- Remove the futile attempts to cleanup resources when the probing of the
main interrupt chip fails for SiFIVE/PLIC devices. If that probe fails
the system will stall immediately afterwards in the boot process
without reaching a state where the error could be diagnosed. The lack
of resource cleanup led to a frenzy of AI detected/assisted "fixes"
which just make the code pretend to be correct for no value.
Remove the existing half baked cleanup and immediately panic the
machine when the probe fails. That's far more useful than letting it
proceed and stall out a millisecond later with no information about the
root cause.
- A series of fixes for the ARM GIC-V3 driver addressing a potential
double free, a bitmask overrun on 32-bit ARM and a OF node leak.
- Automatically set the IRQ_DOMAIN_FLAG_DESTROY_GC when a interrupt
domain is created that also allocates the generic interrupt chip during
domain creation. That removes the requirement for manually setting the
flag in the domain creation info structure when it contains a valid
entry for allocating the generic interrupt chip. Remove the therefore
redundant setters of IRQ_DOMAIN_FLAG_DESTROY_GC in the existing
drivers.
- Add support for Annapurna Labs FIC version 2 and 3 and implement
affinity control for the demultiplexed interrupts by utilizing the
recently merged interrupt redirection infrastructure.
- Convert the ACPI device ID structures to named initializers
- Consolidate the IPI related constants for RISC-V interrupt controllers
- Add support for Qualcomm Purwa SoC interrupt chip and consolidate the
workaround for the previous version in Hamoa SoCs.
- The usual small fixes and improvements all over the place
