[Xen-devel] [PATCH RFC 52/59] libxl: Implement Bitmap.String()

From: George Dunlap Implement Bitmap.String, which will convert a bitmap into a string parse-able by libxl. Signed-off-by: George Dunlap --- libxl.go | 59 ++- 1 file changed, 58

[Xen-devel] [PATCH RFC 11/59] Refactor to move towards benchmark "plans" and data analysis

From: George Dunlap A bit of a roll-up of lots of bits. Signed-off-by: George Dunlap --- Makefile | 4 +- benchmark.go | 256 +++ main.go | 197

[Xen-devel] [PATCH RFC 12/59] Basic 'report' functionality

From: George Dunlap Go through the raw data and re-calculate throughput for each timeframe. Record for each worker the min and max of these; then take an average over the whole run. Have the report go through each and show the worker setup, as well as the avg, min,

[Xen-devel] [PATCH RFC 21/59] Report utilization statistics

From: George Dunlap Refactor the min/max into a separate type. Signed-off-by: George Dunlap --- benchmark.go | 119 +-- run.go | 4 +- 2 files changed, 78 insertions(+), 45

[Xen-devel] [PATCH RFC 22/59] Use tsc for time rather than rumpkernel clock_gettime()

From: George Dunlap The rumpkernel clock_gettime() drifts drastically when the system is overloaded. Switch to using a TSC timesource instead: * Use tsc_mode='native' in guest config * Read the host tsc from /proc/cpuinfo when starting a run * Pass it as an argument

[Xen-devel] [PATCH RFC 13/59] Add GPL headers / COPYING file (v2 only)

[Xen-devel] [PATCH RFC 17/59] controller: Collect and display statistics on WorkerSets

From: George Dunlap Introduce WorkerSetSummary, to contain WorkerSummary's and collect data for the set. For now "if false"-out reporting of individual worker averages; we can add this back in as an option later. Signed-off-by: George Dunlap

[Xen-devel] [PATCH RFC 03/59] controller: Initial attempt to generalize process / vm creation

From: George Dunlap Create a "Worker" interface, and have ProcessWorker implement that interface. Rename "Worker" to "WorkerReport" to make room for the interface. Signed-off-by: George Dunlap --- main.go | 45

[Xen-devel] [PATCH RFC 19/59] Add basic libxl framework, get domain cpu_time

From: George Dunlap Introduce libxl "Context" class with open, close, and dominfo. Create a global variable in xenworker.go to hold the context; open on first worker creation, close on last worker destruction. Add a new element to WorkerReport, Cputime, and print it

[Xen-devel] [PATCH RFC 26/59] Use kops rather than mops

From: George Dunlap 1 million operations on my test box takes about 3ms -- meaning the minimum granularity for how long to burn cpu is far longer than typical. Make this kops instead, giving us a minimum granularity of 3us. Update most of the default workers to have

[Xen-devel] [PATCH RFC 24/59] report: Lots of changes

From: George Dunlap Store raw worker reports in the worker summary for easy printing. Add "level" argument to textreport to easly switch between different levels of granularity. Report total throughput, time, and cputime for workers. When running, print plain time

[Xen-devel] [PATCH RFC 23/59] run: Don't collect results reported after command to stop guests is issued

From: George Dunlap Particularly on heavily-loaded systems, this can lead to skew as some guests have already stopped processing. Signed-off-by: George Dunlap --- run.go | 9 +++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff

[Xen-devel] [PATCH RFC 18/59] controller: Add cpupool global config

From: George Dunlap Define WorkerConfig for worker configuration, add "Pool" as a pool in which to place the worker (currently implemented in Xen only). Add WorkerConfig options at the WorkerSet, BenchmarkRun, and BenchmarkPlan levels; allow local levels to "override"

[Xen-devel] [PATCH RFC 44/59] libxl: Implement CpupoolCreate

From: George Dunlap Implement CpupoolCreate. For now, follow the lead of "xl cpupool-create", by automatically generating a new uuid each time a new cpupool is created, and by not allowing the user to attempt to set the poolid. This requires us to implement

[Xen-devel] [PATCH RFC 45/59] libxl: Implement Destroy, Add/Remove operations

From: George Dunlap Also: * Implement useful Bitmap operations: SetRange(), ClearRange(), IsEmpty(), and And(). * Normalize CpupoolInfo element naming. * Implement CpupoolMakeFree, which will scan through cpupools freeing the cpus in the map. Signed-off-by: George

[Xen-devel] [PATCH RFC 20/59] xenworker: Use libxl_domain_unpause rather than forking xl
