Member Data Documentation

AllocPipe

dd usb_hardware_func::AllocPipe

in: esi -> usb_controller, ebx -> usb_pipe, ecx = packet size

AllocTD

dd usb_hardware_func::AllocTD

esi -> usb_controller, ebx -> usb_pipe

AllocTransfer

dd usb_hardware_func::AllocTransfer

void stdcall with one argument = pointer to previously allocated usb_gtd

BeforeInit

dd usb_hardware_func::BeforeInit

DataSize

dd usb_hardware_func::DataSize

sizeof(*hci_controller)

DisablePipe

dd usb_hardware_func::DisablePipe

Initiate configuration of a new device (create pseudo-pipe describing that device and call usb_new_device). esi -> usb_controller, eax = speed (one of USB_SPEED_* constants).

EnablePipe

dd usb_hardware_func::EnablePipe

This procedure temporarily removes the given pipe from hardware queue. esi -> usb_controller, ebx -> usb_pipe

FreePipe

dd usb_hardware_func::FreePipe

out: eax = pointer to allocated usb_pipe

FreeTD

dd usb_hardware_func::FreeTD

out: eax = pointer to allocated usb_gtd

GetDeviceAddress

dd usb_hardware_func::GetDeviceAddress

in: esi -> usb_controller, ebx -> usb_pipe, cl = address

ID

dd usb_hardware_func::ID

'*HCI'

Init

dd usb_hardware_func::Init

Early initialization: take ownership from BIOS. in: [ebp-4] = (bus shl 8) + devfn

InitiateReset

dd usb_hardware_func::InitiateReset

Disable the given port in the root hub. in: esi -> usb_controller, ecx = port (zero-based)

InitPipe

dd usb_hardware_func::InitPipe

void stdcall with one argument = pointer to previously allocated usb_pipe

InsertTransfer

dd usb_hardware_func::InsertTransfer

Allocate and initialize one stage of a transfer. ebx -> usb_pipe, other parameters are passed through the stack: buffer,size = data to transfer flags = same as in usb_open_pipe: bit 0 = allow short transfer, other bits reserved td = pointer to the current end-of-queue descriptor direction = 0000b for normal transfers, 1000b for control SETUP transfer, 1101b for control OUT transfer, 1110b for control IN transfer returns eax = pointer to the new end-of-queue descriptor (not included in the queue itself) or 0 on error

NewDevice

dd usb_hardware_func::NewDevice

Activate previously initialized transfer (maybe with multiple stages). esi -> usb_controller, ebx -> usb_pipe, [esp+4] -> first usb_gtd for the transfer, ecx -> last descriptor for the transfer

PortDisable

dd usb_hardware_func::PortDisable

in: esi -> usb_controller, ebx -> usb_pipe out: eax = address

ProcessDeferred

dd usb_hardware_func::ProcessDeferred

Initialize controller-specific part of controller data. in: eax -> *hci_controller to initialize, [ebp-4] = (bus shl 8) + devfn out: eax = 0 <=> failed, otherwise eax -> usb_controller

SetDeviceAddress

dd usb_hardware_func::SetDeviceAddress

Called regularly from the main loop of USB thread (either due to timeout from a previous call, or due to explicit wakeup). in: esi -> usb_controller out: eax = maximum timeout for next call (-1 = infinity)

SetEndpointPacketSize

dd usb_hardware_func::SetEndpointPacketSize

Start reset signalling on the given port. in: esi -> usb_controller, ecx = port (zero-based)

UnlinkPipe

dd usb_hardware_func::UnlinkPipe

in: edi -> usb_pipe for target, ecx -> usb_pipe for config pipe, esi -> usb_controller, eax -> usb_gtd for the first TD, [ebp+12] = endpoint, [ebp+16] = maxpacket, [ebp+20] = type

Version

dd usb_hardware_func::Version

must be USBHC_VERSION
