should be no regression for systems where it already works. I think this should match the advice given here: https://dvdhrm.wordpress.com/2012/09/13/linux-drm-mode-setting-api/

* Prefer mode of type "DRM_MODE_TYPE_PREFERED"Gabriel Laskar2014-11-041-1/+6
| | | | | | | | | | | | On screen with native resolution of 1440x900, there is sometime a compatibility mode for 1280x1024, with shrinked output and vertical bands to maintain ratio. If we select the resolution with the higher area, we select the compatibility mode and not the native resolution. When using mode_type == DRM_MODE_TYPE_PREFERED, we avoid that issue.
