由 Hugo Landau 提交于
Some register blocks of the ast2500 are protected by protection key registers which require the right magic value to be written to those registers to allow those registers to be mutated. Register manuals indicate that writing the correct magic value to these registers should cause subsequent reads from those values to return 1, and writing any other value should cause subsequent reads to return 0. Previously, qemu implemented these registers incorrectly: the registers were handled as simple memory, meaning that writing some value x to a protection key register would result in subsequent reads from that register returning the same value x. The protection was implemented by ensuring that the current value of that register equaled the magic value. This modifies qemu to have the correct behaviour: attempts to write to a ast2500 protection register results in a transition to 1 or 0 depending on whether the written value is the correct magic. The protection logic is updated to ensure that the value of the register is nonzero. This bug caused deadlocks with u-boot HEAD: when u-boot is done with a protectable register block, it attempts to lock it by writing the bitwise inverse of the correct magic value, and then spinning forever until the register reads as zero. Since qemu implemented writes to these registers as ordinary memory writes, writing the inverse of the magic value resulted in subsequent reads returning that value, leading to u-boot spinning forever.

This patch adds a "raspi3" machine type, which can now be selected as the machine to run on by users via the "-M" command line option to QEMU. The machine type does *not* ignore memory transaction failures so we likely need to add some dummy devices later when people run something more complicated than what I'm using for testing.

The register definitions for VMIDR and VMPIDR have separate reginfo structs for the AArch32 and AArch64 registers. However the 32-bit versions are wrong: * they use offsetof instead of offsetoflow32 to mark where the 32-bit value lives in the uint64_t CPU state field * they don't mark themselves as ARM_CP_ALIAS In particular this means that if you try to use an Arm guest CPU which enables EL2 on a big-endian host it will assert at reset: target/arm/cpu.c:114: cp_reg_check_reset: Assertion `oldvalue == newvalue' failed. because the reset of the 32-bit register writes to the top half of the uint64_t. Correct the errors in the structures.

This is a little bit of a departure from softfloat's original approach as we skip the estimate step in favour of a straight iteration. There is a minor optimisation to avoid calculating more bits of precision than we need however this still brings a performance drop, especially for float64 operations.
