2018-08-13RISC-V: remove INTERRUPT_CAUSE_* defines from asm/irq.hChristoph Hellwig
These are only of use to the local irq controller driver, so add them in that driver implementation instead, which will be submitted soon. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
2018-08-13RISC-V: simplify software interrupt / IPI codeChristoph Hellwig
Rename handle_ipi to riscv_software_interrupt, drop the unused return value and move the prototype to irq.h together with riscv_timer_interupt. This allows simplifying the upcoming interrupt handling support. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
2017-09-26RISC-V: Device, timer, IRQs, and the SBIPalmer Dabbelt
This patch contains code that interfaces with devices that are mandated by the RISC-V supervisor specification and that don't have explicit drivers anywhere else in the tree. This includes the staticly defined interrupts, the CSR-mapped timer, and virtualized SBI devices. Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>
