Subject: [PATCH] detect-virt: use /proc/device-tree
|
|
|
17b0f1 |
|
|
|
17b0f1 |
Kernel doc Documentation/ABI/testing/sysfs-firmware-ofw says that
|
|
|
17b0f1 |
the /proc/device-tree symlink should be used, as opposed to
|
|
|
17b0f1 |
directly accessing /sys/firmware/devicetree/base. The former is
|
|
|
17b0f1 |
ABI, but not the later.
