Add libdw-based functions for loading and querying debuginfo. Load debuginfo from the system and the linux-user loaders. This is useful for the upcoming perf support, which can then put human-readable guest symbols instead of raw guest PCs into perfmap and jitdump files.

Since these functions have been moved into a new, separate file (kvm_irqcount.c) which is now always compiled and linked if necessary, we can get rid of the #ifdef TARGET_I386 switches in mc146818rtc.c and declare it in the softmmu_ss instead of specific_ss, so that the code only gets compiled once for all targets.

2023-01-13hw/pci/pci: Factor out pci_bus_map_irqs() from pci_bus_irqs()Bernhard Beschow8-15/+25
pci_bus_irqs() coupled together the assignment of pci_set_irq_fn and pci_map_irq_fn to a PCI bus. This coupling gets in the way when the pci_map_irq_fn is board-specific while the pci_set_irq_fn is device- specific. For example, both of QEMU's PIIX south bridge models have different pci_map_irq_fn implementations which are board-specific rather than device-specific. These implementations should therefore reside in board code. The pci_set_irq_fn's, however, should stay in the device models because they access memory internal to the model. Factoring out pci_bus_map_irqs() from pci_bus_irqs() allows the assignments to be decoupled, resolving the problem described above. Note also how pci_vpb_realize() which gets touched in this commit assigns different pci_map_irq_fn's depending on the board.

2023-01-13hw/mips/malta: Set PIIX4 IRQ routes in embedded bootloaderPhilippe Mathieu-Daudé1-0/+18
Linux kernel expects the northbridge & southbridge chipsets configured by the BIOS firmware. We emulate that by writing a tiny bootloader code in write_bootloader(). Upon introduction in commit 5c2b87e34d ("PIIX4 support"), the PIIX4 configuration space included values specific to the Malta board. Set the Malta-specific IRQ routing values in the embedded bootloader, so the next commit can remove the Malta specific bits from the PIIX4 PCI-ISA bridge and make it generic (matching the real hardware).

2023-01-13hw/mips/malta: Introduce PIIX4_PCI_DEVFN definitionPhilippe Mathieu-Daudé1-1/+3
The PIIX4 PCI-ISA bridge function is always located at 10:0. Since we want to re-use its address, add the PIIX4_PCI_DEVFN definition.
