Subject: [PATCH v8 02/24] RISC-V: Add FIRMWARE_READ_HI definition
Date: Sat, 20 Apr 2024 08:17:18 -0700	[thread overview]
Message-ID: <20240420151741.962500-3-atishp@rivosinc.com> (raw)
In-Reply-To: <20240420151741.962500-1-atishp@rivosinc.com>

SBI v2.0 added another function to SBI PMU extension to read
the upper bits of a counter with width larger than XLEN.

Add the definition for that function.
