HMP command "change vnc" can take the password as argument, or prompt
for it:
(qemu) change vnc password 123
(qemu) change vnc password
Password: ***
(qemu)
This regressed in commit cfb5387a1d "hmp: remove "change vnc TARGET"
command", v6.0.0.
(qemu) change vnc passwd 123
If you'd rather delete "change vnc", go ahead and post a patch.

If a legacy 'drive' argument is passed to the controller we cannot
assume that '1' will be a free NSID, as the subsys might already
have attached a namespace to this NSID. So select the first free
one.

This patch adds support for PCIe Root Complex Event Collector
(RCEC) emulation. Further, if a RCiEP supports AER capability
then a mapping is created for that RCiEP in the RCEC's
endpoint association capability.

Hi All,
This is a first attempt to add PCIe Root Complex Event Collector emulation
support to Qemu. This patch is created on Qemu commit:88afdc92b6 and tested
using Qemu Risc V virt machine and the PCIe aer error injection module in the
Linux kernel(v 5.14).
Thanks,

Due to an incorrect definition of helper,

The PL031 currently is not able to report guest RTC change to the QMP

to qapi_event_send_rtc_change() when the Load Register is written. The

So, its compatibility tuning is meaningless.

Is there a rule for when we should set is_jmp to DISAS_UPDATE_NOCHAIN,
when we should set it to DISAS_UPDATE_EXIT

Although the doc comment says "Called within RCU critical section" the
address_space_read() function takes the RCU read lock itself. There is
no need for the caller to hold an RCU read lock.

CPUID leaf 0x14 subleaf 0x0 and 0x1 enumerate the resource and
capability of Intel PT.
Introduce FeatureWord FEAT_14_0_EBX, FEAT_14_1_EAX and FEAT_14_1_EBX,
and complete FEAT_14_0_ECX. Thus all the features of Intel PT can be
expanded when "-cpu host/max" and can be configured in named CPU model.
Initial Intel PT support was added by making it as fixed feature set as
ICX's capabilities, which allowed different CPU model with PT enabled
live migration on ICX host. However, it breaks the PT exposure/working
on SPR machine. Because SPR has less PT capabilities regrading
CPUID(0x14,1):EBX[15:0]
KVM only allows userspace to access legal number of MSR_IA32_RTIT_ADDRn,
which is enumrated by guest's CPUID(0x14,0x1):EAX[2:0], i.e.,
env->features[FEAT_14_1_EAX] & INTEL_PT_ADDR_RANGES_NUM_MASK

commit e37a5c7fa459 ("i386: Add Intel Processor Trace feature support")
added the support of Intel PT by making CPUID[14] of PT as fixed feature
set (from ICX) for any CPU model on any host.
This truly breaks the PT exposing on Intel SPR platform because SPR has
less supported bitmap CPUID(0x14,1)
