loader: cleanup copyright section

2016-10-18T16:06:32+00:00

With previous patches nearly all the original code (as seen in the
various loaders) is gone.

Update the copyright/license section to reflect that.

loader: remove loader_get_driver_for_fd() driver_type

2016-10-18T16:06:29+00:00

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()

2016-10-18T16:06:26+00:00

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).

loader: reimplement loader_get_user_preferred_fd via libdrm

2016-10-18T16:06:10+00:00

Currently not everyone has libudev and with follow-up patches we'll
completely remove the divergent codepaths.

Use the libdrm drm device API to construct the required ID_PATH_TAG-like
string, to preserve the current functionality for libudev users and
allow others to benefit from it as well.

v2: Drop ranty comments, pick the correct device
v3: \n -> \0 in PCI_ID_PATH_TAG_LENGTH comment (Axel).
v4: Use snprintf (Nicolai)

loader: slim down loader_get_pci_id_for_fd implementation(s)

2016-10-18T16:06:04+00:00

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. (Nicolai)

loader: fix sysfs uevent file parsing

2016-09-01T14:48:34+00:00

When trying to get a device name for an fd using sysfs, it would always fail
as it was expecting key/value pairs to be delimited by '\0', which is not the
case.
