drm_gem_object_init() and drm_gem_private_object_init() do exactly the
same (except for shmem alloc) so make the first use the latter to reduce
code duplication.
Also drop the return code from drm_gem_private_object_init(). It seems
unlikely that we will extend it any time soon so no reason to keep it
around. This simplifies code paths in drivers, too.
Last but not least, fix gma500 to call drm_gem_object_release() before
freeing objects that were allocated via drm_gem_private_object_init().
That isn't actually necessary for now, but might be in the future.

drm/i915: fixup 12bpc hdmi dotclock handling
I've errornously claimed that we don't yet support the hdmi 1.4
dotclocks > 225 MHz on Haswell. But a bug report and a closer look at
the wrpll table showed that we've supported port clocks up to 300MHz.
With the new code to dynamically compute wrpll limits we should have
no issues going up to the full 340 MHz range of hdmi 1.4, so let's
just use that to fix this regression. That'll allow 4k over hdmi for
free!
v2: Drop the random hunk that somehow slipped in.
v3: Cantiga has the original HDMI dotclock limit of 165MHz. And also
patch up the mode filtering. To do so extract the dotclock limits into
a little helper function.
v4: Use 300MHz (from Bspec) instead of 340MHz (upper limit for hdmi
1.3), apparently hw is not required to be able to drive the highest
dotclocks. Suggested by Damien.

Noticed that my old Radeon 7500 hung after printing
drm: GPU not posted. posting now...
when it wasn't selected as the primary card the BIOS. Some digging
revealed that it was hanging in combios_parse_mmio_table() while
parsing the ASIC INIT 3 table. Looking at the BIOS ROM for the card,
it becomes obvious that there is no ASIC INIT 3 table in the BIOS.
The code is just processing random garbage. No surprise it hangs!
Why do I say that there is no ASIC INIT 3 table is the BIOS? This
table is found through the MISC INFO table. The MISC INFO table can
be found at offset 0x5e in the COMBIOS header. But the header is
smaller than that. The COMBIOS header starts at offset 0x126. The
standard PCI Data Structure (the bit that starts with 'PCIR') lives at
offset 0x180. That means that the COMBIOS header can not be larger
than 0x5a bytes and therefore cannot contain a MISC INFO table.
I looked at a dozen or so BIOS images, some my own, some downloaded from:
<http://www.techpowerup.com/vgabios/index.php?manufacturer=ATI&page=1>
It is fairly obvious that the size of the COMBIOS header can be found
at offset 0x6 of the header. Not sure if it is a 16-bit number or
just an 8-bit number, but that doesn't really matter since the tables
seems to be always smaller than 256 bytes.
So I think combios_get_table_offset() should check if the requested
table is present. This can be done by checking the offset against the
size of the header. See the diff below. The diff is against the WIP
OpenBSD codebase that roughly corresponds to Linux 3.8.13 at this
point. But I don't think this bit of the code changed much since
then.

Hello,
got another card with "too bright" problem:
Sapphire Radeon VE 7000 DDR (VGA+S-Video)
lspci -vnn:
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV100 QY [Radeon 7000/VE] [1002:5159] (prog-if 00 [VGA controller])
Subsystem: PC Partner Limited Sapphire Radeon VE 7000 DDR [174b:7c28]
The patch below fixes the problem for this card.
But I don't like the blacklist, couldn't some heuristic be used instead?
The interesting thing is that the manufacturer is the same as the other card
needing the same quirk. I wonder how many different types are broken this way.
The "wrong" ps2_pdac_adj value that comes from BIOS on this card is 0x300.
====================

Values from BIOS are wrong, causing too bright colors.

Atm the crtc helper implementation of set_config has really

dpms on.

drm: Only set DPMS ON when actually configuring a mode

drm: Set connector DPMS status to ON in drm_crtc_helper_set_config
And if you'd dig around in the i915 driver code there's even more fun
around forcing dpms on and losing our heads and temper of the
resulting inconsistencies. Especially the DP re-training code had tons
of funny stuff in it.
v2: So v1 totally blew up on resume on my radeon system here. After
much head-scraching I've figured out that the radeon resume functions
resumes the console system _before_ it actually restores all the
modeset state. And resuming the console systems means that fbdev doeas
an immediate ->set_par call.
Now up to this patch that ->set_par did absolutely nothing: All the
old sw state from pre-suspend was still around (since the modeset
reset wasn't done yet), which means that the set_config calls done as
a result of the ->set_par where all treated as no-ops (despite that
the real hw state was obviously something completely different).
Since v1 of this patch just added a bunch of ->dpms calls if the crtc
was enabled, those set_config calls suddenly stopped being no-ops. But
because the hw state wasn't restored the ->dpms callbacks resulted in
decent amounts of hilarity and eventual full hangs.
Since I can't review all kms drivers for such tricky ordering
constraints v2 opts for a different approach and forces a full modeset
if the connector dpms state isnt' DPMS_ON. Since the ->dpms callbacks
implemented by the modeset helpers update the connector->dpms property
we have the same effect of ensuring that the pipe is ultimately turned
on, even if we just end up updating the fb. This is the same approac
we ended up using in the intel driver.
Note that besides i915.ko only all other drivers eventually call
drm_helper_connector_dpms with the exception of vmwgfx, which does not
support dmps at all.
