      drm/kms/radeon: pick digitial encoders smarter. (v3) · f28cf339
      由 Dave Airlie 提交于 
      booting a Lenovo W500 with LVDS + DP outputs showed up a TODO we had
on our list, to pick a correct digital encoder block. The LVTMA
encoder requires the second digital encoder, all others can use any
encoder at all.

This fixes the digital encoder selection logic to enable LVDS/DP combos
to work okay.

V2: fix silly addition of connector dig_block and cleanup the other
places in the code that pick the encoder.

V3: rename to dig_encoder and clean up further - also fix
the picking algorithm.

tested on Lenovo W500 + desktop 3650 cards.

      drm/radeon/kms: use active device to pick connector for encoder · 43c33ed8
      由 Dave Airlie 提交于 
      On the W500 we have UNIPHY routed to both DVI and DP, this seems
to always pick the DVI connector which means link training fails.

Switch to using active device to pick the connector, this seems
like it should be safe from a code review, and it fixes things
a bit more here.

      drm/radeon/kms: add initial connector properties · 445282db
      由 Dave Airlie 提交于 
      This adds:
coherent mode: TMDS coherent mode for atom cards.
scaling mode: LVDS scaler mode
load detect: DAC load detection, DVI-I, VGA, TV
tmds pll: legacy TMDS pll selection
tv standard: TV standard selection.

for later: other TV ones? dvi subconnector selection using std prop

[contains fixes pointed out on dri-devel for atom bios mixups
 by Michel]

      drm/radeon: introduce kernel modesetting for radeon hardware · 771fe6b9
      由 Jerome Glisse 提交于 
      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).
