This helper is also useful for other iommu devices (virtio-iommu, SMMUv3) to make sure IOMMU UNMAP notifiers only are called with power of 2 range sizes. Let's move this latter into dma-helpers.c and rename it into dma_aligned_pow2_mask(). Also rewrite the helper so that it accomodates UINT64_MAX values for the size mask and max mask. It now returns a mask instead of a size. Change the caller.

It searches for a list of consecutive descriptors whichs are flagged as ready for processing and transmits their payloads accordingly. The controller stops processing once it finds a descriptor that is not marked ready. While the above behaviour works in most situations, it is not the same as the actual EMAC in hardware. Actual hardware uses the TX_CUR_DESC register value to keep track of the last position in the transmit queue and continues processing from that position when software triggers the start of DMA processing. The currently emulated behaviour can lead to packet loss on transmit when software fills the transmit queue with ready descriptors that overlap the tail of the circular list. This commit modifies the emulated EMAC for sun8i such that it processes the transmit queue using the TX_CUR_DESC register in the same way as hardware.

If that bound is lower than the highest possible GPA for the machine, then QEMU will error out. However, the IPA is set to 40 when the highest GPA is less than or equal to 40, even when KVM may support an IPA limit as low as 32. This means KVM may fail the VM creation unnecessarily. Additionally, 40 is selected with the value 0, which means use the default, and that gets around a check in some versions of KVM, causing a difficult to debug fail. Always use the IPA size that corresponds to the highest possible GPA, unless it's lower than 32, in which case use 32. Also, we must still use 0 when KVM only supports the legacy fixed 40 bit IPA.

This module is mainly used to configure PWM fans. It has just enough functionality to make the PWM fan kernel module work. The module takes two input, the max_rpm of a fan (modifiable via QMP) and duty cycle (a GPIO from the PWM module.) The actual measured RPM is equal to max_rpm * duty_cycle / NPCM7XX_PWM_MAX_DUTY. The RPM is measured as a counter compared to a prescaled input clock. The kernel driver reads this counter and report to user space.

This is a problem, because at the moment the core memory system does not implement the support for handling unaligned accesses by doing a series of aligned accesses and combining them (system/memory.c:access_with_adjusted_size() has a TODO comment noting this). Fortunately raven_io_read() and raven_io_write() will correctly deal with the case of being passed an unaligned address, so we can fix the missing unaligned access support by setting .impl.unaligned in the MemoryRegionOps struct.

We implemented the timer itself in the CPU model, but never wired up its IRQ line to the GIC. Wire up the IRQ line (this is always safe whether the CPU has the interrupt or not, since it always creates the outbound IRQ line). Report it to the guest via dtb and ACPI if the CPU has the feature. The DTB binding is documented in the kernel's Documentation/devicetree/bindings/timer/arm\,arch_timer.yaml and the ACPI table entries are documented in the ACPI specification version 6.3 or later. Because the IRQ line ACPI binding is new in 6.3, we need to bump the FADT table rev to show that we might be using 6.3 features. Note that exposing this IRQ in the DTB will trigger a bug in EDK2 versions prior to edk2-stable202311, for users who use the virt board with 'virtualization=on' to enable EL2 emulation and are booting an EDK2 guest BIOS, if that EDK2 has assertions enabled. The effect is that EDK2 will assert on bootup: ASSERT [ArmTimerDxe] /home/kraxel/projects/qemu/roms/edk2/ArmVirtPkg/Library/ArmVirtTimerFdtClientLib/ArmVirtTimerFdtClientLib.c(72): PropSize == 36 || PropSize == 48 If you see that assertion you should do one of: * update your EDK2 binaries to edk2-stable202311 or newer * use the 'virt-8.2' versioned machine type * not use 'virtualization=on' (The versions shipped with QEMU itself have the fix.)

