Todo List

Class _NUTTHREADINFO
Sort items while considering alignment.

File s3c4510b_irqreg.c

File bankmem.h
Add configuration items instead of occupying all banks.

Global ms62_5
To be removed.

Group xgThread
Using the special priority 255 to kill a thread is not required and should be removed.

Global GetThreadByName (char *name)
Rarely used helper function. Should be placed in a seperate module.

Global NutThreadExit (void)
NutThreadKill() can be used instead of setting the priority level to 255.

Global NutThreadResume (void)
Removing a single thread from a wait queue only improves context switching, but may result in an event time-out for remaining threads, although events had been posted already.

Global NutThreadSetPriority (u_char level)
Using a specific priority level for killing a thread is actually not the best idea. NutThreadKill() can be used instead.

Global NutThreadWake (HANDLE timer, HANDLE th)
Used by the timer module. Should be moved there, because not all applications will use of NutSleep().

Global NutEventPostFromIrq (qp)
Avoid counter overrun.

Global NutSleep (u_long ms)
Code size can be reduced by trying to create the timer before removing the thread from the run queue.

Global NutTimerCreate (u_long ticks, void(*callback)(HANDLE, void *), void *arg, u_char flags)
Make this local function static or directly integrate it into NutTimerStartTicks().

Global NutTimerInsert (NUTTIMERINFO *tn)
Make this local function static.

Group xgBankMem
At least some parts should be moved to the device section.

Group xgSocket
An ICMP socket API would be nice.

Global NutTcpCreateSocket (void)
Avoid fixed initial sequence number.

Group xgUdpSocket
There is no similar call like NutTcpError() available for UDP.

Group xgBasePro
IGMP support.

Group xgTCP
Use an indirect call for NutTcpInput(). Right now, the whole TCP code is linked to any application, even if only UDP is used.

Group xgIP
Configurable checksum calculation for incoming datagrams.

Group xgARP
Add functions to manually add or remove ARP entries.

Add function to query ARP tables.

Group xgARP
Response may reuse received ARP packet.

Group xgEthernet
Multicast support.

Group xgUserPro
Adding more protocols would be helpful, e.g. SMTP. Right now, applications must implement them with the Socket API.

Global NutDhcpClient (void *arg)
We are using a bunch of global variables, which must be associated to a specific interfase if we want to support more than one Ethernet port.

Global NutGetMimeHandler (char *name)
Function to register additional mime types. Currently only .txt, .html, .gif and .jpg are supported.

Global NutGetMimeType (char *name)
Function to register additional mime types. Currently only .txt, .html, .gif and .jpg are supported.

Global NutSetMimeHandler (char *extension, void(*handler)(FILE *stream, int fd, int file_len, char *http_root, REQUEST *req))
Function to register additional mime types. Currently only .txt, .html, .gif and .jpg are supported.

Group xgSntp
Enhance documentation.

Global UsartClose (NUTFILE *fp)
We may support shared open and use dev_irq as an open counter.

Global UsartInit (NUTDEVICE *dev)
Read initial settings from EEPROM.

Global UsartOpen (NUTDEVICE *dev, CONST char *name, int mode, int acc)
We may support shared open and use dev_irq as an open counter.

Global TermWrite (NUTFILE *fp, CONST void *buffer, int len)
TAB should be interpreted.

Global MmCardIOCtl (NUTDEVICE *dev, int req, void *conf)
Card change detection should verify the serial card number.

Global SbiMmCard0Avail (void)
Card change should verify the card identifier. Right now any detection of removing and re-inserting a card counts as a card change.

Global SbiMmCard0WrProt (void)
Not implemented.

Global NutWatchDogStart (u_long ms, u_long xmode)
AVR implementation.

Global NplMmCard0Avail (void)
Card change should verify the card identifier. Right now any detection of removing and re-inserting a card counts as a card change.

Global NplMmCard0WrProt (void)
Not implemented.

Global NUTMEM_END
Shall we support NUTRAMEND for backward compatibility? If, then let's do it in cfg/memory.h.

Global NutInit (void)
Make heap threshold configurable, currently hardcoded at 384.

Make wait states for external memory access configuratble.

Make early UART initialization for kernel debugging configurable.

Global AhdlcAvrClose (NUTFILE *fp)
We may support shared open and use dev_irq as an open counter.

Global NutRegisterTimer (void(*handler)(void *))
Hardware stuff to be put in nutlibdev.

Group xgNutArchArmDevIrqAt91
Handle AT91 interrupts nicely.

Global At91SpiMmCard0Avail (void)
Card change should verify the card identifier. Right now any detection of removing and re-inserting a card counts as a card change.

Global At91SpiMmCard0WrProt (void)
Not implemented.

Global EmacOutput (NUTDEVICE *dev, NETBUF *nb)
This routine does not work.
