target/riscv: Add sscofpmf extension support The Sscofpmf ('Ss' for Privileged arch and Supervisor-level extensions, and 'cofpmf' for Count OverFlow and Privilege Mode Filtering) extension allows the perf to handle overflow interrupts and filtering support. This patch provides a framework for programmable counters to leverage the extension. As the extension doesn't have any provision for the overflow bit for fixed counters, the fixed events can also be monitoring using programmable counters. The underlying counters for cycle and instruction counters are always running. Thus, a separate timer device is programmed to handle the overflow.

target/riscv: Add sscofpmf extension support The Sscofpmf ('Ss' for Privileged arch and Supervisor-level extensions, and 'cofpmf' for Count OverFlow and Privilege Mode Filtering) extension allows the perf to handle overflow interrupts and filtering support. This patch provides a framework for programmable counters to leverage the extension. As the extension doesn't have any provision for the overflow bit for fixed counters, the fixed events can also be monitoring using programmable counters. The underlying counters for cycle and instruction counters are always running. Thus, a separate timer device is programmed to handle the overflow.

target/riscv: Move Guest irqs out of the core local irqs range. Qemu maps IRQs 0:15 for core interrupts and 16 onward for guest interrupts which are later translated to hgiep in `riscv_cpu_set_irq()` function. With virtual IRQ support added, software now can fully use the whole local interrupt range without any actual hardware attached. This change moves the guest interrupt range after the core local interrupt range to avoid clash. Fixes: 1697837ed9 ("target/riscv: Add M-mode virtual interrupt and IRQ filtering support.")

target/riscv: Add M-mode virtual interrupt and IRQ filtering support. This change adds support for inserting virtual interrupts from M-mode into S-mode using mvien and mvip csrs. IRQ filtering is a use case of this change, i-e M-mode can stop delegating an interrupt to S-mode and instead enable it in MIE and receive those interrupts in M-mode and then selectively inject the interrupt using mvien and mvip. Also, the spec doesn't mandate the interrupt to be actually supported in hardware. Which allows M-mode to assert virtual interrupts to S-mode that have no connection to any real interrupt events. This is defined as part of the AIA specification [0], "5.3 Interrupt filtering and virtual interrupts for supervisor level".

target/riscv: Update default priority table for local interrupts The latest AIA draft v0.3.0 defines a relatively simpler scheme for default priority assignments where: 1) local interrupts 24 to 31 and 48 to 63 are reserved for custom use and have implementation specific default priority. 2) remaining local interrupts 0 to 23 and 32 to 47 have a recommended (not mandatory) priority assignments. We update the default priority table and hviprio mapping as-per above.

target/riscv: Add sscofpmf extension support The Sscofpmf ('Ss' for Privileged arch and Supervisor-level extensions, and 'cofpmf' for Count OverFlow and Privilege Mode Filtering) extension allows the perf to handle overflow interrupts and filtering support. This patch provides a framework for programmable counters to leverage the extension. As the extension doesn't have any provision for the overflow bit for fixed counters, the fixed events can also be monitoring using programmable counters. The underlying counters for cycle and instruction counters are always running. Thus, a separate timer device is programmed to handle the overflow.
