I have take a look to the history of changes of hda_intel.f and found that :
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0a27fcfaaf61108d94f0377f91bed81b2dd35f52
in the source I'm seeing a blacklist :
/*
* white/black-list for enable_msi
*/
static struct snd_pci_quirk msi_black_list[] __devinitdata = {
SND_PCI_QUIRK(0x1043, 0x81f2, "ASUS", 0), /* Athlon64 X2 + nvidia */
SND_PCI_QUIRK(0x1043, 0x81f6, "ASUS", 0), /* nvidia */
{}
};
And on my eeepc 1201n there is lot's of nvidia things...How can I know
if I'm on this blacklist or not ? ...sorry, I don't have a lot of
knowledge in C. But this could be explain why msi is not enabled by
default...
Best regards,
Guillaume
