I'm currently trying to write a device driver for a PCI bridged PCI-Express USB3 XHCI controller and running into the following situation... during ramlib execution of the device "DevInit" and eventually passing through "InitUnit()" I can use the expansion.library "IPCI"...

well... everything I was doing before reworking that section was entirely localized for variable usage.

so I am not actually sure where the globals came from at all

Not a redeemable choice in following the example so closely... changed from using AddTask() over to using CreateTask() [CreateTaskTags() variant] instead... using AddTask() turns out to only be safe as long as code is hand-written assembly at that point. otherwise *every* syscall will trigger DSI an...

@ThomasRapp: Thank you for clarifying that. Will try it and see what happens next... It will be nice to actually have a working XHCI USB3 controller added to my setup ... @Everyone... if anyone wants the sources I'll be publishing them in full as an example device driver, that works against *real* P...

The stack grows downwards from high to low addresses. So to start with an empty stack SPReg must point to the end of the stack, not to the beginning. so then ... unit->uTask.tc_SPReg = (APTR)((uint32)UNIT_STACK_SIZE +(uint32)(unit->uStack)); unit->uTask.tc_SPLower = unit->uStack; unit->uTask.tc_SPU...

What would be the specific corrections needed to deal with the SPReg, SPLower and SPUpper in the "struct Task uTask;" as part of the "struct DEVICE_UNIT_CLASS *unit;" dyamically allocated within the following code ? I'm looking at the example on the Amiga Developer CD 2.1 and try...

EDIT: @Broadblues: Multiple PubScreens with separate GraphicsCard+Monitor hardware *on-a-single-machine*, not two machines sharing a Keyboard+mouse, single machine with two graphics cards and two monitors showing two PubScreens that are used as a singular workspace. Yes but functionally in terms of...

FOR CLARICATION ***NOT** A SINGLE-SCREEN ACROSS MONITORS, Specifically the visual appearance of *multiple* PubScreens allowing the mouse to visually border cross from one to another, @ThomasRapp: the Right-Border linkage to a second screen is a simple case, I was also considering where Workbench was...

This is actually very simple in concept, 1: Allowance for Mutliple Display Capable Machines to have whatever Intuition Screen displayed on each card to continue refreshing even when the pointer is active elsewhere 2 Visually Infinite Mouse Scrolling using a transition at Screen Edges Option (Program...

I have run across a hardware option for RAID that is Amiga compliant (at least for 4.x+)… Logitech do a “Gachabay” branded set of SATA/USB3 Harddisk RAID controllers for the Japanese market, you can slot between 2-8 mixed disks as a single device in a simple JBOD(multiple disks by LUN)/RAID0/… arran...
