* loader: Add support for platform and host1x bussesThierry Reding2018-03-021-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM SoCs usually have their DRM/KMS devices on the platform bus, so add support for this bus in order to allow use of the DRI_PRIME environment variable with those devices. While at it, also support the host1x bus, which is effectively the same but uses an additional layer in the bus hierarchy. Note that it isn't enough to support the bus that has the rendering GPU because the loader code will also try to construct an ID path tag for a scanout-only device if it is the default that is being opened. The ID path tag for a device can be obtained by running udevadm info on the device node, as shown in this example on NVIDIA Tegra: $ udevadm info /dev/dri/card0 | grep ID_PATH_TAG E: ID_PATH_TAG=platform-50000000_host1x The corresponding OF_FULLNAME property, from which the ID_PATH_TAG is constructed, can be found in the sysfs "uevent" attribute for the card0 device's parent: $ grep OF_FULLNAME /sys/devices/platform/50000000.host1x/drm/uevent OF_FULLNAME=/host1x@50000000 Similarily, /dev/dri/card1 corresponds to the GPU: $ udevadm info /dev/dri/card1 | grep ID_PATH_TAG E: ID_PATH_TAG=platform-57000000_gpu and: $ grep OF_FULLNAME /sys/devices/platform/57000000.gpu/uevent OF_FULLNAME=/gpu@57000000 Changes in v2: - avoid confusing pre-increment in strdup() - add examples of tags to commit message Reviewed-by: Eric Engestrom <[email protected]> Reviewed-by: Emil Velikov <[email protected]> Signed-off-by: Thierry Reding <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | 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.
