RE: AMD/ATI SB700 support to Debian
Hi dann,
Without the quirk function for SB600, if the SATA type is set as legacy IDE in the system BIOS,
SATA HDD will not be detected while installing OS.
SB700 also supports legacy IDE mode too, so we need the same quirk function.
Besides the modes in SB600, there is one more mode in SB700, that is combined mode,
this mode combines the SATA and IDE into one mode, technically, it is the same mode as legacy IDE mode,
so, we use the same quirk function for the combined mode in SB700.
we certainly write the different quirk function for the combined mode in SB700, but this quirk function
is the same as SB600's, that is why they share the same quirk function.
Because SB600 and SB700 have different device IDs,and we use these different ID to distinguish the legacy IDE
in SB600 and the combined mode in SB700, so, there is no risk for the SB600 or SB700.
BRs,
Henry

+AD4- +AD4- Do you know of any reason these changes wouldn't work on a 2.6.18

+AD4- +AD4- pointed you to snapshot debs with these changes?
+AD4-
+AD4- I'm sorry that I do not catch your meaning very much because I'm a
+AD4- newbie
+AD4- in Debian, I did not use Debian before and know little about it, the
+AD4- distribution
+AD4- I have being using for some time is Redhat/Fedora. My main task here is
+AD4- to
+AD4- check whether the SB700 patches have been added into the familiar
+AD4- distributions
+AD4- to be released such as Debian 4.1, RHEL5.1 and Fedora 8.
'lenny' is the next major release of Debian (which might be called
4.1). But, that is over a year away whereas adding hardware support to
the existing release (4.0, 'etch') is possible sooner.
+AD4- So could you give me more information about your questions? Such as:
+AD4- What's the function/usage of +ACI-2.6.18 base+ACI-? Why are you still using it
+AD4- if
+AD4- next Debian 4.1 release will use the kernel after 2.6.23-rc1. etc
Debian 'etch' is based on 2.6.18.
+AD4- +AD4- The combined mode patch for sb700 depends on a quirk that was added
+AD4- +AD4- for sb600 after 2.6.18. I could of course backport this quirk only for
+AD4- +AD4- sb700, but is there a good reason for adding it for sb600 as well?
+AD4-
+AD4- I think adding both the SB600 patch and SB700 is better, since the
+AD4- distribution
+AD4- can be used on motherboards with SB600 or SB700.
SB600 support is already there. What I'm saying is that there was a
pci quirk added for the SB600 sometime after 2.6.18, and the SB700
uses the same one. So, since we would, in theory, backport it as part
of the SB700 backport - what is the value/risk of enabling it for the
SB600 as well? We don't want to risk breaking existing SB600 support
in etch unless there's a good reason.
