IH tracks pending retry faults in a hash table for fast lookup in interrupt context. Each VM has a short FIFO of pending VM faults for processing in a bottom half. The IH prescreening stage adds retry faults and filters out repeated retry interrupts to minimize the impact of interrupt storms. It's the VM's responsibility remove pending faults once they are handled. For now this is only done when the VM is destroyed. v2: - Made the hash table smaller and the FIFO longer. I never want the FIFO to fill up, because that would make prescreen take longer. 128 pending page faults should be enough to keep migrations busy. Signed-off-by:

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. v2: squash in do_div and _BITOPS_LONG_SHIFT fixes Signed-off-by:

Felix Kuehling authored
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. Signed-off-by:

currently, for CI asics, use dpm by default, amdgpu.dpm=-1. when set amdgpu.dpm=1, enable powplay. when set amdgpu.dpm=0, disable both dpm and powerplay. when powerplay is stable on CI asics, ci_dpm will be removed. Reviewed-by:

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.
