drm/radeon: Deprecate UMS support v2

2013-01-31T21:24:47+00:00

KMS support is out and stable for a couple of years now and
the userspace code has deprecated or abandoned the old UMS interface.

So make the KMS interface the default and deprecate the UMS interface
in the kernel as well.

v2: rebased on alex/drm-next-3.9-wip

radeon: expose backlight class device for legacy LVDS encoder

2011-03-23T00:43:59+00:00

Allows e.g. power management daemons to control the backlight level. Inspired
by the corresponding code in radeonfb.

[mjg@redhat.com: updated to add backlight type and make the connector the parent device]

drm/radeon/kms: change Kconfig text to reflect the new option.

2010-02-08T05:05:58+00:00

Ingo pointed out that we really don't give the user enough warning to make
a decision here. So revise the Kconfig text with a better warning.

drm/kms/radeon: make kms default a runtime option

2009-09-08T01:15:59+00:00

This makes the kms/enable disable a runtime not a build time
option.

drm/kms: fix kms helper license + Kconfig

2009-09-08T01:15:58+00:00

Allow the KMS module to work properly, and also rename
it to KMS_HELPER so its clearer what its for.

drm: split crtc/fb helpers into a separate module

2009-09-07T05:45:33+00:00

I really don't want to have core drm module rely on CONFIG_FB,
so this is the easiest answer.

drm/radeon: introduce kernel modesetting for radeon hardware

2009-06-15T02:01:53+00:00

Add kernel modesetting support to radeon driver, use the ttm memory
manager to manage memory and DRM/GEM to provide userspace API.
In order to avoid backward compatibility issue and to allow clean
design and code the radeon kernel modesetting use different code path
than old radeon/drm driver.

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. This part
of the code is still incomplete and this why we propose that patch
as a staging driver addition, future security might forbid current
experimental userspace to run.

This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX
(radeon up to X1950). Works is underway to provide support for R6XX,
R7XX and newer hardware (radeon from HD2XXX to HD4XXX).
