From RISCV IOMMU spec section 2.3 step 17: Use the process specified in Section "Two-Stage Address Translation" of the RISC-V Privileged specification to determine the GPA accessed by the transaction. From RISCV IOMMU spec section 2.3 step 19: Use the second-stage address translation process specified in Section "Two-Stage Address Translation" of the RISC-V Privileged specification to translate the GPA A to determine the SPA accessed by the transaction. This commit adds the iova check with the following rules: - For Sv32, Sv32x4, Sv39x4, Sv48x4 and Sv57x4, the iova must be zero extended. - For Sv39, Sv48 and Sv57, the iova must be signed extended with most significant bit.

The same design decisions taken in the riscv-iommu-pci device were kept, namely the existence of 4 vectors are available for each interrupt cause. The WSIs are emitted using the input of the s->notify() callback as a index to an IRQ list. The IRQ list starts at 'base_irq' and goes until base_irq + 3. This means that boards must have 4 contiguous IRQ lines available, starting from 'base_irq'.

The option is default 'off'. The device will use IRQs 36 to 39. We will not support both riscv-iommu-sys and riscv-iommu-pci devices in the same board in this first implementation. If a riscv-iommu-pci device is added in the command line we will disable the riscv-iommu-sys device.

We took inspiration of what is being done in the riscv-iommu-pci device, mainly msix_init() and msix_notify(), while keeping in mind that riscv-iommu-sys isn't a true PCI device and we don't need to copy/paste all the contents of these MSIx functions. Two extra MSI MemoryRegions were added: 'msix-table' and 'msix-pba'. They are used to manage r/w of the MSI table and Pending Bit Array (PBA) respectively. Both are subregions of the main IOMMU memory region, iommu->regs_mr, initialized during riscv_iommu_realize(), and each one has their own handlers for MSIx reads and writes. This is the expected memory map when using this device in the 'virt' machine: 0000000003010000-0000000003010fff (prio 0, i/o): riscv-iommu-regs 0000000003010300-000000000301034f (prio 0, i/o): msix-table 0000000003010400-0000000003010407 (prio 0, i/o): msix-pba We're now able to set IGS to RISCV_IOMMU_CAP_IGS_BOTH, and userspace is free to decide which interrupt model to use. Enabling MSIx support for this device in the 'virt' machine requires adding 'msi-parent' in the iommu-sys DT.

Rename it to be a bit clear what the helper is doing since we'll add more AIA helpers in the next patches. Make the helper public because the 'virt' machine will use it as well.

In the use case we have so far, i.e. in-kernel irqchip without split mode, both the s-mode APLIC and IMSIC controllers are provided by the irqchip. In irqchip_split() mode we'll emulate the s-mode APLIC controller, which will send MSIs to the in-kernel IMSIC controller. To do that we need to change kvm_riscv_aia_create() to not create the in-kernel s-mode APLIC controller. In the kernel source arch/riscv/kvm/aia_aplic.c, function kvm_riscv_aia_aplic_init(), we verify that the APLIC controller won't be instantiated by KVM if we do not set 'nr_sources', which is set via KVM_DEV_RISCV_AIA_CONFIG_SRCS. For QEMU this means that we should not set 'aia_irq_num' during kvm_riscv_aia_create() in irqchip_split() mode. In this same condition, skip KVM_DEV_RISCV_AIA_ADDR_APLIC as well since it is used to set the base address for the in-kernel APLIC controller.

This is modelled by riscv_is_kvm_aia_aplic_imsic() and virt_use_kvm_aia_aplic_imsic(). This won't suffice to support irqchip_split() mode: it will match exactly the same conditions as the one above, but setting the irqchip to 'split' mode will now require us to emulate an APLIC s-mode controller, like we're doing with 'aia=3Daplic'. Create a new riscv_use_emulated_aplic() helper that will encapsulate this logic. Replace the uses of "riscv_is_kvm_aia_aplic_imsic()" with this helper every time we're taking a decision on emulate an APLIC controller or not. Do the same in virt.c with virt_use_emulated_aplic().

