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

2012-08-02T13:38:01+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)

2012-08-02T13:38:01+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.

drm/radeon: fix non revealent error message

2012-08-02T13:38:01+00:00

commit 8d1c702aa0b2c4b22b0742b72a1149d91690674b upstream.

We want to print link status query failed only if it's
an unexepected fail. If we query to see if we need
link training it might be because there is nothing
connected and thus link status query have the right
to fail in that case.

To avoid printing failure when it's expected, move the
failure message to proper place.

drm/radeon: Try harder to avoid HW cursor ending on a multiple of 128 columns.

2012-08-02T13:37:53+00:00

commit f60ec4c7df043df81e62891ac45383d012afe0da upstream.

This could previously fail if either of the enabled displays was using a
horizontal resolution that is a multiple of 128, and only the leftmost column
of the cursor was (supposed to be) visible at the right edge of that display.

The solution is to move the cursor one pixel to the left in that case.

Without this bit sets we get broken rendering and
lockups.

fglrx sets this bit.

drm/radeon: properly program gart on rv740, juniper, cypress, barts, hemlock

commit 0b8c30bc4943137a4a36b9cb059b1cc684f5d702 upstream.

Need to program an additional VM register.  This doesn't not currently
cause any problems, but allows us to program the proper backend
map in a subsequent patch which should improve performance on these
asics.

drm/radeon: fix bank information in tiling config

2012-06-10T13:41:53+00:00

commit 29d654067a98c1cb8874c774e5fd799a038af8a6 upstream.

While there are cards with more than 8 mem banks, the max
number of banks from a tiling perspective is 8, so cap
the tiling config at 8 banks.

drm/radeon: fix XFX quirk

2012-06-10T13:41:43+00:00

commit 1ebf169ad4dc68f18cc0dab35163b0f324fc6c41 upstream.

Only override the ddc bus if the connector doesn't have
a valid one.  The existing code overrode the ddc bus for
all connectors even if it had ddc bus.

Fixes ddc on another XFX card with the same pci ids that
was broken by the quirk overwriting the correct ddc bus.
