Revert "drm/radeon: fix bo creation retry path"

2012-09-14T16:59:36+00:00

commit 676bc2e1e4f9072f7a640d5b7c99ffdf9709a6e7 upstream.

This reverts commit d1c7871ddb1f588b8eb35affd9ee1a3d5e11cd0c.

ttm_bo_init() destroys the BO on failure. So this patch makes
the retry path work with freed memory.  This ends up causing
kernel panics when this path is hit.

commit dca571a6a4edda1f61ba7ecb47431a22245490a3 upstream.

The sixteen bank case wasn't handled here, leading to GPU
crashes because of userspace miscalculation.

drm/radeon: do not reenable crtc after moving vram start address

2012-08-26T02:31:40+00:00

commit 81ee8fb6b52ec69eeed37fe7943446af1dccecc5 upstream.

It seems we can not update the crtc scanout address. After disabling
crtc, update to base address do not take effect after crtc being
reenable leading to at least frame being scanout from the old crtc
base address. Disabling crtc display request lead to same behavior.

So after changing the vram address if we don't keep crtc disabled
we will have the GPU trying to read some random system memory address
with some iommu this will broke the crtc engine and will lead to
broken display and iommu error message.

So to avoid this, disable crtc. For flicker less boot we will need
to avoid moving the vram start address.

This patch should also fix :

drm/radeon: properly handle crtc powergating

2012-08-26T02:31:40+00:00

commit 6c0ae2ab85fc4a95cae82047a7db1f688a7737ab upstream.

Need to make sure the crtc is gated on before modesetting.
Explicitly gate the crtc on in prepare() and set a flag
so that the dpms functions don't gate it off during
mode set.

Noticed by sylware on IRC.

drm/radeon: fix dpms on/off on trinity/aruba v2

2012-08-09T15:23:11+00:00

commit fcedac670c3da0d17aaa5db1708694971e8024a9 upstream.

The external encoder need to be setup again before enabling the
transmiter. This seems to be only needed on some trinity/aruba
to fix dpms on.

v2: Add comment, only setup again on dce6 ie aruba or newer.

drm/radeon: on hotplug force link training to happen (v2)

2012-08-09T15:23:11+00:00

commit ca2ccde5e2f24a792caa4cca919fc5c6f65d1887 upstream.

To have DP behave like VGA/DVI we need to retrain the link
on hotplug. For this to happen we need to force link
training to happen by setting connector dpms to off
before asking it turning it on again.

v2: agd5f
- drop the dp_get_link_status() change in atombios_dp.c
  for now.  We still need the dpms OFF change.

drm/radeon: fix hotplug of DP to DVI|HDMI passive adapters (v2)

2012-08-09T15:23:11+00:00

commit 266dcba541a1ef7e5d82d9e67c67fde2910636e8 upstream.

No need to retrain the link for passive adapters.

v2: agd5f
- no passive DP to VGA adapters, update comments
- assign radeon_connector_atom_dig after we are sure
  we have a digital connector as analog connectors
  have different private data.
- get new sink type before checking for retrain.  No
  need to check if it's no longer a DP connection.
