2015-07-22loader: use HAVE_LIBDRM instead of ! __NOT_HAVE_DRM_HEmil Velikov1-4/+4
Double negatives in English language are normally avoided, plus the former seems cleaner and more consistent. Signed-off-by: Emil Velikov <> Reviewed-by: Ian Romanick <>

2015-07-08loader: Look for any version of currently linked libudev.soChris Wilson1-18/+28
Since there was an ABI break and linking twice against and 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 but the application was linked against Signed-off-by: Chris Wilson <> Emil Velikov: I'm ever so slightly conserned that RTLD_NOLOAD is not part of the POSIX standard, thus it's missing on some platforms (*BSD seems ok, while Solaris, MacOS are not).

2014-07-01loader: Use drirc device_id parameter in complement to DRI_PRIMEAxel Davy1-0/+27
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.

2014-07-01loader: add gpu selection code via DRI_PRIME.Axel Davy1-0/+185
v2: Fix the leak of device_name v3: Rebased It enables to use the DRI_PRIME env var to specify which gpu to use. 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 <> Reviewed-by: Emil Velikov <> Signed-off-by: Dave Airlie <>

2014-05-29loader: allow attempting more than one method of PCI identification.Gary Wong1-18/+46
loader_get_pci_id_for_fd() and loader_get_device_name_for_fd() now attempt all available strategies to identify the hardware, instead of conditionally compiling in a single test. The existing libudev and DRM approaches have been retained, attempting first libudev (if available) and then DRM (if necessary). Signed-off-by: Gary Wong <> Reviewed-by: Emil Velikov <>

2014-01-27loader: Use dlsym to get our udev symbols instead of explicit linking.Eric Anholt1-0/+42
Steam links against, while we're linking against The result is that the symbol names (which are the same in the two libraries) end up conflicting, and some of the usage of .so.1 calls the .so.0 bits, which have different internal structures, and segfaults happen. By using a dlopen() with RTLD_LOCAL, we can explicitly look for the symbols we want, while they get the symbols they want.

2014-01-20logger: s/\<log\>/log_/José Fonseca1-13/+13
Currently the MSVC build is broken because of conflicting definitions of 'log' function. I didn't investigate thoroughly, but I suspect the it is conflicting standard math.h's log. log_ is admittedly not a great name, but it is better than a broken build. A better one can be used in a follow-on build.

Mesa provides the flexibility of building without the need to have libdrm present on the system.

This patch converts Android's _EGL_NO_DRM to __NOT_HAVE_DRM_H to provide consistency with the other cases within mesa, allows compilation of libloader on libdrm-less scons and conditionally links against libdrm if present under automake.
