[PULL 16/76] hw/i386/pc: Remove deprecated pc-i440fx-2.2 machine

release (see commit c7437f0ddb "docs/about: Mark the
old pc-i440fx-2.0 - 2.3 machine types as deprecated"),
time to remove it.

release (see commit c7437f0ddb "docs/about: Mark the
old pc-i440fx-2.0 - 2.3 machine types as deprecated"),
time to remove it.

[PULL 52/76] hw/intc: Introduce x-query-interrupt-controllers QMP command

[Philippe Mathieu-Daudé]

This is a counterpart to the HMP "info pic" command. It is being
added with an "x-" prefix because this QMP command is intended as an
adhoc debugging tool and will thus not be modelled in QAPI as fully
structured data, nor will it have long term guaranteed stability.
The existing HMP command is rewritten to call the QMP command.

[PULL 53/76] ppc/pnv: Introduce pnv_chip_foreach_cpu()

[Philippe Mathieu-Daudé]

From: Cédric Le Goater <clg@redhat.com>

This helper routine uses the machine definition, sockets, cores and
threads, to loop on all CPUs of the machine. Replace CPU_FOREACH()
with it.

[PULL 54/76] target/arm: Set arm_v7m_tcg_ops cpu_exec_halt to arm_cpu_exec_halt()

[Philippe Mathieu-Daudé]

From: Peter Maydell <peter.maydell@linaro.org>

In commit a96edb687e76 we set the cpu_exec_halt field of the
TCGCPUOps arm_tcg_ops to arm_cpu_exec_halt(), but we left the
arm_v7m_tcg_ops struct unchanged.  That isn't wrong, because for
M-profile FEAT_WFxT doesn't exist and the default handling for "no
cpu_exec_halt method" is correct, but it's perhaps a little
confusing.  We would also like to make setting the cpu_exec_halt
method mandatory.

Initialize arm_v7m_tcg_ops cpu_exec_halt to the same function we use
for A-profile.  (On M-profile we never set up the wfxt timer so there
is no change in behaviour here.)

[PULL 55/76] target: Set TCGCPUOps::cpu_exec_halt to target's has_work implementation

[Philippe Mathieu-Daudé]

From: Peter Maydell <peter.maydell@linaro.org>

Currently the TCGCPUOps::cpu_exec_halt method is optional, and if it
is not set then the default is to call the CPUClass::has_work
method (which has an identical function signature).

We would like to make the cpu_exec_halt method mandatory so we can
remove the runtime check and fallback handling.  In preparation for
that, make all the targets which don't need special handling in their
cpu_exec_halt set it to their cpu_has_work implementation instead of
leaving it unset.  (This is every target except for arm and i386.)

In the riscv case this requires us to make the function not
be local to the source file it's defined in.

[PULL 56/76] accel/tcg: Make TCGCPUOps::cpu_exec_halt mandatory

mandatory and remove the fallback handling that calls cpu_has_work.

[PULL 63/76] hw/intc/loongson_ipi: Provide per core MMIO address spaces

[Philippe Mathieu-Daudé]

From: Jiaxun Yang <jiaxun.yang@flygoat.com>

The real IPI hardware have dedicated MMIO registers mapped into
memory address space for every core. This is not used by LoongArch
guest software but it is essential for CPU without IOCSR such as
Loongson-3A1000.

Implement it with existing infrastructure.

[PULL 65/76] hw/mips/loongson3_virt: Wire up loongson_ipi device

[Philippe Mathieu-Daudé]

From: Jiaxun Yang <jiaxun.yang@flygoat.com>

Wire up loongson_ipi device for loongson3_virt machine, so we
can have SMP support for TCG backend as well.

[PULL 67/76] target/s390x: Use s390_skeys_get|set() helper

[Philippe Mathieu-Daudé]

Commit c9274b6bf0 ("target/s390x: start moving TCG-only code
to tcg/") moved mem_helper.c, but the trace-events file is
still in the parent directory, so is the generated trace.h.

Call the s390_skeys_get|set() helper, removing the need
for the trace event shared with the tcg/ sub-directory,
fixing the following build failure:

 In file included from ../target/s390x/tcg/mem_helper.c:33:
 ../target/s390x/tcg/trace.h:1:10: fatal error: 'trace/trace-target_s390x_tcg.h' file not found

[PULL 68/76] util/readline: Fix lints for readline_handle_byte

[Philippe Mathieu-Daudé]

From: Manos Pitsidianakis <manos.pitsidianakis@linaro.org>

While they do not give warnings under our current buildsystem
configuration, my clang's language server daemon was complaining about
missing default: labels in switch statements.

While at it, add /* fallthrough */ annotations where appropriate.

This is a purely style and not functional change.

Add support for the unix-line-discard readline action, which erases from

This is useful to quickly erase command input while working on the

[Philippe Mathieu-Daudé]

From: Gerd Hoffmann <kraxel@redhat.com>

In case the display surface uses a shared buffer (i.e. uses vga vram
directly instead of a shadow) go unshare the buffer before clearing it.

This avoids vga memory corruption, which in turn fixes unblanking not
working properly with X11.

[PULL 76/76] ui+display: rename is_buffer_shared() -> surface_is_allocated()

[Philippe Mathieu-Daudé]

From: Gerd Hoffmann <kraxel@redhat.com>

Boolean return value is reversed, to align with QEMU_ALLOCATED_FLAG, so
all callers must be adapted.  Also rename share_surface variable in
vga_draw_graphic() to reduce confusion.

No functional change.

Doh sorry, I tested but hit a libusb issue on this target and mingw64,
tested there and thought this was the only issue and missed that.

Hmm cpu_has_work() is defined inlined. I'll just drop the 3 lines
I added to Peter's patch and send his unmodified.

Phil.

No, the assert is exactly correct, and caught a bug in the previous patch (55/76).
Without your assert, we will just SEGV in cpu_handle_halt instead with patch (56/76).

Yeah, it was too late here to realize that.

Peter, I'll respin without your series. Do you mind taking your
"target/arm: Set arm_v7m_tcg_ops cpu_exec_halt to arm_cpu_exec_halt"
patch via your ARM tree, that way I don't delay you further.

Thanks,

Phil.

Sure, I can do that. (I don't think this series particularly
is likely to conflict with anything else in flight.)

Coverity mentions a  Null pointer dereference (REVERSE_INULL) here
(CID 1547264):

   Null-checking "ipi" suggests that it may be null, but it has
   already been dereferenced on all paths leading to the check.

Maybe this silences it:

  -        if (ipi) {
  +        if (!kvm_enabled()) {

Still I'd rather using tcg_enabled() in this file.

Do you mind posting a patch fixing it?

Yep, we're missing the setup of .cpu_exec_halt for tricore.
I missed this because I used a grep for the setup of .cpu_exec_interrupt
to find all the TCGCPUOps I needed to update, and for some reason
tricore doesn't implement that hook. (This surprises me because
I expected every guest CPU to need to provide handling for
interrupts. But looking at the callsite in accel/tcg it does
indeed allow a target to leave cpu_exec_interrupt NULL.)

Though we won't ever segv without the assert() in patch 3:
tricore doesn't implement a halt state, so we won't ever
try to call the non-existent cpu_exec_halt method. (This is
why my local testing didn't catch the missing method.)

Anyway, I've squashed this in to patch 2 and re-queued the
series to target-arm.next:
