Subject: [kvmtool PATCH 06/10] riscv: Make system suspend time configurable
Date: Wed, 26 Mar 2025 12:26:40 +0530	[thread overview]
Message-ID: <20250326065644.73765-7-apatel@ventanamicro.com> (raw)
In-Reply-To: <20250326065644.73765-1-apatel@ventanamicro.com>

From: Andrew Jones <ajones@ventanamicro.com>

If the default of 5 seconds for a system suspend test is too long or
too short, then feel free to change it.
