Neither is the SVE vector length fixed.
That's one of the reasons I pointed you at the

When I port RISU, I find this bug. I can't get the correct registers from the
struct ucontext_t parameter in the signal handler.
The RISC-V Linux ABI will need to be extended to handle RVV state.

That's what I thought. Thanks :)
Applied to the RISC-V tree for 5.1.

There is room in your sigcontext structure:

When I port RISU, I find this bug. I can't get the correct registers
from the
struct ucontext_t parameter in the signal handler.
If you want to reproduce it, just register a signal handler for SIGILL,
and output an illegal instruction, such as
#include
#include
#include
#include
As struct target_ucontext will be transfered to signal handler, it
must keep pace with struct ucontext_t defined in Linux kernel.
