The goal is to automate tests for GNAT (GNU Ada) compiler +that I ported recently to the sh4-linux target. + +Registers +--------- + +16 general purpose registers are available at any time. The first 8 +registers are banked and the non-directly visible ones can be accessed +by privileged instructions. In qemu, we define 24 general purpose +registers and the code generation use either [0-7]+[8-15] or +[16-23]+[8-15] depending on the MD and RB flags in the sr +configuration register. + +Instructions +------------ + +Most sh4 instructions have been implemented. The missing ones at this +time are: + - FPU related instructions + - LDTLB to load a new MMU entry + - SLEEP to put the processor in sleep mode + +Most instructions could be optimized a lot. This will be worked on +after the current model is fully functional unless debugging +convenience requires that it is done early. + +Many instructions did not have a chance to be tested yet. The plan is +to implement unit and regression testing of those in the future. + +MMU +--- + +The MMU is implemented in the sh4 core. MMU management has not been +tested at all yet. In the sh7750, it can be manipulated through memory +mapped registers and this part has not yet been implemented. + +Exceptions +---------- + +Exceptions are implemented as described in the sh4 reference manual +but have not been tested yet. They do not use qemu EXCP_ features +yet. + +IRQ +--- + +IRQ are not implemented yet. + +Peripheral features +------------------- + + + Serial ports + +Configuration and use of the first serial port (SCI) without +interrupts is supported. Input has not yet been tested. + +Configuration of the second serial port (SCIF) is supported. FIFO +handling infrastructure has been started but is not completed yet. + + + GPIO ports + +GPIO ports have been implemented. A registration function allows +external modules to register interest in some port changes (see +hw/tc58128.[ch] for an example) and will be called back. Interrupt +generation is not yet supported but some infrastructure is in place +for this purpose. Note that in the current model a peripheral module +cannot directly simulate a H->L->H input port transition and have an +interrupt generated on the low level. + + + TC58128 NAND flash + +TC58128 NAND flash is partially implemented through GPIO ports. It +supports reading from flash. + +GDB +--- + +GDB remote target support has been implemented and lightly tested. + +Files +----- + +File names are harcoded at this time. The bootloader must be stored in +shix_bios.bin in the current directory. The initial Linux image must +be stored in shix_linux_nand.bin in the current directory in NAND +format. Test files can be obtained from +http://perso.enst.fr/~polti/robot/ as well as the various datasheets I +use. + +qemu disk parameter on the command line is unused. You can supply any +existing image and it will be ignored. As the goal is to simulate an +embedded target, it is not clear how this parameter will be handled in +the future. + +To build an ELF kernel image from the NAND image, 16 bytes have to be +stripped off the end of every 528 bytes, keeping only 512 of them. The +following Python code snippet does it: + +#! /usr/bin/python + +def denand (infd, outfd): + while True: + d = infd.read (528) + if not d: return + outfd.write (d[:512]) + +if __name__ == '__main__': + import sys + denand (open (sys.argv[1], 'rb'), + open (sys.argv[2], 'wb')) + +Style isssues +------------- + +There is currently a mix between my style (space before opening +parenthesis) and qemu style. This will be resolved before final +integration is proposed. @@ -4863,6 +4863,8 @@ void register_machines(void) qemu_register_machine(&integratorcp926_machine); qemu_register_machine(&integratorcp1026_machine); qemu_register_machine(&versatilepb_machine); +#elif defined(TARGET_SH4) + qemu_register_machine(&shix_machine); #else #error unsupported CPU #endif @@ -842,6 +842,9 @@ extern QEMUMachine heathrow_machine; /* mips_r4k.c */ extern QEMUMachine mips_machine; +/* shix.c */ +extern QEMUMachine shix_machine; + #ifdef TARGET_PPC ppc_tb_t *cpu_ppc_tb_init (CPUState *env, uint32_t freq); #endif @@ -1016,6 +1019,28 @@ void *pl190_init(uint32_t base, void *parent, int irq, int fiq); void sp804_init(uint32_t base, void *pic, int irq); void icp_pit_init(uint32_t base, void *pic, int irq); +/* sh7750.c */ +struct SH7750State; + +struct SH7750State *sh7750_init(CPUSH4State * cpu); + +typedef struct { + /* The callback will be triggered if any of the designated lines change */ + uint16_t portamask_trigger; + uint16_t portbmask_trigger; + /* Return 0 if no action was taken */ + int (*port_change_cb) (uint16_t porta, uint16_t portb, + uint16_t * periph_pdtra, + uint16_t * periph_portdira, + uint16_t * periph_pdtrb, + uint16_t * periph_portdirb); +} sh7750_io_device; + +int sh7750_register_io_device(struct SH7750State *s, + sh7750_io_device * device); +/* tc58128.c */ +int tc58128_init(struct SH7750State *s, char *zone1, char *zone2); + #endif /* defined(QEMU_TOOL) */ /* monitor.c */ |
