hrtimer's only have a cb_mode if CONFIG_HIGH_RES_TIMER is enabled. This patch memset()s the tx_timer structure to 0 which has the same effect as setting cb_mode to HRTIMER_CB_SOFTIRQ without requiring CONFIG_HIGH_RES_TIMER to be set. This seems to be what other drivers do. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> diff --git a/driv...

Hi all :) I''ve tested this and having a cpufreq that slows down the CPU affects the rate of HTB. My ondemand cpufreq governor scales down the CPU frequency about 40% and this is more or less the slowdown the rate suffers, 40%. Any known way of dealing with this without having to disable cpufreq? Thanks in advance :) Ra?l N??ez de Arenas Coronado -- Linux Registered

Hi! i notice a serious regression with 3.5 as Dom0 kernel (3.4 was rock stable): 1st: only the GPU PCI Passthrough works, the PCI USB Controller is not recognized within the DomU (HVM Win7 64) Dom0 cmdline is: ro root=LABEL=dom0root xen-pciback.hide=(08:00.0)(08:00.1)(00:1d.0)(00:1d.1)(00:1d.2)(00:1d.7) security=apparmor noirqdebug nouveau.msi=1 Only 8:00.0 and 8:00.1 get passed through

Hi there, I am getting very low throughput (around 0.29Mbps) while running netperf benchmark for guest to guest communication on a single physical host. To analyse where the time is spent in hypervisor I wanna use profiling. Please help me choosing good profiler according to my requirments. Should it be better in my case, Xentrace, gprof, xenoprof  or Oprofile. Is it possible to use some vtune
