ipmi: change device node ordering to reflect probe order

2008-04-04T21:46:26Z

In 2.6.14 a patch was merged which switching the order of the ipmi device naming from in-order-of-discovery over to reverse-order-of-discovery. So on systems with multiple BMC interfaces, the ipmi device names are being created in reverse order relative to how they are discovered on the system (e.g. on an IBM x3950 multinode server with N nodes, the device name for the BMC in the first node is /dev/ipmiN-1 and the device name for the BMC in the last node is /dev/ipmi0, etc.). The problem is caused by the list handling routines chosen in dmi_scan.c. Using list_add() causes the multiple ipmi devices to be added to the device list using a stack-paradigm and so the ipmi driver subsequently pulls them off during initialization in LIFO order. This patch changes the dmi_save_ipmi_device() list handling paradigm to a queue, thereby allowing the ipmi driver to build the ipmi device names in the order in which they are found on the system.

dmi: prevent linked list corruption

2008-02-24T01:12:15Z

Adding the same item to a given linked list more than once is guaranteed to break and corrupt the list. This is however what we do in dmi_scan since commit 79da4721117fcf188b4b007b775738a530f574da ("x86: fix DMI out of memory problems"). Given that there is absolutely no interest in saving empty OEM strings anyway, I propose the simple and efficient fix below: we discard the empty OEM strings altogether.

dmi: don't save the same device twice

2008-02-24T01:12:14Z

Now that we gather on-board devices from both DMI types 10 and 41, there is a possibility that we list the same device twice. In order to not confuse drivers, and also to save memory, make sure that we do not add duplicate devices to the dmi_devices list.

SMBIOS/DMI: add type 41 = Onboard Devices Extended Information

2008-02-08T17:22:37Z

From version 2.6 of the SMBIOS standard, type 10 (On Board Devices Information) becomes obsolete. The reason for this is that no further fields can be added to this structure without adversely affecting existing software's ability to properly parse the data. Therefore type 41 (Onboard Devices Extended Information) was added. The structure is as follows: struct smbios_type_41 { u8 type; u8 length; u16 handle; u8 reference_designation_string; u8 device_type; /* same device type as in type 10 */ u8 device_type_instance; u16 segment_group_number; u8 bus_number; u8 device_function_number; }; For more info: http://www.dmtf.org/standards/smbios Signed-off-by: Wim Van Sebroeck Cc: Jean Delvare Cc: Len Brown Cc: Jeff Garzik Cc: Tejun Heo Cc: Alan Cox Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

dmi: Let drivers walk the DMI table

Let drivers walk the DMI table for their own needs. Some drivers need data stored in OEM-specific DMI records for proper operation. Signed-off-by: Jean Delvare Signed-off-by: Mark M. Hoffman

dcdbas: add DMI-based module autloading

2008-02-06T18:41:01Z

DMI autoload dcdbas on all Dell systems. This looks for BIOS Vendor or System Vendor == Dell, so this should work for systems both Dell-branded and those Dell builds but brands for others. It causes udev to load the dcdbas module at startup, which is used by tools called by HAL for wireless control and backlight control, among other uses. Thanks to Kay Sievers for figuring out how to do this with a single alias. Signed-off-by: Matt Domsch Cc: Kay Sievers Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
