There is no need to re-set these 3 features already
implied by the call to aarch64_a15_initfn.
Backports commit 0b33968e7f4cf998f678b2d1a5be3d6f3f3513d8 from qemu
There is no need to re-set these 9 features already
implied by the call to aarch64_a57_initfn.
Backports commit 156a7065365578deb3d63c2b5b69a4b5999a8fcc from qemu
Leave ARM_CP_SVE, removing ARM_CP_FPU; the sve_access_check
produced by the flag already includes fp_access_check. If
we also check ARM_CP_FPU the double fp_access_check asserts.
Backports commit 11d7870b1b4d038d7beb827f3afa72e284701351 from qemu
We already check for the same condition within the normal integer
sdiv and sdiv64 helpers. Use a slightly different formation that
does not require deducing the expression type.
Backports commit 7e8fafbfd0537937ba8fb366a90ea6548cc31576 from qemu
Since kernel commit a86bd139f2 (arm64: arch_timer: Enable CNTVCT_EL0
trap..), released in kernel version v4.12, user-space has been able
to read these system registers. As we can't use QEMUTimer's in
linux-user mode we just directly call cpu_get_clock().
Backports commit 26c4a83bd4707797868174332a540f7d61288d15 from qemu
We've already added the helpers with an SVE patch, all that remains
is to wire up the aa64 and aa32 translators. Enable the feature
within -cpu max for CONFIG_USER_ONLY.
Backports commit 26c470a7bb4233454137de1062341ad48947f252 from qemu
Enhance the existing helpers to support SVE, which takes the
index from each 128-bit segment. The change has no effect
for AdvSIMD, since there is only one such segment.
Backports commit 18fc24057815bf3d956cfab892a2bc2344bd1dcb from qemu
For aa64 advsimd, we had been passing the pre-indexed vector.
However, sve applies the index to each 128-bit segment, so we
need to pass in the index separately.
For aa32 advsimd, the fp32 operation always has index 0, but
we failed to interpret the fp16 index correctly.
Backports commit 2cc99919a81a62589a4a6b0f365eabfead1db1a7 from qemu
It calls cpu_loop_exit in system emulation mode (and should never be
called in user emulation mode).
Backports commit 50b3de6e5cd464dcc20e3a48f5a09e0299a184ac from qemu
We need to terminate the translation block after STGI so that pending
interrupts can be injected.
This fixes pending NMI injection for Jailhouse which uses "stgi; clgi"
to open a brief injection window.
Backports commit df2518aa587a0157bbfbc635fe47295629d9914a from qemu
Check for SVM interception prior to injecting an NMI. Tested via the
Jailhouse hypervisor.
Backports commit 02f7fd25a446a220905c2e5cb0fc3655d7f63b29 from qemu
The implementation of these two instructions was swapped.
At the same time, unify the setup of eflags for the insn group.
Backports commit 13672386a93fef64cfd33bd72fbf3d80f2c00e94 from qemu
Offset can be larger than 16 bit from nanoMIPS,
and immediate field can be larger than 16 bits as well.
