Author: hbelusca Date: Sat Nov 9 22:15:40 2013 New Revision: 60907 URL: http://svn.reactos.org/svn/reactos?rev=60907&view=rev Log: [NTVDM] Start my work on modularizing registration of "32-bit" interrupts, i.e. interrupts that are implemented in 32-bit mode, but are stubbed with 16-bit code (so that 16-bit apps can call them). The 16-bit stub code uses a BOP call to our Control BOP function (BOP 0xFF) which can handle in theory many sub-functions (as the BOP 0x58 documented here: http://www.ragestorm.net/tutorial?id=27) specified as an additional BYTE in the call: 0xC4 0xC4 bop_code <optional_bop_subfunction> Here, for calling 32-bit interrupts we use our BOP 0xFF, subfunction 0xFF. The final aim would be to generate the 16-bit stub code when one calls the RegisterInt32 helper function (contrary to what's happening now, that is, the 16-bit stub code is generated for all of the interrupts at BIOS initialization time, and we use it for BIOS and DOS interrupts).
