It's found that some of the CPU type names in the array of valid
CPU types are invalid because their corresponding classes aren't
registered, as reported by Peter Maydell.
[gshan@gshan build]$ ./qemu-system-arm -machine virt -cpu cortex-a9
qemu-system-arm: Invalid CPU model: cortex-a9
The valid models are: cortex-a7, cortex-a15, (null), (null), (null),
(null), (null), (null), (null), (null), (null), (null), (null), max
Fix it by consolidating the array of valid CPU types. After it's
applied, we have the following output when TCG is enabled.
[gshan@gshan build]$ ./qemu-system-arm -machine virt -cpu cortex-a9
qemu-system-arm: Invalid CPU model: cortex-a9

uintptr_t, or unsigned long which is equivalent on Linux I32LP64 systems,
is an unsigned type and there is no need to further cast to __u64 which is
another unsigned integer type; widening casts from unsigned integers
zero-extend the value.

Jazz Jackrabbit has a very unusual VGA setup, where it uses odd/even mode
with 256-color graphics. Probably, it wants to use fast VRAM-to-VRAM
copies without having to store 4 copies of the sprites as needed in mode
X, one for each mod-4 alignment; odd/even mode simplifies the code a
lot if it's okay to place on a 160-pixels horizontal grid.
At the same time, because it wants to use double buffering (a la "mode X")
it uses byte mode, not word mode as is the case in text modes. In order
to implement the combination of odd/even mode (plane number comes from
bit 0 of the address) and byte mode (use all bytes of VRAM, whereas word
mode only uses bytes 0, 2, 4,... on each of the four planes), we need
to separate the effect on the plane number from the effect on the address.
Implementing the modes properly is a mess in QEMU, because it would
change the layout of VRAM and break migration. As an approximation,
shift right when the CPU accesses memory instead of shifting left when
the CRT controller reads it. A hack is needed in order to write font data
properly (see comment in the code), but it works well enough for the game.
Because doubleword and chain4 modes are now independent, chain4 does not
assert anymore that the address is in range. Instead it just returns
all ones and discards writes, like other modes.

Jazz Jackrabbit uses odd/even mode with 256-color graphics. This is
probably so that it can do very fast blitting with a decent resolution
(two pixels, compared to four pixels for "regular" mode X).
Accesses still use all planes (reads go to the latches and the game uses
read mode 1 so that the CPU always gets 0xFF; writes use the plane mask
register because the game sets bit 2 of the sequencer's memory mode
register). For this to work, QEMU needs to use the code for latched
memory accesses in odd/even mode. The only difference between odd/even
mode and "regular" planar mode is how the plane is computed in read mode
0, and how the planes are masked if the aforementioned bit 2 is reset.
It is almost enough to fix the game. You also need to honor byte/word
mode selection, which is done in the next patch.

The next patch will reuse latched memory access in text modes. Start with
a patch that moves the latched access code out of the "if".

Do not go through the panning buffer unless the address wraps in the middle
of the line.

This implements smooth scrolling, as used for example by Commander Keen
and Second Reality.
Unfortunately, this is not enough to avoid tearing in Commander Keen,
because sometimes the wrong start address is used for a frame.
On real EGA, the panning register is sampled on every line, while
the display start is latched for the next frame at the start of the
vertical retrace. On real VGA, the panning register is also latched,
but at the end of the vertical retrace. It looks like Keen exploits
this by only waiting for horizontal retrace when setting the display
start, but implementing it breaks the 256-color Keen games...

This allows setting the start address to a high value, and reading the
bottom of the screen from the beginning of VRAM. Commander Keen 4
("Goodbye, Galaxy!") relies on this behavior.

target/hppa qemu v8.2 regression fixes
There were some regressions introduced with Qemu v8.2 on the hppa/hppa64
target, e.g.:
- 32-bit HP-UX crashes on B160L (32-bit) machine
- NetBSD boot failure due to power button in page zero
- NetBSD FPU detection failure
- OpenBSD 7.4 boot failure
This patch series fixes those known regressions and additionally:
- allows usage of the max. 3840MB of memory (instead of 3GB),
- adds support for the qemu --nodefaults option (to debug other devices)
This patch set will not fix those known (non-regression) bugs:
- HP-UX and NetBSD still fail to boot on the new 64-bit C3700 machine
- Linux kernel will still fail to boot on C3700 as long as kernel modules are used.
Changes v2->v3:
- Added comment about Figures H-10 and H-11 in the parisc2.0 spec
in patch which calculate PDC address translation if PSW.W=0
- Introduce and use hppa_set_ior_and_isr()
- Use drive_get_max_bus(IF_SCSI), nd_table[] and serial_hd() to check
if default devices should be created
- Added Tested-by and Reviewed-by tags
Changes v1->v2:
- fix OpenBSD boot with SeaBIOS v15 instead of v14
- commit message enhancements suggested by BALATON Zoltan
- use uint64_t for ram_max in patch #1

The various operating systems (e.g. Linux, NetBSD) have issues
mapping the power button when it's stored in page zero.
NetBSD even crashes, because it fails to map that page and then
accesses unmapped memory.
Since we now have a consistent memory mapping of PDC in 32-bit
and 64-bit address space (the lower 32-bits of the address are in
sync) the power button can be moved back to PDC space.
This patch fixes the power button on Linux, NetBSD and HP-UX.

