Yanko's GA-MA78GM-S2H (BIOS F11) reports a host bridge window that overlaps system memory: PCI window: [mem 0xcff00000-0x10ed0ffff] System RAM: [mem 0x100000000-0x22fffffff] We can be pretty confident that the System RAM region is correct (if it were wrong, we'd crash as soon as we tried to use any m... 11 Mar 2010 20:13

[PATCH] firmware class: export nowait to userspace
When we use request_firmware_nowait(), userspace may not want to answer negatively right away when for example it is answering from an initrd only, but with request_firmware() it has to in order to not delay the kernel boot until the request times out. This allows userspace to differentiate between the two in o... 11 Mar 2010 19:06
