2021-06-28hw/alpha: Provide a PCI-ISA bridge device nodeJason Thorpe4-27/+36
- Move initialization of the ISA bus from typhoon_init() to clipper_init(); this apsect of device topology is really associated with the individual model, not the core logic chipset. typhoon_init() now returns the IRQ to use for the output of the ISA PIC. - In clipper_init(), instantiate an i82378 instance, and connect its PIC output to the ISA IRQ input provided by typhoon_init(). Remove the explicit instantiations of i8254 and i82374, as these devices are subsumed by the i82378.

2021-06-28hw/alpha: Set minimum PCI device ID to 1 to match Clipper IRQ mappingsJason Thorpe3-5/+9
Since we are emulating a Clipper device topology, we need to set the minimum PCI device ID to 1, as there is no IRQ mapping for a device at ID 0 (see sys_dp264.c:clipper_map_irq()). - Add a 'devfn_min' argument to typhoon_init(). Pass that argument along to pci_register_root_bus(). - In clipper_init(), pass PCI_DEVFN(1, 0) as the minimum PCI device ID/function.

2021-06-25block-copy: atomic .cancelled and .finished fields in BlockCopyCallStateEmanuele Giuseppe Esposito2-15/+24
By adding acquire/release pairs, we ensure that .ret and .error_is_read fields are written by block_copy_dirty_clusters before .finished is true, and that they are read by API user after .finished is true. The atomic here are necessary because the fields are concurrently modified in coroutines, and read outside.

2021-06-25block-copy: add CoMutex lockEmanuele Giuseppe Esposito1-39/+116
Group various structures fields, to better understand what we need to protect with a lock and what doesn't need it. Then, add a CoMutex to protect concurrent access of block-copy data structures. This mutex also protects .copy_bitmap, because its thread-safe API does not prevent it from assigning two tasks to the same bitmap region. Exceptions to the lock: - .sleep_state is handled in the series "coroutine: new sleep/wake API" and thus here left as TODO. - .finished, .cancelled and reads to .ret and .error_is_read will be protected in the following patch, because are used also outside coroutines. - .skip_unallocated is atomic. Including it under the mutex would increase the critical sections and make them also much more complex. We can have it as atomic since it is only written from outside and read by block-copy coroutines.

2021-06-25block-copy: streamline choice of copy_range vs. read/writePaolo Bonzini1-86/+90
Put the logic to determine the copy size in a separate function, so that there is a simple state machine for the possible methods of copying data from one BlockDriverState to the other. Use .method instead of .copy_range as in-out argument, and include also .zeroes as an additional copy method. While at it, store the common computation of block_copy_max_transfer into a new field of BlockCopyState, and make sure that we always obey max_transfer; that's more efficient even for the COPY_RANGE_READ_WRITE case.

2021-06-25progressmeter: protect with a mutexEmanuele Giuseppe Esposito7-28/+124
Progressmeter is protected by the AioContext mutex, which is taken by the block jobs and their caller (like blockdev). We would like to remove the dependency of block layer code on the AioContext mutex, since most drivers and the core I/O code are already not relying on it. Create a new C file to implement the ProgressMeter API, but keep the struct as public, to avoid forcing allocation on the heap. Also add a mutex to be able to provide an accurate snapshot of the progress values to the caller.
