RISC-V: Add a basic defconfig 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>

RISC-V: defconfig: Enable NO_HZ_IDLE and HIGH_RES_TIMERS This patch enables NO_HZ_IDLE (idle dynamic ticks) and HIGH_RES_TIMERS (hrtimers) in RV32 and RV64 defconfigs. Both of the above options are enabled by default for architectures such as x86, ARM, and ARM64. The idle dynamic ticks helps use save power by stopping timer ticks when the system is idle whereas hrtimers is a much improved timer subsystem compared to the old "timer wheel" based system. This patch is tested on SiFive Unleashed board and QEMU Virt machine.

RISC-V: Add a basic defconfig 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>
