it shows an error message like this:
virtio_gpu_create_mapping_iov: nr_entries is too big (83886080 > 16384)
which indicates that this value has not been properly byte-swapped.
And indeed, the virtio_gpu_create_blob_bswap() function (that should

virtio-gpu device is now also working with blob=true on s390x hosts.

When we do a translation in Secure state, the NSTable bits in table
descriptors may downgrade us to NonSecure; we update ptw->in_secure
and ptw->in_space accordingly. We guard that check correctly with a
conditional that means it's only applied for Secure stage 1
translations. However, later on in get_phys_addr_lpae() we fold the
effects of the NSTable bits into the final descriptor attributes
bits, and there we do it unconditionally regardless of the CPU state.
That means that in Realm state (where in_secure is false) we will set
bit 5 in attrs, and later use it to decide to output to non-secure
space.
We don't in fact need to do this folding in at all any more (since
commit 2f1ff4e7b9): if an NSTable bit was set then we have
already set ptw->in_space to ARMSS_NonSecure, and in that situation
we don't look at attrs bit 5. The only thing we still need to deal
with is the real NS bit in the final descriptor word, so we can just
drop the code that ORed in the NSTable bit.

arm_hcr_el2_eff_secstate() takes a bool secure, which it uses to
determine whether EL2 is enabled in the current security state.
With the advent of FEAT_RME this is no longer sufficient, because
EL2 can be enabled for Secure state but not for Root, and both
of those will pass 'secure == true' in the callsites in ptw.c.
As it happens in all of our callsites in ptw.c we either avoid making
the call or else avoid using the returned value if we're doing a
translation for Root, so this is not a behaviour change even if the
experimental FEAT_RME is enabled. But it is less confusing in the
ptw.c code if we avoid the use of a bool secure that duplicates some
of the information in the ArmSecuritySpace argument.
Make arm_hcr_el2_eff_secstate() take an ARMSecuritySpace argument
instead. Because we always want to know the HCR_EL2 for the
security state defined by the current effective value of
SCR_EL3.{NSE,NS}, it makes no sense to pass ARMSS_Root here,
and we assert that callers don't do that.
To avoid the assert(), we thus push the call to
arm_hcr_el2_eff_secstate() down into the cases in
regime_translation_disabled() that need it, rather than calling the
function and ignoring the result for the Root space translations.
All other calls to this function in ptw.c are already in places
where we have confirmed that the mmu_idx is a stage 2 translation
or that the regime EL is not 3.

Instead of taking advantage of that freedom, consistently

In S1_ptw_translate() we set up the ARMMMUFaultInfo if the attempt to

This used to only be possible if we are doing a stage 2 ptw for that

fi->s1ptw to true. However, with FEAT_RME it is also possible for
the lookup of the page descriptor address to fail because of a
Granule Protection Check fault. These should not be reported as
stage 2, otherwise arm_deliver_fault() will incorrectly set
HPFAR_EL2. Similarly the s1ptw bit should only be set for stage 2
faults on stage 1 translation table walks, i.e. not for GPC faults.
Add a comment to the the other place where we might detect a

Implement nRF51 DETECT signal in the GPIO peripheral.
The reference manual makes mention of a per-pin DETECT signal, but these
are not exposed to the user. See https://devzone.nordicsemi.com/f/nordic-q-a/39858/gpio-per-pin-detect-signal-available
for more information. Currently, I don't see a reason to model these.
