hw/alpha: Provide a PCI-ISA bridge device node

2021-06-28T14:27:32+00:00

- 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.

hw/alpha: Set minimum PCI device ID to 1 to match Clipper IRQ mappings

2021-06-28T14:27:32+00:00

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.

alpha/dp264: use memdev for RAM

2020-02-19T16:49:54+00:00

memory_region_allocate_system_memory() API is going away, so replace it with memdev allocated MemoryRegion. The later is initialized by generic code, so board only needs to opt in to memdev scheme by providing MachineClass::default_ram_id and using MachineState::ram instead of manually initializing RAM memory region.

hw: replace hw/i386/pc.h with a header just for the i8259

2019-12-17T18:33:49+00:00

Remove the need to include i386/pc.h to get to the i8259 functions. This is enough to remove the inclusion of hw/i386/pc.h from all non-x86 files. Signed-off-by: Paolo Bonzini

Include hw/irq.h a lot less

2019-08-16T11:31:52+00:00

In my "build everything" tree, changing hw/irq.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/hw.h supposedly includes it for convenience. Several other headers include it just to get qemu_irq and.or qemu_irq_handler. Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to qemu/typedefs.h, and then include hw/irq.h only where it's still needed. Touching it now recompiles only some 500 objects.

Move target-* CPU file into a target/ folder

2016-12-20T20:52:12+00:00

We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

Clean up header guards that don't match their file name

2016-07-12T14:19:16+00:00

Header guard symbols should match their file name to make guard collisions less likely. Offenders found with scripts/clean-header-guards.pl -vn. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones. Signed-off-by: Markus Armbruster Reviewed-by: Richard Henderson

hw/alpha: Don't machine check on missing pci i/o

Not really correct, but we don't implement all of the random devices that the kernel looks for. This is good enough to keep us booting. Signed-off-by: Richard Henderson
