Alex Deucher 64912e997f drm/radeon/kms: set HPD polarity in hpd_init()
Polarity needs to be set accordingly to connector status (connected
or disconnected). Set it up in hpd_init() so first hotplug works
reliably no matter what is the initial set of connector. hpd_init()
also covers resume so HPD will work correctly after resume as well.

Alex Deucher a18cee15ed drm/radeon/kms: add MSI module parameter
Allow the user to override whether MSIs are enabled
or not on supported ASICs.  MSIs are disabled by default
on IGP chips as they tend not to work.  However certain
IGP chips only seem to work with MSIs enabled.

I suspect this is a chipset or bios issue, but I'm not sure
what the proper fix is.  This will at least make diagnosing
and working around the problem much easier.

Alex Deucher bc1c4dc390 drm/radeon/kms: always do extended edid probe
Rather than having a quirk list just always check the EDID header
when probing.  This is the recommended behavior according to the
display team.  This avoids problems with improperly terminated
i2c lines on some boards.  This is also what the proprietary
driver does.

Alex Deucher fab249ed97 drm/radeon/kms: remove useless radeon_ddc_dump()
The function didn't work with DP, eDP, or DP bridge
connectors and thus confused users as it lead them to
believe nothing was connected or the EDID was invalid
when in fact is was, just on the aux bus rather an i2c.

It should also speed up module loading as it avoids a
bunch of extra DDC probing.

Since force handling rework of d0d0a225e6
we could end up bouncing connector status btw disconnected and unknown.
When connector status change a call to output_poll_changed happen which
in turn ask again for detect but with force set.

So set the load detect flags whenever we report the connector as
connected or unknown this avoid bouncing btw disconnected and unknown.

Michael Witten c245cb9e15 DRM: bug: RADEON_DEBUGFS_MAX_{NUM_FILES => COMPONENTS}
The value of RADEON_DEBUGFS_MAX_NUM_FILES has been used to
specify the size of an array, each element of which looks
like this:

  struct radeon_debugfs {
          struct drm_info_list    *files;
          unsigned                num_files;
  };

Consequently, the number of debugfs files may be much greater
than RADEON_DEBUGFS_MAX_NUM_FILES, something that the current
code ignores:

  if ((_radeon_debugfs_count + nfiles) > RADEON_DEBUGFS_MAX_NUM_FILES) {
          DRM_ERROR("Reached maximum number of debugfs files.\n");
          DRM_ERROR("Report so we increase RADEON_DEBUGFS_MAX_NUM_FILES.\n");
          return -EINVAL;
  }

This commit fixes this make, and accordingly renames:

  RADEON_DEBUGFS_MAX_NUM_FILES

to:

  RADEON_DEBUGFS_MAX_COMPONENTS

Marek Olšák dfadbbdb57 drm/ttm: add a way to bo_wait for either the last read or last write
Sometimes we want to know whether a buffer is busy and wait for it (bo_wait).
However, sometimes it would be more useful to be able to query whether
a buffer is busy and being either read or written, and wait until it's stopped
being either read or written. The point of this is to be able to avoid
unnecessary waiting, e.g. if a GPU has written something to a buffer and is now
reading that buffer, and a CPU wants to map that buffer for read, it needs to
only wait for the last write. If there were no write, there wouldn't be any
waiting needed.

This, or course, requires user space drivers to send read/write flags
with each relocation (like we have read/write domains in radeon, so we can
actually use those for something useful now).

Now how this patch works:

The read/write flags should passed to ttm_validate_buffer. TTM maintains
separate sync objects of the last read and write for each buffer, in addition
to the sync object of the last use of a buffer. ttm_bo_wait then operates
with one the sync objects.

Jay Estabrook ffb57c4b86 drm/radeon/alpha: Add Alpha support to Radeon DRM code
Alpha needs to have available the system bus address for the Radeon's
local memory, so that it can be used in ttm_bo_vm_fault(), when building
the PTEs for accessing that VRAM.  So, we make bus.addr hold the ioremap()
return, and then we can modify bus.base appropriately for use during page
fault processing.

Alex Deucher 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.

Matthew Garrett bcc65fd8e9 drm/radeon: re-POST the asic on Apple hardware when booted via EFI
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.

Matthew Garrett 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.

Thomas Reim a81b31e9fc drm/radeon: Extended DDC Probing for ECS A740GM-M DVI-D Connector
ECS A740GM-M with ATI RADEON 2100 sends data to i2c bus
   for a DVI connector that is not implemented/existent on the board.

   Fix by applying extented DDC probing for this connector.

   Requires [PATCH] drm/radeon: Extended DDC Probing for Connectors
   with Improperly Wired DDC Lines

   Tested for kernel 2.6.38 on Asus ECS A740GM-M board
