Subject: [PATCH v3] Work with hartid equal to or greater than SBI_HARTMASK_MAX_BITS
Date: Mon, 20 Jan 2025 17:12:34 -0800 [thread overview]
Message-ID: <20250121011234.717311-1-Raj.Vishwanathan@gmail.com> (raw)
In-Reply-To: <20250115234607.410148-1-Raj.Vishwanathan@gmail.com>
Some platforms use hartid that is equal to greater than SBI_HARTMASK_MAX_BITS,
so we should remove the original check. Instead we check the hart index
against SBI_HARTMASK_MAX_BITS.
Update: Make hart_count > SBI_HARTMASK_MAX_BITS a catastrophic failure. The reviewer suggested continue, immediate failure quickly will localize the issue.
