When max_bytes is not 8 bytes aligned and bo size is larger than
max_bytes, the last 8 bytes in a ttm node may be left unchanged.
For example, on pre SDMA 4.0, max_bytes = 0x1fffff, and the bo size

In order to fix the problem, we separately store the max nums of

Currently, amdgpu driver doesn't disable pci device when removing
driver, the enable_cnt of pci device will not be decrease to 0.
When reloading driver, pci_enable_device will do nothing as

So current_state of pci device is not D0 state and pci_enable_msi

drm/amd: Closed hash table with low overhead (v2)

This adds a statically sized closed hash table implementation with
low memory and CPU overhead. The API is inspired by kfifo.

Storing, retrieving and deleting data does not involve any dynamic
memory management, which makes it ideal for use in interrupt context.
Static memory usage per entry comprises a 32 or 64 bit hash key, two
bits for occupancy tracking and the value size stored in the table.
No list heads or pointers are needed. Therefore this data structure
should be quite cache-friendly, too.

It uses linear probing and lazy deletion. During lookups free space
is reclaimed and entries relocated to speed up future lookups.

drm/amdgpu: Add PASID management

Allows assigning a PASID to a VM for identifying VMs involved in page
faults. The global PASID manager is also exported in the KFD
interface so that AMDGPU and KFD can share the PASID space.

PASIDs of different sizes can be requested. On APUs, the PASID size
is deterined by the capabilities of the IOMMU. So KFD must be able
to allocate PASIDs in a smaller range.

drm/radeon: properly initialize r600_audio_status() data

The structure returned from r600_audio_status() is only partially
initialized, and older gcc versions (4.3 and 4.4) warn about this:

drivers/gpu/drm/radeon/r600_hdmi.c: In function 'r600_audio_status':
drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.id' is used uninitialized in this function
drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.connected' is used uninitialized in this function
drivers/gpu/drm/radeon/r600_hdmi.c:108: error: 'status.offset' is used uninitialized in this function

This is harmless and surprisingly correct in C99, as the caller
only accesses the fields that got initialized, so newer compilers
don't warn about it, but initializing the entire structure feels
like the right thing to do here and avoids the warning.
