2018-11-01RISC-V: refresh defconfigAnup Patel
This patch updates defconfig using savedefconfig on Linux-4.19. It is intended to have no functional change. Signed-off-by: Anup Patel <anup@brainfault.org> Reviewed-by: Palmer Dabbelt <palmer@sifive.com> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
2018-08-13irqchip: add a SiFive PLIC driverChristoph Hellwig
Add a driver for the SiFive implementation of the RISC-V Platform Level Interrupt Controller (PLIC). The PLIC connects global interrupt sources to the local interrupt controller on each hart. This driver is based on the driver in the RISC-V tree from Palmer Dabbelt, but has been almost entirely rewritten since, and includes many fixes from Atish Patra.

2018-06-11RISC-V: Add CONFIG_HVC_RISCV_SBI=y to defconfigPalmer Dabbelt
The SBI exists on all RISC-V systems, so there's no reason not to compile this driver in. Signed-off-by: Palmer Dabbelt <palmer@sifive.com>

2018-01-07RISC-V: Add a basic defconfigKarsten Merker
This patch provides a basic defconfig for the RISC-V architecture that enables enough kernel features to run a basic Linux distribution on qemu's "virt" board for native software development. Features include: - serial console - virtio block and network device support - VFAT and ext2/3/4 filesystem support - NFS client and NFS rootfs support - an assortment of other kernel features required for running systemd It also enables a number of drivers for physical hardware that target the "SiFive U500" SoC and the corresponding development platform. These include: - PCIe host controller support for the FPGA-based U500 development platform (PCIE_XILINX) - USB host controller support (OHCI/EHCI/XHCI) - USB HID (keyboard/mouse) support - USB mass storage support (bulk and UAS) - SATA support (AHCI) - ethernet drivers (MACB for a SoC-internal MAC block, microsemi ethernet phy, E1000E and R8169 for PCIe-connected external devices) - DRM and framebuffer console support for PCIe-connected Radeon graphics chips Signed-off-by: Karsten Merker <merker@debian.org> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
2017-09-26RISC-V: Build InfrastructurePalmer Dabbelt
This patch contains all the build infrastructure that actually enables the RISC-V port. This includes Makefiles, linker scripts, and Kconfig files. It also contains the only top-level change, which adds RISC-V to the list of architectures that need a sed run to produce the ARCH variable when building locally.
