(коротко) Describe your order in free form: What application do you need: [---] web-site: OS2FAQ/?action=devdrv your contacts * email: [---] Development of device drivers Detailed information: Network drivers File systems USB drivers Print drivers Template of 32-bit driver for eComStation Download eCo Software simple 32-bit driver. 32-bit driver interaction with ACPI driver KEE interface To develop modern drivers you should use DevHlp, KEE interfaces. Read DDK, pddref.inf for details. Description of KEE interface KEE Interface - The KEE extensions provide modified kernel entry points into the stack. This helps give the stack faster access to kernel services like locks and memory allocation. (History: KEE was invented for JFS and TCP/IP 4.4) kee.zip, keeapi.zip Tutorials We recommend start from this presentation: OS/2 Device Driver Programming by Daniela Engert, (includes snippets of code) From Hello World to Real World Part 1: The Driver Part 2: Putting your driver to work Part 3: Passing Your Own Data To and From Your Device Driver Part 4: Writing a Device Driver for your own Data Acquisition Card Part 5: Making I/O Calls Part 6: Interrupt Processing Suspend/resume eCS supports suspend/resume for one-core and multi-core desktops and notebooks. You can use APM interface (read DDK -> in_out.inf, Input/Output Device Driver Reference) or hidden kernel function SaveRestore() /* * Function SaveRestore * @pkt standard drivers packet * @return None * Note: This function is undocemmented in pddref.inf */ void SaveRestore( PRPSAVERESTORE pkt) { PrintDevCall((PRPH)pkt, "SaveRestore"); if (PSD) { PSD->AcpiOsPrintf("APM:SaveRestore - %x\n",(ULONG)pkt->FuncCode); } pkt->rph.Status |= STDON; } dd OFFSET FLAT:SaveRestore ; Command code 20h SaveRestore   Please share information with other developers how to: How to process command line parameters? How to gather log, so user can call: copy acpica$ acpi.log How to register driver in resource manager? So users can see it via rmview /IRQ Programming PCI devices To create new driver, you need PCI standard (PCI Specifications Documents) Datasheet for your device Use OEMHLP$ to work with PCI. Useful functions Additional information: Writing PCI device drivers Wakeup PCI devices Examples: Wake up sleeping PCI devices at boot time (by Veit) driver, source code Source code of USB drivers (DDK) Read/write ports from Ring3 Example how to read/write to the ports Mapping physical memory to linear Use this method (via SCREEN$) memory mapping via SCREEN$ (thx LightElf) Driver debugging if you are going to do driver debugging, a trap dump partition is a must have. It will save you a lot of time. A usable kernel debugger setup will save you a even more time, but this can be problematic on newer systems that lack a serial port.
