This patch adds support for the Zawrs ISA extension. Given the current (incomplete) implementation of reservation sets there seems to be no way to provide a full emulation of the WRS instruction (wake on reservation set invalidation or timeout or interrupt). Therefore, we just exit the TB and return to the main loop. The specification can be found here: https://github.com/riscv/riscv-zawrs/blob/main/zawrs.adoc Note, that the Zawrs extension is frozen, but not ratified yet. Changes since v3: * Remove "RFC" since the extension is frozen * Rebase on master and fix integration issues * Fix entry ordering in extension list Changes since v2: * Rebase on master and resolve conflicts * Adjustments according to a specification change * Inline REQUIRE_ZAWRS() since it has only one user Changes since v1: * Adding zawrs to the ISA string that is passed to the kernel Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-Id: <20221005144948.3421504-1-christoph.muellner@vrull.eu> Signed-off-by: Alistair Francis <alistair.francis@wdc.com> |
