Mark Zhuang 037e89fdd1 RISCV: enable some cpu extensions for spacemit k1
spacemit vendor linux kernel is spacemit,k1-x:
k1-x is from spacemit https://gitee.com/bianbu-linux/linux-6.6/blob/k1-bl-v2.1.y/arch/riscv/boot/dts/spacemit/k1-x.dtsi#L17
while upstream linux kernel is spacemit,k1:

Brad Smith e1916bf1fe CMake: Add checks for getauxval and elf_aux_info
Add support for CPU feature detection on OpenBSD and FreeBSD riscv64.

Brad Smith 59ba9ab973 Fix building on OpenBSD/riscv64.
Unbreak on riscv64, we don't have sys/auxv.h or getauxval().

OpenBSD/riscv64 assumes RV64GC, aka RV64IMAFDC.

Our kernel provides no support for the V extension.

Unknown W. Brackets 52db66e7ad riscv: Add vector bitmanip encoding. 2023-12-29 09:42:23 -08:00
Unknown W. Brackets 83dc1c9705 riscv: Add detect flags, not detected yet. 2023-12-29 09:42:23 -08:00
Henrik Rydgård e3177ac870 Make some global string pointers const, not just the strings.
Minor cleanup.

Unknown W. Brackets 030a27f15d riscv: Stop considering bitmanip "B".
Apparently it's not being called B anymore and B is still reserved.

Unknown W. Brackets 63f370916b riscv: Enable Zba/Zbb by soc compatible.
Instead of u74, because apparently some older u74 don't support it.

Unknown W. Brackets 04ce3a0572 riscv: Allow subset of B extension to be used. 2023-02-16 16:09:22 -08:00

Unknown W. Brackets 09eb509df4 Common: Expose CPU extension list directly.
A bit silly to rely on the specific string formatting of a summary.

Unknown W. Brackets 3bc2450b5e riscv: Add bitmanip instructions to emitter (#16832)
* riscv: Cleanup emitter, add bitmanip detect.

Better to encode using Funct7::ZERO, and obviously for SRA.

* riscv: Add bitmanip instructions to emitter.
