7 years agoDon't enable a HPET timer if HPET is disabled
Matt Lupfer [Sat, 22 Feb 2014 04:37:23 +0000 (21:37 -0700)] 
Don't enable a HPET timer if HPET is disabled

A HPET timer can be started when HPET is not yet
enabled. This will not generate an interrupt
to the guest, but causes problems when HPET is later
enabled.

A timer that is created and expires at least once before
HPET is enabled will have an initialized comparator based
on a hpet_offset of 0 (uninitialized). When HPET is
enabled, hpet_set_timer() is called a second time, which
modifies the timer expiry to a time based on the
difference between current ticks (measured with the
newly initialized hpet_offset) and the timer's
comparator (which was generated before hpet_offset was
initialized). This results in a long period of no HPET
timer ticks.

When this occurs with a CentOS 5.x guest, the guest
may not receive timer interrupts during its narrow
timer check window and panic on boot.

hw/arm: Stop specifying integratorcp as the default board

Currently for both qemu-system-arm and qemu-system-aarch64
the default board model if the user doesn't specify one
is the 'integratorcp'. This is a totally arbitrary historical
accident since it was the first board to be modelled.
That board is now just one target among many for us, and
is a very poor choice of default:
 * it's an ancient board that is now only found in the
   junkpiles of longtime ARM/Linux hackers, if at all
 * it's an ARMv5 CPU, when most distros are now assuming
   ARMv7
 * it's pretty much unmaintained in QEMU
 * it doesn't even have versatilepb's advantage of
   supporting PCI

Making it or any other board the default serves only
to confuse people new to ARM who expect something more
like the x86 monoculture. Remove the is_default marker
from integratorcp, and don't set it for any other board,
to give users a nudge that they need to think about
which board they want a QEMU model of. (QEMU will produce
the admittedly slightly cryptic error "No machine found.")

acpi: make SSDT 1.0 spec compliant when possible

The ACPI specification says:

The ASL compiler can emit two different AML opcodes for a Package
declaration, either PackageOp or VarPackageOp. For small, fixed-length
packages, the PackageOp is used and this opcode is compatible with ACPI
1.0. A VarPackageOp will be emitted if any of the following conditions
are true:
. The NumElements argument is a TermArg that can only be resolved at
runtime.
. At compile time, NumElements resolves to a constant that is larger than
255.
. The PackageList contains more than 255 initializer elements.
Note: The ability to create variable-sized packages was first introduced
in ACPI 2.0. ACPI 1.0 only allowed fixed-size packages with up to 255 elements.

So the spec seems to say a fixed value up to 255 must always
be used with PackageOp and not VarPackageOp, and some guests
(windows up to win2k8) seem to interpret it like this.

Let's do just this, choosing the encoding depending on
the number of elements.

Fixes 9bcc80cd71892df42605e0c097d85c0237ff45d1
(i386/acpi-build: allow more than 255 elements in CPON).

7 years agoosdep: initialize glib threads in all QEMU tools
Stefan Hajnoczi [Tue, 8 Oct 2013 09:58:31 +0000 (11:58 +0200)] 
osdep: initialize glib threads in all QEMU tools

glib versions prior to 2.31.0 require an explicit g_thread_init() call
to enable multi-threading.

Failure to initialize threading causes glib to take single-threaded code
paths without synchronization.  For example, the g_slice allocator will
crash due to race conditions.

Fix this for all QEMU tool programs (qemu-nbd, qemu-io, qemu-img) by
moving the g_thread_init() call from vl.c:main() into a new
osdep.c:thread_init() constructor function.

thread_init() has __attribute__((constructor)) and is automatically
invoked by the runtime during startup.

We can now drop the "simple" trace backend's g_thread_init() call since
thread_init() already called it.

Note that we must keep coroutine-gthread.c's g_thread_init() call which
is located in a constructor function.  There is no guarantee for
constructor function ordering so thread_init() may only be called later.
