Subject: PCI Express MSI in kernel 2.4 ?

hello,

I saw that there is an implementation of MSI in the Linux kernel 2.6 stream.

Is there a possibility to port this in the 2.4 kernel tree (we are at
this time using 2.4.17) ?

Is this already foreseen and planned and when ?

Is this MSI feature already used out there ? on which target processor
and southbridge ?


Please CC me ( mailto:[email protected] )since I am not
subscribed to the mail list.

Regards

Philippe

There is no patch for 2.4 and we have no plans to do one.

Chipsets have been shipping with MSI support for several years. The
major dependency is if the PCI card you want to enable supports MSI.
