Currently, we believe the GPU is idle if just the RENDER ring is idle.
This is obviously wrong if we only using either the BLT or the BSD
rings and so masking genuine hangs.

In the event that we fail to dispatch the execbuffer, for example if
there is insufficient space on the ring, we were leaving the objects in
an inconsistent state. Notably they were marked as being in the GPU
write domain, but were not added to the ring or any list. This would
lead to inevitable oops:

Preparing the ringbuffer for adding new commands can fail (a timeout
whilst waiting for the GPU to catch up and free some space). So check
for any potential error before overwriting HEAD with new commands, and
propagate that error back to the user where possible.

The ringbuffer keeps a pointer to the parent device, so we can use that
instead of passing around the pointer on the stack.

Blitting from vram to gart is problematic at the moment.
Use the CPU for now to avoid buffer corruption.

This patch tries to make sure that the vbl.reply.sequence
vblank count for a queued or emitted vblank event always
corresponds to the true vblank count of queueing/emission, so
the ddx can rely on the returned target_msc for consistency
checks and implementation of swap_intervals in glXSwapBuffers().
Without this there is a small race-condition between the
userspace ddx queueing a vblank event and the vblank
counter incrementing before the event gets queued in
the kernel.

Kconfig says fbcon is required by drm_kms_helper. If radeon, fbcon,
and drm_kms_helper are all modules, radeon is auto loaded (by PCI id?),
drm_kms_helper is loaded because of the module dependency, but fbcon
isn't loaded leaving the console unusable. Since fbcon is required
and there isn't an explicit module dependency, request the module
to be loaded from drm_kms_helper.

Works more like DCE4.0 despite what the docs say.
This fixes blank screen issues when changing crtc
routing due to incorrect crtc to dig mapping.
v2: only two DIGx blocks, routing is hardcoded
based on link.

For the fbdev api if the struct fb_var_screeninfo accel_flags field is set
to FB_ACCELF_TEXT then userland applications can not mmap the mmio region.
Since it is a bad idea for DRM drivers to expose the mmio region via the
fbdev layer we always set the accel_flags to prevent this. Please apply.

The IPS driver is designed to be able to run detached from i915 and
just not enable GPU turbo in that case, in order to avoid module
dependencies between the two drivers. This means that we don't know
what the load order between the two is going to be, and we had
previously only supported IPS after (optionally) i915, but not i915
after IPS. If the wrong order was chosen, you'd get no GPU turbo, and
something like half the possible graphics performance.

On resume, we were attemping to unblank the displays before the
timing and plls had be reprogrammed which led to atom timeouts
waiting for things that are not yet programmed. Re-program
the mode first, then reset the dpms state.
This fixes the infamous atombios timeouts on resume.

Only reset the grbm blocks, srbm tends to lock the GPU
if not done properly and in most cases is not necessary.
Also, no need to call asic init after reset the grbm blocks.

various parts of it, which might frighten babies or cause all sort

If the tail advances beyond the autoreport HEAD value, then we need to
fallback to an uncached read of the HEAD register in order to ascertain
the correct amount of remaining space in the ringbuffer.

The DisplayPort standard (1.1a) states that:
The I2C-over-AUX Reply field is valid only when Native AUX CH Reply
field is AUX_ACK (00). When Native AUX CH Reply field is not 00, then,
I2C-over-AUX Reply field must be 00 and be ignored.
This fixes broken EDID reading when using an active DisplayPort to
duallink DVI converter. If the AUX CH replier chooses to defer the
transaction, a short read occurs and erroneous data is returned as
the i2c reply due to a lack of length checking and failure to check
for AUX ACK.
As a result, broken EDIDs can look like:

The "e" pointer is either NULL or freed when we call

I changed another caller to use "pipe" as well for consistency.

Grub doesn't parse spaces in parameters correctly, so
this makes it impossible to force video= parameters
for kms on the grub kernel command line.

Forbid allocating buffer bigger than visible VRAM or GTT, also
properly set lpfn field.
v2 - use max macro
- silence warning
v3 - don't explicitly set range limit
- use min macro

Prevents code that assumes that the encoder is active when asked to be
disabled from dying a horrible death.

to depend upon an operation that is only valid when the link is still
attached to a pipe.
