drm/radeon: disable MSI on RV515
My rv515 card is very flaky with msi enabled. Every so often it loses a rearm
and never comes back, manually banging the rearm brings it back.

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.

drm/radeon: use system_wq instead of dev_priv->wq
With cmwq, there's no reason for radeon to use a dedicated workqueue.
Drop dev_priv->wq and use system_wq instead.
Because radeon_driver_irq_uninstall_kms() may be called from
unsleepable context, the work items can't be flushed from there.
Instead, init and flush from radeon_irq_kms_init/fini().
While at it, simplify canceling/flushing of rdev->pm.dynpm_idle_work.
Always initialize and sync cancel instead of being unnecessarily smart
about it.

output the user might plug in later, we only have hotplug detect
from the digital outputs. So if we detect no connected outputs at

drm/fb: fix fbdev object model + cleanup properly.
The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work.
This patch
a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs.
b) migrated all the fb helper functions out of the crtc helper file into the fb helper file.
c) pushed the fb probing/hotplug control into the driver
d) makes the surface sizes into a structure for ease of passing
This changes the intel/radeon/nouveau drivers to use the new helper.

PCI quirk: RS780/RS880: work around missing MSI initialization
AMD says in section 2.5.4 (GFX MSI Enable) of #43291 (AMD 780G Family
Register Programming Requirements):
The SBIOS must enable internal graphics MSI capability in GCCFG by
setting the following: NBCFG.NB_CNTL.STRAP_MSI_ENABLE='1'
Quite a few BIOS writers misinterpret this sentence and think that
enabling MSI is an optional feature. However, clearing that bit just
prevents delivery of MSI messages but does not remove the MSI PCI
capabilities registers, and so leaves these devices unusable for any
driver that attempts to use MSI.
Setting that bit is not possible after the BIOS has locked down the
configuration registers, so we have to manually disable MSI for the
affected devices.
This fixes the codec communication errors in the HDA driver when
accessing the HDMI audio device, and allows us to get rid of the
overcautious quirk in radeon_irq_kms.c.

drm/radeon/kms: Add support for interrupts on r6xx/r7xx chips (v3)
This enables the use of interrupts on r6xx/r7xx hardware.
Interrupts are implemented via a ring buffer. The GPU adds
interrupts vectors to the ring and the host reads them off
in the interrupt handler. The interrupt controller requires
firmware like the CP. This firmware must be installed and
accessble to the firmware loader for interrupts to function.
MSIs don't seem to work on my RS780. They work fine on all
my discrete cards. I'm not sure about other RS780s or
RS880s. I've disabled MSIs on RS780 and RS880, but it would
probably be worth checking on some other systems.
v2 - fix some checkpatch.pl problems;
re-read the disp int status reg if we restart the ih;
v3 - remove the irq handler if r600_irq_init() fails;
remove spinlock in r600_ih_ring_fini();
move ih rb overflow check to r600_get_ih_wptr();
move irq ack to separate function;

drm/radeon: introduce kernel modesetting for radeon hardware
Add kernel modesetting support to radeon driver, use the ttm memory
manager to manage memory and DRM/GEM to provide userspace API.
In order to avoid backward compatibility issue and to allow clean
design and code the radeon kernel modesetting use different code path
than old radeon/drm driver.
When kernel modesetting is enabled the IOCTL of radeon/drm
driver are considered as invalid and an error message is printed
in the log and they return failure.
KMS enabled userspace will use new API to talk with the radeon/drm
driver. The new API provide functions to create/destroy/share/mmap
buffer object which are then managed by the kernel memory manager
(here TTM). In order to submit command to the GPU the userspace
provide a buffer holding the command stream, along this buffer
userspace have to provide a list of buffer object used by the
command stream. The kernel radeon driver will then place buffer
in GPU accessible memory and will update command stream to reflect
the position of the different buffers.
The kernel will also perform security check on command stream
provided by the user, we want to catch and forbid any illegal use
of the GPU such as DMA into random system memory or into memory
not owned by the process supplying the command stream. This part
of the code is still incomplete and this why we propose that patch
as a staging driver addition, future security might forbid current
experimental userspace to run.
This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX
(radeon up to X1950). Works is underway to provide support for R6XX,
R7XX and newer hardware (radeon from HD2XXX to HD4XXX).
