d9237edbb5 hw/acpi/Kconfig: Do not needlessly build TYPE_PIIX4_PM in non-PC/Malta machines
TYPE_PIIX4_PM is only used in machines where PIIX chipsets are used
which is currently PC and Malta. There is no point building it for the
other ACPI_X86 machines.

Note that this also removes unneeded ACPI_PIIX4 from PEGASOS2.

66baa500c9 hw/acpi/Kconfig: Add missing dependencies to ACPI_ICH9
ich9_lpc_realize() uses apm_init() and ich9_smbus_realize() uses
pm_smbus_init(), so both APM and ACPI_SMBUS are provided by the device
models managed by ACPI_ICH9.

a913901644 hw/acpi/Kconfig: Rename ACPI_X86_ICH to ACPI_ICH9
Although the ICH9 ACPI controller may currently be tied to x86 it
doesn't have to. Furthermore, the source files this configuration switch
manages contain a '9', so this name fits more.

hw/intc/loongarch_pch: Change default irq number of pch irq controller
Change the default irq number of pch pic to 32, so that the irq
number of pch msi is 224(256 - 32), and move the 'PCH_PIC_IRQ_NUM'
macro to pci-host/ls7a.h and add prefix 'VIRT' on it to keep standard

for loongarch_pch_pic, so that virt machine can set different

bc92f26151 hw/intc: sifive_plic: Fix the pending register range check
The pending register upper limit is currently set to
plic->num_sources >> 3, which is wrong, e.g.: considering
plic->num_sources is 7, the upper limit becomes 0 which fails
the range check if reading the pending register at pending_base.

5decd2c521 hw/intc: sifive_plic: Change "priority-base" to start from interrupt source 0
At present the SiFive PLIC model "priority-base" expects interrupt
priority register base starting from source 1 instead source 0,
that's why on most platforms "priority-base" is set to 0x04 except
'opentitan' machine. 'opentitan' should have set "priority-base"
to 0x04 too.

Note the irq number calculation in sifive_plic_{read,write} is
correct as the codes make up for the irq number by adding 1.

Let's simply update "priority-base" to start from interrupt source
0 and add a comment to make it crystal clear.

59f74489cf hw/riscv: virt: Fix the value of "riscv, ndev" in the dtb
Commit 28d8c28120 ("hw/riscv: virt: Add optional AIA IMSIC support to virt machine")
changed the value of VIRT_IRQCHIP_NUM_SOURCES from 127 to 53, which
is VIRTIO_NDEV and also used as the value of "riscv,ndev" property
in the dtb. Unfortunately this is wrong as VIRT_IRQCHIP_NUM_SOURCES
should include interrupt source 0 but "riscv,ndev" does not.

While we are here, we also fix the comments of platform bus irq range
which is now "64 to 96", but should be "64 to 95", introduced since
commit 1832b7cb3f ("hw/riscv: virt: Create a platform bus").

3a20cd12bf hw/riscv: sifive_e: Fix the number of interrupt sources of PLIC
Per chapter 10 in Freedom E310 manuals [1][2][3], E310 G002 and G003
supports 52 interrupt sources while G000 supports 51 interrupt sources.

We use the value of G002 and G003, so it is 53 (including source 0).

e8fe2bc117 hw/intc: sifive_plic: Update "num-sources" property default value
At present the default value of "num-sources" property is zero,
which does not make a lot of sense, as in sifive_plic_realize()
we see s->bitfield_words is calculated by:

  s->bitfield_words = (s->num_sources + 31) >> 5;

if the we don't configure "num-sources" property its default value
zero makes s->bitfield_words zero too, which isn't true because
interrupt source 0 still occupies one word.

Let's change the default value to 1 meaning that only interrupt
source 0 is supported by default and a sanity check in realize().

While we are here, add a comment to describe the exact meaning of
this property that the number should include interrupt source 0.
