There might be issue with lockup detection when scheduling on an
empty ring that have been sitting idle for a while. Thus update
the lockup tracking data when scheduling new work in an empty ring.

This fixes the kernel side so that the ring should come
up and ring and IB tests should work. The userspace
UVD drivers will also need big endian fixes.

UVD ring can't use scratch thus it does need writeback buffer to keep
a valid address or radeon_ring_backup will trigger a kernel fault.
It's ok to not unpin the write back buffer on suspend as it leave in
gtt and thus does not need eviction.

If a buffer is never bound to a virtual memory pagetable than don't try
to unbind it. Only drawback is that we don't update the pagetable when
unbinding the ib pool buffer which is fine because it only happens at
suspend or module unload/shutdown.
Fixes spurious messages about buffers without VM mappings. E.g.:
radeon 0000:01:00.0: bo ffff88020afac400 don't has a mapping in vm ffff88021ca2b900

The current radeon driver initialization routines, when using KMS, are written
so that the IRQ installation routine is called before initializing the WB buffer
and the CP rings. With some ASICs, though, the IRQ routine tries to access the
GFX_INDEX ring causing a call to RREG32 with the value of -1 in
radeon_fence_read. This, in turn causes the system to completely hang with some
cards, requiring a hard reset.
A call stack that can cause such a hang looks like this (using rv515 ASIC for the
example here):
* rv515_init (rv515.c)
* radeon_irq_kms_init (radeon_irq_kms.c)
* drm_irq_install (drm_irq.c)
* radeon_driver_irq_preinstall_kms (radeon_irq_kms.c)
* rs600_irq_process (rs600.c)
* radeon_fence_process - due to SW interrupt (radeon_fence.c)
* radeon_fence_read (radeon_fence.c)
* hang due to RREG32(-1)
The patch moves the IRQ installation to the card startup routine, after the ring
has been initialized, but before the IRQ has been set. This fixes the issue, but
requires a check to see if the IRQ is already installed, as is the case in the
system resume codepath.
I have tested the patch on three machines using the rv515, the rv770 and the
evergreen ASIC. They worked without issues.
This seems to be a known issue and has been reported on several bug tracking
sites by various distributions (see links below). Most of reports recommend
booting the system with KMS disabled and then enabling KMS by reloading the
radeon module. For some reason, this was indeed a usable workaround, however,
UMS is now deprecated and disabled by default.

radeon currently uses a drm function to get the speed capabilities for
the bus, drm_pcie_get_speed_cap_mask. However, this is a non-standard
method of performing this detection and this patch changes it to use
the max_bus_speed attribute.

This narrows the scope of the apple re-POST hack added in:
drm/radeon: re-POST the asic on Apple hardware when booted via EFI
That patch prevents UVD from working on macs when booted in EFI
mode. The original patch fixed macbook2,1 systems which were
r5xx and hence have no UVD. Limit the hack to those systems to
prevent UVD breakage on newer systems.

Newer asics have variable numbers of crtcs. Use that
rather than the asic family to determine which crtcs
to check. This avoids checking non-existent crtcs or
missing crtcs on certain asics.

When UMS was deprecated it removed support for nomodeset commandline
we really want this in distro land so we can debug stuff, everyone

v2: oops -1 isn't used anymore, restore original behaviour
-1 is default, so we can boot with nomodeset on the command line,
then use radeon.modeset=1 to override it for debugging later.
