Keep the cdclk maximum supported frequency around in dev_priv so that we
can verify certain things against it before actually changing the cdclk
frequency.

For now only VLV/CHV have support changing cdclk frequency, so other

Linux 4.1-rc6

backmerge 4.1-rc6 as some of the later pull reqs are based on newer bases
and I'd prefer to do the fixup myself.

This fixes some regressions in i915 when converting to atomic.
set_config failed with -EINVAL, and I received the following warning
in dmesg:

[drm:drm_atomic_crtc_check] [CRTC:20] active without enabled

Solve this by clearing active when a crtc is disabled.

Because crtc_state->enable implies that connectors are active the
change from disabled->enabled can only happen for the crtc that's
being set_config'd, and checking for !crtc_state->enable is sufficient
here.

One more round of drm-misc, again mostly atomic. Big thing is the
userspace blob code from Daniel Stone, with support for the mode_id blob
now added to the atomic ioctl. Finally we can do atomic modesets!

Note that the atomic ioctl is still behind the module knob since the
weston patches aren't quite ready yet imo - they lack TEST_ONLY support,
which is a fairly crucial bit of the atomic api. But besides that I think
it's all good to go. That's also why we didn't bother to hide the new blob
ioctls behind the knob, that part won't need to change. And if weston
patches get in shape in time we could throw the "atomic by default patch"
on top for 4.2.

drm-amdkfd-next-2015-06-03:

- Add the H/W debugger support module, including new IOCTLs to:
  - register/unregister a process as a debugged process
  - Set address watch-point in the debugged process's GPU kernel
  - Do a wave control operation in the debugged process's waves
  See the commit messages for more details on the available operations.

  The debugged process can only perform debug operation on itself. It is
  blocked by the amdkfd+H/W from performing operations on other processes's
  waves or GPU kernels. The blocking is done by setting the VMID and PASID of
  the debugged process in the packets that are sent to the CP with the debug
  instructions.

- Add support for static user-mode queues. These queues are regular queues,
  but because they belong to the debugged process, we need to make sure the CP
  doesn't preempt them during a debug operation. Therefore, we mark them as
  static for the CP ignore them during preemption.

- Support killing all the waves when a process is terminated. This is needed
  in case a process is terminated but we can't UNMAP its queues (can occur due
  to several reasons). In that case, the CP could be stuck unless we kill all
  its waves. This function is *very* important as it provides the kernel a high
  level of control over the GPU. The reason we didn't upstream this function
  so far, is because it is implemented using the H/W debugger module functions,
  so we had to wait until we can upstream the H/W debugger module.

- Replace declaration of bitmap from unsigned long to standard DECLARE_BITMAP

This patch adds a kms driver for the virtio gpu.  The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.

Qemu patches for the host side are under review currently.

The pci version of the device comes in two variants: with and without
vga compatibility.  The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device.  The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.

Initial revision has only 2d support, 3d (virgl) support requires
some more work on the qemu side and will be added later.

Queues which are designated as static can NOT be preempted by

This patch adds four new IOCTLs to amdkfd. These IOCTLs expose a H/W
debugger functionality to the userspace.

The IOCTLs are:

- AMDKFD_IOC_DBG_REGISTER:

The purpose of this IOCTL is to notify amdkfd that a process wants to use
GPU debugging facilities on itself only.
It is expected that this IOCTL would be called before any other H/W
debugger requests are sent to amdkfd and for each GPU where the H/W
debugging needs to be enabled. The use of this IOCTL ensures that only
one instance of a debugger is active in the system.

- AMDKFD_IOC_DBG_UNREGISTER:

This IOCTL detaches the debugger/debugged process from the H/W
Debug which was established by the AMDKFD_IOC_DBG_REGISTER IOCTL.

- AMDKFD_IOC_DBG_ADDRESS_WATCH:

This IOCTL allows to set different watchpoints with various conditions as
indicated by the IOCTL's arguments. The available number of watchpoints
is retrieved from topology. This operation is confined to the current
debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER.

- AMDKFD_IOC_DBG_WAVE_CONTROL:

This IOCTL allows to control a wavefront as indicated by the IOCTL's
arguments. For example, you can halt/resume or kill either a
single wavefront or a set of wavefronts. This operation is confined to
the current debugged process, which was registered through
AMDKFD_IOC_DBG_REGISTER.

Because the arguments for the address watch IOCTL and wave control IOCTL
are dynamic, meaning that they could vary in size, the userspace passes a
pointer to a structure (in userspace) that contains the value of the
arguments. The kernel driver is responsible to parse this structure and
validate its contents.
