platform: qemu-virt: Implement system shutdown

2019-02-18T03:51:58Z

In order for QEMU to be compatible with Spike, it implements a simple protocol used for reporting back the simulation's status, through the memory-mapped "test finisher" device. We use that protocol to make QEMU exit on system shutdown. Signed-off-by: Nick Kossifidis

Makefile: Add 'make run' command for platform specific run

2019-02-15T10:24:44Z

Makes for easy and quick build-run one-stop command. For now only added for qemu targets. It can be added for any platform having simulator/emulator (such as QEMU). Signed-off-by: Olof Johansson Signed-off-by: Anup Patel

Makefile: Set ABI, ISA and Code Model in top-level make

2019-02-12T10:25:15Z

This patch introduces following optional PLATFORM options: PLATFORM_RISCV_XLEN -> RISC-V register width PLATFORM_RISCV_ABI -> RISC-V GCC ABI PLATFORM_RISCV_ISA -> RISC-V GCC ISA string PLATFORM_RISCV_CODE_MODEL -> RISC-V GCC Code Model If the above options are not provided by platform config.mk or by command-line parameters then: 1. PLATFORM_RISCV_XLEN will be determined using toolchain capability 2. PLATFORM_RISCV_ABI, PLATFORM_RISCV_ISA, and PLATFORM_RISCV_CODE_MODEL is set to value best suited for generic libsbi.a As a result of these optional PLATFORM options, the platform-cflags-y and platform-asflags-y is further simplified for platform config.mk.

platform: qemu: Set FW_JUMP_ADDR and FW_PAYLOAD_OFFSET as-per XLEN

2019-02-12T10:25:15Z

The current 4MB aligned FW_JUMP_ADDR and FW_PAYLOAD_OFFSET breaks U-Boot on QEMU virt and sifive_u machines. Instead of using 4MB aligned for both 32bit and 64bit systems, we use different values based compiler XLEN. Another advantage of this approach will be that our fw_payload.bin will smaller for 64bit systems. Signed-off-by: Anup Patel

platform: qemu/virt: Move kernel start address to 4MB alligned

2019-02-08T03:48:46Z

In order to support 32-bit guests move the start address to a 4MB allignment. As 64-bit kernels have a requirement on being 2MB alligned let's just make this the default for both 32 and 64 bit kernels. Signed-off-by: Alistair Francis

platform/qemu/virt: Dynamically calculate xlen

2019-02-08T03:48:46Z

The QEMU virt machine can be either 32 or 66 bit. Don't hard code the CPU bit length and instead let the compiler determine it. Signed-off-by: Alistair Francis

all: Update copyright header in all files

2019-01-24T08:37:47Z

This patch updates copyright header in all files as follows: 1. Makes "SPDX-License-Identifier: BSD-2-Clause" as first line 2. Change copyright year to 2019 for Western Digital Signed-off-by: Anup Patel

include: Rename ipi_inject() to ipi_send() for sbi_platform

2019-01-23T03:09:26Z

For better naming, we rename ipi_inject() to ipi_send() in struct sbi_platform. We also replace term "inject" with "send" in all related places. Signed-off-by: Anup Patel

lib: Remove target_hart and hartid parameter from TIMER callbacks

2019-01-23T03:09:26Z

The target_hart and hartid paramter of TIMER callbacks is not required because it always current hartid which can be obtained using sbi_current_hartid() API. Signed-off-by: Anup Patel

lib: Remove hartid parameter from IRQCHIP callbacks

2019-01-23T03:09:26Z

The hartid parameter in IRQCHIP callbacks of sbi_platform is not required because current hartid can be determined using sbi_current_hartid() API. Signed-off-by: Anup Patel
