drm/radeon/kms/evergreen: set accel_enabled

2010-06-07T23:34:42+00:00

This is needed to enable accel in the ddx.  However,
due to a bug in older versions of the ddx, it relies
on accel being disabled in order to load properly on
evergreen chips.  To maintain compatility, we add a new
get accel param and call that from the ddx.  The old one
always returns false for evergreen cards.

[this fixes a regression with older userspaces on newer kernels].

drm/radeon/kms: add query for crtc hw id from crtc id to get info V2

2010-05-18T05:59:08+00:00

Userspace need to know the hw crtc id (0, 1, 2, ...) from the drm
crtc id. Bump the minor version so userspace can enable conditionaly
features depend on this.

V2 use num_crtc and avoid DRM_ERROR

drm/radeon/kms: don't fail if we fail to init GPU acceleration

2009-09-18T06:01:57+00:00

Userspace can query if acceleration is working or not true get
info ioctl and could fallback to software if for some reason
kernel failed to initialize KMS. This should allow to give a
working KMS setup in all case (even with non functionning accel).

drm/radeon/kms: implement the bo busy ioctl properly.

2009-08-20T23:51:30+00:00

The previous patch assumes the ioctl already existed, when
it actually didn't.

It also didn't return the correct error code.

drm/radeon/kms: implement bo busy check + current domain

2009-08-17T02:28:56+00:00

This implements the busy ioctl along with a current domain check.
returns 0 or -EBUSY
puts the current domain no matter what the answer.

drm/radeon/kms: add initial colortiling support.

2009-07-29T05:42:18+00:00

This adds new set/get tiling interfaces where the pitch
and macro/micro tiling enables can be set. Along with
a flag to decide if this object should have a surface when mapped.

The only thing we need to allocate with a mapped surface should be
the frontbuffer. Note rotate scanout shouldn't require one, and
back/depth shouldn't either, though mesa needs some fixes.

It fixes the TTM interfaces along Thomas's suggestions, and I've tested
the surface stealing code with two X servers and not seen any lockdep issues.

I've stopped tiling the fbcon frontbuffer, as I don't see there being
any advantage other than testing, I've left the testing commands in there,
just flip the fb_tiled to true in radeon_fb.c

Open: Can we integrate endian swapping in with this?

Future features:
texture tiling - need to relocate texture registers TXOFFSET* with tiling info.

This also merges Michel's cleanup surfaces regs at init time patch
even though it makes sense on its own, this patch really relies on it.

Some PowerMac firmwares set up a tiling surface at the beginning of VRAM
which messes us up otherwise.
that patch is:
