  spapr/xive: use the VCPU id as a NVT identifier (2018-12-13 09:44:04 +1100)

----------------------------------------------------------------
ppc patch queue 2018-12-13

Here's the first ppc and spapr pull request for 4.0.  Highlights are:

 * The start of support for the POWER9 "XIVE" interrupt controller
   (not complete enough to use yet, but we're getting there)
 * A number of g_new vs. g_malloc cleanups
 * Some IRQ wiring cleanups
 * A fix for how we advertise NUMA nodes to the guest for pseries

Compile errors in the windows cross-build. These look like
they're assumptions that "long" is 64 bits, which it is not on Windows.
For instance the PPC_BIT macro should be using the ULL suffix, not UL
("UL" is almost always a bug: either the constant is 32-bit, in
which case "U" is what you want, or it's 64-bit and you need "ULL").

Using __builtin_ffsl() directly in target/ppc/cpu.h also looks
a bit dubious -- this should be rephrased to use ctz32() or ctz64()
instead.

are you compiling with the mingw64-* packages ? as documented in :

ok. These definitions come from our skiboot firmware which I wanted 
to keep as it was. It seems I will need to adapt.

ok. I will work on a fix.

So, I tried to confirm the problem, before applying Cédric's fix, but

Hi,

We had a discussion about the strncpy errors and windows builds
SIGSEGV-ing here:
https://lists.nongnu.org/archive/html/qemu-devel/2018-08/msg03310.html

A solution was suggested here:
https://lists.nongnu.org/archive/html/qemu-devel/2018-08/msg03761.html.

Nevertheless, I still compile with --disable-werror and
--disable-stack-protector to get a working binary. (Cross-compiling on
Fedora 29).

Best,
Howard

I am still using f28. Another reason to update.

I gave it a try on a f29 with : 

  $ x86_64-w64-mingw32-gcc --version 
  x86_64-w64-mingw32-gcc (GCC) 8.2.0 20180726 (Fedora MinGW 8.2.0-3.fc29)

and it compiles if configured with --disable-werror as suggested by Howard.

Anyhow, we need to discuss a little more on the cpu.h fix, regarding the ctz, 
and the hcalls also need some fixing :

  -        qemu_log_mask(LOG_GUEST_ERROR, "XIVE: Unknown LISN %lx\n", lisn);
  +        qemu_log_mask(LOG_GUEST_ERROR, "XIVE: Unknown LISN " TARGET_FMT_lx "\n",
  +                      lisn);


For v9. 

Thanks,
 
C.
