intel_pstate: Correct calculation of min pstate value

2014-02-13T21:48:04Z

commit 7244cb62d96e735847dc9d08f870550df896898c upstream. The minimum pstate is supposed to be a percentage of the maximum P state available. Calculate min using max pstate and not the current max which may have been limited by the user Signed-off-by: Dirk Brandewie Signed-off-by: Rafael J. Wysocki Signed-off-by: Greg Kroah-Hartman

intel_pstate: Improve accuracy by not truncating until final result

2014-02-13T21:48:04Z

commit d253d2a52676cfa3d89b8f0737a08ce7db665207 upstream. This patch addresses Bug 60727 (https://bugzilla.kernel.org/show_bug.cgi?id=60727) which was due to the truncation of intermediate values in the calculations, which causes the code to consistently underestimate the current cpu frequency, specifically 100% cpu utilization was truncated down to the setpoint of 97%. This patch fixes the problem by keeping the results of all intermediate calculations as fixed point numbers rather scaling them back and forth between integers and fixed point.

intel_pstate: fix no_turbo

2014-02-13T21:48:04Z

commit 1ccf7a1cdafadd02e33e8f3d74370685a0600ec6 upstream. When sysfs for no_turbo is set, then also some p states in turbo regions are observed. This patch will set IDA Engage bit when no_turbo is set to explicitly disengage turbo. Signed-off-by: Srinivas Pandruvada Acked-by: Dirk Brandewie Signed-off-by: Rafael J.

intel_pstate: Add Haswell CPU models

2014-02-13T21:48:04Z

commit 6cdcdb793791f776ea9408581b1242b636d43b37 upstream. Enable the intel_pstate driver for Haswell CPUs. One missing Ivy Bridge model (0x3E) is also included.

rtc-cmos: Add an alarm disable quirk

2014-02-13T21:48:03Z

commit d5a1c7e3fc38d9c7d629e1e47f32f863acbdec3d upstream. 41c7f7424259f ("rtc: Disable the alarm in the hardware (v2)") added the functionality to disable the RTC wake alarm when shutting down the box. However, there are at least two b0rked BIOSes we know about: https://bugzilla.novell.com/show_bug.cgi?id=812592 https://bugzilla.novell.com/show_bug.cgi?id=805740 where, when wakeup alarm is enabled in the BIOS, the machine reboots automatically right after shutdown, regardless of what wakeup time is programmed. Bisecting the issue lead to this patch so disable its functionality with a DMI quirk only for those boxes.

drm/cirrus: correct register values for 16bpp

2014-02-13T21:48:03Z

commit 2510538fa000dd13a3e57b79bf073ffb1748976c upstream. When the mode is set with 16bpp on QEMU, the output gets totally broken. The culprit is the bogus register values set for 16bpp, which was likely copied from from a wrong place.
