Hi all, There is a problem with the ck804 code in the tree when it comes to SATA support. I've observed this on a tyan s2891, and it has been confirmed by folks with a sun ultra40.
This patch changes the southbridge/nvidia/ck804/ck804_early_setup.c file and enables one extra SATA port. I've tested this on real hardware (tyan s2891). There is a very similar file called southbridge/nvidia/ck804/ck804_early_setup_car.c which seems to be used by tyan/s2895 sunw/ultra40 I don't have access to a s2895, but YH thinks that all sata ports should work on that board. It would be great if someone could verify that. I'm not 100% sure why both the ck804_early_setup.c and the ck804_early_setup_car.c file are included in the mainboards/sunw/ultra40/ tree; probably only one of those files is actually used. I've spent quite a bit of time with 'dumpio' and tried to match register values between the proprietary BIOS and LinuxBIOS, but to no avail. If someone has ideas to get port 1 working on both sata controllers, that would be great. Thanks, Ward. -- Ward Vandewege <[EMAIL PROTECTED]> Free Software Foundation - Senior System Administrator
The ck804 code in the LB tree does not properly initialize all SATA ports. The situation is currently as follows for boards with 4 SATA ports: * sata controller 0: both ports 100% dead (no drives detected) * sata controller 1: port 0 ok; port 1 sees drive but times out when trying to access it The attached patch fixes port 0 on controller 0; port 1 on both controllers is still half-broken (as in it sees the drive initially but times out when trying to access it). This patch will affect the boards that use the southbridge/nvidia/ck804/ck804_early_setup.c file: sunw/ultra40 tyan/s2891 tyan/s2892 asus/a8n_e Signed-off-by: Ward Vandewege <[EMAIL PROTECTED]> Index: ck804_early_setup.c =================================================================== --- LinuxBIOSv2/src/southbridge/nvidia/ck804/ck804_early_setup.c (revision 2974) +++ LinuxBIOSv2/src/southbridge/nvidia/ck804/ck804_early_setup.c (working copy) @@ -228,6 +228,18 @@ RES_PORT_IO_32, CK804B_ANACTRL_IO_BASE + 0x24, 0xfcffff0f, 0x020000b0, #endif + // Activate master port on primary SATA controller + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0x50), ~(0x1f000013), 0x15000013, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0x64), ~(0x00000001), 0x00000001, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0x68), ~(0x02000000), 0x02000000, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0x70), ~(0x000f0000), 0x00040000, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0xa0), ~(0x000001ff), 0x00000150, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0xac), ~(0xffff8f00), 0x02aa8b00, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0x7c), ~(0x00000010), 0x00000000, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0xc8), ~(0x0fff0fff), 0x000a000a, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0xd0), ~(0xf0000000), 0x00000000, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+7 , 0, 0xe0), ~(0xf0000000), 0x00000000, + RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+8 , 0, 0x50), ~(0x1f000013), 0x15000013, RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+8 , 0, 0x64), ~(0x00000001), 0x00000001, RES_PCI_IO, PCI_ADDR(0, CK804_DEVN_BASE+8 , 0, 0x68), ~(0x02000000), 0x02000000,
