In +this case though we're enabling 64bit DMA for the Asus M3A motherboard. It +is a new enough board that all of the BIOS releases since the initial +release (0301 from 2007-10-22) work correctly with 64bit DMA enabled. + +Signed-off-by: Mark Nelson <mdnelson8@gmail.com> +Signed-off-by: Jeff Garzik <jgarzik@pobox.com> +Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> + +--- + drivers/ata/ahci.c | 12 ++++++++++++ + 1 file changed, 12 insertions(+) + +--- a/drivers/ata/ahci.c ++++ b/drivers/ata/ahci.c +@@ -2769,6 +2769,18 @@ static bool ahci_sb600_enable_64bit(stru + DMI_MATCH(DMI_BOARD_NAME, "MS-7376"), + }, + }, ++ /* ++ * All BIOS versions for the Asus M3A support 64bit DMA. ++ * (all release versions from 0301 to 1206 were tested) ++ */ ++ { ++ .ident = "ASUS M3A", ++ .matches = { ++ DMI_MATCH(DMI_BOARD_VENDOR, ++ "ASUSTeK Computer INC."), ++ DMI_MATCH(DMI_BOARD_NAME, "M3A"), ++ }, ++ }, + { } + }; + const struct dmi_system_id *match; diff --git a/queue-2.6.32/series b/queue-2.6.32/series index 9bb10df..7805c7b 100644 --- a/queue-2.6.32/series +++ b/queue-2.6.32/series @@ -43,3 +43,4 @@ libsas-fix-failure-to-revalidate-domain-for-anything-but-the-first-expander-chil cfg80211-fix-validation-of-akm-suites.patch splice-direct_splice_actor-should-not-use-pos-in-sd.patch libsas-fix-panic-when-single-phy-is-disabled-on-a-wide-port.patch +ahci-enable-sb600-64bit-dma-on-asus-m3a.patch |
