We've been getting occasional oops running a 32-bit kernel on a certain
system in our RHEL test hw. It appears that we fail to get sufficent ioremap
space for the framebuffer, and this leads to an oops.
This patch should fix the oops and leave a message in the logs we can
check for.
A future fix would probably to resize the console to a size that we can
ioremap.

This fixes page-flip-related flickering observed on Iconia Tab W500.
The update_pending status returned by radeon_page_flip is very accurate on
Avivo-based ASICs when vpos is negative.
Experiments were conducted on several ASIC generations ranging from RS690
to Cayman where the page flip was artificially timed to occur at a specific
vpos. With negative vpos, overriding update_pending always lead to
flickering.
The same experiment on RV380 and RV410 showed that update_pending is not
accurate with negative vpos. In most cases update_pending == 1 is returned
although the flip would complete before the start of the next frame.
Therefore I left the behaviour unchanged for pre-AVIVO ASICs for
performance reasons, although this may result in flickering in rare cases.
This change also makes the logic a little easier to understand.

For the simple KMS driver case we need some more info about what the preferred

If you need something really fancy you should be writing a real X.org driver.
v2: drop cursor information, just return an error from the cursor ioctls
and we can make userspace fallback to sw cursor in that case, cursor

Some integrated ATI Radeon chipset implementations with add-on HDMI card
(e. g. Asus M2A-VM HDMI) indicate the availability of a DDC even
when the add-on card is not plugged in or HDMI is disabled in BIOS setup.
In this case, drm_get_edid() and drm_edid_block_valid() periodically
dump data and kernel errors into system log files and onto terminals.
For these connectors DDC probing is extended by a check for a correct
EDID header. Only in case a valid EDID header is also found, the
(HDMI or DVI) connector will be used by the Radeon driver. This prevents
the kernel driver from useless flooding of logs and terminal sessions with
EDID dumps and error messages.
This patch adds a flag 'requires_extended_probe' to the radeon_connector
structure. In function radeon_connector_needs_extended_probe() this flag
can be set on a chipset family/vendor/connector type specific basis.
In addition, function radeon_ddc_probe() has been adapted to perform
extended DDC probing if required by the connector's flag.
Requires function drm_edid_header_is_valid() in DRM module provided by
[PATCH] drm: Separate EDID Header Check from EDID Block Check.
Tested for kernel 2.6.35, 2.6.38 and 3.0 on Asus M2A-VM HDMI board

This patch adds new functions for use by the drm core:
.get_vblank_timestamp() provides a precise timestamp
for the end of the most recent (or current) vblank
interval of a given crtc, as needed for the DRI2
implementation of the OML_sync_control extension.
It is a thin wrapper around the drm function
drm_calc_vbltimestamp_from_scanoutpos() which does
almost all the work and is shared across drivers.
.get_scanout_position() provides the current horizontal
and vertical video scanout position and "in vblank"
status of a given crtc, as needed by the drm for use by
drm_calc_vbltimestamp_from_scanoutpos().
The function is also used by the dynamic gpu reclocking
code to determine when it is safe to reclock inside vblank.
For that purpose radeon_pm_in_vbl() is modified to
accomodate a small change in the function prototype of
the radeon_get_crtc_scanoutpos() which is hooked up to
.get_scanout_position().
This code has been tested on AVIVO hardware, a RV530
(ATI Mobility Radeon X1600) in a Intel Core-2 Duo MacBookPro
and some R600 variant (FireGL V7600) in a single cpu
AMD Athlon 64 PC.

radeon_get_crtc_scanoutpos() returns the current horizontal
and vertical scanout position of a crtc. It also reports if
the display scanout is currently inside the vblank area.
hpos reports current horizontal pixel scanout position.
vpos reports the current scanned out line as a value >= 0
in active scanout. If the scanout is inside vblank area, it
reports a negative value, the number of scanlines until
end of vblank aka start of active scanout, e.g., -3 ==
"At most 3 scanlines until end of vblank".
This code is derived from radeon_pm_in_vbl(), tested on
R500 and R600.
