2022-11-02T10:56:32+00:00

cryptodev: Added a new type of backend named lkcf-backend for cryptodev. This backend upload asymmetric keys to linux kernel, and let kernel do the accelerations if possible.

device-tree: add re-randomization helper function

2022-10-27T10:34:31+00:00

When the system reboots, the rng-seed that the FDT has should be re-randomized, so that the new boot gets a new seed. Several architectures require this functionality, so export a function for injecting a new seed into the given FDT. Cc: Alistair Francis Cc: David Gibson Signed-off-by: Jason A.

reset: allow registering handlers that aren't called by snapshot loading

Snapshot loading only expects to call deterministic handlers, not non-deterministic ones. So introduce a way of registering handlers that won't be called when reseting for snapshots.

hostmem: Allow for specifying a ThreadContext for preallocation

2022-10-27T09:01:03+00:00

Let's allow for specifying a thread context via the "prealloc-context" property. When set, preallcoation threads will be crated via the thread context -- inheriting the same CPU affinity as the thread context. Pinning preallcoation threads to CPUs can heavily increase performance in NUMA setups, because, preallocation from a CPU close to the target NUMA node(s) is faster then preallocation from a CPU further remote, simply because of memory bandwidth for initializing memory with zeroes. This is especially relevant for very large VMs backed by huge/gigantic pages, whereby preallocation is mandatory.

block: add BlockRAMRegistrar

2022-10-26T18:56:42+00:00

Emulated devices and other BlockBackend users wishing to take advantage of blk_register_buf() all have the same repetitive job: register RAMBlocks with the BlockBackend using RAMBlockNotifier. Add a BlockRAMRegistrar API to do this. A later commit will use this from hw/block/virtio-blk.c.

block: return errors from bdrv_register_buf()

2022-10-26T18:56:42+00:00

Registering an I/O buffer is only a performance optimization hint but it is still necessary to return errors when it fails. Later patches will need to detect errors when registering buffers but an immediate advantage is that error_report() calls are no longer needed in block driver .bdrv_register_buf() functions.

block: pass size to bdrv_unregister_buf()

2022-10-26T18:56:42+00:00

The only implementor of bdrv_register_buf() is block/nvme.c, where the size is not needed when unregistering a buffer. This is because util/vfio-helpers.c can look up mappings by address. Future block drivers that implement bdrv_register_buf() may not be able to do their job given only the buffer address. Add a size argument to bdrv_unregister_buf(). Also document the assumptions about bdrv_register_buf()/bdrv_unregister_buf() calls. The same values that were given to bdrv_register_buf() must be given to bdrv_unregister_buf(). gcc 11.2.1 emits a spurious warning that img_bench()'s buf_size local variable might be uninitialized, so it's necessary to silence the compiler.
