target-sparc: Add and use CPU_FEATURE_CASA
The LEON3 processor has support for the CASA instruction which is
normally only available for SPARC V9 processors. Binutils 2.24
and GCC 4.9 will support this instruction for LEON3. GCC uses it to
generate C11 atomic operations.
The CAS synthetic instruction uses an ASI of 0x80. If TARGET_SPARC64 is
not defined use a supervisor data load/store for an ASI of 0x80 in
helper_ld_asi()/helper_st_asi(). The supervisor data load/store was
choosen according to the LEON3 documentation.
The ASI 0x80 is defined in the SPARC V9 manual, Table 12—Address Space
Identifiers (ASIs). Here we have: 0x80, ASI_PRIMARY, Unrestricted
access, Primary address space.
Tested with the following program:
#include <assert.h>
#include <stdatomic.h>
void test(void)
{
atomic_int a;
int e;
_Bool b;
atomic_store(&a, 1);
e = 1;
b = atomic_compare_exchange_strong(&a, &e, 2);
assert(b);
assert(atomic_load(&a) == 2);
atomic_store(&a, 3);
e = 4;
b = atomic_compare_exchange_strong(&a, &e, 5);
assert(!b);
assert(atomic_load(&a) == 3);
}
Tested also on a NGMP board with a LEON4 processor.

pc: avoid duplicate names for ROM MRs
Since
commit
04920fc0faa4760f9c4fc0e73b992b768099be70
loader: store FW CFG ROM files in RAM
RAM MRs including ROM files in FW CFGs are created
and named using the file basename.
This becomes problematic if these names are
supplied by user, since the basename might not
be unique.
There are two cases we care about:
- option-rom flag.
- option ROM for devices. This triggers e.g. when
using rombar=0.
At the moment we get an assert. E.g
qemu -option-rom /usr/share/ipxe/
8086100e.rom -option-rom
/usr/share/ipxe.efi/
8086100e.rom
RAMBlock "/rom@genroms/
8086100e.rom" already registered, abort!
This is a regression from 1.6.
For now let's keep it simple and just avoid creating the
MRs in case of option ROMs.
when using 1.7 machine types, enable
option ROMs in RAM to match that version.

target-arm: Fix incorrect setting of E bit in CPSR
Commit
4cc35614a moved the exception mask bits out of env->uncached_cpsr
and into env->daif. However the env->daif contents are AArch64 style
mask bits, which include not just the AArch32 AIF bits but also the
new D bit (masks debug exceptions). This means that when reconstructing
the AArch32 CPSR value we must not allow the D bit in env->daif to get
into the CPSR, because the corresponding bit in the CPSR is E, the
endianness bit.
This bug didn't affect execution under TCG because we don't implement
endianness-swapping and so simply ignored the E bit; however it meant
that kernel booting under KVM failed, because KVM does honour the E bit.

vnc: Fix qemu crashed when vnc client disconnect suddenly
Hi,
When I use RealVNC viewer client (http://www.realvnc.com/) to connect vnc server,
the client disconnect suddenly, and I click reconnect button immediately, then the Qemu crashed.
In the function vnc_worker_thread_loop, will call vnc_async_encoding_start
to set the local vs->output buffer by global queue's buffer. Then send rectangles to
the vnc client call function vnc_send_framebuffer_update. Finally, Under normal circumstances,
call vnc_async_encoding_end to set the global queue'buffer by the local vs->output conversely.
When the vnc client disconnect, the job->vs->csock will be set to -1. And the current prcoess
logic will goto disconnected partion without call function vnc_async_encoding_end.
But, the function vnc_send_framebuffer_update will call buffer_reserve, which
maybe call g_realloc reset the local vs's buffer, meaning the global queue's buffer is modified also.
If anyone use the original global queue's buffer memory will cause corruption and then crash qemu.
This patch assure the function vnc_async_encoding_end being called

qemu: x86: ignore ioapic polarity
Both QEMU and KVM have already accumulated a significant number of
optimizations based on the hard-coded assumption that ioapic polarity
will always use the ActiveHigh convention, where the logical and
physical states of level-triggered irq lines always match (i.e.,
active(asserted) == high == 1, inactive == low == 0). QEMU guests
are expected to follow directions given via ACPI and configure the
ioapic with polarity 0 (ActiveHigh). However, even when misbehaving
guests (e.g. OS X <= 10.9) set the ioapic polarity to 1 (ActiveLow),
QEMU will still use the ActiveHigh signaling convention when
interfacing with the emulated ioapic.
This patch modifies the emulated ioapic to completely ignore polarity
as set by the guest OS, enabling misbehaving guests to work alongside
those which comply with the ActiveHigh polarity specified by QEMU's
ACPI tables.

