Subject: [PATCH v2 0/6] RISC-V: KVM: Allow zicbop/bfloat16 exts for guests
Date: Fri,  8 Aug 2025 18:18:10 +0800	[thread overview]
Message-ID: <cover.1754646071.git.zhouquan@iscas.ac.cn> (raw)

From: Quan Zhou <zhouquan@iscas.ac.cn>

Advertise zicbop/bfloat16 extensions to KVM guest when underlying
host supports it, and add them to get-reg-list test.

---
Change since v1:
- update zicbom/zicboz/zicbop block size registers to depend on the host isa.
- update the reg list filtering in copy_config_reg_indices() to use the host isa.
- add reg list filtering for zicbop.
v1: https://lore.kernel.org/all/cover.1750164414.git.zhouquan@iscas.ac.cn/
