Add a AMDGPU_GEM_CREATE_DISCARDABLE flag to note that the content of a BO
doesn't needs to be preserved during eviction.
KFD was already using a similar functionality for SVM BOs so replace the
internal flag with the new UAPI.

Add a new CTX ioctl operation to set stable pstates for profiling.
When creating traces for tools like RGP or using SPM or doing
performance profiling, it's required to enable a special
stable profiling power state on the GPU. These profiling
states set fixed clocks and disable certain other power
features like powergating which may impact the results.
Historically, these profiling pstates were enabled via sysfs,
but this adds an interface to enable it via the CTX ioctl
from the application. Since the power state is global
only one application can set it at a time, so if multiple
applications try and use it only the first will get it,
the ioctl will return -EBUSY for others. The sysfs interface
will override whatever has been set by this interface.

- Add interface to load SRIOV cap FW. If the FW does not
exist, simply skip this FW loading routine.
This FW will only be loaded under SRIOV. Other driver
configuration will not be affected.
By adding this interface, it will make us easier to
prepare SRIOV Linux guest driver for different users.
- Update sysfs interface to read cap FW version.
- Refactor PSP FW loading routine under SRIOV to use a
unified SWITCH statement instead of using IF statement
- Remove redundant amdgpu_sriov_vf() check in FW loading
routine

Add AMDGPU_INFO_VBIOS_INFO subquery id for detailed vbios info.
Provides a way for the user application to get the VBIOS
information without having to parse the binary.
It is useful for the user to be able to display in a simple way the VBIOS
version in their system if they happen to encounter an issue.
V2:
Use numeric serial.
Parse and expose vbios version string.
V3:
Remove redundant data in drm_amdgpu_info_vbios struct.
V4:

SG BOs such as dmabuf imports and userptr BOs do not consume system
resources directly. Instead they point to resources owned elsewhere.
They typically get evicted by DMABuf move notifiers of MMU notifiers.
If those notifiers don't need to wait for hardware fences (i.e. the SG
BOs are used in a preemptible context), then we don't need to limit
them to the GTT size and we don't need TTM to evict them.
Create a new placement for such preemptible SG BOs that does not impose
artificial size limits and TTM evictions.

Given a master fd we can then override the priority of the context
in another fd.
Using these overrides was recommended by Christian instead of trying
to submit from a master fd, and I am adding a way to override a
single context instead of the entire process so we can only upgrade
a single Vulkan queue and not effectively the entire process.
Reused the flags field as it was checked to be 0 anyways, so nothing
used it. This is source-incompatible (due to the name change), but
ABI compatible.

[Why]
Hardware support for Delta Color Compression (DCC) decompression is
available in DC for GFX9 but there's no way for userspace to enable
the feature.
Enabling the feature can provide improved GFX performance and
power savings in many situations.
[How]
Extend the GFX9 tiling flags to include DCC parameters. These are
logically grouped together with tiling flags even if they are
technically distinct.
This trivially maintains backwards compatibility with existing
users of amdgpu_gem_metadata. No new IOCTls or data structures are
needed to support DCC.
This patch helps expose DCC attributes to both libdrm and amdgpu_dm.

This change is to support MESA performace optimization.

buffer handles to create a temporay bo list and then destroy it
when IOCTL completes.
This saves on calling for BO_LIST create and destry IOCTLs in MESA
and by this improves performance.
