Making Xorg easier to test
From: Daniel Stone <daniel(a)fooishbar.org> Date: Fri, 5 Mar 2010 17:41:43 +0200 I understand that you guys are upset about this, so maybe you'd like to donate, say, 10% of your developer base to help out? That'd be pretty ace. You have to support less than %10 of the amount of hardware we have to support... 5 Mar 2010 13:56

[PATCH 0/5] PEBS and LBR fixes
With these patches PEBS also works on my Core2 machines, although sometimes it fails to generate samples for some reason, so there's more errata to read. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http:... 5 Mar 2010 11:40

perf: Introduce new perf_save_regs() for hot regs snapshot
