ABOUT:
|
||||
|
||||
This utility will help to create irq_table.c file, that is very hard to create manually,
|
||||
specialy when you are testing new motherboards, changing your hardware often, placing new cards, etc..
|
||||
|
||||
|
||||
INSTALL:
|
||||
|
||||
edit Makefile, define the root to Linuxbios tree
|
||||
make
|
||||
|
||||
USAGE:
|
||||
|
||||
./getpir
|
||||
|
||||
Will dump irq table to the file called irq_tables.c, ready to use with Linuxbios. Just move the
|
||||
file to corresponding place in the linux bios tree.
|
||||
|
||||
|
||||
CHECKING CUSTOM irq_tables.c:
|
||||
|
||||
checkpir.c Will verify the irq_tables.c, currently it only checks the checksum. In case of wrong
|
||||
checksum, a good value is proposed, so you can edit irq_tables.c manualy and replace checksum.
|
||||
Run the command like this:
|
||||
|
||||
make test
|
||||
|
||||
Do not run ./checkpir directly because it needs to be linked to irq_table.o first.
