Testing on a Polaris11 gpu with DCE-11.2 suggests that it
seems to work fine there, so optimistically enable it for
DCE-11 and later.

Expose support for DRM_FORMAT_ABGR16161616F and
DRM_FORMAT_XBGR16161616F to the DRM core, complementing
the already existing xRGB ordered fp16 formats.
These are especially useful for creating presentable
swapchains in Vulkan for VK_FORMAT_R16G16B16A16_SFLOAT.

Hi,
two patches. The first one adds the xBGR ordered variants of fp16
in addition to the xRGB ordered variants that were merged just
very recently.
These variants are required for direct scanout of OpenGL and Vulkan
rendered content, as both OpenGL (GL_RGBA16F) and Vulkan

Track SDMA usage on a per process basis and report it through sysfs.
The value in the sysfs file indicates the amount of time SDMA has
been in-use by this process since the creation of the process.
This value is in microsecond granularity.

[WHY & HOW]
There is a problem in hscale_pixel_rate, the bug
causes DCN to be more optimistic (more likely to underflow)
in upscale cases during prefetch.
This commit ports the fix from DV code to address these issues.

Hi, Jiange,
How to handle the case that multi-apps do the auto dump? This patch seems
not multi-process safety.

When GPU got timeout, it would notify an interested part
of an opportunity to dump info before actual GPU reset.
A usermode app would open 'autodump' node under debugfs system

Hi Jiange,
it probably won't hurt, but I would just drop that. You need roughly 4
billion GPU resets until the UINT_MAX-1 becomes zero again.

Hi Christian,
wait_for_completion_interruptible_timeout() would decrease
autodump.dumping.done to UINT_MAX-1.
complete_all() here would restore autodump.dumping to the state as in
amdgpu_debugfs_autodump_init().
