2021-09-01arm: Move system PPB container handling to armv7mPeter Maydell
Instead of having the NVIC device provide a single sysbus memory region covering the whole of the "System PPB" space, which implements the default behaviour for unimplemented ranges and provides the NS alias window to the sysregs as well as the main sysreg MR, move this handling to the container armv7m device. The NVIC now provides a single memory region which just implements the system registers. This consolidates all the handling of "map various devices in the PPB" into the armv7m container where it belongs.

2021-09-01arm: Move systick device creation from NVIC to ARMv7M objectPeter Maydell
There's no particular reason why the NVIC should be owning the SysTick device objects; move them into the ARMv7M container object instead, as part of consolidating the "create the devices which are built into an M-profile CPU and map them into their architected locations in the address space" work into one place. This involves temporarily creating a duplicate copy of the nvic_sysreg_ns_ops struct and its read/write functions (renamed as v7m_sysreg_ns_*), but we will delete the NVIC's copy of this code in a subsequent patch.

2021-09-01hw/intc/arm_gicv3: Replace mis-used MEMTX_* constants by booleansPhilippe Mathieu-Daudé
Quoting Peter Maydell: These MEMTX_* aren't from the memory transaction API functions; they're just being used by gicd_readl() and friends as a way to indicate a success/failure so that the actual MemoryRegionOps read/write fns like gicv3_dist_read() can log a guest error. Arguably this is a bit of a misuse of the MEMTX_* constants and perhaps we should have gicd_readl etc return a bool instead. Follow his suggestion and replace the MEMTX_* constants by boolean values, simplifying a bit the gicv3_dist_read() / gicv3_dist_write() handlers.

2021-09-01hw/intc/sifive_clint: Fix muldiv64 overflow in sifive_clint_write_timecmp()David Hoppenbrouwers
`muldiv64` would overflow in cases where the final 96-bit value does not fit in a `uint64_t`. This would result in small values that cause an interrupt to be triggered much sooner than intended. The overflow can be detected in most cases by checking if the new value is smaller than the previous value. If the final result is larger than `diff` it is either correct or it doesn't matter as it is effectively infinite anyways. `next` is an `uint64_t` value, but `timer_mod` takes an `int64_t`. This resulted in high values such as `UINT64_MAX` being converted to `-1`, which caused an immediate timer interrupt. By limiting `next` to `INT64_MAX` no overflow will happen while the timer will still be effectively set to "infinitely" far in the future.

2021-07-09hw/intc/arm_gicv3_cpuif: Fix virtual irq number check in icv_[dir|eoir]_writeRicardo Koller
icv_eoir_write() and icv_dir_write() ignore invalid virtual IRQ numbers (like LPIs). The issue is that these functions check against the number of implemented IRQs (QEMU's default is num_irq=288) which can be lower than the maximum virtual IRQ number (1020 - 1). The consequence is that if a hypervisor creates an LR for an IRQ between 288 and 1020, then the guest is unable to deactivate the resulting IRQ. Note that other functions that deal with large IRQ numbers, like icv_iar_read, check against 1020 and not against num_irq. Fix the checks by using GICV3_MAXIRQ (1020) instead of the number of implemented IRQs.

2021-06-15hw/intc/arm_gicv3_cpuif: Tolerate spurious EOIR writesJean-Philippe Brucker
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.

2021-05-25hw/intc/arm_gicv3_cpuif: Fix EOIR write access check logicPeter Maydell
In icc_eoir_write() we assume that we can identify the group of the IRQ being completed based purely on which register is being written to and the current CPU state, and that "CPU state matches group indicated by register" is the only necessary access check. This isn't correct: if the CPU is not in Secure state then EOIR1 will only complete Group 1 NS IRQs, but if the CPU is in EL3 it can complete both Group 1 S and Group 1 NS IRQs. (The pseudocode ICC_EOIR1_EL1 makes this clear.) We were also missing the logic to prevent EOIR0 writes completing G0 IRQs when they should not. Rearrange the logic to first identify the group of the current highest priority interrupt and then look at whether we should complete it or ignore the access based on which register was accessed and the state of the CPU. The resulting behavioural change is: * EL3 can now complete G1NS interrupts * G0 interrupt completion is now ignored if the GIC and the CPU have the security extension enabled and the CPU is not secure Reported-by: Chan Kim <ckim@etri.re.kr> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20210510150016.24910-1-peter.maydell@linaro.org

They can't be plugged with -device / device_add, except for xlnx,zynqmp-pmu-soc, and I doubt that one actually works. They *can* be used with -device / device_add to request help. Usability is poor, though: you have to double the comma, like this: $ qemu-system-x86_64 -device SUNW,,fdtwo,help Trap for the unwary. The fact that this was broken in device-introspect-test for more than six years until commit e27bd49876 fixed it demonstrates that "the unwary" includes seasoned developers. One QOM type name contains ' ': "ICH9 SMB". Because having to remember just one way to quote would be too easy. Rename the "SUNW,FOO types to "sun-FOO". Summarily replace ',' and ' ' by '-' in the other type names.

2021-03-06KVM: x86: deprecate -M kernel-irqchip=off except for -M isapcPaolo Bonzini
The userspace local APIC is basically untested and does not support many features such as TSC deadline timer, x2APIC or PV spinlocks. On the other hand, the PIT and IOAPIC are okay as they are not tied to the processor and are tested with -M kernel-irqchip=split. Therefore, deprecate the local APIC and, with it, limit -M kernel-irqchip=off to the ISA PC machine type, which does not have a local APIC at all.
