- Choose this option if you want kernel modesetting enabled by default.
+ Choose this option if you still need userspace modesetting.
- This is a completely new driver. It's only part of the existing drm
- for compatibility reasons. It requires an entirely different graphics
- stack above it and works very differently from the old drm stack.
- i.e. don't enable this unless you know what you are doing it may
- cause issues or bugs compared to the previous userspace driver stack.
-
- When kernel modesetting is enabled the IOCTL of radeon/drm
- driver are considered as invalid and an error message is printed
- in the log and they return failure.
-
- KMS enabled userspace will use new API to talk with the radeon/drm
- driver. The new API provide functions to create/destroy/share/mmap
- buffer object which are then managed by the kernel memory manager
- (here TTM). In order to submit command to the GPU the userspace
- provide a buffer holding the command stream, along this buffer
- userspace have to provide a list of buffer object used by the
- command stream. The kernel radeon driver will then place buffer
- in GPU accessible memory and will update command stream to reflect
- the position of the different buffers.
-
- The kernel will also perform security check on command stream
- provided by the user, we want to catch and forbid any illegal use
- of the GPU such as DMA into random system memory or into memory
- not owned by the process supplying the command stream.
+ Userspace modesetting is deprecated for quite some time now, so
+ enable this only if you have ancient versions of the DDX drivers.
