lib: utils/irqchip/imsic: embed sbi_irqchip_device in imsic data

2026-07-22T07:38:15Z

Embed sbi_irqchip_device in struct imsic_data to enable instance-based irqchip registration, replacing the previous global imsic_device singleton. Include sbi_irqchip.h from imsic.h to make the embedded struct visible to consumers.

lib: utils/irqchip/aplic: add MSI mode support with IMSIC parent linking

2026-07-22T07:38:13Z

Add parent_unique_id fields to struct aplic_data for IMSIC parent linking in MSI mode. Store parent IMSIC unique_id during FDT parsing of the APLIC node. Add aplic_is_msi_mode() complementing aplic_is_direct_mode() to consolidate delivery mode detection. Add APLIC_TARGET_EIID() macro for packing the EIID field into the TARGET register. Add parent_unique_id and parent_irq_map fields to struct aplic_data. parent_unique_id identifies the upstream IMSIC irqchip device resolved via sbi_irqchip_find_device() during hwirq_setup. parent_irq_map is a per-source array allocated at cold init time to track the EIID assigned by the IMSIC for each APLIC source. Restore aplic_writel_msicfg() and re-introduce MSI address register programming in aplic_init(), gated on aplic_is_msi_mode(). Set the DOMAINCFG_DM bit to switch the hardware to MSI delivery mode when no IDC structures are present. Add aplic_program_msi_target() to pack hart_index, guest_index, and EIID into the APLIC_TARGET register. Add aplic_write_msi() as the sbi_irqchip write_msi callback that extracts EIID and hart_index from the MSI message and calls aplic_program_msi_target(). Add aplic_msi_callback() as the MSI receive callback that dispatches to sbi_irqchip_process_hwirq() on the APLIC chip. Extend aplic_hwirq_setup() with an MSI path that resolves the parent IMSIC chip by parent_unique_id, registers an MSI route via sbi_irqchip_register_msi(), and stores the allocated EIID in parent_irq_map for the source being configured. Extend aplic_hwirq_set_affinity() with an MSI path that delegates affinity reprogramming to the parent IMSIC chip via sbi_irqchip_set_affinity() using the stored parent_irq_map entry. Guard warm_init, process_hwirqs, and hwirq_eoi with early returns in MSI mode as interrupt delivery and acknowledgement are handled by the IMSIC in that configuration.

platform: generic: Optimize extensions_init() to parse ISA extensions once

2026-06-12T10:38:29Z

Instead of parsing ISA extensions separately for each hart in the generic_extensions_init() function, it is better to parse ISA extensions for all available harts in the cold boot path. Also, this allows us to remove fdt_isa_bitmap from scratch space and directly initialize "extensions" in struct sbi_hart_features for each hart.
