There is a defined RETRY_ON_EINTR() macro in qemu/osdep.h
which handles the same while loop.

The pending register upper limit is currently set to

plic->num_sources is 7, the upper limit becomes 0 which fails

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").

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.

592f0a9429 hw/{misc, riscv}: pfsoc: add system controller as unimplemented
The system controller on PolarFire SoC is access via a mailbox. The
control registers for this mailbox lie in the "IOSCB" region & the
interrupt is cleared via write to the "SYSREG" region. It also has a
QSPI controller, usually connected to a flash chip, that is used for
storing FPGA bitstreams and used for In-Application Programming (IAP).

Linux has an implementation of the system controller, through which the
hwrng is accessed, leading to load/store access faults.

Add the QSPI as unimplemented and a very basic (effectively
unimplemented) version of the system controller's mailbox. Rather than
purely marking the regions as unimplemented, service the mailbox
requests by reporting failures and raising the interrupt so a guest can
better handle the lack of support.

8d32e374a8 hw/riscv: pfsoc: add missing FICs as unimplemented
The Fabric Interconnect Controllers provide interfaces between the FPGA
fabric and the core complex. There are 5 FICs on PolarFire SoC, numbered
0 through 4. FIC2 is an AXI4 slave interface from the FPGA fabric and
does not show up on the MSS memory map. FIC4 is dedicated to the User
Crypto Processor and does not show up on the MSS memory map either.

FIC 0, 1 & 3 do show up in the MSS memory map and neither FICs 0 or 1
are represented in QEMU, leading to load access violations while booting
Linux for Icicle if PCIe is enabled as the root port is connected via
either FIC 0 or 1.

13cd1d6eaf hw/misc: pfsoc: add fabric clocks to ioscb
On PolarFire SoC, some peripherals (eg the PCI root port) are clocked by
"Clock Conditioning Circuitry" in the FPGA. The specific clock depends
on the FPGA bitstream & can be locked to one particular {D,P}LL - in the
Icicle Kit Reference Design v2022.09 or later this is/will be the case.

Linux v6.1+ will have a driver for this peripheral and devicetrees that
previously relied on "fixed-frequency" clock nodes have been switched
over to clock-controller nodes. The IOSCB region is represented in QEMU,
but the specific region of it that the CCCs occupy has not so v6.1-rcN
kernels fail to boot in QEMU.

Add the regions as unimplemented so that the status-quo in terms of boot
is maintained.

The imsic DT binding[1] has changed and no longer require an ipi-id.
The latest IMSIC driver dynamically allocates ipi id if slow-ipi

None of our code base require / use inlined functions with external
linkage. Some places use internal inlining in the hot path. These
two functions are certainly not in any hot path and don't justify
any inlining, so these are likely oversights rather than intentional.

e662449aa6 hw/timer/imx_epit: remove explicit fields cnt and freq
The CNT register is a read-only register. There is no need to
store it's value, it can be calculated on demand.
The calculated frequency is needed temporarily only.

Note that this is a migration compatibility break for all boards
types that use the EPIT peripheral.
