Need Info about IDE driver

Need Info about IDE driver

[Sachin Rane]

 
Hi,
 
I am new to  'IDE' Linux driver.
Before writing this mail I tried to get information from internet but
couldn't hit the website which can give developer point of view
information.
 
I am going through the code '
kernel-2.6.16.1-ts.amcc440gx.basic.1/drivers/ide/pci/siimage.c' and user
manual for 'Sil0680' to understand how the IDE driver works.

I have very basic questions:
1. What does mean the value '2' i.e. 'Custom' which has been set for
'hwif->mmio'
 
2. Where I can find details about 'TaskFile'?

  
Regards,
Sachin Rane

Hi Sachin,

To make sure you're now going down the wrong path, please be advised
that the 'IDE' drivers are no longer under active development and
are getting replaced by the 'libata' subsystem. You should be looking
at drivers/ata/pata_sil680.c and possibly stat_sil*.c.

Also, note that 2.6.16 is very old and any work you invest there is
probably wasted, so look at the latest version 2.6.31 or 2.6.32.

'Custom' value is gone in newer kernels and it is rather unlikely that you'll
find people interested in the community support for 3.5 years old kernel.

to Linux ATA support.
