Frederic Barrat d5aa9e7904 pnv/xive2: Don't overwrite PC registers when writing TCTXT registers
When writing a register from the TCTXT memory region (4th page within
the IC BAR), we were overwriting the Presentation Controller (PC)
register at the same offset. It looks like a silly cut and paste
error.

We were somehow lucky: the TCTXT registers being touched are
TCTXT_ENx/_SET/_RESET to enable physical threads and the PC registers
at the same offset are either not used by our model or the update was
harmless.

Found through code inspection.

Víctor Colombo dd657a35b4 target/ppc: Rename sfprf to sfifprf where it's also used as set fi flag
The bit FI fix used the sfprf flag as a flag for the set_fi parameter
in do_float_check_status where applicable. Now, this patch rename this
flag to sfifprf to state this dual usage.

Víctor Colombo c582a1dbc8 target/ppc: Fix FPSCR.FI changing in float_overflow_excp()
This patch fixes another not-so-clear situation in Power ISA
regarding the inexact bits in FPSCR. The ISA states that:

"""
When Overflow Exception is disabled (OE=0) and an
Overflow Exception occurs, the following actions are
taken:
...
2. Inexact Exception is set
XX <- 1
...
FI is set to 1
...
"""

However, when tested on a Power 9 hardware, some instructions that
trigger an OX don't set the FI bit:

xvcvdpsp(0x4050533fcdb7b95ff8d561c40bf90996) = FI: CLEARED -> CLEARED
xvnmsubmsp(0xf3c0c1fc8f3230, 0xbeaab9c5) = FI: CLEARED -> CLEARED
(just a few examples. Other instructions are also affected)

The root cause for this seems to be that only instructions that list
the bit FI in the "Special Registers Altered" should modify it.

QEMU is, today, not working like the hardware:

xvcvdpsp(0x4050533fcdb7b95ff8d561c40bf90996) = FI: CLEARED -> SET
xvnmsubmsp(0xf3c0c1fc8f3230, 0xbeaab9c5) = FI: CLEARED -> SET

(all tests assume FI is cleared beforehand)

Fix this by making float_overflow_excp() return float_flag_inexact
if it should update the inexact flags.

Víctor Colombo 3278677f6a target/ppc: Fix FPSCR.FI bit being cleared when it shouldn't
According to Power ISA, the FI bit in FPSCR is non-sticky.
This means that if an instruction is said to modify the FI bit, then
it should be set or cleared depending on the result of the
instruction. Otherwise, it should be kept as was before.

However, the following inconsistency was found when comparing results
from the hardware (tested on both a Power 9 processor and in
Power 10 Mambo):

(FI bit is set before the execution of the instruction)
Hardware: xscmpeqdp(0xff..ff, 0xff..ff) = FI: SET -> SET
QEMU: xscmpeqdp(0xff..ff, 0xff..ff) = FI: SET -> CLEARED

As the FI bit is non-sticky, and xscmpeqdp does not list it as a field
that is changed by the instruction, it should not be changed after its
execution.
This is happening to multiple instructions in the vsx implementations.

If the ISA does not list the FI bit as altered for a particular
instruction, then it should be kept as it was before the instruction.

QEMU is not following this behavior. Affected instructions include:
- xv* (all vsx-vector instructions);
- xscmp*, xsmax*, xsmin*;
- xstdivdp and similars;
(to identify the affected instructions, just search in the ISA for
 the instructions that does not list FI in "Special Registers Altered")

Most instructions use the function do_float_check_status() to commit
changes in the inexact flag. So the fix is to add a parameter to it
that will control if the bit FI should be changed or not.
All users of do_float_check_status() are then modified to provide this
argument, controlling if that specific instruction changes bit FI or
not.
Some macro helpers are responsible for both instructions that change
and instructions that aren't suposed to change FI. This seems to always
overlap with the sfprf flag. So, reuse this flag for this purpose when
applicable.

Leandro Lupori 4ddc104689 target/ppc: Fix tlbie
Commit 74c4912f09 changed check_tlb_flush() to use
tlb_flush_all_cpus_synced() instead of calling tlb_flush() on each
CPU. However, as side effect of this, a CPU executing a ptesync
after a tlbie will have its TLB flushed only after exiting its
current Translation Block (TB).

This causes memory accesses to invalid pages to succeed, if they
happen to be on the same TB as the ptesync.

To fix this, use tlb_flush_all_cpus() instead, that immediately
flushes the TLB of the CPU executing the ptesync instruction.

Alexey Kardashevskiy 5bb55f3e3b spapr: Use address from elf parser for kernel address
tl;dr: This allows Big Endian zImage booting via -kernel + x-vof=on.

QEMU loads the kernel at 0x400000 by default which works most of
the time as Linux kernels are relocatable, 64bit and compiled with "-pie"
(position independent code). This works for a little endian zImage too.

However a big endian zImage is compiled without -pie, is 32bit, linked to
0x4000000 so current QEMU ends up loading it at
0x4400000 but keeps spapr->kernel_addr unchanged so booting fails.

This uses the kernel address returned from load_elf().
If the default kernel_addr is used, there is no change in behavior (as
translate_kernel_address() takes care of this), which is:
LE/BE vmlinux and LE zImage boot, BE zImage does not.
If the VM created with "-machine kernel-addr=0,x-vof=on", then QEMU
prints a warning and BE zImage boots.

Note #1: SLOF (x-vof=off) still cannot boot a big endian zImage as
SLOF enables MSR_SF for everything loaded by QEMU and this leads to early
crash of 32bit zImage.

