drm/i915: add _DSM support

2010-10-08T09:27:43+00:00

The _DSM method on the integrated graphics device can tell us which
connectors are muxable, so add support for making the call and parsing
out the connector info.

drm/i915: Use the VBT from OpRegion when available (v3)

2010-09-08T09:13:32+00:00

It is recommended that we use the Video BIOS tables that were copied
into the OpRegion during POST when initialising the driver. This saves
us from having to furtle around inside the ROM ourselves and possibly
allows the vBIOS to adjust the tables prior to initialisation.

On some systems, such as the Samsung N210, there is no accessible VBIOS
and the only means of finding the VBT is through the OpRegion.

v2: Rearrange the code so that ASLE is enabled along with ACPI
v3: Enable OpRegion parsing even without ACPI

drm/i915: Rename i915_opregion.c to intel_opregion.c

2010-09-08T09:13:31+00:00

It's part of the generic Intel driver infrastructure so rename it in
prepreparation for using it for VBT.

drm/i915: Enable aspect/centering panel fitting for Ironlake.

drm/i915: Move the eviction logic to its own file.

2010-08-09T18:24:32+00:00

The eviction code is the gnarly underbelly of memory management, and is
clearer if kept separated from the normal domain management in GEM.

drm/i915: Move ringbuffer-related code to intel_ringbuffer.c.

2010-05-26T19:36:00+00:00

This is preparation for supporting multiple ringbuffers on Ironlake.
The non-copy-and-paste changes are:
- de-staticing functions
- I915_GEM_GPU_DOMAINS moving to i915_drv.h to be used by both files.
- i915_gem_add_request had only half its implementation
  copy-and-pasted out of the middle of it.

drm/i915: Fix out of tree builds

2010-05-10T20:38:32+00:00

Fixes up include paths for i915_trace.h by setting additional CFLAGS
for i915_trace_points.c to include the $src directory. The required
TRACE_INCLUDE_PATH is then "."

Merge remote branch 'anholt/drm-intel-next' into drm-linus

2009-12-08T04:03:47+00:00

This merges the upstream Intel tree and fixes up numerous conflicts
due to patches merged into Linus tree later in -rc cycle.

Conflicts:
	drivers/char/agp/intel-agp.c
	drivers/gpu/drm/drm_dp_i2c_helper.c
	drivers/gpu/drm/i915/i915_irq.c

drm/intel: refactor DP i2c support and DP common header to drm helper

2009-12-07T23:24:23+00:00

Both radeon and nouveau can re-use this code so move it up a level
so they can. However the hw interfaces for aux ch are different
enough that the code to translate from mode, address, bytes
to actual hw interfaces isn't generic, so move that code into the
Intel driver.

drm/i915: implement drmmode overlay support v4

2009-11-05T22:47:08+00:00

This implements intel overlay support for kms via a device-specific
ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on
dri-devel). We've reached the conclusion that such an infrastructure
only makes sense when multiple kms overlay implementations exists,
which atm don't (and it doesn't look like this is gonna change).

Open issues:
- Runs in sync with the gpu, i.e. unnecessary waiting. I've decided
  to wait on this because the hw tends to hang when changing something
  in this area. I left some dummy functions as infrastructure.
- polyphase filtering uses a static table.
- uses uninterruptible sleeps. Unfortunately the alternatives may
  unnecessarily wedged the hw if/when we timeout too early (and
  userspace only overloaded the batch buffers with stuff worth a few
  secs of gpu time).

Changes since v1:
- fix off-by-one misconception on my side. This fixes fullscreen
  playback.
Changes since v2:
- add underrun detection as spec'ed for i965.
- flush caches properly, fixing visual corruptions.
Changes since v4:
- fix up cache flushing of overlay memory regs.
- killed require_pipe_a logic - it hangs the chip.