Recognize the qemu --nodefaults option, which will disable the
following default devices on hppa:
- lsi53c895a SCSI controller,
- artist graphics card,
- LASI 82596 NIC,
- tulip PCI NIC,
- second serial PCI card,
- USB OHCI controller.
Adding this option is very useful to allow manual testing and
debugging of the other possible devices on the command line.

The physical hardware allows DIMMs of 4 MB size and above, allowing up
to 3840 MB of memory, but is restricted by setup code to 3 GB.
Increase the limit to allow up to the maximum amount of memory.
Btw. the memory area from 0xf000.0000 to 0xffff.ffff is reserved by
the architecture for firmware and I/O memory and can not be used for
standard memory.
An upcoming 64-bit SeaBIOS-hppa firmware will allow more than 3.75GB
on 64-bit HPPA64. In this case the ram_max for the pa20 case will change.

As commit 3e015d815b3f ("use g_path_get_basename instead of basename")
said, g_path_get_dirname() should be preferred over dirname() since
the former is a portable utility function that has the advantage of not
modifying the string argument.
Replace dirname() with g_path_get_dirname().

g_path_get_basename() is a portable utility function that has the
advantage of not modifying the string argument, so it should be
preferred over basename().
And also to avoid potential compile breakage with the Musl C library
similar to [1], replace basename() with g_path_get_basename().

It's a common scenario to copy guest images from one host to another
to run the guest on the other machine. This (of course) does not work
with "secure execution" guests since they are encrypted with one certain
host key. However, if you still (accidentally) do it, you only get a
very user-unfriendly error message that looks like this:
qemu-system-s390x: KVM PV command 2 (KVM_PV_SET_SEC_PARMS) failed:
header rc 108 rrc 5 IOCTL rc: -22
Let's provide at least a somewhat nicer hint to the users so that they
are able to figure out what might have gone wrong.

On LoongArch physical machine, one extioi interrupt controller only
supports 4 cpus. With processor more than 4 cpus, there are multiple
extioi interrupt controllers; if interrupts need to be routed to
other cpus, they are forwarded from extioi node0 to other extioi nodes.
On virt machine model, there is simple extioi interrupt device model.
All cpus can access register of extioi interrupt controller, however
interrupt can only be route to 4 vcpu for compatible with old kernel.
This patch adds dynamic cpu number support about extioi interrupt.
With old kernel legacy extioi model is used, however kernel can detect
and choose new route method in future, so that interrupt can be routed to
all vcpus.

LoongArch system has iocsr address space, most iocsr registers are
per-board, however some iocsr register spaces banked for percpu such
as ipi mailbox and extioi interrupt status. For banked iocsr space,
each cpu has the same iocsr space, but separate data.
This patch changes iocsr address space per-board rather percpu,
for iocsr registers specified for cpu, MemTxAttrs.requester_id
can be parsed for the cpu. With this patches, the total address space
on board will be simple, only iocsr address space and system memory,
rather than the number of cpu and system memory.

There are two interface pairs for MemoryRegionOps, read/write and
read_with_attrs/write_with_attrs. The later is better for ipi device
emulation since initial cpu can be parsed from attrs.requester_id.
And requester_id can be overrided for IOCSR_IPI_SEND and mail_send
function when it is to forward message to another vcpu.

QEMU already implements zicbom (Cache Block Management Operations) and
zicboz (Cache Block Zero Operations). Commit 59cb29d6a5 ("target/riscv:
add Zicbop cbo.prefetch{i, r, m} placeholder") added placeholders for
what would be the instructions for zicbop (Cache Block Prefetch
Operations), which are now no-ops.
The RVA22U64 profile mandates zicbop, which means that applications that
run with this profile might expect zicbop to be present in the riscv,isa
DT and might behave badly if it's absent.
Adding zicbop as an extension will make our future RVA22U64
implementation more in line with what userspace expects and, if/when
cache block prefetch operations became relevant to QEMU, we already have
the extension flag to turn then on/off as needed.

ACPI DSDT generator needs information like ECAM range, PIO range, 32-bit
and 64-bit PCI MMIO range etc related to the PCI host bridge. Instead of
making these values machine specific, create properties for the GPEX
host bridge with default value 0. During initialization, the firmware
can initialize these properties with correct values for the platform.
This basically allows DSDT generator code independent of the machine
specific memory map accesses.

The hypervisor can deliver (virtual) LPIs to a guest by setting up a
list register to have an intid which is an LPI. The GIC has to treat
these a little differently to standard interrupt IDs, because LPIs
have no Active state, and so the guest will only EOI them, it will
not also deactivate them. So icv_eoir_write() must do two things:
* if the LPI ID is not in any list register, we drop the
priority but do not increment the EOI count
* if the LPI ID is in a list register, we immediately deactivate
it, regardless of the split-drop-and-deactivate control
This can be seen in the VirtualWriteEOIR0() and VirtualWriteEOIR1()
pseudocode in the GICv3 architecture specification.
Without this fix, potentially a hypervisor guest might stall because
LPIs get stuck in a bogus Active+Pending state.
