2019-02-25	tools/intel_gpu_top: Add support for stdout logging	Tvrtko Ursulin
	Two new output modes are added: listing of text data to standard out (-l on the command line), and dumping of JSON formatted records (-J), also to standard out. The first mode is selected automatically when non-interactive standard out is detected. Example of text output: Freq MHz IRQ RC6 Power IMC MiB/s RCS/0 BCS/0 VCS/0 VCS/1 VECS/0 req act /s % W rd wr % se wa % se wa % se wa % se wa % se wa 0 0 0 0 0.00 360 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 35 2 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 34 2 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 143 6 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 169 7 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 350 350 0 100 0.00 169 7 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 Example of JSON output: { "period": { "duration": 1002.525224, "unit": "ms" }, "frequency": { "requested": 349.118398, "actual": 349.118398, "unit": "MHz" }, "interrupts": { "count": 0.000000, "unit": "irq/s" }, "rc6": { "value": 99.897752, "unit": "%" }, "power": { "value": 0.000000, "unit": "W" }, "imc-bandwidth": { "reads": 149.683843, "writes": 6.104093, "unit": "MiB/s" }, "engines": { "Render/3D/0": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" }, "Blitter/0": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" }, "Video/0": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" }, "Video/1": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" }, "VideoEnhance/0": { "busy": 0.000000, "sema": 0.000000, "wait": 0.000000, "unit": "%" } } } v2: * Show example output in commit message. * Install signal handler to complete output on SIGINT.

2018-05-31	intel-gpu-top: Rewrite the tool to be safe to use	Tvrtko Ursulin
	intel-gpu-top is a dangerous tool which can hang machines due unsafe mmio register access. This patch rewrites it to use only PMU. Only overall command streamer busyness and GPU global data such as power and frequencies are included in this new version. For access to more GPU functional unit level data, an OA metric based tool like gpu-top should be used instead. v2: * Sort engines by class and instance. * Do not wait for one sampling period to display something on screen. * Move code out of the asserts. (Rinat Ibragimov) * Continuously adapt to terminal size. (Rinat Ibragimov) v3: * Change layout and precision of some field. (Chris Wilson) Eero Tamminen: * Use more user friendly engine names. * Don't error out if a counter is missing. * Add IMC read/write bandwidth. * Report minimum required kernel version. v4: * Really support 4.16 by skipping of missing engines. * Simpler and less hacky float printing. * Preserve copyright header. (Antonio Argenziano) * Simplify engines_ptr macro. (Rinat Ibragimov) v5: * Get RAPL unit from sysfs. * Consolidate sysfs paths with a macro. * Tidy error handling by carrying over and reporting errno. * Check against console height on all prints. * More readable minimum kernel version message. (Eero Tamminen) * Column banner for per engine stats. (Eero Tamminen) v6: * Man page update.

2016-03-03	man: rewrite manual pages in reStructuredText	Jani Nikula
	intel_reg.rst was the first man page written in reStructuredText. Follow suit with the rest of the man pages. Add a generated defs.rst include file for definitions such as intel-gpu-tools version. This replaces the MAN_SUBSTS sed script substitutions from xorg-macros for old man pages. Signed-off-by: Jani Nikula <jani.nikula@intel.com>
