Attempting to try and turn off disconnected display hw in the
hotput handler lead to more problems than it helped. For
now just register an event and only attempt the do something
interesting with DP. Other connectors are just too problematic:
- Some systems have an HPD pin assigned to LVDS, but it's rarely
if ever connected properly and we don't really care about hpd
events on LVDS anyway since it's always connected.
- The HPD pin is wired up correctly for eDP, but we don't really
have to do anything since the events since it's always connected.
- Some HPD pins fire more than once when you connect/disconnect
- etc.

At least some Apples program the GPU into a state that wedges the engine
once userspace starts trying to perform accelerated operations. Executing
the Atom init scripts gets the hardware back into a working state. The
same hardware works fine when booted via BIOS emulation, so let's just
execute the init scripts on Apples when we're using EFI.

We have two sources of information about panel capabilities on mobile
radeon - the BIOS, which gives us a native mode, and the panel's preferred
mode. In theory these two will always match, but there's some corner cases
where the BIOS hasn't been fully initialised and so the native mode in it
ends up with default values. However, if we get a panel with reasonable
EDID, it's probably the case that the panel's preferred mode does actually
represent the panel capabilities. This patch handles that case by replacing
the native mode with the panel's preferred mode if the resolutions don't
match. Systems without a valid internal panel EDID will still use the BIOS
native mode.

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.

memory and reading ring entries based on that value (ie, we need to

enough to get that barrier but I prefer keeping an explicit one just

The writeback ring pointer and IH ring pointer are read using le32_to_cpu
so we do not want the chip to byteswap them on big-endian.
We still want to byteswap the ring itself and the IBs, so we don't touch
that but we remove setting of the byteswap bits in CP_RB_RPTR_ADDR and
IH_CNTL.
In general, for things like that where we control all the accessors easily,
we are better off doing the swap in SW rather than HW. Paradoxally, it does
keep the code closer to x86 and avoid using poorly tested HW features.
I also changed the use of RADEON_ to R600_ in a couple of cases to be more
consistent with the surrounding code.

I have read somewhere that the default are 32 bits. So if the

Sometimes the i2c test in i2c_bit_add_bus fails
if this happens we fail to register the i2c adapter and
eventually fail to add the connector. If i2c fails,
add the connector to the user can at least force
it on.
Note that some distros set i2c-algo-bit.bit_test to 1 by
default which sometimes fails preventing the ddc i2c adapter
from being added. The i2c adapter works even if the bit test
fails, probably due to pre/post_xfer not getting called in
the test_bit function. I have another patch to follow

On some servers there is a hardcoded EDID provided
in the vbios so that the driver will always see a
display connected even if something like a KVM
prevents traditional means like DDC or load
detection from working properly. Also most
server boards with DVI are not actually DVI, but
DVO connected to a virtual KVM service processor.
If we fail to detect a monitor via DDC or load
detection and a hardcoded EDID is available, use
it.
Additionally, when using the hardcoded EDID, use
a copy of it rather than the actual one stored
in the driver as the detect() and get_modes()
functions may free it if DDC is successful.
This fixes the virtual KVM on several internal
servers.

So we used to use lpfn directly to restrict VRAM when we couldn't
access the unmappable area, however this was removed in
93225b0d7b as it also restricted
the gtt placements. However it was only later noticed that this
broke on some hw.
This removes the active_vram_size, and just explicitly sets it
when it changes, TTM/drm_mm will always use the real_vram_size,
and the active vram size will change the TTM size used for lpfn
setting.
We should re-work the fpfn/lpfn to per-placement at some point
I suspect, but that is too late for this kernel.
