8 dayshw/intc/gicv3_its: Do not check its_class_name()Philippe Mathieu-Daudé1-1/+1
Since commit cc5e719e2c8 ("kvm: require KVM_CAP_SIGNAL_MSI"), the single implementation of its_class_name() no longer returns NULL (it now always returns a valid char pointer). Hence, update the prototype docstring and remove the tautological checks that use the its_class_name() returned value.

register address The INTC controller supports GICINT128 to GICINT136, mapping 1:1 to input and output IRQs 0 to 8. Previously, the formula "address & 0x0f00" was used to derive the IRQ index numbers. However, the INTC controller also supports GICINT192_201, mapping 1 input IRQ pin to 10 output IRQ pins. The pin numbers for input and output are different. It is difficult to use a formula to determine the index number of INTC model supported input and output IRQs. To simplify and improve readability, introduces the AspeedINTCIRQ structure to save the input/output IRQ index and its enable/status register address. Introduce the "aspeed_2700_intc_irqs" table to store IRQ information for INTC.

Currently, the size of the "regs" array is 0x2000, which is too large. So far, it only uses "GICINT128 to `GICINT134", and the offsets from 0 to 0x1000 are unused. To save code size and avoid mapping large unused gaps, update to only map the useful set of registers: INTC register [0x1000 – 0x1804] Update "reg_size" to 0x808. Introduce a new class attribute "reg_offset" to set the start offset of a "INTC" sub-region. Set the "reg_offset" to 0x1000 for INTC registers.

Currently, the size of the regs array is 0x2000, which is too large. So far, it only use GICINT128 - GICINT134, and the offsets from 0 to 0x1000 are unused. To save code size, introduce a new class attribute "reg_size" to set the different register sizes for the INTC models in AST2700 and add a regs sub-region in the memory container.

Currently, the size of the "regs" array is 0x2000, which is too large. To save code size and avoid mapping large unused gaps, will update it to only map the useful set of registers. This update will support multiple sub-regions with different sizes. To address the redundant size issue, replace the static "regs" array with a dynamically allocated "regs" memory. Introduce a new "aspeed_intc_unrealize" function to free the allocated "regs" memory.

2024-12-20hw/intc/riscv_aplic: add kvm_msicfgaddr for split mode aplic-imsicDaniel Henrique Barboza1-0/+6
The last step to enable KVM AIA aplic-imsic with irqchip in split mode is to deal with how MSIs are going to be sent. 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=aplic-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().

2024-12-20hw/riscv/virt.c, riscv_aplic.c: add 'emulated_aplic' helpersDaniel Henrique Barboza1-0/+1
The current logic to determine if we don't need an emulated APLIC controller, i.e. KVM will provide for us, is to determine if we're running KVM, with in-kernel irqchip support, and running aia=aplic-imsic. 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=aplic'. 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().