memory: Provide separate handling of unassigned io ports accesses
That is caused by the fact that QEMU reports to
OSPM that device is present by setting 5th bit in

exist.
It happens due to memory_region_present(io_as, 0x2f8)
returning false positive since 0x2f8 address eventually
translates into catchall io_as address space.
Fix memory_region_present(parent, addr) by returning
true only if addr maps into a MemoryRegion within
parent (excluding parent itself), to match its
doc comment.
While at it fix copy/paste error in
memory_region_present() doc comment.
Note: this is a temporary hack: we really need better handling for
unassigned regions, we should avoid fallback regions since they are bad
for performance (breaking radix tree assumption that the data structure
is sparsely populated); for memory we need to fix this to implement PCI

tcg-aarch64: Simplify tcg_out_ldst_9 encoding
At first glance the code appears to be using 1's compliment encoding,
a-la AArch32. Except that the constant is "off", creating a complicated

Much clearer to just use a normal mask and shift.

configure: Always build with -fno-common
MacOSX doesn't pull .o files from .a archives if the symbol that it
requires is one which the .o file defines as a common symbol.
(Common symbols are those declared without "extern"; the linker
will merge together common symbols with the same name, so
redeclaring the same variable in two compilation units results in
them referring to the same symbol rather than a compilation error).
This MacOSX difference from traditional linker behaviour means that
"make check" produces link errors:
Undefined symbols for architecture x86_64:
"_cur_mon", referenced from:
_error_vprintf in libqemuutil.a(qemu-error.o)
_error_printf in libqemuutil.a(qemu-error.o)
_error_printf_unless_qmp in libqemuutil.a(qemu-error.o)
_error_print_loc in libqemuutil.a(qemu-error.o)
_error_report in libqemuutil.a(qemu-error.o)
ld: symbol(s) not found for architecture x86_64
in this case because "cur_mon" is a common symbol in
libqemustub.a(mon-set-error.o).
In QEMU we don't make any use at all of the common symbol
functionality, so we can avoid this problem entirely simply
by compiling with -fno-common. Enable this option for all
builds, not just MacOSX, so that if we ever inadvertently
introduce multiple definitions of some variable that will
be immediately spotted as a build error rather than only
breaking the MacOSX build.

configure: Make C++ test work with --enable-werror
gcc's C++ compiler complains about being passed some -W options
which make sense for C but not for C++. This means we mustn't try
a C++ compile with QEMU_CFLAGS, but only with a filtered version
that removes the offending options. This filtering was already being
done for uses of C++ in the build itself, but was omitted for the
"does C++ work?" configure test. This only showed up when doing
builds which explicitly enabled -Werror with --enable-werror,
because the "do the compilers work" tests were mistakenly placed
above the "default werror based on whether compiling from git" code.
Another error in this category is that clang warns if you ask it to
compile C++ code from a file named "foo.c". Further, because we
were running do_cc in a subshell in the condition part of an "if",
the error_exit inside do_compiler wouldn't terminate configure and
we would plunge on regardless. Fix this complex of errors:
1. Move the default-werror code up so that there are no invocations
of compile_object and friends between it and the point where we
set $werror explicitly based on the --enable-werror command line
option.
2. Provide a mechanism for filtering QEMU_CFLAGS to create
QEMU_CXXFLAGS, and use it for the test we run here.
3. Provide a do_cxx function to run a test with the C++ compiler
rather than doing cute tricks with subshells and do_cc.
4. Use a new temporary file TMPCXX for the C++ program fragment.
