Function Documentation

static void cuda_irq_listen

(

void

)

[static]

Interrupt in listen state.

Start packet reception.

Definition at line 324 of file cuda_adb.c.

static void cuda_irq_rcv_end	(	void *	buf,
		size_t *	len
	)			[static]

Interrupt in rcv_end state.

Terminate packet reception. Either go back to listen state or start receiving another packet if CUDA has one for us.

Definition at line 367 of file cuda_adb.c.

static void cuda_irq_receive

(

void

)

[static]

Interrupt in receive state.

Receive next byte of packet.

Definition at line 344 of file cuda_adb.c.

static void cuda_irq_send

(

void

)

[static]

Interrupt in send state.

Send next byte or terminate transmission.

Definition at line 417 of file cuda_adb.c.

static void cuda_irq_send_start

(

void

)

[static]

Interrupt in send_start state.

Process result of sending first byte (and send second on success).

Definition at line 391 of file cuda_adb.c.

uint16_t fb_font_glyph

(

const wchar_t

ch

)

Convert character to font glyph index.

The font does not cover all Unicode characters. This function converts the character to an appropriate glyph in the font or returns an index to the question mark glyph if no specific glyph exists.

Definition at line 46 of file font-8x16.c.

int main	(	int	argc,
		char *	argv[]
	)

Main entry point.

Parameters:

[in]	argc	Nmber of arguments in argv vector (ignored).
[in]	argv	Cmdline argument vector (ignored).

Returns:

Error code.

Driver debug level is set here.

Definition at line 143 of file cuda_adb.c.