In our current design we don't allow an APLIC controller to send MSIs unless it's on m-mode. And we also do not allow Supervisor MSI address configuration via the 'smsiaddrcfg' and 'smsiaddrcfgh' registers unless it's also a m-mode APLIC controller. Add a new RISCVACPLICState attribute called 'kvm_msicfgaddr'. This attribute represents the base configuration address for MSIs, in our case the base addr of the IMSIC controller. This attribute is being set only when running irqchip_split() mode with aia=3Daplic-imsic. During riscv_aplic_msi_send() we'll check if the attribute was set to skip the check for a m-mode APLIC controller and to change the resulting MSI addr by adding kvm_msicfgaddr right before address_space_stl_le().

This is basic configuration which matches HW generated out of AMD Vivado (design tools). But initial configuration is going beyond what it is configured by default because validation should be done on other configurations too. That's why wire also additional uart16500, axi ethernet(with axi dma). GPIOs, i2c and qspi is also listed for completeness. IRQ map is: (addr) 0 - timer (0x41c00000) 1 - uartlite (0x40600000) 2 - i2c (0x40800000) 3 - qspi (0x44a00000) 4 - uart16550 (0x44a10000) 5 - emaclite (0x40e00000) 6 - timer2 (0x41c10000) 7 - axi emac (0x40c00000) 8 - axi dma (0x41e00000) 9 - axi dma 10 - gpio (0x40000000) 11 - gpio2 (0x40010000) 12 - gpio3 (0x40020000) Signed-off-by: Sai Pavan Boddu Signed-off-by: Michal Simek Reviewed-by: Alistair Francis Message-ID: <20241125134739.18189-1-sai.pavan.boddu@amd.com> Signed-off-by: Alistair Francis --- MAINTAINERS | 6 + docs/system/riscv/microblaze-v-generic.rst | 42 +++++ docs/system/target-riscv.rst | 1 + hw/riscv/microblaze-v-generic.c | 184 +++++++++++++++++++++ hw/riscv/Kconfig | 8 + hw/riscv/meson.build | 1 + 6 files changed, 242 insertions(+) create mode 100644 docs/system/riscv/microblaze-v-generic.rst create mode 100644 hw/riscv/microblaze-v-generic.c diff --git a/MAINTAINERS b/MAINTAINERS index 430a0f4f8c..fb6a66f1f8 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -1626,6 +1626,12 @@ F: docs/system/riscv/sifive_u.rst F: hw/*/*sifive*.c F: include/hw/*/*sifive*.h =20 +AMD Microblaze-V Generic Board +M: Sai Pavan Boddu +S: Maintained +F: hw/riscv/microblaze-v-generic.c +F: docs/system/riscv/microblaze-v-generic.rst + RX Machines ----------- rx-gdbsim diff --git a/docs/system/riscv/microblaze-v-generic.rst b/docs/system/riscv= /microblaze-v-generic.rst new file mode 100644 index 0000000000..5606f88d57 --- /dev/null +++ b/docs/system/riscv/microblaze-v-generic.rst @@ -0,0 +1,42 @@ +Microblaze-V generic board (``amd-microblaze-v-generic``) +=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D +The AMD MicroBlaze=E2=84=A2 V processor is a soft-core RISC-V processor IP= for AMD +adaptive SoCs and FPGAs.

It makes little sense to show user warnings for named extensions that users can't control, and the solution taken was to disable zic64b manually in riscv_cpu_update_named_features(). This solution won't scale well when adding more named features, and can eventually end up repeating riscv_cpu_disable_priv_spec_isa_exts(). Change riscv_cpu_disable_priv_spec_isa_exts() to not show warnings when disabling a named feature. This will accomplish the same thing we're doing today while avoiding having two points where we're disabling exts via priv_ver mismatch.
