Emulate read errors in the DMA Checksum Register for high frequencies and optimistic settings of the Read Timing Compensation Register. This will help in tuning the SPI timing calibration algorithm. Errors are only injected when the property "inject_failure" is set to true as suggested by Philippe. The values below are those to expect from the first flash device of the FMC controller of a palmetto-bmc machine.

The FMC controller on the Aspeed SoCs support DMA to access the flash modules. It can operate in a normal mode, to copy to or from the flash module mapping window, or in a checksum calculation mode, to evaluate the best clock settings for reads. The model introduces two custom address spaces for DMAs: one for the AHB window of the FMC flash devices and one for the DRAM. The latter is populated using a "dram" link set from the machine with the RAM container region.

GPIO pins are arranged in groups of 8 pins labeled A,B,..,Y,Z,AA,AB,AC. (Note that the ast2400 controller only goes up to group AB). A set has four groups (except set AC which only has one) and is referred to by the groups it is composed of (eg ABCD,EFGH,...,YZAAAB). Each set is accessed and controlled by a bank of 14 registers. These registers operate on a per pin level where each bit in the register corresponds to a pin, except for the command source registers. The command source registers operate on a per group level where bits 24, 16, 8 and 0 correspond to each group in the set. eg. registers for set ABCD: |D7...D0|C7...C0|B7...B0|A7...A0| <- GPIOs |31...24|23...16|15....8|7.....0| <- bit position Note that there are a couple of groups that only have 4 pins. There are two ways that this model deviates from the behaviour of the actual controller: (1) The only control source driving the GPIO pins in the model is the ARM model (as there currently aren't models for the LPC or Coprocessor). (2) None of the registers in the model are reset tolerant (needs integration with the watchdog).

handle_alloc() tries to find as many contiguous clusters that need copy-on-write as possible in order to allocate all of them at the same time. However, compressed clusters are only overwritten one by one, so let's say that we have an image with 1024 consecutive compressed clusters: qemu-img create -f qcow2 hd.qcow2 64M for f in `seq 0 64 65472`; do qemu-io -c "write -c ${f}k 64k" hd.qcow2 done In this case trying to overwrite the whole image with one large write request results in 1024 separate allocations: qemu-io -c "write 0 64M" hd.qcow2 This restriction comes from commit 095a9c58 from 2008. Nowadays QEMU can overwrite multiple compressed clusters just fine, and in fact it already does: as long as the first cluster that handle_alloc() finds is not compressed, all other compressed clusters in the same batch will be overwritten in one go: qemu-img create -f qcow2 hd.qcow2 64M qemu-io -c "write -z 0 64k" hd.qcow2 for f in `seq 64 64 65472`; do qemu-io -c "write -c ${f}k 64k" hd.qcow2 done Compared to the previous one, overwriting this image on my computer goes from 8.35s down to 230ms.

The 'blockdev-create' QMP command was introduced as experimental feature in commit b0292b85, using the assert() debug call. It got promoted to 'stable' command in 3fb588a0, but the assert call was not removed. Some block drivers are optional, and bdrv_find_format() might return a NULL value, triggering the assertion. Stable code is not expected to abort, so return an error instead.

Commit 78dd48df removed the last caller of register_savevm_live for an instantiable device (rather than a single system wide device); so trim out the parameter.

Commit 78dd48df reworked vmxnet3's live migration but left a straggling unregister_savevm call. Remove it, although it doesn't seem to have any bad effect.

During migration, there are several places to iterate on savevm.handlers. And on each iteration, we need to check its ops and related callbacks before invoke it. Generally, ops is the first element to check, and it is only necessary to check it once. This patch clean all the related part in savevm.c to check ops only once in those iterations.

When encounter error, multifd_send_thread should always notify who pay attention to it before exit. Otherwise it may block migration_thread at multifd_send_sync_main forever.

The ordering of events that are emitted during the rmdir test have changed with kernel >= 5.3. Semantically both new & old orderings are correct, so we must be able to cope with either. To cope with this, when we see an unexpected event, we push it back onto the queue and look and the subsequent event to see if that matches instead.
