(see issue 2548 for the repro case). This happens because the guest attempts USB_TOKEN_SETUP to an endpoint other than 0, which is not valid. The controller code doesn't catch this guest error, so instead we hit the assertion in the USB core code. Catch the case of SETUP to non-zero endpoint, and treat it as a fatal error in the TD, in the same way we do for an invalid PID value in the TD. This is the UHCI equivalent of the same bug in OHCI that we fixed in commit 3c3c233677 ("hw/usb/hcd-ohci: Fix #1510, #303: pid not IN or OUT"). This bug has been tracked as CVE-2024-8354.

So, building with passt enabled requires GIO to be available. If we enable passt and disable gio the build fails during linkage with undefined reference errors: /usr/bin/ld: libsystem.a.p/net_passt.c.o: in function `net_passt_start_daemon': net/passt.c:250: undefined reference to `g_subprocess_launcher_new' /usr/bin/ld: net/passt.c:251: undefined reference to `g_subprocess_launcher_take_fd' /usr/bin/ld: net/passt.c:253: undefined reference to `g_subprocess_launcher_spawnv' /usr/bin/ld: net/passt.c:256: undefined reference to `g_object_unref' /usr/bin/ld: net/passt.c:263: undefined reference to `g_subprocess_wait' /usr/bin/ld: net/passt.c:268: undefined reference to `g_subprocess_get_if_exited' /usr/bin/ld: libsystem.a.p/net_passt.c.o: in function `glib_autoptr_clear_GSubprocess': /usr/include/glib-2.0/gio/gio-autocleanups.h:132: undefined reference to `g_object_unref' /usr/bin/ld: libsystem.a.p/net_passt.c.o: in function `net_passt_start_daemon': net/passt.c:269: undefined reference to `g_subprocess_get_exit_status' Fix this by adding an explicit weson dependency on GIO for the passt option. The existing dependency on linux is kept because passt is only available on this OS.

ID_AA64PFR2_EL1 encoding as reserved (with the required RAZ behaviour for unassigned system registers in the ID register encoding space). Newer architecture versions start to define fields in this ID register, so define the appropriate constants and implement it as an ID register backed by a field in cpu->isar. Since none of our CPUs set that isar field to non-zero, there is no behavioural change here (other than the name exposed to the user via the gdbstub), but this paves the way for implementing the new features that use fields in this register. The fields here are the ones documented in rev L.b of the Arm ARM.

That in turn means that tests of cpu_isar_feature(aa64_something, cpu) will return true. Until now we have had a design policy that you shouldn't check an aa64_ feature unless you know that the CPU has AArch64; but this is quite fragile as it's easy to forget and only causes a problem in the corner case where AArch64 was turned off. In particular, when we extend the ability to disable AArch64 from only KVM to also TCG there are many more aa64 feature check points which we would otherwise have to audit for whether they needed to be guarded with a check on ARM_FEATURE_AARCH64. Instead, make the CPU realize function zero out all the 64-bit ID registers if a TCG CPU doesn't have AArch64; this will make aa64_ feature tests generally return false. We only do this for TCG because only TCG really needs it, and for KVM it might be confusing to have QEMU's idea of the ID registers be different from KVM's.

The tolerance applies to a given cpreg kvm index, and can be of different types: a) mismatch in cpreg indexes - ToleranceNotOnBothEnds (cpreg index is allowed to be only present on one end) - ToleranceOnlySrcTestValue (cpreg index is allowed to be only present in source if its value @mask field matches @value) b) mismatch in cpreg values - ToleranceDiffInMask (value differences are allowed only within a mask) - ToleranceFieldLT (incoming field value must be less than a given value) - ToleranceFieldGT (incoming field value must be greater than a given value) A QLIST of such tolerances can be populated using a new helper: arm_register_cpreg_mig_tolerance() and arm_cpu_match_cpreg_mig_tolerance() allows to check whether a tolerance exists for a given kvm index and its criterion is matched. callers for those helpers will be introduced in subsequent patches. Only registration of migration tolerances related to cpreg index mismatch is currently allowed.
