2025-06-19hw/loongarch/virt: Add kernel irqchip supportBibo Mao1-24/+33
If kvm_irqchip_in_kernel() return true, interrupt controller ExtIOI, IPI, PCH_PCI and PCH_MSI should be emlated in kernel. And it is not necessary to create memory region for these devices in user space.

2025-03-20target/loongarch: Clean up virt_cpu_irq_init() error handlingBibo Mao1-3/+4
The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. virt_cpu_irq_init() is wrong that way: it passes &err to hotplug_handler_plug() twice. If both calls failed, this could trip error_setv()'s assertion. Moreover, if just one fails, the Error object leaks. Fortunately, these calls can't actually fail. Messed up in commit 50ebc3fc47f7 (hw/intc/loongarch_ipi: Notify ipi object when cpu is plugged) and commit 087a23a87c57 (hw/intc/loongarch_extioi: Use cpu plug notification).

2024-10-16hw/loongarch/virt: Add FDT table support with acpi ged pm registerBibo Mao1-0/+39
ACPI ged is used for power management on LoongArch virt platform, in general it is parsed from acpi table. However if system boot directly from elf kernel, no UEFI bios is provided and acpi table cannot be used also. Here acpi ged pm register is exposed with FDT table, it is compatbile with syscon method in FDT table, only that acpi ged pm register is accessed with 8-bit mode, rather with 32-bit mode.

2024-10-03hw/char: Extract serial-mmBernhard Beschow1-1/+1
hw/char/serial currently contains the implementation of both TYPE_SERIAL and TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's move the latter into its own module which makes the dependencies more obvious and the code more tidy. The includes and the dependencies have been converted mechanically except in the hw/char directories which were updated manually. The result was compile-tested. Now, only hw/char makes direct use of TYPE_SERIAL: # grep -r -e "select SERIAL" | grep -v SERIAL_ hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL # grep -r -e "/serial\\.h" include/hw/char/serial-mm.h:#include "hw/char/serial.h" hw/char/serial-pci-multi.c:#include "hw/char/serial.h" hw/char/serial.c:#include "hw/char/serial.h" hw/char/serial-isa.c:#include "hw/char/serial.h" hw/char/serial-pci.c:#include "hw/char/serial.h" Tested-by: Andrew Jeffery <andrew@codeconstruct.com.au> Reviewed-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Bernhard Beschow <shentey@gmail.com> Link: https://lore.kernel.org/r/20240905073832.16222-4-shentey@gmail.com Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2024-09-12hw/loongarch: virt: pass random seed to fdtJason A. Donenfeld1-0/+6
If the FDT contains /chosen/rng-seed, then the Linux RNG will use it to initialize early. Set this using the usual guest random number generation function. This is the same procedure that's done in b91b6b5a2c ("hw/microblaze: pass random seed to fdt"), e4b4f0b71c ("hw/riscv: virt: pass random seed to fdt"), c6fe3e6b4c ("hw/openrisc: virt: pass random seed to fdt"), 67f7e426e5 ("hw/i386: pass RNG seed via setup_data entry"), c287941a4d ("hw/rx: pass random seed to fdt"), 5e19cc68fb ("hw/mips: boston: pass random seed to fdt"), 6b23a67916 ("hw/nios2: virt: pass random seed to fdt") c4b075318e ("hw/ppc: pass random seed to fdt"), and 5242876f37 ("hw/arm/virt: dt: add rng-seed property"). These earlier commits later were amended to rerandomize the RNG seed on snapshot load, but the LoongArch code somehow already does that, despite not having this patch here, presumably due to some lucky copy and pasting.
