This is already our common idiom for opening files with CLOEXEC and

Rob Clark 9153dd4b7e loader: not having a pci-id should not be a warn
If there is no pci-id, which is valid for vc4 and freedreno, just emit
an info msg.  Keep malformed but existing pci-id's as a warning.

Mostly just to clean up a warning that confuses users for the non-pci
devices.

Axel Davy 3ecd9e1a93 loader: Use drirc device_id parameter in complement to DRI_PRIME
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.

Axel Davy 7ab925a6aa loader: add gpu selection code via DRI_PRIME.
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/

Eric Anholt 4556c73470 loader: Use dlsym to get our udev symbols instead of explicit linking.
Steam links against libudev.so.0, while we're linking against
libudev.so.1.  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.

log_ is admittedly not a great name, but it is better than a broken build.

    loader: introduce the loader util lib

By isolating libdrm code by #ifndef __NOT_HAVE_DRM_H we
can have libdrm-less builds on across all build systems.

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.
