* loader: remove loader_get_driver_for_fd() driver_typeEmil Velikov2016-10-181-7/+1
| | | | | | | | | | | | | | Reminiscent from the pre-loader days, were we had multiple instances of the loader logic in separate places and one could build a "GALLIUM_ONLY" version. Since that is no longer the case and the loaders (glx/egl/gbm) do not (and should not) require to know any classic/gallium specific we can drop the argument and the related code.

* loader: remove final sysfs codepath in loader_get_device_name_for_fd()Emil Velikov2016-10-181-46/+1
| | | | | | | | | | | | | | Effectively everyone with actual hardware and/or requesting the "device_name" requires a working libdrm. Thus they could/should already be using the (now only) codepath. Apart from the code simplification, we can slim down our configure.ac even further. But that will be done in separate patch(es).

| | | | | | | | | | | | | | | | Currently mesa has three code paths in the loader - libudev, manual sysfs and drm ioctl one. Considering the issues we had with libudev - strip those down in favour of the libdrm drm device API. The latter can be implemented in any way depending on the platform and can be reused by others. v2: Use correct message on drmGetDevice failure.

* loader: Look for any version of currently linked libudev.soChris Wilson2015-07-081-18/+28
| | | | | | | | | | | | | | | | | | | | | | Since there was an ABI break and linking twice against libudev.so.0 and libudev.so.1 causes the application to quickly crash, we first check if the application is currently linked against libudev before dlopening a local handle. However for backwards/forwards compatability, we need to inspect the application for current linkage against all known versions first. Not doing so causes a crash when both libraries are present and so mesa chooses libudev.so.1 but the application was linked against libudev.so.0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | DRI_PRIME is not very handy, because you have to launch the executable with it set, which is not always easy to do. By using drirc, the user specifies the target executable and the device to use. After that the program will be launched everytime on the target device. For example if .drirc contains: <driconf> <device driver="loader"> <application name="Glmark2" executable="glmark2"> <option name="device_id" value="pci-0000_01_00_0" /> </application> </device> </driconf> Then glmark2 will use if possible the render-node of ID_PATH_TAG pci-0000_01_00_0. v2: Fix compilation issue v3: Add "-lm" and rebase.

Two syntax are supported: If DRI_PRIME is 1 it means: take any other gpu than the default one. If DRI_PRIME is the ID_PATH_TAG of a device: choose this device if possible. The ID_PATH_TAG is a tag filled by udev. You can check it with 'udevadm info' on the device node. For example it can be "pci-0000_01_00_0". Render-nodes need to be enabled to choose another gpu, and they need to have the ID_PATH_TAG advertised. It is possible for not very recent udev that the tag is not advertised for render-nodes, then ones need to add a file containing: SUBSYSTEM=="drm", IMPORT{builtin}="path_id" in /etc/udev/rules.d/ Signed-off-by: Axel Davy <[email protected]> Reviewed-by: Emil Velikov <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
