VGADirectController #36

Closed S0urceror closed 6 months ago

S0urceror commented 8 months ago

Do you plan to support the VGADirectController? Would love to use the emulator during development of ElectronHAL/OS. I use VGADirectController to implement the virtual TMS9918 videochip in HAL.

I didn't know it existed, because it was removed from vdp-gl. I'd like to get all agon firmwares running on the emulator, so will definitely look into adding VGADirectController to userspace-vdp-gl

I just pushed VGADirectController support to main. The fabgl example works with some modifications. Most notably the vTaskNotifyGiveFromISR function used to signal vsync isn't implemented. We could look into implementing it, or just #ifdef USERSPACE in your firmware code to do something else that makes sense in the emulated context.

Thx, I'm busy trying to get ElectronHAL/OS running on the emulator. I'll report back here.

Ok, got some success running ElectronOS:

For this I had to do a couple of changes and fixes to the agon and cpu emulator. I made these changes on a separate electron branch which I will commit soon and issue a pull-request.
