Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

9 | This allows device drivers to enable MSI (Message Signaled | ||
10 | Interrupts). Message Signaled Interrupts enable a device to | ||
11 | generate an interrupt using an inbound Memory Write on its | ||
12 | PCI bus instead of asserting a device IRQ pin. | ||
13 | |||
14 | If you don't know what to do here, say N. | ||

16 | config PCI_LEGACY_PROC | ||
17 | bool "Legacy /proc/pci interface" | ||
18 | depends on PCI | ||
19 | ---help--- | ||
20 | This feature enables a procfs file -- /proc/pci -- that provides a | ||
21 | summary of PCI devices in the system. | ||
22 | |||
23 | This feature has been deprecated as of v2.5.53, in favor of using the | ||
24 | tool lspci(8). This feature may be removed at a future date. | ||
25 | |||
26 | lspci can provide the same data, as well as much more. lspci is a part of | ||
27 | the pci-utils package, which should be installed by your distribution. | ||
28 | See <file:Documentation/Changes> for information on where to get the latest | ||
29 | version. | ||
30 | |||
31 | When in doubt, say N. | ||
32 | |||
33 | config PCI_NAMES | ||
34 | bool "PCI device name database" | ||
35 | depends on PCI | ||
36 | ---help--- | ||
37 | By default, the kernel contains a database of all known PCI device | ||
38 | names to make the information in /proc/pci, /proc/ioports and | ||
39 | similar files comprehensible to the user. | ||
40 | |||
41 | This database increases size of the kernel image by about 80KB. This | ||
42 | memory is freed after the system boots up if CONFIG_HOTPLUG is not set. | ||
43 | |||
44 | Anyway, if you are building an installation floppy or kernel for an | ||
45 | embedded system where kernel image size really matters, you can disable | ||
46 | this feature and you'll get device ID numbers instead of names. | ||
47 | |||
48 | When in doubt, say Y. | ||
49 | |||
50 | config PCI_DEBUG | ||
51 | bool "PCI Debugging" | ||
52 | depends on PCI && DEBUG_KERNEL | ||
53 | help | ||
54 | Say Y here if you want the PCI core to produce a bunch of debug | ||
55 | messages to the system log. Select this if you are having a | ||
56 | problem with PCI support and want to see more of what is going on. | ||
