Eduardo Habkost 07d01c9c19 smbios: Don't report unknown CPU speed (fix SVVP regression)
SVVP requires processor speed on Type 4 structures to not be unknown.
This was fixed in SeaBIOS 0.5.0 (in 2009), but the bug was reintroduced
in QEMU 2.1.

Revert to old behavior and report CPU speed as 2000 MHz instead of
unknown.

Bastian Koppelmann 85d604af5f target-tricore: split up suov32 into suov32_pos and suov32_neg
suov checks unsigned for an overflow and an underflow, after some arithmetic
operations and saturates the result to either max_uint32 or 0. So far we
handled this by expanding to the next bigger data type and compare whether
the result is > max_uint32 or < 0.

However this approach can fail for an 32 bit multiplication, if both operands of
the multiplication are 0x80000000. This sets the sign bit of the 64 bit integer
and would result in a false saturation to 0.

Since unsigned operations, e.g add, sub, mul always result in either a positive
or negative overflow, we split the functions for suov32 up into two functions
(suov32_pos, suov32_neg) for each case.

This fixes one bug and one false positive found by coverity. The bug is,
that gen_mtcr was missing a mask to check the flag, which resulted in dead code.

The false positive is a intentional missing break for a jump and link address
insn followed by a jump and link insn. This adds a fall through comment to avoid
the false positive in the future.

Alexander Graf 27fb9688f9 pci: Split pcie_host_mmcfg_map()
The mmcfg space is a memory region that allows access to PCI config space
in the PCIe world. To maintain abstraction layers, I would like to expose
the mmcfg space as a sysbus mmio region rather than have it mapped straight
into the system's memory address space though.

So this patch splits the initialization of the mmcfg space from the actual
mapping, allowing us to only have an mmfg memory region without the map.

Amit Shah 6ac0d8d44c ich9: add disable_s3, disable_s4, s4_val properties
PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM
functions.  Add such properties to the ICH9 chipset as well for the Q35
machine type.

S3 / S4 are not guaranteed to always work (needs work in the guest as
well as QEMU for things to work properly), and disabling advertising of
these features ensures guests don't go into zombie state if something
isn't working right.

The defaults are kept the same as in PIIX4: both S3 and S4 are enabled
by default.

These can be disabled via the cmdline:

  ... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1

Note: some guests can fake hibernation by writing a hibernate image and
doing a shutdown instead of S4 if S4 isn't available; there's nothing we
can do guests to stop doing this, and this patch can't affect that
functionality.

Peter Maydell 1ac0206b2a qemu-timer.c: Trim list of included headers
qemu-timer.c was including a lot more headers than it needed to,
presumably for historical reasons. In particular, it included
ui/console.h; this now tries to pull in <pixman.h>, which will
cause a compilation failure in --disable-tools --disable-system
configurations when running "make check" (which builds qemu-timer.c,
even though the linux-user binaries themselves don't need it).

Fix this build failure by trimming down the set of included
headers severely -- we only really need main-loop.h and timer.h.

Wei Huang fc116efad0 kvm_stat: Add RESET support for perf event ioctl
While running kvm_stat using tracepoint on ARM64 hardware (e.g. "kvm_stat
-1 -t"), the initial values of some kvm_userspace_exit counters were found
to be very suspecious. For instance the tracing tool showed that S390_TSCH
was called many times on ARM64 machine, which apparently was wrong.

This patch adds RESET ioctl support for perf monitoring. Before calling
ioctl to enable a perf event, this patch resets the counter first. With
this patch, the init counter values become correct on ARM64 hardware.

Example:

==== before patch ====
kvm_userspace_exit(S390_SIEIC)      1426         0
kvm_userspace_exit(S390_TSCH)       339         0

==== after patch ====
kvm_userspace_exit(S390_SIEIC)         0         0
kvm_userspace_exit(S390_TSCH)         0         0

Right now you only get to apic_init_reset if you have an APIC
(do_cpu_init is reached only if CPU_INTERRUPT_INIT is set and
that only happens in hw/intc/apic.c).  However, this is wrong
because for example a port 92 or keyboard controller reset is
really an INIT, and that can happen also with no APIC.  So
keep the check and fix the error that Coverity reported.

Wei Huang 874b1cfad5 kvm_stat: Print errno when syscall to perf_event_open() fails
kvm_stat uses syscall() to call perf_event_open(). If this function
call fails, the returned value is -1, which doesn't tell the details
of such failure (i.e. ENOSYS or EINVAL). This patch retrieves errno
and prints it when syscall() fails. The error message will look like
"Exception: perf_event_open failed, errno = 38".

Jiri Slaby b30934cb52 hw: misc, add educational driver
I am using qemu for teaching the Linux kernel at our university. I
wrote a simple PCI device that can answer to writes/reads, generate
interrupts and perform DMA. As I am dragging it locally over 2 years,
I am sending it to you now.

Paolo Bonzini cd1bd53a66 qemu-timer: introduce timer_deinit
In some cases, a timer was set to NULL so that we could check if it is
initialized.  Use the timer_list field instead, and add a timer_deinit
function that NULLs it.

It then makes sense that timer_del be a no-op (instead of a crasher) on
such a de-initialized timer.  It avoids the need to poke at the timerlist
field to check if the timers are initialized.

Paolo Bonzini b7711471f5 target-i386: make xmm_regs 512-bit wide
Right now, the AVX512 registers are split in many different fields:
xmm_regs for the low 128 bits of the first 16 registers, ymmh_regs
for the next 128 bits of the same first 16 registers, zmmh_regs
for the next 256 bits of the same first 16 registers, and finally
hi16_zmm_regs for the full 512 bits of the second 16 bit registers.

This makes it simple to move data in and out of the xsave region,
but would be a nightmare for a hypothetical TCG implementation and
leads to a proliferation of [XYZ]MM_[BWLSQD] macros.  Instead,
this patch marshals data manually from the xsave region to a single
32x512-bit array, simplifying the macro jungle and clarifying which
bits are in which vmstate subsection.

The migration format is unaffected.

Paolo Bonzini a03c3e90e1 target-i386: use vmstate_offset_sub_array for AVX registers
After the next patch, each vmstate field will extract parts of a larger
(32x512-bit) array, so we cannot check the vmstate field against the
type of the array.

While changing this, change the macros to accept the index of the first
element (which will not be 0 for Hi16_ZMM_REGS) instead of the number
of elements (which is always CPU_NB_REGS).

Kevin Wolf b4168498f6 multiboot: Fix offset of bootloader name
This fixes a bug introduced in commit 5eba5a66 ('Add bootloader name to
multiboot implementation').

The calculation of the bootloader name offset didn't consider space
occupied by module command lines, so some unlucky module got its command
line partially overwritten with a "qemu" string.

Paolo Bonzini 0034a0f239 pc: fix KVM features in pc-1.3 and earlier machine types
Due to a typo, instead of disabling KVM_FEATURE_PV_EOI (bit
6) these machine types are disabling bits 1 and 2, which are
KVM_FEATURE_NOP_IO_DELAY and KVM_FEATURE_MMU_OP.  Not a big deal
because they aren't very important and KVM_FEATURE_MMU_OP is
disabled anyway.  The worst part is actually that KVM_FEATURE_PV_EOI
is remaining enabled.
