linux/poky.git/meta/conf/machine/include/riscv, branch master

The poky repository master branch is no longer being updated.

2025-11-07T13:31:53+00:00

You can either: a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs b) use the new bitbake-setup You can find information about either approach in our documentation: https://docs.yoctoproject.org/ Note that "poky" the distro setting is still available in meta-yocto as before and we continue to use and maintain that. Long live Poky! Some further information on the background of this change can be found in: https://lists.openembedded.org/g/openembedded-architecture/message/2179 Signed-off-by: Richard Purdie

qemuriscv: Use RVA23S64 profile for cpu

2025-09-25T10:09:05+00:00

Enables RVV extensions uniformly across gcc and clang as it is mandatory in RVA23 spec. https://github.com/riscv/riscv-profiles/blob/main/src/rva23-profile.adoc (From OE-Core rev: 119d63b2e277ca98af593a3fd8add31ca34361af) Signed-off-by: Khem Raj Signed-off-by: Mathieu Dubois-Briand Signed-off-by: Richard Purdie

bitbake/conf: Default to zstd compressed image output

2025-08-06T21:32:42+00:00

Switch our default qemu images to use .zst compressed images by default since this is the output format we release during the release process and is the one that users would prefer to download. This makes the release process use the actual generated output from the system and avoids post processing. (From OE-Core rev: aa5f60d1fcb716a2b2174dffcaf35442bff1f1fb) Signed-off-by: Richard Purdie

riscv tunes: ISA Implementation of RISC-V tune features

2025-06-20T08:52:28+00:00

This implements the following base ISAs: * rv32i, rv64i * rv32e, rv64i The following ABIs: * ilp32, ilp32e, ilp32f, ilp32d * lp64, lp64e, lp64f, lp64d The following ISA extension are also implemented: * M - Integer Multiplication and Division Extension * A - Atomic Memory Extension * F - Single-Precision Floating-Point Extension * D - Double-Precision Floating-Point Extension * C - Compressed Extension * B - Bit Manipulation Extension (implies Zba, Zbb, Zbs) * V - Vector Operations Extension * Zicsr - Control and Status Register Access Extension * Zifencei - Instruction-Fetch Fence Extension * Zba - Address bit manipulation extension * Zbb - Basic bit manipulation extension * Zbc - Carry-less multiplication extension * Zbs - Single-bit manipulation extension * Zicbom - Cache-block management extension The existing processors tunes are preserved: * riscv64 (rv64gc) * riscv32 (rv32gc) * riscv64nf (rv64imac_zicsr_zifencei) * riscv32nf (rv32imac_zicsr_zifencei) * riscv64nc (rv64imafd_zicsr_zifencei) Previously defined feature 'big-endian' has been removed as it was not used.

qemuriscv: Enable Sv39 memory address scheme by default

2025-02-05T12:49:56+00:00

Currently, GCC Asan supports only Sv39 on RISC-V 64 due to custom allocator configurations optimized for large allocations. These configurations are incompatible with larger address spaces like Sv48/Sv57. This fix enables RISC-V 64 configuration for RVA22S64 profile(which has sv39 mode and other extensions) by default when running `runqemu nographic`, eliminating the need for manual configuration via command line flags (`qemuparams="-cpu rv64, sv39=true"`).

tclibc-picolibc: Adds a new TCLIBC variant to build with picolibc as C library

2024-07-26T11:28:42+00:00

Enables usage of TCLIBC=picolibc extending OE functionality to build and use picolibc based toolchains to build baremetal applications. Picolibc is a set of standard C libraries, both libc and libm, designed for smaller embedded systems with limited ROM and RAM. Picolibc includes code from Newlib and AVR Libc, but adresses some of newlibs concerns, it retains newlibs directory structure, math, string and locale implementations, but removed the GPL bits used to build the library, swiches old C style code for C18 and replaces autotools with meson. This patch adds a picolibc recipe for the C library, a picolibc-helloworld recipe that contains an example application and a testcase that builds it. Picolibc can be built for ARM and RISCV architectures, its been tested both for 32 and 64 bits, the provided example recipe produces the following output: hello, world Runqemu does not automatically show any output since it hides QEMU stderr which is where the QEMU monitors output is directed to when using semihosting, but, manually running the same QEMU command does work properly.

qemuriscv: Add to common MACHINE_FEATURES instead of overriding them

2023-11-05T11:28:30+00:00

machine features like vfat are needed for ptests to pass ( e..g. parted) This brings it closer to what x86 qemu config looks like as well.

meta/conf/machine: remove SERIAL_CONSOLES_CHECK

There's no need for this variable anymore, as all consoles listed in SERIAL_CONSOLES are checked for their existence before a getty is started. (From OE-Core rev: 8a1060952f8b6956acf747f3853401ac8a981fc3) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

runqemu/qemurunner: Use nodelay with tcp serial connections
