* hw/char: sifive_uart: Print uart characters asyncAlistair Francis2024-10-301-2/+14
| | | | | | | | | | | | | | | | | | | | | 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>

* sifive: Move QOM typedefs and add missing includesEduardo Habkost2020-09-181-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Daniel P.

* hw/riscv: Move sifive_uart model to hw/charBin Meng2020-09-091-0/+77
This is an effort to clean up the hw/riscv directory. Ideally it should only contain the RISC-V SoC / machine codes plus generic codes. Let's move sifive_uart model to hw/char directory.
