Subject: [PATCH 0/2] riscv: fix envcfg.STCE
Date: Mon, 23 Jun 2025 18:53:27 +0200	[thread overview]
Message-ID: <20250623165329.2759651-1-rkrcmar@ventanamicro.com> (raw)

Hello,

I reviewed a very unintuitive implementation of Sstc in Sail, and QEMU
seems to have a minor bug there, which is addressed [1/2].
[2/2] is just a sanitization.

I only compiled the code, and have no idea how to easily test it, so
feel free to drop the patches, and treat this as a bug report.

Thanks.

  target/riscv: disable *stimecmp interrupts without *envcfg.STCE
  target/riscv: disarm timer when writing past value