Note #2: BE/LE vmlinux images set MSR_SF in early boot so these just work;
a LE zImage restores MSR_SF after every CI call and we are lucky enough
not to crash before the first CI call.

Paolo Bonzini f73eb9484b pseries: allow setting stdout-path even on machines with a VGA
-machine graphics=off is the usual way to tell the firmware or the OS that the
user wants a serial console.  The pseries machine however does not support
this, and never adds the stdout-path node to the device tree if a VGA device
is provided.  This is in addition to the other magic behavior of VGA devices,
which is to add a keyboard and mouse to the default USB bus.

Split spapr->has_graphics in two variables so that the two behaviors can be
separated: the USB devices remains the same, but the stdout-path is added
even with "-device VGA -machine graphics=off".

Vitaly Kuznetsov 3aae0854b2 i386: Hyper-V Direct TLB flush hypercall
Hyper-V TLFS allows for L0 and L1 hypervisors to collaborate on L2's
TLB flush hypercalls handling. With the correct setup, L2's TLB flush
hypercalls can be handled by L0 directly, without the need to exit to
L1.

Vitaly Kuznetsov aa6bb5fad5 i386: Hyper-V Support extended GVA ranges for TLB flush hypercalls
KVM kind of supported "extended GVA ranges" (up to 4095 additional GFNs
per hypercall) since the implementation of Hyper-V PV TLB flush feature
(Linux-4.18) as regardless of the request, full TLB flush was always
performed. "Extended GVA ranges for TLB flush hypercalls" feature bit
wasn't exposed then. Now, as KVM gains support for fine-grained TLB
flush handling, exposing this feature starts making sense.

Vitaly Kuznetsov 9411e8b6fa i386: Hyper-V XMM fast hypercall input feature
Hyper-V specification allows to pass parameters for certain hypercalls
using XMM registers ("XMM Fast Hypercall Input"). When the feature is
in use, it allows for faster hypercalls processing as KVM can avoid
reading guest's memory.

KVM supports the feature since v5.14.

Rename HV_HYPERCALL_{PARAMS_XMM_AVAILABLE -> XMM_INPUT_AVAILABLE} to
comply with KVM.

Vitaly Kuznetsov 7110fe56c1 i386: Use hv_build_cpuid_leaf() for HV_CPUID_NESTED_FEATURES
Previously, HV_CPUID_NESTED_FEATURES.EAX CPUID leaf was handled differently
as it was only used to encode the supported eVMCS version range. In fact,
there are also feature (e.g. Enlightened MSR-Bitmap) bits there. In
preparation to adding these features, move HV_CPUID_NESTED_FEATURES leaf
handling to hv_build_cpuid_leaf() and drop now-unneeded 'hyperv_nested'.

No functional change intended.

Lev Kujawski 758c925ee0 ide_ioport_read: Return lower octet of data register instead of 0xFF
Prior to this patch, the pre-GRUB Solaris x86 bootloader would fail to
load on QEMU with the following screen output:

SunOS Secondary Boot version 3.00

prom_panic: Could not mount filesystem.
Entering boot debugger:
[136419]: _

This occurs because the bootloader issues an ATA IDENTIFY DEVICE
command, and then reads the resulting 256 words of parameter
information using inb rather than the correct inw. As the previous
behavior of QEMU was to return 0xFF and not advance the drive's sector
buffer, DRQ would never be cleared and the bootloader would be blocked
from selecting a secondary ATA device, such as an optical drive.

Maciej S. Szmigiero 267b5e7e37 target/i386/kvm: Fix disabling MPX on "-cpu host" with MPX-capable host
Since KVM commit 5f76f6f5ff96 ("KVM: nVMX: Do not expose MPX VMX controls when guest MPX disabled")
it is not possible to disable MPX on a "-cpu host" just by adding "-mpx"
there if the host CPU does indeed support MPX.
QEMU will fail to set MSR_IA32_VMX_TRUE_{EXIT,ENTRY}_CTLS MSRs in this case
and so trigger an assertion failure.

Instead, besides "-mpx" one has to explicitly add also
"-vmx-exit-clear-bndcfgs" and "-vmx-entry-load-bndcfgs" to QEMU command
line to make it work, which is a bit convoluted.

Make the MPX-related bits in FEAT_VMX_{EXIT,ENTRY}_CTLS dependent on MPX
being actually enabled so such workarounds are no longer necessary.

Paolo Bonzini 900fa208f5 thread-pool: replace semaphore with condition variable
Since commit f9fc8932b1 ("thread-posix: remove the posix semaphore
support", 2022-04-06) QemuSemaphore has its own mutex and condition
variable; this adds unnecessary overhead on I/O with small block sizes.

Check the QTAILQ directly instead of adding the indirection of a
semaphore's count.  Using a semaphore has not been necessary since
qemu_cond_timedwait was introduced; the new code has to be careful about
spurious wakeups but it is simpler, for example thread_pool_cancel does
not have to worry about synchronizing the semaphore count with the number
of elements of pool->request_list.

Note that the return value of qemu_cond_timedwait (0 for timeout, 1 for
signal or spurious wakeup) is different from that of qemu_sem_timedwait
(-1 for timeout, 0 for success).

Paolo Bonzini 3c7b72ddca thread-pool: optimize scheduling of completion bottom half
The completion bottom half was scheduled within the pool->lock
critical section.  That actually results in worse performance,
because the worker thread can run its own small critical section
and go to sleep before the bottom half starts running.

Note that this simple change does not produce an improvement without
changing the thread pool QemuSemaphore to a condition variable.
