2009-09-21nfs: initialize the backing_dev_info when creating the serverJens Axboe1-4/+6
NFS may free the server structure without ever having used the bdi, so we either need to flag the bdi as being uninitialized or initialize it up front. This does the latter. This fixes a crash with mounting more than one NFS file system, should people ever need that kind of obscure NFS functionality.

2009-09-21drm/vgaarb: add VGA arbitration support to the drm and kms.Dave Airlie13-1/+133
VGA arb requires DRM support for non-kms drivers, to turn on/off irqs when disabling the mem/io regions. VGA arb requires KMS support for GPUs where we can turn off VGA decoding. Currently we know how to do this for intel and radeon kms drivers, which allows them to be removed from the arbiter. This patch comes from Fedora rawhide kernel.

2009-09-20x86: Print the hypervisor returned tsc_khz during bootAlok Kataria1-0/+6
On an AMD-64 system the processor frequency that is printed during system boot, may be different than the tsc frequency that was returned by the hypervisor, due to the value returned from calibrate_cpu. For debugging timekeeping or other related issues it might be better to get the tsc_khz value returned by the hypervisor. The patch below now prints the tsc frequency that the VMware hypervisor returned.

2009-09-20perf util: SVG performance improvementsArjan van de Ven1-23/+55
Tweak the output SVG to increase performance in SVG viewers by limiting the different types of font sizes and by smarter transformations on the text. At least with Inkscape this gives a notable performance improvement during zoom and scrolling.

2009-09-20perf util: Make the timechart SVG width dynamicArjan van de Ven4-14/+31
This patch adds a command line option for timechart that allows the user to specify the width of the SVG file. This patch also makes sure that each second of recording has at least 200 units (pixels at 96 DPI) of width. This impacts recordings longer than 5 seconds; recordings shorter than 5 second will scale up to have a width of 1000 units for the whole recording (as before).

2009-09-20perf timechart: Show the duration of scheduler delays in the SVGArjan van de Ven3-8/+57
Given that scheduler latencies are the hot thing nowadays, show the duration of said latencies in the SVG in text form. In addition, if the latency is more than 10 msec, pick a brighter yellow color as a way to point these long delays out.

2009-09-20perf timechart: Show the name of the waker/wakee in timechartArjan van de Ven3-11/+30
Timechart currently shows thin green lines for sending or receiving wakeups. This patch also prints (in a very small font) the name of the process that is being woken/wakes up this process.
