This series adds a QEMU model for the K230 SoC DesignWare 8250-compatible UART controller, wires it into the K230 SoC, and adds qtest coverage.
The implementation supports the registers and features required by the Linux 8250_dw driver, providing an interactive shell over the serial port. Signed-off-by: WX Chen <[email protected]> --- Changes in v3: - Removed all hardwired preprocessor #if conditionals from the logic - Added a helper for the receiver line status interrupt check - Encapsulated CPR and UCV register values in header macros - Replaced g_usleep() with qtest_clock_step() in the qtest - Link to v2: https://lore.kernel.org/qemu-devel/[email protected] --- WX Chen (3): hw/char: add K230 DW 8250-compatible UART hw/riscv: k230: connect DW 8250 UART tests/qtest: add K230 UART test hw/char/Kconfig | 3 + hw/char/k230_uart.c | 816 +++++++++++++++++++++++++++++++++++++++++++ hw/char/meson.build | 1 + hw/riscv/k230.c | 33 +- include/hw/char/k230_uart.h | 198 +++++++++++ include/hw/riscv/k230.h | 6 +- tests/qtest/k230-uart-test.c | 514 +++++++++++++++++++++++++++ tests/qtest/meson.build | 2 +- 8 files changed, 1559 insertions(+), 14 deletions(-) --- base-commit: 30e8a06b64aa58a3990ba39cb5d09531e7d265e0 change-id: 20260808-feat-k230-uart-v3-0ff3651d70ef Best regards, -- WX Chen <[email protected]>
