6375bda073 drm/radeon/kms: add retry limits for native DP aux defer
The previous code could potentially loop forever.  Limit
the number of DP aux defer retries to 4 for native aux
transactions, same as i2c over aux transactions.

d5811e8731 drm/radeon/kms: don't try to be smart in the hpd handler
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

same hardware works fine when booted via BIOS emulation, so let's just
execute the init scripts on Apples when we're using EFI.

13bb9430cd drm/radeon: Allow panel preferred EDID to override BIOS native mode
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.

e384fab8c6 drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC Lines (here: Asus M2A-VM HDMI)
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

We should have a read memory barrier between reading the WPTR from

ensure both loads are done in order by the CPU).

It could be argued that the MMIO reads in r600_ack_irq() might be
enough to get that barrier but I prefer keeping an explicit one just
in case.

  args.v6.ulCrtcPclkFreq.ulPixelClock = cpu_to_le32(clock / 10);

ulPixelClock is a 24-bit bitfield. This statement would thus
do a 32-bit swap of (clock / 10) and drop the top 8 bits which
are ... the LSB. Not what we want. Instead use masks & shifts.

edc02bffbd drm/radeon: Fix the definition of RADEON_BUF_SWAP_32BIT
(Note that this is duplicated under various other names such
as R600_BUF_SWAP_32BIT etc...). At least now all the definitions
agree.

f6a5693976 drm/radeon: Do an MMIO read on interrupts when not uisng MSIs
When not using MSIs, there is no guarantee that DMA from the device
has been fully flushed to point where it's visible to the CPU when
taking an interrupt. To get this guarantee, we need to perform an
MMIO read from the device, which will flush all outstanding DMAs
from bridges between the device and the system.

df07d6999e drm/radeon: Writeback endian fixes
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.

a0533fbf87 drm/radeon: Remove a bunch of useless _iomem casts
Just defining rdev->rmmio properly in the first place should do
the trick. In some cases, the cast were also complete dups as
the original variable was already of the right type.

ee2762916f DRM: Radeon: Fix section mismatch.
WARNING: drivers/gpu/drm/radeon/radeon.o(.text+0x5d1fc): Section mismatch in reference from the function radeon_get_clock_info() to the function .devinit.text:radeon_read_clocks_OF()
The function radeon_get_clock_info() references
the function __devinit radeon_read_clocks_OF().
This is often because radeon_get_clock_info lacks a __devinit
annotation or the annotation of radeon_read_clocks_OF is wrong.
