2021-07-08hw/misc: add ADM1272 deviceTitus Rwantare4-0/+549
The ADM1272 is a PMBus compliant Hot Swap Controller and Digital Power Monitor by Analog Devices. This commit adds support for interfacing with it, and support for setting and monitoring sensor limits.

Currently the ARM SVE helper code defines locally some utility functions for swapping 16-bit halfwords within 32-bit or 64-bit values and for swapping 32-bit words within 64-bit values, parallel to the byte-swapping bswap16/32/64 functions. We want these also for the ARM MVE code, and they're potentially generally useful for other targets, so move them to bitops.h.

2021-06-16target/arm: Let vfp_access_check() handle late NOCP checksPeter Maydell1-5/+15
In commit a3494d4671797c we reworked the M-profile handling of its checks for when the NOCP exception should be raised because the FPU is disabled, so that (in line with the architecture) the NOCP check is done early over a large range of the encoding space, and takes precedence over UNDEF exceptions. As part of this, we removed the code from full_vfp_access_check() which raised an exception there for M-profile with the FPU disabled, because it was no longer reachable. For MVE, some instructions which are outside the "coprocessor space" region of the encoding space must nonetheless do "is the FPU enabled" checks and possibly raise a NOCP exception. (In particular this covers the MVE-specific low-overhead branch insns LCTP, DLSTP and WLSTP.) To support these insns, reinstate the code in full_vfp_access_check(), so that their trans functions can call vfp_access_check() and get the correct behaviour.

2021-06-16target/arm: Add handling for PSR.ECI/ICIPeter Maydell5-5/+133
On A-profile, PSR bits [15:10][26:25] are always the IT state bits. On M-profile, some of the reserved encodings of the IT state are used to instead indicate partial progress through instructions that were interrupted partway through by an exception and can be resumed. These resumable instructions fall into two categories: (1) load/store multiple instructions, where these bits are called "ICI" and specify the register in the ldm/stm list where execution should resume. (Specifically: LDM, STM, VLDM, VSTM, VLLDM, VLSTM, CLRM, VSCCLRM.) (2) MVE instructions subject to beatwise execution, where these bits are called "ECI" and specify which beats in this and possibly also the following MVE insn have been executed. There are also a few insns (LE, LETP, and BKPT) which do not use the ICI/ECI bits but must leave them alone. Otherwise, we should raise an INVSTATE UsageFault for any attempt to execute an insn with non-zero ICI/ECI bits. So far we have been able to ignore ECI/ICI, because the architecture allows the IMPDEF choice of "always restart load/store multiple from the beginning regardless of ICI state", so the only thing we have been missing is that we don't raise the INVSTATE fault for bad guest code. However, MVE requires that we honour ECI bits and do not rexecute beats of an insn that have already been executed. Add the support in the decoder for handling ECI/ICI: * identify the ECI/ICI case in the CONDEXEC TB flags * when a load/store multiple insn succeeds, it updates the ECI/ICI state (both in DisasContext and in the CPU state), and sets a flag to say that the ECI/ICI state was handled * if we find that the insn we just decoded did not handle the ECI/ICI state, we delete all the code that we just generated for it and instead emit the code to raise the INVFAULT. This allows us to avoid having to update every non-MVE non-LDM/STM insn to make it check for "is ECI/ICI set?". We continue with our existing IMPDEF choice of not caring about the ICI state for the load/store multiples and simply restarting them from the beginning. Because we don't allow interrupts in the middle of an insn, the only way we would see this state is if the guest set ICI manually on return from an exception handler, so it's a corner case which doesn't merit optimisation. ICI update for LDM/STM is simple -- it always zeroes the state. ECI update for MVE beatwise insns will be a little more complex, since the ECI state may include information for the following insn.

It must also be zeroed in various situations when we invalidate FPU context. Update the code which handles the stack frames (exception entry and exit code, VLLDM, and VLSTM) to save/restore VPR.

Currently we provide Hn and H1_n macros for accessing the correct data within arrays of vector elements of size 1, 2 and 4, accounting for host endianness. We don't provide any macros for elements of size 8 because there the host endianness doesn't matter. However, this does result in awkwardness where we need to pass empty arguments to macros, because checkpatch complains about them. The empty argument is a little confusing for humans to read as well.

In commit da6d674e509f0939b we split the NVIC code out from the GIC. This allowed us to specify the NVIC's default value for the num-irq property (64) in the usual way in its property list, and we deleted the previous hack where we updated the value in the state struct in the instance init function. Remove a stale comment about that hack which we forgot to delete at that time.

2021-06-15hw/intc/arm_gicv3_cpuif: Tolerate spurious EOIR writesJean-Philippe Brucker1-1/+4
Commit 382c7160d1cd ("hw/intc/arm_gicv3_cpuif: Fix EOIR write access check logic") added an assert_not_reached() if the guest writes the EOIR register while no interrupt is active. It turns out some software does this: EDK2, in GicV3ExitBootServicesEvent(), unconditionally write EOIR for all interrupts that it manages. This now causes QEMU to abort when running UEFI on a VM with GICv3. Although it is UNPREDICTABLE behavior and EDK2 does need fixing, the punishment seems a little harsh, especially since icc_eoir_write() already tolerates writes of nonexistent interrupt numbers. Display a guest error and tolerate spurious EOIR writes.
