| 2023-08-08 | RISC-V: KVM: Improve vector save/restore functions | Andrew Jones | 1 | -4/+2 | |
| Make two nonfunctional changes to the vector get/set vector reg functions and their supporting function for simplification and readability. The first is to not pass KVM_REG_RISCV_VECTOR, but rather integrate it directly into the masking. The second is to rename reg_val to reg_addr where and address is used instead of a value. Also opportunistically touch up some of the code formatting for a third nonfunctional change.

| 2023-06-08 | riscv: KVM: Add vector lazy save/restore support | Vincent Chen | 1 | -0/+82 | |
| This patch adds vector context save/restore for guest VCPUs. To reduce the impact on KVM performance, the implementation imitates the FP context switch mechanism to lazily store and restore the vector context only when the kernel enters/exits the in-kernel run loop and not during the KVM world switch.
