Ard Biesheuvel [Tue, 7 Jul 2020 10:07:11 +0000 (12:07 +0200)]
arm: qemu: override flash accessors to use virtualizable instructions

Some instructions in the ARM ISA have multiple output registers, such
as ldrd/ldp (load pair), where two registers are loaded from memory,
but also ldr with indexing, where the memory base register is incremented
as well when the value is loaded to the destination register.

MMIO emulation under KVM is based on using the architecturally defined
syndrome information that is provided when an exception is taken to the
hypervisor. This syndrome information describes whether the instruction
that triggered the exception is a load or a store, what the faulting
address was, and which register was the destination register.

This syndrome information can only describe one destination register, and
when the trapping instruction is one with multiple outputs, KVM throws an
error like

  kvm [615929]: Data abort outside memslots with no valid syndrome info

on the host and kills the QEMU process with the following error:

  U-Boot 2020.07-rc3-00208-g88bd5b179360-dirty (Jun 06 2020 - 11:59:22 +0200)

  PSR=200001d3 --C- A svc32
  QEMU: Terminated

This means that, in order to run U-Boot in QEMU under KVM, we need to
avoid such instructions when accessing emulated devices. For the flash
in particular, which is a hybrid between a ROM (backed by a read-only
KVM memslot) when in array mode, and an emulated MMIO device (when in
write mode), we need to take care to only use instructions that KVM can
deal with when they trap.

So override the flash read accessors that are used when running on QEMU
under KVM. Note that the the 64-bit wide read and write accessors have
been omitted: they are never used when running under QEMU given that it
does not emulate CFI flash that supports it.

We will shortly enable support for running under KVM, but the GRUB
hack (which disables all caches without doing cache cleaning by VA
during ExitBootServices()) is likely to cause more problems than it

QEMU's mach-virt machine only supports selecting CPU models that
implement the virtualization extensions, and are therefore guaranteed
to support LPAE as well.

Initially, QEMU would not allow emulating these CPUs running in HYP
mode (or EL2, for AArch64), but today, it also contains a complete
implementation of the virtualization extensions themselves.

This means we could be running U-Boot in HYP mode, in which case the
LPAE long descriptor page table format is the only format that is
supported. If we are not running in HYP mode, we can use either.

So let's enable CONFIG_ARMV7_LPAE for qemu_arm_defconfig so that we
get the best support for running with the MMU and caches enabled at
any privilege level.

Spin tables are broken with bootefi. This is because - in contrast to
the booti call chain - there is no call to smp_kick_all_cpus(). Due to
this missing call the secondary CPUs are never released from their "wait
for interrupt state", see secondary_boot_func() in lowlevel.S.

Originally, this "wait for interrupt" is there to make sure, the spin
table is cleared before the secondary cores read it for the first time.
But the boot flow for the layerscape architecture is different from
that. The CPUs are release from their BootROM _after_ U-Boot's
spin-table is cleared, see fsl_layerscape_wake_seconday_cores() in mp.c.
Thus, there is no need to wait for this interrupt and no need for
kicking all cores on cpu_release. An atomic 64bit write to the
spin-table and a "sev" is sufficient.
