| |
We currently produce a device driver for the 1.2.x and 2.0.x kernels which supports several of our asynchronous boards here at Digi. Recently we added support for our line of PCI cards though this support only extended to the 2.0.x kernel. Since we have many customers still using the older kernels (1.2.x) we would like to make the driver also support PCI under these older kernels.
Currently we use the 'vremap' command (Or 'ioremap' in 2.1.x) to map in high memory addresses such as those typically read from PCI base address registers. Unfortunetly, I do not know the name of the corresponding function in the 1.2.x kernel (If there is such a thing). Sooooo two questions......
If it exist, what is the function called ? Do you know what header files are required ?
Also (So it's 3 questions :-) ), are there any other gotchas to supporting PCI under 1.2.x ?
Thanks for any help !!! Ronnie Sanford Digi International
