'mappable' isn't really used at all, nor is it necessary anymore as the
bo code is capable of moving buffers to mappable vram as required.
'no_vm' isn't necessary anymore either, any places that don't want to be
mapped into a GPU address space should allocate the VRAM directly instead.

We need to be able to have the bh run while possibly spinning waiting for
the EVO notifier to signal. This apparently happens in some circumstances
with preempt disabled, so our workqueue was never being run.

With cmwq, there's no reason for nouveau to use a dedicated workqueue.
Drop dev_priv->wq and use system_wq instead. Each work item is sync
flushed when the containing structure is unregistered/destroyed.
Note that this change also makes sure that nv50_gpio_handler is not
freed while the contained work item is still running.

We need to track the state of the switch in drivers, so that after s/r
we don't resume the card we've explicitly switched off before. Also
don't allow a userspace open to occur if we've switched the gpu off.

NVC0 will be able to share some of nv50's paths this way. This also makes
it the card-specific vram code responsible for deciding if a given set
of tile_flags is valid, rather than duplicating the allowed types in
nv50_vram.c and nouveau_gem.c

As of this commit, it's guaranteed that if an object is in VRAM that its
GPU virtual address will be constant.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
This is required on nv50 as we need to be able to have more precise control
over physical VRAM allocations to avoid buffer corruption when using
buffers of mixed memory types.
This removes some nasty overallocation/alignment that we were previously
using to "control" this problem.

There have been reports of PFIFO cache errors during context take down
(fdo bug 31637). They are caused by some GPU objects being taken out
while the channel is still potentially processing commands. Make sure
that all the previous rendering has landed before releasing a GPU
object.

Allows callers to install their own handlers for when a GPIO line
changes state (such as for hotplug detect).
This also fixes a bug where we weren't acknowledging the GPIO IRQ
until after the bottom half had run, causing a severe IRQ storm
in some cases.

nouveau_bo_move_m2mf() needs to lock the kernel channel, and it may be
called from the pushbuf IOCTL with an user channel already locked. Use
a separate subclass for the kernel channel mutex because this is
legitimate mutex nesting.

In a multihead setup vblank interrupts may end up enabled in both
heads. In that case we want to ignore the vblank interrupts coming
from the wrong CRTC to avoid tearing and unbalanced calls to
drm_vblank_get/put (fdo bug 31074).

nouveau_fence_* functions are not type safe, which could lead to bugs.
Additionally every use of nouveau_fence_unref had to cast struct
nouveau_fence to void **.
Fix it by renaming old functions and creating static inline functions with
new prototypes. We still need old functions, because we pass function
pointers to ttm.
As we are wrapping functions, drop unused "void *arg" parameter where possible.

Only supported on NV50+ so far, and disabled by default currently. The
module parameter "msi=1" will enable it.
There's a kernel bug which will cause this to fail if the module (or the
NVIDIA binary driver) has ever been loaded before loading nouveau with
MSI enabled. As such, this is only safe to enable if you have nouveau
load on boot, and don't wish to ever reload it.
The workaround is to "echo 0 > /sys/bus/pci/devices/<device>/enable"
until the enable count reads 0. Then you should be able to load nouveau
with MSI enabled.
