Hi list,
When I did some tests in my virtual domain with live-attached virtio deivces, I
got a coredump file of Qemu.
The error print from qemu is "kvm_mem_ioeventfd_add: error adding ioeventfd:
File exists (17)".
And the call trace in the coredump file displays as below:

Having looked a bit more carefully at the architecture
manual, I think this is not complete.
Our decoding of fence-instructions is problematic in respect to the
RISC-V ISA specification:
- rs and rd are ignored, but need to be 0
- fm is ignored
This change adjusts the decode pattern to enfore rs and rd being 0,
and validates the fm-field (together with pred/succ for FENCE.TSO) to
The RISC-V specification specifies imm12, rs1 and rd to be all-zeros,
so we can't ignore these bits when decoding into fence.i.
Update the decode pattern to reflect the specification.

Happy to lower it back into the decode file.
However, I initially pulled it up into the trans-function to more
closely match the ISA specification: there is only one FENCE

With the introduction of the new TCG GICv4, build_madt() is badly broken
as we do not present any GIC Redistributor structure in MADT for GICv4
guests, so that they have no idea about where the Redistributor
register frames are. This fixes a Linux guest crash at boot time with

Pass these along to translator_loop -- pc may be used instead
of tb->pc, and host_pc is currently unused. Adjust all targets
at one time.

We will want to re-use the result of get_page_addr_code

The mmap_lock is held around tb_gen_code. While the comment
is correct that the lock is dropped when tb_gen_code runs out
of memory, the lock is *not* dropped when an exception is
raised reading code for translation.

Map the stack executable if required by default or on demand.

Introduce a function that checks whether a given address is on the same
page as where disassembly started. Having it improves readability of
the following patches.

We currently ignore PROT_EXEC on the initial lookup, and
defer raising the exception until cpu_ld*_code().
It makes more sense to raise the exception early.

The function assumes that we're always dealing with a PNV9_CHIP()
object. This is not the case when the pnv-phb device belongs to a
powernv10 machine.
Change pnv_phb4_get_pec() to be able to work with PNV10_CHIP() if
necessary.

cpu64.c has ended up in a slightly odd order -- it starts with the
initfns for most of the models-real-hardware CPUs; after that comes a
bunch of support code for SVE, SME, pauth and LPA2 properties. Then
come the initfns for the 'host' and 'max' CPU types, and then after
that one more
The only user can easily use translator_lduw and
adjust the type to signed during the return.

This is part of a larger body of work, but in the process of
reorganizing I was reminded that PROT_EXEC wasn't being enforced
properly for user-only. As this has come up in the context of
some of Ilya's patches, I thought I'd go ahead and post this part.

We're about to start validating PAGE_EXEC, which means
that we've got to put this code into a section that is
both writable and executable.
Note that this test did not run on hardware beforehand either.

We're about to start validating PAGE_EXEC, which means
that we've got to mark the commpage executable. We had
been placing the commpage outside of reserved_va, which
was incorrect and lead to an abort.

got to the vsyscall page executable. We had been special casing
