[PATCH 3/3 V3] input: STMPE811 touch controller support
This one adds a driver for STMPE811 4-wire resistive touchscreen controller. STMPE811 is a multifunction device. Hence this driver depends on stmpe811_core driver for core functionalities. Signed-off-by: Luotao Fu <l.fu(a)pengutronix.de> --- V2 Changes: * include subsystem headers since they are now remove from t... 15 Jun 2010 05:25

Patch serie for STMPE811 [V3]
Hi, in the following is the V3 patch serie for the stmpe811 chip. Main changes are: * reformat platform data comments to kernel-doc style * add bus_lock/unlock callbacks to the core irq_chip. * move declaration of gpio platform data into the gpio subdevice patch. * new irq flags in the core platform data. etc.... 15 Jun 2010 05:25

TSC reset compensation
On 06/15/2010 10:34 AM, Zachary Amsden wrote: Attempt to synchronize TSCs which are reset to the same value. In the case of a reliable hardware TSC, we can just re-use the same offset, but on non-reliable hardware, we can get closer by adjusting the offset to match the elapsed time.

Fix a possible backwards warp of kvmclock
On 06/15/2010 10:34 AM, Zachary Amsden wrote: Kernel time, which advances in discrete steps may progress much slower than TSC. As a result, when kvmclock is adjusted to a new base, the apparent time to the guest, which runs at a much higher, nsec scaled rate based on the current TSC, may have already been ... 14 Jul 2010 23:06

Add TSC offset tracking
On 06/15/2010 10:34 AM, Zachary Amsden wrote: Track the last TSC offset set for each VM and ensure that the storing of the offset and the reading of the TSC are never preempted by taking a spinlock. Totally missing the point - tsc is per vcpu, why do we need per-vm tracking? -- error compilin... 15 Jun 2010 05:25

Keep SMP VMs more in sync on unstable TSC
On 06/15/2010 10:34 AM, Zachary Amsden wrote: SMP VMs on machines with unstable TSC have their TSC offset adjusted by the local offset delta from last measurement. This does not take into account how long it has been since the measurement, leading to drift. Minimize the drift by accounting for any time di... 14 Jul 2010 23:05
