The current approach of using qemu_chr_fe_write() and ignoring the return values results in dropped characters [1]. Let's update the SiFive UART to use a async sifive_uart_xmit() function to transmit the characters and apply back pressure to the guest with the SIFIVE_UART_TXFIFO_FULL status. This should avoid dropped characters and more realisticly model the hardware. 1: https://gitlab.com/qemu-project/qemu/-/issues/2114 Signed-off-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Daniel Henrique Barboza <dbarboza@ventanamicro.com> Tested-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-ID: <20240910045419.1252277-3-alistair.francis@wdc.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com> |
