Hi,
The patch below allows me to compile qemu on Windows, however it is still
not working.
The program exits immediately reporting that it can't open the hard disk
image.
GDB reports the offensive pies of code is in malloc(), which does not make
sense to me.
Am I doing something wrong?

I was trying to add signalfd support on qemu-ppc (specifically, I'm
doing a configure with "--enable-debug-tcg --enable-debug
--disable-strip --disable-kvm --disable-bsd-user --disable-darwin-user
--enable-profiler --target-list=ppc-linux-user --disable-curl
--enable-nptl").
At first I thought tha
I have read that one of the reasons for using makecontext is that it
saves the signal state. But there also exist functions like
"sigsetjmp" and "siglongjmp" which can be used to jump around the
coroutines while preserving signal masks.
I have a patch that uses sigsetjmp and siglongjmp instead of

Embedding the struct means we need to know the size, which means we
can't get rid of the #ifdef. Probably better to use a pointer if we
don't mind adding a few bytes in the #ifndef case. Thanks,

to a group to something like vfio binding to that group and
creating a chardev to access it? Are we manipulating automatic driver
binding or existing bound drivers once a group is bound? Do isolation
groups enforce isolation, or just describe it? Thanks,

As we start to enable 64bit I/O devices, there's a good chance
we'll find bugs and compatibility issues. This allows a user
to toggle off (default on) 64bit PCI MMIO BARs, downgrading
them to 32bit BARs.

I am barely able to understand this inline function:
static inline int sas_ss_flags(unsigned long sp)
{
return (target_sigaltstack_used.ss_size == 0 ? SS_DISABLE
: on_sig_stack(sp) ? SS_ONSTACK : 0);
}
(signal.c @97)
... and it seems wrong to me when used in the following function

sorry, something like "Incorrect zero comparison in sas_ss_flags"
would have
done wrong only for this
architecture, it's more a typo than a bug). It's NOT ppc specific,
it's POSIX standard (sigaltstack) and qemu internal.
I have a test source that I will send in a follow-up (it's longer than
I would have wished, I'm sure that a better test case can be
// Test source and desired /real output:
#include
#include
#include
#include
void handler(int sig)
{
unsigned int a;
// to prevent uninitialized stack, normally a = 0
if ( a>10 ) a = 0;
a = a + 1;
printf ("new value: %d\n" , a );
if (a > 7) _exit(a);
return;
}
int main()
I have sent a v2 of this patch (renaming it, with a description and a
test case). If it's not trivial and I have to send it in another way,
I will do so.
Sorry for the inconvenience, as I said I'm new here and maybe I
misunderstood the "trivial" category.
(file pth_mctx.c, variant 2).
It's my first patch, I'm sure that there are things that I
have done wrong. Please, be kind :)
Thanks for your time

This file is based in both coroutine-ucontext.c and
pth_mctx.c (from the GNU Portable Threads library).
The mechanism used to change stacks is the sigaltstack
function (variant 2 of the pth library).
