* Now uses topti instead of fxlib for text (including MMU failure) * Fit .pretext into 4k for everything before MMU succeeds * A short version of sprintf() for dynamic messages * Support a driver function, status(), to allow early driver debug * Expose more useful platform information in <gint/mpu.h> * Expose the first of a few CASIOWIN syscalls

On the bootlog.
|
|
* Better review of .pretext to make sure everything fits in 4k
|
|
* Move topti to .pretext to use it in the bootlog, also update() and dclear()
|
|
* Use topti in the error message for the missing mappings (hurray o/)
|
|
* Use a serious formatted printing function
|
|
|
|
Crucial, missing things.
|
|
! core: the four basic memory functions
|
|
! core: build an exception handler and a TLB miss handler
|
|
! core: gint_switch() (driver contexts on stack; arbitrary code?)
|
|
|
|
Tests to run.
|
|
* core: run the alignment/size automated tests
|
|
* bopti: more sizes, gray
|
|
* topti: all charsets, colors
|
|
|
|
Completeness elements on existing code.
|
|
* keyboard: finish the interface
|
|
* clock: spread spectrum on fxcg50
|
|
* bopti: blending modes for monochrome bitmaps (use topti assembler)
|
|
* display: use more of topti's assembler in drect()
|
|
* core: use cmp/str for memchr()
|
|
* stdio: serious formatted printing function
|
|
* timer: try putting the definitions in <gint/mpu/tmu.h>
|
|
|
|
Keep in mind.
|
|
* keyboard: make keysc.c@state static and review globals in the project
|
|
* prizm: don't hardcode stack address in fxcg50.ld
|
|
* prizm: detect P1 static RAM (stack) in TLB
|
|
* core: prove and use qdiv10() instead of __sdivsi3
|
|
* setjmp: more registers may need to be saved
|
|
* core: free heap when a task-switch results in leaving the app
|
|
* core: save and restore interrupt masks
|
|
* timer: make sure ETMU interrupts are disabled in ctx_restore()
|
|
* core: document the SH7305 PFC in <gint/mpu/pfc.h>
|
|
|
|
Future directions.
|
|
* File management
|
|
* Gray engine
|
|
* Integrate overclock management
|
|
* A library for profiling with manual calls
|
|
* Audio playback using Martin Poupe's method
|
|
* Serial communication [SCIF] [SCIFA]
|
|
* USB communication [USB]
|
|
* Driver for the watchdog timer [WDT] [SH7705]