When we implemented this we picked which encoding to use based on whether the CPU set ARM_FEATURE_AARCH64. However this isn't right for three cases: * the qemu-system-arm 'max' CPU, which is supposed to be a variant on a Cortex-A57; it ought to use the same encoding the A57 does and which the AArch64 'max' exposes to AArch32 guest code * the Cortex-R52, which is AArch32-only but has the CBAR at the newer encoding (and where we incorrectly are not yet setting ARM_FEATURE_CBAR_RO anyway) * any possible future support for other v8 AArch32 only CPUs, or for supporting "boot the CPU into AArch32 mode" on our existing cores like the A57 etc Make the decision of the encoding be based on whether the CPU implements the ARM_FEATURE_V8 flag instead. This changes the behaviour only for the qemu-system-arm '-cpu max'. We don't expect anybody to be relying on the old behaviour because: * it's not what the real hardware Cortex-A57 does (and that's what our ID register claims we are) * we don't implement the memory-mapped GICv3 support which is the only thing that exists at the peripheral base address pointed to by the register Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20240206132931.38376-2-peter.maydell@linaro.org --- target/arm/helper.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/target/arm/helper.c b/target/arm/helper.c index XXXXXXX..XXXXXXX 100644 --- a/target/arm/helper.c +++ b/target/arm/helper.c @@ -XXX,XX +XXX,XX @@ void register_cp_regs_for_features(ARMCPU *cpu) * AArch64 cores we might need to add a specific feature flag * to indicate cores with "flavour 2" CBAR. */ - if (arm_feature(env, ARM_FEATURE_AARCH64)) { + if (arm_feature(env, ARM_FEATURE_V8)) { /* 32 bit view is [31:18] 0...0 [43:32]. */ uint32_t cbar32 = (extract64(cpu->reset_cbar, 18, 14) << 18) | extract64(cpu->reset_cbar, 32, 12); -- 2.34.1 The Cortex-R52 implements the Configuration Base Address Register (CBAR), as a read-only register.

QEMU has chosen to UNDEF on all of these. However, for the case of accessing SPSR_hyp from hyp mode, it turns out that real hardware permits this, with the same effect as if the guest had directly written to SPSR. Further, there is some guest code out there that assumes it can do this, because it happens to work on hardware: an example Cortex-R52 startup code fragment uses this, and it got copied into various other places, including Zephyr. Zephyr was fixed to not use this: https://github.com/zephyrproject-rtos/zephyr/issues/47330 but other examples are still out there, like the selftest binary for the MPS3-AN536. For convenience of being able to run guest code, permit this UNPREDICTABLE access instead of UNDEFing it.

In many cases we don't really care about the functionality controlled by these registers and a reads-as-written or similar behaviour is sufficient for the moment. For the AN536 the required behaviour is: * A_CFG0 has CPU reset and halt bits - implement as reads-as-written for the moment * A_CFG1 has flash or ATCM address 0 remap handling - QEMU doesn't model this; implement as reads-as-written * A_CFG2 has QSPI select (like AN524) - implemented (no behaviour, as with AN524) * A_CFG3 is MCC_MSB_ADDR "additional MCC addressing bits" - QEMU doesn't care about these, so use the existing RAZ behaviour for convenience * A_CFG4 is board rev (like all other images) - no change needed * A_CFG5 is ACLK frq in hz (like AN524) - implemented as reads-as-written, as for other boards * A_CFG6 is core 0 vector table base address - implemented as reads-as-written for the moment * A_CFG7 is core 1 vector table base address - implemented as reads-as-written for the moment Make the changes necessary for this; leave TODO comments where appropriate to indicate where we might want to come back and implement things like CPU reset. The other aspects of the device specific to this FPGA image (like the values of the board ID and similar registers) will be set via the device's qdev properties.

Unlike the existing FPGA images we already model, this board uses a Cortex-R family CPU, and it does not use any equivalent to the M-profile "Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c. It's therefore more convenient for us to model it as a completely separate C file. This commit adds the basic skeleton of the board model, and the code to create all the RAM and ROM. We assume that we're probably going to want to add more images in future, so use the same base class/subclass setup that mps2-tz.c uses, even though at the moment there's only a single subclass. Following commits will add the CPUs and the peripherals.
