The unload() function is not very relevant for drivers because hardware state is managed by ctx_save() and ctx_restore() and software state is managed by underlying drivers when there are dependencies. For now, it's been replaced with a wait() function that allows drivers to not be interrupted at any point. It is currently used by the DMA to wait for ongoing transfers to finish before disabling interrupts (which would prevent the transfer end from being detected) and switching in and out of gint.

For the 2.0.0 release:
|
|
* bopti: remove image_t, leaving only bopti_image_t
|
|
* project: remove the compat branch
|
|
* gray: remove g*() functions
|
|
|
|
Crucial, missing things.
|
|
! core: the four basic memory functions (with automated tests)
|
|
! core: use gint_switch() to handle TLB misses
|
|
! core: return to menu on fxcg50
|
|
! syscalls: fxcg50 BFile calls
|
|
|
|
Issues.
|
|
* #3 make drawing functions parameterized
|
|
* #5 add decent random number generation (TinyMT)
|
|
* #8 support fx-CG Manager
|
|
* #10 support fx-CG 20
|
|
|
|
Complementary elements on existing code.
|
|
* gray: double-buffer gray settings and unify d* with g*
|
|
* display: deprecate image_t and rename it bopti_image_t
|
|
* topti: support unicode fonts
|
|
* gray: find good values for more models than the Graph 35+E II
|
|
* dma: maybe relax the 4-byte size constraint for dma_memset()
|
|
* dma: fx9860g support (need to switch it on and update the Makefile)
|
|
* core: try to leave add-in without reset in case of panic
|
|
* hardware: fill in the HWMEM_FITTLB flag
|
|
* keyboard: think of extended functions
|
|
* cpg: spread spectrum on fxcg50
|
|
* display: use more of topti's assembler in drect()
|
|
* core: use cmp/str for memchr()
|
|
* r61524: brightness control and clean the file
|
|
* t6k11: check if dupdate() can be done by the DMA
|
|
|
|
Keep in mind.
|
|
* build: make the build system simpler (two targets are enough by default)
|
|
* core: run destructors when a task-switch results in leaving the app
|
|
* core: invoke main menu instead of returning after main() ends
|
|
* prizm: don't hardcode stack address in fxcg50.ld
|
|
* prizm: detect P1 static RAM (stack) in TLB
|
|
* core rtc: use qdiv10 to massively improve division performance
|
|
* 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.
|
|
* A complete file system abstraction
|
|
* Integrate overclock management
|
|
* Audio playback using Martin Poupe's method
|
|
* Serial communication [SCIF] [SCIFA]
|
|
* USB communication [USB]
|
|
* Make fx9860g projects work out of the box on fxcg50
